Need for modeling a process when a team writes down a description of its development process it forms a common understanding of the activities, resources and constraints involved in software development. Such models can be used to develop more precise and. In contrast to software life cycle models, software process models often represent a networked sequence of activities, objects, transformations, and events that embody strategies for accomplishing software evolution. For example, there are many specific software development processes that fit the spiral lifecycle model.
To overcome these drawbacks of waterfall model, in the mid1990s the agile software development model was proposed. Other examples are openup and agile unified process.

Each development organization has its own working process that it evolves for how it gets. The waterfall model emphasizes that a logical progression of steps be taken throughout the software development life cycle sdlc, much like the cascading steps down an incremental waterfall.
The waterfall model is believed to have been the first process model which was introduced and widely followed in software engineering. As the development process specifies the major development and quality assurances activities that need to be performed in the project, the development process really forms the core of the software process.
