CPM
The critical path method (CPM): As applied to construction projects
The critical path method (CPM) was originally developed by the DuPont Company in the 1950s as a method of project management when DuPont shutting down its chemical plants for maintenance work. The shutdown process was complex and detailed, and had to be deployed in a highly regimented fashion in terms of the completion of steps and coordination of the workforce (CPM, 2011, Net MBA). Yet the process also demanded a certain amount of flexibility in terms of managing unexpected delays, as well as the need to reduce costs. Ever since its inception, other companies have been using the CPM method to optimize efficiency and reduce costs. Now it is most often used in the construction, architectural, and engineering industries to manage a project with multiple components.
The method is graphical in nature and thus is ideal to deploy for a multi-stage project. "CPM models the activities and events of a project as a network. Activities are depicted as nodes on the network and events that signify the beginning or ending of activities are depicted as arcs or lines between the nodes" (CPM, 2011, Net MBA). At the beginning of the CPM process, project managers specify the individual activities they must perform to ensure the project's completion, sequence these activities, and create a diagram with an estimation of the overall completion time. Then they identify the 'critical path' or the longest time that will be needed to complete...
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
2002). This paper's focus will be on the CPM and PERT methodologies. The Rockfest event has 26 tasks, each conveniently denoted by a letter in the alphabet. 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
Project Management Plan of a New Restaurant This project management plan is majorly concerned primarily with the first two steps which are defining the project; the project objective is broken down into a series of manageable steps called tasks and designing the project process; this work is performed by the project manager and is presented in the GANTT chart where the tasks are displayed in more detail (Hamilton, 2004). Besides, for
Project Management Project Information, History, Intent, and Life Cycle Gray and Larson, (2008) define project as "a temporary endeavor undertaken to create a unique product, service, or result." (p 5). Essential feature of a project is that it has a defined beginning and end often subject to time or fund constraint to achieve stakeholder's goals and objectives. Gray and Larson (2008) differentiate between project and program. "A program is a group of
(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
Project Management Explain the differences between Activity-on-node and Activity-on-Arrow in developing the project network. They are both flow charts that set out to show the order in which a project's activities are meant to be completed. Activity on node uses nodes to illustrate activities. Activity on arrow uses arrows to illustrate activities. There are differences between the two project networks. First, Activity on node networks mainly focuses on tasks (milestones) while activity
