Objective
Study how to model workflow-heavy features so state transitions stay predictable, auditable, and safe under real production usage.
Why This Matters
Many business products are really workflow systems underneath.
Examples include:
When transitions are not modeled clearly, systems become hard to debug and easy to misuse.
Core Idea
A workflow should define:
This creates a more reliable system than letting records jump between statuses loosely.
Design Considerations
Explicit Transition Rules
Do not allow any state to move to any other state.
Instead, define valid moves such as:
This reduces invalid states and makes backend logic easier to reason about.
Side Effects and Approval Logic
A transition may also trigger side effects:
These should be treated as part of workflow design, not afterthoughts.
Failure Modes
Workflow systems often fail because:
Project Relevance
This topic maps directly to ATS stage progression, expense approvals, performance review cycles, and payroll-related operational flows in your portfolio.
Practical Rule
If a feature has statuses, approvals, or business handoffs, model it as a workflow intentionally instead of letting status fields drift into ad hoc logic.
