Critical Chain
Critical chain project management (CCPM) is a method of planning and managing projects that emphasizes the resources (people, equipment, physical space) required to execute project tasks. It was developed by Eliyahu M. Goldratt. It differs from more traditional methods that derive from critical path and PERT algorithms, which emphasize task order and rigid scheduling. A critical chain project network strives to keep resources levelled, and requires that they be flexible in start times. Origins Critical chain project management is based on methods and algorithms derived from Theory of Constraints. The idea of CCPM was introduced in 1997 in Eliyahu M. Goldratt's book, ''Critical Chain''. The application of CCPM has been credited with achieving projects 10% to 50% faster and/or cheaper than the traditional methods (i.e., CPM, PERT, Gantt, etc.) developed from 1910 to 1950s. According to studies of traditional project management methods by Standish Group and others as of 1 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Project Management
Project management is the process of leading the work of a team to achieve all project goals within the given constraints. This information is usually described in project documentation, created at the beginning of the development process. The primary constraints are scope, time, and budget. The secondary challenge is to optimize the allocation of necessary inputs and apply them to meet pre-defined objectives. The objective of project management is to produce a complete project which complies with the client's objectives. In many cases, the objective of project management is also to shape or reform the client's brief to feasibly address the client's objectives. Once the client's objectives are clearly established, they should influence all decisions made by other people involved in the project – for example, project managers, designers, contractors, and subcontractors. Ill-defined or too tightly prescribed project management objectives are detrimental to decision-maki ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Project Stakeholders
Project stakeholders are persons or entities who have an interest in a given project. According to the Project Management Institute (PMI), the term ''project stakeholder'' refers to "an individual, group, or organization, who may affect, be affected by, or perceive itself to be affected by a decision, activity, or outcome of a project". ISO 21500 uses a similar definition. Stakeholders may be located inside or outside an organization, including: # the project's sponsor; # those with an interest or the potential to gain from the successful completion of a project; #anyone who may have a positive or negative influence in the project completion. Example roles The following are examples of project stakeholders: * Project leader * Senior management * Project team members * Project customer * Resource managers * Line managers * Product user group * Project testers * Any group impacted by the project as it progresses * Any group impacted by the project when it is completed * Subcontracto ...

Student Syndrome
''Student syndrome'' refers to planned procrastination, when, for example, a student will only start to apply themselves to an assignment at the last possible moment before its deadline. This eliminates any potential safety margins and puts the person under stress and pressure. According to one academic source, it is done in order to induce a level of urgency high enough to ensure the proper amount of effort is put into the task. The term is used to describe this form of procrastination in general, and not only by students. For example, in the field of software engineering: "This initial research investigates three behavioral issues which may affect team member productivity in both a traditional waterfall project and in a Scrum project: the management of stress, the use of slack and the student syndrome." The term is said to have been introduced by Eliyahu M. Goldratt in his novel ''Critical Chain''. See also * Cramming (education) * Hofstadter's law * Parkinson's law * Pyg ...

Work Breakdown Structure
A work-breakdown structure (WBS) in project management and systems engineering is a deliverable-oriented breakdown of a project into smaller components. A work breakdown structure is a key project deliverable that organizes the team's work into manageable sections. The Project Management Body of Knowledge (PMBOK 5) defines the work-breakdown structure as a "hierarchical decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and create the required deliverables." A work-breakdown structure element may be a product, data, service, or any combination of these. A WBS also provides the necessary framework for detailed cost estimation and control while providing guidance for schedule development and control.Booz, Allen & HamiltoEarned Value Management Tutorial Module 2: Work Breakdown Structure [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Event Chain Methodology
Event chain methodology is a network analysis technique that is focused on identifying and managing events and relationship between them (event chains) that affect project schedules. It is an uncertainty modeling schedule technique. Event chain methodology is an extension of quantitative project risk analysis with Monte Carlo simulations. It is the next advance beyond critical path method and critical chain project management. Event chain methodology tries to mitigate the effect of motivational and cognitive biases in estimating and scheduling. It improves accuracy of risk assessment and helps to generate more realistic risk adjusted project schedules. History Event chain methodology is an extension of traditional Monte Carlo simulation of project schedules where uncertainties in task duration and costs are defined by statistical distribution. For example, task duration can be defined by three point estimates: low, base, and high. The results of analysis is a risk adjusted proje ...

Project Manager
A project manager is a professional in the field of project management. Project managers have the responsibility of the planning, procurement and execution of a project, in any undertaking that has a defined scope, defined start and a defined finish; regardless of industry. Project managers are first point of contact for any issues or discrepancies arising from within the heads of various departments in an organization before the problem escalates to higher authorities, as project representative. Project management is the responsibility of a project manager. This individual seldom participates directly in the activities that produce the result, but rather strives to maintain the progress, mutual interaction and tasks of various parties in such a way that reduces the risk of overall failure, maximizes benefits, and minimizes costs. Overview A project manager is the person responsible for accomplishing the project objectives. Key project management responsibilities include * ...

Earned Value Management
Earned value management (EVM), earned value project management, or earned value performance management (EVPM) is a project management technique for measuring project performance and progress in an objective manner. Overview Earned value management is a project management technique for measuring project performance and progress. It has the ability to combine measurements of the project management triangle: scope, time, and costs. In a single integrated system, earned value management is able to provide accurate forecasts of project performance problems, which is an important contribution for project management. Early EVM research showed that the areas of planning and control are significantly impacted by its use; and similarly, using the methodology improves both scope definition as well as the analysis of overall project performance. More recent research studies have shown that the principles of EVM are positive predictors of project success. Popularity of EVM has grown in re ...

Human Multitasking
Human multitasking is the concept that one can split their attention on more than one task or activity at the same time, such as speaking on the phone while driving a car. Multitasking can result in time wasted due to human context switching and becoming prone to errors due to insufficient attention. If one becomes proficient at two tasks, it is possible to rapidly shift attention between the tasks and perform the tasks well. Etymology The first published use of the word "multitask" appeared in an IBM paper describing the capabilities of the IBM System/360 in 1965. The term has since been applied to human tasks. Research Since the 1960s, psychologists have conducted experiments on the nature and limits of human multitasking. The simplest experimental design used to investigate human multitasking is the so-called psychological refractory period effect. Here, people are asked to make separate responses to each of two stimuli presented close together in time. An extremely genera ...

Schedule (project Management)
In project management, a schedule is a listing of a project's milestones, activities, and deliverables. Usually dependencies and resources are defined for each task, then start and finish dates are estimated from the resource allocation, budget, task duration, and scheduled events. A schedule is commonly used in the project planning and project portfolio management parts of project management. Elements on a schedule may be closely related to the work breakdown structure (WBS) terminal elements, the Statement of work, or a Contract Data Requirements List. Overview In many industries, such as engineering and construction, the development and maintenance of the project schedule is the responsibility of a full-time scheduler or team of schedulers, depending on the size and the scope of the project. The techniques of scheduling are well developed but inconsistently applied throughout industry. Standardization and promotion of scheduling best practices are being pursued by the ...
