Quick Reference

Triple Constraint

The model that describes the three primary competing constraints on any project: scope, time, and cost. Changing one constraint inevitably impacts the others, requiring trade-off decisions. Quality is sometimes added as a fourth dimension at the center.

Work Breakdown Structure (WBS)

A hierarchical decomposition of the total scope of work into manageable sections. Each descending level represents an increasingly detailed definition of the project work, ultimately breaking down to work packages that can be estimated, scheduled, and assigned.

Critical Path Method (CPM)

A scheduling technique that identifies the longest sequence of dependent tasks in a project, determining the minimum project duration. Tasks on the critical path have zero float, meaning any delay directly extends the project finish date.

Stakeholder Management

The process of identifying, analyzing, planning, and engaging individuals or groups who have an interest in or influence over a project. Effective stakeholder management ensures expectations are aligned and resistance is minimized.

Risk Management

The systematic process of identifying, analyzing, prioritizing, and responding to project risks. Risks are uncertain events that, if they occur, could have positive or negative effects on project objectives. Common response strategies include avoidance, mitigation, transfer, and acceptance.

Agile Methodology

An iterative and incremental approach to project management that emphasizes flexibility, collaboration, customer feedback, and rapid delivery of working products. Agile frameworks include Scrum, Kanban, and Extreme Programming (XP).

Earned Value Management (EVM)

A project performance measurement technique that integrates scope, schedule, and cost data to assess project health. It compares the planned value of work with the actual cost and the earned value of work completed to identify variances and forecast outcomes.

Change Management

The formal process for evaluating, approving, and implementing changes to a project's scope, schedule, or budget. A change control board (CCB) typically reviews change requests to assess their impact before authorization.

Project Charter

A formal document that authorizes the existence of a project and provides the project manager with the authority to apply organizational resources. It defines the project's purpose, objectives, high-level requirements, key stakeholders, and initial budget and timeline.

Lessons Learned

The documented knowledge gained through the experience of a project, capturing what went well, what went wrong, and what should be done differently in future projects. This is a critical component of organizational process assets and continuous improvement.

Key Terms at a Glance

Agile:An iterative approach to project management and software development that delivers work in small increments, emphasizing collaboration and adaptability.

Baseline:The approved version of the project plan (scope, schedule, or cost) used as a reference point for measuring performance and managing changes.

Change Control:A systematic process for managing all changes to the project scope, schedule, or cost, ensuring each change is formally evaluated and approved.

Critical Path:The longest sequence of dependent activities that determines the shortest possible project duration.

Deliverable:Any unique and verifiable product, result, or capability produced to complete a process, phase, or project.

Earned Value (EV):The measure of work performed expressed in terms of the budget authorized for that work. A core component of Earned Value Management.

Float (Slack):The amount of time an activity can be delayed without delaying the project completion date or violating a schedule constraint.

Gantt Chart:A type of bar chart that illustrates a project schedule, showing task durations, start and end dates, dependencies, and progress.

Iteration:A time-boxed cycle of development in which a set of features is designed, built, and tested, producing a working increment.

Kanban:A visual workflow management method that uses boards and cards to represent work items, with explicit limits on work in progress.

Kickoff Meeting:A meeting held at the start of a project or phase to align stakeholders on objectives, scope, roles, responsibilities, and communication protocols.

Milestone:A significant point or event in the project timeline, often marking the completion of a major deliverable or decision point. Has zero duration.

PMBOK Guide:The Project Management Body of Knowledge published by PMI, providing standard terminology, processes, and guidelines for project management.

Product Backlog:An ordered list of all features, fixes, and technical work needed in a product, managed by the Product Owner in Scrum.

Program:A group of related projects, subsidiary programs, and program activities managed in a coordinated manner to obtain benefits not available from managing them individually.
