Learning Outcomes
After reading this article, you will be able to explain the principles and techniques of variance analysis, identify typical causes of variances, interpret their significance, and comment on their implications for performance and strategy. You will gain the ability to produce clear management reports that explain variances and provide relevant recommendations for action, aligned with organisational objectives and ACCA APM exam scenarios.
ACCA Advanced Performance Management (APM) Syllabus
For ACCA Advanced Performance Management (APM), you are required to understand not only how to calculate variances but also to interpret, explain, and report them in a way that addresses organisational performance and strategy. In particular, this article addresses:
- The calculation and interpretation of key variances in management control reports
- Explaining the causes of significant variances and their impact on objectives
- Identifying and evaluating the strategic implications of performance trends or anomalies
- Communicating findings clearly to management with actionable recommendations
- Aligning performance commentary with the strategic objectives of the business
Test Your Knowledge
Attempt these questions before reading this article. If you find some difficult or cannot remember the answers, remember to look more closely at that area during your revision.
-
Which type of variance shows the difference between expected and actual performance caused by events outside managers’ control?
- Operational variance
- Planning variance
- Efficiency variance
- Price variance
-
True or false? All adverse variances represent poor performance and indicate that corrective action is needed.
-
Explain why simply reporting the amount of a variance is not enough in strategic management reporting.

A company notes a favourable material usage variance but an adverse sales volume variance. What strategic issue should be considered when explaining these results?
Introduction
Variance analysis is a fundamental management control tool. However, in ACCA APM, it is not enough to calculate variances—you must interpret them, determine causes, and communicate implications through effective management reporting. This article explains how to analyse, explain, and comment on key variances, and how to link them to strategy and organisational objectives.
Reporting on performance means not just reporting numbers, but providing commentary that helps management understand why results occurred, whether they signal good or poor performance, and what should be done next. Clear explanations contribute to improved decision-making and support strategic goals.
Key Term: variance analysis
The process of comparing actual results to budgeted or standard expectations, calculating differences (variances), and investigating causes.
THE ROLE OF VARIANCE ANALYSIS IN MANAGEMENT REPORTING
Variance analysis measures the difference between actual and expected results. This allows management to focus attention on areas requiring action (“management by exception”). But in APM, you are expected to go further: explain not only the size but also the meaning and cause of variances, and what they imply for strategy.
Types of Variances
Key Term: planning variance
A variance arising from inaccurate budgets or standards, usually due to changes in external factors or poor forecasting.Key Term: operational variance
A variance arising from the day-to-day actions or decisions of managers—i.e., what is controllable during the period.
Basic and Advanced Variances
Common variances include:
- Material price and usage variances
- Labour rate and efficiency variances
- Sales price and volume variances
- Overhead expenditure and volume variances
At a more strategic level, advanced variances such as planning and operational variances, sales mix and quantity, and market size and share provide deeper analysis of performance.
EXPLAINING VARIANCES IN CONTEXT
Calculation is the starting point, but effective management reporting requires explaining:
- What the variance represents
- What caused it (internal or external factors)
- Whether it is within the manager’s control
- The potential impact on strategy or targets
Reporting should distinguish between variances caused by:
- Factors outside management control (e.g., sudden inflation, regulatory changes)
- Factors within management control (e.g., inefficiency, waste)
Explanation should also prioritise material and significant variances that affect strategic objectives.
Worked Example 1.1
Scenario:
MagicBake Ltd budgeted to sell 10,000 cakes at $2.00 per unit. Actual sales were 8,200 cakes at $2.15 per unit.
Calculate and explain the sales volume and sales price variances, highlighting their strategic implications.
Answer:
Sales volume variance: (8,200 – 10,000) × budget price $2.00 = $3,600 adverse.
Sales price variance: (actual $2.15 – budget $2.00) × 8,200 = $1,230 favourable.
While the company achieved a higher sales price (possibly reflecting improved brand or market changes), the adverse sales volume variance indicates lower demand than budgeted. This could signal a loss of market share or fundamental issues with product appeal. The strategic implication is that simply raising prices may not align with sales growth objectives. Commentary should recommend market analysis and review of competitive positioning.
STRATEGIC IMPLICATIONS OF VARIANCES
Explaining variances adds value only when linked to broader strategy.
Unfavourable variances do not automatically indicate failure and may be part of a deliberate strategic choice (for example, increased costs due to investment in quality). Favourable variances can sometimes be a warning sign, such as cost savings reducing product quality or capacity for growth.
Management reporting commentary must link performance to company mission, key success factors, and long-term goals. For example, a short-term saving on training that leads to higher staff turnover could conflict with an objective of building a skilled workforce.
Common Causes and Strategic Impact
- External factors: Recession, market trends, exchange rates (planning variances)
- Internal efficiency: Productivity changes, wastage, process improvement (operational variances)
- Resource allocation: Investment in R&D, marketing, or technology
- Control breakdowns: Poor supervision, errors, or structural issues
Worked Example 1.2
Scenario:
EcoFit, a sportswear manufacturer, reports a favourable material price variance but an adverse material usage variance.
Draft a brief management report comment explaining these results and their strategic implications.
Answer:
The favourable price variance suggests materials were bought at a lower cost than standard, perhaps due to new suppliers. However, the adverse usage variance means more material was consumed than expected. There may be a quality issue with cheaper inputs leading to inefficiency or waste. Strategically, focusing on cost at the expense of quality could damage EcoFit's commitment to sustainability and product integrity. Management should investigate supplier quality and consider the long-term impact on reputation.
Exam Warning
In APM exams, avoid generic explanations for variances (e.g., "costs were higher than budgeted"). Always identify likely causes and discuss the relevance to the organisation’s strategy and objectives. Assess controllability and the impact of management actions.
MANAGEMENT COMMENTARY – BEST PRACTICE
Effective management reporting commentary should:
- Focus on significant variances that affect key objectives
- Clearly explain the likely cause and controllability
- Link the variance to strategic goals and risks
- Recommend practical actions or monitoring where needed
- Present information concisely and in an accessible format—often with summary tables and bullet points
Key Term: management commentary
The written explanation accompanying a performance report, analysing results, causes of variances, and their implications for decision-making and future plans.
AVOIDING COMMON REPORTING MISTAKES
Typical errors in management commentary include:
- Reporting numbers only, with no explanation
- Blaming adverse variances entirely on external factors without evidence
- Focusing solely on favourable variances and ignoring warning signs
- Failing to recommend corrective or follow-up actions
Revision Tip
Report commentary should highlight the "story behind the numbers", connect performance to strategic priorities, and recommend clear next steps.
Summary
Variance analysis must actively support strategic management by explaining both the causes and consequences of performance differences. Management reporting should clarify whether variances are due to controllable or uncontrollable factors, assess their significance, and provide direction to support strategy and continuous improvement.
