Ironically I actually worked for one. Operations team were windows only. Software team were java only. $12.2m wasted on not delivering an ERP system which was eventually replaced with SAP which cost twice as much and run on some Oracle stuff. SAP got replaced last year with custom software on .Net on AWS by 4 people in only 9 months. On the original project I was the Unix expert and not needed at all so I played Solitaire for 6 months and got paid for it.
