The document discusses various design principles and processes, focusing on both descriptive and prescriptive models of design. It outlines several strategies for software design, including the V model and spiral model, while emphasizing key principles such as modularity, separation of concerns, and conceptual integrity. Additionally, it addresses challenges in design and suggests heuristics to improve the design process.

- 1. DESIGN PRINCIPLES By: Roberto Merino A. DESIGN PROCESSES The Context of Design Generic: Descriptive Models Strategies: Prescriptive Models Decompositional methods Compositional methods Design template and design reuse Incremental and evolutionary design strategies V Model Postulating a number of solutions Building a model of each solution Evaluating the models against the original requirements Comparing the validated solutions and select one for further development Elaborating the model to produce a detailed specification of the solution in the form of ‘blueprint’. Spiral Model STRUCTURE OF SOFTWARE DESIGN METHODS Heuristics Process Representation DESIGN PRINCIPLES BASIC RULES OF SOFTWARE DESIGN Basic rules of software design Vehicles to overcome difficulties Causes of difficulties Complexity Conformity Changeability Invisibility The principle of modular designs The Axiom of Separation of Concerns The Axiom of Comprehension The Axiom of Translation The Axiom of Transformation The principle of portable designs The principle of malleable designs The principle of conceptual integrity The principle of intellectual control The Principle of visualisation
