Projects and managing them have always been considered a subject worth studying. The formalized form of project management is not as old as many other branches of industrial engineering, however, the progress that has been observed through innumerable reviews and research findings is extraordinary and outstanding. The matter of interest for this paper is to initiate discussion regarding simplifying the tools and methods for managing projects and begin an era of simplification by discouraging practices that make project management a harder job to perform and a tougher task to handle. Besides summarizing the definitions of “project” that have been found from reviewing the relevant text, it deliberates on revising the duties and responsibilities of project manager and proposes performance expectancy triangle. It sheds light on several factors that have been found critical to the success and failure of projects. Also, it proposes a function indicating that customer needs and demands or desires greatly affect and instigate project complexity.
