Do-minimum option
The Green Book, Central Government Guidance On Appraisal And Evaluation, Published by HM Treasury in 2020, suggests the do-minimum option in the Green Book: ‘…refers to the minimum intervention required to deliver the core business needs required to deliver the SMART objectives identified in the strategic appraisal. This excludes additional features that take advantage of opportunities present during implementation of change.’
The 2018 Green Book defined the do-minimum option as: ‘…the minimum intervention required to deliver core objectives. This excludes any additional features that may also be possible and bring additional benefits.’
