Software Engineering (SE) Cheat Sheet

This document summarizes essential concepts in Software Engineering, including SDLC, Agile, Scrum, and CI/CD.

Software Development Life Cycle (SDLC)

SDLC is a process for creating high-quality software, consisting of core phases:

• Requirement Analysis: Gathering and analyzing requirements from stakeholders.
• Design: Designing system architecture and software design.
• Implementation (Coding): Writing code according to design specifications.
• Testing: Testing software to find bugs and verify it meets requirements.
• Deployment: Installing software into a production environment.
• Maintenance: Maintaining and fixing bugs, as well as updating new features.

Agile Methodology

Agile is a software development approach that focuses on iterative and incremental work.

• Focuses on collaboration within the team and with stakeholders.
• Responds quickly to changing requirements.
• Delivers working software frequently.

Scrum Framework

Scrum is a framework under Agile for managing complex projects.

• Roles: Product Owner, Scrum Master, Developers
• Artifacts: Product Backlog, Sprint Backlog, Increment
• Events: Sprint, Sprint Planning, Daily Scrum, Sprint Review, Sprint Retrospective

Continuous Integration / Continuous Deployment (CI/CD)

CI/CD is a practice for automating the software release process.

• Continuous Integration (CI): Frequently merging code from multiple developers into a shared repository, along with running automated tests.
• Continuous Delivery (CD): Always keeping code in a ready-to-deploy state for production.
• Continuous Deployment (CD): Automatically deploying code to a production environment when all tests pass.
