  1. Lean Software Management:BBC Worldwide Case Study Dr Peter Middleton MBA PeterJonMiddleton@gmail.com 13th June 2014 IASA Ireland, Dublin Irish Computer Society

  2. IASA • Business Technology Strategy • IT Environment • Quality Attributes • Design • Human Dynamics

  3. Volume + Constant change • Requirements / Budgets / Business • Sponsors • Users • Hardware / Networks • Database • Software • Staff skills and availability • Culture / Privacy / Legal / Learning

  4. UK Government advice PRINCE2: ‘Ensuring that the information required for the project team is available.’

  5. BBC WorldwideDigital Hub Software Team • WaterfallAgileLean • London • 9 staff: Analyst, Architect, QA, Developers • Operating cost: £1.5m p.a. • C#, .NET, MS SQL Server • RISK

  6. Lean Software – key ideas • Reduce Work in Process: • Minimum Marketable Feature • Analysis / Specifications • Design • Untested code • Reduce total end to end time • Visible management & less risk • Flexibility

  7. BBC

  8. Lead time to customers -37%Variance -47%

  9. Throughput:smaller, incremental deliveries

  10. Fewer Bugs: -24%; Variance: -33%

  11. Possible problems • Space needed for Kanban & info boards • Plan driven, document centric process • Poor fit with standardised reporting • Remit of IT – upstream & downstream • Command & control compliance model • Staff initiative and multi skilling Lean handles risk by low WIP, transparency, small units & frequent deliverables

  12. Conclusion • Lean provides discipline and agility • Software under quantitative control • Frequent, small, high value deliverables • Experiments to demonstrate: • End to end time measure • Work in Progress – white board & post notes Lean Software Management: BBC Worldwide Case Study, P. Middleton & D. Joyce, IEEE Trans. on Engineering Management

  13. Continual ImprovementDays lost: -81% 26 to 5 days

  14. Development Time -73%; Variation -78%

  15. Differences Agile and Lean • Batch / Push versus Pull • Time-boxed iterations • Reliance on Data • Focus on people • Continual Improvement • ‘impediment list’ / ‘improvement backlog’‘ • Multi skilling • Velocity’, features, story points

  16. Engineering Practices • Decoupling – improve legacy code • Test Driven Development (unit tests) • Automated Acceptance Testing • Source Control Software • Bug tracking software • Daily Stand Up (15 minutes)

  17. Follow up • to the IEEE article http://leanandkanban.wordpress.com/2011/04/09/lean-software-management-bbc-worldwide-case-study/ • http://leankitkanban.com/ (lean tool) • peterjonmiddleton@gmail.com • dpjoyce@googlemail.com • Twitter: @dpjoyce
