Software Engineering:

During the architectural design step we specify the internal details of each component. A good architectural style supports all quality features. Activity diagrams can represent any process and are useful throughout software design. Regarding activity diagrams, an activity is an atomic task or procedure that cannot be broken into parts. Regarding activity diagrams, an initial node produces a token on each outgoing edge when an activity begins. Architectural design is high-level software engineering design analysis. Software requirements specification (SRS) is the main input for the product design process. Project Mission Statement Template includes "Business Requirements." With respect to product design principles, simplicity means: A design is acceptable only if it is simple and easy to understand. A set of requirements is consistent if it includes every relevant requirement. Every use case diagram must have at least one actor associated with each use case. UML use case diagrams are dynamic models of all the use cases in a product. Postconditions must be true when the use case ends whether it is successful or not. Use case models provide atomized requirements statements. Product Design Principles include feasibility, usability, economy and changeability
