For the success of a project, it is utmost important to analyze project requirements when they are gathered as well as throughout the lifecycle of the project. Requirements analysis helps to keep the requirements in line with the need of the business. A good requirements analysis process will render a software application that caters to the objectives of the business set forth.
Requirements Analysis is the process of defining the expectations of the users for an application that is to be built or modified. Requirements analysis involves all the tasks that are conducted to identify the needs of different stakeholders. Therefore requirements analysis means to analyze, document, validate and manage software or system requirements. High-quality requirements are documented, actionable, measurable, testable, traceable, helps to identify business opportunities, and are defined to a facilitate system design.
The process of gathering requirements by communicating with the customers is known as eliciting requirements.
This step helps to determine the quality of the requirements. It involves identifying whether the requirements are unclear, incomplete, ambiguous, and contradictory. These issues resolved before moving to the next step.
In Requirements modeling, the requirements are usually documented in different formats such as use cases, user stories, natural-language documents, or process specifications.
This step is conducted to reflect on the previous iterations of requirements gathering in a bid to make improvements in the process going forward.
There are different techniques used for Requirements Analysis. Below is a list of different Requirements Analysis Techniques:
· Business process modeling notation (BPMN)
· UML (Unified Modeling Language)
· Flowchart technique
· Data flow diagram
· Role Activity Diagrams (RAD)
· Gantt Charts
· IDEF (Integrated Definition for Function Modeling)
· Gap Analysis
