For all of their effort, they seemed unwilling to grasp how their choices of process and conditions were making it impossible to obtain meaningful information. Even if all went well, the first few data collections are plagued with errors, personnel aren't clear what you are asking of them or are afraid to give it to you. As for interpretation: You don't have a baseline to compare them to (is that 7 in indicador 3 good or bad?) and you don't have a tendency (is it improving or getting worse, is more better or worse?).
How do you know if your expectations are too much? Read their body language! If you see:
- Uncomfortable smiles
- Weight shifting
- Darting eyes - nobody looks at you in the eyes but look at each other worriedly
The point here is that you have to be realistic on your expectations - if you ask for the impossible again and again you will lose credibility - the result is that nobody takes him seriously anymore and the work they do produce is more made up than a ride at Disney.
