A product is the good or service offered to satisfy a customer need. New-product development turns evidence about a need into an idea, design/prototype, test, modification and launch; each stage reduces uncertainty before larger resources are committed.
| Offer decision | What it means | Why it matters |
|---|---|---|
| good | tangible item that can usually be owned and stored | design, inventory, transport and physical quality matter |
| service | intangible activity/benefit, often produced and consumed together | employee/customer experience, consistency and capacity matter |
| packaging | container/presentation that protects, identifies, informs and helps sell a good | affects damage, convenience, legal information, differentiation, cost and environmental impact |
| Phase | Typical sales pattern | Appropriate management focus |
|---|---|---|
| introduction | low, beginning to rise | build awareness/trial; secure distribution; monitor feedback |
| growth | rising quickly | expand supply/distribution and defend differentiation |
| maturity | high but growth slows/levels | retain loyalty, differentiate and control cost |
| decline | falling | extend, harvest, reposition or withdraw |
Extension strategies aim to delay decline by finding new markets or uses, changing features/packaging, promoting differently or adjusting price. They can renew interest but cost money and cannot make demand grow indefinitely.
| Boston category | Market growth | Relative market share | Portfolio implication |
|---|---|---|---|
| star | high | high | invest to sustain growth; may become a cash cow |
| cash cow | low | high | generate cash that can support other products |
| question mark | high | low | decide whether investment can build share or whether to exit |
| dog | low | low | review for withdrawal, harvesting or a defensible niche |
The life cycle describes one product's sales over time; the Boston matrix compares portfolio position using market growth and relative market share. Neither model proves profit or dictates a decision—use costs, cash flow, competition, strategic fit and reliable market definitions too.
Price affects demand, revenue, positioning and contribution toward cost. Choose a strategy by connecting the product, objective, customer sensitivity, costs, competition and stage of launch—not by treating low or high price as automatically best.
| Strategy | How it works | Suitable when | Main risk |
|---|---|---|---|
| cost plus | add a markup to unit cost | costs are known and the business seeks a planned margin on cost | ignores demand and competitor prices; sales are not guaranteed |
| penetration | launch at a low price, then raise it later | entering a competitive market and seeking trial/share quickly | low margin; customers may resist the later increase |
| competition | set price with reference to rivals | offers are comparable and customers can switch easily | may not cover the firm's costs or express differentiation |
| skimming | launch at a high price, then reduce it | innovative/distinctive offer with early customers willing to pay | limits early demand and attracts competition |
| promotional | temporarily reduce price or offer a deal | stimulate short-run trial, traffic or sales | lower margin and sales may fall when promotion ends |
sellingprice=unitcost+markupamount
If unit cost is £40 and the business adds a 25% markup on cost, markup = £40 × 0.25 = £10 and selling price = £50. This protects a margin on each unit sold only if the cost estimate is complete and customers actually buy.
A launch may combine strategies over time—for example penetration followed by a sustainable regular price. Judge expected volume, unit margin, brand position, cash needs and likely competitor response.
Penetration and promotional pricing both use a lower price, but penetration establishes a new product/market then raises price, while promotional pricing is a temporary deal. Cost plus adds a percentage of cost; it is not the same as a profit margin percentage of selling price.
Place is how and where customers can obtain the offer. The distribution channel must deliver the required reach, convenience, speed and service at a cost and level of control the business can sustain.
| Channel | Advantages | Limitations | Best fit depends on |
|---|---|---|---|
| retailer / physical outlet | customers can see, try or receive personal service; established footfall and immediate possession | rent, staffing and retailer margin; limited opening hours/location; less producer control through an intermediary | need for experience/advice, local demand, product handling and retailer coverage |
| e-tailer / e-commerce | wider geographic reach, 24-hour ordering, customer data and potentially lower premises cost | delivery/returns, cybersecurity, platform/website cost, no physical trial and intense online comparison | customer digital access, delivery economics, trust and product suitability |
A producer may sell through other retailers for rapid access to their customers, sell directly online for reach and control, or combine channels. A small specialist shop might retain an experience-led outlet while adding e-commerce and local delivery.
Evaluate the whole route: customer convenience can raise demand, but delivery, returns, retailer discounts, stock availability and channel conflict affect cost, margin and reputation. Monitor service quality across every channel.
E-commerce is a sales/distribution channel, not merely online promotion. Removing a physical shop does not remove all costs: fulfilment, packaging, delivery, returns, systems and digital marketing remain.
Promotion communicates with a target market to create awareness, interest, trial, purchase or loyalty. Select a method by the segment's media behaviour, the message, objective, reach, credibility, timing, cost and ability to measure response.
| Method | Useful role | Main limitation |
|---|---|---|
| advertising | paid message with broad or targeted reach | cost, clutter and exposure do not guarantee purchase |
| sponsorship | associates the brand with an event/person/cause and audience | reputation risk and effect can be hard to isolate |
| product trial | reduces uncertainty by letting customers experience the offer | sampling cost and trial may not become repeat purchase |
| special offer | creates urgency or short-run value | reduces margin and can train customers to wait for deals |
| branding | creates a recognisable identity and promised experience | needs consistent delivery and continuing investment |
| public relations | manages relationships/news to improve company or brand image | less control over coverage and credibility can be damaged quickly |
| Route | Meaning/examples | Strength and boundary |
|---|---|---|
| above the line | paid mass-media promotion such as television, radio or broad press | wide reach, but costly and less individually targeted |
| below the line | more direct/targeted activity such as direct mail, sales promotion, events or trials | more focused/measurable, but usually narrower reach |
| targeted online advertising | uses audience/behaviour data to deliver selected ads | relevant and measurable; depends on data quality, privacy and platform rules |
| viral social advertising | users share content rapidly | low-cost scale is possible, but reach/message cannot be controlled |
| e-newsletter | permission-based updates to known contacts | supports repeat purchase; lists, relevance and consent must be maintained |
A strong brand helps recognition, differentiation, trust and loyalty and may support repeat purchase or a price premium. It is built by consistent product/service experience as well as promotion; a logo or campaign cannot compensate for weak delivery.
Match method to segment: a specialised audience may be reached efficiently through targeted content or sponsorship, while a broad consumer product may combine mass advertising with offers and digital reminders. Track suitable outcomes such as reach, response, trial, sales and repeat purchase against cost.
Above/below the line describes the promotional route, not whether it is good or bad. Public relations seeks image and relationships rather than guaranteed sales, and online targeting/viral reach may exclude audiences, create privacy concerns or spread negative responses.
