Innovative technical performance engineer solutions delivered by specialists


A major public sector department requested support from Expleo with testing of a critical mapping solution. The system is used extensively to facilitate annual grant applications. The application process is under EU regulation and delays in grant applications could result in considerable fines, meaning application performance is critical.

Expleo were engaged as Software Quality Assurance Partners to support the organisation on its digital transformation programme. Performance Engineering was provided to the client using our On-Demand specialist shared service.



  • Limited real world understanding of how the application was used by its end users
  • Mapping applications and associated customisations are technically challenging to test using typical performance testing techniques
  • Timescales for testing were limited and engagement was late in the software development lifecycle
  • Significant data and environment availability challenges
  • Regular code deployments throughout testing critically impacting performance testing assets

We are a dedicated team of specialist software professionals, with considerable experience of different clients, industries and technologies. The team provides bespoke, flexible and cost-effective services to enable clients to digitally transform at pace.
