Staged Configuration
• A Feature Model describes the configuration space of a system family.
• The process of specifying a family member may be performed in stages.
• In each stage, some configuration choices are done. Resulting in a subset of the initial Feature Model
• This Process is called Staged Configuration.
Configuration vs. Specialization
• Configuration
– consists of the features that were selected according to the variability constraints defined by the feature diagram.
– The relationship between a feature diagram and a configuration is comparable to the one between a class and its instance in object-oriented programming.
• Specialization
– is a process to transform a feature diagram and yields another feature diagram, such that this last diagram denotes a set of configurations that is a subset of the first one.
– A fully specialized feature model denotes only one configuration.

Staged Configuration
• The need for staged configuration arises in at least three contexts:
– Software Supply Chains;
– Optimization;
– Policy Standards

Optimization
• Staged configuration offers an opportunity to perform optimizations based on partial evaluation.
• When certain configuration information becomes available at some stage and it remains unchanged thereafter, the software can be optimized.
• For example, configuration information available at compile-time can be used to eliminated unused code.
• Optimizations are especially interesting for embedded software and software that need to be distributed through a network connection.

Proposal
• Use a Multi-Agents approach to help the stakeholders to configure the feature model.
• Study techniques to resolve conflicts where there is some dependencies between features.
• Extend the work from static configuration to dynamic reconfiguration.
