Management oversight and risk tree MORT

A last reference here is the Guide to Use of the Management Oversight and Risk Tree (MORT). In the abstract for that publication, MORT is described as a comprehensive analytical procedure that provides a disciplined method for determining the systemic causes and contributing factors of accidents. This reference to performance errors is of particular interest.

In 1973 a revised management oversight and risk tree (MORT) manual was published by the AEC. Even though Johnson borrowed heavily from existing DOD and NASA programs, his MORT program bore little resemblance to programs based on MIL-STD-882 (Johnson 1973). 

Another major approach tends to be very different from other efforts described. The Department of Energy s approach is based on the management oversight and risk tree (MORT), a comprehensive, state-of-the-art program for safety management and system safety. 

The management oversight and risk tree (MORT) chart is a large, complex, negative tree (see Chapter 18). Even though the project evaluation tree (PET) is depicted as a positive tree, it is mentally converted and used as a fault tree for accident analysis applications (see Chapter 16). 

Change analysis is one of the techniques associated with the Department of Energy s management oversight and risk tree (MORT) approach to system safety. Unlike the MORT chart itself or some of the other tools and techniques associated with the MORT program, change analysis is a very simple, straightforward process that is relatively quick and easy to learn and to apply.

Another method closely related to system safety methods is Management Oversight and Risk Tree. MORT involves two items a diagram and a process. W. G. Johnson created the first MORT program in 1971 in the Department of Energy. 

Management Oversight and Risk Tree (MORT) Analysis is used to identify inadequacies in barriers and controls, specific barrier and support functions, and management functions. It identifies specific factors relating to an occurrence and identifies the management factors that permitted these... 

In MORT Safety Assurance Systems, WiUiam Johnson makes references to change analysis throughout the book as he discusses applying the Management Oversight and Risk Tree (MORT). Richard Stephens s System Safety for the 21st Century Contains a chapter titled Change Analysis. ...
