Aggregating Experience
Problems delivering User Centered Design

 
     
 

The merger of AOL/Time Warner/EMI makes a great deal of sense when you consider the difficulty rivals will have in delivering a competitive user experience on the web. The reason AOL has an advantage is simple, they have the ability to control the whole product and produce a coherent design. They have the desirable back end content from Time Warner EMI, the distribution mechanism through the AOL portal and the delivery mechanism with the Netscape browser. In short the ability to deliver an end-to-end user experience. So far without an equivalent competitor.

Why should it matter that AOL has all this control? What advantage might it give them? How might it affect the User Experience?

Firstly, we must put good User Centered Design aside for a moment, and face the reality that often the designer is asked to wrap an interface skin on to a system. Before the web arrived, this would entail devising a interface on a set of functions. Now this has morphed into a navigation scheme on a collection of content. Content driven design on the web for both wired and wireless web sites presents a much greater interface design problem than earlier function driven design did for GUIs.

Web Design vs GUI Design

There are a number of differences that UI Designers first recognizes when they make the switch to browser based interfaces. One of the main differences is the amount of information or content involved. The Web as a media device has been used to publish vast quantities of information and allow searching, sifting, and selecting of data in hitherto impossible quantities. In short, there is a lot more content involved in web design. So the degree of difficulty is greater!

As a UI Designer comes to terms with this, there is the double whammy that the environment for delivery of the interface is a lot less rich in terms of functionality and available widgets, unless the designer resorts to use of tools such as Flash or other plug-ins. Compensated for in some part by the deeper richness of graphic design and typography.

There is another hidden difference. It's a process difference. With GUIs the problem is usually contained within one single company. The back end business logic or data was also being generated by the same business. It was proprietary for the most part. The UI Designer was working for a company which understood the data and how it was used. They controlled it.

On the web, this is seldom the case. Particularly with portals and aggregation services, the content is often being delivered from a large collection providers. Each provider might be a vertical player who understands some business such as Weather, Stock Trading, News. The UI Designer is working for the portal which is in business to aggregate and deliver. It is a distribution function. So the UI Designer probably isn't an expert on the Content and neither are any of his/her colleagues. Nor do they control the content. Quite rightly the content provider will control it. They are the experts in the field whatever that may be e.g. weather.

So why is this a problem?

Understanding the audience

To deliver the best user experience, you need to understand the users - the audience for the content. Interaction Designers do this using well established, tried and tested techniques for user and task analysis. They create, devise or research, persona definitions for different users. They determine the user's goals and the tasks which need to be undertaken to achieve the goals. They determine the content required to complete those tasks and deliver the goals. Finally all of that knowledge is used to create what is often a procedurally oriented design. Good user centered design has a tendency to add value by identifying where functionality can be chained together to form a solution.

With a typical GUI application, the business or the technologists have identified a set of functionality which must be provided to meet basic business requirements. That functionality is provided from a back end server system and a client front end must be added. Without User Centered Design, you are simply grafting an interface on to the function. The resultant system does not explicitly support user tasks but does provide the necessary functionality. The user is required to know which functions to use and in which order.

The Interaction Design can add value to this by identifying the users and devising an interface which better supports tasks and goals. It's a higher layer of abstraction - a task layer on top of the functional layer.

Now, let us consider the problem for the designer of a wireless portal aggregation service.

The available functionality includes weather services, airline flight services, traffic services and news. Each of these comes from a separate provider, an expert in each field. They in turn are already offering these services as standalone functionality through their own web site. It already has an interface.

The designer has a choice. Simply, take all the available content and functionality and wrap an interface skin on to it and offer it as is, [ broadly speaking, what is offered on most current portals ], or try to understand the users and deliver goal oriented, task centered design. Choosing the second option will eventually deliver a better experience but not without it's problems.

The aggregator has a different audience

Sticking with weather services as an example, let's briefly consider who the originator of the content considers the audience? Typically, the originator is a business (often government owned) which collects weather data and makes reports and forecasts. These are delivered to news agencies, airports, fishing fleets and the like. In short, the content provider is probably only used to dealing with a professional audience.

The content tends to provide - "Just the Facts!". The interpretation of the facts is left to audience. For example, if I want to know whether it is safe to walk my dog, I need to know whether a thunderstorm is likely in the next hour. Weather information rarely gives this level of detail. In any case, answering the question would be left to me. The service provides the functional information but the goal oriented, tasked based inquiry is not supported.

Now consider that you are in the business of delivering compelling content to information appliance users over the internet.

A user for example might be a frequent business flyer. They want to know whether their flight is on time. They want to know what the weather is like at the destination. They need answers to questions like, "Should I pack an umbrella?","Do I need a winter overcoat?". They need to know how to get to their hotel from the airport. They need to know whether they will delayed in traffic.

The user has a goal of getting to the destination, in a timely fashion and suitably attired for the conditions. They don't know or care about isobars, or precipitation patterns, or flight codes, air traffic control slots and so forth.

These users are a lay audience with other things on their minds. So the designer has a problem. If the design is to cater for the audience, delivering user centered design, then the content must change. It must be suitable for the lay audience and not the technically savvy professionals. The problem is that the designer doesn't work for the content provider. Unless, of course, that designer is working for a large conglomerate such as AOL Time Warner EMI which provides much of the content such as news, music and entertainment, by itself.

Human communication and control

In order to deliver a coherent design offering the best possible user experience, the designer needs to be able to communicate with the owners of the content and needs to be able to control how that content is provided and presented. The designer needs to have influence over the back end.

Naturally, this is possible in most cases. The content provider is in business to make money. Naturally, they want to work with a aggregation service which is providing a distribution network for them. The key is speed and effect. When everything is contained within one corporate control, the ability to communicate, control and affect change is bound to be greater. In a world where time to market is as important as the quality of the product, it is obvious that an end-to-end internet service company has an advantage. When you control the delivery device, the distribution mechanism and the content, then naturally you have a time to market advantage because your people can communicate faster, better and more effectively than your competitors who are left behind negotiating legal agreements while you move your design forward. You can also affect a more coherent design earlier offering a superior user experience. As we move to a world where usage of services will be the key driver for revenue and as a result design and usability will be increasingly more important, it is obvious to see where the advantage lies.

Summary

Big end-to-end service providers like AOL Time Warner EMI have the opportunity to use their corporate size to communicate faster and exact better control over their designs, in comparison to competitors forming loose business alliances. Consequently delivering better product with a better user experience leading to higher usage and greater revenues. In an internet world where one leading player can quickly become a dominant force or even a virtual monopoly holder, you have to predict that the company that gets it right will dominate the market.

Delivering good User Centered Design with goal oriented, task centric services, aggregating content from across the internet is best achieved by big players acting alone.
