Run a fraud risk assessment for a business process

Help me run a fraud risk assessment for a business process. Process: [e.g. procurement, payroll, expenses, revenue recognition, inventory, customer refunds] How it works: [KEY steps, roles, systems, approval limits] Existing controls: [LIST] Pressures and incentives: [e.g. aggressive targets, bonus structures, cost cuts, staff turnover] Past incidents or allegations: [SUMMARY or "none known"] Work through: 1. Fraud schemes - 8-12 realistic schemes for this process across asset misappropriation, corruption, and financial reporting fraud. For each: who could commit it (role), how, and how they would conceal it. Include collusion and management override scenarios. 2. Fraud triangle - for the main schemes, the likely pressure, opportunity, and rationalization. 3. Assessment table - columns: Scheme, Perpetrator role, Likelihood, Impact, Existing controls, Would controls prevent or detect it?, Residual risk. 4. Control gaps - especially segregation of duties, master data changes, manual overrides, and controls performed by the same person they are meant to check. 5. Recommendations - preventive and detective controls, including data analytics tests to run on the full population. 6. Red flags for managers and staff in this process. Keep it practical, and do not accuse anyone: this assesses where fraud could happen, not who did it. If I describe a suspected live fraud, tell me to preserve evidence and involve legal before investigating.
