Well, the number of military procurement personnel at DND and PSPC is certainly one factor explaining the delay in procuring some major equipment, but it's not the only one. Increasing the number of procurement personnel is probably necessary, I think, but it may not be sufficient in ensuring that the pieces of equipment that DND needs for its forces would be procured on time and within budget.
It's necessary but probably not sufficient. There are other issues at play, such as the capacity in Canada for domestic production, for example.
