  3. Agile Methodologies- The Development Landscape -

  4. Agile Requirements and the Product Backlog

  5. Requirements Gathering – High Level • Being true to the Agile Methodology you will need to account for: • Technical changes • Changing business needs • Process improvement • Enhancing the value of the application

  6. Traditional Requirements Gathering Process

  7. Agile Requirement Process

  8. Example: Requirements Board Postit Collections and User Stories

  9. How detailed should Agile Requirements be? Detailed enough for the team to start work from. Further details can be established and clarified during development.

  10. INVESTin Good Requirements Independent– Agile Requirements should be as independent as possible. Negotiable– Agile Requirements are not a contract. They are not detailed specifications. They are reminders of features for the team to discuss and collaborate to clarify the details near the time of development. Valuable – Agile Requirements should be valuable to the user (or owner) of the solution. They should be written in user language. They should be features, not tasks. Estimatable– Agile Requirements need to be estimated. They need to provide enough information to estimate, without being too detailed. Small – Agile Requirements should be small. Not too small. But not too big. Testable – Agile Requirements need to be worded in a way that is testable, i.e. not too subjective and to provide clear details of how the User Story will be tested.

  11. Key Principles for Agile Requirements Active user involvement is imperative Agile teams must be empowered to make decisions Requirements emerge and evolve as software is developed Product Owner involvement is key to success Enough’s enough – apply the 80/20 rule Cooperation, collaboration and communication

  12. Increasing Detail through Interaction over Time

  13. Sometimes Rarely 16% 19% Never Often 45% 13% Always 7% Often or always used: 20% Rarely or never used: 64% Getting Priorities Right… Features and functions used in a typical system Standish Group Study Reported at XP2002 by Jim Johnson, Chairman

  14. The Product Backlog

  15. Agile Requirement Process

  16. Agile Requirements Summary Agile Requirements combine written and verbal communications, supported with a picture where possible. Agile Requirements should describe features that are of value to the user, written in a user’s language. Agile Requirements detail just enough information. Details are deferred and captured through collaboration - just in time for development. Test cases should be written before development, when the User Story is written. Agile Requirements should be Independent, Negotiable, Valuable, Estimatable, Small and Testable.
