Test procedures for compliance testing with Usability Standards - why?


Cologne, 13 January 2005



Usability standards can only be applied when the context of use is well-known, i.e. the implied requirements in a product's context of use. Standardized test procedures help ensure that test results are based on validated usability requirements and are thus reproducible within a specified context.

Usability standards differ from technical standards, which specify technical product features to be followed regardless of the individual context (e.g. the height of a dish washer).

Two standard test procedures have been developed by the German body for accrediting test laboratories (DATech), with one of the test procedures being devoted to the test of products and another one to the assessment of processes.

  • The DATech test handbook for compliance testing of products with ISO 9241 parts 11 and 110 is internationally the first standard usability test for conformity with ISO 9241 part 10 and 11.
  • The DATech test handbook for compliance testing of usability-engineering processes with ISO 13407 is intended for assessing user-centred design processes for conformity with ISO 13407.
The two DATech test procedures are the mandatory test procedure within DATech accredited usability laboratories. DATech does not claim to have created the one best way of testing products or processes, but offers a consensus about usability testing that has been achieved among interested partners in the German software industry, professionals in German laboratories, and German research institutes.

DATech test procedures for testing and evaluating the usability of interactive products based on ISO 9241, part 10 and 11. The German title is "DATech Prüfhandbuch Gebrauchstauglichkeit". The test procedures are periodically updated by members of a standing committee of DATech. The latest version can be downloaded. Note: This document exists in German only.
