Software Product Lines (SPL) are a well known solution to systematically create reusable software products. Amongst the approaches to create SPL, the extractive approach is usually used when the organization already has a set of similar systems. These systems are analyzed to extract, categorize and group their common and variant features throughout the SPL re-engineering process. As there are different scenario variables, such as, available artifacts and team experience, the activities and techniques used to perform these tasks may change. This may increase the effort and decrease the precision of the retrieved features when users with low experience in SPL re-engineering perform such tasks. However, there is not a process support performing these tasks considering different scenarios. With the objective of creating a process to be applicable in difference scenarios and flexible to fulfill the users needs, we sought in the literature and analyzed SPL re-engineering processes. We collected information about these process and compiled them to create our own. Therefore, we propose PAxSPL, a process that provides support to prepare, assemble and execute feature retrieval throughout the analysis of product artifacts, documentation and team experiences. Within PAxSPL we also included a set of guidelines to give support to those who may perform it. To evaluate our proposal contribution to the SPL field, we applied a survey in experts of the area. The survey results gave use evidence about PAxSPL contribution and relevance for the field. To further evaluate our process we conducted and reported an exploratory case study in a real development environment. The organization where the case study was executed possesses a large number of products that are candidates to become SPL. The case study results were important to identify some points for improvement in PAxSPL. We also could use the information gathered to improve the guidelines and give these information to be use as basis of comparison to future users.
