00 / Engagement
How an engagement runs. Week by week.
Discovery is free. Once we sign, scoping starts within 48 hours. Production cutover lands inside two to ten weeks depending on tier. This is what happens between those two dates.

How tiers and edge cases shift the timeline.
- NOTE / 01
Starter tier compresses Weeks 1 to 4 into a single sprint. Same milestones, faster cadence, fewer edge cases.
- NOTE / 02
Complex tier extends Build to Weeks 2 to 6 and adds a second UAT pass. Cutover lands Week 7 to 10 depending on testing surface.
- NOTE / 03
We do not stack engagements. While we are building yours, you are our only build. Discovery and retainer work continue in parallel for other clients.
- NOTE / 04
Cutovers are scheduled Tuesday through Thursday. Never Friday, never the week of a public holiday.
03 / NEXT MOVE
