Project planning is the critical aspect of any project. With continuous advancements and time demands in today's business world, there may be a temptation to get started on a project without considering where it will lead. The greatest danger in doing this is misunderstandings between stakeholders, which arise from diffrences in expectations. Planning helps you to form ideas and to discover where the project needs to go and the best way to get there in the allotted time.
Evenif good planning is helping you within project execution, still there are many things out of control, why? Planning is a thinking way, instead of a method or technology.
