5. Discussion
When analyzing the research findings through a cultural lens, we have distinguished different practices of ex post governing in the PCEM. To begin with, we understood the public announcement of the bid winner as a transitional ritual. In this ritual, the ACP expressed certain values through the use of symbols, which were meaningful to both the ACP and the GUPC team: transparency (glass box) and confidentiality (National Bank, closed envelopes). Transition rituals have proven to be important in the progress of a project (Van den Ende and Van Marrewijk, 2014), and based on our findings, we suggest that the ACP’s public announcement of the bid winner ceremony can be understood as a cultural practice of governing. This ritual marks an important transition point, namely, the mutual commitment of client (ACP) and agent (GUPC) to execute the project. The ACP used the ritual to achieve the full commitment of the GUPC consortium to execute the megaproject for the agreed-upon very competitive price.
