CSC 715 Cheat Sheet

Intro & process

• SE = engineering of all aspects of software production (not just coding).
• Good software: maintainability, dependability/security, efficiency, acceptability.
• Generic (developer controls spec) vs bespoke (customer controls spec).
• Process activities: specification, design/implementation, validation, evolution.
• Models: waterfall (stable requirements); incremental (change); reuse-oriented (components exist).

Agile & requirements

• Agile values: individuals, working software, collaboration, responding to change.
• XP: user stories, CI, TDD, pair programming, refactoring.
• Scrum: Product Owner, Scrum Master, team; sprint planning/daily/review/retrospective.
• User req (high level) vs system req (detailed); functional vs non-functional.
• Elicitation: interviews, scenarios, use cases, ethnography.
• Validation: reviews, prototyping, test-case generation.

Modeling & architecture

• UML views: external (use case), interaction (sequence), structural (class), behavioral (state).
• 4+1: logical, process, development, physical, +scenarios.
• Patterns: MVC, layered. Pattern elements: name, problem, solution, consequences.
• NFRs drive architecture (performance, security, safety, availability, maintainability).

Testing & evolution

• Validation ("right product") vs defect ("product right").
• Stages: unit, component, system; then alpha, beta, acceptance.
• TDD: test first, then implement, then refactor.
• Maintenance: fault repair, environmental adaptation, functionality addition.
• Lehman: change, complexity, growth, quality. Legacy: scrap, leave, reengineer, replace.
