This paper presents a process to develop members of a component-based product line for Workflow Management Systems (WfMS). A specific application can be developed from this infrastructure by customizing its variable aspects. It offers both technical and managerial support to design applications for a specific domain from a well-defined infrastructure. The product line approach has been pointed out as a means to improve software organization's productivity. The results have shown that the proposed process has made explicit a higher number of variabilities than does the existing PL process, and it offers better support for variability tracing. The case study was carried out based on the experimental software engineering concepts. The process is illustrated with excerpts of a case study carried out within the context of an existing PL for the Workflow Management System (WfMS) domain. This paper presents a UML-based process for variability management that allows identification, representation and delimitation of variabilities as well as identification of mechanisms for variability implementation. Variability management is concerned with the management of the differences between products throughout the PL lifecycle.

This approach is applicable to domains in which products have well-defined commonalities and variation points. The software product line approach (PL) promotes the generation of specific products from a set of core assets for a given domain.
