Few project managers fails because they try a one-size-fits-all approach, they need to do different things, tailoring is a big key here, they need to distinguish between proactive and reactive actions, between extensive and minimum adjustment of tools and techniques and applying organization's culture, communicating with all stakeholders to ensure desired level of effectiveness to heads off problems before they occur.
Understanding the importance of accomplishing the scheduled tasks and solve urgent issues before they became emergencies.
That can be achieved by making several adjustment to the leverage of planning on team members, materials, through out the stages of the project with continuous verification.
