A provision in the project plan to mitigate cost and/or schedule risk. Often used with a modifier (e.g., Management Reserve, Contingency Reserve) to provide further detail on what types of risk are meant to be mitigated.

JN

 RMW
Resource
Any personnel, material or equipment required for the performance of an activity.
Note: Time is not a resource. It is the measure of the duration for which a resource is needed or used. Also, money is better not thought of as a resource, except in financing. It is better seen as the basis of evaluation of the resources used by an activity or task. [D05089]

J

 PMST
Any variable capable of definition that is required for the completion of an activity and may constrain the project. Resources can be people, equipment, facilities, funding or anything else needed to perform the work of a project.
Note 1: A resource may be non-storable so that its availability has to be renewed for each time period (even if it was not utilized in previous time periods).
Note 2: A resource may be storable so that it remains available unless depleted by usage. Such a resource may also be replenished by activities producing credited and storable resource. [D04499]

J

 APM
BS
Resource Accumulation
Process of accumulating the requirements for each resource to give the total required to date at all times throughout the project. [D04502]

JN

 APM
BS
Resource Aggregation
Summation of the requirements for each resource, and for each time period.
Note: Where the earliest start time of an activity is used alone, it is often termed an "early start" aggregation. Similarly a "late start" aggregation uses the latest start times. [D04500]

JN

 APM
BS
Totaling the requirement for a specific resource. [D01655]

JN

 NPMT
Resource Allocation
The assignment of resources to tasks in a project. [D01657]

GJN
CHMT

 MSP98
Distribution of resources over time or project parts. [D01656]

N

 NPMT
An iterative process of computing the schedule considering the limited availability of certain resources so that both time and cost may be minimized.

Progress on certain types of project can be constrained more by limitations of resources (people, machines, materials and money) than by logical sequence dictated by technical considerations. Generally such projects are "horizontal" e.g. Highway construction, rather than "vertical" e.g. High rise construction, although the latter may be constrained by both considerations. The resource loading required can only be determined after a schedule of activities has been developed. The schedule may then be modified, possibly prolonged, either to reduce the total resources required to complete the project or to "level" out peak demands. This avoids congestion at some times and inefficient resource usage at others. [D03087]


N
CH

 CCCP
The assignment of people, equipment, facilities, or materials to a project. Unless adequate resources are provided, project work cannot be completed on schedule, and resource allocation is a significant component of project scheduling. [D03727]

N

 PPS&C p341
Resource Allocation Process
The scheduling of activities in a network with the knowledge of certain resource constraints and requirements. This process adjusts activity level start and finish dates to conform to resource availability and use. [D01658]

JN

 PMK87
Resource Analysis
A term for resource leveling and resource smoothing. [D01659]

The amount of resource availability for any given allocation period. [D01663]

JN

 PMK87
Resource Breakdown Structure ("RBS")
A feature of hierarchical resources that facilitates both roll-up reporting and summary resource scheduling by enabling you to schedule at the detailed requirements level, and roll up both requirements and availabilities to a higher level. [D01664]

JN

 WST
Resource Buffer
A designed amount of time reserved for resources that may need additional time to run their leg of the relay when their predecessor is complete. Unlike other buffers, they do not directly impact the lead time or scheduling of the project, but rather serve as a wake-up call when needed. [D05584]

JN

 067

A calendar that defines the working and non-working patterns for specific resources. See also Project Calendar. [D01665]

The flattening out of the peaks and valleys of resource requirements so that steady or consistent levels of resources can be used over time. [D06210]

FGJN
CHMT
