How Software Testing Works

Before the testing itself, we gather project information & define the best-fit approach. Our aim at this stage is to establish a sound testing process, bringing the most value with minimal efforts.
At this stage we:
  • Clarify and agree on goals, requirements & limitations
  • Define and document test approach, including KPIs & metrics
  • Present and discuss the approach with stakeholders
The testing activities start with validating the approach to ensure that the assumptions & decisions our quality assurance experts made are valid and fit the project goals & existing processes best.
At this stage we:
  • Integrate testing into development & delivery processes
  • Collect information according to the KPIs defined
  • Define improvement points & present results to stakeholders
Once the approach is refined & validated, we set up full-scale test support of the development process. In parallel, our experts continue improving the testing process to meet changing requirements.
At this stage we:
  • Regularly track and analyze KPIs and metrics
  • Provide ongoing updates on the project state for proper decision-making
  • Validate and implement changes to the process
