What are the characteristics of the good software design & improve understandability?

Six of the most important quality characteristics are maintainability, correctness, reusability, reliability, portability, and efficiency. Maintainability is “the ease with which changes can be made to satisfy new requirements or to correct deficiencies” [Balci 1997].

What are the characteristics of the software?

These components are described below:Functionality: It refers to the degree of performance of the software against its intended purpose. … Reliability: … Efficiency: … Usability: … Maintainability: … Portability:

What are the design principles of software?

Software design principles are concerned with providing means to handle the complexity of the design process effectively. Effectively managing the complexity will not only reduce the effort needed for design but can also reduce the scope of introducing errors during design.

What is software design basics?

Software design is a process to transform user requirements into some suitable form, which helps the programmer in software coding and implementation. … Software design is the first step in SDLC (Software Design Life Cycle), which moves the concentration from problem domain to solution domain.

What are non functional requirements of a system?

Nonfunctional Requirements (NFRs) define system attributes such as security, reliability, performance, maintainability, scalability, and usability. They serve as constraints or restrictions on the design of the system across the different backlogs.

How can we characterize a good software design?

Now, let us define each of them in detail,1) Correctness. First of all, the design of any software is evaluated for its correctness. … 2) Understandability. The software design should be understandable so that the developers do not find any difficulty to understand it. … 3) Efficiency. … 4) Maintainability.

Which is the most important feature of spiral model?

The most important feature of the spiral model is handling these unknown risks after the project has started. Such risk resolutions are easier done by developing a prototype. The spiral model supports coping up with risks by providing the scope to build a prototype at every phase of the software development.
