Requirement Gathering
It is a first of any software product.
It start when you thinking about developing S/W.
In this phase, you meet customers, analyzing market requirement and feature that are in demand.
Spend some time in research and analysis.
Requirement analysis
It is the process of determining user demand for new or modified product.
The requirement must be quantifiable, relevant and detailed are called functional specification.
Requirement analysis involves following activities
Requirement must be actionable, measurable, testable, related to identified business needs.
Requirement can be functional and non-functional
Steps in requirement analysis process are given below….
Software requirement specification
Detailed description of the software that is developed for the software.
SRS is fully describe what the software will do.
How it will expected to perform.
The SRS minimize the time and effort and development cost.
Functional requirement
It describe each of the function that the system needs to perform along with corresponding input and output data set.
The constraint on the function of a system may describe certain things that the system should or should not do.
For example a constraint on a function can describe how fast it can produce result.
Traceability:
It is an important concept and frequently used during software development.
Used to study the impact of a bug on various requirement.
Which part of the design and code would be effected.
