Use the whole Method or a sufficient part
Start with the supported offering and the actual customer result. Recover their consequential differences, then construct a compatible local and shared continuation. Productization can produce a repeatable service or reusable contribution; it does not require every local adaptation to become a common product.
The intended reader manages a product, service, customer delivery, implementation practice or another undertaking with continuing customer commitments. Use the large CUST.1 Method when the customer case and future offering must be developed together. Use a smaller Method when the current problem is already bounded. A supported configuration needs no new productization programme.
Read the Architectural Reference for the field, connections and limits. Using FPF and its DPF Suites explains how to obtain supplying frameworks. Reading a Method supplies neither its required professional capabilities nor permission to perform restricted work.
