1.7 The Green Book will be useful for:
❑ Anyone required to conduct a basic appraisal or evaluation of a policy, project or programme; and,
❑ People seeking to expand their knowledge in this area.
1.8 This guidance applies:
At the start ... to any analysis used to support a government decision to adopt a new policy, or to initiate, renew, expand or re-orientate programmes or projects, which would result in measurable benefits and/ or costs to the public. This is the appraisal part of the process.
And at the finish ... to retrospective analysis of a policy, programme or project at its completion, conclusion or revision. This is the evaluation part of the process.
1.9 The ability to judge how effectively government resources have been expended is essential to their strategic long-term management. Planning for this evaluation should be considered at the time of appraisal.
