Strategic partnership investment: 90-day implementation playbook

Executive summary

A method for running the first 90 days of a live partnership so service levels, contribution, and trust are established on evidence both partners share.

What is inside

What the 90-day playbook covers

The asset walks two alliance managers through three 30-day blocks after go-live: launch the hand-offs, ramp and prepare the contribution gate, and stabilize. It covers workstreams, milestones, the weekly rhythm, the shared issue log, escalation, and the checkpoint scorecard, with a worked synthetic case.

Turning an agreed partnership operating model into live joint work
What must be true on go-live day
Running each hand-off at its service level from the first week
Reading partner contribution above the pre-partnership baseline
The weekly rhythm between the two alliance managers
Logging and resolving issues before they become disputes
Checkpoints at day 30, 60, and 90 that prepare the contribution gate

How to use it

How teams use it

Teams use it from the go-live gate. Both alliance managers run it together, function owners report hand-off performance weekly, and both sponsors review the checkpoints. Communities of practice rehearse go-live week with both partners in the room.
