Management reports
A performance management system is only as good as the reports it produces. The right measures, badly reported, are ignored; the wrong measures, well presented, mislead. Syllabus area C is about those reports: whether they serve the organisation's mission and the people who read them, whether they drown readers in detail, whether their charts and commentary tell the truth, and how to write a commentary that helps managers act. In the exam, one of the Section B questions comes from area C. Typically you are shown an organisation's current report, with its tables, a chart and a commentary written by a manager, and asked to evaluate it, explain how it could mislead, and then improve it, often by writing a better commentary yourself. This lesson gives you a method for each of those tasks.
What a management report is for
A management report exists to help its readers decide and act, so that the organisation achieves its objectives. Different readers need different things.
| User | Decisions | What the report should give them |
|---|---|---|
| Board | Strategy, major investment, whether objectives are being met | A short summary of progress against strategic objectives and KPIs, trends, risks, and the decisions needed |
| Divisional and functional managers | Allocating resources, correcting performance within the plan | Results against budget and target for what they control, the reasons for variances, forecasts |
| Operational managers | Day-to-day control | Frequent, detailed, often non-financial data on output, quality, service and exceptions |
| External stakeholders reading an extract | Lending, investing, regulating | Measures they have asked for, on consistent definitions |
A report designed for one group usually fails the others: a board pack full of operational detail hides the strategic picture, and a summary dashboard gives a supervisor nothing to act on.
Evaluating a report: four tests
The study guide asks you to evaluate a report, including its narrative commentary, in the light of four things. Use them as your headings.
| Test | Questions to ask | Signs of a weak report |
|---|---|---|
| Mission, goals and objectives | Does the report measure progress against the organisation's objectives and CSFs? Does it reflect what the mission emphasises? | Only financial measures when the mission stresses service or quality; KPIs that have no target; no link between the measures and the strategy |
| Needs of the users | Is it relevant to the decisions the readers take, at the right level of detail, timely, understandable and focused on what they control? | Board receives line-by-line cost detail; managers judged on items they cannot influence; reports arrive weeks after the period |
| Information overload | Can readers find what matters quickly? | Dozens of pages and KPIs of equal prominence; raw data instead of analysis; no summary; every variance reported regardless of size |
| Best practice in presentation | Is it clear, consistent, comparative and honest? | No comparatives or targets; inconsistent units and periods; cluttered or misleading charts; commentary that repeats the numbers or contradicts them |
The remedies for information overload are worth knowing in detail: put a one-page summary first; report a small set of KPIs linked to the CSFs; use exception reporting, highlighting only results outside a tolerance, with red, amber and green status set by stated thresholds; move detail to appendices or an interactive dashboard that allows drill-down; and remove measures that nobody uses.
Best practice in presentation includes a clear structure (summary, key measures, analysis, risks, actions); comparatives against target, budget, prior period and, where possible, competitors; trends over several periods rather than one; consistent definitions, units and rounding; clear labels and sources; charts chosen for the message; and a commentary that explains rather than restates the figures.
Data visualisation
Visuals help busy readers see trends, comparisons and exceptions quickly. The study guide names charts, graphs, maps and animation.
| Visual | Best for | Risks |
|---|---|---|
| Bar and column charts | Comparing values across units or periods | Truncated axes exaggerate differences; too many bars clutter |
| Line graphs | Trends over time, actual against target | Dual axes can suggest relationships that do not exist; chosen start dates shape the story |
| Pie and stacked charts | Shares of a whole with few parts | Hard to compare slices; three-dimensional effects distort proportions |
| Scatter graphs | Relationships between two variables, such as cost and volume | Correlation can be mistaken for cause |
| Maps | Performance by location: branches, regions, delivery areas, shown by colour or symbol | Large areas dominate visually regardless of their importance; colour scales can be chosen to exaggerate |
| Animation | Showing how performance changes over time, such as branches moving on a chart of margin against growth quarter by quarter | Hard to read exact values; distracting; unavailable in printed packs; can impress more than it informs |
| Dashboards | Many KPIs at a glance, with drill-down | Can encourage watching everything and understanding nothing; thresholds behind the colours may be arbitrary |
A good visual is chosen for the question the reader needs answered, is accurately scaled and labelled, shows a comparison (target, budget, prior period), and is simple. A visual can also make poor data look authoritative, so the quality of the data matters as much as the design.
How numerical data can mislead
Figures can be accurate and still give a false impression. Look for these techniques, and for the honest alternative.
| Technique | How it misleads | Honest alternative |
|---|---|---|
| Truncated or stretched axes | A vertical axis starting well above zero makes a small change look dramatic | Start bar charts at zero; label any break in an axis |
| Selective comparisons | Comparing with a weak prior period or an easy budget makes results look strong | Show target, budget and prior period, and explain any change in the basis |
| Growth from expansion presented as improvement | Total sales rise because new branches opened, while existing branches decline | Report like-for-like figures for units open in both periods |
| Nominal figures in a period of inflation | Revenue rises in money terms while volumes fall | Report volumes, or adjust for price inflation |
| Percentages on small bases | A 200% rise in a tiny product line sounds significant | Give the absolute amounts alongside percentages |
| Averages that hide the spread | An average waiting time of eight minutes conceals customers waiting an hour | Report the range, the distribution or the percentage outside a standard |
| Cumulative figures | Year-to-date totals always rise, even when the latest month is poor | Show the latest period separately |
| Changes in definition | Reclassifying costs or redefining a KPI improves the measure without improving performance | Keep definitions consistent, or restate comparatives |
| Omitting measures | Leaving out the KPIs that have deteriorated | Report the agreed KPI set every period |
How a narrative commentary can mislead
Commentary is written by people whose performance it describes, so it is prone to bias, deliberate or not. The common forms are:
- Selective emphasis: good news first and at length, bad news brief or buried at the end.
- Attribution bias: successes credited to management, failures blamed on the economy, the weather or suppliers, without evidence that those factors caused them or that management could not have responded.
- Vague and loaded language: "robust performance", "challenging conditions", "impacted", "broadly on track", words that sound informative but are not quantified.
- Unsupported claims: "our strategy is working" or "we remain confident" with no evidence or forecast behind them.
- Restating instead of explaining: "sales rose 15% to $11.5 million" tells the reader nothing the table did not.
- Inconsistency with the data: commentary that describes a trend the figures do not show.
Writing a useful narrative commentary
A useful commentary answers four questions, in this order:
- What happened? The headline results against target and prior period, including the bad news, in a sentence or two.
- Why? The causes, supported by the data, separating what management controlled from what it did not.
- So what? The effect on the organisation's objectives and on future performance.
- Now what? The actions proposed, with owners and dates, and what the readers need to decide.
It should be concise, balanced, quantified, consistent with the figures, written in plain language for its readers, and focused on the measures that matter most. Explaining a few material items well is better than mentioning every variance.
Worked example
Scenario. Wuse Mart Co (fictional) runs supermarkets in Abuja. Its mission is "to be Abuja's favourite neighbourhood supermarket: always in stock, always fair value". The quarterly board report runs to 40 pages and 120 KPIs, each in the same type size. Its summary page contains a column chart of quarterly sales with a vertical axis starting at $9.5 million, and the table below. Three new stores opened in early 20X6. Average shelf prices rose by 12% over the year.
| Q3 20X6 | Q3 20X5 | |
|---|---|---|
| Sales ($'000) | 11,500 | 10,000 |
| Budgeted sales ($'000) | 12,000 | |
| Number of stores | 23 | 20 |
| Sales of the three new stores ($'000) | 1,600 | |
| Gross margin | 22.0% | 25.0% |
| On-shelf availability | 89% | 96% |
The regional director's commentary reads: "Q3 was our best quarter ever. Sales rose 15% to $11.5 million, a clear sign that our customer-first strategy is working, as the chart shows. Margins were held back by the challenging economic environment, which is outside our control. Availability was impacted by supplier issues. We remain confident of meeting our annual target."
Workings.
| Measure | Working | Result |
|---|---|---|
| Total sales growth | (11,500 − 10,000) ÷ 10,000 | +15.0% |
| Sales against budget | (11,500 − 12,000) ÷ 12,000 | −4.2% |
| Like-for-like sales (the 20 stores open in both years) | 11,500 − 1,600 = 9,900; (9,900 − 10,000) ÷ 10,000 | −1.0% |
| Like-for-like sales at 20X5 prices | 9,900 ÷ 1.12 = 8,839; (8,839 − 10,000) ÷ 10,000 | −11.6% |
| Gross profit | 11,500 × 22% = 2,530; 10,000 × 25% = 2,500 | +1.2% |
| Gross profit lost through the margin fall | 11,500 × (25% − 22%) | $345,000 |
| Chart: height of the bars above the $9.5m axis | 20X6: 11.5 − 9.5 = 2.0; 20X5: 10.0 − 9.5 = 0.5 | 20X6 bar four times as tall for a 15% rise |
Model answer extract (evaluation and revised commentary for the board).
Fit with the mission. Our mission promises two things, availability and fair value, but the report leads with total sales. Availability, our first promise, is buried among 120 KPIs and fell from 96% to 89%. The board cannot see from this report whether the mission is being achieved.
Skill: analysis and evaluation. The report is judged against the mission, using the first of the four tests.
Users and overload. Forty pages with 120 equally weighted KPIs is more than any board can use. The pack should open with one page showing eight to ten KPIs linked to our critical success factors, with targets and red, amber and green status on stated thresholds, and put the operational detail in appendices.
How the data misleads. The 15% growth comes from the three new stores. Sales in the 20 existing stores fell by 1.0%, and after allowing for 12% price rises, volumes in those stores fell by about 11.6%: fewer customers or smaller baskets. Sales were 4.2% below budget, which the commentary does not mention. The chart's axis starts at $9.5 million, so a 15% rise appears as a bar four times as tall.
Skill: scepticism. The headline is tested with like-for-like and real figures, and the chart's distortion is quantified.
How the commentary misleads. "Best quarter ever" is true only in money terms. The commentary credits the strategy for growth that came from expansion, and blames the economy for a margin fall without evidence; at least part of the cost of lower availability, lost sales, waste and discounting, is within our control. "Impacted" and "remain confident" are not supported by any figure or forecast.
Revised commentary. Sales of $11.5 million were 15% above Q3 20X5 but 4.2% below budget. All of the growth came from the three new stores, which contributed $1.6 million. Sales in our 20 existing stores fell by 1.0%, a volume fall of about 11.6% after price rises of 12%. Gross margin fell from 25.0% to 22.0%, costing $345,000 of gross profit. On-shelf availability fell from 96% to 89%, against our mission of being always in stock; empty shelves are the most likely controllable cause of falling like-for-like volumes, along with customers' reduced spending power. Unless availability recovers, the annual sales target is at risk. The supply chain director will report by 30 November on supplier performance and on restoring availability to 95% by the end of Q4, and the commercial director will analyse the causes of the margin fall by product category. The board is asked to approve a revised Q4 forecast at its next meeting.
Skill: communication. What happened, why, so what and now what, quantified and balanced, with owners and dates.
Common mistakes
- Evaluating the report in general terms ("it is too long") without tying each criticism to the scenario and its users.
- Recalculating figures without saying how they change the impression the report gives.
- Rewriting a commentary that simply restates the numbers, or that is as one-sided as the original in the other direction.
- Recommending more measures and more charts when the problem is overload.
- Ignoring the mission and objectives, which are the first test of whether a report is fit for purpose.
Exam technique
Read the requirement for the verbs: "evaluate" needs strengths as well as weaknesses and a conclusion; "advise how it could mislead" needs specific techniques applied to the figures; "prepare a commentary" needs the commentary itself, not advice about one. Use the four tests as headings for an evaluation. Do a few quick calculations that test the headline claims, such as like-for-like, real growth or performance against budget, and present them in a small table before you discuss them. When you write a commentary, follow what, why, so what, now what, and keep it to the length a busy board would read.
Study with AI
I am studying ACCA Advanced Performance Management (APM), management reports. Write
a short case with an organisation's mission, a table of results for two periods, a
description of a chart and a manager's narrative commentary that is misleading. Ask me
to evaluate the report, explain how the data and commentary mislead, and write a
better commentary. Wait for my answer, then mark it like an APM examiner and show a
model commentary.AI assistants can produce commentary that sounds polished but misstates the figures: check every number and claim against the data and these notes.
Lecturer's note: Before you criticise any report, ask what the reader is supposed to do after reading it. A board report that does not lead to a decision or an action has failed, however attractive it looks. Most misleading reports are not lies: every figure in the Wuse Mart report was true. They mislead through what they choose to compare, emphasise and leave out. So your job is to put the missing comparison back, like for like, in real terms and against budget, and let the numbers speak for themselves.
Key points
- A management report exists to help its readers decide and act; different users need different levels of detail, frequency and focus.
- Evaluate a report against the organisation's mission and objectives, the needs of its users, information overload and best practice in presentation.
- Charts, graphs, maps and animation help communicate trends and exceptions, but must be chosen for the question, accurately scaled and supported by sound data.
- Numbers mislead through truncated axes, selective comparisons, unadjusted inflation, growth from expansion, small bases, averages and changes in definition; commentary misleads through emphasis, attribution bias, vague language and unsupported claims.
- A useful commentary answers what happened, why, so what and now what, in a concise, balanced and quantified way.
Quick check
- A commentary says a new service grew by 200%. Its sales rose from $50,000 to $150,000, in a company with total sales of $20 million. Why could the statement mislead?
- Sales rose by 10% in money terms in a year when prices rose by 15%. What was the change in sales at constant prices?
- Which visual would best show the managers of a chain of 30 branches across the country where performance is weakest?
Answers
- It is a percentage on a small base. The increase is $100,000, only 0.5% of the company's sales; the absolute figures should be given alongside the percentage.
- 1.10 ÷ 1.15 − 1 = −4.3%: in real terms, sales fell.
- A map of the branches, coloured by performance against target, which shows geographical patterns at a glance; a ranked bar chart or table would give the exact figures.
