100+ Project Management Terms in Alphabetical Order

Here’s our complete list of over 100 project management terms organized in alphabetical order.


A – Project Management Terms

Acceptance criteria
The metric by which a project will be measured to determine whether it’s successful or not. These are predefined requirements that must be met by the project in order for it to be considered done, whether that’s a task, user story or the whole project.

A methodology for project and product management, typically used to deliver software projects in an iterative way with short bursts of work called “sprints”. Though initially designed as a process for IT and engineering projects, it has since been successfully applied to other industries like marketing. As the methodology has gained in popularity, agile (with a small “a”) has become a general business approach to support a more flexible working style with quick turn-around.

Arrow Diagramming Method
A network diagramming technique that represents the start and end of activities with arrows to help with scheduling in the project planning phase. The longer the duration of the project, the longer the length of the arrow.

Devin Deen explains how to use Activity on the Arrow diagramming to chart the critical path in this video.


B – Project Management Terms

Backlog is a term from the Agile methodology Scrum, but is also used across industries to track every single thing that is needed to complete a product in development. It is also used to capture requests for modifying the product and ensuring delivery with scope.

A baseline is an estimate of the project’s scope, schedule and costs that is created during the planning stage. Its main purpose is to serve as a reference that is compared to the project performance once the execution phase begins. The baseline is established based on different sources of information such as project files from previous projects or subject matter expert opinions.

Business case
A business case is either a written or verbal proposition used to educate and sway the decision-makers in an organization to take on a project because it is going to deliver a return on investment or provide some worthwhile benefit.

Business plan
A formal document that clearly defines the business goals of a project and how to attain them. It is also called a Business Case. It includes the plans to fulfill these goals. There may also be some background information about the organization or team tasked to reach this goal.


C – Project Management Terms

Capability Maturity Model (CMM)
Developed from a US Department of Defense study, the model is used to develop and refine software processes. It helps to model the maturity of the capability of business process by defining steps and managing result metrics to optimize the process.

Change control
The term for a process to systemically monitor and approve or reject any change requests made to a product or project. The process is designed to increase project efficiency and minimize scope creep by controlling every change and ensuring that changes are made according to set requirements for approving change.

Change management
The method for managing project change requests and application of the change control process as defined above. The goal with change management is to avoid scope creep in a project and produce maximum efficiency during the project.

Change Management Plan
Process to implement and manage change in a project. Will determine if a requested change is worth pursuing or not depending on factors such as cost, time and other impacts to the project. It also is used to respond to changes that occur in the project whether due to the environment, equipment or other factors.

Case study
Used for a variety of purpose, case studies are generally research-based papers that deeply examines use cases of products in given applications or how different industries applied specific practices or approaches to their projects.

Certified Associate in Project Management (CAPM)
An entry-level certification offered by the Project Management Institute.

Communications log
A record of continuous documentation of communications between project stakeholders managed by the project manager. Project managers make logs to manage change requests or to document public sector projects for future audit or oversight committees in more formal project environments. In more informal organizations, communications logs can be chats, discussions and email threads, and in fact some project management software adds email conversations related to the project directly on the task or project level, to keep project documentation organized.

Working with one or more parties on the same project and similar goals. It’s the act of delegating and communicating between team members and distinct teams in order to better serve the product by providing more minds and hands. More than that, though, collaboration is a way of working with new tools like social platforms, real-time document sharing and editing, and remote working. For some companies, collaboration is perceived to be a “culture” promoted within the business to support Agile or iterative ways of running projects or simply to support knowledge sharing within the org.

A plan for possible disaster occurring during your project, whether that be of the man-made or natural variety. It’s not merely data backup, but includes that and every other detail to ensure the project isn’t derailed by considering short- and long-term events and how to respond to them.

Cost Benefit Analysis
How to calculate the potential benefits of a project in terms of money and then subtract the cost of the project from this figure. A cost benefit analysis will then determine if the project is worth the investment and whether it should be initiated or passed on.

Cost overrun
This is the actual cost that exceeds the estimated cost in the budget, also known as a cost increase or budget overrun. It usually is unexpected and unwanted as it requires finding new resources to cover these unseen expenses.

Critical path method (CPM)
An algorithm for scheduling a set of project activities, typically the “critical path” or shortest path through a project. It was developed in the late 1950s within the DuPont organization and Remington Rand company as a method to know mission-critical tasks. Modern project management software applications can streamline finding your project’s critical path to help you manage scope and monitor the project.


D – Project Management Terms

Used to define roles and responsibilities in the project. This acronym stands for driver, the individual who drives decisions, approvers, who make the decision, contributors, who work on the project or provide knowledgeable guidance, and informed, whose work is likely to be affected by the decision.

A graphical way to share essential project data with stakeholders, a dashboard which makes diverse amounts of data and its underlying information easily digestible. Traditionally, dashboards were created “manually” by assembling select pie charts or data graphs in a presentation view. The data however, was often outdated by the time of the presentation. Modern project management tools offer real-time dashboards, so the data is viewed usually by bringing a laptop or tablet to a presentation or through client logins to the software so everyone has access to the freshest data.

Tasks or other activities that are interdependent on a project. Often one activity cannot take place prior to another one being completed. In this way, they are linked in a project and can be noted as such in online project management tools. When you add a dependency in online project management software, you create a dependent-virtual link between two tasks to demonstrate that constraint.

Something contracted for delivery. It is a tangible item or intangible objective, but crucial to the success of the project. It can be a report, a document, some project building block or the end product delivered at the end of a project.


E – Project Management Terms

Earned value management (EVM)
A way to measure project performance, and is commonly used in government projects. Here’s how EVM can be applied over the course of a project’s duration.

In a project context, estimation is the way to make accurate budgets or timelines for a project. There are various techniques in estimating to help you get the most accurate predictions of cost and time.

Read our post on getting your team to help you get the best estimates.

Event chain diagram
This is a visual way of demonstrating the relationship between events and tasks and how they impact one another.

Event chain methodology
A method that focuses on identifying and managing events and series of events that impact a project’s schedule.


F – Project Management Terms

This refers to a technique project managers use to speed up their projects. Typically, schedules are analyzed to identify areas where some tasks can be done in parallel versus sequentially, or where new resources can be added mid-way through a project, adjusting the project plan.

Feasibility study
A feasibility study is a way to ascertain whether the proposed plan or methodology prescribed is practical in terms of fulfilling the goals of a project. For large projects, these can be detailed research studies. For smaller projects, they can be more informal assessments using existing business documentation like market research and informal internal polls with key stakeholders.

This refers to time that a task can be delayed without blocking other tasks, or in layman’s terms: “wiggle room.”


G – Project Management Terms

Henry Gantt
American mechanical engineer and management consultant who developed the Gantt chart in 1910.

Gantt chart
The horizontal bar chart that illustrates a project’s schedule from start to finish by demonstrating the task duration visually. It’s named after Henry Gantt, who developed it in 1910 (though Karol Adamiecki did so, too, independently in 1896). Gantt charts are traditionally used in Waterfall project planning, for long-term projects that have many task dependencies. They are the backbone of formal project management software applications, most of which are now fully online and can be used interactively and collaboratively.

Learn more in our Ultimate Guide to Gantt Charts.


H – Project Management Terms

Hybrid methodology
Refers to the use of two or more separate methodologies on a project, commonly a blend of Agile and Waterfall project management methods, though sometimes incorporating kanban, lean or other methodologies of project management. Employing hybrid methodology enables teams to apply what works best where and when it is most needed, or to suit different teams within an organization.

Learn more about how teams can use hybrid methodology in this piece by contributor Mario Henrique Trentim.


I – Project Management Terms

This refers to the first phase in the lifecycle of a project, according to traditional project management practices.  It’s the stage in the process where the project is first conceived and scoped. It also involves the hiring of a team, setting up a project office and reviewing the project, as well as gaining approval for the project.

Iterative and incremental development
This is a method of project development, usually applied in software and IT projects, that evolved in response to weaknesses in the waterfall model to support rapid deployment. It is commonly employed in Agile and Lean projects, often in response to end-user feedback in product development cycles.


K – Project Management Terms

This term literally means signboard or billboard in Japanese and was developed in Japan by Taiichi Ohno, an industrial engineer at Toyota, as a scheduling system for lean and just-in-time production. Kanban project management controls the logistical chain from a production point of view, formally, but has since been used more popularly as a visual way to track tasks for individuals or teams. This is usually executed with online kanban software.

Learn how Kanban and Scrum differ in the blog Kanban vs. Scrum: Which is Better?

Key Performance Indicators (KPIs)
A quantifiable measurement that is used to evaluate a project and determine if it is performing as planned. KPIs can be anything from cost to time, scope or quality.

Kickoff meeting
This refers to the first meeting to formally start a project and usually involves key stakeholders, team members and clients, depending on the nature of the project. There are best practices defined for how to run this type of meeting, which usually includes communicating the overall project vision, plan, processes and expectations.

Lean startup
This method (or movement) for developing businesses and products was first proposed in 2011 by Eric Ries and is based on his experience working on various startups. It says that startups can shorten their product development cycles by adopting a combination of business-hypothesis-driven experimentation, iterative project releases and validated learning

Lean manufacturing
A theory of expenditure of resources for any means other than the creation of value for the customer is considered wasteful and should be deleted.


M – Project Management Terms

A very large-scale work, often spanning multiple years.

This is a way to mark a specific point along the lifecycle of a project’s timeline to bookmark upcoming major accomplishments, including the start, finish, external review, budget checks, etc. They are points along the project that must be reached according to schedule for the successful completion of the project.

Learn more about how to use milestones in project scheduling.

Minimally Viable Product (MVP)
This is a term that refers to releasing a product with the highest return on investment versus risk, and was coined as a term by Frank Robinson and popularized by Steve Blank and Eric Ries. It often refers to the product or project scope pre-launch to avoid unnecessary scope creep; that is, teams can get stuck trying to build new features into products in an attempt to please stakeholders or end users, rather than releasing the MVP and getting the product released quicker to the market.

This is a phase in the project management lifecycle, specifically the act of continuous awareness of the course of a project plan. Project monitoring involves checking whether a project is proceeding according to schedule and within the proposed budget, as well as checking into the health of your team. Monitoring can be accomplished through reporting, dashboards and active management with a team.

Learn tips on How to Monitor Projects.

MoSCoW method
A technique used to prioritize through the use of a four-step process. MoSCoW is an acronym for must-have, should have, could have and won’t have or not right now. By giving each task one of these distinctions, project managers can determine when or if they should be executed.


N – Project Management Terms

In project planning, slack refers to the amount of extra room for time in the plan to accommodate time delays, should they occur. (It’s also the name of a software product used for collaborative communications among teams.) Often, project managers want to find the slack they have in their schedule to determine whether they need to reallocate resources to accommodate schedule variations.

Watch Devin Deen explain How to Find Slack in Your Project Schedule.

In a project, the sponsor refers to the owner or promoter of a project and often represents a client’s goals. This role is distinct from the project manager.

In a project or an organization, stakeholders are people or groups that have an interest or concern regarding the project. It might be a client in a private organization or the public in a government project or it could be end users on a product.
