How to gather performance requirementsĪlthough gathering requirements is an essential part of the software development process, it can be a daunting challenge. Design and test software with dependencies in mind. For example, a bottleneck accessing SQL will adversely impact the software's response time returning the data. A software project that relies on OS services or access to an enterprise database must contend with the performance limitations in these separate components. When you establish performance requirements, consider the influence of dependencies. In another example, the expected battery life on a hardware device can impact the strength of the lighting on a visual display, potentially degrading usability. But higher throughput can degrade response time, which is how quickly the software delivers what the user requested. One example is among different types of performance requirements: High-throughput performance is the ability to process a large volume of transitions within a timeframe. Some quality attributes can conflict with one another and require the business to make tradeoffs. What are software quality requirements?Ī development team should consider performance requirements along with other types of quality attributes: reliability, robustness, security and usability as well as availability, interoperability, safety, efficiency and flexibility. Like most quality attributes, performance requirements are key elements in the design and testing of a software product. The service levels comprising performance requirements are often based on supporting end-user tasks. Examples include the software's speed of response, throughput, execution time and storage capacity. Performance requirements define how well the software system accomplishes certain functions under specific conditions. ![]() Consider performance requirements as a type of quality attribute, a category of nonfunctional requirements. There are two types of requirements in software requirements specifications: functional and nonfunctional.
