Criticalchainprojectmanagement — Document Transcript †¢ 1. Critical Path Method and Critical Chain Project ManagementProject schedule plan is the main plan included in any Project Management Plan. Project schedule isresponsible for bringing project time, cost and quality under control. Project schedule links resources,tasks and time line together. Once a Project Manager has list of resources, work breakdown structure(WBS) and effort estimates, he is good to go for planning project schedule. Schedule networkanalysis helps Project Manager to prevent undesirable risks involved in the project. Critical PathMethod (CPM) and Critical Chain Project Management (CCPM) are key elements of schedule networkanalysis. In the following sections we will†¦show more content†¦Ã¢â‚¬ ¢ 3. CCPM is based on:- Resource constrained situations.- Optimum use of Buffer (amount of time added to any task to prevent slippage of schedule) o Project Buffers (PB): Amount of buffer time at the end of the project. o Feeding Buffers (FB): Amount of buffer t ime at the end of a sequence of tasks. o Resource Buffers (RB): It is an alert that is used to indicate that resource is needed to perform a task. This alert can be set few days before a resource is actually needed.CCPM Example:We will consider the same example that was explained in section Critical Path Method Example.CCPM can be applied using following three steps:1. Remove safety time and reduce tasks durations by 50%.Project Duration = Task1+Task2+Task3+ Task6 = 3+2+1+4 = 10 Days.Note:†¢ All safety time durations are removed. For example 1 day lag after Task 2 and 4 days after Task5 are removed.†¢ All tasks durations are reduced to half (50%). For example Task 1 is 3 Days instead of 6 days.2. Create schedule on Late Finish dates and Remove resource constraints and identify critical chain.Project Duration = Task1+Task2+Task5+ Task6 = 3+2+2+4 = 11 Days.Note:†¢ Task3, Task4 and Task 5 are moved to start from Late Finish dates.†¢ Task2 and Task5 are to be done by resource R2 and so that aligned to remove resource constraints. †¢ 4. 3. Add Project Buffer of 50% of the tasks duration and add Feeder buffer to non critical chain.Project Duration = Task1+Task2+Task5+ Task6 + PBShow MoreRelatedA Critique of the Critical Chain Approach to Project Management3777 Words   |  16 PagesCourse in Operations Management ASSIGNMENT 1: â€Å"A CRITIQUE OF THE CRITICAL CHAIN APPROACH TO PROJECT MANAGEMENT† 3,000 words excluding reference list and summary for Dr. Tom Mullen Anthony C Mould October 2003 Reprinted with the kind permission of Anthony C Moulds.

Lennon Module V 11.17.12 Abstract Project managers carefully manage slack on sensitive resource-limited projects (Larson and Gray, p.295). If possible, they will add slack at the end of the project by committing to a completion date that goes beyond the scheduled date. Eliyahu Goldratt (1997) advocates an alternative approach to managing slack. He championed the â€Å"theory of constraints† and has coined the term â€Å"critical-chain† recognizingRead MoreCritical Chain By Dr. Eliyahu Goldratt1348 Words   |  6 PagesSummary of Critical Chain novel Critical Chain is a novel that wrote by Dr. Eliyahu Goldratt. In the Novel, he used novel mode to describe that how to use Critical Chain Theory to fix manage problem. Specially, he used common sense and logical deduction to give us a clearly description about the complex manage problems. This special is interested me a lot that attract me to fail into the story that can follow Dr. Goldratt’s ideas. In the book, Dr. Goldratt talks about how a professor trying to attainRead MoreUnderstanding Project Management Related Approaches1324 Words   |  6 PagesUnderstanding Project Management Related Approaches Chandra Shekar Pulipati Oklahoma State University Abstract Several approaches exist towards a successful project management. These have been emerging over years and also vary from project to project and industry to industry. This article focuses on few of popular project management techniques 1. PRINCE2 (Projects in Controlled Environments) 2. CPPM (Critical chain project management) 3. Agile Project Management Each of this technique focuses onRead MoreCritical Chain, By Eli Goldratt Essay1728 Words   |  7 Pagescommon mismanagement of projects. In response, many approaches to project management have been developed in order to mitigate the adverse effects of the inevitable ambiguity. However, many of these methods fail to address erroneous assumptions that are often made at the management level. In the novel â€Å"Critical Chain†, Eli Goldratt presents effective methods that challenge such assumptions. The novel follows multiple stories in order to demonstrate the benefits of this management philosophy as they applyRead MoreProject Management Scheduling1657 Words   |  7 PagesTitle Successful Project Management Scheduling outcomes: A Theoretical Comparative Analysis of networking techniques between Event, Chain with other traditional methodologies Research Question Why it is important to conduct a comparative analysis of Event, Chain with other traditional methodologies and investigate how it contributes in being Successful scheduling techniques in Project Management discipline?

How do they differ? Critical path and critical chain are both schedule network analysis techniques. Critical path is the one that determines the shortest time to complete a project, which assumes low uncertainty and does not consider resource dependencies. Critical chain is a modified or refined technique about critical path; it involves the deterministic and probabilistic approaches to analyze the project schedule, which is moreRead MoreExam Summary949 Words   |  4 Pagesthe impacts on organisation 4.)
