About the programme
Course Overview
Safety proposals frequently lose out to other capital requests because their benefit is described qualitatively while competing proposals arrive with a quantified return, and many organisations still only track the direct, insured cost of incidents while ignoring the larger indirect costs of lost production, retraining and reputational impact. This course distinguishes direct, indirect and hidden incident costs, and works through building an incident cost model appropriate to the organisation's own operations, wage rates and insurance arrangements. It covers calculating avoided-cost and return-on-investment figures for proposed controls, handling uncertainty and probability honestly rather than presenting a single deterministic number, and structuring a business case in language that finance and operations will actually engage with. Teaching includes an incident cost calculation workshop using representative case data, a business case drafting exercise and a mock investment committee presentation, so participants leave with a completed incident cost model and a business case template ready to apply to a real investment decision.

Incorporate probability and uncertainty into a safety investment case rather than presenting a single deterministic figure.
Present a safety business case persuasively to a budget-holding audience and respond to financial scrutiny.
Track realised savings and performance against the business case after a safety investment is approved and implemented.

01Understanding the True Cost of Workplace Incidents
2 sessions · 8 points
Session 1Direct, Indirect and Hidden Cost Categories
- Identify direct costs, including medical treatment, insurance claims and regulatory fines, that are usually already tracked by finance.
- Identify indirect costs, including lost production time, overtime cover, retraining and equipment damage, that are frequently underestimated.
- Recognise hidden costs, such as reputational damage, reduced morale and increased staff turnover, that rarely appear in an incident report.
- Distinguish insured from uninsured costs to understand which expenses the organisation actually bears after any claim is settled.
Session 2Building an Organisation-Specific Cost Model
- Gather organisation-specific data, including average wage rates, overtime premiums and typical incident investigation time, to ground the model in reality.
- Select representative past incidents to calibrate the cost model rather than relying solely on generic industry cost multipliers.
- Build a spreadsheet or simple tool that calculates total cost per incident type, updated as new incident data becomes available.
- Validate the model against known total costs from a recent significant incident to check its outputs are credible to finance.
02Calculating Return on Safety Investment
2 sessions · 8 points
Session 1Avoided-Cost and Return-on-Investment Methods
- Estimate the expected frequency and severity of incidents a proposed control would prevent, based on historical or comparable data.
- Calculate the avoided cost of a proposed control by multiplying expected prevented incidents by the calibrated cost-per-incident figure.
- Calculate return on investment and payback period for the proposed control, using consistent assumptions the finance team will recognise.
- Compare multiple control options on a like-for-like return basis to recommend the option with the strongest risk-adjusted return.
Session 2Handling Uncertainty and Probability in the Model
- Apply a range or probability distribution to incident frequency estimates rather than presenting a single unsupported number.
- Run a sensitivity analysis showing how the business case outcome changes under conservative, expected and optimistic assumptions.
- Explain the confidence level behind key assumptions honestly, distinguishing well-evidenced figures from reasoned estimates.
- Present a probability-weighted expected return alongside the best and worst case to avoid overstating certainty to decision-makers.
03Structuring the Business Case
2 sessions · 8 points
Session 1Framing the Case in Financial and Operational Language
- Frame the safety investment case using the same terminology, such as payback period or net present value, used for other capital requests.
- Connect the proposed investment to operational priorities such as production continuity, quality or workforce retention, not compliance alone.
- Avoid framing the case solely around regulatory risk, since decision-makers often discount enforcement probability against a defined financial return.
- Tailor the level of technical safety detail to the audience, keeping the core financial argument prominent and easy to follow.
Session 2Structuring Assumptions, Options and Recommendations
- Structure the business case with a clear problem statement, options considered, assumptions, financial analysis and a specific recommendation.
- Present at least one do-nothing or minimal-cost option so decision-makers can see the cost of inaction alongside the proposed investment.
- Document all assumptions in an appendix so reviewers can challenge or adjust individual inputs without rejecting the whole case.
- Align the recommended option with the organisation's existing risk appetite and capital approval thresholds to speed up sign-off.
04Presenting, Approving and Tracking the Investment
2 sessions · 8 points
Session 1Presenting the Case to a Budget-Holding Audience
- Prepare a concise presentation leading with the financial return before the technical safety rationale, matching how other investment cases are pitched.
- Anticipate financial and operational questions about payback period, ongoing costs and implementation risk before the meeting.
- Use visual comparisons of cost of inaction versus cost of investment to make the trade-off immediately clear to the audience.
- Practise responding to scepticism about incident probability estimates without becoming defensive or overstating certainty.
Session 2Tracking Realised Savings After Implementation
- Track actual incident rates and costs after implementation against the business case's projected avoided costs.
- Report realised return on investment to the approving audience to build credibility for future safety investment proposals.
- Adjust the underlying cost model using real post-implementation data to improve the accuracy of future business cases.
- Use a successfully tracked business case as a reference example when proposing further safety investment initiatives.
