The project at a glance

Cerqual is aiming to play a leading role in the digital transition in the housing sector. In 2015, certification body Qualitel began digitizing key housing quality assessment processes, which had previously relied on hard-copy documents and Excel spreadsheets. For phase one of the process, it asked Hardis Group to develop a single, standardized, more efficient system for housing acoustic assessments.

Project objectives

  • Digitize and standardize the acoustic assessment process
  • Create a practical, user-friendly system fully aligned with user needs
  • Support major shifts in business practices
  • Trial agile methods to streamline development and increase uptake

Work performed

  • Test sprint to persuade Cerqual to commission Hardis Group to perform the work
  • Agile development of a business application: 550 person-days (450 for Hardis Group, 100 for Cerqual)
  • Application testing and acceptance testing


  • User-friendly system fully aligned with user needs (involvement of an acoustics experts on a part-time basis, plus consultation of three super-users at all times throughout the project)
