Most AI implementation roadmaps are vague. They list "adopt AI" as a milestone. This is a concrete 90-day template — week by week, owner by owner, deliverable by deliverable — built from the rollouts we have run at B2B companies between $5M and $50M.
This template is opinionated. It assumes a B2B team of 10–50 people, a CEO or COO sponsor, and at least one operations person who can own the work. If you are bigger or more regulated, the timeline stretches; if you are smaller and faster, it compresses.
Three rules before you start. (1) Pick one revenue function and one operations function — do not try to roll AI out everywhere. (2) Name a single human owner per workflow you change — no committees. (3) Define what "shipped" looks like for each phase before you start that phase.
A 90-day roadmap fails the same way every time: leaders treat it as a slide deck instead of a calendar. Put every milestone in a real calendar with a named owner and a checkpoint date. Half of execution is just making the schedule visible.
If you have not shipped any of your top 3 workflows by end of week 8, stop adding workflows. Diagnose why the first one stalled. Usually the answer is no named owner or no time carved out — both fixable, neither solved by adding scope.
Workflows that touch regulated data (HIPAA, SOC 2, financial advice) require an additional 30-45 days of compliance work. Add that to the front of the timeline if you are in those industries.
Enterprise rollouts (200+ people) need a different model — federated by function with a small central enablement team. This template is for teams under 100.
If you have never deployed software internally before, the change-management work is bigger than the AI work. Plan for that explicitly.
