My decade as a Business Intelligence consultant has been with large companies such as; Glaxo Smith Kline, Aviva, ICI and Orange.
From when I first started in the industry, the popularity of BI has leapt up as more and more companies have realised the value it can bestow.
This seems to mainly stem from ITIL, which is more suitable to larger companies.
The end result is that all the big firms are using Business Intelligence to forward their enterprise while the vast majority of smaller companies are oblivious to its existence.
During times of financial abundance, smaller firms missing out does not seem so bad. Of course the biggest companies will have access to the best resources, but now there is a recession (one which may take years to recover from).
The recession has not, in my experience, really hit the BI consultancy market. I suspect this is because the companies who know about BI, know it can rescue them, or at least keep damage to a minimum.
Now, people are losing their jobs, companies are failing and the idea of the smaller firms (which account for the majority of employment in the UK) missing out on a potential business saving service seems unfair.
A network of BI experts who have provided cutting edge consultancy for the biggest companies in the UK (and the world) are now offering this expertise and guidance to any company, any size that needs it at an affordable price.
