  4. 4. The Agile Manifesto We are uncovering better ways of developing software by doing it and helping others do it. Individuals and interactions over processes and tools Working software over comprehensive documentation Customer collaboration over contract negotiation Responding to change over following a plan That is, while there is value in the items on the right, we value the items on the left more.

  5. 5. 12 Principles of Agile Software 1. Our highest priority is to satisfy the customer through early and continuous delivery of valuable software. 2. Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage. 3. Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale. 4. Business people and developers must work together daily throughout the project. 5. Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done. 6. The most efficient and effective method of conveying information to and within a development team is face-to-face conversation. 7. Working software is the primary measure of progress. 8. Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely. 9. Continuous attention to technical excellence and good design enhances agility. 10. Simplicity the art of maximizing the amount of work not done--is essential. 11. The best architectures, requirements, and designs emerge from self-organizing teams. 12. At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly. Source: www.agilemanifesto.org www.torak.com

  16. 16. Origins ... Scrum ● 1986, Hirotaka Takeuchi and Ikujiro Nonaka described a new approach to commercial product development "holistic or rugby approach" ● 1991, DeGrace and Stahl first referred to this as the scrum approach. Ken Schwaber used such an approach at his company, Advanced Development Methods, and Jeff Sutherland, with John Scumniotales and Jeff McKenna, developed a similar approach at Easel Corporation, and were the first to refer to it using the single word Scrum. ● 1995, Sutherland and Schwaber jointly presented a paper describing the Scrum methodology ● 2001, Ken Schwaber teamed up with Mike Beedle to describe the method in the book "Agile Software Development with Scrum". XP - Extreme Programming ● created by Kent Beck during his work on the Chrysler Comprehensive Compensation System (C3) payroll project, who worked with Don Wells, Ron Jeffries, Martin Fowler and Chet Hendrickson ● takes software development "best practices" to extreme levels Kanban for development ● Japanese for "signboard" ● Taiichi Onho developed 1940/1950 kanbans to control production between processes and to implement Just n Time (JIT) manufacturing at Toyota manufacturing plants in Japan. ● 2003, David J. Anderson formulated the Kanban Method as an approach to incremental, evolutionary process and systems change for organizations www.torak.com

  18. 18. Scrum ● focus on delivering the highest business value in the shortest time ● allows to rapidly and repeatedly inspect actual working software ● the business sets the priorities & teams self-organize to determine the best way to deliver the work ● every sprint (1-4 weeks) anyone can see real working software and decide to release it as is, or continue to enhance it for another sprint www.torak.com

  23. 23. Kanban - 3 basic principles 1. Start with what you do now ● Kanban does not prescribe a specific set of roles or process steps 2. Agree to pursue incremental, evolutionary change ● continuous small changes that stick vs. sweeping changes that fail due to resistance and fear in the organization 3. Respect the current process, roles, responsibilities & titles ● gain support, reduce fear/resistance to change and experience the benefits as a team Kanban Board www.torak.com
  24. 24. Kanban - 5 Core Properties 1. Visualize the workflow ● Kanban literally means "signboard" or "billboard" 2. Limit Work In Process (WIP) ● use a pull system - establish and respect your ideal capacity 3. Manage Flow ● monitor, measure and report the flow of work through each state 4. Make Process Policies Explicit ● describe the process accurately in order to improve it 5. Improve Collaboratively ● using models & the scientific method (empirical) to implement continuous, incremental and evolutionary changes Kanban Board www.torak.com

  26. 26. Kanban: Start 1 a b to do in process done Start with a simple task board with 3 columns: to do, in process and done. Each card represent a work item in the current scope. Names can be associated with the cards. The key is to setup an easy way to visualize the work, and create an area for social interactions. c www.torak.com
  27. 27. Kanban: Start 2 a b to do in process done Start with a simple task board with 3 columns: to do, in process and done. Each card represent a work item in the current scope. Names can be associated with the cards. The key is to setup an easy way to visualize the work, and create an area for social interactions. b a to do in process done A problem with such a simplistic board, is the lack of rules and the concept of time- boxing. A typical problem is accumulating too much work in progress (WIP). Kanban is more than just adding work items on a board, it's also applying a PULL process. a b a b a c c c a c www.torak.com

Kanban is more than just adding work items on a board, it's also applying a PULL process. a b a b a c c c a to do in process done To truly embrace Kanban, we must regulate the volume of cards on the board. This can easily be accomplished by identifying clear thresholds associated to better defined stages of work (columns). Another improvement is to set a multi-tasking limit per user (2) and using late binding of tasks to owners. Note that not all team members must have 2 tasks with their names, this is a maximum of 2. b c a ready 2 5 a c c www.torak.com

Team member A completes a card and moves it to the "done" column. 2. Team member A pulls a new card from the "ready" column and starts working on it by placing it in the "in process" column. 3. The team responds to the pull event and selects the next priority card by moving it to the "ready" column. www.torak.com
