Name & Logo Information - from Kelvin TOP-SET®

The Kelvin TOP-SET® logo represents a mathematical set, and relates to the systems thinking that underpins the TOP-SET® methodology.

The TOP-SET® methodology classifies Time - T, Organisation - O, People - P, Similar Events - S, Environmental - E, Technical - T as separate systems, and an incident investigator using TOP-SET® should search for evidence in each of these areas.

Of course, these systems interrelate, and an event that occurs in one area will have repercussions in another. After as much evidence as possible has been found to provide a picture of the incident, an analysis of the causal links between events is undertaken, using the method of root cause analysis, to clearly explain what happened.
