Here is our dictionary of project management terms and acronyms. Understanding these terms and acronyms is an essential step towards success in project management.

The ideas from Agile software development applied to project management. Agile methods promote a process that encourages development iterations, teamwork, stakeholder involvement, objective metrics and effective controls.

Any factors that you are assuming to be in place that will contribute to the successful outcome of the project.

A performance management tool which began as a concept for measuring whether the smaller-scale operational activities of a company are aligned with its larger-scale objectives in terms of vision and strategy.

A baseline is an approved configuration item, for example a project plan that has been signed off for execution. The baseline records the planned costs, schedule and technical requirements against which a project is measured.

A strategic planning tool used to provide the terms-of-reference for new projects. The BOSCARD acronym stands for background, objectives, scope, constraints, assumptions, risks and deliverables. These headings are commonly found in terms-of-reference and project initiation documents.

A document recording the justification for starting a project. It describes the benefits, costs and impact, plus a calculation of the financial case.

Capital Expenditure (CAPEX) is the amount a company spends to buy fixed assets, or to add to the value of an existing fixed asset with a useful life that extends beyond the taxable year.

The factors that you will need to consider during the life of the project that you cannot change. These may include deadlines, regulatory requirements and dependencies on other projects to deliver.

The cost benefit analysis is used to show the expected benefits of a project are sufficient to warrant the cost of carrying it out. Monetary units are usually used for the comparison.

A method of planning and managing projects that puts more emphasis on the resources needed to carry out project tasks. It is the Theory of Constraints (ToC) applied to projects.

The critical path is the sequence of activities that must be completed on time for the entire project to be completed on schedule. It is the longest duration path through the work plan. If an activity on the critical path is delayed by one day, the entire project will be delayed by one day unless another activity on the critical path can be finished a day earlier than planned.

A technique used to predict project duration by analysing which sequence of activities has the least amount of scheduling flexibility.

A factor identified as essential to achieving a successful project.

A tangible or intangible object produced through project execution. A deliverable can be created from multiple smaller deliverables.

A method used to estimate the likelihood and outcome of future events. A group of experts exchange views, and each individually gives estimates and assumptions to a facilitator who reviews the data and issues a report. This process continues until consensus is reached.

Any events or work that are either dependent on the outcome of the project or the project will depend on.

An approach where you monitor the project plan, actual work and work completed value to see if a project is on track. Earned Value shows how much of the budget and time should have been spent for work done.

Estimating uses a number of tools and techniques to produce an approximation of a projects timescale and cost. The estimate has a single total value and may have identifiable component values.

The time a task can be delayed without delaying the project. Tasks on the critical path have no float.

A popular project management bar chart that tracks tasks across time. When first developed in 1917, the Gantt chart did not show the relationships between tasks. This has become common in current use, as both time and interdependencies between tasks are tracked.

The addition of unnecessary features or refinements, beyond the agreed scope, into a product or service in an attempt to improve customer satisfaction.

Net Present Value (NPV) is an estimate that helps organisations determine the financial benefits of long-term projects. NPV compares the value of a pound today to the value of that same pound in the future, taking inflation and returns into account.

P3M3, also known as the Portfolio, Programme and Project Management Maturity Model is a reference guide for structured best practice. It breaks down the broad disciplines of portfolio, programme and project management into a hierarchy of Key Process Areas (KPAs).

Named after Italian economist Vilfredo Pareto, the Pareto Principle is the idea that by doing 20% of the work you can produce 80% of the benefit of doing the whole job. Or for quality improvement, most problems are produced by a few key causes.

The law that says, Work expands so as to fill the time available for its completion. Articulated by Cyril Northcote Parkinson as the first sentence of a humorous 1955 essay published in The Economist magazine.

A tool used to schedule, organise and co-ordinate tasks within a project. PERT stands for Program Evaluation Review Technique, a method developed by the United States Navy in the 1950s to manage the Polaris submarine missile programme. Also known as a precedence diagram, a network chart and logic diagram.

A strategic planning tool used to evaluate the impact political, economic, social and technological factors might have on a project. It involves an organisation considering the external environment before starting a project.

Planning poker helps agile teams estimate the time and effort needed to complete each initiative on their product backlog.

Owned by the Project Management Institute (PMI), the Project Management Body of Knowledge (PMBOK) is a collection of processes and knowledge areas accepted as best practice within the project management discipline.

Project Management Professional (PMP) is a globally recognised certification in project management offered by the Project Management Institute (PMI).

PRINCE2 is an approach to project management, released in 1996 as a generic project management method. It provides a method for managing projects within a clearly defined framework. PRINCE2 describes procedures to co-ordinate people and activities in a project, how to design and supervise the project and what to do if the project has to be adjusted if it doesn't develop as planned.

A simple project management tool, often in the form of a spreadsheet, used to track risks, assumptions, issues and dependencies.

Everything needed to complete a project, but in particular, people and money.

There may be potential external events that will have a negative impact on your project if they occur. Risk refers to the combined likelihood the event will occur and the impact on the project if the event does occur. If the combined likelihood of the event happening and impact to the project are both high, you should identify the potential event as a risk and put a plan in place to manage it.

The overall definition of what the project should achieve and a specific description of what the result should be. A major ingredient of scope is the quality of the final product.

When a company decides to work in two-week sprints, it has the opportunity to reflect, make adjustments and plan every fourteen days based on events and conditions.

A stakeholder is anyone, internal or external to an organisation that has an interest in a project or will be affected by its deliverables.

An SOP describes the activities needed to complete tasks within industry regulations, country or international laws, and your own standard business processes. SOPs are often requested as part of an audit. The auditors compare the SOP with the live operating procedures to check operations are in accordance with the documented standards.

The specification of software tests that are conducted from the end user perspective. Use cases focus on operating the software as an end user would during their day-to-day activities.

A sequential development process, in which development flows steadily downwards (like a waterfall) through the phases of initiation, analysis, design, build, test and maintenance. To follow the waterfall model, you move from one phase to the next sequentially, with no overlapping or iterative steps.

A hierarchical decomposition of the deliverables needed to complete a project. It breaks the deliverables down into manageable work packages that can be scheduled, costed and have resources assigned to them.
