Work Breakdown Structure
A work-breakdown structure (WBS) in project management and systems engineering is a breakdown of a project into smaller components. It is a key project management element that organizes the team's work into manageable sections. The Project Management Body of Knowledge defines the work-breakdown structure as a "hierarchical decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and create the required deliverables." A WBS provides the necessary framework for detailed cost estimation and control while providing guidance for schedule development and control.Booz, Allen & HamiltoEarned Value Management Tutorial Module 2: Work Breakdown Structure science.energy.gov.

Product Breakdown Structure
{{more citations needed, date=January 2021 In project management under the PRINCE2 methodology, a product breakdown structure (PBS) is a tool for analysing, documenting and communicating the outcomes of a project, and forms part of the product based planning technique. The PBS provides "an exhaustive, hierarchical tree structure of deliverables that make up the project, arranged in whole-part relationship" (Haughey, 2015).Duncan Haughey. (2015) ‘Project Management Tools’, Project Smart. Available from: https://www.projectsmart.co.uk/project-management-tools.php Comparison with the work breakdown structure The PBS is identical in format to the work breakdown structure (WBS), but is a separate entity and is used at a different step in the planning process. The PBS precedes the WBS and focuses on cataloguing all the desired outputs (products) needed to achieve the goal of the project. This feeds into creation of the WBS, which identifies the tasks and activities required to deli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terminal Element
In category theory, a branch of mathematics, an initial object of a category is an object in such that for every object in , there exists precisely one morphism . The dual notion is that of a terminal object (also called terminal element): is terminal if for every object in there exists exactly one morphism . Initial objects are also called coterminal or universal, and terminal objects are also called final. If an object is both initial and terminal, it is called a zero object or null object. A pointed category is one with a zero object. A strict initial object is one for which every morphism into is an isomorphism. Examples * The empty set is the unique initial object in Set, the category of sets. Every one-element set ( singleton) is a terminal object in this category; there are no zero objects. Similarly, the empty space is the unique initial object in Top, the category of topological spaces and every one-point space is a terminal object in this category. * In ...

Feature-driven Development
Feature-driven development (FDD) is an iterative and incremental software development process. It is a lightweight or agile method for developing software. FDD blends several best practices into a cohesive whole. These practices are driven from the perspective of delivering functionality ( features) valued by the client. Its main purpose is to deliver tangible, working software repeatedly in a timely manner in accordance with the Principles behind the agile manifesto. History FDD was initially devised by Jeff De Luca to meet the specific needs of a 15-month, 50-person software development project at a large Singapore bank in 1997. This resulted in a set of five processes that covered the development of an overall model and the listing, planning, design, and building of features. The first process is heavily influenced by Peter Coad's approach to object modeling. The second process incorporates Coad's ideas of using a feature list to manage functional requirements and develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Design Review (US Government)
In the United States military integrated acquisition lifecycle the technical section has multiple acquisition technical reviews. Technical reviews and audits assist the acquisition and the number and types are tailored to the acquisition. Overall guidance flows from the Defense Acquisition Guidebook chapter 4, with local details further defined by the review organizations. Typical topics examined include adequacy of program/contract metrics, proper staffing, risks, budget, and schedule. In NASA's engineering design life cycle, design reviews are held for technical and programmatic accountability and to authorize the release of funding to a project. A design review provides an in-depth assessment by an independent team of discipline experts and managers that the design (or concept) is realistic and attainable from a programmatic and technical sense. Design review is also required of medical device developers as part of a system of design controls described in the US Food and Drug ...

Exit-criteria
Exit criteria are the criteria or requirements which must be met to complete a specific task or process as used in some fields of business or science, such as software engineering. Usage The term exit criteria is often used in research and development, but it could be applicable to any field where business process reengineering is (or could be) applied. The benefits of business process re-engineering — including the use of terms such as this one — could include: understanding goals clearly; using language (and data) carefully when talking about (or measuring) methods for getting things done; and taking a scientific approach towards evaluating and improving the methods that are used. For example, for Fagan inspection, the low-level document must comply with specific exit criteria (as specified in the high-level document) before the development process can be taken to the next phase. In telecommunications, when testing new software Software consists of computer programs th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mutually Exclusive
In logic and probability theory, two events (or propositions) are mutually exclusive or disjoint if they cannot both occur at the same time. A clear example is the set of outcomes of a single coin toss, which can result in either heads or tails, but not both. In the coin-tossing example, both outcomes are, in theory, collectively exhaustive, which means that at least one of the outcomes must happen, so these two possibilities together exhaust all the possibilities. However, not all mutually exclusive events are collectively exhaustive. For example, the outcomes 1 and 4 of a single roll of a six-sided die are mutually exclusive (both cannot happen at the same time) but not collectively exhaustive (there are other possible outcomes; 2,3,5,6). Logic In logic, two propositions \phi and \psi are mutually exclusive if it is not logically possible for them to be true at the same time; that is, \lnot (\phi \land \psi) is a tautology. To say that more than two propositions are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Military Standard
A United States defense standard, often called a military standard, "MIL-STD", "MIL-SPEC", or (informally) "MilSpecs", is used to help achieve standardization objectives by the United States Department of Defense. Standardization is beneficial in achieving interoperability, ensuring products meet certain requirements, commonality, reliability, total cost of ownership, compatibility with logistics systems, and similar defense-related objectives. Defense standards are also used by other non-defense government organizations, technical organizations, and industry. This article discusses definitions, history, and usage of defense standards. Related documents, such as defense handbooks and defense specifications, are also addressed. Definition of document types Although the official definitions differentiate between several types of documents, all of these documents go by the general rubric of "military standard", including defense specifications, handbooks, and standards.

MITRE Corporation
The Mitre Corporation (stylized as The MITRE Corporation and MITRE) is an American not-for-profit organization with dual headquarters in Bedford, Massachusetts, and McLean, Virginia. It manages federally funded research and development centers (FFRDCs) supporting various U.S. government agencies in the aviation, defense, healthcare, homeland security, and cybersecurity fields, among others. MITRE formed in 1958 as a military think tank, spun out from the radar and computer research at the MIT Lincoln Laboratory. Over the years, MITRE's field of study had greatly diversified. In the 1990s, with the winding down of the Cold War, private companies complained that MITRE had an unfair advantage competing for civilian contracts; in 1996 this led to the civilian projects being spun off to a new company, Mitretek. Mitretek was renamed Noblis in 2007. Etymology The name MITRE was created by James McCormack Jr., one of the original board members. The name is not an acronym, althoug ...
