Software prototypes, software engineering, advantages of software prototypes and use

In this tutorial, we try to answer the following questions;

  1. What are Software prototypes in software engineering?
  2. Advantages, disadvantages  of software prototypes
  3. When to use software prototypes

What are Software prototypes?

  • Software prototype is a dummy software. 
    • When a customer gives us the requirement, we designed the requirements and make a prototype for software.
  • Prototype gives us the feel of a maximum complete software. In some cases, it represents 100% complete software. But actually, it is not a complete software. It is just a dummy software to represent the software underdeveloped.

What are the advantages of software prototypes?

    • Customer and users are involved in all process.
    • If there is a problem in software, then customer tell us that we should change the design of the software. This leads to time-saving.
    • Reduced software development effort.
    • Helps in clearing the ambiguities in requirements.
    • Prototypes improve the;
      • Software Usability.
      • Software design quality.
      • Software maintainability. 
      • Reduced software development effort.

When to use Prototype model?

  • When we give a free end to a customer then he starts to change the software design again and again. Some psycho customers can take too much time to the software team.
  • When the software needs to have much interaction with the end users.
    • For example, following systems have a high amount of interaction with end users;
      • Web-based applications
      • Online systems
