System Requirements & Functions

Systems are described at the top level by System Requirements and Functions (features). Requirements only describe abilities or properties in the “problem area”, so they are still independent of concrete system solutions. The solution space is already limited by the Quality Attributes & Constraints . Interfaces to neighboring systems in the environment and their properties…

System increments are mostly created by the Application teams of the Cluster i.e. by integrating partial results of the different teams of a cluster (module and platform…

System Concepts & Capabilities, Solution Options

System concepts describe possible solutions for system and product variants (applications = feature sets) and their requirements . System concepts implement the System Requirements within the restrictions (contraints) and balance the quality requirements (Quality Attributes)out. The P4 framework explicitly provides several System Concepts as solution options for the implementation of System Requirements in the system…
