I think anyone who pays too much attention to industry pundits (and industry consultants) without doing their own homework would be better off investing in the proverbial Florida swampland.

When somebody else does your thinking for you the results are likely to be suboptimal.

What a wonderful world it would be if everything could just be written for a web browser. Web apps have some severe limitations and cannot be used for everything.
But hey, it must be that simple! I'll just go and reconfigure all the PLC's on our manufacturing lines to output everything in PHP.

You do know that php does not need to be run by a web server, right? It can be compiled for standalone apps.

Now, call me crazy, but since it's the PLC (Programmable Logic Controller) that is programmed, and programs are written in text, it just doesn't seem to me that it matters what the platform is. What's important here is that IT sees this as a way to lock out other platforms and then use that lockout to justify itself: We can't do it on the Mac because it doesn't have the software. Never mind that it doesn't have the software because we banned it.

Where I worked it was a common saying (even in Management) that a good manager could be replaced with someone tossing a coin with no reduction in decision quality.
So they tried to make decision-making easier. Almost coloring by numbers. Eventually the idea was to have "defensible" decisions rather than good ones. More effort went into making sure the decision followed the guidelines than ensuring it was a good one.
Then, in early 1992, they told us we didn't have jobs. Every decision leading to the company's demise was defensible.
It's a manager's job to make decisions. But making good decisions is hard. Owning up to bad ones is unpleasant. Being able to point to reports and studies that support your wrong decision helps no end.
