Specification Writing

.Writing a specification for the first time may seem a daunting task. However if you follow these simple guidelines the result should be quite sufficient for a fixed price quotation:

  • If you’re going to use terminology specific to a particular field include a glossary.
  • Please incorporate a method of identifying the latest version of a document e.g. a revision number.
  • Many products will need a user guide and/or installation manual. Often these are written last; instead consider writing them first – they will reveal a lot about the product.
  • If using MS Word, consider using Styles as this will enable:
    • Automatic generation of a Table of Contents.
    • Section cross-references that update automatically.
    • Convenient document navigation via the Document Map.

  • Consider what acceptance tests will be required to check the product conforms to the specification.
  • Use natural language to describe what the product is to do:
    • Avoid complex flow-charts; these do not define the problem; rather they describe one particular solution.
    • A common pitfall with follow-on products is to include the techniques used in previous generations as part of the specification for subsequent generations. However, as both engineering practices & technology are constantly evolving, this can stifle innovation.
    • It may seem obvious but don’t describe a product in terms of previous products unless they are familiar to all interested parties.

  • Include any of the following that you’re aware of:
    • Relevant standards.
    • Direct competitors.
