Every project needs a plan before it begins. A blueprint or summary per se to provide a clear track to run on.
With larger, more complex projects, a project scope document is required to outline the project prior to the building process. The scope helps in identifying your goals, objectives, tasks, resources, budget, and scheduling. Defining the project scope outlines the parameters or limitations of the project and spells out what is expected by all parties in the form of communications, deliverables, and more. It not only acts a measurement tool for success, but provides a clear understanding to all parties of what the project will entail.
