Business Paper 3 — Business Decisions and Strategy

Error Pattern Tracker

Provenance (written 2026-09-28): built from research/veridian/WBS13-verified-facts.md, read in full (2,057 lines). That file mines exam-board material to varying depth across many separate passes and states a different series-count denominator for almost every individual claim — this document preserves whichever denominator each specific pattern below is actually backed by, rather than flattening everything to one paper-wide number. Material is drawn from at least a dozen distinct exam series (Oct 2021 through Oct 2025); two series (Oct 2025, and to a lesser extent the Superdry/Mears Group material within it) are sourced in the facts bank from a third-party mirror because the official qualifications.pearson.com URL could not be located despite systematic probing — that file's own provenance notes explain the independent verification steps taken, and any pattern drawn from that series is flagged inline below. forge-exam-technique-guide.md, signal-frequency-and-boundaries.md and codex-definitions-and-application-bank.md in this same folder were also read in full to check for overlap before writing a single line here. content/veridian/question-bank/wbs13.ts was checked too — its three real questions (resistance to change, transformative leadership, SWOT) are the same three primary sources already cited below, not independently re-derived.

What this document adds that nothing else in this folder does: forge-exam-technique-guide.md §4 already lists this paper's confirmed traps as a compact, cross-referenced reading list, organised by category. This document does not restate those explanations — it turns the same underlying, confirmed patterns into something a student logs their own timed-practice mistakes against, attempt by attempt, so the patterns stop being a list read once and start being a record of what a specific student actually keeps doing wrong.

Citation key: a short quote (under ~15 words) appears only where the examiner's or mark scheme's exact phrasing is itself the identifying detail of the pattern; everything else below is paraphrased in this document's own words, with the series, question and tariff named so the claim can be traced back to WBS13-verified-facts.md and, from there, to the primary PDF. No likelihood percentage or grade boundary is stated anywhere in this document — every frequency claim is stated as "confirmed in N of M series checked," using the facts bank's own stated denominator, and where a pattern is backed by only one document that is said plainly rather than implied to be more.


WBS13 FORGE — Error Pattern Tracker

Business decisions and strategy (Unit 3). A fillable log for timed-practice mistakes, pre-populated with this paper's own confirmed, primary-source error patterns so you log against real categories from the start, not invented ones.

How to use this

  1. After every timed practice question or paper, look at what you actually lost marks on. Find the closest-matching code in Part 1 (technique/command-word mistakes, true regardless of topic) or Part 2 (topic-content confusions, grouped by spec sub-section). If nothing matches, log it anyway under OTHER with your own short label — a real gap this document has no primary-source evidence for yet is still worth tracking.
  2. Add one row to the log in Part 3 for each mistake, using the next free row number. The SEED rows above the blank ones are not your mistakes — they are Pearson's own confirmed version of that category, so you know exactly what you are matching against. Leave them in place; add your own rows below them.
  3. Every few papers, tally Part 4. A category with three or more of your own entries is a genuine, personal recurring weakness — a count from your own log, not a guess — and belongs at the top of your next revision session.
  4. When you run out of blank rows, copy the table header and keep going. This is a template, not a fixed-length form.

Part 1 — Technique / command-word categories

Mistakes in how you answer a given tariff, independent of topic.

CodeCategoryConfirmed source
CALC-1Calculate: % sign omitted on a percentage-ratio answer, capping the mark one below fullOct 2022 ER (Q1a/b); Jan 2025 ER (Q1a) — 2 of 6 mined series explicitly
CALC-2Calculate: ×100 left out of a ratio formula, losing the Knowledge mark even when the final figure is rightOct 2022 ER (Q1a); June 2022 ER exemplar tip — 2 of 6 mined series explicitly
CALC-3Calculate: answer not rounded to the number of decimal places the question specifiesJan 2023 ER (Q1b); June 2023 ER general note; Jan 2025 ER (Q1a/1b) — 3 of 6 mined series explicitly
CALC-4Calculate: the unit left off a non-percentage figure (e.g. "cars per employee")Oct 2025 MS Q1a, Tesla labour productivity — confirmed in this one mark scheme's own award-of-marks note; not yet corroborated by a second series for this paper
CALC-5Calculate: ARR formula not known, or confused with simple payback (answer given in years/months instead of a %)Jan 2022 ER Q1a, Bramwell Brown — real candidates "confused ARR with simple payback"
CALC-6Calculate: YED formula inverted — income placed over quantity instead of quantity over incomeJan 2025 ER Q1b, Spotify — candidates "reversed the YED formula"
GEAR-1The gearing ratio formula not known at allOct 2022 ER and Jan 2025 ER, two non-adjacent series, both independently reporting candidates "did not know the gearing ratio formula at all"
EXP-1Explain (4): answer opens with a bare definition of the stakeholder/term instead of the way, reason, impact or aim the mark is actually forJune 2023 ER Q1a, Lush — same warning repeated near-verbatim in Oct 2022 ER, June 2022 ER and Jan 2025 ER (4 of 6 mined series carry this exact caution)
DISC-1Discuss (8): only one side argued, ignoring the command word; or an unneeded conclusion added where none is requiredOct 2021 ER Q1c, IAG/Air Europa — many candidates gave a one-sided response despite the Discuss command word
ASS-1Assess (12): answer ends with no stated judgement — a real, repeated conclusion gap, not a one-offConfirmed independently across four separate series/questions: Oct 2021 ER (BA), June 2023 ER (Lush/ESO), Oct 2023 ER (Five Guys), Jan 2024 ER (Patagonia)
HOL-1Attempting evaluation is treated as sufficient on its own for a top level, rather than the marking being holistic (depth and balance, not a checklist of Assessment Objectives attempted)Near-identical wording confirmed in every examiner report read for this paper: Oct 2021, June 2022, Oct 2022, Jan 2023, June 2023, Jan 2025 (6 of 6)
APP-1Extract content copied or paraphrased into the answer rather than used as evidence for an argumentConfirmed on two separate, non-adjacent real questions: Oct 2021 ER (British Airways, contingency planning) and Oct 2023 ER (Disney, resistance to change)
FRAME-1A taught framework (e.g. Ansoff's Matrix) reached for reflexively even where the question did not ask for itJan 2025 ER Q1d, Spotify/Audible — some candidates' responses were steered toward Ansoff's Matrix rather than the business's own stated intentions
TECH-1A technique (e.g. CPA) evaluated generically rather than tied to the specific, named company in the questionSummer 2024 ER Q3, Burger King — a genuine 18/20 exemplar lost marks on an underdeveloped conclusion, not on the arithmetic

Part 2 — Content-confusion categories, by spec sub-section

3.3.1 Business objectives and strategy

CodeCategoryConfirmed source
331-1Ansoff's Matrix answered about the wrong initiative in the extract, not the one the question namedJan 2023 ER Q1d, Brompton Bikes — some candidates assessed the new factory, museum and e-bikes instead of the bike-hire launch the question actually asked about
331-2External economic influences answered as a generic PESTLE walk-through, with no real business theory attachedJan 2023 ER Q3, Dr Martens — many candidates did not understand what "external economic influences" meant and worked through PESTLE's components with no theory behind them
331-3SWOT answered as a bare description, without addressing what the question actually asked (the benefit of using it)Summer 2024 ER Q1d, Bosch — some candidates did not read the question carefully and produced a SWOT analysis rather than discussing its benefit to strategy
331-4SWOT assumed to require all four quadrants covered to reach the top bandConfirmed false: Summer 2024 ER Q1d, Bosch — not necessary to cover all four aspects of SWOT to reach Level 4

3.3.2 Business growth

CodeCategoryConfirmed source
332-1Economies of scale named or listed without explaining the mechanism of why each one actually occursJan 2023 ER Q1c, Brompton Bikes — weaker candidates stated or listed types rather than explaining the mechanism

3.3.3 Decision-making techniques

No content-specific miscoding beyond the two formula-confusion errors already logged in Part 1 (CALC-5, ARR/payback; CALC-6, YED inversion) — both are this sub-topic's own confirmed candidate errors and belong in the technique table because the underlying mistake is procedural (the wrong formula), not a conceptual misunderstanding of the technique itself. Log them under those two codes when the mistake happens on a 3.3.3 question.

3.3.4 Influences on business decisions

CodeCategoryConfirmed source
334-1Task culture reduced to "organising work into tasks," missing the actual mechanism (cross-departmental staff on a specific project, returning afterward)Oct 2022 ER Q2, Zappos.com — the ER's single clearest misconception in the whole facts bank: Task culture "is not just about organising work into tasks"
334-2A financial-rewards question misread as "which employer is better," rather than evaluating the importance of financial rewards itselfJune 2022 ER Q3, Amazon vs Levi's — some candidates misread the question this way
334-3John Lewis Partnership's employee-ownership structure misunderstoodJan 2025 ER Q3 — "misunderstood by a minority of candidates"
334-4Employee share ownership's link to labour turnover argued through the productivity/motivation mechanism, not the turnover-specific one (voice, and a reward that only pays out to whoever stays)June 2023 ER Q1d, Lush — candidates who "focused mainly on productivity" were marked down; the higher levels needed a direct link to retention specifically
334-5Financial rewards' link to labour turnover argued through productivity/motivation instead of the turnover-specific mechanism — the same shape of error as 334-4, confirmed a second time on a different questionOct 2023 ER Q1d, Five Guys — candidates who focused on productivity or motivation rather than turnover specifically were marked down

3.3.5 Assessing competitiveness

No content-specific miscoding beyond the two technique errors already logged in Part 1: GEAR-1 (gearing formula not known — confirmed twice, Oct 2022 and Jan 2025) and EXP-1 (Explain answered with a bare definition instead of the way/reason/impact/aim). Log them under those two codes when the mistake happens on a 3.3.5 question.

3.3.6 Managing change

CodeCategoryConfirmed source
336-1Contingency plan's own meaning not known — the answer instead discusses the consequences of the risk event itselfOct 2021 ER Q1d, British Airways — "many candidates did not know what a contingency plan was"
336-2Extract content copied or paraphrased rather than used as evidence — confirmed within this topic specifically (also logged paper-wide as APP-1)Oct 2021 ER Q1d, British Airways
336-3Resistance to change's own meaning not understood — the answer narrates events/organisational structure insteadOct 2023 ER Q3, Disney — many candidates did not fully understand what "resistance to change" meant, and the question's performance was markedly weaker than the adjacent Q2
336-4"Good leadership" discussed generically where the question specifically named transformative leadershipJan 2024 ER Q1d, Patagonia — the higher levels needed the focus kept on the transformative leadership style specifically, not leadership in general

Candidates checked and rejected for this document. Two real, quotable examiner-report findings were considered and left out, for the same reasons the facts bank itself gives: (1) Bosch's Q1(e) commentary on Ltd-company benefits (candidates listing characteristics rather than addressing growth impact) is genuine, but legal structure is not itself a named WBS13 spec point in 3.3.1–3.3.6, so it has no honest category to sit under here. (2) Patagonia's Q1(e) commentary on candidates copying extract text is real, but it is the same mechanism APP-1 already covers, not a distinct one — adding it as its own code would inflate the count without adding a genuinely new pattern.


Part 3 — The log

SEED rows are Pearson's own confirmed pattern for that category, not your mistake — they show you what you are matching against. Add your own rows below them, numbered onward. "Root cause" is your own one-word-or-phrase diagnosis: term confusion, misread the ask, missing mechanic, technique/AO structure, over-generalised a rule, no conclusion, or your own label.

Part 4 — Your tally

Fill this in after every few practice papers by counting your own numbered rows in Part 3 (not the SEED rows) against each code. Leave a category blank until you have actually logged something against it — an empty cell means "not yet tracked," not "not a risk."

Reading this table honestly: three or more entries against one code, from your own timed practice, is a real personal pattern — go re-read that code's full mechanism in its cited series before your next paper (the mark scheme's or examiner report's own wording is quoted or paraphrased above; the full teaching treatment lives in the matching curriculum lesson, cross-referenced by spec number in content/veridian/curriculum/wbs13/). One or two entries against many different codes is normal variance, not yet a pattern worth a dedicated session. This document cannot tell you which of your own future mistakes will matter most — only your own filled-in count can do that.
