1. Jacobson et al. define variation point as "one or more locations at which the variation will occur" [Jacobson et al. 1997]. This definition is similar to the definition presented in this book, but Jacobson et al. focus on UML models, whereas this chapter takes a more general view on variability by linking variability in the real world and variability in software product lines. Furthermore, our definition emphasises that a variation point exists in a certain context.
2. We use single quotes when we refer to the elements of a figure, such as 'colour' in Fig. 4-2.
3. Svahnberg et al. deal with resolving variability at different stages of software product line engineering in [Svahnberg et al. 2001].
4. The amount of variability is introduced as an abstract entity here. The reader can think of the amount of variability as a measure based on the number of variation points, variants and variable artefacts.
