Critical Path Method (CPM) and Critical Chain Method (CCM). How is CCM an improvement over CPM?
The Concepts
The concept of paths and the slacks on the path have been around the management circles from the 1960s, with the concept of slack being defined as the amount of time an activity on a production line can be halted without affecting the project completion date. (Hansen, 1964) Likewise the critical path and the critical management of work flow are not new concepts. However the way they come to be viewed are new. The project planning begins with the concept of what is to be achieved, how it will be achieved and the time and method that will be used in completing the project. There are many variables that are to be considered that include dependence is, slack and the work flow and allocation of work and the performance appraisal. It also involves analysis of the slack time, and the way the work has bottle necks or dependencies.
This network of diagrams is based on the activity and the critical time involved in the completion. The critical path method uses the network diagram to split up the work in terms of modules indicating the flow of work through the network and the duration. Thus there can be parallel activities through two paths that end in creating a unit of turnout, or independently proceed to the goal. There could be smaller paths that are interconnected such that the performance of one precedes the other. This is to...
The making of the critical path plan is the first step to create synergy between the various participants and for anticipating resistance and delay. (Schwalbe, 2006)
The critical path method is a system that can be a graphical model of work flow with anticipation of the interdependencies. The critical path methods have representations in a graphic form that can be a map on paper of the actual method of allotting work and the process of work flow. The disadvantages are that the diagrams are mostly stipulated but not often pragmatic and there are issues where situations that are frequently encountered are clumsier to represent and the critical path suffers from the flaw of non-representations of these events. It thus cannot show the elimination of activities that may not be necessary or useful. It is useful in eliminating noon critical activities and keeping the unit to the critical activities. (Schwalbe, 2006)
The critical chain method incorporates the allocation of resources in the system and thus is superior than the critical path because of the reasons that in the critical chain method not only are the scheduled allotted as per the system of the critical…

Having drawn up the Critical Path and analyzed it, I found the following. The Critical Path starts with task A, continues with B, D, E, F, G, and finally O. The time it takes to complete these tasks is 34 weeks. That is
CPM is critically important from a supply chain management standpoint in optimizing inventory positions by location throughout a distribution channel as well (Omar, 2009). All of these factors contribute to the automating of CPM and PERT through organizations who are heavily reliant on their supply chains to gain a competitive advantage. The optimization of inventory workflows using CPM and PERT contribute to that competitive advantage over time. PERT and
GANTT and PERT Chart Tools "One look is worth a thousand words" (Barnard, 1920s, as cited in Lutz, 2009, p. 7). Critical Chart Choices Just as the project manager must evaluate alignment, benefits, and risks as well as other business and project factors when considering projects to manage, the project manager must also routinely make critical chart choices. During the course of a project, the project manager must assess whether GANTT charts, critical
(Braunschweig; Day, 150) Most of the current generation of project managers expects the project management tools to furnish them with almost real-time knowledge in order to facilitate their decision-making. Some of these tools like DOFF, "Field of the Future," "Smart Fields," Microsoft's "Oilfield Connectivity" and i-Fields are currently being examined by exploration and production oil companies. Some of these tools have the capability of generating information from apparently incongruent data
Operations Management Report -- Community Bank of Perth The Community Bank of Perth has experienced tremendous growth in home loan refinancing in the past two years. This is due in part to continued growth of the Western Australian mining sector, as well as increased consumer interest in more innovative and economical loan terms. With rising competition in the market, more lenders are now aggressively working to boost their market share through
