Hmmmphhh.... a long time ago, I used to think the same thing. Then I went through a stage where these new fangled things called "PCs" came out (all this happened back in the '80s) and we did some remarkable stuff with downloading from the mainframes to create spreadsheet reports about potential new business and, of course, compared that with when contracts were going to end. I was the guy that put all those capabilities together and made it possible for the reporting to be auto-magic.
With due diligence, I read each report for each and every contract and saw something disturbing. I put together another spreadsheet to summarize it and determined the month that was 2 years out that business was going to be so bad that we'd need to lay off half of a 3,000 person workforce. It took it up the chain of command all the way to the GM... and every step of the way, I was told either "they're just estimates" or "you don't have a degree and you're not a CPA, so you don't know what you're talking about". The "town meetings" that the GM had once per month continued to forecast flowers blooming, lots of sunshine, and birds singing. The only mention of the new business forecasts was how much potential we had even though the forecast percent probability of winning the contracts was in the toilet.
On the very month that I had forecast, the GM had a town meeting where he identified that they were going to lay off half the work force.
A month after the layoffs, 3 people had died because they could no longer afford essential medications and several months later, several dozen people lost their houses because they could no long pay their mortgages. Most of them had kids, as well.
Yes... we're "saving babies"... and a whole lot more.
It's also why I say that "BI is an oxymoron".
