- small, frequent releases
Scrum process
agile methodology focused on iterative work cycles (sprints)
Key scrum elements
- Product backlog
- list of features - Sprint
- fixed-time development
cycle. - daily Scrum meetings
- 15 minute check ins - Scrum master
- facilitates meetings - Sprint review and demo
- Presenting completed
features. - Sprint retrospective
- reflecting on
improvements
Advantages of Scrum
- team collaboration
- opportunities for corrections
- Usable software at end of each sprint
Dynamic systems development method (DSDM)
agile framework on business value
DSDM core phases
- Feasibility check
- is the project viable?
- Prototype and feedback
- create/ test early models
- Refine and Build
- improve software
iteratively
- improve software
- Deploy
- release software
DSDM Key principles
*Focus on business needs
*Deliver on time
*Collaborate
*Quality/ iterative progress
Scaling Agile methodologies
Challenges of scaling agile
*Better for small teams
*Less documentation
*New projects over maintenance
Scaling Agile methodologies
Approaches to Scaling
