What is Requirements Analysis

One traditional way of documenting requirements has been contract style requirement lists. In a complex system such requirements lists can run to hundreds of pages long. Those organizations who integrate horizontally with the organization for whom the analyst is designing the system. Organizations responsible for systems which interface with the system under design. Documenting dependencies and interrelationships among requirements, as well as any assumptions and congregations.

Review (Revision)

Unlike the traditional requirement capturing, user story focuses on what the user need instead of what the system should deliver. User stories are well compatible with the other agile software development techniques and methods, such as scrum and extreme programming. A UML use case diagram is the primary form of system/software requirements for a new software program under developed.

As a Business Analyst, requirement analysis is the most important part of your Job.

The discovery of user needs and requirements benefit from techniques like the data flow diagram. As mentioned, they can be created early and give a high-level view of the data flow within a particular process. Use cases and user stories are also great tools for soliciting software requirements from a user perspective, as they maintain focus on what the user needs, not what the product does to meet those needs and wants. Requirements analysis is a critical part of the requirements definition and management process in software development. The purpose of requirements analysis is to be sure all product requirements accurately represent stakeholder needs and requirements. When executed correctly, requirements analysis results in a set of product requirements that, when met, will result in a deliverable that matches stakeholder expectations.

These are usually the stakeholders most impacted by the project, and requirement phase their needs combine to define the ideal project outcome. Requirements analysis in software engineering empowers project managers and leaders to maintain clear direction, keep users’ needs front-and-center, and develop comprehensive documentation of the development process. Requirements analysis in software engineering is usually an iterative, continuous process throughout a project’s duration, not a one-and-done task.
