- Dangle
- An activity or network which has either no predecessors or no successors. If neither, referred to as an isolated activity.
Source
- Data Type
- The characteristic indicating whether a data item represents a number, date, character string, etc.
Source
- Delaying Resource
- In resource scheduling, inadequate availability of one or more resources may require that the completion of an activity be delayed beyond the date on which it could otherwise be completed. The delaying resource is the first resource on an activity that causes the activity to be delayed.
Source
- Delegating
- The process by which authority and responsibility is distributed from Project Manager to subordinates.
Source

Source
- Delphi Technique
- A process where a consensus view is reached by consultation with experts. Often used as an estimating technique.
Source
- Dependencies
- Dependencies are relationships between products or tasks. For example, one product may be made up of several other ‘dependent’ products or a task may not begin until a ‘dependent’ task is complete. See also logical relationship.
Source
- Dependency Links
- Different types of links connecting activities in a precedence network.
Source
- Design and Development Phase
- The time period in which production process and facility and production processes are developed and designed.
Source
- Detailed Plans

Source
- Detailed Resource Plan
- A plan implemented when it’s necessary to plan and control a certain major activity within a stage. The plan sets costs and resource usage that correspond to the detailed technical plan.
