Evidence based management Vis A Vis Facts based Management

Dear Sergio
I have not stated "ensure" but stated "assure" In assurance there is no 100% certainty but aim is that. ( assurance can be 90% for example)
Any way my point is Evidence is needed for proving that the said fact is not perceived fact but a solid fact at a point of reference based on evidence.
Fact has a dimension of time and hence evidence is needed.
Certain data has evidence and based on that evidential data if certain empirical relation is adopted without it's validation at a future date of use can lead to wrong assumption and hence wrong results.
Another important point from end is management involves decision making consumimg resources of some body ,so for proving that the decisions made were fact based evidence is needed. This is another dimension of evidence based management. Todays factual event can have have some consequence while the same factual event happening in future may have all together different consequence ,hence the concern

In my limited English "assure" is "make (something) certain to happen" . Evidence/Fact Based management is not a matter of perception. And it is not a matter of data, is a matter of information. But this topic is easy to understand going to scientific method utilization and understanding then right tools are using to deal with that. In my example above, we used Z language for requirements specification. But the point is: could Z language be used for all types of software creation? Not at all because the cost of using it (mainly for time spent on specifications and the learning curve and expertisse needed to use it) does not justify for software that do not have the inherent risk I mentioned above. The same with Evidence/Fact Management.

Dear Sergio
Thanks a lot for your inputs
