Product portfolio rationalization: 90-day implementation playbook

Executive summary

A 90-day playbook that converts an approved product portfolio rationalization case into executed first-wave retirements with protected revenue transfer.

What is inside

What the playbook covers

The asset takes the approved investment case, operating model and roadmap and walks the implementation team through mobilization, per-product clearance, customer notice and migration, end-of-sale execution, inventory run-down, and the weekly action and escalation rhythm, ending at a day-90 gate that decides wave 2.

Scope: the first 90 days after the rationalization case and operating model are approved
Mobilization: freezing the wave scope and chartering six workstreams with named owners
A milestone plan built backward from end-of-sale dates, with a day-30 readiness gate
Customer notice and migration execution, with coverage rules by customer type
Inventory run-down, last-time-buy handling and order-intake cutover
A weekly action log rhythm with time-boxed escalation rules
Day-60 and day-90 measurement gates that decide whether wave 2 proceeds

How to use it

How teams use it

Teams open it the week the investment case is approved, rehearse the first 30 days in an implementation workshop before day 1, run the weekly rhythm from the included tools, and bring the day-90 gate pack to the portfolio council as the trigger for wave 2.
