Business Skills and Knowledge
What the domain really tests
Business items test whether you can read financials, allocate capital, and manage operations with data. Concepts: financial statements (balance sheet, income statement, statement of cash flows), ratio analysis (operating margin, days in accounts receivable, current ratio, debt-to-capitalization), budgeting (operating, capital, variance analysis), cost accounting and contribution margin, break-even analysis, revenue cycle and payer contracting, capital budgeting (NPV, IRR, payback), working capital, supply chain and staffing productivity (FTEs per adjusted occupied bed, worked hours per patient day), quality and process improvement, marketing and strategy (SWOT, five forces, portfolio analysis), and risk management and compliance.
Traps that recur
- Confusing profit with cash. Positive margin with ballooning receivables can still starve cash; watch days in A/R and the cash flow statement.
- Ignoring contribution margin. A service line can look unprofitable fully loaded but contribute positively to fixed costs; dropping it may reduce total margin.
- Wrong capital metric. NPV and IRR are preferred for long-term decisions; payback ignores time value and is a screening tool only.
- Sunk costs. Money already spent should not drive a go/no-go decision.
- Variance without volume adjustment. A budget overrun may be purely volume-driven; flex the budget before blaming cost control.
Worked rule of thumb
The break-even formula: break-even volume = fixed costs ÷ (price − variable cost per unit). If a new clinic has $600,000 fixed costs, $150 per visit revenue, and $50 variable cost, contribution is $100, so break-even is 6,000 visits.
Example
A service line shows a $200,000 loss fully loaded but a $300,000 positive contribution margin. The defensible recommendation is to retain and optimize it while attacking fixed-cost allocation - not to close it, which would drop contribution and worsen the bottom line.
