PM: Budgeting and control

Answer: C. Budgets sit at the interface of strategic and operational management — they convert long-term strategic objectives (e.g. grow market share by 15%) into short-term quantified targets (e.g. achieve sales of £X in Q1) that can be monitored and managed. They cascade from the strategic level (board objectives) through tactical (divisional plans) to operational (departmental targets). They do not replace strategic planning (A) — they implement it. Modern budgeting includes non-financial measures (B is wrong). They connect strategy to operations across all levels (D is wrong).

Answer: D. ZBB requires every activity and expenditure to be justified from zero rather than using prior year as a baseline. Benefit: it challenges all spending and removes historical inefficiencies that incremental budgeting perpetuates (the 'spend it or lose it' problem). Problem: it is extremely resource-intensive — every manager must justify every pound of expenditure, which is time-consuming and may be resisted. Option A incorrectly states ZBB is faster (incremental is faster). Option B describes incremental budgeting's characteristics. Option C is a mischaracterisation — ZBB forces a forward-looking justification, not reliance on historical data.

Answer: A. Beyond budgeting (Hope and Fraser) argues that fixed annual budgets create gaming, rigidity, and bureaucracy. The model replaces them with: relative performance targets (beat competitors, not a fixed budget), rolling forecasts (continuous forward-looking planning rather than annual), and decentralised decision-making (front-line managers empowered to respond to market conditions). Option B is a caricature — beyond budgeting still requires financial management, just not fixed annual targets. Option C describes process automation, not beyond budgeting principles. Option D confuses beyond budgeting with ZBB — they are different critiques of traditional budgeting.

Answer: B. The examiner (SD25, Example 2) illustrated this exact calculation using the tabular method. Cumulative average for 1 batch = 1,500 hrs. Cumulative average for 2 batches = (1,500+1,350)÷2 = 1,425 hrs. Learning rate = 1,425÷1,500 = 0.95 = 95%. When cumulative output doubles from 2 to 4 batches, the cumulative average falls by the learning rate again: 1,425 × 0.95 = 1,353.75 hrs per batch, which is option B. Option A uses a 90% rate (1,500 × 0.81 = 1,215). Option C also uses a 90% rate but with an incorrect average. Option D uses an 85% rate. The key examiner point: when batches double (1→2, 2→4), apply the learning rate to the cumulative average — not to individual batch time.

Answer: C. The learning curve effect applies during a period of increasing familiarity with a new process or product. As workers become more experienced, cumulative average time per unit falls. However, this effect is not infinite — eventually workers reach a 'steady state' (plateau) where no further efficiency gains are achievable. At this point, standard cost accounting resumes and the learning curve effect is no longer relevant to cost estimations. The timing is determined by the nature of the task, not calendar time (A), output level relative to breakeven (B), or capacity utilisation (D).

Answer: D. The mix variance compares the actual quantities used with the quantities that the same total input would have contained in standard proportions, valued at standard prices. Total actual input = 3,000kg. In standard mix: A = 60% × 3,000 = 1,800kg; B = 40% × 3,000 = 1,200kg. Valuing the differences (standard-mix quantity − actual quantity) at standard price: A = (1,800 − 1,680) × £4 = £480 favourable (120kg less of the cheaper material used); B = (1,200 − 1,320) × £6 = £720 adverse (120kg more of the dearer material used). Net mix variance = £480 F − £720 A = £240 adverse. The mix is adverse because the actual input substituted expensive Material B for cheaper Material A. Option A reverses the sign. Options B and C take only one material's effect (£120 net per material is not the method). The mix variance is always valued at standard, not actual, prices.

Answer: A. The sales mix variance measures the effect of selling products in a different proportion from budget, valued at the standard contribution per unit. Apply the budgeted mix (60% K : 40% L) to the actual total volume of 1,100 units: K should be 1,100 × 60% = 660; L should be 1,100 × 40% = 440. Compare with actual sales, valued at each product's standard contribution. K: (500 − 660) × £30 = £4,800 adverse (fewer of the higher-contribution product sold). L: (600 − 440) × £20 = £3,200 favourable (more of the lower-contribution product sold). Net sales mix variance = £4,800 A − £3,200 F = £1,600 adverse. The mix shifted towards the lower-margin Product L, which is adverse overall. Option B reverses the sign. Options C and D each show only one product's component instead of the net figure.

Answer: B. Planning variance = (Original standard − Revised standard) × Actual quantity = (£8 − £10) × 2,000 = −£2 × 2,000 = −£4,000 adverse. This reflects the uncontrollable external price increase. Operational variance = (Revised standard − Actual price) × Actual quantity = (£10 − £10.50) × 2,000 = −£0.50 × 2,000 = −£1,000 adverse. This reflects the purchasing manager's performance against the updated benchmark — they paid £0.50/kg more than the revised standard. Total price variance = −£4,000 − £1,000 = −£5,000 adverse = (£8−£10.50)×2,000 ✓. Option B is correct. Option A reverses the two amounts. Option C makes the planning variance favourable, but a price rise above the original standard is adverse. Option D makes the operational variance favourable, but paying above the revised standard is adverse.

Answer: C. Planning variances separate uncontrollable external factors (revisions to the standard) from controllable operational performance. If the learning rate turned out to be 85% instead of 90%, the difference between what was planned (90% curve) and what was achievable (85% curve) is a planning variance — it reflects forecasting error, not management failure or success. The operational variance then compares actual performance to the revised (85%) standard — this is what management is assessed on. Option A ignores the planning/operational split that removes uncontrollable items. Option B incorrectly assumes all learning improvements are operational. Option D applies incorrect reasoning — a favourable planning revision (better learning) produces a favourable planning variance.

Answer: D. This is a classic dysfunctional behaviour example: the manager optimises one metric (favourable price variance) in a way that damages the broader system. JIT aims to eliminate inventory waste — materials arrive just in time for production. Bulk buying creates inventory, which JIT explicitly seeks to avoid: it ties up working capital, creates storage costs, increases the risk of damage or obsolescence, and undermines the responsiveness JIT enables. Standard costing that rewards bulk purchasing is misaligned with JIT objectives. Options A and B ignore this misalignment. Option C is factually incorrect.

Answer: A. ABB uses cost drivers (identified through ABC analysis) to build budgets: instead of simply budgeting £X for 'overhead,' it budgets for the activities that cause overhead and the volume of those activities. This creates a much clearer link between what the organisation does (activities) and what it costs, enabling targeted management of cost drivers. ABB uses forward-looking activity driver volumes, not prior year data (B) — that's incremental budgeting. ABB identifies costs by activity but does not automatically eliminate non-value-adding ones (C) — that requires separate management decision. ABB and ZBB are distinct concepts (D): ZBB justifies all expenditure from zero; ABB links costs to cost drivers.

Answer: B. Behavioural research on budgeting (Stedry, Hopwood) consistently finds that motivation is maximised by targets that are challenging but achievable — they require genuine effort but are perceived as attainable. Easily achievable targets (A) lead to complacency and underperformance — managers hit the target and stop. Ideal/perfection standards (C) are consistently unachievable and demoralise employees over time. Impossible targets (D) are simply ignored — once employees believe a target cannot be achieved, it loses motivational power entirely. The examiner specifically notes this as a budgetary behaviour area candidates should understand.

Answer: C. The material usage variance measures the total difference between standard and actual material usage. This can be further analysed: the mix variance measures the effect of changing the proportions of materials used (holding total input constant), while the yield variance measures the effect of producing more or less output than expected from the actual input. Together: Mix variance + Yield variance = Usage variance. This subdivision is only meaningful when multiple materials are combined in a process where the proportions can vary. Options A and B reverse the relationship. Option D is incorrect — they are not independent.

Answer: D. Forecast: Y = 15,000 + 120(500) = 15,000 + 60,000 = £75,000. R² (coefficient of determination) = 0.88 means 88% of the variation in cost (Y) is explained by changes in production volume (X). The remaining 12% of variation is explained by other factors not included in the model. R² is not the correlation coefficient (A) — the correlation coefficient (r) = √0.88 = 0.938. R² does not mean 88% of costs are variable (B) — the variable:fixed split is determined by the regression equation (£120/unit variable, £15,000 fixed). R² does not indicate forecast accuracy range (C) — that requires confidence intervals.

Answer: A. Budgetary slack is the deliberate manipulation of budget submissions — understating revenues or overstating costs — to create a comfortable buffer that makes targets easy to achieve and look good at year-end. This is a specific risk of participative budgeting because operational managers have private information and the latitude to set their own targets. Participative budgeting is slower than top-down (B is wrong) — coordinating bottom-up submissions takes time. Option C is a benefit, not a disadvantage. Option D is an unsupported generalisation — total budget expenditure depends on many factors.

Answer: C. Market size variance = (Actual market − Budgeted market) × Budgeted market share % × Standard contribution = (80,000 − 100,000) × 10% × £15 = −2,000 × £15 = £30,000 adverse. Market share variance = (Actual sales − Actual market × Budgeted share) × Standard contribution = (8,800 − 80,000×10%) × £15 = (8,800 − 8,000) × £15 = 800 × £15 = £12,000 favourable. The company sold fewer units than budgeted because the market shrank (size variance adverse) but captured a greater share of that smaller market than planned — 11% actual vs 10% budgeted (share variance favourable). Option A has wrong share variance. Option B has wrong share figure. Option D has wrong signs.

Answer: C. Standard costing provides pre-determined expected costs (standards) that serve as benchmarks. Comparing actual costs to standard costs produces variances, enabling management by exception — managers focus attention on significant deviations rather than reviewing every line of cost. This is the fundamental purpose. Standard costing does not guarantee profitability (A) — prices and volumes determine that. It complements, not replaces, actual cost recording (B). Standard costs may be used for inventory valuation in management accounts but this is not an IFRS requirement (D) — IFRS requires actual or current cost for statutory reporting.

Answer: D. This is a textbook dysfunctional behaviour example: the manager maximises a measured metric (labour efficiency) in a way that undermines overall organisational objectives (quality). The root cause is the performance measurement system — by measuring only efficiency and not quality, it creates an incentive to trade quality for speed. A balanced measurement system would include quality measures (defect rates, rework costs) alongside efficiency to prevent this trade-off. The manager's behaviour is not excellent (A) — it achieves one target while damaging another. Total cost may not capture quality costs (B). Option C deflects from the behavioural issue.

Answer: A. The syllabus (D1j, revised this version to specifically include 'volatility') asks how budgetary systems can deal with uncertainty and volatility. Rolling budgets are updated continuously — as each period ends, a new period is added, keeping the planning horizon constant and always current. This adaptability makes rolling budgets well-suited to volatile environments. Fixed annual budgets (B) become outdated quickly in volatile conditions. ZBB (C) addresses inefficient spending, not volatility. Incremental budgeting (D) is the least adaptive — it simply adds a percentage to the prior period regardless of changed conditions.

Answer: B. 80% learning curve: each time cumulative output doubles, cumulative average time per unit falls to 80% of the previous average. Cumulative average: 1 unit = 400 hours. 2 units = 400×0.8 = 320 hours average. 4 units = 320×0.8 = 256 hours average. Total time for 4 units = 4×256 = 1,024 hours. Option A: 4×320 = 1,280 (uses 2-unit average for 4 units). Option C: 2×400 = 800 (applies 80% only once to total). Option D: uses wrong starting point. The 80% curve applied twice (as output doubles from 1→2→4): 400 × 0.8 × 0.8 × 4 = 400 × 0.64 × 4 = 1,024 ✓.

Answer: C. The controllability principle states that managers should only be held responsible for items within their control. Allocating uncontrollable head office costs to a divisional manager's performance report is demotivating (they cannot improve them), distorts performance assessment, and reduces the usefulness of the report as a control tool. The solution is to prepare two versions: a controllable profit statement (for performance assessment) and a net profit statement (including allocations, for information only). Options A, B and D describe financial reporting principles unrelated to the controllability concept in performance management.

Answer: D. Persistent adverse variances signal a systematic problem that warrants investigation. Root causes of an adverse material usage variance: standards set incorrectly (too tight), quality of materials received has deteriorated (buy cheaper = more waste), production process inefficiency, machine malfunction increasing waste, or different product mix. Investigation enables targeted corrective action. Relaxing the standard (A) removes the signal — the problem remains but is hidden. Immediate dismissal (B) is a disproportionate response before investigation. Ignoring persistent variances (C) allows problems to compound and signals to management that the system is not taken seriously.

Answer: C. Deliberately overstating forecasts to gain resource advantages is dishonest — it misrepresents reality, manipulates the allocation process, and violates the ethical principle of integrity. The subsequent attribution of failure to 'market conditions' compounds the dishonesty. This behaviour is not legitimate budgetary slack (A) — slack may arise from genuine uncertainty, but this is intentional misrepresentation. It is misalignment with organisational interests, not goal congruence (B). Creative accounting (D) applies to financial reporting, and even there it is not 'acceptable' when it involves misrepresentation.

Answer: B. Sales quantity variance = (Actual total sales − Budgeted total sales) × Weighted average standard contribution = (900 − 1,000) × £30 = −100 × £30 = −£3,000 adverse. The total market volume was lower than budgeted by 100 units, reducing contribution by £3,000. The sales mix variance then separately explains the effect of selling proportionally different amounts of P and Q from the standard mix. Quantity and mix variances together equal the total sales volume variance. Check: Sales volume variance = (Actual sales − Budgeted) × individual contributions: P:(400−500)×£40=−£4,000; Q:(500−500)×£20=£0. Total=−£4,000. Mix: P:(400−450)×£40=−£2,000 adv; Q:(500−450)×£20=+£1,000 fav. Mix=−£1,000. Quantity=Mix+Qty: −£4,000=−£1,000+Qty → Qty=−£3,000 ✓. £6,000 values the 100-unit shortfall at £60 (the two contributions added together), and £1,500 values it at £15.

Answer: B. The learning curve model has important limitations: it assumes repetitive production (does not apply to non-repetitive or creative tasks), assumes consistent improvement (does not account for disruptions, staff turnover, or technology changes), reaches a steady state beyond which no further improvement occurs, and may overestimate improvements in practice. The examiner expects students to discuss these reservations critically, not just calculate learning curve outputs. Option A is the opposite of the truth. Option C is wrong — the curve applies across cumulative batch production. Option D is an unsupported numerical threshold.

Answer: C. Inter-variance relationships are a key skill. The adverse material price (cheaper materials) combined with favourable usage (less used) but adverse labour efficiency (more time taken) suggests a possible chain: purchasing bought cheaper but lower quality materials → workers used less material (perhaps higher yield) but found the materials harder to work with → labour took longer. Alternatively, better quality control reduced material waste but took more time. These linkages should be investigated together. Simply adding variances (B) loses the insight. Not all variances need equal investigation (A) — magnitude and persistence guide priorities. Variances can be deeply interconnected (D is wrong).

Answer: C. The syllabus specifically includes 'wider issues involved in changing material mix' (D4b): cost savings from cheaper ingredients must be weighed against quality impact (customers may notice taste changes), yield effects (cheaper ingredients may increase waste or reduce output), brand damage (reputation built on quality could be undermined), and regulatory compliance (food labelling must accurately reflect ingredients). A favourable mix variance in isolation does not tell the full story. Pure financial analysis (B) ignores these critical non-financial factors. Reversing all deviations (D) would eliminate both harmful and beneficial changes. Option C is comprehensive and correct.

Answer: B. The primary advantage of rolling budgets is the maintenance of a constant planning horizon — as each period ends, a new period is added, keeping the forward-looking view relevant. In annual budgets, by November the remaining 2-month budget is a poor planning tool; rolling budgets maintain full planning relevance throughout. They are more expensive (A), not cheaper — more frequent updates require more management time. They still support variance analysis (C) — actual vs the rolling budget. They improve forecast accuracy through more recent data but cannot guarantee accuracy (D) — uncertainty is inherent.

Answer: B. Planning variances are intended to isolate genuinely uncontrollable external changes from controllable operational factors. A legitimate reason to revise a standard (and thus create a planning variance rather than an operational one) is an external event that was unforeseeable and outside management's control — such as a global commodity price shock. Poor management planning (A), quality failures (C), and internal spending decisions (D) are all within management's control and should remain as operational variances — they reflect performance, not external change. Allowing controllable factors into planning variances would distort accountability.

Answer: B. Implementing ABB requires: identifying all significant activities, determining cost drivers for each, establishing driver rates, and training managers in the new approach. In complex organisations with many activities, this is a substantial investment of time and resource. There may also be resistance from managers comfortable with the existing system, IT system constraints, and difficulties in identifying reliable cost driver data. ABB is not prohibited in the public sector (A) — it is actually encouraged as it links spending to activities and outcomes. 'Always resist' (C) is an overstatement. Incremental budgeting has significant weaknesses (D) — the question acknowledges change is intended.

Answer: A. TQM's philosophy is continuous improvement (kaizen) and the elimination of waste and defects — moving toward perfection. Standard costing sets a fixed efficiency target based on 'normal' conditions, which may include allowances for waste, idle time, or sub-optimal performance. This 'acceptable' standard conflicts with TQM's aim to continuously push performance beyond any fixed standard. Additionally, variance analysis reports are typically monthly — too infrequent for TQM's real-time process control requirements. The examiner includes 'dysfunctional variances in JIT and TQM environments' as a specific syllabus point (D7e). Options B, C, and D are factually incorrect.
