Same people, same problems, same causes.
I've worked for both 3UK and TalkTalk, in the guts of the backoffice, around their respective launches. Interesting places.
3UK was summarized by one lark as "This chinese fella has a heap of money to spend, we may as well fill our boots". They had amazing problems at launch, and continued to do so long after. The 3UK management were described as "the Orange B-team"... Harsh, but fair.
A few years later, I came across the same people pulling together what was to become TalkTalk. Some of the juniors had become seniors, some of the people had left, and a few new people were thrown into the mix from Carphone. I tried to offer a few lessons learned, but no one cared. "We've done this before!", they crowed. "It's a reference design!", they bleated.
