  4. 4. Group Workshop What are the top challenges we face with Requirements on a project? What are the most common issues that cause project challenges?  Discuss this with others next to you and prepare some answers to share with all of us. 4
  5. 5. Common Challenges with Requirements  Limited access to stakeholders  Not thinking outside of the „current‟ box  Conflicting priorities  Too much focus on one type of  Customers don‟t know what they requirement want  Not separating the What from the  Customers change their mind How  Getting the RIGHT SMEs  Developers don‟t understand the  Missing requirements problem domain  Jumping into the details too early  No clear definition of „Done‟  Moving from Abstract to Concrete Copyright© 2010 Sally Elatta 5 5
  6. 6. Addressing the Challenges with Requirements Gathering  Must Improve: Designing a process for requirements gathering so that you gather:  The Right Level of Requirement.  At the Right Time.  From the Right SME.  Using the Right elicitation/modeling techniques. Defining „Acceptance Tests‟ as core requirements and input into development. Engagement level of Product Owners and SMEs. Early and continuous user acceptance testing. Engagement level of Product Owner.

  13. 13. Requirements Brainstorming Techniques • Epics, User • To brainstorm a large number of Stories user stories. • Story Writing • Goal is breadth, not Workshop depth. • Post-it Note Brainstorming • Teams Breakout Converge Output Goal Copyright© 2010 Sally Elatta 13
  14. 14. Story Writing Workshops  Involve as many team members as possible.  Goal is to brainstorm and write as many user stories as possible under the themes identified. Leave the prioritization and evaluation for later.  Prepare the room with post-it notes, flip charts and markers.  Need an effective facilitator to run these meetings to keep folks on track. 14
  15. 15. Attributes of a User Story  A small piece of a requirement that is „valuable‟ to the product owner. U-INVEST Attributes: Understandable Story Format: Independent “As a <role>, I want to <goal>” Negotiable “Ability to <goal>” Valuable Estimatable Small Testable 15
  16. 16. Sample Stories As an Agent I As an Agent I want to view the want to add new ‘Current Leads’ lead information. report. As a BA I want to define the existing product return process. As the XYZ system As the EDW I want to receive System, I want to new member have ABC file enrollments each loaded on a night. schedule. 16
  17. 17. Requirements Breakdown • To breakdown Techniques • User Stories existing list of epics into small user stories. • Facilitator Led Workshop • All Stories should follow • Post-it Note U-INVEST. • Teams Breakout Converge Output Goal Copyright© 2010 Sally Elatta 17
  18. 18. Breaking Down the EPICS  Epics are large stories that need to broken down so they can be development-ready. They could be either Compound or Complex.  Compound means they have other independent stories within them.  Complex means that it is really one big independent story, but to get it done, we need to break it down to reduce it‟s complexity.  You break down epics during: Initial story brainstorming. During story sizing. During sprint execution when realizing scope is larger than anticipated. 18
  19. 19. Real World Methods for Story Break Down  We wanted to share some real world methods we‟ve used with various teams to break down Stories. Process Based Breakdown CRUD – Function Base Breakdown Business Rule Based Breakdown User/Platform Based Breakdown Copyright© 2010 Sally Elatta 19
  20. 20. Process Based Breakdown  Walk through the process steps it would take to get that Story completed. When done, investigate each step and ask yourself if this step could be an independent valuable testable story of it‟s own?  „As a student I want to register for a course‟ Browse View Register Login available course for courses details course Copyright© 2010 Sally Elatta 20
  21. 21. CRUD – Function Based Breakdown  Apply CRUD (create, read/search, update, delete)  Trigger words: Manage, Administer, Control, Setup, Configure  Example: „As a mobile user I want to manage my greetings‟ As a mobile user I want to create a default greeting. As a mobile user I want to modify my default greeting. As a mobile user I want to delete a greeting. Copyright© 2010 Sally Elatta 21
  22. 22. Business Rule Breakdown  Break down the business rules into simple/complex, positive/negative rules.  Start with the „simplest‟ story, then add complexity as you go.  Example: As a loan officer, I want to process a loan application: Process a simple loan application that is approved. Process a simple loan application that fails. Process a complex loan application that is approved. Process a complex loan application that fails. Copyright© 2010 Sally Elatta 22
  23. 23. User or Platform Based Breakdown  You can break down Stories based on the different user types (customer, agent, administrator) or different platforms it will be accessed via (mobile, portal, desktop) as long as additional work is needed to implement these.  Example: “As a phone user I want to listen to my voice mail”  As a mobile user I want to listen to my voice mail  As a portal web user I want to listen to my voice mail  As a desktop phone user I want to listen to my voice mail Copyright© 2010 Sally Elatta 23
  24. 24. Building a Release Plan  There are multiple steps to creating a release plan. Here is generally the most common activities: Build the backlog. Prioritize and size each story. Define what „Done‟ means for your team. Determine your iteration length. Estimate initial velocity. Map stories to iterations based on this estimate. Add fall-through, hardening, and pre-release iterations where needed. Arrive at initial delivery date estimate (for scope driven efforts) or Arrive at rough scope that could delivered by a specific date (for date driven projects). Copyright© 2010 Sally Elatta
  25. 25. Sample Team Definition of Done (Long!) 25
  26. 26. Planning for Additional Iterations  Fall-through iterations are needed after every 4 or 5 development ones. They are planned to be very light so they can be used to help complete any work that „fell through‟ from one iteration to the other.  Hardening or Quality iterations are added to do cross-team integration testing, regression testing, resolve any technical debt issues, do early alpha/beta testing ..etc.  A Pre-Release iteration is added before moving to production to prepare for this release for deployment. It includes user training, help doc finalization, acceptance and transition to support teams. Copyright© 2010 Sally Elatta

  29. 29. Story Deep-Dive (Details of a Story) • Identify detailed Techniques level requirements • Acceptance for each story. Tests • This should be • Facilitator Led • Business done a few weeks Workshop Rules before this Story • Teams • Test Examples will be Breakout • UI Prototype implemented. Converge • Activity Diagram Goal Output Copyright© 2010 Sally Elatta 29
  30. 30. Sample Acceptance Test Cases “A customer can pay for shopping cart items using a credit card” Test with VISA, MasterCard and American Express (pass) Test with Diner‟s Club (fail) Test with bad and missing 3 digit codes (fail) Test with expired cards (fail) Test with a purchase amount over the card limit (fail) 30
  31. 31. Test Examples
  32. 32. Business Rules  In some cases, the test itself contains the business rule itself. In other cases you will need to provide the list of business rules that apply to that test case.  1.1-TC1 „Verify that student eligibility rules are applied correctly during registration‟ TC1-BR1: Students with a „hold‟ record cannot register on the site. TC1-BR2: Students with outstanding payment from last semester cannot register. TC1-BR3: Student already registered cannot register again. 32

  34. 34. Managing Change  Rule #0: Identify Breadth then Break Stories Down! The more you focus on doing this right at the beginning the less “new scope” you‟ll have.  Rule #1: Assess the Impact When new requirements or changes are made, allow the team to assess and report the impact to the schedule. Don‟t just accept blindly.  Rule #2: Provide Options Let the Product Owner know they have options. Based on the impact, they are welcome to add but may need to also remove from the bottom of the list.  Rule #3: Product Owner Controls Scope Product Owner must control scope, not the Project Manager. They must be empowered to make decisions and clearly know schedule impacts and options. Copyright© 2010 Sally Elatta 34
  35. 35. Managing Change ..  Rule #4: Track the Changes! Don‟t just add and change requirements without tracking!  Rule #5: Deep-Dive Just in Time to Reduce Impact of Change Don‟t invest too much upfront on each requirement. Decide as late as possible, deliver as fast as possible!  Rule #6: Provide Stability Establish concrete rules for introducing new requirements. The team needs to focus during an iteration and should only address new scope in the following iteration. Copyright© 2010 Sally Elatta 35

  37. 37. 3 7 Summary  Addressing the challenges with requirements starts by designing a simple yet effective process.  We need to differentiate between the levels of requirements.  Using simple modeling and effective facilitation techniques can dramatically improve requirements gathering.  Release planning is a multi-step activity.
