design
subject			fact

design	has definition The problem-solving process whose objective is to find and describe a way to implement the system's functional requirements, while respecting the constraints imposed by the non-functional requirements, and while adhering to general principles of good quality
	determines how components will be implemented in a system
	has goals Increasing profit by reducing cost and increasing revenue Ensuring that we actually conform with the requirements, thus solving the customers' problems Accelerating development, which helps reduce short-term costs, and may also ensure the software reaches the market soon enough to effectively compete Increasing qualities such as usability, efficiency, reliability, maintainability, and reusability which can help reduce costs and also increase revenues
	has part detailed design
	has part modelling
	has part programming
	has part software architecture^2
	has part systems engineering
	has part user interface design
	is a subtopic of 9.1 - The Process of Design
	is a kind of process
	requires considerable experience
	see also design^2

Kinds of design :

• algorithm design (3 facts) - The design of computational mechanisms
• architecture design (4 facts) (software architecture^2)
• bottom-up design (1 kind, 4 facts) - An approach to design in which you start by designing the low-level details such as the utilities, and then decide how these will be put together to create successively higher-level components, and ultimately the entire system
• class design (3 facts) - The design of the various features of classes such as associations, attributes, interactions and states
• database design (3 facts) - The design of how data is persistently stored so that it may be accessed by many programs and users, over an indefinite period of time
• defensive design (3 facts) - Design with awareness that other components cannot be trusted
• design by contract (3 facts) - An approach to design in which each method has a contract with its callers regarding preconditions, postconditions and invariants
• detailed design (5 facts) - The design of the internals of individual subsystems
• object oriented design (7 facts) (OOD)
• protocol design (3 facts) - The design of communications protocols
• software architecture^2 (9 facts) (architecture design) - The process of designing the global organization of a software system, including dividing software into subsystems, deciding how these will interact, and determining their interfaces
• top-down design (1 kind, 4 facts) - An approach to design in which one starts with the high-level architecture of the system, then elaborates the design of subsystems until finally designing the low-level details such as the structure of individual classes
• user centred design (16 facts) (UCD) - An approach to software engineering using techniques that focus on users and their needs
• user interface design (9 facts) - The design of the user interface of a software system
