What are the benefits of careful planning to the project manager?

Projects are always one-of-a-kind undertakings. Anything that is routine does not fall under project management. Often nobody exactly knows what needs to be done prior to execution. Thorough planning is needed to reduce much of the uncertainty surrounding the execution of the project. Some projects are small and relatively simple while others are very large and complex. Especially in these large and complex projects there are many tasks that depend on each other. For example, you first need to pour the foundation of your house before you can build the walls. Careful planning is needed to execute the project tasks in the correct order and to make sure they are performed on time to minimize waiting time and resulting cost overruns. You do not want your drywall crew to wait around while the electrician finishes up his work. A waiting crew costs money and is not productive. To avoid these kinds of mishaps you need to think hard and thorough about how you are going to execute a project. Careful planning will safe money and immensely improve the chance that that your project finishes on time and within budget. If you do not feel comfortable about preparing such a planning yourself get an expert involved. The money you pay for the expert advice is many times over recovered during the execution because you spare yourself delays and unexpected costs due to poor planning.
