I'll just clarify the percentage issue.
We used a sample consisting of 33 contracts out of the 97 contracts in question. This was a sampling for statistical purposes.
Indeed, you could extrapolate from professional services contracts. That said, I think it is important to make it clear that comparisons should be made based on the same population.
So, 58% of contracts had one or more shortcomings. In 85% of cases, there was a missing explanation, namely why the contract had been awarded.
I know I'm talking a lot about percentages, but I think it's important to clarify things. More than half of the contracts had one or more issues, making it impossible for us to determine whether value had actually been received in relation to funds spent.
