Explain the popular Software development life cycle models.
This is the oldest model. It represents sequence of stages; output of one stage
becomes input of others.
This is improved version of waterfall model. Here we have scope to reiterate
and go back to the earlier stages number of times as project progresses.
Build and fix model
This is a risky and most unorganized model. In this, developers keep writing
code until the customer is happy.
Rapid Prototype Model
In this model, we develop prototype which acts like a final product. Once
prototype is approved, then the actual development starts.
In this model, the product is divided into sections and each section of the
product are created and tested separately.

Explain project life cycle.
Waterfall Model: The waterfall model is a software development
process which follows a sequential approach. This approach steadily flows
downwards like a waterfall which includes the phases of conception, initiation,
analysis, design, construction, testing and maintenance.
Spiral Model: The spiral model is one of the software
development processes which combines the design and prototyping-in-stages
together to gain the advantage of top-down and bottom-up approaches.
Build and Fix model: This model is one of the worst model for
project development. The project is built without specifications and lacks
design steps. Essentially, the project is developed, tested, modified as many
times as possible. This process continues until the client’s satisfaction is
attained. The cost is greater compared to other models. The software engineers
are discouraged to use this model.
Rapid prototyping Model: To determine and identify the design
flaws and obtaining feedback during design process is done by using rapid
prototyping model. Product designers and engineers are allowed to view their
designs look and function in real world situations by using Rapid Prototyping
Incremental Model: The evolution of waterfall model is
incremental model. The integration testing, product design and development is
done as a series of incremental builds. A popular software evolution model used
by many software companies. Incremental model is suitable and applicable where
software requirements are well defined, but their implementation may be
delayed; and the basic software functionality are required early.

Answer - At this level, there is no proven processes and
has no stable environment in the organization. This type of organization......
