Welcome to Performance Analysis!
Hello there! Welcome to one of the most important chapters in your PM journey. If you’ve ever looked at your bank account at the end of the month and wondered, "Where did all my money go? I planned to save $200!", then you are already doing performance analysis. In this chapter, we take that simple idea and apply it to a business setting.
In the context of Budgeting and Control, performance analysis is about being a detective. We compare what we planned (the budget) to what actually happened (actual results). Our goal isn't just to find the differences, but to understand why they happened so we can make better decisions in the future. Don't worry if the formulas look a bit scary at first—we'll break them down step-by-step!
1. The Basics: Standard Costing and Variances
Before we can analyze performance, we need a benchmark. This is called Standard Costing. Think of a "Standard" as a "Target" for a single unit of product.
Key Term: Variance
A variance is simply the difference between the standard (what should have happened) and the actual (what did happen).
• Favorable (F): This happens when actual results are better for profit than expected (e.g., spending less on materials).
• Adverse (A): This happens when actual results are worse for profit than expected (e.g., paying employees a higher rate than planned).
The "P-U" and "R-E" Memory Aid
To keep things simple, remember these pairs:
• For Materials, we look at Price and Usage (P-U).
• For Labor, we look at Rate and Efficiency (R-E).
Material Variances
1. Material Price Variance: Did we pay more or less per kg than planned?
\( \text{Price Variance} = (\text{Standard Price} - \text{Actual Price}) \times \text{Actual Quantity purchased} \)
2. Material Usage Variance: Did we use more or less material than we should have for the actual production?
\( \text{Usage Variance} = (\text{Standard Quantity for actual production} - \text{Actual Quantity used}) \times \text{Standard Price} \)
Labor Variances
1. Labor Rate Variance: Did we pay our workers more or less per hour than planned?
\( \text{Rate Variance} = (\text{Standard Rate} - \text{Actual Rate}) \times \text{Actual Hours worked} \)
2. Labor Efficiency Variance: Did our workers take more or less time than expected to make the products?
\( \text{Efficiency Variance} = (\text{Standard Hours for actual production} - \text{Actual Hours worked}) \times \text{Standard Rate} \)
Quick Review: Always use the Standard Price when calculating the Usage or Efficiency variance. This ensures we are only looking at the "volume" of resources used, not the price changes!
2. Sales Variances
When analyzing sales, we want to know if our profit changed because we changed our prices or because we sold a different amount of items.
Sales Price Variance:
\( (\text{Actual Selling Price} - \text{Standard Selling Price}) \times \text{Actual Quantity sold} \)
Sales Volume Profit Variance:
\( (\text{Actual Quantity sold} - \text{Budgeted Quantity sold}) \times \text{Standard Profit per unit} \)
Note: If the company uses Marginal Costing, use Standard Contribution instead of Standard Profit!
3. Planning and Operational Variances
This is where PM gets interesting! Sometimes, a manager is blamed for a "Bad" (Adverse) variance that wasn't their fault. For example, what if the price of raw materials doubled globally due to a war? Is it the purchasing manager's fault? No.
To be fair, we split variances into two parts:
1. Planning Variances: These compare the Original Budget to a Revised (Realistic) Budget. These are caused by things outside of the manager's control (like market changes).
2. Operational Variances: These compare the Actual Results to the Revised Budget. These are the things the manager can control.
Step-by-Step for Planning & Operational:
Step 1: Identify the Original Standard (what we thought at the start).
Step 2: Identify the Revised Standard (what we know now).
Step 3: Identify the Actual results.
Step 4: Planning Variance = (Original Standard - Revised Standard) x Actual Volume.
Step 5: Operational Variance = (Revised Standard - Actual Result) x Actual Volume.
Real-World Analogy: Imagine you planned to drive to a friend's house in 30 minutes (Original Budget). However, there was a massive unexpected flood on the main road, making the fastest possible time 50 minutes (Revised Budget). If you arrived in 55 minutes:
• Planning Variance: 20 minutes (The flood - not your fault).
• Operational Variance: 5 minutes (You were a little slow driving - your fault!).
Key Takeaway: Splitting variances makes the performance appraisal process much fairer and more useful for future planning.
4. Fixed Overhead Variances
Fixed overheads are tricky because they don't change with production levels. However, in Absorption Costing, we "pretend" they do by using an Overhead Absorption Rate (OAR).
Fixed Overhead Expenditure Variance:
\( \text{Budgeted Expenditure} - \text{Actual Expenditure} \)
(Simple: Did we spend more cash on rent/salaries than we thought?)
Fixed Overhead Volume Variance:
\( (\text{Actual Units} - \text{Budgeted Units}) \times \text{Standard OAR per unit} \)
(This measures if we produced more or less than we planned, which affects how much overhead is "absorbed" into products.)
5. Behavioral Aspects of Control
Performance analysis isn't just about the numbers; it's about the people. How do budgets and variances affect how employees behave?
Common Pitfalls to Avoid:
• Budgetary Slack: Managers might make their targets too easy so they always get a "Favorable" variance. This is like setting your alarm for 6:00 AM when you know you only need to wake up at 8:00 AM!
• Short-termism: A manager might stop maintaining machinery to save money today (creating a favorable expenditure variance), but the machine might break down next month.
• Demotivation: If targets are impossible to reach, staff will stop trying. If variances are used purely to punish people, staff will hide information.
Did you know? High-performing companies often use "Beyond Budgeting" techniques where they focus on relative targets (being better than competitors) rather than fixed internal budget numbers.
Summary Checklist
Before moving to the next chapter, make sure you can:
• Calculate basic material, labor, and sales variances.
• Explain the difference between a Planning and an Operational variance.
• Discuss why a "Favorable" variance might actually be bad (e.g., buying cheap, poor-quality materials leads to high waste).
• Identify the behavioral impact of using variances for performance measurement.
Final Tip: When you see a variance in an exam question, always ask yourself: "Is this controllable by the manager?" This is the heart of performance analysis in the ACCA PM syllabus!
