I've sometimes wondered whether IT isn't becoming the 'core' part of a business. I.e. the one that's most complex and drives the competitive edge and success of a business. I have worked in IT in many different industries and often enough found the 'business' part of the business to be easy to pick up while it sometimes took ages and a lot of brainpower to get on top of the technology. In other words, IT people can understand 'businesss' but business people can't understand IT. So, in the future, instead of having a bank with an IT department, we'd have an IT company with a bank department. They'd probably switch sooner from banking to insurance than from one IT infrastructure to another.
I think amazon is a good prototype for this. It's a tech company that also sells books. They later added all sorts of other crap like electronics, then stuff that they don't even deliver but where they just act as a front for other retailers and finally they are now offering their IT services purely by themselves (S3, EC2).
I don't think IT will ever become that important. IT will just take its rightful place next to Law Firms and Accounting Firms as a necessary part of the business but not the core.
It is kind of surprising that IT, with its self references as fast-paced and innovative has taken so long to realize its own inefficiencies. IT (in the sense of internal computer systems for businesses) was greatly over invested starting in the 90s because the executives of the time were so scared. I remember stories of Hollywood executives who would ask their assistants to surf websites they were going to invest in and videotape it. They would take these video tapes home for 'research' the same way they would research actors, directors and movies to invest in. They completely didn't get it. So what did they do? They did what most people do when they are scared, they try to buy insurance. This insurance came in over-investment in all things technology both externally and internally, leading to huge IT departments that then used their bulk to buy more technology and increase their internal political might until all this over investment corrected itself in the legendary bubble pop.
I think when all is said and done, IT will be just like Payroll. When was the last time you met a person who works 40 hours a week processing payroll? They used to exist at every company - now everyone's checks come from ADP or PayChex. IT will be done by an outside company and will part of the budget for each person on the payroll. But of course I am a little biased...
Hmm, payroll - There is an industry to be disrupted...
I have a vague idea what you mean by the 'inefficiencies'. I am wondering whether these would have manifested in the first place if IT had been given a more central role. It's a lot about motivation too, the 'central' people in a business are usually motivated by being shareholders as well as employees at the same time. If you treat IT as just another accountant they will find endless means and ways to drag their feet and just generally pursue their own interests which are generally opposed to that of the business. Being linked into the flow of information, i.e. high level senior management decisions, is important too for efficiency.
I totally agree that things could always be better and that incentives are the key to this. There is a business concept from the 80s called 'open book management' where everyone in the company sees where all the money goes. This is more transparency than even public companies have.
I think it could be a technique that would get everyone from accounting to IT more involved in the business. I also think there needs to be much shorter expectations of how long someone will work for a company. Hollywood is on to something with the way they bring together small teams to make a film that then disband and reform in a new configuration for the next film. I wonder what would happen if every person in the company had to choose each year whether they want to continue with the company. They would in effect have a one year job. This might make their sense of urgency and priority for the 52 weeks within that year much more focused. It might also form a company with much more dedicated people who really want to be there.
