Abstract
This panel looks at
product derivation approaches and their differences, strengths and weaknesses
in different PLE situations. Each panelist will examine a common problem (the
Interactive Television Applications)
and provide an overview of their product derivation approach and how it was
used to solve the problem.
Overview
At some point, no
matter how wonderful your product line process is, you have to ship the
products. The panelists will each present a different approach to PLE,
concentrating on how actual products are derived from specifications. The
approaches presented include feature modeling, architecture description
languages, UML and domain-specific modeling languages.
A common product specification and derivation task will be given to all panelists, and they will show how their approach works on it. The audience can - and is warmly encouraged to - participate, ask additional questions, heckle, and hopefully laugh. A major goal is to identify the classes of PLE situations that best suit each approach.
Following are some of the questions and issues to be addressed by the panel.
- How large a portion of a product is automatically derived? Please answer in terms of some reasonably precise measure, such as percent of modules, classes, or KNCSL, or coverage in a feature model.
- How are new features and functionality developed? Give an example, if possible.
- What is the cost and time to create a new feature or change the application platform, e.g., in hours of effort as a fraction of effort needed to create the application engineering environment? Alternatively, how would you estimate the cost and time?
