Budgetary systems and types of budget

Welcome to Budgetary Systems!

Hi there! Welcome to one of the most practical parts of your Performance Management (PM) studies. If you have ever tried to save money for a new phone or planned the expenses for a trip, you have already done "budgeting." In a business, budgets are the roadmap that tells the company where it is going and how it plans to get there. Don't worry if this seems a bit dry at first—we are going to break it down into simple, logical pieces that make sense in the real world.

1. Why do we even bother with Budgets?

Before we look at the "how," we need to understand the "why." A common mistake is thinking budgets are only about limiting spending. They are actually much more! A great way to remember the purposes of budgeting is the mnemonic CRUMPET.

• C – Coordination: Ensuring all departments (like Sales and Production) are working toward the same goal.
• R – Responsibility: Giving managers a "bucket" of money or a target so they know what they are accountable for.
• U – Utilization: Making sure resources (like staff or machines) are used efficiently.
• M – Motivation: Giving staff a target to aim for (if the target is realistic!).
• P – Planning: Forcing managers to look ahead rather than just reacting to daily problems.
• E – Evaluation: Comparing what actually happened to what we planned to see how well we did.
• T – Telling (Communication): Letting everyone in the organization know what the plan is.

Quick Review: Budgets aren't just handcuffs for spending; they are tools for communication and planning!

2. Fixed vs. Flexible Budgets

This is a "must-know" topic for your exam. Understanding the difference between these two is the key to passing variance analysis later on.

Fixed Budgets

A Fixed Budget is a budget created for a single, specific level of activity (e.g., a budget based on selling exactly 10,000 units).
The Problem: If you actually sell 12,000 units, comparing your actual costs to a 10,000-unit budget is like comparing apples to oranges. Of course you spent more on materials—you made more products!

Flexible Budgets

A Flexible Budget is a budget that recognizes different cost behaviors. It is designed to change as the volume of activity changes.
Did you know? To "flex" a budget, you must keep Fixed Costs the same as the original budget but change Variable Costs to match the actual number of units sold/produced.

The Golden Formula for Flexing:
\( \text{Flexed Variable Cost} = \left( \frac{\text{Budgeted Variable Cost}}{\text{Budgeted Units}} \right) \times \text{Actual Units} \)

Example: If you budgeted \$5,000 for materials to make 1,000 chairs, but you actually made 1,200 chairs, your "flexed" budget would be:
\n\( (\$5,000 / 1,000) \times 1,200 = \$6,000 \)

Key Takeaway: Always compare Actual Results to a Flexed Budget to see how well you actually controlled costs.

3. Types of Budgetary Systems

Different businesses use different methods to build their budgets. Let’s look at the main four required for your syllabus.

A. Incremental Budgeting

This is the "traditional" way. You take last year's budget and add (or subtract) a small percentage for things like inflation or expected growth.
\n• Pro: Very quick and easy to do.
\n• Con: It encourages Budgetary Slack (managers overestimating costs so they have an "easy" target) and ignores inefficiencies from last year.

B. Zero-Based Budgeting (ZBB)

Imagine you are moving to a new house. Instead of just packing everything you own, you start with an empty house and only bring in what you really need. That is ZBB! You start from zero every year and justify every single dollar of spend.
\n• The Steps: 1. Define Decision Units. 2. Describe Decision Packages. 3. Rank the packages. 4. Allocate resources.
\n• Pro: It cuts out waste and "zombie" projects that no longer add value.
\n• Con: It is extremely time-consuming and can be demotivating for staff who have to "defend" their jobs every year.

C. Rolling Budgets

A Rolling Budget (or Continuous Budget) is kept up to date by adding a new period (e.g., a month or quarter) to the end as soon as the current period expires. You always have a full 12-month plan ahead of you.
\n• Best for: Fast-moving industries where the future is uncertain.
\n• Pro: The budget is always relevant and up-to-date.
\n• Con: It requires a lot of administrative effort because you are "always budgeting."

D. Activity-Based Budgeting (ABB)

This focuses on the activities that drive costs. Instead of just budgeting for "Rent" or "Materials," you budget for the costs of activities like "Processing Orders" or "Setting up Machines."
\n• Pro: Gives a better understanding of what is actually causing costs to rise.

4. Beyond Budgeting

Some modern experts argue that traditional budgets are too rigid. Beyond Budgeting is a philosophy that suggests moving away from strict annual targets and instead using "Relative Targets" (e.g., "be better than our competitors" rather than "spend exactly \$10,000").

Analogy: A traditional budget is like a fixed GPS route. Beyond Budgeting is like using a compass—you know the direction you want to go, but you adapt to the obstacles as you find them.

5. Behavioral Aspects (The Human Side)

Budgets are set by people and affect people. This is where things get tricky!

Top-Down (Imposed) vs. Bottom-Up (Participative)

• Imposed (Top-Down): Senior management sets the budget and tells lower managers to follow it. It’s fast, but it can demotivate staff because they feel they had no say.
• Participative (Bottom-Up): Junior managers help create their own budgets. They feel more "ownership" and motivation, but they might try to build in Budgetary Slack (padding the budget to make it easier to achieve).

Common Pitfall: Budgetary Slack

Managers might say, "I think materials will cost \$110" even though they know they will only cost \$100. This extra \$10 is "slack." It makes the manager look good when they come in "under budget," but it is bad for the company because that \$10 could have been used elsewhere.

Summary Quick-Check Box

• Which budget is best for a stable environment? Incremental.
• Which budget is best for a fast-changing environment? Rolling.
• Which budget is best for cutting waste? Zero-Based (ZBB).
• What do we call "padding" a budget? Budgetary Slack.
• How do we flex a budget? Adjust variable costs to actual volume; keep fixed costs the same.

Don't worry if these names feel similar at first! Just remember: Incremental = Same as last year. ZBB = Start from scratch. Rolling = Keep adding months. Participative = Everyone joins in.
