“…Failures are often due to a mismatch between the project management capability and motivation, technical project understanding (Tan, 2004;Hillson, 2003) and with the project's managerial requirements (Crawford, 2000;Wysocki and Lewis, 2001). This is also compounded when the project management acts directly as an agent of the Client (Cerić, 2015), rather than as an independent or consultant engineer (FIDIC, 1999) for both the Contractor and the Client, thus, illustrating hidden intentions (Jäger, 2008).Leading a complex project therefore has implications for managing people and resources (Cavaleri and Reed, 2008). However, much leadership research attention has addressed an understanding of effective leaders (Yukl, 1999;James, 2005); but very little conducted on such leadership traits and behaviours associated with ineffective leaders (Kellerman, 2004), destructive leaders (Harris, Kacmar and Zivnusk, 2007) or toxic leaders (Rumsey, 2013).…”
