Enterprise Software Development Framework

1. High-Level Organizational Structure

Large-scale engineering requires a Matrix Organization combined with Cross-Functional Squads. This ensures both deep technical expertise and fast feature delivery.

The Squad Model (Execution)

A "Squad" is a self-contained mini-startup of 6–10 people.

• Product Owner (PO): Owns the "Why" and "What." Manages the roadmap.
• Engineering Manager (EM): Owns the "Who." Focuses on people, hiring, and growth.
• Software Architect: Owns the "How." Focuses on system design and scalability.
• QA Engineer / SDET: Owns the "Quality." Responsible for:
  • Writing and maintaining test plans, test cases, and acceptance criteria.
  • Shift-left testing: reviewing stories for testability during grooming.
  • Automated regression suites (unit, integration, E2E).
  • Exploratory / manual testing for UX and edge cases.
  • Sign-off on the Quality Gate before merge.
  • Bug triage and defect tracking.
• Developers: 3-5 Backend, 2 Frontend.
• DevOps / SRE: 1. Owns infrastructure, CI/CD pipelines, and site reliability.
