Apart from quality of evidence and its analysis, the quality of investigation consists of how the investigation process responds to the needs, its timeliness, and the amount of disruption to the normal organizational work.
Trained, seasoned investigator has experience and insight to define an efficient work plan to obtain sufficient evidence with a minimum fuss. Whilst analysis of documental evidence requires ability to pinpoint details and inconsistencies, efficient interviewing requires human skills and ability to connect. Experienced investigator has also ability to realize weaknesses and possibly false statements. They are able to handle scared and vulnerable witnesses and understand how the stress may affect to the perception and the memory.
Sometimes the subject of investigation becomes aggressive during the interview and an experienced investigator has skills to deflate the situation.

Every investigation is conducted in unified manner, enabling equal treatment of staff and unified responses to the substantiated misconducts.
