A real life example then...
In AC Modelling we experience capacity problems from time to time. This is caused by two facts:
a) we cannot afford to resource up to the maximum we might ever need
b) it's a seasonal fluctuation, caused by quarterly sales targets
If a specific consultant's project is affected, than for that person this is something special. In the overall picture a capacity bottle neck is a normal occurence. If the consultant complains and escalates the problem, management will be tempted to "jump" on it. The modelling team then typically jumps into action, special arrangements are made, etc.. (remember last year's Marketing Mix crisis?)
This is "tampering". We are treating "common cause" as "special cause".
Ah, now this clarifies quite a bit the last post.
ReplyDeleteSo how to prevent the "tampering"? Get there first with a widescale forecast of the impending blizzard?
