The Strategic Outline Case (SOC) sets out the foundation for Flood and Coastal Erosion Risk Management (FCERM) projects. It establishes the case for change, defines the scope, and provides an early indication of suitable measures.

At this stage, the SOC ensures that the project is aligned with investment objectives and supported by a clear understanding of the flooding or erosion challenges.

Economic Case

Assessment of options with a recommended way forward and an initial shortlist for further review at the Outline Business Case (OBC) stage.

Business Justification Case (BJC)

The Business Justification Case (BJC) is a streamlined, single‑stage business case used for smaller, simpler, and less contentious Flood and Coastal Erosion Risk Management (FCERM) projects.

It provides a proportionate framework for developing appropriate flood mitigation schemes, ensuring that investment objectives, costs, risks and benefits are clearly defined. The BJC is particularly suited to projects with lower costs, straightforward delivery routes and limited complexity.

Clear investment objectives and critical success factors

Setting SMART goals and defining the criteria against which options will be assessed.

Proportionate appraisal of options

Considering Walkaway, Business as Usual, and Do Something options, supported by a brief SWOT analysis and performance assessment.

Whole‑life cost and affordability analysis

Summarising capital and revenue costs, identifying funding contributions, and ensuring cost certainty through framework contracts or pre‑competed arrangements.

Management and assurance arrangements

Establishing a project programme, risk register, health and safety measures, and processes for monitoring benefits realisation and lessons learned.
