When you plan for a work then the work becomes Easier. Suppose you have a project to complete in your workplace, you are the team leader and you have not planned for it, but you have decided to start the project from a particular date and end it on another date. You have also told the team members to start the project from the same day and nothing else. Then, in this case, nobody actually knows where to start, what part to do and what not to. In this scenario, the chances of making mistakes are more, and the project may exceed the target date.

Now, let us assume that you have planned for the project. Then, you know that which person has to work on which part of the project. Now, every team member knows how to divide his/her time to complete his/her part of work and the chances of committing mistakes are less.
