Plan product development and R&D
Explain the product-development process, sources of ideas and the role, cost and uncertainty of research and development.
Cambridge International AS & A Level Business 9609, 2026–2028 syllabus and 2029 syllabus, section 8.1.2. Treat forecasts and market estimates as uncertain evidence, and relate recommendations to the stated product and customers. Written practice is self-checked. Specialist review has not been completed for this lesson; these exercises do not award an official mark or establish exam readiness.
Before you begin
- Use the stated product, target market and period consistently; distinguish a forecast or model from a guaranteed result.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
What is one role of research and development?
What you will learn
- Describe a staged product-development process
- Identify internal and external sources of new ideas
- Assess why R&D matters and how to manage its cost and risk
Development turns an idea into a market offer
A product-development process may identify a customer need, generate and screen ideas, assess feasibility, develop a concept or prototype, test it, prepare production and launch, then review performance. A firm may repeat stages when testing reveals a problem.
Ideas can come from employees, customers, market research, suppliers, competitors, universities, technology changes or unmet needs. Screening should assess customer value, strategic fit, technical feasibility, cost, legal requirements and likely demand rather than selecting an idea solely because it is novel.
R&D supports innovation but consumes resources
Research and development can improve existing products, create new products or develop processes. It can help differentiate a business, respond to changing needs or build future capability.
R&D is uncertain: projects may fail, take longer than expected or be copied. Costs include people, equipment, testing and opportunity cost. A firm can use milestones, prototypes and customer tests to learn before committing to full-scale production, while protecting valid intellectual property and customer data.
Pause and explain
Why might a firm test a prototype before full production?
Worked example
A bicycle maker receives requests for an electric model. Explain how it could test the idea before investing in a full production line.
Show the worked solution
- Screen customer demand and strategic fit.
- Build or source a prototype and test performance and safety requirements.
- Pilot demand, cost and service assumptions before scaling.
Answer The maker could research customer segments and competitors, screen whether it has suitable battery and service capabilities, then develop a prototype. It should test range, reliability, safety and willingness to pay with a limited group, estimate production and support costs and use milestone evidence before committing to a full line.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A staff member proposes a refillable household-cleaner product. Give three sources of evidence the firm should use to screen the idea.
Give me a hint
Check customer need, operational feasibility and commercial fit.
Compare my reasoning
- Research customer willingness to adopt and pay.
- Ask suppliers about materials and refill logistics.
- Estimate safety, production, channel and support costs against the firm's objectives.
The firm could test customer need and willingness to pay, ask suppliers about safe refill materials and logistics, and estimate production, safety, distribution and support costs. It should also compare the concept with its brand and sustainability objectives before approving a prototype.
Look for these in your work
- Customer evidence is included
- Supply and operational evidence is included
- Strategic and cost fit is assessed
A new app feature passes a technical test but few pilot users try it. Explain two possible causes and a next step.
Give me a hint
Separate technical feasibility from customer usefulness and awareness.
Compare my reasoning
- The feature may not solve a salient user problem.
- Users may not discover or understand it.
- Interview users, review usage data and revise or stop against a milestone.
Technical feasibility does not establish customer value. Users may not need the feature, or they may not notice how to use it. The firm should interview pilot users and examine usage and task-completion data, then revise the feature or stop it against an agreed cost and adoption milestone.
Look for these in your work
- Two distinct causes are offered
- Customer evidence is proposed
- A decision threshold is identified
A firm must choose between incremental improvement and a major new-product R&D project. Recommend how it should compare the projects.
Give me a hint
Compare strategic value, risk, resource demand and learning milestones.
Compare my reasoning
- Estimate customer value and fit with future objectives.
- Compare cost, time, technical and launch risks.
- Consider staged investment, opportunity cost and measurable exit criteria.
The firm should compare each project's customer value and strategic fit with its cost, time and technical risk. A major project may create more differentiation but use scarce resources for longer. It can stage funding against prototype and demand evidence, consider the opportunity cost and define clear criteria to continue, revise or stop.
Look for these in your work
- Strategic and market value are compared
- Resources and risks are considered
- Milestones limit exposure
Common mistakes
- Treating an idea as proof of market demand
- Assuming R&D always produces a successful product
- Skipping testing because the concept appears technically possible

Develop or improve products and processes
R&D builds knowledge and tests possible innovations.

Make it stick
How do ideas move through product development, and how can R&D create value while the firm manages uncertainty?
