The answer to this is rather simple to describe, but more complex to implement, particularly the collection of the data. A simple approach is to identify the critical behaviors that must be followed and build them into an observational checklist. If used with a number of employees, you could report percentage compliance for each behavior or overall. This approach could be modified by first determining the importance of each behavior (e.g., crucial, important, or recommended) and building this into the analysis. Since you are dealing with a finite number of employees, the analyses will be simple descriptive statistics such as frequency counts and proportions (or percentages). I hope this is helpful.
