System Requirements Review
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 D ...

United States Military
The United States Armed Forces are the military forces of the United States. The armed forces consists of six service branches: the Army, Marine Corps, Navy, Air Force, Space Force, and Coast Guard. The president of the United States is the commander-in-chief of the armed forces and forms military policy with the Department of Defense (DoD) and Department of Homeland Security (DHS), both federal executive departments, acting as the principal organs by which military policy is carried out. All six armed services are among the eight uniformed services of the United States. From their inception during the American Revolutionary War, the U.S. Armed Forces have played a decisive role in the history of the United States. They helped forge a sense of national unity and identity through victories in the First Barbary War and the Second Barbary War. They played a critical role in the American Civil War, keeping the Confederacy from seceding from the republic and preserving the unio ...

Non-functional Requirements
In systems engineering and requirements engineering, a non-functional requirement (NFR) is a requirement that specifies criteria that can be used to judge the operation of a system, rather than specific behaviours. They are contrasted with functional requirements that define specific behavior or functions. The plan for implementing ''functional'' requirements is detailed in the system ''design''. The plan for implementing ''non-functional'' requirements is detailed in the system ''architecture'', because they are usually architecturally significant requirements. Definition Broadly, functional requirements define what a system is supposed to ''do'' and non-functional requirements define how a system is supposed to ''be''. Functional requirements are usually in the form of "system shall do ", an individual action or part of the system, perhaps explicitly in the sense of a mathematical function, a black box description input, output, process and control functional model or IP ...

Project Management
Project management is the process of leading the work of a team to achieve all project goals within the given constraints. This information is usually described in project documentation, created at the beginning of the development process. The primary constraints are scope, time, and budget. The secondary challenge is to optimize the allocation of necessary inputs and apply them to meet pre-defined objectives. The objective of project management is to produce a complete project which complies with the client's objectives. In many cases, the objective of project management is also to shape or reform the client's brief to feasibly address the client's objectives. Once the client's objectives are clearly established, they should influence all decisions made by other people involved in the project – for example, project managers, designers, contractors, and subcontractors. Ill-defined or too tightly prescribed project management objectives are detrimental to decision-maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technical Peer Review
In engineering, technical peer review is a type of engineering review. Technical peer reviews are a well defined review process for finding and fixing defects, conducted by a team of peers with assigned roles. Technical peer reviews are carried out by peers representing areas of life cycle affected by material being reviewed (usually limited to 6 or fewer people). Technical peer reviews are held within development phases, between milestone reviews, on completed products or completed portions of products. A technical peer review may also be called an ''engineering peer review'', a ''product peer review'', a ''peer review/inspection'' or an ''inspection.'' Overview The purpose of technical peer reviews is to remove defects as early as possible in the development process. By removing defects at their origin (e.g., requirements and design documents, test plans and procedures, software code, etc.), technical peer reviews prevent defects from propagating through multiple phases and wo ...

Engineering Design Process
The engineering design process is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative - parts of the process often need to be repeated many times before another can be entered - though the part(s) that get iterated and the number of such cycles in any given project may vary. It is a decision making process (often iterative) in which the basic sciences, mathematics, and engineering sciences are applied to convert resources optimally to meet a stated objective. Among the fundamental elements of the design process are the establishment of objectives and criteria, synthesis, analysis, construction, testing and evaluation. Common stages of the engineering design process It's important to understand that there are various framings/articulations of the engineering design process. Different terminology employed may have varying degrees of overlap, which affects what steps get stated explicitly or deemed "high level ...

System Design Review
A System Design Review (SDR) is a scheduled review of many government-contractor relations, which ensures continuous involvement throughout a program. The SDR was originally defined in the Air Force's MIL-STD-1521. The SDR is a technical review conducted to evaluate the manner in which a project's system requirements have been allocated to configuration items, manufacturing considerations, next phase planning, production plans, and the engineering process that produced the allocation. This review is conducted when the system definition is at a point where system characteristics and configuration items are defined. A successful SDR establishes a 'functional baseline'. The MIL-STD-1521 was cancelled in 1995 without replacement for the SDR material. Since that time, the DoD 5000 system has been created which uses technical reviews as described in Chapter 4 of the Defense Acquisition Guide discussions on their role or shown in the diagram of the Integrated Defense Acquisition, Tech ...

Functional Requirements
In software engineering and systems engineering, a functional requirement defines a function of a system or its component, where a function is described as a specification of behavior between inputs and outputs. Functional requirements may involve calculations, technical details, data manipulation and processing, and other specific functionality that define what a system is supposed to accomplish. Behavioral requirements describe all the cases where the system uses the functional requirements, these are captured in use cases. Functional requirements are supported by non-functional requirements (also known as "quality requirements"), which impose constraints on the design or implementation (such as performance requirements, security, or reliability). Generally, functional requirements are expressed in the form "system must do ," while non-functional requirements take the form "system shall be ." The plan for implementing functional requirements is detailed in the system design, whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...

Independent Reviewer
An independent reviewer is an individual who does not have direct professional responsibility for the design stage under review, assuring an independent and objective review. Within the context of formal design reviews, the practical solution is simply to ensure a fresh perspective, based on the principle that those who are too close to the design may overlook design errors. Thus, reviewers should not have been significantly involved in the activities under review. US Food and Drug Administration The US Food and Drug Administration requires that developers of medical device follow a system of design controls. A key part of this system is design review, defined in 21CFR820.3 section (h) as "a documented, comprehensive, systematic examination of the design to evaluate the adequacy of the design requirements, to evaluate the capability of the design to meet these requirements, and to identify problems." In section (e), it is stated that an independent reviewer is required for any desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
