Project management

Source: Wikipedia, the free encyclopedia.

Project management is the process of leading the work of a team to achieve all project goals within the given constraints.[1] This information is usually described in project documentation, created at the beginning of the development process. The primary constraints are scope, time, and budget.[2] 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 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-making.

A project is a temporary and unique endeavor designed to produce a product, service, or result with a defined beginning and end (usually time-constrained, and often constrained by funding or staffing) undertaken to meet unique goals and objectives, typically to bring about beneficial change or added value.[3][4] The temporary nature of projects stands in contrast with business as usual (or operations),[5] which are repetitive, permanent, or semi-permanent functional activities to produce products or services. In practice, the management of such distinct production approaches requires the development of distinct technical skills and management strategies.[6]

master builders themselves, for example, Vitruvius (first century BC), Christopher Wren (1632–1723), Thomas Telford (1757–1834), and Isambard Kingdom Brunel (1806–1859).[7] In the 1950s, organizations started to apply project-management tools and techniques more systematically to complex engineering projects.[8]

Henry Gantt (1861–1919), the father of planning and control techniques

As a discipline, project management developed from several fields of application including civil construction, engineering, and heavy

defense activity.[9] Two forefathers of project management are Henry Gantt, called the father of planning and control techniques,[10] who is famous for his use of the Gantt chart as a project management tool (alternatively Harmonogram first proposed by Karol Adamiecki);[11] and Henri Fayol for his creation of the five management functions that form the foundation of the body of knowledge associated with project and program management.[12] Both Gantt and Fayol were students of Frederick Winslow Taylor's theories of scientific management. His work is the forerunner to modern project management tools including work breakdown structure (WBS) and resource allocation

Project management types

Project management methods can be applied to any project. It is often tailored to a specific type of project based on project size, nature, industry or sector. For example, the construction industry, which focuses on the delivery of things like buildings, roads, and bridges, has developed its own specialized form of project management that it refers to as construction project management and in which project managers can become trained and certified.[17] The information technology industry has also evolved to develop its own form of project management that is referred to as IT project management and which specializes in the delivery of technical assets and services that are required to pass through various lifecycle phases such as planning, design, development, testing, and deployment. Biotechnology project management focuses on the intricacies of biotechnology research and development.[18] Localization project management includes application of many standard project management practices to translation works even though many consider this type of management to be a very different discipline. For example, project managers have a key role in improving the translation even when they do not speak the language of the translation, because they know the study objectives well to make informed decisions.[19] Similarly, research study management can also apply a project manage approach.[20] There is public project management that covers all public works by the government, which can be carried out by the government agencies or contracted out to contractors. Another classification of project management is based on the hard (physical) or soft (non-physical) type.

Common among all the project management types is that they focus on three important goals: time, quality, and cost. Successful projects are completed on schedule, within budget, and according to previously agreed quality standards i.e. meeting the Iron Triangle or Triple Constraint in order for projects to be considered a success or failure.[21]

For each type of project management, project managers develop and utilize repeatable templates that are specific to the industry they're dealing with. This allows project plans to become very thorough and highly repeatable, with the specific intent to increase quality, lower delivery costs, and lower time to deliver project results.

Approaches of project management

A 2017 study suggested that the success of any project depends on how well four key aspects are aligned with the contextual dynamics affecting the project, these are referred to as the four P's:[22]

  • Plan: The planning and forecasting activities.
  • Process: The overall approach to all activities and project governance.
  • People: Including dynamics of how they collaborate and communicate.
  • Power: Lines of authority, decision-makers, organograms, policies for implementation and the like.

There are a number of approaches to organizing and completing project activities, including phased, lean, iterative, and incremental. There are also several extensions to project planning, for example, based on outcomes (product-based) or activities (process-based).

Regardless of the methodology employed, careful consideration must be given to the overall project objectives, timeline, and cost, as well as the roles and responsibilities of all participants and stakeholders.[23]

Benefits realization management

Benefits realization management (BRM) enhances normal project management techniques through a focus on outcomes (benefits) of a project rather than products or outputs and then measuring the degree to which that is happening to keep a project on track. This can help to reduce the risk of a completed project being a failure by delivering agreed upon requirements (outputs) i.e. project success but failing to deliver the benefits (outcomes) of those requirements i.e. product success. Note that good requirements management will ensure these benefits are captured as requirements of the project and their achievement monitored throughout the project.

In addition, BRM practices aim to ensure the strategic alignment between project outcomes and business strategies. The effectiveness of these practices is supported by recent research evidencing BRM practices influencing project success from a strategic perspective across different countries and industries. These wider effects are called the strategic impact.[24]

An example of delivering a project to requirements might be agreeing to deliver a computer system that will process staff data and manage payroll, holiday, and staff personnel records in shorter times with reduced errors. Under BRM, the agreement might be to achieve a specified reduction in staff hours and errors required to process and maintain staff data after the system installation when compared without the system.

Critical path method

Critical path method (CPM) is an algorithm for determining the schedule for project activities. It is the traditional process used for predictive-based project planning. The CPM method evaluates the sequence of activities, the work effort required, the inter-dependencies, and the resulting float time per line sequence to determine the required project duration. Thus, by definition, the critical path is the pathway of tasks on the network diagram that has no extra time available (or very little extra time)."[25]

Critical chain project management

Critical chain project management (CCPM) is an application of the theory of constraints (TOC) to planning and managing projects and is designed to deal with the uncertainties inherent in managing projects, while taking into consideration the limited availability of resources (physical, human skills, as well as management & support capacity) needed to execute projects.

The goal is to increase the flow of projects in an organization (

Earned value management

Earned value management (EVM) extends project management with techniques to improve project monitoring.
