Requirement analysis is the process of determining user expectations for a new or modified product and is vital for effective software testing as it lays down the basic foundation for various stages of the SDLC. Without a thorough need analysis and a clear road-map, even the most efficient system architecture, well-written code, or comprehensive testing will prove futile.
Hence, the first step to kick-off any project is “Requirement Analysis”. And to be useful, requirements should be scripted, actionable, quantifiable, traceable and directly linked to the business needs or opportunities.
Requirement Analysis Process
A typical Requirement Analysis process should identify testable requirements through frequent interactions with various stakeholders (Client, Business Analyst and Technical Leads etc.). The intent is to brainstorm and clarify any ambiguous requirements before getting to the next phase and to precisely define the Automation needs for the project.
For this, QA should be involved early on in the project ensuring that issues are identified before they become defects, even prior to the completion of the technical design. This, in turn, saves considerable time and money.
Any lacunae in requirement analysis will have a huge bearing on project timelines, quality, and costs, and may become the sole reason for the project failure because the further you go into the STLC, lesser are the chances of the bug getting detected and fixed.
However, with the influx of new and disruptive technologies, analyzing and validating the testing requirements is not an easy task. Besides, there are few typical challenges that further complicates the requirement analysis process.
Common Challenges in Requirement Analysis
Normally, in the early stages, the project scope is not well-defined and there is a lack of clarity in the processes. Additionally, involving all the stakeholders, understanding their viewpoints, and precisely defining the requirements is not a straightforward task.
If the business needs are not clearly specified or there are conflicts around an ambiguous term, or there is a constant inflow of frequent new requirements, the task gets even more complicated.
Here, including QA team in the process can assist in better understanding the requirements to deliver a quality product as QA tends to be detail-oriented and looks for quantifiable metrics.
Role of QA
Quality Analysts play a vital role in requirement analysis by ensuring each requirement is analyzed from the specification document, and then lists down high-level scenarios. The early involvement enables testers to plan their testing from the live understanding of the requirement definitions.
Any ambiguity is clarified and functionalities are defined by asking relevant questions and seeking explanations.The project risks are identified and defect tracking methodology is established. And finally, a Requirement Traceability Matrix is prepared that maps and trace user requirements with test cases. It ensures all the test cases are covered and no functionality is missed.
Now, with everything in place, the tester is ready to sign-off from the Requirement Analysis Phase after ensuring a sound foundation has been laid.
At Astegic, we have developed a comprehensive Testing Requirement Analysis Framework (TRAF) to cater specifically to the requirement analysis needs of the businesses. TRAF assists in rapid QA/Testing project set-ups and ensures prevention of early defects encompassing the three most critical aspects of the testing requirement process- Scope, Coherence, and Consistency.
Equipped with experienced and skilled resources with access to the latest tools and technologies, we enable businesses to speed up their testing requirement analysis time and achieve superior quality in a cost-efficient manner.
