The Metrolink in Manchester,[0] the UK's largest tram network, is a good counter-example. The expansion of the network been consistently well delivered over the last ~decade. The Airport Line opened a year ahead of schedule,[1] the Trafford Park line eight months ahead of schedule,[2] and the Second City Crossing was only a year behind it's aspirational opening date because of the discovery of a crypt buried under where a new station was being built.[3] I think this is mainly because there has been a pipeline of new projects enabling both the contractors and TfGM to retain skilled engineering and project management staff.
