Compare competing products through a systematic product analysis using the same measurable criteria for each product. The comparison reveals strengths, weaknesses, and unmet user needs that can become opportunities for improvement.
In C3.1 Product analysis and evaluation, begin by selecting products that perform the same function or target similar users. Gather evidence through observation, measurement, testing, user feedback, manufacturer information, and disassembly where appropriate.
Next, establish comparison criteria linked to the product's purpose and intended users. Criteria may include:
| Criterion | Evidence to collect | Possible opportunity |
|---|---|---|
| Function and performance | Accuracy, capacity, speed, reliability | Improve effectiveness or consistency |
| Ergonomics | Comfort, reach, grip, anthropometric suitability | Improve usability or accessibility |
| Materials and manufacture | Material properties, processes, number of parts | Reduce waste, cost, or production complexity |
| Aesthetics | Form, colour, texture, and user response | Strengthen appeal for the target market |
| Sustainability | Product life, repairability, disassembly, disposal | Reduce environmental impact |
| Safety | Hazards, stability, protection, error prevention | Lower risk during use |
Use both quantitative data, such as mass, dimensions, or task-completion time, and qualitative data, such as user opinions about comfort. A comparison matrix can score each product against identical criteria, but scores should be justified with evidence rather than personal preference.
Then identify patterns. If every competing product is difficult to repair, repairability represents a market-wide opportunity. If one product performs especially well, it provides a that a new design should meet or exceed. Convert findings into clear design requirements, such as “the casing must be removable using standard tools.”
