“User-centered design (UCD) is a design philosophy where the end-user’s needs, wants and limitations are a focus at all stages within the design process and development life cycle”.
User-centered design (UCD) is a flexible process for software development projects that enables teams to more effectively meet the needs of users and customers.
The UCD process defines a series of collaborative activities that involves the entire product team, ideally including:
- Developers
- Solution managers
- Interaction designers
- User researchers
- Other key stakeholders
These collaborative activities take place in five distinct phases: Plan, Research, Design, Adapt, and Measure.
Keep in mind that the UCD process is flexible. If no interaction designer or user researcher can be assigned to a project, then the UCD activities can also be performed by solution managers and developers with the appropriate training. If some steps in the UCD process are not feasible, they can be left out. Clearly, the closer a development team sticks to the entire process, the better the results will be. But in the end, any UCD activity is better than none! Sometimes even small design activities can bring big rewards.
Research – Before you can design a product, it is imperative that you have a clear understanding of the users' goals and tasks, the market needs, and related work.
Design – In the design phase, you define your system from the users' perspective. Initially, this phase takes the form of use cases and an object action model, which describes the tasks that the system will support. From these tasks you create UI designs, beginning with rough sketches and ending with detailed UI design specifications.
Adapt – The adapt phase acknowledges that even the best conceived designs often need to be adapted when development begins coding. This adaptation can occur as a result of unforeseen limitations in the target technology, new requirements, or missing functionality in the initial design.
Measure – When the product is released, it is possible to measure its usability quantitatively. These tests measure a product's effectiveness, efficiency, and satisfaction.
Benefits of a User Centred Design
- Improves the acceptability and usability of systems and products and reduces cost and effort of fixing usability problems.
- Provides clear user and organisational targets for new systems and products against which design solutions can be tested.
- Ensures effectiveness, efficiency and user satisfaction are built into the overall design process.
- Improves buy-in of users and other key stakeholders.
