Design Review
A design review is a milestone within a product development process whereby a design is evaluated against its requirements in order to verify the outcomes of previous activities and identify issues before committing to—and, if need be, to re-prioritise—further work. The ultimate design review, if successful, therefore triggers the product launch or product release. The conduct of design reviews is compulsory as part of design controls, when developing products in certain regulated contexts such as medical devices. By definition, a review must include persons who are external to the design team. Contents of a design review In order to evaluate a design against its requirements, a number of means may be considered, such as: *Physical tests. *Engineering simulations. *Examinations (Walk-through). Timing of design reviews Most formalised systems engineering processes recognise that the cost of correcting a fault increases as it progresses through the development process. Addi ...

United States Department Of Defense
The United States Department of Defense (DoD, USDOD or DOD) is an executive branch department of the federal government charged with coordinating and supervising all agencies and functions of the government directly related to national security and the United States Armed Forces. The DoD is the largest employer in the world, with over 1.34 million active-duty service members (soldiers, marines, sailors, airmen, and guardians) as of June 2022. The DoD also maintains over 778,000 National Guard and reservists, and over 747,000 civilians bringing the total to over 2.87 million employees. Headquartered at the Pentagon in Arlington, Virginia, just outside Washington, D.C., the DoD's stated mission is to provide "the military forces needed to deter war and ensure our nation's security". The Department of Defense is headed by the secretary of defense, a cabinet-level head who reports directly to the president of the United States. Beneath the Department of Defense are th ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Product Development
In business and engineering, new product development (NPD) covers the complete process of bringing a new product to market, renewing an existing product or introducing a product in a new market. A central aspect of NPD is product design, along with various business considerations. New product development is described broadly as the transformation of a market opportunity into a product available for sale. The products developed by an organisation provide the means for it to generate income. For many technology-intensive firms their approach is based on exploiting technological innovation in a rapidly changing market. The product can be tangible (something physical which one can touch) or intangible (like a service or experience), though sometimes services and other processes are distinguished from "products". NPD requires an understanding of customer needs and wants, the competitive environment, and the nature of the market. Cost, time, and quality are the main variables that driv ...

Design
A design is a plan or specification for the construction of an object or system or for the implementation of an activity or process or the result of that plan or specification in the form of a prototype, product, or process. The verb ''to design'' expresses the process of developing a design. In some cases, the direct construction of an object without an explicit prior plan (such as in craftwork, some engineering, coding, and graphic design) may also be considered to be a design activity. The design usually has to satisfy certain goals and constraints; may take into account aesthetic, functional, economic, or socio-political considerations; and is expected to interact with a certain Environment (systems), environment. Typical examples of designs include architectural drawing, architectural and engineering drawing, engineering drawings, circuit diagrams, Pattern (sewing), sewing patterns and less tangible artefacts such as business process models. Designing People who produce designs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Requirements Analysis
In systems engineering and software engineering, requirements analysis focuses on the tasks that determine the needs or conditions to meet the new or altered product or project, taking account of the possibly conflicting requirements of the various stakeholders, ''analyzing, documenting, validating and managing'' software or system requirements. Requirements analysis is critical to the success or failure of a systems or software project. The requirements should be documented, actionable, measurable, testable, traceable, related to identified business needs or opportunities, and defined to a level of detail sufficient for system design. Overview Conceptually, requirements analysis includes three types of activities: * Eliciting requirements: (e.g. the project charter or definition), business process documentation, and stakeholder interviews. This is sometimes also called requirements gathering or requirements discovery. *Recording requirements: Requirements may be document ...

Design Controls
Design controls designates the application of a formal methodology to the conduct of product development activities. It is often mandatory (by regulation) to implement such practice when designing and developing products within regulated industries (e.g. medical devices). Medical devices Since 1990, the Food and Drug Administration (FDA) has required that medical device manufacturers that want to market certain categories of medical devices in the USA follow Design Control requirements (21 CFR 820.30). At a high level, this regulation requires: * Design and development planning * Design input, including intended use and user needs (also known as customer attributes) * Design output, including evaluation of conformance to design input requirements through: ** Design verification confirming that the design output meets the design input requirements ("did we design the device right?") ** Design validation ensuring that the devices conform to defined user needs and intended uses ( ...
