Software processes are the activities for designing, implementing, and testing a software system. The software development process is complicated and involves a lot more than technical knowledge.
That’s where software process models come in handy. A software process model is an abstract representation of the development process.
In this article, we will introduce you to the top seven software process models and discuss when to use them.
We will learn the following:

• 
  What is a software process model?
  
• 
  Factors in choosing a software process
  
• 
  Types of software process models
  
• 
  What to learn next

What is a software process model?
A software process model is an abstraction of the software development process. The models specify the stages and order of a process. So, think of this as a representation of the order of activities of the process and the sequence in which they are performed.
A model will define the following:

• 
  The tasks to be performed
  
• 
  The input and output of each task
  
• 
  The pre and post-conditions for each task
  
• 
  The flow and sequence of each task
  

The goal of a software process model is to provide guidance for controlling and coordinating the tasks to achieve the end product and objectives as effectively as possible.

There are many kinds of process models for meeting different requirements. We refer to these as SDLC models (Software Development Life Cycle models). The most popular and important SDLC models are as follows:

• 
  Waterfall model
  
• 
  V model
  
• 
  Incremental model
  
• 
  RAD model
  

• 
  Agile model
  
• 
  Iterative model
  
• 
  Prototype model
  
• 
  Spiral model
