Data Date refers to the date up to or through which the project’s reporting system has provided actual status and accomplishments. It is also known as of-date and time-now date.
Decision Tree Analysis:
Decision Tree Analysis refers to a diagram that describes a decision under consideration and the implications of choosing one or another of the available alternatives. It is used when some future scenarios or outcomes of actions are uncertain. It incorporates probabilities and the costs or reward of each logical path of events and future decisions, and uses expected monetary value analysis to help the organization identify the relative values of alternate actions. See also expected monetary value analysis.
Decomposition is a planning technique that subdivides the project scope and project deliverables into smaller, more manageable components, until the project work associated with accomplishing the project scope and providing the deliverables is defined in sufficient detail to support executing, monitoring, and controlling the work.
Defect is an imperfection or deficiency in a project component where that component does not meet its requirements or specifications and needs to be either repaired or replaced.
Defect Repair refers to the formally documented identification of a defect in a project component with a recommendation to either repair the defect or completely replace the component.
Define Activities refers to the process of identifying the specific actions to be performed to produce the project deliverables.
Define Scope refers to the process of developing a detailed description of the project and product.
Deliverable refers to any unique and verifiable product, result, or capability to perform a service that must be produced to complete a process, phase, or project. It is often used more narrowly in reference to an external deliverable, which is a deliverable that is subject to approval by the project sponsor or customer. See also product and result.
Delphi Technique is an information gathering technique used as a way to reach a consensus of experts on a subject. Experts on the subject participate in this technique anonymously. A facilitator uses a questionnaire to solicit ideas about the important project points related to the subject. The responses are summarized and are then re-circulated to the experts for further comment. Consensus may be reached in a few rounds of this process. The Delphi technique helps reduce via in the data and keeps any one person from having undue influence on the outcome.

Failure Mode and Effect Analysis (FMEA):
Failure Mode and Effect Analysis is an analytical procedure in which in each potential failure mode in every component of a product is analyzed to determine its effect on the reliability of that component and, by itself or in combination with other possible failure modes, on the reliability of the product or system and on the required function of the component; or the examination of a product (at the system and/or lower levels) for all ways that a failure may occur. For each potential failure, an estimate is made of its effect on the total system and of its impact. In addition, a review is undertaken of the action planned to minimize the probability of failure and to minimize its effects.

Late Finish Date (LF):
Late Finish Date in the critical path method, the latest possible point in time that a schedule activity may be completed based upon the schedule network logic, the project completion date, and any constraints assigned to the schedule activities without violating a schedule constraint or delaying the project completion date.
