The IPA agreed that creating a culture of transparency and openness are the foundations of effective project delivery. It promotes these values within its principles of project success, namely “Prioritise people and behaviour” and “Tell it like it is”.35 It used Crossrail as an example, where people at the working level understood the lack of progress with systems integration, but this information did not get passed upwards in the organisation. Creating trust within organisations requires leadership; leaders must be willing to hear bad news in order to instil the right behaviours in their teams.36
