Work Breakdown Structure (WBS)

A hierarchical decomposition of the total scope of work into smaller, manageable deliverables. Each descending level represents increasing detail, and the lowest items, called work packages, can be estimated, scheduled, and assigned.

Related: Critical Path Method, Scope Creep
Critical Path Method

A scheduling technique that identifies the longest sequence of dependent tasks through a project network. Any delay on this path directly delays the project finish date, so it determines the shortest possible duration.

Related: Work Breakdown Structure (WBS), Earned Value Management
Earned Value Management (EVM)

A performance measurement method that compares planned value, earned value, and actual cost to assess project scope, schedule, and cost status. Derived indices and variances reveal whether work is ahead, behind, or on budget.

Related: Critical Path Method, Project Charter
Project Charter

A document that formally authorizes a project and gives the project manager authority to apply organizational resources. It states purpose, objectives, high-level scope, key stakeholders, and the assigned project manager.

Related: Scope Creep, Earned Value Management
Scope Creep

Uncontrolled expansion of project scope without corresponding adjustments to time, cost, or resources. It typically arises from unmanaged change requests and erodes schedule and budget performance.
