Software Testing Services: Each Project Has Requirements

In the classic essay, one computer scientist has defined the critical role of requirements for software development as follows:

The strictest and only rule for building software systems is to decide exactly what you want to build. No other part of the conceptual work is as difficult as clarifying the details of technical requirements, including interaction with people, with mechanisms and with other software systems. No other part of the work spoils the result so badly if it is done poorly. Errors occurring at any other stage of the project are not so hard to correct. Providers of software testing services improve quality of developed IT products by examining them at each stage of their life cycle.

Each application or software system will serve its target audience that sees it as a tool to solve their problems namely expects it to improve quality of their lives. The total time spent finding out the needs of users is nothing else than a highly effective investment in the success of the project. If the developers do not record the requirements that the customers have already agreed upon, how can the requirements satisfy the needs of these customers? Even the requirements for software, not intended for commercial use, should be well understood. For example, this applies to software component libraries and tools created for internal use by the developers. User interface testing services are involved in inspecting the graphical user interface to ascertain that its meets its requirements specifications.

Often it is not possible to fully define the requirements before the preliminary design stage starts. In this case, you may act gradually in subsequent iterations: implement one portion of the requirements at a time. Be sure to wait for the customer’s response before moving on to the next cycle. You will have no excuse if you start writing code earlier than you review the requirements, before taking the next step. Iterative programming is much more expensive than iterative concept development.

People sometimes waste time allocated for writing requirements, but this is not the most difficult stage for the team. The most difficult thing is to elicit and collect these requirements. Initially, writing the requirements involves clarifying, developing and decrypting the data. A clear understanding of the requirements for the product gives you the confidence that your team is working on the problems you need and will come up with the best solution to fix them. Quality control companies check whether software products are developed in compliance with established norms and regulations.
