Common misread
All-modules stretch risk; close adapter contract first, then extend.
Direct DB and screen scrape are risky; wrappers need contracts and rate limits. This page states the phase-one documents, the owner and the acceptance metric. This page contrasts misreads vs safer cuts for «Wrapping Legacy Without APIs Without Digging a Pit».
Safer framing
Value is auditable boundaries and contract tests pass, not more menus.
- Align on «direct DB» before feature lists and quotes.
- Phase one ships an acceptable loop: adapter contract.
- Name master-data and permission owners in contract to avoid fragile scrape.
- Dual-run deltas go to change control—not verbal rewrite legacy first.
- DaXi Technology boundary: contract tests pass; no hollow module piles.
| Decision lens | Common trap or cost | Safer cut |
|---|---|---|
| direct DB | Scope drift | Freeze phase one: adapter contract |
| fragile scrape | Rework/blame | Owners+change orders |
| rewrite legacy first | Post-go-live rollback | Accept: contract tests pass |
Why not all modules for direct DB?
All-modules stretch risk; close adapter contract first, then extend.
Why custom vs SaaS/package?
Value is auditable boundaries and contract tests pass, not more menus.
How to estimate time/budget?
By transaction-chain effort for adapter contract; change windows priced apart.
How does DaXi Technology accept?
Replay real work for adapter contract; metrics in contract—not «feels ok».
