Can we make IT as flexible as consumer electronics?
I recently bought some new gadgets. I am usually reluctant to commit to new technology, but faced with rebellion from my family about our ancient TVs, the family computer, and a phone that they were embarrassed to see me with, I took the plunge and replaced loads of stuff. I bought a new Android phone, a large screen smart TV, a new PC, and a new PC monitor/TV.
From a functional perspective, these devices are very similar. The Android phone can do anything. The smart TV can access the internet and run apps. Using Skype I can make phone calls from the PC or the TV. I can play movies on any device and stream to any other. I can attach a keyboard to the TV and use it as a word processor. Even the "dumb" monitor runs Linux and can be hacked to run programs.
It is useful that any device can do anything. It gives a lot of flexibility, allowing you to rearrange devices as your needs change. You do not need to buy extra devices for features you do not use very often.
However, just because you can do anything on any device, it does not always makes sense to do so. Trying to use the web on the TV is not as comfortable as a PC. The built-in recording capability on the TV is not as functional as a dedicated machine. The phone isn't really cut out as a video streaming server. And so on. It makes sense for different devices to specialise in different ways.
Most business systems lack the flexibility of consumer electronics and are difficult to keep aligned with ever-changing business needs. To be more flexible, we need to adopt two principles:
This is hard. Traditionally, systems are acquired as narrowly focussed packages or from systems development projects with narrow requirements. System boundaries and functionality are an accident of history, and many systems are not self-sufficient. The overall architecture is very rigid, and is a major constraint on business change. And even where platforms are flexible (such as Microsoft Sharepoint), we don't have the methods to properly decide what each instance should do. If we want to make IT as flexible as consumer electronics, we need a new IT architecture.
