Glossary of Terms

This glossary contains definitions used by the Project Change Frame® and other methodologies supported by Lindsay McKenna Limited.

A number of definitions are taken from the Project Management Book of Knowledge (PMBOK®) from the Project Managment Institute. These are denoted by having (PMI) at the end of the definition..

Decision Tree Analysis
A diagram that describes a decision under consideration and the implications of choosing one or another of the available alternatives. It incorporates probabilities or risks and the costs or rewards of each logical path of events and future decisions. (PMI)
Define
The first phase in the Six Sigma methodology. In this phase the projects purpose and scope are established.
Deflection
The act of transferring all or part of a risk to another party, usually by some form of contract provision, insurance policy or warranty. Also called risk transference.
Deliverable
  1. Any measurable, tangible, verifiable outcome, result or item that must be produced to complete a project or subproject. (PMI)
  2. Also known as Outputs. The specific, tangible things that people will receive from the project on its completion (what they will see, feel and have as a direct result of the project being achieved). Each key output should be defined in the Project Contract and ideally represented as a milestone in the project plans. (Examples: a report or presentation of the findings and recommendations, a prototype or finished product, a new software application).
Delphi Technique
A form of participative expert judgment, it is an anonymous, interactive forecasting technique used to derive consensus about future events on a project. The purpose of the Delphi technique is to elicit information and judgments from participants to facilitate problem-solving, planning and decision-making. (PMI)
Dependent Activity
See Activity, Dependent.
Directive Approach
Top-down management of change, with little opportunity for Stakeholders to influence or get involved. The focus is on timetables, measurement and plans, and less on the process for getting there.
DMAI2C
Acronym for the 5 phases of the Six Sigma methodology. It stands for Define, Measure, Analyze, Innovative Improvement and Control.
Dummy Activity
  1. Used in network diagrams to demonstrate where one activity is dependent on another.
  2. An activity of zero duration used to show a logical relationship in the arrow diagramming methods. Dummy activities are used when logical relationships cannot be completely or correctly described with regular activity arrows. Dummies are shown graphically as a dashed line headed by an arrow. (PMI)
Duration
  1. The total period of time from the start of an activity through to its completion. This period of time will typically consist of the time required to progress the work to completion (see Effort), plus waiting or "dead" time.
  2. The number of time periods (not including holidays and other non-working periods) required to complete an activity or other project element. Typically expressed as workdays or workweeks. (PMI)
Duration Compression
Shortening the project schedule with reducing project scope. Compression is not always possible and often requires an increase cost. (Crashing utilises duration compression). (PMI)
