The earliest stage in the application's SDLC at which performance efficiency testing can be performed is during requirements analysis. At this stage, performance requirements and goals are established, providing a baseline for what needs to be tested and verified throughout the later stages of development​​.

A service virtualization tool is used to simulate the behavior of specific components in heterogeneous component-based applications such as APIs, services, and third-party apps that are not readily accessible during development and testing stages. These tools help create stable, controllable, and predictable testing environments by mimicking the interactions with the missing components. This is particularly useful when dealing with server or network traffic log data to develop a shareable testing service that replicates the real systems' behavior without their actual implementations.

Static analysis is used on an Agile project to identify the causes of technical debt through the use of tools. This approach allows teams to detect potential issues in code that could lead to technical debt if not addressed promptly, thus maintaining the health of the codebase as it evolves rapidly in Agile environments .
