You have my deepest sympathies, although it is encouraging to note that your company has identified this as an issue.
I think the risk here is that a little knowledge can be a dangerous thing in a project manager's hands. It is not unusual for project managers with a small amount of technical knowledge to make engineering decisions without understanding the full implications. Given that, my felling is that the training needs to be 'top down', staring with training in engineering management and R&D management and working down to technical detail - in other words the exactly opposite sequence to the way that engineers are trained. That way the issues of risk and change management are hopefully made clear at the outset.
That said, I agree that most engineering management courses around are focussing on detailed project or maybe personnel management rather than management of the engineering process which would be of more value here, if anyone else can suggest one I might go on it myself!
