Project Management Terms
A - Project Management Terms
Accept - A decision to take no action against a threat. Project teams typically accept risks when they fall below risk thresholds or when the team thinks it best to act only if and when a threat occurs. (See also risk acceptance)
Acceptance criteria - The specific requirements expected of project deliverables. To be formally accepted, deliverables must meet all acceptance criteria.
Acceptance test - A test in which a team of end users runs a product through its full range of use to identify potential problems.
Acquisition process - This process obtains the personnel and resources necessary for project work. Acquisitions are closely coordinated with project budgets and schedules.
Action item - An activity or task that must be completed.
Action item status - This tracks an action item’s progress from creation to closure. Since work packages comprise multiple action items, keeping action item statuses updated is important for project progress.
Activity - The smallest unit of work necessary to complete a project work package (which includes multiple activities). Time, resources, and finances are required to complete each activity.
Activity code - An alphanumeric value by which activities can be grouped and filtered. A code is assigned to each activity.
Activity identifier - A unique alphanumeric value by which an individual activity can be distinguished. An activity identifier is assigned to each activity.
Activity label - A short descriptor for an activity. Activity labels may be placed below arrows representing activities in activity-on-arrow (AOA) diagrams.
Activity list - This documents all the activities necessary to complete a project. Each activity is accompanied by its activity identifier and a description of the work it entails.
Activity-On-Arrow (AOA) - In this network diagram, arrows represent activities and nodes represent events or milestones. AOA diagrams can only indicate finish-to-start relationships.
Activity-On-Node (AON) - In a network diagram of this nature, nodes represent activities and arrows illustrate logical relationships between activities. AON diagrams can illustrate four relationship types: start-to-start, start-to-finish, finish-to-start, and finish-to-finish.
Actual cost of work performed (ACWP) - This represents the total cost incurred for work done in a given period of time.

Actual effort - The amount of labor performed to complete an activity. It is expressed in person-hours or similar units of work.
Actual expenditure - The sum of costs paid from a budget.
Actual progress - This measures the amount of work completed on a project. It is used to assess the comparison between project progress and project baselines and is usually stated as a percentage.
Adaptive project framework (APF) - An approach to project management that rejects traditional, linear project management and instead accepts changing requirements and allows projects to be affected by external business environments. The ADF stresses flexibility in many aspects of project management and focuses on performing and evaluating project work in stages to allow room for replanning due to changing business goals, objectives, and requirements.
Administrative closure - This refers to the set of formal requirements fulfilled to end a project. Among other things, it involves documenting the formal acceptance of deliverables and ensuring that all relevant information is sent to a project’s sponsor and stakeholders.
Aggregate planning - This strategy uses demand forecasts to manage scheduling and planning for project activities between three and 18 months in advance, so that the necessary resources and personnel can be efficiently acquired or assigned.
Agile - The Agile family of methodologies is a superset of iterative development approaches aimed at meeting ever-changing customer requirements. Agile development proceeds as a series of iterations, or sprints, with incremental improvements made in each sprint. Since agile projects do not have fixed scopes, agile methodologies are adaptive, and the iterative work is guided by user stories and customer involvement.
Agile project management - Agile project management draws from concepts of agile software development. Agile approaches focus on teamwork, collaboration, and stakeholder involvement, as well as the use of iterative development methods.
Agile software development - Agile software development originates from the Agile Manifesto, a set of principles that emphasizes meeting changing requirements through collaborative development and making ongoing improvements through iteration. It stresses the importance of being reactive to rapid changes in external environments.

Apportioned effort - Project work associated with components of a work breakdown structure and performed in proportion, with discrete effort. Since the amount of apportioned effort (which includes activities such as quality assurance) depends directly on the amount of discrete effort, it cannot be considered separately from discrete effort. It is one of three types of activities used to measure work performance as part of earned value management.
Approach analysis - During the project planning phase, this type of analysis is used to examine the various methods by which a project’s goals may be achieved.
Arrow diagramming method (ADM) - A method of constructing a network diagram that uses arrows to represent activities and nodes to represent events or milestones. The ADM is used to construct activity-on-arrow (AOA) diagrams.

Assignment contouring - The process of assigning people to project work for changing numbers of hours per day as the project moves through different stages. Assignment contouring is typically done using project management software.
Assumption - Factors deemed to be true during the project planning process, though proof of their validity is not available. A project’s assumptions can affect its risks and outcomes, so you must consider them carefully.
Authorization - In general, authorization is the power to make decisions that the management grants. The specific remit for authorization varies on a case-by-case basis.
Authorized work - Work that management or others in authority approve.
Avoid - A response to a negative risk that seeks to ensure the risk does not occur or (if the risk cannot be eliminated) seeks to protect the project objectives from the negative risk’s impact. (See also risk avoidance)

Configuration - Configuration of a product involves shaping its functions and characteristics to make it suitable for customer use.
Configuration management - Configuration management ensures that the product of a project meets all necessary specifications and stipulations. It provides well-defined standards for the management and team to guarantee that they meet quality and functional requirements, as well as any other characteristics considered important.
Consensus - A decision agreed upon by all members of a group.
Constraint - A limitation on a project. Among other things, constraints may be financial or based on time or resource availability.

Cost reimbursable contract - A cost reimbursable contract is a contract under which a seller is reimbursed for costs incurred and paid an additional sum as per a predetermined agreement as profit. They are typically negotiated for projects with costs that are not fully known or not well defined.
Cost variance - The Cost variance of a project is its earned value minus its actual cost. A negative cost variance indicates that a project is running over budget. A positive cost variance indicates that a project is running below budget.
Cost/schedule impact analysis - A cost/schedule impact analysis determines the effects of a particular change on a project’s cost or schedule.
Crashing - A schedule compression technique used to speed up project work by increasing the rate at which critical path activities are completed by adding more resources — usually more personnel or more equipment. Crashing increases project costs, so it is used first on activities that can be sped up at the least additional cost.
Critical chain project management (CCPM) - Critical chain project management is an approach to managing projects that emphasizes the resources needed to complete project activities over activity order and durations set in a schedule. It uses resource optimization techniques like resource leveling and requires that activity start times be flexible.

Do nothing option - An element of a project business case that states the consequences, if any, of not undertaking the project.
Drawdown - A method used to exercise control on the release of project funds. Instead of making entire project budgets available from the outset, management may choose to release funds at specific times. These releases are called drawdowns. Drawdowns may coincide with phase gates so that funds are released at the beginning of each phase.
Dummy activity - In activity-on-arrow diagrams, where arrows represent activities, dummy activities show logical relationships between activities. They are not actual activities themselves - dummy activity arrows are drawn with broken lines to differentiate them from regular activity arrows.
Duration - The amount of time taken to complete an activity or task from start to finish.
Duration compression - Duration compression techniques shorten a project’s duration without reducing its scope. This typically requires additional expenditure. There are two main duration compression techniques: crashing and fast tracking. (See also schedule compression technique)
Dynamic systems development method - The dynamic systems development method is one of the agile product development methodologies. Like other members of the agile family, it conducts development in a series of iterations, with user-story-based improvements made in increments.

E - Project Management Terms
Early finish date - The earliest time by which a scheduled project activity can logically finish.
Early start date - The earliest time by which a scheduled project activity can logically start.
Earned schedule - A method of measuring schedule performance that improves upon traditional earned value management. Earned value management tracks schedule variance only in terms of money and not in terms of time and thus does not accurately indicate schedule performance by the end of a project. To address this discrepancy, earned schedule theory uses the same data as traditional earned value management but tracks schedule performances separately with respect to money and time.
Earned value - A concept used to gauge project schedule and cost performance. Portions of the project budget are assigned to components of the work breakdown structure, and successful completion of a work breakdown structure component is understood as value earned through work.
Earned value management - A method of measuring project performance and progress with regard to scope, time, and costs. It is based on the use of planned value (where portions of the budget are allotted to all project tasks), and earned value (where progress is measured in terms of the planned value that is earned upon completion of tasks).

Upgrade projects create a new version of the software, called a release.
Enterprise environmental factors - Internal and external factors that can impact projects. They include such things as climate, available resources, and organizational structure.
Enterprise modeling - Enterprise modeling is the creation of a model to represent an organization’s structure, processes, and resources. Enterprise models are built to increase understanding of how organizations work. They form the basis of improvement or restructuring efforts.

Expert judgment - The practice of using expert opinion to guide decision making.
External dependency - An outside relationship that affects the completion of a project activity.
Extreme programming (XP) - An agile software development methodology that emphasizes a high degree of responsiveness to evolving customer demands. Development cycles in extreme programming are short, and releases are frequent. Its main features include high-volume communication with customers and pair programming.
Extreme project management (XPM) - An approach to project management used mostly for complex projects with a high degree of uncertainty. XPM is designed for projects where requirements are expected to change. Therefore, it focuses on flexibility more than rigid scheduling. Where traditional project management proceeds sequentially through the project management life cycle and thus clearly defines problems, scopes, and solutions, extreme project management accepts that all three aspects will change as the project proceeds and thus emphasizes continual learning over deterministic planning.

Issue log - Project issues and the persons responsible for resolving them. It may also include issue status, plans for resolution, and resolution deadlines.
Iteration - A concept from iterative software development that specifies a fixed time cycle for development work, typically a few weeks long. The development life cycle consists of a number of iterations, sometimes with a functional version of the software produced at the end of each one. Iterative development prioritizes time over scope, so there are rarely concrete requirements to be achieved in an iteration.
Iterative development - Iterative development focuses on developing products in a series of repeated fixed-time iterations, instead of working towards a single deliverable. At the end of an iteration, the team assesses progress and sets targets for the next iteration.

Run book - A comprehensive catalog of information needed to conduct operations and to respond to any emergency situations that arise during operations. It typically details, step by step, all regular operational procedures and emergency responses.
S - Project Management Terms
S-Curve analysis - An s-curve tracks cumulative financial or labor costs. S-Curve analysis is used to compare a project’s cumulative costs at any given point with a cumulative cost baseline created during the planning phase. It allows project managers and sponsors to assess performance and progress.
Schedule - A comprehensive list of project activities and milestones in logical order, with start and finish dates for each component.
Schedule baseline - A schedule baseline is the original project schedule — approved by the project team, sponsor, and stakeholders — by which performance is assessed. Schedule baselines are generally inflexible, though alteration of a schedule baseline via a formal change control process may be allowed.
Schedule compression technique - A schedule compression technique speeds up projects without affecting scope by decreasing the duration of a project’s critical path. There are two main schedule compression techniques: crashing and fast tracking. (See also duration compression)
Schedule model - A logically arranged, time-based plan for project activities. It is used to create a project schedule.
Schedule model analysis - Schedule model analysis examines the project schedule created from a schedule model. It aims to optimize the schedule, usually via the use of scheduling software.
Schedule network analysis - Schedule network analysis uses a variety of techniques to identify early and late start and finish dates for project activities and thus to create project schedules.
Schedule performance index (SPI) - The ratio of earned value to planned value at a given point in time. It shows whether a project is running to schedule. An SPI lower than one indicates the project is behind schedule. An SPI higher than one indicates the project is ahead of schedule.
Schedule variance - Schedule variance is the difference between earned value and planned value at a given point in time.
Scientific management - Scientific management was an early attempt to bring scientific approaches to process management. Its earliest form was derived from a 1911 monograph by Frederick W. Taylor, who focused on increasing economic efficiency via the analysis and optimization of labor processes.
Scope - The scope of a project constitutes everything it is supposed to accomplish in order to be deemed successful.
Scope baseline - The set of requirements, expectations, and work packages approved as project deliverables. It is used to guide and assess project performance.
Scope change management - Scope change management deals with amendments to the scope as set in the scope baseline and project management plan. Since scope amendments typically affect cost and schedule estimates, scope change management involves revising estimates and adequately communicating these to stakeholders, as well as obtaining the resources necessary to fulfill new scope requirements.
Scope creep - Scope creep refers to gradual changes in project scope that occur without a formal scope change procedure. Scope creep is considered negative since unapproved changes in scope affect cost and schedule but do not allow complementary revisions to cost and schedule estimates.
Scrum - Scrum is an iterative development procedure used in software development projects. Scrum-based projects focus on prioritizing requirements and working towards a clear set of goals over a set time period, called a sprint. The development team thus works through the list of requirements over a number of sprints. Scrum-based projects usually do not have project manager. Instead, the project team meets daily for progress updates.
Secondary risk - A risk created by a risk response.
Security - Security in project management refers broadly to protecting humans, information, and resources from risk.
Six Sigma - An approach to process management that focuses on the near total elimination of product or service defects. It uses quality management methods to improve and optimize processes involved in the production of a product or service so that 99.99966 percent of process outcomes are defect-free.
Slack time - The length of time an activity's early start can be delayed without affecting project duration. (See also float)
Slip chart - A slip chart graphically compares predicted activity completion dates with originally planned completion dates.
Slippage - The negative variance between planned and actual activity completion dates. Slippage may also refer to the general tendency of a project to be delayed beyond planned completion dates.
Soft project - A soft project does not have a physical output.
Software engineering - Software engineering is generally defined as the use of engineering principles in software development. It systematically employs scientific and technological approaches in the design, operation, and modification of software.
Spiral life cycle - An IT system’s development model that aims to learn from experience by drawing from both iterative development and the waterfall model. It has four sequential phases: identification, design, construction, and evaluation and risk analysis. At the end of each life cycle, an iteration is assessed by the customer, and the spiral sequence begins again upon receipt of customer feedback. The spiral model is typically used in long-term projects or those where requirements are expected to vary, and customer feedback is to be incorporated in phases.
Sponsor - A sponsor has ultimate authority over a project. They provide high-level direction, approve project funding as well as deviations from cost and budget, and determine project scope. Sponsors are typically members of the senior management and are expected to provide high-level support for a project.
Sprint - In iterative project development, a sprint is a fixed unit of time during which the project typically passes through a complete development life cycle. A sprint is usually a few weeks long.
Stakeholder - In project management, a Stakeholder is any party with an interest in the successful completion of a project. More generally, the term refers to anyone who is affected by a project. (See also project stakeholder)
Standards - A standard prescribes a collection of standardized rules, guidelines, and characteristics requirements for processes or products that are approved by a recognized body. Standards are not by definition mandatory. They are adopted by consensus, although they may be enforced as a requirement for participation in certain markets.
Start-To-Finish - In a start-to-finish relationship, a successor activity cannot finish until a predecessor activity has started.
Start-To-Start - In a start-to-start relationship, a successor activity cannot start until a predecessor activity has started.
Statement of work (SoW) - A Statement of work is a comprehensive and detailed list of deliverables expected under a contract, with expected dates for each deliverable.
Steering committee - A steering committee provides high-level strategic guidance on a project. It typically comprises individuals from a number of stakeholder organizations and serves to provide consensus-based direction on projects with a large number or a diversity of stakeholders.
Story point - In sprint-based projects, a story point is a measure of the amount of work required to implement a particular user story. Assigning and totaling story points allows project teams to target a realistic number of user stories for action during an iteration or sprint.
Successor activity - In a schedule, a successor activity logically comes after and depends on an activity immediately preceding it.
Summary activity - In a network diagram, a summary activity combines a set of related activities and visually represents them as a single activity.
Sunk cost - A cost that cannot be recovered once spent.
Systems development life cycle (SDLC) - In systems engineering, the systems development life cycle is the process of creating, releasing, and maintaining an information system, which may comprise hardware, software, or both. The typical SDLC has six sequential phases: planning, analysis, design, implementation, testing, and maintenance.
Systems engineering - A field of engineering that applies principles of systems thinking to the development of complex systems. Since complex systems are more difficult to coordinate and make cohesive, systems engineering focuses on developing and optimizing systems as interactive wholes instead of sums of parts. As complex systems comprise both technical and human elements, systems engineering is, by nature, interdisciplinary.
T - Project Management Terms
Task - In project management, a task is a unit of work or activity needed for progress towards project goals. Typically, a task must be completed by a set deadline. Tasks may be further broken down into assignments or subtasks.
Task analysis - A task analysis details the actions or resources required to complete a task.
Testing - The testing phase involves assessment of the product developed so as to gauge quality and performance and to determine whether requirements have been met.
Theory of constraints - The theory of constraints explains that any process is limited from optimum performance by its weakest link or links, called constraints. The theory of constraints methodology involves identifying these weak links via a strategy called focusing and improving them until they no longer limit performance.
Threat - A negative risk that could adversely affect project objectives.
Three-point estimating - A superset of estimating techniques that use averages (or weighted averages) of most likely, optimistic, and pessimistic costs, and duration estimates to form final estimates.
Time and material contract - A time and material contract pays per unit of time and reimburses materials costs for contracted work.
Time chainage diagram - In project management, a time chainage diagram graphically represents scheduled activities for a hard project completed sequentially over a geographic distance, such as the construction of a motorway or the laying of a pipeline. It thus provides both a scheduled time and a relative geographic location for each activity.
Time limit - The time limit for a task is the window of time or deadline by which it must be completed.
Time-scaled network diagram - A network diagram is time scaled if the lengths of activities are drawn to scale to indicate their expected durations.
Timebox - Timeboxing is a project management strategy that prioritizes meeting deadlines over scope requirements. It involves assigning specific lengths of time, called timeboxes, to project activities. Project teams work to address as many requirements as possible within each timebox, proceeding to successor activities once the time limit has passed.
Timeline - A Timeline is a graphical, sequential representation of project activities.
To-Complete Performance Index (TCPI) - A project’s to-complete performance index is the cost performance it needs to achieve to be completed within budget. The TCPI is calculated as the ratio of work remaining to budget remaining.
Tolerance - The acceptable level of variance in project performance. The project sponsor is typically informed if tolerance levels are crossed.
Top-Down estimating - Top-Down estimating uses historical data from similar projects to compute time and cost estimates. (See also analogous estimating)
Total cost of ownership (TCO) - The total cost of ownership estimates the sum total of direct and indirect costs incurred in the purchase, operation, and maintenance of an asset through its life.
Total float - The length of time an activity can be delayed from its early start date without affecting the project end date.
Trigger condition - A condition that causes a risk to occur. Trigger conditions can serve as warning signs that risks have occurred or are about to occur. (See also risk trigger)
U, V, W, and X - Project Management Terms
Unified process - A unified process may refer to any one of a family of iterative software development process frameworks. Unified processes have four phases: inception, elaboration, construction, and transition. Each phase comprises a number of timeboxed iterations, which in turn involve a cycle of specifying requirements, analysis, design, implementation, and testing, with emphases on these shifting as the project team proceeds through iterations. Each iteration results in an improved version of the system called an increment.
Use case - In software development, a use case is a step-by-step list of actions that end users would take to achieve specific goals. Use cases facilitate end user-focused software testing.
User story - A project requirement stated in one sentence. It typically identifies users, real or hypothetical, what these users want from software, and why they want it. Project development teams prioritize user stories in each iteration by assigning story points
V life cycle - The V in V life cycle stands for verification and validation. It is a sequential software development process that matches a corresponding testing phase to each phase in the software development life cycle. During the verification phase, a project team works at increasingly granular levels of detail to identify requirements and design, and then builds the software. Validation proceeds in the opposite direction, as testers examine software components in turn before moving on to systems testing and finally checking that the project as a whole meets requirements.
Value engineering - Value engineering seeks to increase the functionality-to-cost ratio of a product by providing improved functionality at lower cost. Some applications of value engineering attract criticism, as manufacturers may decrease costs by using lower-quality components that decrease product lifespans.
Value for money ratio - In project management, the value for money ratio is expressed as the ratio of financial and other benefits to the resources expended in a project.
Value tree - A hierarchical model of the characteristics of a product or service that determine its value.
Variance analysis - The practice of investigating deviations between planned and actual performance.
Variance at completion (VAC) - A project’s variance at completion is the difference between its budget at completion and its estimate at completion.
Vertical slice - A performance indicator that demonstrates progress across all project components or performance areas at a given point in time.
Virtual design and construction (VDC) - A method based on using technology in design and construction projects. It uses building information modeling (BIM) tools that focus on designable and manageable aspects of projects to create integrated models that predict project performance.
Virtual team - A virtual team comprises people from different organizations, locations, or hierarchies. It is not necessarily the same as a remote team, which is a group of people working together from different locations.
Waterfall model - The Waterfall model is a software development life cycle in which development phases are sequential, non-iterative, and do not overlap. It is typically reserved for small projects with straightforward, clearly defined requirements since a sequential development process makes it difficult to revisit the analysis and design phases once testing has begun. (See also linear sequential model)
Weighted milestone method - The weighted milestone method allows project managers to estimate earned value by splitting work packages into weighted segments. Each segment represents a portion of the budget value for the work package and ends with a milestone. When a segment milestone is classified as complete, a portion of the total work package value has been earned.
What-If scenario analysis - A simulation technique that allows project managers to determine and compare specific conditions’ effects on project schedules and objectives.
Wideband delphi - An estimation technique based on expert consensus. Each member of an estimation team uses a work breakdown structure to create anonymous estimates of the effort required to complete each project element or work package. The estimates are then reviewed as a group before the experts create new estimates, and the process is repeated for a number of rounds until a consensus is reached. (See also delphi technique)
Work - In project management, work is the amount of effort needed to complete a task.
Work authorization system - A formal procedure to ensure that project work is performed on time and in logical order.
Work breakdown structure (WBS) - A Work breakdown structure is a comprehensive, hierarchical model of the deliverables constituting the scope of a project. It details everything a project team is supposed to deliver and achieve. A work breakdown structure categorizes all project elements, or work packages, into a set of groups and may be used to form cost estimates.
Work breakdown structure dictionary - A document that details, describes, and provides scheduling information for every element of a work breakdown structure. It may be thought of as a dictionary-cum-schedule of work packages.
Work package - The work packages of a project are its lowest-level deliverables. They are detailed in a work breakdown structure dictionary.
Work stream - In project management, a work stream is a logically arranged series of activities that must be completed to pursue project objectives. The term typically refers to the full sequence of work activities from project initiation to project closure.
Workaround - A way to circumvent a problem which does not have a permanent solution or for which no adequate response was planned.
X-Bar control charts - An x-bar control chart includes two separate charts that display the means and sample ranges for a number of periodically gathered, same-size samples. The sampled data constitute some characteristic of a product or a process.
