Q13 Can
Six-Sigma removes causes of human error?
|
Application of the DMAIC principle can and does remove
some contributory causes of error but not all, for a least two reasons.
Firstly, six-sigma prioritises and analyses processes that have been
troublesome in past and therefore does not address causal factors in those with
no or low incidence of historic failure. However,
many of these factors are shared by many processes so that their combined
adverse effects have a high probability of resulting in error somewhere, perhaps
without precedent. Secondly, the
probabilistic nature of many cognitive processes implicated in human error is
not addressed in the usual application of six-sigma.
