Each software project emerges out of a business issue. The requirements analysis process attempts to find the business issue to be understood and probable characteristic a software product needs as an answer for the business issue. Requirements analysis is the establishment on which software is built.

Managing and gathering requirement analysis document is one of the greatest difficulties faced in a project, and a powerful requirements management process is one of the stepping-stones to a successful project.

From the viewpoint of a tester, the requirements analysis process is utilized to decide if the system displays proper behavior for each test case. Thus, the quality of a requirement gathering and analysis greatly affects the quality of the completed software.

Due to this, a requirement analysis phase should be finished, consistent, right, and unambiguous. Otherwise, defects may stay undetected, resulting in the conveyance of a flawed software product to the clients.

Requirements Analysis Process is the initial phase of STLC and it begins when the SRD/SRS is imparted to the testing team.

Let’s consider the accompanying points to understand the Requirement Analysis in STLC:

• The entry criteria of this stage are the arrangement of software requirement specification. It is additionally prescribed that application architecture is convenient.
• In this stage, the QA team analyzes at a high level of what to test and how to test.
• The QA team catches up with different partners like Business Analyst, System Architecture, Client, and Test Manager/Lead if any inquiry or clarification is required to understand the project requirement analysis.
• Requirements may be non-functional and functional like usability, security, performance and so on.
• The exit criteria of this stage are to complete the automation feasibility report, RTM document, and a rundown of inquiries if applicable to be more specific on the requirements engineering.

Requirement Analysis Steps:

The Requirements Analysis Methods include the accompanying steps:

Eliciting Requirements:

The way toward requirements gathering by speaking with the clients is known as eliciting requirements.

Analyzing Requirements:

This progression decides the quality of requirements. It includes recognizing whether the requirements are hazy, inadequate, equivocal, and opposing. These issues settled before moving to the next step.

Requirements modeling:

In Requirements modeling, the requirements are generally recorded in various formats like user stories, use cases, process specification, or natural-language documents.

Review and retrospective:

This step is led to ponder the past iterations of requirements gathering in an offer to make upgrades in the process going ahead.

Need of Requirements Analysis Process

As per statistics major reason for the failure of software is that it doesn’t meet with the requirements of the client. It is possible that over years the requests of the customer increase and there can come a requirement of updating the product.

Requirement analysis includes the tasks that decide the requirements of the product, which for the most part incorporates complaints and needs of different customers/partners. It is a noteworthy key in the life-cycle of software testing and is the beginning step of the project.

For the accomplishment of a project, it is most extreme critical to analyze project requirements when they are accumulated just as all through the lifecycle of the task. Requirements analysis keeps the requirements in accordance with the need of the business. A good requirements analysis process will render a product application that obliges the targets of the business put forward.
