Critical Path Analysis

A technique widely used by the industry is Critical Path Analysis (CPA or Network Analysis ) which is a method for systematically analysing the schedule of large projects, so that activities within a project can be phased logically, and dependencies identified. All activities are given a duration and the longest route through the network is known as the critical path.

Most detailed programs for plant-related projects are prepared using simple critical path analysis (CPA) techniques. CPA is a well-known and familiar technique to most engineers and is incorporated into most modern PC-based planning and scheduling systems. Such a system typically has the following features that a plant project manager will find useful ... 

In order to make the best possible use of valuable financial and other resources, and to minimise the uncertainty involved in making irreversible decisions, appraisal techniques are vitally important. These can be technical, legal, regulatory, commercial or financial in nature, for instance market forecasting and patent protection. Critical path analysis is... 

We need to set up a network or arrow diagram based on a Critical Path Analysis of all the factors and activities which relate to coal mining and determine in a quantitative way what is required and what specifically has to be done and by whom in order to achieve a coal production level of 1 billion tons per year. 

We need to use the Critical Path Analysis in order to determine what work has to be done before other activities can be started and how all the activities related to each other. 

If one wants to plan and control a larger project in a serious manner, project management software packages are essential and save a lot of time. These programs use entry data such as task descriptions, their duration, start or finish times, tasks dependencies and milestones to automatically sequence and schedule the project tasks. Conflicts and logic errors are identified and the project is re-scheduled after these have been corrected. A critical path analysis function reveals and... 

Decentralization— making divisions more independent. Flat Organizations—eliminate middle management. Critical Path Analysis—studying general procedures. Sales Force Automation—computerizing the sales force. 

Finally, no management system can be considered without the support of a planning operation with various types of bar charts, PERT (Program Evaluation and Review Technique) charts and full critical path analysis. Although these systems are a useful tool for management, occasionally there is a risk that the system takes over management.

Resource loading follows the critical path analysis. Resource loading specifies the resources that will be needed for each planning period (typically one week) on the project timeline. The benefit of resource loading is that it identifies conflicts in the schedule (i.e., resources assigned to different... 

The order of individual steps in the table does not necessarily mean a chronological order. Generally, according to a time schedule (critical path analysis, Gantt plan) steps are carried out in parallel as much as possible. 

The flow diagram given in Figure 2 can be used as an aid in relating data requirements and critical path analysis to overall program planning. 

UPDATING A CRITICAL PATH ANALYSIS The purpose of this exercise is to gain practice in updating a CPM analysis as would be done once a project is underway. Suggested tasks are ... 

There are no changes in the job logic, that is, in the number of tasks and their interrelationships. However, such changes could very easily have arisen at this stage in the project and would have to be reflected in the updated critical path analysis. 

Critical path analysis and programme evaluation and review techniques are examples of project network techniques. 

Critical path analysis identifies critical paths in a program evaluation graphical network.
