Business Paper 1 — Marketing and People

Complete Worked Paper

#CODEX Complete Worked Paper — June 2019 (WBS11, Unit 1: Marketing and People)

Provenance (2026-09-28). Primary source read in full for this document, directly, not inherited from a summary: IAL_Business_WBS11_exemplar_responses.pdf (Issue 1, January 2020), the official Pearson exemplar-responses/mark-scheme booklet for WBS11 June 2019, held locally at ~/Documents/SOL/Old/REVI/BEESWAX/IAL_Business_WBS11_exemplar_responses.pdf and extracted with pdftotext -layout for this pass. Cross-checked against research/veridian/WBS11-verified-facts.md (§0 provenance, §2 assessment architecture) and content/veridian/curriculum/wbs11/paper-anatomy.ts, both of which independently identify June 2019 as the one WBS11 series this course's research holds a complete official mark scheme and level-descriptor set for. Also checked before writing: content/veridian/question-bank/wbs11.ts (covers Jan 2020, Oct 2020 and Oct 2022 series only — zero June 2019 overlap) and every file already in content/veridian/technique-hub/wbs11/, several of which cite individual June 2019 questions as isolated examples of a specific trap or mechanism — never as a full worked series. That gap is what this document closes.

#What this document is, and why June 2019

This paper's own technique-hub already has sixteen files. Several of them cite individual June 2019 questions — the Superdry PED calculation, the Ocado added-value Discuss, the smartphone design-mix Evaluate — as one example among several, in service of a specific trap or a specific spec point. None of them does what a "Complete Worked Paper" needs to do: take one real series, start to finish, and show a full worked model answer for every sub-question with an explicit, mark-by-mark account of how that answer earns its marks against the real mark scheme. This document does that, once, for the one series this course's WBS11 research can do it honestly.

June 2019 is that series for a specific, checkable reason, not by default. This pass's own read of the primary PDF confirms all eleven sub-questions are present with a full mark scheme — Q1(a) through Q1(e), Q2(a) through Q2(e), and Q3 — and that the four levels-marked questions (Q1(d), Q1(e), Q2(d), Q2(e)) and the one 20-mark essay (Q3) each carry their complete level-descriptor table, not just indicative content. WBS11-verified-facts.md and paper-anatomy.ts both independently flag June 2019 as the only series this course's archive holds that complete a set for — every other series in the archive (June 2022, January 2023, June 2023, January 2024, June 2024, October 2021) has real, verified mark-scheme material, but fetched question-by-question for whatever specific spec point a given lesson needed, not confirmed complete across all eleven sub-questions of one paper. Building this document from one of those instead would mean quietly inventing mark schemes for whichever sub-questions were never fetched — exactly the fabrication this course's standing discipline forbids. June 2019 is the one series where every sub-question can be shown honestly, with a real, checkable source behind each mark.

One source-PDF quirk, disclosed rather than silently worked around: the booklet's very last page footer (after Q3's content ends) reads "Unit 2 – Exemplar materials / Issue 1 – December 2019," inconsistent with the title page and every other page's footer, both of which say Unit 1. Every question, mark and figure cited below is checked against that question's own visible numbering and case-study content (Superdry, Ocado, the Samsung/Apple/Oppo/Vivo smartphone extract), not against that one footer line — flagged here as a known artefact of the source file, not a sign the wrong document was used.

#Paper structure, this series' own instance of it

Two hours, 80 marks. Section A (Q1, Superdry) and Section B (Q2, Ocado) each run an identical five-part climb — Define(2) → Explain-or-Calculate(4) → Analyse(6) → Discuss(8) → Assess(10) — for 30 marks apiece; Section C (Q3) is a single 20-mark Evaluate essay, this series set on Samsung, Apple, Oppo and Vivo in the smartphone market. 30 + 30 + 20 = 80, confirmed directly against this booklet's own printed mark allocations, matching the general structure paper-anatomy.ts already documents from the specification itself — this table is June 2019's specific instance of that already-documented shape, not a restatement of the shape's own mechanism. Where a mechanism (why Assess reaches Level 4 and Discuss cannot; why the second sub-question isn't reliably a calculation) is already explained elsewhere in this paper's material, this document points to it rather than re-deriving it, and spends its own space on the thing no existing file has: a full worked answer and a full mark map, for every one of these eleven questions.

#Section A — Question 1 (Superdry)

#Q1(a) — Define 'qualitative research' (2 marks)

The question is keyed to a specific line of Extract A on Superdry's market research; the extract itself is not reproduced here.

Model answer. "Qualitative research is market research collected on consumers' opinions, attitudes and beliefs, gathered through methods such as interviews or focus groups rather than as numerical data."

Mark-by-mark. Mark 1 for correctly identifying what the research is about — opinions, attitudes or beliefs, not facts or figures. Mark 2 for a second, genuinely distinct idea, not a restatement of the first — here, naming how it is collected (interviews/focus groups) or contrasting it with numerical/quantitative data [MS-Jun19, Q1(a)]. The confirmed real trap, already covered in this paper's signal-topic-brief-meeting-customer-needs.md, is stopping after the first idea — a response naming only "views, opinions and feelings" with no second distinct idea scores 1 of 2 [EXM-Jun19, Q1(a)]. That trap is not re-derived here; this entry exists only to show the technique that avoids it inside a genuine full answer.

#Q1(b) — Calculate PED for a Superdry t-shirt (4 marks)

Model answer, with working shown.

% change in quantity demanded = (150,000 − 120,000) ÷ 120,000 = +25%.
% change in price = −10% (given).
PED = % change in quantity demanded ÷ % change in price = 25 ÷ (−10) = −2.5.

Mark-by-mark. 1 mark for identifying the correct formula (% change in quantity demanded ÷ % change in price); up to 2 marks for correctly selecting and calculating the two percentage changes (+25%, −10%) from the given figures; 1 mark for the final calculated value. The mark scheme explicitly protects the sign: a final answer of −2.5 earns all 4 marks, while 2.5 without the negative sign earns 3 of 4, because PED is inherently negative given the inverse relationship between price and quantity demanded [MS-Jun19, Q1(b)]. This exact sign-dropping trap already has its own confirmed row in codex-deep-dive-demand-supply-and-elasticity.md's cross-series ledger — cross-referenced here, not re-derived; this entry's own job is showing the working that earns all 4 marks cleanly, including the negative sign as a genuinely separate, deliberate step rather than an afterthought.

#Q1(c) — Analyse two methods of primary research for Superdry (6 marks)

Model answer. Superdry could use customer surveys to gather direct, structured feedback on what shoppers want from the range — for example, whether customers feel the current range is too masculine-skewed and would buy more if a wider feminine range existed. Knowing this lets Superdry design and stock ranges closer to actual demand, which should increase sales and help the brand stay competitive against rivals who already serve that gap. Superdry could also run focus groups to gather richer, qualitative data on how customers perceive the brand — for instance, discovering that customers value garment quality and durability more than low price. This lets Superdry justify positioning itself as a premium, quality-led brand rather than competing purely on price, which supports higher margins on each sale.

Mark-by-mark. Up to 2 knowledge marks for correctly naming two distinct primary-research methods (surveys, focus groups) — or, alternatively, for a correct definition of primary research itself. Up to 2 application marks for tying each method to a Superdry-specific finding rather than a generic one (the feminine-range gap; the quality-over-price perception). Up to 2 analysis marks for a distinct, developed consequence per method (adapting the range to sell more and stay competitive; sustaining a premium price point) [MS-Jun19, Q1(c)]. The confirmed real failure mode here — already documented with a full worked example in codex-deep-dive-meeting-customer-needs.md — is naming two methods and two generic consequences without ever tying either one to a Superdry-specific finding, which caps a response at the four knowledge-plus-analysis marks and forfeits both application marks [EXM-Jun19, Q1(c)]. The model answer above is built specifically to avoid that: each method's sentence carries a Superdry-specific finding before its consequence.

Model answer. Superdry's profit share plan is a financial incentive, sharing part of the company's profit with its roughly 4,500 employees over a three-year scheme, with the actual amount tied to job role [MS-Jun19, Q1(d)]. For most employees this should raise motivation: knowing that extra effort could translate into a real financial bonus gives staff a direct stake in the company's performance, and it signals that the employer values staff enough to share success with them rather than keeping it solely for shareholders — both are classic drivers of effort and loyalty. However, the scheme is sharply role-weighted: a full-time shop employee might receive around £2,000, a shop manager around £28,000, and senior executives up to £300,000 [MS-Jun19, Q1(d)]. For the shop-floor majority of the 4,500-strong workforce, a reward two orders of magnitude smaller than a senior executive's could easily read as unfair rather than motivating, particularly if those employees feel their own day-to-day effort has little influence over company-wide profit. A second, independent limitation: because the scheme only pays out if Superdry is actually profitable across the full three years, there is no guarantee of any payout at all — for an employee who doesn't expect the company to hit that bar, the scheme may change nothing about how they actually work. On balance, the plan is likely to raise motivation unevenly rather than uniformly: most effective for staff close enough to the reward, and closest to profit-driving roles, to feel it is meaningfully theirs; weakest for the shop-floor staff for whom both the size of the reward and its dependence on a distant three-year outcome make it feel abstract.

Mark-by-mark, against the level-descriptor bands. Level 1 (1–2) would be reached by isolated, recall-based knowledge with weak application. Level 2 (3–5) is reached once knowledge is applied accurately and a chain of reasoning is attempted, even if one-sided or under-developed. The model answer above is built to clear Level 3 (6–8): it carries two separate, developed chains of reasoning (financial reward → felt value → effort; role-weighting → perceived unfairness → possible demotivation for the majority) rather than one asserted point, and closes with a genuinely balanced assessment that uses the extract's own quantitative detail (the £2,000/£28,000/ £300,000 spread) rather than a generic "some may, some may not" line [MS-Jun19, Q1(d)]. The single most-repeated real trap on this exact question — already fully documented in forge-error-pattern-tracker.md and signal-topic-brief-motivation-and-leadership.md — is answering the impact on Superdry (higher productivity, lower turnover) rather than the impact on employees, which the question specifically names; every sentence above is anchored to how the employee experiences the scheme, not how the business benefits from it, for exactly that reason.

#Q1(e) — Assess the extent to which the Boston Matrix may help Superdry compete in the clothing market (10 marks)

The question itself states plainly that "T-shirts and hooded tops are Superdry's cash cows" [QP-Jun19, Q1(e)].

Model answer. The Boston Matrix classifies a firm's product range by market growth and relative market share, into cash cows, stars, question marks and dogs, and its main practical use is guiding where cash should be invested. Superdry's t-shirts and hoodies, as stated cash cows, sit in a low-growth, high-share position — generating reliable revenue without needing heavy new investment. That cash can then fund higher-growth ranges, such as a new seasonal or snow-focused line, positioning those newer ranges as potential stars if they gain share in a growing segment, or flagging them as question marks needing a promotional push if share is still low. The matrix also gives Superdry a structured basis for discontinuing genuinely underperforming lines classified as dogs, freeing resources rather than continuing to fund them by habit. However, the matrix has real limits that cap how far Superdry should rely on it. It is only a snapshot of the current portfolio at one point in time, with no predictive power — it cannot tell Superdry how fast a rival might erode the cash cows' own share, or how quickly fashion tastes might move away from a product entirely, both of which matter more in clothing than in slower-moving markets. Classifying a line as a dog also does not automatically mean discontinuing it: a product generating acceptable revenue, or supporting brand image, may still be worth keeping even at low share and low growth. On balance, the Boston Matrix gives Superdry a genuinely useful, simple starting framework for allocating investment across an existing range, but it needs to be paired with something that tracks change over time — most obviously, product life cycle analysis — precisely because fashion is a market where today's cash cow can lose its position faster than a static share/growth snapshot would ever reveal.

Mark-by-mark, against the four-level scheme. This question's own level scheme adds a fourth band above Discuss's ceiling, and the mechanism for why is already fully explained in paper-anatomy.ts — not re-derived here. Applied specifically to this answer: it reaches Level 4 (8–10) by closing on a stated, supported judgement (the matrix is useful as a starting point but needs pairing with product life cycle analysis specifically because of fashion's pace of change), not merely by listing the matrix's strengths and then its weaknesses side by side without resolving them [MS-Jun19, Q1(e)]. The real confirmed ceiling on lower-scoring responses, evidenced directly in this booklet's own graded exemplar commentary, is reaching Level 3 by correctly categorising products and analysing consequences but never attempting the assessment step at all [EXM-Jun19, Q1(e)].

#Section B — Question 2 (Ocado)

#Q2(a) — Define 'online retailing' (2 marks)

Model answer. "Online retailing is the selling of goods or services to consumers over the internet, rather than through a physical shop."

Mark-by-mark. Mark 1 for identifying the core activity (selling goods/services to consumers). Mark 2 for a second, distinct idea — specifically, the internet/website as the channel — not a bare repetition of the word "online" from the question itself [MS-Jun19, Q2(a)]. This exact sub-question does not appear to have a dedicated citation anywhere else in this paper's technique-hub material at time of writing — genuinely new coverage added by this document, not a restatement of an existing entry.

#Q2(b) — Using Extract D, explain one way changing fashions, tastes or preferences affected demand for Ocado (4 marks)

Model answer. More consumers have shifted their grocery-buying habits toward buying online rather than in physical supermarkets. For Ocado specifically, this shift shows up directly in its own figures: online grocery revenue rose from around £680m to around £1,258m, and weekly deliveries rose from around 120,000 to around 230,000 orders — a 92% increase — over the period covered by the extract [MS-Jun19, Q2(b)]. As more consumers made this shift, Ocado received a growing volume of orders and a correspondingly higher revenue, directly benefiting from a change in consumer buying habits it did not itself have to create.

Mark-by-mark. 1 knowledge mark for correctly identifying the underlying shift (more consumers buying groceries online). Up to 2 application marks for using two genuinely distinct pieces of the extract's own data to support it — here, the revenue figures and the delivery/order-volume figures are kept as two separate data points rather than one restated twice. 1 analysis mark for the consequence for Ocado specifically (more orders, more revenue) [MS-Jun19, Q2(b)]. The confirmed real trap on this exact question — already documented in forge-exam-technique-guide.md and forge-error-pattern-tracker.md as the paper's general "thin Explain" pattern — is developing one application point at length rather than including a second, genuinely distinct one; the model answer above is built with two separate figures specifically to avoid that, cross-referenced here rather than re-argued.

#Q2(c) — Analyse two advantages for Ocado of having cost efficiency as a main business objective (6 marks)

Model answer. One advantage is that lower operational costs let Ocado offer more competitive prices. Online grocery made up only around 6% of the UK grocery market at the time, forecast to grow to around 9% by 2021 [MS-Jun19, Q2(c)] — a still-small but genuinely price-sensitive segment, so being able to undercut or match rival prices without sacrificing margin should help Ocado win a larger share of that growth as it happens. A second, separate advantage is that reducing waste directly raises profit margins on the orders Ocado already fulfils. Those higher margins give Ocado more retained profit to reinvest — funding the warehouse and delivery-fleet expansion it needs to keep pace with a market still expected to grow for several more years, rather than relying on external funding to do so.

Mark-by-mark. Up to 2 knowledge marks for defining cost efficiency or naming two distinct advantages of minimising cost (lower prices possible; higher margins). Up to 2 application marks for grounding each in Ocado's actual market context — the ~6%-to-~9% growth figure specifically. Up to 2 analysis marks for a distinct consequence per advantage (competitive pricing → market-share gain; higher margins → funded expansion) [MS-Jun19, Q2(c)]. signal-topic-brief- entrepreneurs-objectives-and-choices.md and codex-deep-dive-entrepreneurs-objectives-and-choices.md already document that this exact question was, in the real examiner report, poorly answered because many candidates could state cost/waste reduction but could not convey the actual consequence for Ocado [PEF-Jun19]. That finding is not re-derived here; the model answer above exists specifically to demonstrate the consequence step those weaker responses missed, for both advantages, not just one.

#Q2(d) — Discuss the extent to which Ocado has been successful in adding value to its business (8 marks)

Model answer. Added value is the gap a business creates between what a product or service costs to provide and what customers are willing to pay for it. Ocado has built several real, specific sources of added value into its home-delivery service: colour-coded bags, hourly delivery-time slots, and text reminders naming the driver [MS-Jun19, Q2(d)] — none of these are necessary to deliver groceries at all, but together they differentiate Ocado from a plain, unbranded delivery service. That differentiation is plausibly linked to Ocado's own growth: the same rise in online orders and revenue already seen at Q2(b) is consistent with customers choosing Ocado specifically because these features make the service feel more reliable and personal than a generic alternative, which should support both repeat purchase and a degree of price tolerance. However, added value is not free to create. Ocado's in-house delivery and logistics technology represents a real, ongoing investment, and offering a wide choice of hourly delivery slots means some delivery vehicles run under-full at less popular hours — reducing the capacity utilisation of the fleet and raising the average cost per delivery. If those costs eventually have to be passed on as higher prices, that risks undermining the very value Ocado has built, in a market where customers can and do compare grocery prices directly. On balance, Ocado's added-value strategy appears successful on the revenue side — the order and revenue growth is real and measurable — but its cost side is less clearly resolved, since the same features driving that growth are also the ones adding to Ocado's own cost base.

Mark-by-mark. This reaches Level 3 (6–8) through the same structure as Q1(d): two developed chains of reasoning (differentiation → growth; feature cost → margin risk) rather than one, and a balanced assessment that weighs both rather than asserting success alone [MS-Jun19, Q2(d)]. This exact question already has a table entry in codex-deep-dive-meeting-customer-needs.md and a shorter citation in codex-definitions-and-application-bank.md (line 642) — both correctly name the convenience-versus-cost counterbalance this model answer uses, but neither builds the question's full worked answer or its mark-by-mark account; that is this entry's own addition.

#Q2(e) — Ocado sells products online, delivered to customers' homes. Assess the importance of place in Ocado's marketing mix (10 marks)

Model answer. Place is one of the four elements of the marketing mix, covering where and how a product actually reaches the customer. For a business built entirely around online sale and home delivery, place is not one input among several — it is close to the whole business model: without a working delivery operation, Ocado has no way to fulfil an order at all. That dependence shows up directly in the extract's own figures: on-time deliveries fell from around 95.3% to around 94.9% in 2016 [MS-Jun19, Q2(e)] — a small percentage shift, but a real risk to repeat custom given that Ocado sells perishable goods to customers who have specifically chosen a delivery hour, so a missed window is a more serious failure for Ocado than for a retailer selling non-perishable goods through a shop. However, place cannot be assessed in isolation from the rest of the mix. The online grocery market is genuinely price-competitive, so excellent delivery reliability paired with uncompetitive prices would not retain customers either; equally, Ocado's product range needs to match the breadth and quality customers would find in a physical supermarket, or reliable delivery of a worse range still loses to a competitor. Taking both sides together, place is the most structurally central element specifically for this business model — Ocado's entire value proposition depends on delivery working — but that is a claim about Ocado's particular case, not a general ranking of place above price, promotion and product; those three remain necessary, not optional, once a customer is choosing between Ocado and a rival on any given order.

Mark-by-mark. Level 4 (8–10) requires the assessment to be "wide ranging and well contextualised" and to reach "a supported judgement," a mechanism already fully explained at Q1(e) above and in paper-anatomy.ts, and applied here specifically: the judgement is qualified ("for this business model," not a general ranking) rather than a flat, unqualified claim that place always matters most [MS-Jun19, Q2(e)]. This exact question is already cited in signal-topic-brief-marketing-strategy- and-product.md and signal-topic-brief-promotion-pricing-and-distribution.md, both correctly as the paper's one real, confirmed anchor for distribution/place content — again, this entry's own addition is the full worked answer and mark map, not a new finding about the question's evidentiary status.

#Section C — Question 3 (Samsung, Apple, Oppo, Vivo — smartphones)

#Evaluate which of function, aesthetics or cost of manufacture is the most important design-mix element for smartphone manufacturers (20 marks)

Model answer.

Function. A smartphone's function — reliability, call and data quality, battery safety — is close to a baseline requirement rather than a differentiator, because failure here is catastrophic in a way the other two elements are not. Samsung's Galaxy Note 7 suffered exactly this: reports of the device catching fire in users' hands [MS-Jun19, Q3], a functional failure serious enough to damage trust in the brand well beyond the affected model. That argues function is the most important element, since no amount of good aesthetics or low manufacturing cost rescues a product that actively harms the people using it. Against that, function has a ceiling: once quality reaches a level users trust, further functional improvement yields diminishing returns and can even work against a manufacturer commercially, since a phone reliable enough that owners do not feel they need to replace it limits repeat sales in a market that depends on a replacement cycle.

Cost of manufacture. Price has become a central battleground in the smartphone market, and price is set substantially by manufacturing cost. Oppo and Vivo grew their market share by selling phones around $250, a price made possible specifically by a lower cost of manufacture [MS-Jun19, Q3] — putting real competitive pressure on established players. Samsung's own response, offering a range of phones at different price points, shows that even a market leader has to treat manufacturing cost as a live strategic lever, not just a background constraint, to defend share across the full price range rather than only at the premium end. The obvious limit on this argument is that cost of manufacture cannot be pushed so far that it compromises function or safety — the Note 7 episode again stands as the clear warning of what happens when a manufacturer's priorities shift too far from build quality.

Aesthetics. A phone's appearance functions as a visible status symbol as much as a specification sheet does, and for some consumers, recognisability and design are the deciding factor at the point of purchase [MS-Jun19, Q3], independent of the underlying hardware. But aesthetics is the most easily and cheaply imitated of the three elements — a distinctive look can be closely copied by a rival within a product cycle or two, in a way a genuine manufacturing-cost advantage or a reliability record cannot be — so any edge aesthetics provides is generally the least durable of the three over more than one generation of devices.

Judgement. Weighing the three together: function sets the baseline a manufacturer cannot fall below without serious commercial damage, and aesthetics offers real but comparatively short-lived differentiation. Cost of manufacture is the most decisive of the three specifically because it is the one factor that determines whether a manufacturer can compete across the full width of the market at all, not only at one price tier — Oppo and Vivo's entry at the $250 price point shows a manufacturing-cost advantage can convert directly into market share against established rivals, while Samsung's own multi-tier pricing shows that even the market leader has had to organise its strategy around cost of manufacture to defend that width. The recommendation that follows is not that function and aesthetics stop mattering, but that a manufacturer's cost-of-manufacture strategy should be set first, with function held to a non-negotiable safety and reliability floor underneath it, and aesthetics used as the differentiator layered on top once both of those are secured.

Mark-by-mark, against the four-level, 20-mark scheme. Level 4 (15–20) requires all three options to be covered with well-developed, logical chains of reasoning, a full awareness of competing arguments leading to balanced comparison, and — the specific requirement this model answer is built around — "an effective conclusion that proposes a solution and/or recommendations" [MS-Jun19, Q3], not merely a stated preference among the three. Each of the three body paragraphs above both makes the case for its element and states that element's own limit, and the closing judgement explicitly ranks and sequences all three (cost of manufacture first, function as a floor, aesthetics layered on top) rather than naming a single winner and dropping the other two. This exact question already has a one-sentence application citation in codex-definitions-and- application-bank.md (the Note 7 / Oppo-Vivo pairing, lines 705–710) — correct as far as it goes, but a single applied example, not a full essay-length worked answer with its own mark map, which is this entry's own addition.
