Where you are

You have priorities, an architecture, technology choices, a risk register and a delivery approach. Now you turn them into a roadmap the business can fund, and defend the whole pack to a sceptical review board, the way a CTO would to investors or a board.

What you will make

A phased roadmap: what each phase delivers, which risk it reduces and roughly what it costs. Two or three architecture decision records: decision, reason, alternatives, consequences and the trigger to revisit. And the review board's feedback, with what you will change.

For TutorDesk: phase 1 (months 1–2) accounts, bookings, payments and backups, with a penetration test and data protection review before launch; phase 2 (3–4) calendar sync, reminders and monitoring; phase 3 (5–6) reporting and scale tests. Decision record: modular monolith, not microservices, because a team of three can't run many services; revisit at three or more teams.
