A technical specification is a document that defines a set of requirements that a product or assembly must meet or exceed. A product or assembly that does not meet all of the specifically expressed requirements does not meet the specification, and often is referred to as being out of specification or "out of spec." Specifications are used when a contract for technical products or services is issued. The technical specification defines the requirements to fulfill the contract.
STEPS:
1
Decide if the specification will be open or closed. * Consider an open specification. An open specification describes required performances without mandating how those performances are to be achieved. An open specification leaves a great deal of freedom to the entity that creates a product or assembly to satisfy the specifications. For example, a computer memory storage specification may not specify the exact medium used to store the data in order to meet the requirement.
* Evaluate a closed specification. A closed specification describes not only required performances, but also tools, technologies or subassemblies that must be used in the design of a product or assembly to meet the specification. For example, a lifting assembly specification may require that hydraulic power be used by the product or assembly that is to meet the specification.
Determine requirements.
> Evaluate all specifications to determine if they are necessary to the product or assembly.
Ascertain your writing style.
> Use short and direct sentences.
> Avoid using "it" or "which", and clearly specify what is being referred to in the text.
> Define the jargon and abbreviations that are common within the industry. To clearly define industry terms, add a definition section at the beginning of the specification.
Develop your table of contents.
> . Order the contents such that general requirements about the product or assembly are presented first, followed by
