Software development lifecycle support in agile methods Crystal DSDM XP FDD Agile RUP Scrum Concept Creation Requirements Specification DesignCodeUnit testIntegration test System test Acceptance test System in use Adapted from Abrahamsson, P., Salo, O., Ronkainen, J., & Warsta, J. (2002). Agile Software Development Methods: Review and Analysis. VTT Publications 478. (pp. 95) KEY: Project management Process Practices / activities / work products

Agile Microsoft Solutions Framework Foundational Principles Foster open communications Work toward a shared vision Empower team members Establish clear accountability and shared responsibility Focus on delivering business value Stay agile, expect change Invest in quality Learn from all experiences

Agile UP Phases Inception, Elaboration, Construction, Transition Disciplines Model, Implementation, Test, Deployment, Configuration Management, Project Management, Environment Philosophies Your staff knows what they're doing, Simplicity, Agility, Focus on high-value activities, Tool independence, You'll want to tailor the AUP to meet your own needs

Crystal Clear Frequent Delivery of Usable Code to Users (required) Reflective Improvement (required) Osmotic Communication Preferably by Being Co- Located (required) Personal Safety Focus Easy Access to Expert Users Automated Tests, Configuration Management, and Frequent Integration

DSDM Principles User involvement is the main key, The project team must be empowered, Frequent delivery of products, Delivering a system that addresses the current business needs, Development is iterative and incremental, Changes are reversible, High level scope and requirements should be base-lined, Testing is carried out throughout the project life-cycle, Communication and cooperation among all project stakeholders Techniques Timeboxing, MoSCoW, Prototyping, Testing, Workshop, Modelling

eXtreme Programming (XP) Values Communication, Simplicity, Feedback, Courage, Respect Activities Coding, Testing, Listening, Designing Practices Pair programming, Planning Game, Test Driven Development, Whole team, Continuous Integration, Design Improvement, Small Releases, Coding Standards, Collective Code Ownership, Simple Design, System Metaphor, Sustainable Pace

Feature Driven Development Activities Develop Overall Model, Build Feature List, Plan By Feature, Design By Feature, Build By Feature, Milestones Best practices Domain Object Modeling Developing by Feature Individual Class (Code) Ownership Feature Teams Inspections Configuration Management Regular Builds Visibility of progress and results

Scrum Techniques Team creation Backlog creation Project segmentation Scrum meetings Burndown charts Phases Review release plans Distribution, review and adjustment of product standards Sprint Sprint review Closure
