Process Efficiency Assessment

Common and special causes are the two distinct origins of variation in a process, as defined by W. Edwards Deming. "Common causes" are the usual, historical, quantifiable variation in a system, while "special causes" are unusual, not previously observed, non-quantifiable variation.

Most of the time, organization efficiency and effectiveness is caused by "special causes" and it is characterized by: 

* new, unanticipated, emergent or previously neglected phenomena within the operation
* variation inherently unpredictable
* variation outside the historical experience base
* it can be know or un-known.  If it is known causes, they are perceived as difficult or impossible to fix ​

Common example of Special causes can be found in Hong Kong Operation
* poor adjustment of equipment
* human errors in non-standard operations
* process flow​ build-in logic error

* hidden non-value added steps
* missing of self-monitoring mechanism
* etc.

Process Efficiency Assessment is the introduction of 3rd party process​​ health check.  Organization and process owners can maintain continuous diagnosis of their process efficiency and effectiveness.
