Your answer is clear.
Your report states that 71% of the contracts awarded to McKinsey were awarded non-competitively. This means that 29% were awarded competitively.
However, even in cases where so-called competitive contracts were awarded, the processes were sometimes not fully competitive, to the extent that the selection criteria were sometimes too restrictive, which you noted in your report.
In the case of contracts awarded non-competitively, only a small proportion—around 20% of the contracts awarded to McKinsey—were on a standing offer. Thus, 50% of the contracts awarded to McKinsey were awarded non-competitively, and there were no standing offers. Even when a standing offer was put in place, it was done following a non-competitive process.
