Most companies are complaining of insufficient resources for the wrong reasons (I believe having more ideas and initiatives and hence no resources is a good scenario)
People want to do things fast (or atleast think they can) by short cutting processes. Poor process adherence (in intent) leads to poor quality and capability build up. This results in fires. Fires result in a surge in resource requirements. Sudden surges cant be met with external resources. They are met by redeployment from other processes and projects. By the time the problem is fixes, the other processes with poor resources are way behind schedules resulting in people want to things faster! - Indeed a fantastic negative spiral!
Further, in the long run, poor process adherence leads to no metrics and continuous improvement. Resulting in poor capability buildup (and inflexibility). This results in poor business efficiencies and results. This leads to fires and patchwork.
This is probably the only real reason to create and execute to processes even at the risk of first time being a little late - The net result will always be better than getting into the negative spiral
