Sources of cognitive bias and their impact on software testing

This presentation considers in easy terms the principal way in which people think and take decisions. It is critical to understand this when evaluating ROI, conducting estimations and setting up appropriate test strategies.

The main sources of cognitive bias are considered with regard to their impact on software testing issues, such as:

  • Creating risk-based test strategies
  • Evaluating the return on investment from testing
  • Estimating testing effort

 Graham Bath can look back on more than 20 years of professional experience in testing.For him, the main attraction of the work of a tester is  that it combines so many different technologies and colleagues.

 He works today as Principal Consultant at T-Systems, Test Factory.Graham Bath’s activities reflect at the International Software Testing  Qualifications Board (ISTQB®) as member of the Advanced Level and Expert Level working groups. At national level, he is leader of the  Advanced Level and Expert Level working groups for the GTB, who are responsible for the creation of the syllabi in German.
