Abstract
GxP critical spreadsheets need to undergo specification to ensure that the user's needs and the spreadsheet's functionality is clearly defined and documented.
This paper describes a pragmatic approach to the specification of Excel spreadsheets using a single generic document. The approach described is easily transferred to other simple systems such as databases and standalone instrumentation.
This continues the series of short articles describing a generic process for validating Excel Spreadsheets. A previous article gave an overview to the process, whilst a subsequent topic will cover the testing and qualification.

- Appendix A – User requirements table details.
- Appendix B – Functional specification and worksheet contents.
