Software Processes
A software process is the set of activities and associated outcome that produce a software product.
Software engineers mostly carry out these activities. These are four key process activities, which
are common to all software processes. These activities are:
Software specifications:
The functionality of the software and constraints on its operation must be
defined.
Software development:
The software to meet the requirement must be produced.
Software validation: The software must be validated to ensure that it does what the customer
wants.
Software evolution: The software must evolve to meet changing client needs.
Software Development Life Cycle (SDLC)
A software life cycle model (also termed process model) is a pictorial and diagrammatic
representation of the software life cycle. A life cycle model represents all the methods required to
make a software product transit through its life cycle stages. It also captures the structure in
which these methods are to be undertaken.
Different life cycle models may plan the necessary development activities to phases in different
ways. Thus, no element which life cycle model is followed, the essential activities are contained in
all life cycle models though the action may be carried out in distinct orders in different life
cycle models. During any life cycle stage, more than one activity may also be carried out.
