Project Manager is responsible for meeting project goals, for budgets, schedules, for assessing risks and deciding how to avoid, accept, mitigate them, and for leading the project to successful completion (DiVincenzo, 2006).The project manager is not the only person responsible for management of the project it takes a team to deliver a project successfully. For example, manager depends on the engineers responsible for delivering the expected product on schedule. Hence despite putting a project manager in the role does not ensure project success. Effective project managers must interact with various user and stakeholders inside and out of the organization, with conflicting interests relevant to the current project. (Zielinski, 2005) Stated that project managers must simultaneously satisfy the needs of users, stick to tight deadlines, and limited or sometimes no resources to do the job all while motivating diverse group of personalities in the project. Responsibility without authority is another challenge for project managers; they have little authority over the team that might be difficult to exert influence over the team. (Baca, 2007) ,(Wellman, 2007) States that engineers who are in the role of project managers often concentrate on technical issues while giving management aspect less importance. There continues a difference of opinion on what factors determine an effective project manager some suggest technical expertise is a major factor; some suggest soft skills is the primary factor, and others suggest that both soft skills and technical skills are both the determinants of project success. (DROSSEL, 1980) States that technical and leadership skills are of the same importance while (ZACHARY, 1984) suggest that balance between both the skills is necessary. It is evident that technical skills are not the only factor of effective project management so, technical skills along with soft skills, well training and strong educational background are necessary for effective project management.
