Customized Scrum

  1. 1. Customized Scrum Process Abdul Karim Software Engineer Dhaka, Bangladesh
  2. 2. Startup first time in Scrum• It is really very difficult to follow 100% of scrum process in real life product/project development.• Did you face this issues ? I think most of you will answer YES.• So what we need to do is customize the scrum in your own way.
  3. 3. • Management suddenly assigned me as Product Owner and Scrum Master, but I do not have previous experience in Scrum at all.• My traditional process is estimate task and make a schedule in Microsoft project plan.• So I learn Scrum and start in my own way.
  4. 4. • I will first discuss about Scrum and then will show you how I follow & implement in practically .
  5. 5. Scrum in 100 words• Scrum is an agile process that allows us to focus on delivering the highest business value in the shortest time.• It allows us to rapidly and repeatedly inspect actual working software (every two weeks to one month).• The business sets the priorities. Teams self-organize to determine the best way to deliver the highest priority features.• Every two weeks to a month anyone can see real working software and decide to release it as is or continue to enhance it for another sprint. ---- By Internet

  7. 7. What is Sprints?• Scrum projects make progress in a series of “sprints” – Analogous to Extreme Programming iterations• Typical duration is 2–4 weeks or a calendar month at most• A constant duration leads to a better rhythm• Product is designed, coded, and tested during the sprint
  8. 8. Sequential vs. overlapping developmentRequirements Design Code Test Rather than doing all of one thing at a time... ...Scrum teams do a little of everything all the time Source: “The New New Product Development Game” by Takeuchi and Nonaka. Harvard Business Review, January 1986.
  9. 9. Product owner• Define the features of the product• Decide on release date and content• Be responsible for the profitability of the product (ROI)• Prioritize features according to market value• Adjust features and priority every iteration, as needed• Accept or reject work results
  10. 10. The ScrumMaster• Represents management to the project• Responsible for enacting Scrum values and practices• Removes impediments• Ensure that the team is fully functional and productive• Enable close cooperation across all roles and functions• Shield the team from external interferences
  11. 11. The team• Typically 5-9 people• Cross-functional: – Programmers, testers, user experience designers, etc.• Members should be full-time • May be exceptions (e.g., database administrator)
  12. 12. The team• Teams are self-organizing – Ideally, no titles but rarely a possibility• Membership should change only between sprints
  13. 13. Team Sprint planning meetingcapacity Sprint prioritizationProduct • Analyze and evaluate product Sprintbacklog backlog goal • Select sprint goalBusinessconditions Sprint planning • Decide how to achieve sprint goalCurrent (design) Sprintproduct • Create sprint backlog (tasks) from backlog product backlog items (user stories / features)Technology • Estimate sprint backlog in hours
  14. 14. Sprint planning• Team selects items from the product backlog they can commit to completing• Sprint backlog is created – Tasks are identified and each is estimated (1-16 hours) – Collaboratively, not done alone by the ScrumMaster• High-level design is consideredAs a vacation planner, I wantto see photos of the hotels. Code the middle tier (8 hours) Code the user interface (4) Write test fixtures (4) Code the foo class (6) Update performance tests (4)
  15. 15. The daily scrum• Parameters – Daily – 15-minutes – Stand-up• Not for problem solving – Whole world is invited – Only team members, ScrumMaster, product owner, can talk• Helps avoid other unnecessary meetings
  16. 16. Everyone answers 3 questions 1 What did you do yesterday? 2 What will you do today? 3 Is anything in your way?• These are not status for the ScrumMaster – They are commitments in front of peers
  17. 17. The sprint review• Team presents what it accomplished during the sprint• Typically takes the form of a demo of new features or underlying architecture• Informal – 2-hour prep time rule – No slides• Whole team participates• Invite the world
  18. 18. Sprint retrospective• Periodically take a look at what is and is not working• Typically 15–30 minutes• Done after every sprint• Whole team participates – ScrumMaster – Product owner – Team – Possibly customers and others
  19. 19. Start / Stop / Continue• Whole team gathers and discusses what they’d like to: Start doing Stop doing This is just one of many ways to Continue doing do a sprint retrospective.
  20. 20. Product backlog • The requirements • A list of all desired work on the project • Ideally expressed such that each item has value to the users or customers of the product • Prioritized by the product owner • Reprioritized at the start ofThis is the each sprintproduct backlog

  22. 22. The sprint goal • A short statement of what the work will be focused on during the sprint Life Sciences Support features necessary forDatabase Application population genetics studies.Make the application run on SQLServer in addition to Oracle. Financial services Support more technical indicators than company ABC with real- time, streaming data.
  23. 23. Managing the sprint backlog• Individuals sign up for work of their own choosing – Work is never assigned• Estimated work remaining is updated daily
  24. 24. Managing the sprint backlog• Any team member can add, delete or change the sprint backlog• Work for the sprint emerges• If work is unclear, define a sprint backlog item with a larger amount of time and break it down later• Update work remaining as more becomes known

  28. 28. Scalability• Typical individual team is 7 ± 2 people – Scalability comes from teams of teams• Factors in scaling – Type of application – Team size – Team dispersion – Project duration• Scrum has been used on multiple 500+ person projects
  29. 29. Scrum Practices Tools• eScrum Template (MSF)• iceScrum (opensource)
  30. 30. Microsoft eScrum Template• Released on 6/13/07 (and again on 7/11/07) & can feel a bit rough at times• 1.1 released 8/9/2008 for TFS2008 – Much improved install experience over 1.0• But web UI is compelling in that it: – Is easier for non-VS.NET users to grasp – Provides reasonable flow to facilitate Scrum sprint- planning (as opposed to TFS Web Access)• Web UI allows parallel maintenance of Scrum- based work items with VS.NET/Team Explorer
  31. 31. Microsoft eScrum Template• Released on 6/13/07 (and again on 7/11/07) & can feel a bit rough at times• 1.1 released 8/9/2008 for TFS2008 – Much improved install experience over 1.0• But web UI is compelling in that it: – Is easier for non-VS.NET users to grasp – Provides reasonable flow to facilitate Scrum sprint- planning (as opposed to TFS Web Access)• Web UI allows parallel maintenance of Scrum- based work items with VS.NET/Team Explorer
  32. 32. Microsoft eScrum Template• Microsoft will continue to invest in MSF for Agile/CMMI – the MSF team continues to believe there is value they can bring with that process – Expect that MSF will more formally integrate engineering disciplines, especially those supported by Team System tooling• eScrum is not currently supported (as MSF would be) – it is offered “as is”
  33. 33. eScrum – what do you get? • Bugs are distinct from Sprint Tasks (though they may be linked) • No process guidance as such. For scrum reference, see: • See http://yourserver/eScrum/help/helpwindow.aspx for detail on using eScrum itself • Sharepoint Portal has configured lists for things like risks, product owner to-dos, etc.

  37. 37. Do we really need to follow Scrum?• Now we will discuss about advantages and disadvantages of scrum, because we must know weather we need to follow scrum for my project and what is the impact of Scrum in Project Deadline.
  38. 38. Scrum Advantages• Agile scrum helps the company in saving time and money.• Scrum methodology enables project’s where the business requirements documentation is hard to quantify to be successfully developed.• Fast moving, cutting edge developments can be quickly coded and tested using this method, as a mistake can be easily rectified.• It is a lightly controlled method which insists on frequent updating of the progress in work through regular meetings. Thus there is clear visibility of the project development.• Like any other agile methodology, this is also iterative in nature. It requires continuous feedback from the user.• Due to short sprints and constant feedback, it becomes easier to cope with the changes.
  39. 39. Scrum Advantages• Daily meetings make it possible to measure individual productivity. This leads to the improvement in the productivity of each of the team members.• Issues are identified well in advance through the daily meetings and hence can be resolved in speedily• It is easier to deliver a quality product in a scheduled time.• Agile Scrum can work with any technology/ programming language but is particularly useful for fast moving web 2.0 or new media projects.• The overhead cost in terms of process and management is minimal thus leading to a quicker, cheaper result.• In a nutshell this means that you can get development started fast, but with the caveat that the project scope statement is "flexible" and not fully defined. Hence this can be one of the major causes of scope creep if not managed properly.
  40. 40. Scrum Disadvantages• Agile Scrum is one of the leading causes of scope creep because unless there is a definite end date, the project management stakeholders will be tempted to keep demanding new functionality is delivered.• If a task is not well defined, estimating project costs and time will not be accurate. In such a case, the task can be spread over several sprints.• If the team members are not committed, the project will either never complete or fail.• It is good for small, fast moving projects as it works well only with small team.
  41. 41. Scrum Disadvantages• This methodology needs experienced team members only. If the team consists of people who are novices, the project cannot be completed in time.• Scrum works well when the Scrum Master trusts the team they are managing. If they practice too strict control over the team members, it can be extremely frustrating for them, leading to demoralisation and the failure of the project.• If any of the team members leave during a development it can have a huge inverse effect on the project development• Project quality management is hard to implement and quantify unless the test team are able to conduct regression testing after each sprint.
  42. 42. • I used icescrum because of its license issue.• It is really helpful for task tracking and see all task status in at a glance• Deployment is so easy.
