3 Domain Analysis for Product-Line Architectures

Sunday, 26 October – 8:30-12:00 Morning

Neil Harrison, Avaya Labs Research, nbharrison@avaya.com
Frank Buschmann, Siemens AG, Corporate Technology, Frank.Buschmann@siemens.com

Product-line architectures promise better productivity and less maintenance costs for families of related software systems. A strong product-line architecture is one of the keys to a successful deployment of both product lines and any system destined to go through multiple releases. However, specifying high-quality product-line architectures is a surprisingly difficult task.

Commonality and variability analysis is a powerful domain analysis tool for the specification of product lines. It can help designers produce systems that are robust in the face of change, and that can be easily customized. Additionally, it feeds naturally into OO design. This combination provides a proactive, systematic approach to accomodating changes in software.

This tutorial introduces commonality and variability analysis in a real-world setting. Topics include: underlying principles, methodology, and synthesis with OO design. By the end of the tutorial, you will understand how to use commonality and variability analysis in your OO projects to specify a stable, yet flexible, software architecture.

Attendee background

This tutorial is aimed at architects and designers of systems that have many variations, such as product families and systems with multiple releases.

Prerequisites: Attendees should have solid background in OO principles, and some OO design experience. Experience in specification or analysis is helpful but not required.
