Detailed Engineering

The phase of engineering following basic engineering after approval has been given for the project. Provides the specifications and construction drawings which detail all engineering aspects for the construction of a project. [D04966]

Detailed Estimate

An estimate based on complete or nearly complete details of quantity, specifications, conditions and the like. Suitable for major commitments, cost tracking and control. Also known as Definitive Estimate, or "bottom up estimate". [D05158]

Detailed Planning

The lowest level of planning adopted in a project. [D00527]

Detailed Plans

See Detailed Resource Plan and Detailed Technical Plan. [D00528]

Detailed Resource Plan

A plan implemented when it is 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. [D00529]

Detailed Schedule

A plan of activities for all work. The detailed schedule would typically cover activities up to at least the next major milestone. The detailed schedule supports and is consistent with the Master Schedule.
Editor's Note: See also Short Term Plan. [D02261]

Detailed Technical Plan

A plan providing a detailed breakdown of selected major activities, e.g. system testing, and produced as and when required. A Detailed Technical Plan should be established on all but the very smallest projects. [D03835]

A plan used to give a specific breakdown of major activities. It exists in all but the smallest projects. [D00530]

Determination

Arrival at a conclusion, or firm resolution to do so. [D02656]

Determine Least Cost for Maximum Results

See Cost benefit. [D02657]

Deterministic

An approach that presumes the presence of fixed constraints. [D02658]

Deterministic Network

A network with no facilities to accommodate probabilistic dependencies. Precedence networks are said to be deterministic. [D00531]

Both activity on arrow and precedence networks are said to be deterministic since they have no facilities to accommodate probabilistic dependencies. [D03836]

Developed Country

A term used generally to refer to a country having the advanced technology of the "western world". [D02659]

Developer

A person responsible for developing the required functionality in accordance with project-adopted standards and procedures. This can include performing activities in any of the requirements, analysis and design, implementation, and test workflows. [D04720]

Developing Country

A term used generally to refer to a country still aspiring to the advanced technology of the "western world". [D02660]

Development

The process of working out and extending the theoretical, practical, and/or useful application of an idea, concept, or preliminary design. [D02307]

See Development Phase [D02180]

The systematic use, under whatever name, of scientific and technical knowledge in the design, development, test, or evaluation of a potential new product or service (or of an improvement in an existing product or service) for the purpose of meeting specific performance requirements or objectives. Development includes the functions of design engineering, prototyping, and engineering testing. [D03496]

Development Case

The software-engineering process used by the performing organization. It is developed as a configuration, or customization, of the Unified Process product, and adapted to the project's needs. [D04721]

Development Phase

The second of four sequential phases in the generic project life cycle. Also known as planning phase or definition phase. [D00533]

A software life cycle period that contains the activities of requirements analysis, design, coding, integration, testing, integration and acceptance support of software products. [D00532]

Also called the feasibility phase. That part of a project life cycle comprising feasibility studies, if required, planning, engineering or development, after which a capital appropriation request is made, supported by a project brief. See also implementation phase. [D00534]

Development Plan

A plan for moving a project concept to a viable project. [D02843]

Development process

A set of partially ordered steps performed for a given purpose during software development, such as constructing models or implementing models. [D04722]

Deviation

A departure from established requirements. Deviations occur when the work product either fails to meet or unnecessarily exceeds the requirements. [D00537]

Difference (from a project plan, budget, etc.) [D00535]

Written authorization, granted prior to the manufacture of an item, to depart from a particular performance or design requirement of a contract, specification, or referenced document, for a specific number of units or specific period of time. [D00536]

Any variation from planned performance. The deviation can be in terms of schedule, cost, performance, or scope of work. Deviation analysis is the heart of exercising project control. [D03716]

The change, plus or minus, from a control estimate or control curve. [D04967]

A noticeable or marked departure from the appropriate norm, plan, standard, procedure, or variable being reviewed. [D05174]

Deviation Permit

See Production Permit [D01296]

Diagram

A graphical depiction of all or part of a model. [D04825]

Diagramming

See scheduling. [D02661]

DID

See Data Item Description

Differences

Either

1. Elements of disagreement or in dispute, having variations, or otherwise dissimilar, or
2. The subtraction of one amount from another corresponding amount.

[D02662]

Differentials

The amounts by which variable quantities differ. [D02663]

Differing Site Conditions

Generally refers to either a subsurface or latent physical condition at the site which differs materially from the conditions shown or indicated in the contract documents. It may also include an unknown physical condition at the site, of an unusual nature, differing materially from conditions generally encountered and recognized as inherent in the work described by the contract documents. [D04968]

Direct Cost

Any cost that is specifically identified with a particular Activity. See also Direct Project Costs [D00538]

Direct Cost Contingency

See Project Direct Cost Contingency. [D03786]

Direct Costs

Costs that are specifically attributable to an activity or group of activities without apportionment. [D04426]

Those costs (labor, material, and other direct costs) that can be consistently related to work performed on a particular project. Direct costs are best contrasted with indirect costs that cannot be identified to a specific project. [D00539]

Direct Labor

Labor, i.e. man-hours, that is specifically identified with a particular Activity. [D02308]

Direct Project Costs

The costs directly attributable to a project, including all personnel, goods and/or services together with all their associated costs, but not including indirect project costs, such as any overhead and office costs incurred in support of the project. [D00540]

Directing

The provision of instructions with a view to achieving a project goal or objective. [D02664]

The implementation and carrying out (through others) of those approved plans that are necessary to achieve or exceed project objectives. Generally of such broad and nonspecific nature that considerable judgment must be used in making decisions concerning the scope and frequency of demands. Directing encompasses: training; supervising; delegating; motivating; counseling; and coordinating. [D02666]

Direction

The way in which managers pass orders to subordinates. [D02667]

Directive

An instruction pursuant to a project objective. [D02665]

Director

A level in a management hierarchy. [D04077]

Discipline

A broad general body of knowledge, skills and competence (expertise) that logically belong together and which are required by a company in order to provide its products or service, or to provide other functions necessary for its continued existence. [D03620]

The sequence of activities performed in a business that produces a result of observable value to an individual actor of the business. [D04900]
