NETWORK ANALYSIS (PERT & CPM) It is a technique through which large projects are broken down to individual jobs or events and arranged in a logical network. PERT and CPM are two such network-based techniques designed to assist in the planning, scheduling, and control of projects. A project is defined as a collection of interrelated activities with each activity consuming time and resources. PERT: Program Evaluation and Review Technique CPM : Critical Path Method. Framework of PERT and CPM There

Until 1900, civil engineering projects were generally managed by creative architects, engineers, and master builders themselves, for example Vitruvius (first century BC), Christopher Wren (1632–1723), Thomas Telford(1757–1834) and Isambard Kingdom Brunel (1806–1859).[8] It was in the 1950s that organizations started to systematically apply project management tools and techniques to complex engineering projects.[9] Henry Gantt (1861–1919), the father of planning and control techniques As a discipline

1) Please identify the critical path using the activity letter provided and explain the significance of the critical path. The QSB output below shows the critical path. The path is significant because it demonstrates the path that is the most time consuming (longest to finish), as the activities on the critical path have no slack. The completion of each activity in this sequence is critical to the start of the next activity in the sequence. There is likely a “bottle neck” with one or more of these

tasks. One commonly-used technique is Program Evaluation Review Technique (PERT) which uses a detailed diagram of all anticipated tasks in a project, organised into a network to represent the dependence of each task on those that must precede it. PERT can be used to analyse the tasks involved in completing a project, especially the duration of each task, and identify the minimum time needed to complete the total project. PERT makes it possible to schedule a project without knowing the precise details
