    Planning is an important phase in project management. One may have an excellent design but without noting down the budget and other constraints, it may not become materialized. The planning process is a guide to project control and execution and it enables communication between the people involved in the project. The plan describes how the project is going to be started, managed, executed and controlled. It also outlines the persons who are responsible for certain tasks. The goals are outlined so that they serve as the basis on how to start the project. Strategies for the tasks are going to be listed and chosen and statement of project scope is also done. After all these, a detailed implementation plan is going to be developed and signed by the project stakeholders.

    Careful planning will incorporate the design and analysis phase and once the plan is ready, it will be easy to facilitate product design while analysis will systematically occur. Planning is the foundation of every project.

If design comes ahead of planning, there is no proper assignment of tasks and duties which might leave others ...
