  • 2. Allan Kelly, BSc, MBA   Consulting, Training & Coaching for Agile adoption and deepening   Author:   Changing Software Development: Learning to be Agile, Wiley 2008. 33 Business Strategy Patterns for Software 97 Things Every Programmer Creators Should Know, Henney, 2010 Context Encapsulation in Pattern Languages of Program Design volume 5, 2006
  • 3. Agile   What is it?   and Lean? 3
  • 4. “Agile processes promise to react flexibly to What is Agility? changing requirements, Jim Highsmith, thus providing the 2002 “Agility is the ability to highest business value both create and to the customer at any respond to change in point in time” order to profit in a turbulent business environment.” Jutta Eckstein 2004   Today: Agile as Better   Respond to changing (business) environment   Faster, more productive, higher quality   Tomorrow: Agile creates new business models   Opportunities for those not confined by traditional IT4
  • 5. Agile   Its the business need, stupid 5
  • 6. Agile in context More prescriptive XP Scrum … Kanban Agile More Lean thinking philosophical: value, idea Organizational Learning based Applicability
  • 7. 1999-2004: Agile = XP   Extreme Programming   First Agile method to gain popularity   Developer centric practices and literature   Business need from onsite Customer   Customer on C3 was a Business Analyst   “Customer” view too simplistic   Short sighted   Assume customer knows   No discussion on how the customer knows 7
  • 8. 2005-today: Agile = Scrum   Scrum   Aproject management method without a project manager   Product Owner specifies need   Scrum silent on how the Product Owner knows 8
  • 9. Who is the Product Owner? Business Subject Analyst Matter /Domain Expert Product Manager 9
  • 10. Traditional approach Business Analysis / System Analysis Royce, 1968, “Managing the Development of Large Software Systems” 10
  • 11. 11
  • 12. BA/Product Owner Traditional approach Agile approach works ahead of team - scouting out requirements 6+ months   Slice through work Decide requirement Decide requirement   Everything in iteration   End-to-End Analysis / Design Analysis / Design   Deliver business functionality Code & Unit Test Code & Unit Test Merge & Release Merge & Release Iteration 1 (2 weeks) Iteration 2 (2 weeks)

  • 14. Close quarters requirements   Goals and objectives   replace Big Requirements Documents   under continual review   Requirements gathering is ongoing process   rather than only at the start   BA needs to stay involved   rather than leave after initial stages   Delivered functionality changes and evolves   in direction of the goal and objective   More to it than requirements gathering   Dialogue over document 14

  • 16. Less (software) is more Potentially 80% of software Only about 20% of development work is waste features & functions • Better requirements can reduce in typical custom demand by 80% software are used If 30+% of requirements change then We often encounter • Why bother doing work on them in requirements churn the first place? of 30% to 50% Solution: Mary & Tom Poppendieck Implementing Lean Software • Just In Time Requirements Development 2007 • Identify, implement, deliver in quick succession 16
  • 17. But....  There is a time and a place for everything  .... Requirements come second when changing to Agile 17
  • 18. The Alignment Trap IT Highly aligned ‘Alignment trap’ ‘IT Enabled growth’ Challenge 1: 11% companies 7% companies Doing the right thing • Get Agile •  IT spending +13% higher than average •  IT spending 6% less than average • From Maintenance to •  Sales -14% over 3 •  Sales growth +35% over Well-oiled years 3 years • Delivery focus ‘Maintenance zone’ ‘Well-oiled IT’ 74% companies 8% companies Challenge 2: •  Average IT spending •  IT spending 15% below • From Well-oiled •  Sales -2% over 3 average • To Growth years •  Sales growth +11% over • Requirements focus Less aligned 3 year IT Less Doing things right IT More Effective Effective Source: Shpilberg, Berez, Puryear, Shah: MIT Sloan Review, Fall 2007
  • 19. When adopting Agile Sequence the changes 1.  First Do it right   Management focus on the development team 2.  Do not emphasis requirements or BA role 3.  Get developers more effective Then 4.  Do the right thing   Focus on the what 5. Long term benefits in BA role 19
  • 20. Project constraints Product Resources Owner needs to Features (People) make these trade offs Fixed in the short run (Brooks Law) Scope creep Time (run backwards) Time boxed Agile projects negotiate over requirements rather than resources or time 20
  • 21. More work for Product Owners Less work for Project Managers •  Negotiate over feature delivery •  Self organizing teams •  Not when • No task allocation •  Flexible release plan Project • Tracking by delivery • Not Gantt chart Manager • Not % complete • Measure value delivered • Commitment over • Not time spent estimates •  Changing requirements • Not work packages BA/Product •  Sustainable pace Development • No whip cracking Owner team 21
  • 22. More work for Product Owners Less work for Project Managers •  Negotiate over feature delivery •  Self organizing teams -  Not when -  No task allocation •  Flexible release plan Project Manager •  Tracking by delivery -  No Gantt chart -  Not % complete •  Measure value delivered •  Commitment over -  Not time spent estimates •  Changing requirements BA/Product -  No work packages Development Owner •  Sustainable pace -  No whip cracking team 22
  • 23. More work for BA’s   More work for BA’s   More/better analysis can reduce work load in time   More responsible for value delivered   More conversations with Developers   Writing/Creating acceptance tests   Slack for Just in time requirements (Queuing theory)   Move from requirements push to needs pull   Therefore... 1 BA for every 3 to 7 developers   Stable product: 1 BA -> 7 developers   Rapid change: 1 BA -> 3 developers 23
  • 24. Take aways 1.  Being Agile means delivering business needs 2.  Product Owner is often a BA   Agile process does not remove need for needs 3.  BA take a back seat in early transition   Step forward as team becomes effective   Key in reducing work to be done 4.  Product Owner role is larger than BA role   Need greater staffing   Shift from Requirements Push to Need Pull 24
