I have found an interesting video post from 4 PM wesbite about the challenges of persuading a sponsor that project planning is worthwhile
The post says…”One of the very difficult barriers to doing projects the right way is the reluctance of sponsors and stakeholders to participate in the planning process. Its much easier for them to avoid making the the tough decisions that should be made at the beginning of a project. Project managers have to muster effective arguments or they wind up starting work without a plan which is the seed of project failure.”
