Project Dictionary RAM See Responsibility Assignment Matrix RAM See Responsibility/Accountability Matrix Random Observation A technique for building up a picture of an activity by taking sufficient random observations. The alternative is to observe the activity continuously, which may itself influence performance of the activity. Random Sample A sample selected in such a way that each unit of the population has an equal chance of being selected. Range The difference between the highest and lowest observed values in a data set. Ranking Placing in relative standing or position. An orderly hierarchical arrangement according to some identifiable characteristics. Rapid Implementation See Fast Tracking RBS See Resource Breakdown Structure Re-Baseline Development of a revised implementation plan with new milestone schedules. Re-baselining is required in response to changed contract requirements, funding changes, or realization that the operative implementation plan is not achievable. Re-Baselining The process whereby the project's costs, time scale or resources have to be re-calculated due to a change in the project's objectives, a change in the deliverables to meet requirements, or the project's original scope and plans have become untenable. Re-Profiling In resource scheduling it is possible to indicate that the specified resource requirement profile may be modified to fit the availability, without changing the total amount required.Readiness Assessment A meeting or series of meetings by selected members of the customer C/SCSC review team at a contractor's plant, to review contractor plans and progress in implementing C/SCSC in preparation for a full demonstration review. Real TimeThe application of external time constraints which might affect the calendar time position of execution of each activity in the schedule.Real Time Immediate response to an outside stimulus. RecommendTo offer or suggest for use. Recommendation describes the presentation of plans, ideas, or things to others for adoption. To recommend is to offer something with the option of refusal. ReconditionedRestored to the original normal operating condition by readjustments and material replacement. RecordA set of data. Record Drawings Drawings submitted by a contractor or subcontractor to show the construction of a particular structure or work as actually completed. Record RetentionThe necessity to retain records for reference for a specified period after contract close-out, in case they are needed.Recording FactsThe assembly and documentation of explicit data, typically focused on a specific area for resolving a problem or issue. Particularly required in value management or litigation.RecordsThe collection of related items of information assembled during the course of a project. See also Records Management.Records ManagementThe procedures established by an organization to manage all documentation required for the effective development and application of its work force. Recovery ScheduleA special schedule showing special efforts to recover time lost compared to the master schedule. Recruitment, Selection and Job PlacementAttraction of a pool of potential employees, determining which of those employees is best suited for work on the project, and matching that employee to the most appropriate task based on his or her skills and abilities.Recurring CostsExpenditures against specific tasks that would occur on a repetitive basis. Examples are sustaining engineering, production of operational equipment, tool maintenance, etc.Recurring TaskA task that occurs repeatedly during the course of a project, such as a weekly staff meeting. Reduced InspectionInspection under a' sampling plan using the same quality level as for normal inspection, but requiring a smaller sample for inspection.RedundancyDuplication of capability to increase reliability.ReengineeringThe process of completely redesigning a product, system or process to be more effective or efficient.Reference GroupA group of people available for advice, and expecting to be kept informed during project planning and implementation.Refinement, ScheduleThe rework, redefinition or modification of the logic or data that may have previously been developed in the planning process as required to properly input milestones, restraints and priorities.Regression AnalysisA quantitative technique used to establish a line-of-best-fit through a set of data to establish a relationship between one or more independent variable and a dependent variable. That line is then used with a projected value of the independent variable(s) to estimate a value for the dependent variable. Regulatory PersonnelThose individuals working for government regulatory agencies whose task it is to assure compliance with their particular agency's requirements. Reimbursable ExpenditureA seller's expenditure funded by the buyer. Rejection NumberThe minimum number of defects or defective units in the sample that will cause rejection of the lot represented by the sample. RelationshipA logical connection between two activities.Relationship FloatRelationship free float is the amount by which the lag on that relationship would have to be increased in order to delay the successor activity. Relationship total float is the amount by which it would have to be increased in order to cause a delay in the completion of the project as a whole (or the violation of a late target). ReleaseA configuration management action whereby a particular version of hardware, software, or documentation is baselined and made available for general use. Release ClaimsCertificate to release and hold harmless from future claims by the contractor.ReliabilityA fundamental characteristic of an item or material expressed as the probability that it will perform its intended function for a specified time under stated conditions.Reliability AssuranceAll actions necessary to provide adequate confidence that material conforms to established reliability requirements. Remaining Available ResourceThe difference between the resource availability pool and the level schedule resource requirements. Computed from the resource allocation process.Remaining DurationThe estimated work units needed to complete an activity as of the data date.Remaining Float ("RF")The difference between the early finish and the late finish date.Replacement TheoryA statistical methodology for arriving at the optimum life of replaceable elements in a project. It considers replacement cost, maintenance and down time costs, tax implications and scrap value. Replacement ValueThe amount equal to the cost of replacing an item with a new one rather than the depreciated value of the existing one.ReplanSchedule or resource adjustments to meet contract milestones. Replanning does not imply re-baselining. Replanning Actions performed for any remaining effort within project scope. Report A written record or summary. A detailed account or statement. Report Specification File A set of codified instructions, which defines the layout of a report.Reporting Planning activity involved with the development and issuance of (internal) time management analysis reports and (external) progress reports.Request for Appropriation ("RFA")See Capital Appropriation Request. Request for Change A proposal by the project manager for a change to the project as a result of a project issue report. Request for Change ("RFC")A buyer or seller request to spend contract funds on an engineering change proposal for a change. The request states the technical or contractual issue being addressed, the impact on or benefit to the project, and an assessment of the cost and schedule impact.Request for Proposal A formal invitation containing a scope of work which seeks a formal response (proposal) describing both methodology and compensation to form the basis of a contract.Request for Quotation ("RFQ")A formal invitation to submit a price for goods and/or services as specified.Requirement Specification A document containing the full set of product requirements, from the top-level business needs to the detailed technical requirements. Requirements A clear statement of a need, written in such a way that there is no question about what is being asked. For clarification purposes, a modifer should always precede requirements such as user requirements, system requirements, operational requirements, contract requirements, test requirements, etc. Requirements Flowdown The process of deriving and allocating requirements to all levels of system decomposition. Requirements Management The process of defining the user/customer requirements and building the system requirements before going on to develop the performance specifications in detail. Requirements should be comprehensive and clear, well structured, traceable and testable. They should give rise to clearly specified project deliverables and should be tested against the original set of requirements. Any changes to the initial requirements should be traceable i.e. documented and explainable. Requirements Traceability The management of the parent/child relationships of all system requirements. Requirements Traceability Matrix A document that maps the parent-child relationships of requirements. Reschedule The process of changing the logic, duration, and/or dates of an existing schedule in response to external imposed conditions. Rescheduling A feature of most PM software that recalculates the start and finish dates of all uncompleted activities based upon progress as of a specified date. Research and Development Technical pursuit of a new technology or design to support a strategic goal. ReserveA 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. Reserve For Scope Changes A sum of money set aside for changes in the Owner's requirements and to be used only at the direction of the Owner. Residual ValueThe proceeds, less removal and disposal costs, if any, realized upon disposition of a tangible capital asset.Residue File A file in the same format as the resource availability file containing a specification of the resources remaining after a project is scheduled.Resource Any factors such as personnel, equipment, facilities, etc. (except time) required or consumed to accomplish an activity. Resource Aggregation Totaling the requirement for a specific resource. Resource Allocation The assignment of resources to tasks in a project.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. Resource Analysis A term for resource leveling and resource smoothing. Resource Assignment The work on an activity related to a specific resource. Resource Availability The extent to which resources are available to meet the project's needs.Resource Availability Date The calendar date when a resource pool becomes available for a given resource. Resource Availability Pool The amount of resource availability for any given allocation period. 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.
