In the first part of this research, academics and industry experts were asked to nominate the names of retail organisations they believed delivered consistently low shrinkage results.
From this, a list of five retailers, all based in USA, were identified and in the second part of the research, they were all contacted and a request for an interview and site visits was agreed with each of them.
From the interviews and the observations, the researcher (Professor Adrian Beck) was able to identify ten 'habits' that explained the approaches they were taking to keep their losses low. This was published in the form of a report, and then an article in the Harvard Business Review.
