Usability and user-centred design entail a series of specific techniques that measure and improve interactive experiences of customers, employees, and users with websites, intranets or mobile devices.

The most frequently used techniques are:

• Usability tests
• Heuristic evaluation
• Iterative Prototyping
• Card sorting
• Qualitative interviews

This set of techniques offers a powerful combination of quantitative and qualitative methods that involve end-users in the process of designing an interface.

A qualitative interview, for example, allows us to build a detailed profile of the end-user of a specific interface. With this technique we can learn about the end-user's preferences, knowledge of technology, specific needs and habits.

Using this information as a starting point we can estimate the degree to which a user will adopt a website, software or mobile device. Then, we can identify improvement opportunities and implement specific solutions to improve the key ratios for each site or technological tool.
