Agile Questions And Answers 74pm

1) As a tester what should be your approach when requirements change continuously? When requirement keeps changing, continuously agile tester should take following approach 

Write generic test plans and test cases, which focuses on the intent of the requirement rather than its exact details



To understand the scope of change, work closely with the product owners or business analyst



Make sure team understand the risks involved in changing requirements especially at the end of the sprint



Until the feature is stable, and the requirements are finalized, it is best to wait if you are going to automate the feature



Changes can be kept to a minimum by negotiating or implement the changes in the next sprint

2) List out the pros and cons of exploratory testing (used in Agile) and scripted testing?

Exploratory Testing

Scripted Testing

Pros - It requires less preparationEasy to modify when requirement changes – Works well when documentation is scarce - In case testing against legal or regulatory requirements it is very useful

Cons - Presenting progress and Coverage to project management is difficult - Test preparation is usually time-consuming- Same steps are tested over and again – When requirement changes it is difficult to modify

3) Explain the difference between Extreme programming and Scrum?

Scrum - Scrum teams usually have to work in iterations called sprints which usually last up to two weeks to one month long - Scrum teams do not allow change into their sprints - In scrum, the product owner prioritizes the product backlog but the team decides the sequence in which they will develop the backlog items - Scrum does not prescribe any engineering practices

Extreme Programing (XP) - XP team works in iteration that last for one or two weeks - XP teams are more flexible and change their iterations - XP team work in strict priority order, features developed are prioritized by the customer - XP does prescribe engineering practices

4) What is an epic, stories and task?   

Epic: A customer described software feature that is itemized in the product backlog is known as epic. Epics are sub-divided into stories Stories: From the client perspective stories are prepared which defines project or business functions, and it is delivered in a particular sprint as expected. Task: Further down stories are broken down into different task

5) Explain what is re-factoring? To improve the performance, the existing code is modified; this is re-factoring. During refactoring the code functionality remains same

6) Explain how you can measure the velocity of the sprint with varying team capacity? When planning a sprint usually, the velocity of the sprint is measured on the basis of professional judgement based on historical data. However, the mathematical formula used to measure the velocity of the sprint are, 

first – completed story points X team capacity: If you measure capacity as a percentage of a 40 hours weeks



Second – completed story points / team capacity: If you measure capacity in man-hours

For our scenario second method is applicable. 7) Mention the key difference between sprint backlog and product backlog? Product backlog: It contains a list of all desired features and is owned by the product owner Sprint backlog: It is a subset of the product backlog owned by development team and commits to deliver it in a sprint. It is created in Sprint Planning Meeting 8) In Agile mention what is the difference between the Incremental and Iterative development? Iterative: Iterative method is a continuous process of software development where the software development cycles are repeated (Sprint & Releases) till the final product is achieved. Release 1: Sprint 1, 2… n Release n: Sprint 1, 2….n Incremental: Incremental development segregates the system functionality into increments or portions. In each increment, each segment of functionality is delivered through cross-discipline work, from the requirements to the deployment. 9) Explain what is Spike and Zero sprint in Agile? What is the purpose of it? Sprint Zero: It is introduced to perform some research before initiating the first sprint. Usually this sprint is used during the start of the project for activities like setting development environment, preparing product backlog and so on. Spikes: Spikes are type of stories that are used for activities like research, exploration, design and even prototyping. In between sprints, you can take spikes for the work related to any technical or design issue. Spikes are of two types Technical Spikes and Functional Spikes. 10) What is test driven development?

Test driven development or TDD is also known as test-driven design. In this method, developer first writes an automated test case which describes new function or improvement and then creates small codes to that test, and later re-factors the new code to meet the acceptable standards. 11) Prototypes and Wireframes are widely used as part of? Prototypes and Wireframes are prototypes that are widely used as part of Empirical Design 12) Explain what is Application Binary Interface?

Across different system platforms and environments a specification defining requirements for portability of applications in binary form is known as Application Binary Interface 13) Explain in Agile, burn-up and burn-down chart?

To track the project progress burnup and burn down, charts are used Burnup Chart: It shows the progress of stories done over time Burndown Chart: It shows how much work was left to do overtime 14) Explain what is Scrum ban? Scrum ban is a software development model based on Scrum and Kanban. It is specially designed for project that requires frequent maintenance, having unexpected stories and programming errors. Using these approach, the team’s workflow is guided in a way that allows minimum completion time for each story or programming error. 15) What is story points/efforts/ scales? It is used to discuss the difficulty of the story without asg actual hours. The most common scale used is a Fibonacci sequence ( 1,2,3,5,8,13,….100) although some teams use linear scale (1,2,3,4….), Powers of 2 (1,2,4,8……) and cloth size (XS, S ,M,L, XL) 16) Explain what is tracer bullet? The tracer bullet is a spike with the current architecture, the current set of best practices, current technology set which results in production quality code. It is not a throw away code but might just be a narrow implementation of the functionality. 17) What is a test stub?

A test stub is a small code that replaces an undeveloped or fully developed component within a system being tested. Test stub is designed in such a way that it mimics the actual component by generating specifically known outputs and substitute the actual component. 18) What are the differences between RUP (Rational Unified Process) and Scrum methodologies? RUP - Formal Cycle is defined across four phases, but some workflows can be concurrent - Formal project plan, associated with multiple iterations is used. - Scope is predefined ahead of the project start and documented in the scope document. During the project, scope can be revised. - Artifacts include Scope Document, formal functional requirements package, system architecture document, development plan, test scripts, etc. - Recommended for long term, large, enterprise level projects with medium to high complexity

SCRUM - Each sprint is a complete cycle - No end to end project plan. Each next iteration plan is determined at the end of the current iteration - It uses a project backstead of scope scrum - Operational software is the only formal artifacts - Recommended for quick enhancements and organization that are not dependent on a deadline

19) Why Continuous Integration is important for Agile? Continuous Integration is important for Agile for following reasons 

It helps to maintain release schedule on time by detecting bugs or integration errors



Due to frequent agile code delivery usually every sprint of 2-3 weeks, stable quality of build is a must and continuous integration ensures that



In helps to maintain the quality and bug free state of code-base



Continuous integration helps to check the impact of work on branches to the main trunk if development work is going on branches using automatic building and merging function

20) What testing is done during Agile? The primary testing activities during Agile is automated unit testing and exploratory testing. Though, depending on project requirements, a tester may execute Functional and Nonfunctional tests on the Application Under Test (AUT).

1.

What’s the benefit of using Agile over conventional Waterfall methodology for developing software?

Benefit of Agile Methodology 

It provides greater visibility to stakeholder from the start of the sprint, which in turn provide early and ensures project success.



Risks are greatly reduced and handled in better way in agile.



Products can be delivered early.



Clients are more involved and have greater satisfaction.



Greater agility, changes could be incorporated early.



Development could be started early.

2.

What are the different meetings in Agile? What is purpose of Release Planning, Sprint Planning meetings, Scrum Meeting, Sprint Review Meeting, Retrospection?

Release Planning In this release plan is prepared, which include list of features that needs to be delivered, release date of software into Production, number of iterations/sprints for that release etc. Spring Planning In this product Owner presents the set of features he would like and the team asks questions to understand the requirements in sufficient detail to enable them to commit to delivering the listed features in sprint. Daily Scrum Meeting Daily Scrum Meeting is for answering the following 3 questions: 1. What have you done since yesterday’s meeting? 2. What are you going to get done today? 3. What obstacles do you need to be removed? Sprint Review It is demonstration of the new features the team has completed during the sprint; it is used to gather early . Sprint Retrospection It follows immediately after the sprint review. It is focused on the process, the way in which the Scrum team is working together, including their technical skills and the software development practices and tools they are using. In this meeting team discuss on following points: 1. What went wrong? 2. What went well? 3. What can be improved?

3.

How you do Estimation in Agile? How to estimate using Planning Poker?

In Agile often estimation is done using planning poker: 

Each member of team is given deck of card which contains stories points in Fibonacci sequence: 0, 1, 2, 3, 5, 8, 13...



Scrum Master lists the stories and provides brief overview of them. Team discusses and clarifies any questions/risks.



Each team member privately assigns a card representing his estimate of the size for the story.



Later on all estimates are revealed and people having low estimates and high estimates need to provide justification for the same and after discussion within team story point is finalized for use story. Same is repeated for all stories.

4.

What is Continuous Integration and why it is important for Agile? What are the software/tools available for the same?

Check this Continuous Integration 5.

What is difference between Product backlog & Sprint Backlog?

Product backlog is owned by the product owner, which contains list of all desired features. Sprint backlog is created in Sprint Planning Meeting. It is subset of product backlog which is owned by development Team, who commits it to deliver in a sprint. 6.

What is difference between Epic, stories & Tasks? Who should create stories & Task?

Stories defines business requirement from the client perspective and it is supposed to be delivered in particular sprint. Task: Stories are further broken down into different task from technical perspective. Epic is a group of related Stories, or it is large use story which cannot be completed in single Sprint. stories should be created by Product Owner as these are written from client perspective. Tasks should be created by someone from Development Team who is aware about them from technical perspective. 7.

What is Pair Programming? What’s the benefit of that?

As per Wiki Pair programming is defined as: “Pair programming is an agile software development technique in which two programmers work together at one workstation. One, the driver, writes code while the other, the observer or navigator, reviews each line of code as it is typed in. The two programmers switch roles frequently” Benefits of Pair Programming: 

It helps in business and technical knowledge transfer within the team.



It improves code quality and helps in building better design.



In short term there may be loss of productivity but it increase productivity of resource due to gain in business or technical knowledge.

8.

What is TDD (Test Driven Development)?

As per Wiki TDD is defined as: Test-DrivenDevelopment (TDD) is a software development process that relies on the repetition of a very short development cycle: first the developer writes an (initially failing) automated test case that defines a desired improvement or new function, then produces the minimum amount of code to that test, and finally refactors the new code to acceptable standards.

9.

What do you mean by Iterative and Incremental Development in Agile?

Iterative: In iterative development, software development is done in repeated cycles (Releases & Sprints).In each iteration planned use stories are designed, developed, tested and deployed for customer's . Release 1: Sprint 1, 2…n Release 1: Sprint 1, 2…n .. Release n: Sprint 1, 2…n Incremental: As per Wiki Incremental Development defined as: “Incremental development slices the system functionality into increments (portions). In each increment, a slice of functionality is delivered through cross-discipline work, from the requirements to the deployment. The unified process groups increments/iterations into phases: inception, elaboration, construction, and transition.”

10.

What is Burn-Down or Burn-Up Chart in Agile?

Burn Up and Burn Down charts are used to track project progress. Burnup Chart shows progress of stories done over time. X Axis: Time, Y Axis: no. of stories completed. Burndown Chart shows how much work was left to do over time. X Axis: Time, Y Axis: no. of stories remaining. 11.

What do you mean by Velocity in Agile?

As per Wiki Velocity is defined as: “The velocity is calculated by counting the number of units of work completed in a certain interval, the length of which is determined at the start of the project” Velocity is used in Agile to calculate the no. of stories that can be delivered in particular sprint based on previous delivery. 12.

What does Task board indicates in Agile?

Task board is used to track progress in agile. Generally it has following columns:

Use Story: Use Story under consideration for current sprint. To Do: Tasks that needs to be picked up. In Progress: Tasks that are currently in progress. To : Tasks that needs to verified/tested. Done: Tasks that are completed.

Frequently used agile methodology interview questions In what does the agile testing(development) methodology differs from the other testing (development) methodologies? Anytime applying agile methodology, the testers (developers) ensure that the whole process of testing (development) is broke into as small steps as possible and just a small unit of code is tested (developed) in each of this steps. The team of testers (developers) is communicating consistently the results of their work, and change the short term strategy and even the development plan on the go, based on the results of agile testing. Agile methodology encourages flexible and rapid response to change which should lead to a better end result. Can agile methodology be applied also in other than software testing and development projects? While asking these sort of questions, employers try to recognize if you really understand the benefits of this methodology and can see a practical application in various areas of business. To state that this methodology can be, and maybe even should be, applied in all the instances and test cases where we have insufficient entry data, or work in an unknown area, or simply work within a small team, or where many unpredictable variables take place, is a good answer. It is in fact used quite commonly in bio-medicine, biochemistry or physics. Anyway, it could be used in many other areas too. Just let your imagination work and you’ll find a good answer…

Are you able to name five main characteristics of agile methodology? Every person can approach agile methodology from a different angle. The employer tries to find out what your opinion is, and if it is the one they are looking for. So in fact, the right answer really depends on your point of view. However, if you look for characteristics that are usually “positive” for the company, you should do well with things like cross-functional team composition, face-to face communication, solving problems immediately after these are identified, working solution as a primary metric of progress. If you do not like our suggestions, you will have to figure out something on your own. Describe a situation when you personally used the agile methodology (or was a part of a team that used it). This question is very important. One little experience is more useful than the entire book of theory. Before the interview, think carefully about your own application of agile methodology. If you can not find any example in your professional life, try to find it in personal life. Think about it in advance, prepare a situation you will talk about later and focus on the positive results associated with the implementation of AM in your project. Doing it, you should be well prepared for all these practical questions. We wish you good luck! Sample Agile Foundation Examination Questions: 1.

Workshops held at the beginning and the end of every iteration (timebox) allow the team to adapt the product specification 57. What do all Agile approaches have in common? A. A prescribed, fixed iteration (timebox) length B. Iterative development and incremental delivery C. A strict focus on on-time delivery D. A large set of clearly defined roles 58. What is one difference in responsibility between a Project Manager and a Scrum Master (Team Leader) in an Agile project? A. None. It's basically the same. Scrum Master (or Team Leader) is just a better term than Project Manager in an Agile project B. The Project Manager creates the detailed delivery plans while the Team Leader monitors execution within the team C. Project Manager communicates with project governance authorities when necessary D. The Project Manager monitors the realisation of benefits in the business case. 59. How could you benefit from having an End Representative in your development team? A. End s should NOT be in the development team. Requirements are always communicated to the developers by the Product Owner, who is part of the customer team B. The End Representative will be solely responsible for acceptance tests within the team C. The End Representative assures that stories are documented properly D. The End Representative will be able to clearly tell the developers what will work for an end 60. The responsibilities of a Product Owner will include … A. Business processes diagramming B. Prioritizing requirements C. Managing the project budget D. All of these How to Choose Quality Candidates/Consultants for Your Large Company Agile Initiative Daryl Kulak & Anita Shankar, http://www.perficient.com/

We created this set of questions to help corporate managers select Agileexperienced consultants and candidate employees for project work. Assembling a team of qualified Agile people is one thing, but the fact that

some Agile practices and principles mean different things to different people makes it even harder to succeed in staffing your initiatives. A consultant or potential employee who has great Agile experience in small product companies may be exactly the wrong type of person to help you inside a large corporation. An Agile evangelist from a small product company may actually be horrified by some of the compromises that are absolutely necessary in your large company environment. We developed this questionnaire to make those distinctions. Depending on the role you are interviewing for, you may want to leave certain questions out or perhaps add some of your own. Certainly there will be questions you want to ask about things like the person’s outlook towards businesspeople and technical people working closely together, which is important no matter whether the project is waterfall or Agile. 1. How long were the iterations (or sprints) on the projects you worked on? Agile project methodology moves at a fast pace and you should already have a good idea of the length of the iterations for the pending project. Answers of between 1-week to 3-weeks are ideal. If your candidate has worked on Agile projects which have long iterations (4 weeks or longer), or wildly variable-length iterations, it will make sense to determine if this person is comfortable with the iterations as defined for your project. A steady set of fixed-length iterations that are fairly short is best. The theory that big companies need longer iterations is not based in fact. We’ve done many big company projects in the 1 to 2 week iteration range. 2. Are you a Certified Scrum Master (CSM)? If so, how do you view the way Scrum projects need to be organized? Often we use certifications as a golden way to qualify candidates. But be somewhat careful with people who have gone through the Certified Scrum Master (CSM) training. The goal here is to make sure that your project team member is comfortable with structure as each iteration progresses. Is she comfortable working with a project manager, or communicating to a team lead? Working inside a large corporation, you personally might feel that a project manager or team lead position is required on all but the smallest effort. But certain Agile consultants will insist that project managers are no longer necessary under Agile because teams will "self

organize." Steer clear of these candidates unless that is clearly the direction you want to go. Does your organization have defined roles and career paths like project manager, tester, business analyst, etc.? Do you have a strategy for muddying those career paths for the employees you bring onto this Agile initiative? If so, great. If not, avoid the candidates who tell you there is no alternative to self-organization. If the person is not a CSM, you may still encounter these issues, so pursue the line of questioning either way. NOTE: There is nothing systemically wrong with self-organization, but as a hiring manager, you need to know what your own strategy is for Agile adoption and then hire accordingly. I personally haven’t met many corporate managers who are terribly comfortable with self-organizing teams. 3. Did you use automated test tools on your projects? Explain how that worked. Agile project team should have experience (or at the very least, the desire) to use automated testing tools for regression and performance testing of each iteration. At the end of each iteration you want to have something that your customer/client can "see." Automated testing allows quick identification and isolation of development defects as well as the ability to test development work completed in previous iterations. Expect the candidate to talk about automated regression testing, continuous integration and testing and even performance testing techniques and tools. Also expect them to discuss the need for manual testing as well as automated testing, due to the ever-changing nature of the code base in Agile. 4. Have you done continuous integration on a project before? Describe. Here you want to get a pretty detailed explanation of how the candidate has used continuous integration on previous projects. Continuous integration is a set of automated build, integration and test steps that executes against the code base in a configuration management repository. For instance, if you were using Java and CVS, the CVS repository would have a set of triggers that automatically built, integrated and unit tested the code often, perhaps each night, perhaps a few times a week, or even

every time someone checked in new code. Each of these is a valid continuous integration story. 5. Did your iterations overlap? For instance, were the testers still testing Iteration 6 while Iteration 5 was being designed/developed? There are many views of how iterative/incremental projects should run under Agile. Overlapping iterations is certainly one strategy. The danger is to pay attention to the candidate if they say that "iterations should never overlap." This may tell you that the candidate is used to having what is called "multidisciplinary teams." This type of team consists of a set of generic team who all have the skills and enthusiasm for requirements, design, coding and testing and who each participate in those activities almost equally. If your company has defined roles (business analyst, test analyst, etc.) and career paths then this candidate may have a tough time fitting into your structure. They will want BAs to code and testers to do design. Is that okay? It is your decision. Again, nothing wrong with multidisciplinary teams, but your organization must be able to handle the change if you decide to go that way. 6. Have you used story cards or use cases? Explain how that worked for the team. Often, Agile projects are associated with the use of story cards. However, our goal is to simply understand if our potential team member is comfortable implementing a project (deg, developing, testing, etc) with business information which has been documented in some way. The requirements (story cards or use cases or a combination of both) should have enough information to provide guidelines for developing and testing and also allow the development team to come up with a creative and effective solution. By asking this question, you want to understand if your potential team member is comfortable working with requirements in a structured development environment (versus brief summaries from which the developers build code). Again, this is a matter of matching the Agile candidate’s experience with your organization’s needs. 7. How did you manage traceability of the requirements to testing? The point here is to make sure testing goes all the way back to requirements for validation. Not only is it important to test that the

functionality a developer has created during an iteration actually functions, it is also important to determine if it functions the way the business wanted it to function. Does it meet the requirements defined in the story card / use case? Your team should understand the importance of this concept and if they understand and accept traceability, you should be able to count on this person to help you meet project goals. 8. How comfortable are you with ever-changing requirements? Many development methodologies specify that requirements are locked down at the beginning of a project. Although that is not the case in Agile, it does not mean that requirements are loosey-goosey! The advantage of Agile and its short iterations is that it is easy to quickly recognize that work is not progressing as desired – that what the customer ‘asked for’ is not what they ‘wanted’ – and the requirements must be changed. Team should be able to handle such changes on an Agile project. It shouldn’t be so tied to code, a story card or any other component of work that prevents providing a solution which meets the customer’s needs. The general idea is that requirements can change a lot at the beginning of the release, and very little at the end. 9. Did people play multiple roles on your development team? Here we get back to multidisciplinary teams. What you are really trying to understand from this question is how well an individual would fit into your organization and your style of Agile development. If your organization is one in which individuals select a specialized role (such as Java Developer) as part of their career path, your interview candidate may have difficulty on your team if she is more comfortable working in Agile projects where she has had the ability to play multiple roles (Scrum for example). Conversely, if your candidate’s primary experience was developed on projects where roles were clearly defined and individuals did not work in multiple capacities, then he may be uncomfortable in an organization where team can play any role on a project to achieve its end goal. You must choose the candidate which fits your organization well and is flexible enough to suit the needs of your Agile project implementation. Two particular roles that are more easily interchanged are business analysts and testers, other roles are harder to be "multifunctional." 10. What project management tools were used on your project?

This question is more for Agile project managers. Do you have corporate PM tool standards? If so, this question becomes quite important. Agile has a new breed of PM tools including Rally Software, Version One and XPlanner. These tools bear no resemblance to the waterfall PM tools like MS-Project or Clarity. If your candidate is more comfortable using one of these Agile PM tools, try to identify if they will be able to fit their Agile project plans (and issues, milestones, change requests, etc.) into your company’s structure. 11. Can you explain the purpose of a burndown chart? This is more of a question for candidate project managers, although all Agile people should know the answer. A burndown chart is a graph that shows the progress of the team in of work "burned through." The work is usually put in of a set of "story points" which represent functionality. Once a piece of functionality is coded and tested and reviewed by the , it is considered to be "burned" and the graph will reflect this. The graph should show a steady movement down until it is clear that the team will have completed the story point backlog by the release date. There is also a variation called a "burnup chart" that works the same way but can handle scope changes more easily than the burndown variety. Again, you want to see how the candidate will link their burndown/burnup chart into your overall project management structure. 12. What does project velocity mean? This is a PM question, but most Agile people should know the answer. Project velocity is the rate at which a team is "burning" through story points, so a possible velocity might be "30 story points per iteration." That means that so far, the team has been able to identify, code and test 30 units of functionality (story points) in an average iteration and can expect to do about that much in future iterations, giving a fairly good view towards what can be accomplished by a release date. Hopefully, these twelve questions can be a good start for your qualification process in bringing in new Agile consultants or candidate employees. Our hope is that you can build a highly-qualified team that will fit in well with your corporate development process, culture and PM standards. References:

Succeeding with Agile

Kanban Kanban is a lean approach to agile software development. Actually, Kanban means many things. Literally, Kanban is a Japanese word that means “visual card”. At Toyota, Kanban is the term used for the visual & physical signalling system that ties together the whole Lean Production system. Most agile methods such as Scrum and XP are already well aligned with lean principles. In 2004, however, David Anderson pioneered a more direct implementation of Lean Thinking and Theory of Constraints to software development. Under the guidance of experts such as Don Reinertsen, this evolved into what David called a “Kanban system for software development”, and which most people now simply refer to as “Kanban”. So while Kanban as applied to software development is new, Kanban as used in Lean Production is over a half century old.

Does Kanban matter to me? Do any of these sound familiar? o

“We’ve done Scrum for a long time now and our process improvement has levelled off. How can we take our process to the next level?”

o

“Our needs and priorities shift on a daily basis”

o

“We don’t like fixed-length, fixed-commitment iterations”

o

“We are spending too much time planning and estimating” If so, read on. Along with Scrum and XP, Kanban should be part of the process toolkit of any agile company. The choice of where & when to use it can only be made by you though.

How does Kanban work? There are many flavors, but the core of Kanban means: 1.

2.

Visualize the workflow o

Split the work into pieces, write each item on a card and put on the wall.

o

Use named columns to illustrate where each item is in the workflow.

Limit WIP (work in progress) – assign explicit limits to how many items may be in progress at each workflow state.

3.

Measure the lead time (average time to complete one item, sometimes called “cycle time”), optimize the process to make lead time as small and predictable as possible.

This is a direct implementation of a lean pull scheduling system. Here’s an example of a simple Kanban board, with WIP limits in red.

Here’s a more complex one (see Kanban kick-start example for a closer look & description)

What are the benefits of Kanban? Some commonly observed benefits are: o

Bottlenecks become clearly visible in real-time. This leads people to collaborate to optimize the whole value chain rather than just their part.

o

Provides a more gradual evolution path from waterfall to agile software development, thereby helping companies that previously have been unable or unwilling to try agile methods.

o

Provides a way to do agile software development without necessarily having to use timeboxed fixed-commitment iterations such as Scrum sprints. Useful for situations where sprints don’t make much sense, such as operations and teams with a high rate of uncertainty and variabilty.

o

Tends to naturally spread throughout the organization to other departments such as HR and sales, thereby increasing visibility of everything that is going on at the company.

Can I combine Kanban with my current process? Yes. In fact, you should combine it. In Kanban the first step is to visualize your current process, just as it is, in order to see where the bottlenecks are. Then you introduce WIP limits and start a path of evolution that may or may not modify or replace your current process over time. See “Kanban & Scrum – making the most of both”, where Henrik Kniberg and Mattias Skarin illustrate how Kanban and Scrum relate to each other.

Where is Kanban used? Our coaches at Crisp have helped several clients use Kanban to improve their process. In fact, a surprising number of our clients have found that Kanban is an extremely useful complement (or sometimes even a replacement) to other popular agile methods such as Scrum. Typical manager comment: “It really helps us visualize our projects and situation”. There is also an increasing number of case studies available atwww.limitedwipsociety.org. Here are a few examples: o o o

Common misunderstandings about Kanban o o o o o o o o

Myth: With Kanban you don’t use iterations Fact: With Kanban iterations are optional. Do it only if you have a need for it in your context. Myth: With Kanban you don’t estimate Fact: With Kanban estimation is optional. Do it only if you have a need for it in your context. Myth: Kanban is better than Scrum/XP/RUP/whatever Fact: Kanban is just a process tool, and there is no such thing as a universally good or bad tool. It all depends on your context. See this article for more info. Myth: Kanban is a drop-in replacement to Scrum/XP/RUP/whatever Fact: Kanban is just about managing workflow. It hardly replaces anything. What it does do, however, is drive change. In Kanban you start with whatever process you have, visualize it, introduce WIP limits, and then evolve from there.

Scrum Scrum and Kanban are both empirical in the sense that you are expected to experiment with the process and customize it to your environment. In fact, you have to experiment. Neither Scrum nor Kanban provide all the answers – they just give you a basic set of constraints to drive your own process improvement.

Scrum Summary Scrum is an iterative, incremental framework for projects and product or application development. It structures development in cycles of work called Sprints. These iterations are no more than one month each, and take place one after the other without pause. The Sprints are timeboxed – they end on a specific date whether the work has been completed or not, and are never extended. At the beginning of each Sprint, a cross-functional team selects items 5 (customer requirements) from a prioritized list. The team commits to complete the items by the end of the Sprint. During the Sprint, the chosen items do not change. Every day the team gathers briefly to inspect its progress, and adjust the next steps needed to complete the work remaining. At the end of the

Sprint, the team reviews the Sprint with stakeholders, and demonstrates what it has built. People obtain that can be incorporated in the next Sprint. Scrum emphasizes working product at the end of the Sprint that is really “done”; in the case of software, this means code that is integrated, fully tested and potentially shippable. A major theme in Scrum is “inspect and adapt.” Since development inevitably involves learning, innovation, and surprises, Scrum emphasizes taking a short step of development, inspecting both the resulting product and the efficacy of current practices, and then adapting the product goals and process practices. Repeat forever. Like any tools, Scrum and Kanban are neither perfect nor complete. They don’t tell you everything that you need to do, they just provide certain constraints & guidelines S.No 1.

2.

3.

Scrum It constrains you to have timeboxed iterations and cross-functional teams Scrum prescribes 3 roles:  Product Owner (sets product vision &priorities)  Team (implements the product)  Scrum Master (removes impediments and provides process leadership) It limits WIP per iteration

Kanban It constrains you to use visible boards and limit the size of your queues i.e. limit WIP(Work-in-progress) Kanban doesn’t prescribe any roles at all. That doesn’t mean you can’t or shouldn’t have a Product Owner role in Kanban! It just means you don’t have to. In both Scrum and Kanban you are free to add whatever additional roles you need. It limits WIP per workflow state

Points to be noted: 1. Process = how you work. Tool = anything used as a means of accomplishing a task or purpose. Scrum and Kanban are process tools in that they help you work more effectively by, to a certain extent, telling you what to do. Which tool is better depends upon your context. For a given situation, a particular tool is better 2. No tool is complete and no tool is perfect. Like any tools, Scrum and Kanban are neither perfect nor complete. They don’t tell you everything that you need to do, they just provide certain constraints & guidelines. For example, Scrum constrains you to have timeboxed iterations and cross-functional teams, and Kanban constrains you to use visible boards and limit the size of your queues.

3. Interestingly enough, the value of a tool is that it limits your options. A process tool that lets you do anything is not very useful. We might call that process “Do Whatever” or how about “Do The Right Thing” 4. Using the right tools will help you succeed, but will not guarantee success. It's easy to confuse project success/failure with tool success/failure. A project may succeed because of a great tool. A project may succeed despite a lousy tool. A project may fail because of a lousy tool. A project may fail despite a great tool..

5. Prescriptive means “more rules to follow” and adaptive means “fewer rules to follow”. 100% prescriptive means you don’t get to use your brain, there is a rule for everything. 100% adaptive means Do Whatever, there are no rules or constraints at all. 6. Agile methods are sometimes called lightweight methods, specifically because they are less prescriptive than traditional methods. Scrum and Kanban are both highly adaptive, but relatively speaking, Scrum is more prescriptive than Kanban. Scrum gives you more constraints, and thereby leaves fewer options open. For example Scrum prescribes the use of timeboxed iterations, Kanban doesn’t 7. XP (eXtreme Programming) is pretty prescriptive compared to Scrum. It includes most of Scrum + a bunch of fairly specific engineering practices such as test-driven development and pair programming 8. One of the main differences between Scrum and RUP is that in RUP you get too much, and you are supposed to remove the stuff you don’t need. In Scrum you get too little, and you are supposed to add the stuff that is missing. Kanban leaves almost everything open. The only constraints are Visualize Your Workflow and Limit Your WIP. Just inches from Do Whatever, but still surprisingly powerful. 9. Don’t limit yourself to one tool. Mix and match the tools as you need! I can hardly imagine a successful Scrum team that doesn’t include most elements of XP for example. Many Kanban teams use daily standup meetings (a Scrum practice). Some Scrum teams write some of their backlog items as Use Cases (a RUP practice) or limit their queue sizes (a Kanban practice). Whatever works for you.

10. The general mindset in both Scrum and Kanban is “less is more”. So when in doubt, start with less.
