Here are the 4 terms frequently used by executives to hide the fact that they are not able to define what they precisely expect from an ERP: cost, strategy,
productivity and communication.Those terms are forbidden subjects in this lecture.
In other contexts, they could be useful terms. But here, they are reallly not.
For example, caring too much about specific way of computing a cost will have no impact on being able to deliver products in time. Cost does not even have any impact on cash, except very indirectly through the ability to obtain
a bank loan by producing financial reports based on a cost formula that maximises EBITDA. This is not the role of an ERP, but of an external reporting system. This external
reporting system needs nothing else but accurate data extracted from the ERP.
About strategy, executives often mention this word to hide the fact that they have no actual priorities for their ERP implementation.
Productivity - sometimes mentioned as efficient user interface - is also a way to escape from defining clear goals in terms of quantitative management. Real productivty derives
from automation: an executive who has clear goals with thus explain how he plans to change organisation with the ERP and which part can be automated.
Communication is the last forbidden word. It refers often to the idea of the right information at the right time - which is not a bad idea - but it can only be achieved
in an ERP and possibly with any management software by defining organisation processes of which the side effect is to bring that right information at the right time to the right person.
We thus forbid this work too in order to ensure that executives define that organisation process.
