Functional Specifications Document
A functional specification (also, ''functional spec'', ''specs'', ''functional specifications document (FSD)'', ''functional requirements specification'') in systems engineering and software development is a document that specifies the functions that a system or component must perform (often part of a requirements specification) (ISO/IEC/IEEE 24765-2010). The documentation typically describes what is needed by the system user as well as requested properties of inputs and outputs (e.g. of the software system). A functional specification is the more technical response to a matching requirements document, e.g. the Product Requirements Document "PRD". Thus it picks up the results of the requirements analysis stage. On more complex systems multiple levels of functional specifications will typically nest to each other, e.g. on the system level, on the module level and on the level of technical details. Overview A functional specification does not define the inner workings of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specification And Levels Of Development
A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service. A specification is often a type of technical standard. There are different types of technical or engineering specifications (specs), and the term is used differently in different technical contexts. They often refer to particular documents, and/or particular information within them. The word ''specification'' is broadly defined as "to state explicitly or in detail" or "to be specific". A requirement specification is a documented requirement, or set of documented requirements, to be satisfied by a given material, design, product, service, etc. It is a common early part of engineering design and product development processes in many fields. A functional specification is a kind of requirement specification, and may show functional block diagrams. A design or product specification describes the features of the ''solutions'' for the Requirement Specification, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extensible Firmware Interface
UEFI (Unified Extensible Firmware Interface) is a set of specifications written by the UEFI Forum. They define the architecture of the platform firmware used for booting and its interface for interaction with the operating system. Examples of firmware that implement these specifications are AMI Aptio, Phoenix SecureCore, TianoCore EDK II and InsydeH2O. UEFI replaces the BIOS which was present in the boot ROM of all personal computers that are IBM PC-compatible, although it can provide backwards compatibility with the BIOS using CSM booting. Intel developed the original ''Extensible Firmware Interface'' (''EFI'') specifications. Some of the EFI's practices and data formats mirror those of Microsoft Windows. In 2005, UEFI deprecated EFI 1.10 (the final release of EFI). UEFI is independent of platform and programming language, but C (programming language), C is used for the reference implementation TianoCore EDKII. History The original motivation for EFI came during early dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Systems Engineering
Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design, integrate, and manage complex systems over their enterprise life cycle, life cycles. At its core, systems engineering utilizes systems thinking principles to organize this body of knowledge. The individual outcome of such efforts, an engineered system, can be defined as a combination of components that work in synergy to collectively perform a useful Function (engineering), function. Issues such as requirements engineering, reliability, logistics, coordination of different teams, testing and evaluation, maintainability and many other Discipline (academia), disciplines necessary for successful system design, development, implementation, and ultimate decommission become more difficult when dealing with large or complex projects. Systems engineering deals with work-processes, optimization methods, and risk management tools in such projects. It overlaps technical ...

Verification And Validation (software)
Verify or verification may refer to: General * Verification and validation, in engineering or quality management systems, is the act of reviewing, inspecting or testing, in order to establish and document that a product, service or system meets regulatory or technical standards ** Verification (spaceflight), in the space systems engineering area, covers the processes of qualification and acceptance * Verification theory, philosophical theory relating the meaning of a statement to how it is verified * Third-party verification, use of an independent organization to verify the identity of a customer * Authentication, confirming the truth of an attribute claimed by an entity, such as an identity * Forecast verification, verifying prognostic output from a numerical model * Verifiability (science), a scientific principle * Verification (audit), an auditing process Computing * Punched card verification, a data entry step performed after keypunching on a separate, keyboard-equipped ma ...

Software Development Process
In software engineering, a software development process is a process of dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design, product management. It is also known as a software development life cycle (SDLC). The methodology may include the pre-definition of specific deliverables and artifacts that are created and completed by a project team to develop or maintain an application. Most modern development processes can be vaguely described as agile. Other methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, and extreme programming. A life-cycle "model" is sometimes considered a more general term for a category of methodologies and a software development "process" a more specific term to refer to a specific process chosen by a specific organization. For example, there are many specific software development processes that fit the spiral ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benchmarking
Benchmarking is the practice of comparing business processes and performance metrics to industry bests and best practices from other companies. Dimensions typically measured are quality, time and cost. Benchmarking is used to measure performance using a specific indicator (cost per unit of measure, productivity per unit of measure, cycle time of x per unit of measure or defects per unit of measure) resulting in a metric of performance that is then compared to others. Also referred to as "best practice benchmarking" or "process benchmarking", this process is used in management in which organizations evaluate various aspects of their processes in relation to best-practice companies' processes, usually within a peer group defined for the purposes of comparison. This then allows organizations to develop plans on how to make improvements or adapt specific best practices, usually with the aim of increasing some aspect of performance. Benchmarking may be a one-off event, but is often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Product Design Specification
A design specification is a detailed document that sets out exactly what a product or a process should present. For example, the design specification could include required dimensions, environmental factors, ergonomic factors, aesthetic factors, maintenance that will be needed, etc. It may also give specific examples of how the design should be executed, helping others work properly (a guideline for what the person should do). Example of a design specification An example design specification is shown below. Columns and information may be adjustable based on the output format (may be a physical product, or software, etc.) See also * Data sheet (Spec sheet) * Design by contract * Software requirements specification * Specification A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service.

Diagnostic Design Specification
Diagnostic design specification is a document indicating how the diagnostics will be implemented on upcoming/new products that will be developed by the company. It describes the behavior of the diagnostics like how the test will execute, how the output messages are formatted, and how the final result is displayed (among others). This document is usually defined by the manufacturing team (more specifically, the manufacturing test engineers) and will be submitted to the software-diagnostic group for approvals. In reality, not all the specifications can be delivered on time for the build-up of the first prototype boards so all the tests defined in the document usually are given in phases. Once both teams agree on the delivery timeline, the document is signed by both teams and put into some kind of document control. It is possible that the document may be changed from time to time like when other teams introduce new components or remove them. References See also * Functional specifi ...

Bit Specification (other)
{{disambig ...
In computing, bit specification may mean: * Computer hardware or software capabilities or design features expressed in terms of bit counts. Higher bit specification (e.g. ''16-bit'' vs. ''8-bit'') usually indicates better performance. Examples: ** Color depth ** Computer bus size ** Processor register size ** Sound quality * Specification or datasheet where the meaning of individual bits in a larger, for example byte-length, message is described. Bit specifications are often required to document low-level device control or data transmission protocols. See bit manipulation.
