Generally, the management department is considered the most complex entity of a company because it defines the principles and objectives of a business, while functioning as a centralizing unit that sets into motion the whole job circuit PMP certification cost . When talking about projects (which have a determined start and completion date), the responsibilities of the project management seem to increase significantly because its main goals, which are scope, time and budget seem rather constraints.
Since the management of a project deals with key processes (such as coordination of human and physical resources, design and supervision of activities, optimization of inputs in accordance with the outputs, cost estimates, functionality of systems and work-flow, etc) a great deal of interest was set for facilitating and improving it. Thus, there is the traditional strategy which focuses on the stages of the project (that is initiation, planning, execution, monitoring and controlling, and finalization) and adopts a sequential approach reason why it is also called the waterfall model. Somehow conversely with this traditional strategy, the project-based management methodology emphasizes the significance of human interaction and malleability of processes for a successful managing.
Then, there is critical path which focuses on human and physical resources and the extreme project management that is designed for large projects, but lacks in process molding and human interface. Both strategies rely on the program evaluation and review technique which is rather appropriate for large-scale, non-recurring projects. The event chain methodology, as its name suggests emphasizes the recognition, classification and resolution of events and events ranges which may affect the schedule and cost of a project.
A more structured and comprehensive project management methodology is PRINCE 2. This strategy is based on the division of each process with specific objectives and activities into essential inputs and outputs. PRINCE2 mainly assists the organization of personnel and activities, offering insight in the design process and supervision methods, and also upholds control solution for schedule deviations.
