A1.14 Documentation requirements will vary according to the size or importance of the appraisal in hand. Whether the proposed expenditure is small or large, it is wise to document each step of the appraisal process as and when it occurs, rather than to defer all the writing up to a later stage.
A1.15 Smaller scale appraisals should generally be documented in a step-by-step record, but need not meet the full requirements demanded of large submissions. For example, while risks and uncertainties and the need for post project evaluation should generally be considered, they may not require substantial documentation in small scale appraisals where these factors are considered unimportant. An appraisal concerning a small purchase may deserve a record extending to only a few pages. However, the key steps referred to at paragraph 4 should generally be recorded even in small expenditure appraisals.
