“Project Management is the discipline of organizing and managing resources (e.g. people) in such a way that the project is completed within defined scope, quality, time and cost constraints. A project is a temporary and one-time endeavor undertaken to create a unique product or service, which brings about beneficial change or added value.” 
The goal of software project management is to understand, plan, measure and control the project such that it is delivered on time and on budget. This involves gathering requirements, managing risk, monitoring and controlling progress, and following a software development process.
Software project management requires trained and experienced Software Engineers in order to increase the likelihood of project success because software development for large projects is extremely complex and following strict engineering principles will help reduce the risks associated with the project.
