Element element element element element what should be investigated?

Post investigation
After the investigation has concluded, it is particularly important that the findings of the investigation are communicated to all 
the relevant people. It is important that the organisation learns lessons from the incident. It is also imperative that:
y
the controls implemented are analysed to determine their effectiveness; and
y
witnesses and casualties are supported through any trauma they may have experienced.
If the incident had serious consequences, then access to the scene will usually be restricted to the investigation team plus other 
third parties, eg unions and enforcement authorities. Once the investigation has been completed, the investigation team should 
formally release the scene back to the operational unit as soon as is reasonably possible. This will allow ‘business as usual’ to 
recommence.

y
Closure.
y
Evaluation. 
This chapter will take students through each stage and explain what is required to make your interviews successful.
The final section of the chapter will deal with barriers to good interviews, dealing with reluctant witnesses, blame culture and 
how this could affect interviews and, finally, three types of bias which could affect the outcome of an investigation.
