ARCH.002 Create initial set of operational capabilities
Goal | Identify enough operational capabilities to provide a starting point for understanding the problem space |
---|---|
Requirements met by this process step | CSM-SMS guidance 1.1a) EN 50126-1 7.2.2 a) ISO 15288 6.4.1.3 b 2) |
Inputs | Business briefing material Knowledge of contributors |
Outputs | AMOD-021 Operational capabilities definition |
Methodology | Brainstorming using any practical method to identify candidates, then rationalise by agreeing a reasonable level and size of item. Model the capabilities in Capella. Multiple diagrams can be created to implement view AMOD-021, to keep diagram size acceptable. Diagrams could group capabilities on a similar theme. Capabilities may appear on multiple diagrams if they cross multiple themes. Note: it is not necessary to identify all dependencies/relationships between operational capabilities, nor to define very precise and synchronised start/end conditions at this stage. However, there should be some idea of these properties so that they can be used as a starting point for operational scenario analysis. They will be updated later in the process as more is learned about the capability set and the operational needs. |
Tools | Any practical brainstorming tools + appropriate environment Team for Capella |
Cardinality | One-off at the beginning of the project. Revisions allowed to the whole set based on what is learned during analysis of the individual capabilities. |
Completion criteria | The participants in brainstorming agree that a reasonable level of coverage has been achieved; The output model views comply with their model specification and modelling rules; The accountable role judges that a reasonable level of coverage has been achieved. |
