Project management is the practice of initiating, planning, executing, controlling, work plan for project closing the work of a team to achieve specific goals and meet specific success criteria at the specified time. The primary challenge of project management is to achieve all of the project goals within the given constraints. This information is usually described in project documentation, created at the beginning of the development process.
As a discipline, project management developed from several fields of application including civil construction, engineering, and heavy defense activity. The 1950s marked the beginning of the modern project management era where core engineering fields come together to work as one. Project management became recognized as a distinct discipline arising from the management discipline with engineering model. PERT and CPM are very similar in their approach but still present some differences.
Because of this core difference, CPM and PERT are used in different contexts. At the same time, as project-scheduling models were being developed, technology for project cost estimating, cost management and engineering economics was evolving, with pioneering work by Hans Lang and others. There are a number of approaches to organizing and completing project activities, including: phased, lean, iterative, and incremental. Plan: The planning and forecasting activities. Process, the overall approach to all activities and project governance.
People, and the dynamics of how they collaborate and communicate. Power, Projects are which describes all lines of authority, decision-makers, organograms, policies for implementation and the likes. 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. Many industries use variations of these project stages and it is not uncommon for the stages to be renamed in order to better suit the organization. While the phased approach works well for small, well-defined projects, it often results in challenge or failure on larger projects, or those that are more complex or have more ambiguities, issues and risk. Lean project management uses the principles from lean manufacturing to focus on delivering value with less waste and reduced time. In critical studies of project management it has been noted that phased approaches are not well suited for projects which are large-scale and multi-company, with undefined, ambiguous, or fast-changing requirements, or those with high degrees of risk, dependency, and fast-changing technologies.
These complexities are better handled with a more exploratory or iterative and incremental approach. Applying the first three of the five focusing steps of TOC, the system constraint for all projects, as well as the resources, are identified. To exploit the constraint, tasks on the critical chain are given priority over all other activities. As such, it defines a successful project as output-oriented rather than activity- or task-oriented. Project production management is the application of operations management to the delivery of capital projects. In addition, BRM practices aim to ensure the 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.
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. Under BRM the agreement might be to achieve a specified reduction in staff hours required to process and maintain staff data. Earned Schedule is an extension to the theory and practice of EVM. Regardless of the methodology or terminology used, the same basic project management processes or stages of development will be used.
The initiating processes determine the nature and scope of the project. If this stage is not performed well, it is unlikely that the project will be successful in meeting the business’ needs. The key project controls needed here are an understanding of the business environment and making sure that all necessary controls are incorporated into the project. The initiating stage should include a plan that encompasses the following areas. These areas can be recorded in a series of documents called Project Initiation documents. Project Initiation documents are a series of planned documents used to create order for the duration of the project. The main purpose is to plan time, cost and resources adequately to estimate the work needed and to effectively manage risk during project execution.
