  19. 19. Extreme Programming (XP) • Values • Incremental – Communication • Small Releases – Simplicity • Simple Design – Feedback • Automated Testing of – Courage Everything • Programmer-centric • Collective Code Ownership • Customer prioritizes the project • Team: Functions as a Whole • Perform all • Not Deadline Centric techniques/practices to the • Pair Programming extreme • Standardized Coding • Requirements Management • Onsite Customer – Short User Story • Summary: Simplicity – Note Cards http://www.nainil.com/research 19
  20. 20. Scrum • Reference: Scrum in Rugby (Restart the game after an accident) • Project Management Framework • Delivery of Software Iteration Provide Highest Business Value • 30-day iteration called Sprint • Members organize themselves • Team Size: 4-9 • Meeting Length: 10-15 minutes • Backlog – Product – Sprint – Release • Summary: Prioritized Business Value http://www.nainil.com/research 20
  21. 21. Lean Software Development • Reference: Toyota • Based on TQM Manufacturing – Process is Important • Loose Unwanted Pounds – People build and improve the processes • Project Management • Principles Framework – Eliminate Waste • Focuses on Gathering the quot;Rightquot; requirements – Build Quality – Constant Feedback • Requirements are measured on their impact to the Business – Defer Delivery until complete – Deliver Fast • Customer plays an important role by giving constant – Team Empowerment Feedback – Keep focused by interacting with other teams • Summary: Return on Investment http://www.nainil.com/research 21
  22. 22. Feature Driven Development (FDD) • Gather Domain Knowledge • Develop an Overall Model • Build a List of Features • Plan by Feature • Design by Feature • Build by Feature • Multiple Teams work parallel • Features can be combined into Feature Sets • Summary: Business Model http://www.nainil.com/research 22
  23. 23. Agile Unified Process (AUP) • Iterative & Incremental Framework • Risk Management • Testing for Quality Assurance • Assign Tasks • Version Control and Planning • Documentation is minimal and simple • Tools to accomplish the work are not defined • Process is Tailored to meet the requirements • Summary: Manage Risk http://www.nainil.com/research 23
  24. 24. Crystal • Lightweight • Communication: Constant • Color coded to signify the size • Focus: Priorities based & criticality of the methodology • Automated Testing & needed Integration • Projects • Crystal Clear – Small: Use Crystal Clear, – All members working in same Yellow, Orange room – Big: Use Sapphire, Diamond – Minimal Documentation (involves Human Risk) – Easy Accessibility • If a Project Color changes, – Project Safety by efficiency characteristics of the new – Not life-critical Color should be adopted – Team: 6-8 members • Deliverables: Couple of – Team defines own standards Months and guidelines • Feedback: Continual • Summary: Size & Criticality http://www.nainil.com/research 24
  25. 25. Dynamic Systems Development Method (DSDM) • Most popular methodology in UK • Principles – Active User Involvement • Approach for Current Business Value – Team has control – Frequent Delivery • Phases – Iterative & Incremental – Pre-Project – All changes are reversible – Lifecycle – Requirements are based on high • Feasibility level info • Business – Colloboration & Cooperation • Functional Model • Design & Build • Mandate Testing throughout • Implementation Lifecycle – Post-Project • Team: 6 teams of 6 people each • Rules for Requirements • Not recommended for Safety (MoSCoW) Critical Systems (Nuclear – MUST Reactors, Life Support etc.) – SHOULD • Summary: Current Business – COULD Value – WOULD http://www.nainil.com/research 25
  26. 26. Cowboy Coding • “Cowboy Coding” is often used as a pejorative (down grading) term by supporters of software development methodologies, such as Agile • Method: Not Defined (Self Governed) • Updates: Frequent Re-evaluation • Communication: Face-to-face • Documentation: Sparse http://www.nainil.com/research 26
