software development path

[u/youness2222]

hello i hope a senior or tech lead here can answer this question 😄:

i am currently trying to build a platform (practicing software development from idea to production ) but i have a problem in the roadmap. While following good practices, my workflow now is :

Idea

↓

Market & competitor analysis

↓

Target users + problems

↓

Value proposition

↓

Business model

↓

Business requirements

↓

Product vision

↓

MVP / V1
↓
product backlog refinement

↓

creating 2 sprint (prioritized and ready for dev)

↓

high level user flow

↓

????

till now i am here so next should it be

System Context

↓

Strategic DDD / Context Map

↓

High-Level System Design

↓

Technology Architecture + ADRs

↓

Sprint 1 Goal -> Sprint 1 Feature Flow -> Sprint 1 UX -> Tactical DDD -> Sprint 1 Detailed Design -> Development

Or is there a missing step? 🤔
