Aggregation Levels in Composable Architectures

abstract The creation of a Product Family is an alternation of decomposition and synthesis steps. Composable architectures emphasize the composition of products, decreasing the importance of a priori decomposition. The products and intermediate compositions can be viewed as recursive aggregation levels. Careful trade-offs are required between the size of an aggregation level and the way it will be deployed. Flexibility and (configuration) manageability amongst others are balanced.

This article shows multiple viewpoints with respect to aggregation levels, the concerns per viewpoint and the relevant entities per viewpoint. For every viewpoint heuristics are given for the level of granularity.

This article is to be used in the "Family Engineering Handbook", a collective effort of Philips Research employees to consolidate family engineering based experiences.
