Question

which model is used when customer define set of general objective for software but does not identify detail input processing or output requirements?​

Answer 1

Answer:

Software specification (or requirements engineering): Define the main functionalities of the software and the constrains around them.

Software design and implementation: The software is to be designed and programmed.

Software verification and validation: The software must conforms to it’s specification and meets the customer needs.

Software evolution (software maintenance): The software is being modified to meet customer and market requirements changes.

In practice, they include sub-activities such as requirements validation, architectural design, unit testing, …etc.

There are also supporting activities such as configuration and change management, quality assurance, project management, user experience.

Answer 2

Answer: Prototyping Model

Explanation

The prototyping model is frequently employed when a customer specifies a list of broad software objectives but does not specify specific input processing or output criteria.

An early, or "prototype," version of the software is created using the iterative prototyping process for software development. Together, the customer and development team determine the broad goals for the software, after which the latter produces a functional prototype for gathering input and fine-tuning the specifications. The consumer isn't completely happy with the finished product until this process is repeated multiple times.

The prototype model's benefit is that it enables a more adaptable and iterative method of software development. The customer can view and interact with a functioning version of the programme, which aids in honing the specifications and making sure the finished product satisfies their demands. As the development process moves forward, the criteria are continuously improved and tested, which reduces the risk of developing a product that does not satisfy the customer's requirements.
