Quality and Usability

Usability Workbench for Rapid Product Development (MeMo)

MeMo predicts future usability with minimal human involvementMotivation & Project Description

  • Today: One-shot usability testing with users or own employees for a few selected products
  • With MeMo: Automatic testing in the workbench; final user testing with already optimized system. -> Significant reduction of test cycle duration and of time-to-market
  • Without MeMo: Decrease of DTAG’s service acceptance by end users -> increased support cost and churn rate
  • MeMo will enable usability testing of products as well as testing of ideas and concepts; MeMo workbench can help to decide on market launch of a product now or to iterate development.


  • Workbench for accelerating usability evaluation cycle, including a database of models for different user groups
  • Algorithm for predicting usability on the basis of (semi-) automatic model annotations
  • Decision support for market launch and system optimization
  • Reduction of time to market in e-Business from 9 to 6 month.
