User Centred Design (UCD) Process Overview

31st July, 2008

In broad terms, User Centred Design (UCD) is a design philosophy and a process in which the needs, wants, and limitations of the end user of an interface or document are given extensive attention at each stage of the design process. This helps to put┬ácustomers at the heart of the online experience. By designing for users first and foremost, not only does the user experience improve (and thus, profit), but so does development efficiency and cost – designing based on user’s requirements means less redevelopment work is needed further down the line.
User Centred Design Process
In this post, we will discuss each phase of the UCD process, along with a summary of the services which are delivered during each phase.

Please note, some of the terminology used may not be too familiar to some readers, but rather than describing each service we wanted to keep this post more to the point. Feel free to call us for further information on a particular service or terminology used.

The 4 Phases of User Centered Design

You will notice that there isn’t an order assigned to the 4 phases, as UCD is a process of continual improvement. For the development of completely new business systems, applications and e-commerce platforms, the process would start with the analysis phase and work through the remaining 3 phases, but during the deployment phase on-going evaluation of the system and the users does mean that the process can then be continued, back in to the analysis phase (but to a lesser extent).

Variations in UCD methodology – what are yours?

There will always be slight variation’s in the process with other usability and software development agencies, and I’ll be interested to hear comments on these differences.

On saying this, one thing is for sure – when following User Centered Design principles, users need to be an integral part of the complete design and development process.
