Techniques for validating requirements

The requirements should be documented, actionable, measurable, testable, traceable, related to identified business needs or opportunities, and defined to a level of detail sufficient for system design.Conceptually, requirements analysis includes four types of activity: Requirements analysis is a team effort that demands a combination of hardware, software and human factors engineering expertise as well as skills in dealing with people.Any changes in the requirements are also documented and go through a change control procedure and finalized on approval.A business plan or project requires a variety of requirements to help define goals and establish a scope for the work that will be undertaken.Here are the main activities involve in requirement analysis: Requirement analysis helps organizations to determine the actual needs of stakeholders.At the same time, it enables the development team to communicate with stakeholders in a language they understand (like charts, models, flow-charts,) instead of pages of text.Because a change to the requirements usually means the design and implementation must also be changed, and re-tested.During the requirements validation process, different types of checks should be carried out on the requirements.

A team of system customer; those who interact with the customer to gather requirements, and system developers start reading the requirements in the document, and investigate in a great detail to check for errors, inconsistency, conflicts, and any ambiguity.Ultimately, what we want to achieve is to develop quality software that meets customers' real needs on time and within budget.Perhaps the greatest challenge being faced by software developers is to share the vision of the final product with the customer.It’s difficult to show that a set of requirements does in fact meet a user’s need.Because users need to use the system in operation and imagine how that system would fit into their work.
