Key Roles: Product Owner, Scrum Master, Development Team
Scrum features three key roles:
- Product Owner: Handles the product backlog, prioritizing tasks to maximize value.
- Scrum Master: Ensures the team follows Scrum practices, removes impediments.
- Development Team: Cross-functional members who build the product.
Scrum Artifacts: Product Backlog, Sprint Backlog, Increment
- Product Backlog: Comprehensive list of features, enhancements, and fixes prioritized by the Product Owner.
- Sprint Backlog: Subset of the Product Backlog items the team commits to completing in a sprint.
- Increment: The working product at the end of a sprint, ready for use and potentially shippable.
The Sprint Cycle and Sprint Planning
Sprints are time-boxed to usually two to four weeks.
Each sprint starts with Sprint Planning, where the team selects tasks from the Sprint Backlog. Daily Standups help keep progress on track. Sprints conclude with a review and retrospective for continuous improvement.
Kanban
Kanban helps visualize tasks through board systems like Trello.
Each task moves through columns representing different workflow stages, from ‘To Do’ to ‘Done.’
Limiting Work in Progress (WIP)
By setting limits on WIP, Kanban aims to avoid bottlenecks.
This ensures a smooth flow and that work is completed before starting new tasks.
Continuous Delivery and Improvement
Kanban doesn’t have set iterations. It’s about continuous delivery.
Tasks move through the workflow as they’re completed, with constant refinement for efficiency.
Extreme Programming (XP)
Extreme Programming (XP) emphasizes technical excellence and customer satisfaction through best engineering practices.
Frequent Releases in Short Development Cycles
XP involves frequent releases every few weeks. This ensures that any adjustments can be made quickly in response to feedback.
Pair Programming, Test-Driven Development, and Continuous Integration
- Pair Programming: Two developers work together at one workstation.
- Test-Driven Development (TDD): Writing tests for functionality before writing code.
- Continuous Integration (CI): Regularly merging code changes to detect integration issues early.
Lean Software Development
Lean focuses on eliminating waste—anything that doesn’t add value—and amplifying learning to continually improve processes.
Delivering Fast by Empowering the Team
Lean principles strive for speed by empowering teams to make decisions, reducing delays, and enhancing efficiency and productivity.
Adaptive Project Framework (APF)
APF is ideal when initial project requirements are unclear. It allows for flexibility and adapting as more information becomes available.
