Discipline Section - Analysis, Controls, and Planning
The disciplines reward transfer, not memorization
The Discipline section tests whether you can apply a smaller body of rules to unfamiliar fact patterns. Business Analysis and Reporting leans on ratio analysis, variance analysis, cost accounting, forecasting, valuation, derivatives and hedging, and segment/discontinued-operations reporting. Information Systems and Controls leans on IT general controls, change management, segregation of duties, SOC reporting, and data integrity. Tax Compliance and Planning leans on entity choice, property transactions, and multi-year planning.
Ratios and variances carry the most points
Know the families: liquidity (current, quick), solvency (debt-to-equity, times interest earned), activity (inventory turnover, days sales outstanding), and profitability (gross margin, return on assets, DuPont decomposition). In variance analysis, a price/rate variance isolates the difference between actual and standard price at actual quantity; a quantity/efficiency variance isolates the difference between actual and standard quantity at standard price. A favorable variance is not automatically a good outcome - buying inferior material at a lower price can create an unfavorable usage variance.
Controls and valuation
IT general controls (access, change management, operations) support the application controls that produce reliable data. For valuation, the income approach discounts projected cash flows; sensitivity analysis tests how conclusions move with key assumptions. Discontinued operations are reported net of tax below income from continuing operations, and only when the disposal represents a strategic shift.
Traps: mixing the price and quantity variance formulas; forgetting that a ratio's direction depends on whether the item is an asset, liability, revenue, or expense; treating every favorable variance as desirable.
Rule of thumb: decompose before you conclude - write the variance as (actual − standard) × the base, and label the base explicitly.
Worked example: Standard 3 lbs at $4/lb; actual 3,200 lbs at $3.90/lb for 1,000 units. Price variance = ($3.90 − $4.00) × 3,200 = $320 favorable. Quantity variance = (3,200 − 3,000) × $4.00 = $800 unfavorable.
