The 10 project management knowledge areas from PMBOK are discussed as follows:
1. Project Schedule Management:
Project schedule management is the process of comparing actual schedule performance to the baseline schedule to determine variances, evaluate possible alternatives, and take the appropriate action (Richman, 2011). It includes the processes required to manage the timely completion of a project. The project scheduling provides a detailed plan that represents how and when the project will deliver the products, services, and results defined in the project scope and serves as a tool for communication stakeholders’ expectations, and as a basis for performance reporting (PMI, 2017). According to the PMBOK, the project schedule management includes the following process:
? Planning schedule management: is the process of establishing the policies, procedures, and documentation for planning, developing, managing, executing, and controlling the project schedule.
Defining activities: is the process of identifying and documenting the specific actions to be performed to produce the project deliverables.
Sequencing activities: is the process of identifying and documenting relationships among the project activities.
Estimating activity duration: is the process of estimating the number of work periods needed to complete individual activities with the estimated resources.
Developing schedule: is the process of analyzing activity sequences, durations, resource requirements, and schedule constraints to create the project schedule model for project execution and monitoring and controlling.
Controlling schedule: is the process of monitoring the status of the project to update the project schedule and manage changes to the schedule baseline.
