The employees of software testing company should not only have profound knowledge of various testing techniques and principles, use different checking tools during automated testing[1] but also be aware of main software development models.

Software development and testing fields are interconnected. It will be easier to conduct performance testing or load testing[2] for a tester who knows the peculiarities of development models. The Waterfall model[3] is one such development techniques.

This model was described by W. Royce in 1970. It is considered to be a classic example of the philosophy ‘plan the work and work the plan’. It is a rather popular version of the software development life cycle model. The Waterfall Model [4]consists of several typical phases.

What Are Waterfall Phases?

• Analyzing and defining system requirements.
• Analyzing and categorizing software requirements.
• Detecting of program design (architecture, interface, etc. that define the system).
• Implementation of the design with the help of code. This is the actual phase of programming.
• Testing procedure. The requirements should be understood in a proper way, and at the same time, the system design should meet all required specifications.
• Putting the system into production.

The Waterfall model has a strict order, and every step can be easily controlled. The main disadvantage of this model is the absence of the possibility to somehow modify the development order.
