Interoil from it's inception started with an idea of not just one person PM but several. It took many engineers, technicians and business people to bring the refinery from Alaska to PNG to make it functional and paying and creating a customer base.
Understanding the geomorphology of PNG and the people of PNG was definitely not PM.
It takes a community. Leadership can only take a community so far. PM had a certain skill set.
As shareholders we will never know what happened over the last several years with IOC and its interactions with PNG, Shorts, Banking Interests, Outside Interests (Sabotaging perhaps IOC's plans), Civelli and internal management struggles.
PM should be commended for work that he performed and also work he did not do but there were many many others who had the skill sets to bring to the table to bring IOC to where it is today. One person did not do it all.
One should take another good read at the MS piece. It makes no mention of past or future management practices nor a comparison between PM and Hession and talks about the company as a whole and the future direction.
