Project Management

Step 1: Understand the nature of the options provided. Step 1: The options listed (Planning, Organising, Scheduling, Controlling) are functions of project management. While PERT is a specific tool used within project management, especially for scheduling, the question presents these broader management steps. We need to arrange them in their logical flow.
Step 2: Arrange the management functions logically.
Step 2: The standard sequence of management functions in a project life cycle is:

(A) Planning: The first phase involves defining goals, specifying tasks, and determining the resources needed.
(B) Organising: This involves arranging resources, defining roles and responsibilities, and structuring the project team.
(C) Scheduling: This is the process of creating a timeline for the project tasks. This is where a tool like PERT would be specifically used to create a network diagram and determine the critical path.
(D) Coordinating and Controlling: This is the execution and monitoring phase, where progress is tracked against the plan and schedule, and corrective actions are taken.
Step 3: Conclude the correct order.
Step 3: The logical progression of these management activities is A B C D.
