Well, given that it is much easier to destroy a system than it is to build one in the first place the actual method doesn&#x27;t really matter much. Take your pick. How would you sabotage a system?<p>In this case they canceled the contracts on a bunch of facilities that were crucial to operating the old system and that would take a very long time to set up again.<p>But the whole idea of a non-revertible change-over without at least a period of having the old system on stand-by just in case all by itself is totally reprehensible, <i>especially</i> since their testing regime was comprised mostly of &#x27;let&#x27;s go live and see if it works&#x27;. Of course they didn&#x27;t mention that little fact beforehand, only afterwards was it made clear that any attempt to move back to the old setup was going to be fruitless because they&#x27;d &#x27;closed the door behind them&#x27;.<p>I suspect that they knew full well the new system wouldn&#x27;t work properly and that if a revert would have been done this would likely trigger some serious backlash so by saddling the client up with the new system and making sure they could not go back they forced them to accept the new situation no matter what. Job security by any means.<p>Only that part ended up not working.<p>I&#x27;ve never seen a clusterfuck like this before and I really hope I won&#x27;t ever see one again.
