Performance Feedback
Individuals working on 5 or more mystery shopping/observational research projects/ stages/ waves over a 12 month period must be given feedback on the quality of their work at least once per year, and a record of this must be kept. This feedback can be given on the telephone, in writing or face to face.(See section 4.20.4)
If problems or deficiencies are found on any work, appropriate feedback must be given before that individual's work is used, and the problems and action taken documented.(See section 4.20.4)
Validation
Every project must be validated, and this must be done in one of the following two ways:
- a computer search on 100% of data, or
- 100% sight edit logic checks
in each case looking for data appearing outside of the ranges deemed normal.
When work is conducted from a central telephone location, one of the following methods must also be used:
- a minimum of 5% of calls listened-in to (or taped if both sides of the conversation are recorded) and/or
- a minimum of 10% of calls being taped if only one side of the conversation is recorded.(See section 4.20.5)
