Step 6: Option generation and appraisal/business case scoping

This final step in the process is concerned with addressing gaps in service provision (under or over-provision) through generating options and scoping the level of proportionate appraisal / business case development that would be required to progress these options. In some cases, an improvement could be delivered through the bi-annual timetable setting process or a simple single stage business case where a small investment is required. Other service changes may require a more detailed appraisal or programme or project business case (e.g., a major service increase or reduction; a new vessel etc). This will have to be determined on a case-by-case basis in each CNA.

The option generation should be split into revenue and capital measures, with the approach adopted for each set out below.
