The Institution of Diagnostic Engineers (affectionately known worldwide as DIAGS) was founded in April 1981 by the late Dr. Ralph Collacott.

We define the role of a diagnostic engineer as any person capable of contributing to the art or science of determining the existence of a problem in a machine, plant, system, or structure and/or appraising the cause(s) of a failure, which may have taken place and/or assessing the condition or vulnerability of such machine, plant, system or structure either during use or while under development.

It is accepted that through a diagnostic capability or a special knowledge of a failure and deterioration modes, reliabilities and hazards a person will be able to contribute to a satisfactory assessment of the causes of a defect and able to contribute to the identification of remedial action to cure the defect and prevent failure.
