I work in banking and payment sector and I had a chance to observe this on a dozen projects.
In one instance Cognizant offered to completely automate a significant application used by hundreds of thousands of customers throughout the world. They were supposed to containerize half a dozen services, Oracle database, configure it to run on AWS and also automate environment creation.
The team put by Cognizant had not a single person knowing how to do basically anything. They spent entire project schedule and more just learning the basics of how to get around. Instead of automating anything they negotiated to be allowed to just order vms on EC2 and install applications there, manually. It took them three weeks to figure out how to copy 400GB database backup (they had space, accesses and networking, they just couldn't figure out how to copy the file). Then they spent another two weeks unable to restore the backup.
The trouble is that for a long time they have been cranking junior devs with no quality culture and no real interest in what they are doing and now this is starting to hurt them.
