  abstract = {Agile methods and product line engineering (PLE) have both proven
	successful in increasing customer satisfaction and decreasing time
	to market under certain conditions. Key characteristics of agile
	methods are lean and highly iterative development with a strong emphasis
	on stakeholder involvement. PLE leverages reuse through systematic
	approaches such as variability modeling or product derivation. Integrating
	agile approaches with product line engineering is an interesting
	proposition which - not surprisingly - entails several challenges:
	Product lines (PL) rely on complex plans and models to ensure their
	long-term evolution while agile methods emphasize simplicity and
	short-term value-creation for customers. When incorporating agility
	in product line engineering, it is thus essential to define carefully
	how agile principles can support particular PLE processes. For instance,
	the processes of defining and setting up a product line (domain engineering)
	and deriving products (application engineering) differ significantly
	in practices and focus with implications on the suitability of agile
	principles. This paper presents practical experiences of adopting
	agile principles in product line planning (a domain engineering activity).
	ThinkLets, i.e., collaborative practices from the area of collaboration
	engineering, are the building blocks of the presented approach as
	they codify agile principles such as stakeholder involvement, rapid
	feedback, or value-based prioritization. We discuss how our approach
	balances agility and the intrinsic needs of product line planning.
	A case study carried out with an industrial partner indicates that
	the approach is practicable, usable, and useful.},
