​​Mosky’s Extended-SDLC
​​It’s an extended version of the systems development life cycle (SDLC) which aims to provide a framework for a project owner or an engineer to plan—especially estimating the ETA or the ETAs of milestones (schedule)—a project more firmly.
​​
​​Phase
​​Notes
​​Hibernation
​​
​​Unstarted
​​
​​Planning
​​Plan the project, e.g., goal, people, time; estimate the ETA-to-design.
​​Analysis
​​Clarify the to-be, and prospect the as-is by to-be.
​​Design
​​Design how to fill the gap between as-is and to-be, including system design reviews; estimate the ETA-to-release.
​​Implementation
​​Implement the system, including unit tests.
​​Integration
​​Including module-module, server-client, integration tests like API tests.
​​Translation
​​
​​Review
​​Including code reviews, (internal) user reviews, and adjusting after reviews.
​​Testing
​​Including making a test plan, writing complex tests like E2E tests, performing manual tests, and fixing after tests.
​​Release
​​You may need a migration before the release.
​​Maintenance
​​Handle issues; estimate the ETA-to-close.
​​Closed
​​May still follow the metrics.

​​Extended-SDLC & Scrum
​​
​​SDLC's planning, analysis, ..., review are different from Scrum's planning and review. For example, in the SDLC's review phase, we may schedule an issue fix in a Scrum's planning meeting, and then an engineer may fix and demonstrate in the next Scrum's review meeting.

​​Extended-SDLC & Triple Diamond

​​
​​This is paired with two types of thinking:
​​
  • ​​Divergent thinking – where lots of ideas are created
  • ​​Convergent thinking – where ideas are narrowed and refined into the best idea
​​
​​The double diamond and the SDLC can be linked as the triple diamond:
​​
  • ​​1st diamond: Planning–Analysis
  • ​​2nd diamond: Design–Release
  • ​​3rd diamond: Maintenance–Closed
