Interfacing with the cloud

I was having a breakfast meeting with a technology start-up CEO last week, and the discussion turned to user experience and interfaces. He asked me, "What is the best interface you've worked with?" I started thinking through this, focused on my computer, and provided a couple of examples. He nodded, then said, "I'm surprised you didn't mention this", gesturing at our iPhones. After a second or two, I realized the reason I hadn't thought of the iPhone is that I never think of my iPhone - I just use it.

More than Palm's old tenet of "if it takes too many taps, we need to rethink it", the gold standard for interface design should be that the end-user does not need to consider it at all. Rather, the end-user should be so comfortable with using the interface that the focus can then turn to the actual function or process the interface is supporting.

What does this have to do with cloud? Leaving aside the computer-to-computer interfaces so important today, we still have an immense number of Software as a Service (SaaS) applications available for end-users to purchase and consume. Often, these are contrasted with more traditional enterprise applications on the dimensions of cost and feature set, but I think SaaS providers have (and take) an opportunity to also differentiate on interface design, for the following reasons:

1. The interface is the thing for customers - The ongoing consumerization of IT means purchasing decision-makers are not necessarily IT people, but line-of-business managers who assess based on functional needs rather than infrastructure integration. They don't see the software install, database, or infrastructure - they see only the interface shown to them. By removing the infrastructure from the discussion (other than to demonstrate its ability to provide a reliable service), SaaS providers can focus attention on the user interface and how well it will meet those functional needs.
2. User feedback is embraced and quickly acted on - Because the application is not distributed to many independent customer infrastructures, it can be updated as often as needed to meet customer requests. For instance, Rally Software, offering a SaaS Scrum project management application, uses Scrum and releases updates every 6-7 weeks; the updates come directly from customer requests.

I realize this is nothing new, and interface design has always been important. But we still have so many interfaces still incredibly non-intuitive and difficult, getting in the way of actually getting things done, even as the iPad, Android tablets, and even Windows 8 offer a new way to think about how to interact with any application. Hopefully as cloud computing becomes increasingly mainstream in the large enterprise, decision makers will demand the gold standard of interface design ("I just use it") and the market will respond accordingly.
