Proactive project management is often the most influential factor in having a successful project. It is necessary to complete a project under budget, creating a sustainable team culture, and maintaining long term customer.
Your unsuccessful projects in the past may have been due to lack of experience, wrong/missing equipment, contractor mistakes, difficult customers, or a variety of other issues. In each of these scenarios, there is something that could have been done ahead of time to address the issue. This ability to proactively identify future issues will define the eventual success for your project.
