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. [ 1 ] It is a common early part of engineering design and product development ...
Business requirements, also known as stakeholder requirements specifications (StRS), describe the characteristics of a proposed system from the viewpoint of the system's end user like a CONOPS. Products, systems, software, and processes are ways of how to deliver, satisfy, or meet business requirements. Consequently, business requirements are ...
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
During construction, the architect normally acts as the owner's representative. This includes reviewing the builder's work and ensuring that the products and methods meet specifications and codes. The architect's role is compromised when the architect works for the design-builder and not for the owner directly.
Engineers don’t always follow a smooth flow from step to step even in ordinary manufacturing. Most manufacturing design decisions tends to be highly iterative. [3] It is common to create a design that meets customer approval, test it, make changes to meet specifications, and resubmit at certain stages or milestones in order for approval to proceed to the next stage.
A standard specification is an explicit set of requirements for an item, material, component, system or service. It is often used to formalize the technical aspects of a procurement agreement or contract. [2] For example, there may be a specification for a turbine blade for a jet engine that defines the exact material and performance requirements.
An NC machine alters a blank piece of material (metal, plastic, wood, ceramic, or composite) to meet precise specifications by following programmed instructions and without a manual operator. Coefficient of thermal expansion – describes how the size of an object changes with a change in temperature. Specifically, it measures the fractional ...
The process capability is a measurable property of a process to the specification, expressed as a process capability index (e.g., C pk or C pm) or as a process performance index (e.g., P pk or P pm). The output of this measurement is often illustrated by a histogram and calculations that predict how many parts will be produced out of ...
