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)
