Evolutionary product line requirements engineering

Product Line Engineering has a widespread use in industry now. Therefore there is a high need for customizable, adaptable, and also for mature methods. Scoping and product line analysis are a unique and integral part of Product Line Engineering. In these phases we determine where to reuse and what to reuse, establishing the basis for all technical, managerial, and investment decisions in the product line to come. Furthermore, these early phases are highly context dependant. In this tutorial we will give an introduction on how to analyze an environment with the purpose of planning a product line and its future evolution. We focus on product line requirements engineering methods, comprising product line scoping, analysis, and planning for evolution.
