User Experience (UX) design is traditionally seen as the domain of user interface (UI) design, but within a software development team it should mean so much more! UX should permeate through the whole development team. It should influence the way middle tier developers’ craft their components and the way database administrators create their tables, stored procedures and views.

Within a software development team, most talk of creating a good “User Experience” usually relates to creating an intuitive user interface. In the traditional sense this means;
- The layout of the buttons,
- The ability for the application to remember contextual information,
- Or the intuitive nature of a web site navigation system,
but these interfaces, although important as the “face” of the application, are actually only a small part of what makes up the product.
Beyond the User Interface
A software application, like an iceberg, has a great deal of it’s complexity in the underlying structure of the program, the object model, where there are countless different members (interfaces, methods, and properties, delegates etc.) which transfer and transform data between objects and to and from the database.
While not as visible or as glamorous as the UI these are all interfaces that have users, your colleagues, whose needs must be satisfied.
On one level these “users” could be considered the most important users to satisfy because the culmination of their efforts make up the finished application, the ability for them to produce good software and the trade-offs they make in order to create the software will have a big influence on it’s character.
With this in mind the environment and the mind-set a developer works in is crucial to their ability to produce a good overall user experience. Every effort should be taken to ensure that they are focused on creating a good quality product, not in compensating for an awkward development environment or in acquiring the contextual information, from obscure code, that they need to complete their task.
Creating the right environment for UX to flourish
Every developer should be encouraged to develop this mindset; one way is to ensure that you create code that enables your colleagues to interface with it easily.
The simplest and most effective way of doing this is by naming your classes and members appropriately.
As a rough guide;
- Your objects should be named clearly.
- Your objects and their members should be named so that their intention is obvious.
- Your members should exist harmoniously within scope of the class they inhabit, as well as the overall application.
When the ambiguity is taken out of the development activity, the amount of tacit knowledge needed to complete a task is diminished and the communication between team members is simplified but it’s in the subsequent phases of the project when this clarity pays real dividends. Creating an object model that is clear and expressive reduce the amount of background information that has to be re-learnt and understood before starting a development task, allowing the developer to become productive quicker.
I intend to discuss this topic further, the theme that every opportunity should be taken to reinforce a user centric mind set is, I believe, critical to the development of good products. Only by cementing the “user” in all it’s forms as an integral part of the development process will the team truly understand what is needed to create a successful User Experience.
