To build a large-scale, "Platform-Grade" application, we move beyond "coding features" to "engineering systems". We follow a 5-Phase Planning Lifecycle.
🏗️ Phase 1: Discovery & User Journeys (The "Why" & "What")
Goal: Understand the human problem before solving the technical one.
- Artifact:
user_journey.md - Focus: Stories, Personas, Workflows.
- Key Question: "What is Ayva trying to achieve, and how does it feel?"
- Status: ✅ We are doing this well.
🏛️ Phase 2: Architecture Decision Records (ADR) (The "Strategy")
Goal: Make high-level technical choices that affect the whole system.
- Artifact:
architecture/{topic}_redesign.md - Focus: Trade-offs (e.g., "Multi-Tenant vs Single Tenant", "SQL vs NoSQL").
- Key Question: "How do we structure this so it doesn't collapse under 100k users?"
- Status: ✅ We are doing this well.
🧩 Phase 3: Domain Modeling (The "Business Logic")
Goal: Define the "Truth" of the system independent of the database or UI.
- Artifact:
domain_model.md - Focus: Entities, Attributes, Relationships, State Machines.
- Key Question: "What is a 'Member'? Can a 'Member' exist without a 'Tenant'? What are the valid states of an 'Invite'?"
- Missing Step: We currently jump from User Journey -> DB Schema. We need this middle step to catch logic bugs early.
🔌 Phase 4: Interface Design (The "Contract")
Goal: Define how systems talk to each other before writing code.
- Artifact:
api_spec.md(or OpenAPI/Swagger) - Focus: REST endpoints, Request/Response bodies, Error codes.
- Key Question: "Frontend needs to send X to Backend. Does Backend actually need X?"
- Missing Step: Prevents "Frontend waiting for Backend" blocks.
💻 Phase 5: Implementation (The "How")
Goal: Write the code that fulfills the artifacts above.
- Artifact:
implementation_plan.md(Checklist), Code. - Focus: File changes, functions, tests.
- Key Question: "Does this code match the design?"
Recommended Next Step
To level up our planning, we should implement Phase 3 (Domain Modeling) for the Team Management feature we just designed. This will reveal edge cases we missed in the User Journey.
