What are Software Process Models?

The software model is the set of related activities that leads to the software products of the software product. These activities involve the software development process from scratch or modeling existing systems. Every software model provides the speedy development of any software product and supports every activity of software development from scratch to the end of development. Every software model is a simplified representation of the software process.

• Every software model represents the process from a different perspective.

• Every software development model must include the following activities.

Software specifications

This activity defines the product functionalities of the targeted system and the constraints involved in software development.

• Functionalities can be functional or non-functional in the targeted system.

• In Functional Requirement, we discuss the essential properties of the system. Without these properties system can't be functional

• In non-functional requirements, we discuss the properties of the system which can support the essential requirements of the system.

Software Design and implementation

This activity involves the implementation of the software product. This is the second step of software development.

• This step involves the implementation of the essential requirements of the system.

• This step involves the assurance of quality attributes.

Software Verification and Validation

This activity involves the verification of the customer's needs and expectations. This step consists of the validation and verification process of the first two-phase software specification and software design and implementation likewise, we check the system meets the customer requirement that we gather in the first phase of the requirement elicitation process.

Software Evolution

This activity involves modifying software to meet the customer and market new trends. Modification means improving the system to such standards that can support today's technologies and efficiently meet customer requirements.

Importance of Software Process Models

Software Process models have great importance in the development of software products. Every software model control, manage, guide, and monitor the software development process. Software process models give a clear way for the development process. We discuss some important reasons why software process models are important.

• Modern software products are faster and more efficient because they were built using certain engineered techniques these techniques are software process models.

• Modern software products are quality products because they were built using certain formal techniques during the development phase production house follows the software process models and test each step again and again to improve the quality of the product.

• Life Critical systems need more effective and efficient planning to complete the software product. In this situation, software process models give us the way of planning to complete such types of software systems.

• The modern software product is used to reduce the workload of a company and some origination needs software systems because they want the exact statistics of customers and if the software product failed to satisfy the needs of customers, then this type of software development is worse because this process had not used the software process models and leads to business failure.

• Software process models create the new logic for problem-solving based on open-ended programming environments for the high computer system.

• Guides the software development teams to make new methodology for the development and construction of software products.
  Software process models provide a flexible and supportive development environment.

• Using Software process models every organization can run more than one task at a time.
