Abstract

Developing and delivering a project to an agreed schedule is fundamentally what project managers do. There is still an ongoing debate about schedule delays. This research investigates the development of schedules through semi-structured in-depth interviews. The findings reveal that half of the respondents believe that delays reported in the media are not real and should be attributed to scope changes. IT project managers estimating techniques include bottom-up estimates, analogy, and expert judgement. Impeding factors reported for the development of realistic schedules were technical (e.g. honest mistakes) and political (e.g. completion dates imposed by the sponsor). Respondents did not mention any psychological factors, although most were aware of optimism bias. However, they were not familiar with approaches to mitigate its impacts. Yet, when these techniques were mentioned, the overwhelming majority agreed that these mitigation approaches would change their schedule estimate.
