Product Road Map
Definition
A product road map is a time-phased plan showing when products will be introduced, enhanced, and retired, giving supply chain teams the forward visibility needed to plan capacity, sourcing, and inventory around lifecycle transitions.
In Practice
For planners, the road map is an early-warning system. A launch two quarters out drives supplier qualification, long-lead component orders, and capacity reservations today; a planned end-of-life drives inventory run-down so the last builds finish just as demand ends, avoiding write-offs. Phase-in/phase-out planning links the old and new products so the ramp-down of one funds the ramp-up of the other.
Road map changes are a top cause of excess and obsolete inventory: a slipped launch strands transition stock, and an accelerated one creates shortages. Mature S&OP processes therefore review the road map alongside the demand plan, so supply commitments track the current lifecycle plan rather than the one from last quarter.
Frequently Asked Questions
Why does the supply chain team need the product road map?
Because supply decisions lead demand by months: supplier qualification, tooling, long-lead components, and capacity must be committed well before launch, and end-of-life inventory must be run down before demand stops. Without road map visibility, launches slip on material and retirements end in obsolete stock write-offs.
What is phase-in/phase-out planning?
It is the coordinated management of a product transition: the replacement's ramp-up schedule is linked to the outgoing product's ramp-down, so shared capacity shifts smoothly and the old item's inventory reaches zero as its demand ends. Planning both together prevents simultaneous shortage of the new and excess of the old.
