Scope one problem with a measurable result, give the engineer system access and real users in week one, ship a thin slice to production early, then expand. Agree on hand-over from day one so your team can run what gets built.

Before day one
- Write the problem in one sentence and pick the number that proves it's solved.
- Name an internal owner who can make decisions within a day.
- Pre-approve access: repos, environments, data, and the users to interview.
A 30-day shape
| Week | Focus | Output |
|---|---|---|
| 1 | Discovery — on-site if useful — and environment setup | Problem map and a thin-slice plan |
| 2 | Build the thin slice | Something real in a test environment |
| 3 | Ship to a small group of users | First production use and feedback |
| 4 | Harden and expand | Monitoring, docs, next-slice plan |
Common failure modes
- No owner — Decisions stall; the engineer builds the wrong thing.
- Access delays — Two weeks lost waiting for credentials.
- Demo-only success — It works in a sandbox but never meets real users.
- No hand-over plan — Nobody can maintain it after launch.

Common questions
How long should an FDE engagement last?
As long as the problem needs. NextGen has no minimum engagement, so start with one problem and extend only if it's paying off.
Does the engineer need to be on-site?
Not always. On-site time is most valuable in week one and during rollouts; our US-based engineers travel when it helps.
Have a specific situation? Talk to an engineer at NextGen — we do free 30-minute scoping calls with a senior developer, not a salesperson.
