What is Requirements Lifecycle Coverage?

The knowledge area of requirements life cycle management addresses the activities that a business analyst performs to manage and maintain requirements throughout the implementation process. The life cycle of requirements is a set of activities that organizations use to manage them. It involves monitoring, planning, analyzing, controlling, and communicating organizational criteria. As a result, effectively managing the life cycle of requirements may have a significant influence on the project’s success. Managing the requirement life cycle entails keeping track of them while also identifying relationships between designs, assessing modifications, and assisting in reaching an agreement on those modifications. Requirements life cycle management is the process of managing a project’s requirements throughout its life cycle. The goal of requirements life cycle management is to ensure that all of the analysis essential components – including the company, stakeholders, and requirements – are in sync with each other and that the solution correctly implements those demands and designs. Requirements management doesn’t finish when the solution is implemented; instead, it adds value as long as that solution is being used. The business analysts, in requirements life cycle management, utilize all six of BABOK’s main ideas (Change, Need, Solution, Stakeholder, Value, and Context). They are in charge of assessing modifications to requirements and designs and keeping stakeholders happy by maintaining requirements. The Business Analysts track the requirements of the solution components and ensure that the solution is in line with them. They work with interested stakeholders throughout the process of determining and approving needs. The objective is to keep requirements in a manner that will provide future value, which can be achieved only by comprehending the organization’s context in which these activities occur.
