In previous work, we have shown a model-driven approach (called EvoPL [21]) for planning and managing long-term evolution of product lines. It allows specifying historic and planned future evolution in terms of changes on feature model level. It provides benefits like abstraction, efficiency through automation, and the capability to perform analysis based on models. In this paper, we argue that specifying changes alone is beneficial but not sufficient. This is because for strategic evolution planning "decision drivers" like goals, requirements, and rationale are essential information as well. Hence, we propose a modeling approach that represents such decision drivers and their interrelationships. The approach is based on concepts from literature (e.g., QOC and goal-oriented requirements engineering) and combines and extends them to address the specific needs of model-driven long-term evolution management. Beyond the basic usage for documentation, the suggested models can be used for systematic future planning and tool-supported analysis, e.g., to evaluate the consistency of planned evolutionary changes.
