This document provides an introduction to agile development methods. It discusses that agile methods are designed to deal with frequent changes by emphasizing individuals, interactions, working software, and responding to change. The core of agile development involves planning in terms of user stories, working in short iterations to deliver working functionality, prioritizing stories, calculating team capacity, and negotiating scope with customers based on feedback from iterations. Specific agile practices mentioned include test-first development, pair programming, and refactoring. The document also advertises agile training courses on nuts and bolts agile concepts and an introductory crawl before you leap course.

- 5. Industrial Making “ The stated, accepted philosophy for systems development is that the development process is a well understood approach that can be planned, estimated, and successfully completed. This has proven incorrect in practice.” - Ken Schwaber Big Design Up-Front
- 6. “ Writing software is a creative process, like painting or writing or architecture” “ Categorizing the systems development methods as empirical is critical to the effective management of the systems development process.” - Ken Schwaber Empirical and Artistic Making
- 7. Agile Manifesto Individuals and interactions over processes and tools Working software over comprehensive documentation Customer collaboration over contract negotiation Responding to change over following a plan
- 8. Agile Development Process Plan in terms of Stories Work in Short Iterations Prioritise your stories Calculate your capacity Negotiate in Terms of Scope Get customer feedback
- 9. Plan in Terms of Stories Stories are short descriptions of customer-visible functionality
- 10. Generate Stories Book a hotel Purchase ticket Review itineraries Show hotel availability Find lowest fare Cancel itinerary Show hotels Offer sophisticated hotel search Do simple customer profile Show available flights Sort available flights by convenience Stories for a travel website
- 11. Estimate Effort for Stories Show available flights - 2 Show hotels - 3 Show hotel availability - 2 Book a hotel - 1 Purchase ticket - 2 Review itineraries - 2 Find lowest fare - 3 Cancel itinerary - 2 Offer sophisticated hotel search - 3 Do simple customer profile - 2 Sort available flights by convenience - 3
- 12. Prioritise Stories Show available flights - 2 -*** Show hotels - 3 -*** Show hotel availability - 2-*** Book a hotel - 1-** Purchase ticket - 2-** Review itineraries - 2-** Find lowest fare - 3-** Cancel itinerary - 2 -** Offer sophisticated hotel search - 3 - * Do simple customer profile - 2 - * Sort available flights by convenience - 3 -*
- 13. Work in Short Iterations
- 14.

- 15. ? ? Know your capacity
- 16. Calculate your capacity and velocity Show available flights: estimated 2 - actual 3 Show hotels: estimated 3 - actual 5 Show hotel availability: estimated 2 - actual 3 Book a hotel: estimated 1 Purchase ticket: estimated 2 Team Capacity is: 2+3+2 = 7 points per week Team Velocity is: 7 = 0.64 11
- 17. Plan your next iteration
- 18. Get Feedback - Demo the iteration Show available flights Show hotels Show hotel availability
- 19. Get Feedback - Prioritise Stories Book a hotel - 1-** Purchase ticket - 2-** Review itineraries - 2-** Find lowest fare - 3-** Cancel itinerary - 2 -** Offer sophisticated hotel search - 3 - * Do simple customer profile - 2 - * Sort available flights by convenience - 3 -* Deal with change Show images of hotel rooms - 2 - *** Iteration 2
- 20. What happens when the time/money runs out?
- 21. Negotiate in terms of scope “ Write contracts for software development that fix time costs and quality but call for an ongoing negotiation of the precise scope” Kent Beck, Extreme Programming Not Quality
- 24. Test First
- 25. Pair Programming
- 26. Refactoring
