Study Notes

Phases of RUP (Rational Unified Process)

Inception: Establishes vision document and business case; identifies high-level requirements and risks to achieve stakeholder consensus.
Elaboration: Develops 80% complete use case models; creates prototypes to explore key risks, leading to a solid development plan and architecture description.
Construction: Produces demonstrable prototypes and working software components; focuses on coding as the core activity.
Transition: Involves training for end users and maintainers, evaluates project against Inception requirements, and conducts post-mortem analysis.

Advantages and Disadvantages of RUP

Advantages:
- Iterative support contrasts with classic waterfall model.
- Encourages continuous integration throughout software development.
- Testing can commence early, ensuring issues are identified sooner.
Disadvantages:
- Complexity leads to significant process overhead, consuming more resources for management rather than purely development.

RUP vs Agile

Flexibility: Agile is highly flexible, promoting customer collaboration and rapid iteration; RUP maintains structure and rigidity.
Iterative Structure: RUP uses defined iterations but is more prescriptive; Agile facilitates ongoing feedback and adaptation.

Agile Principles

Organisational: Puts the customer first and allows self-organization; promotes sustainable work pace and minimal software production while accepting changes.
Technical: Iterative development prioritizes frequent working iterations with a focus on passing tests before new developments.

Key Characteristics of Agile

Emphasizes frequent delivery of working software as the primary measure of progress.
Allows for late changes in requirements without significant issues.
Encourages close daily cooperation among all team members.
Uses visual tools like Kanban boards to manage work-in-progress (WIP) and track team capacity.

Extreme Programming (XP)

Advocates early coding and release combined with continuous design.
Pair Programming: Two developers work collaboratively, enhancing quality and facilitating immediate feedback.
Test-Driven Development (TDD): Tests are written prior to coding, ensuring development aligns with testing criteria.

Four Principles of XP

Core Activity: Programming not only provides solutions but also aids problem exploration.
Testing: Heavy emphasis on continuous testing during development.
Direct Communication: Developers work closely with customers to ensure understanding of business requirements.
Kanban Boards: Visual tools for tracking WIP and team capacity.

Scrum Framework

Lightweight iterative process structured in 2-4 week sprints for collaboration and continuous improvement.
Product Backlog: Prioritized list of features that deliver customer value, estimated in effort required, maintained by the Product Owner.
Scrum Team Roles:
- Developers: Responsible for design, coding, testing, and integration.
- Scrum Master: Facilitates team meetings and resolves blockers.
- Product Owner: Manages the product backlog and collaborates with stakeholders.

Sprint Backlog

Lists user stories to be completed in the current sprint; stories are frozen to maintain focus.
Tasks associated with user stories visualized on a scrum task board and monitored by the Scrum Master for progress.

Scrum vs Kanban

User stories provide a non-technical contextual framework and prioritize customer needs.
Acceptance criteria are defined to establish completion benchmarks for user stories with varying detail (checklist-based or scenario-based).

Characteristics of Good User Stories (INVEST)

Independent: Each user story should stand alone for ease of estimation and inclusion in sprints.
Negotiable: Open to discussion and refinement until sprint starts.
Valuable: Should provide clear value from the perspective of the end user.
Estimable: Clear enough for developers to estimate effort.
Small: Sized appropriately to fit within a sprint, avoiding complexity.
Testable: Must have clear criteria for success to enable testing.

Epics in Agile

Large stories representing significant functionality, serving as placeholders in the product backlog.
Epics help organize user stories; they can be broken down into smaller stories for detailed management.
