To all you "15 minutes is BS" skeptics...
...It's all about the corporate environment and network...
My personal tale... cue the wavy lines indicating that we're going back in time, although, not much...
---------------------------------
One time, we had an all-hands meeting scheduled for 08:00 sharp. Basically it was a "come to jesus" meeting because a milestone had been missed, bonus payments would not be forthcoming and therefore upper management need not spend lunchtime pondering the wonderful range of paint jobs that BMW offers.
We had a flexitime system back then, wherein the latest you could arrive for work was 10:00 am, so by specifying 08:00, it was made crystal clear that this was a serious event. Furthermore, we were told to bring along our current status, achievements, slippage etc. No problem - I'd collated this info into a tidy little spreadsheet the night before, all I needed to do was print it out.
I arrived at work a little later than I intended - about 07:40 - and switched on my PC.
[NB - the messages below are approximate in content and order. I was far too pissed-off to recall them exactly at a later date.]
"Applying security policy"...
"Updating system settings"...
"Checking user info"...(by now it was 07:50 and my fingernails were embedded in my palms)
Finally! A login dialog! I enter my details and hit return.
The login dialog kind of grays-out and sits there...
And still it sits there..
"Starting windows desktop"...
Sweet Jesus, a windows desktop at 07:55! But Wait - What's this?
Four dos boxes appear on the screen, all doing something or other and each sternly warning me not to touch the mouse or keyboard. Give me strength!
At 07:58 I get to interact with the required apps and fire off two copies of my status report. I got into the meeting last and at 08:01. The boss said, with not an ounce of humor, that it was good of me to turn up and is it ok if we start now? Not a good start...
Long, boring (although I was anything but bored at the time) but a real-life example of how achingly slow the corporate bootup / login process can be. If you have difficulty visualising my frustration and rage, have a look at "Office Space", specifically the part where Peter is trying to quickly shut down his machine and duck out early.
I'd never noticed or known how slow the process was before that day because I'd usually switch the machine on, then head off to the stand-alone network where the testing is carried out and get all those machines started up. By the time I'd done that and grabbed a coffee to take back to my desk the login prompt would be up and it would be a relatively short wait to get started.
To summarise: This shit really does happen.
Wouldn't it be great if IT could set up an intranet page so you could book a "wake on lan" for a set time each morning? Say, 20 minutes before you are likely to turn up...
