Product line is a common enough term from any manufacturing processes, but what are software product lines?

Behind the link you will find a paper about frameworks for software product lines. The beginning (around pages 5-10, and introduction) the nature of software product lines is discussed. Read those parts and answer following questions:

• What is the role and aim of software product lines/the idea behind them?

• Why is the role and support of management even more important when using software product lines than in "traditional" software development?

• What kind of benefits software product lines may yield?
