Extreme Programming (XP)
• Values – Communication – Simplicity – Feedback – Courage
• Programmer-centric • Customer prioritizes the project • Perform all
techniques/practices to the extreme
• Requirements Management – Short User Story – Note Cards
• Incremental • Small Releases • Simple Design • Automated Testing of
Everything • Collective Code Ownership • Team: Functions as a Whole • Not Deadline Centric • Pair Programming • Standardized Coding • Onsite Customer • Summary: Simplicity

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

Lean Software Development
• Reference: Toyota Manufacturing
• Loose Unwanted Pounds • Project Management
Framework • Focuses on Gathering the
"Right" requirements • Requirements are measured
on their impact to the Business • Customer plays an important
role by giving constant Feedback
• Based on TQM – Process is Important – People build and improve the
processes • Principles
– Eliminate Waste – Build Quality – Constant Feedback – Defer Delivery until complete – Deliver Fast – Team Empowerment – Keep focused by interacting
with other teams • Summary: Return on
Investment

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 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 24
Crystal
• Lightweight • Color coded to signify the size
& criticality of the methodology needed
• Projects – Small: Use Crystal Clear,
Yellow, Orange – Big: Use Sapphire, Diamond
(involves Human Risk) • If a Project Color changes,
characteristics of the new Color should be adopted
• Deliverables: Couple of Months
• Feedback: Continual
• Communication: Constant • Focus: Priorities based • Automated Testing &
Integration • Crystal Clear
– All members working in same room
– Minimal Documentation – Easy Accessibility – Project Safety by efficiency – Not life-critical – Team: 6-8 members – Team defines own standards
and guidelines • Summary: Size & Criticality
http://www.nainil.com/research 25
Dynamic Systems DevelopmentMethod (DSDM)
• Most popular methodology in UK • Approach for Current Business
Value • Phases
– Pre-Project – Lifecycle
• Feasibility • Business • Functional Model • Design & Build • Implementation
– Post-Project • Rules for Requirements
(MoSCoW) – MUST – SHOULD – COULD – WOULD
• Principles – Active User Involvement – Team has control – Frequent Delivery – Iterative & Incremental – All changes are reversible – Requirements are based on high
level info – Colloboration & Cooperation
• Mandate Testing throughout Lifecycle
• Team: 6 teams of 6 people each • Not recommended for Safety
Critical Systems (Nuclear Reactors, Life Support etc.)
• Summary: Current Business Value

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
