Improving the Effectiveness of Visual Inspection


Upcoming Courses


Human visual inspection is the most common method to confirm the quality of work, whether in manufacturing or service industries. Yet it is very common to assume not much can be done about the generally low reliability of visual inspection – to err is human!

For people interested in improving visual inspection practice, few resources have been available – until now. The course “Improving the Effectiveness of Visual Inspection” provides you with the information needed to understand the factors of influence on the human task of visual inspection, permitting true quality engineering of this critical operation. The course is based on Ted Schorn’s 2018 book of the same name (provided with the course) that summarizes the research into visual inspection through hands-on learning and interaction with the author.
