Does PMWar portal has a wrong question and incorrect answer on "ControlLimits"?

hello Arvind,
first of all consider I'm Italian speaking so, probably, my English translation couldn't be the correct one.the first concept we have to consider is that specific limits (defined by the tolerance) have not statistical or mathematical relation with control limits. these last ones can be defined in different ways (for instance, we have control chart where the control limits are defined on the basis of 3 sigma or, in other cases, on the basis of the probability -I don't know if this is the correct translation - this last system is more used in Europe).
In other word we can define the control limits in accordance with:
a) our needs
b) the characteristics of the process we are analyzing
This is the reason because i affirm that the control limits SHOULD be defined by experts (has the PM or "normal" stakeholder the knowledge for doing it?).
Literature: I cannot suggest to you any literature in English because the documents I learnt are in Italian.
The second sentence was not deducted by the question but it was only an example.
many thanks for your suggestion

Hello Arvind,

thx for your response. Like i said, i am no expert in statisticly theorys and/or processes ... for me, while i am laerning for PMP and also in daily practice it was totally clear and plausibel, that the control charts and its values where defined by the experts and than adjust along the process baes on the upcoming results.
If you that convinced, that PMBoK Guide and PMI is wrong here, well than you may should contact the team what is actually working on the PMBoK Guide 6th edition and make a suggestion for correction.

Hello Rami,

Thanks for ur response. I agree with everything that you wrote in your explanation but that still does NOT make C as the correct answer. Pl see my explanation above.

Thanks.

Arvind

PMI ,as far as I am aware, defines a Stakeholder as anyone involved in the project directly or indirectly even the public so team members are included under stakeholders as well as the project manager because at some point he can be on a part-time basis in a matrix or functional organization so I believe the correct Answer is "C".
