In present situation, for a company to be in profits, they need to accept the importance of project management and change accordingly. As of now, the executives are more concerned about their positions and are not far sighted. There are teams that are managed by managers who would like to continue to maintain the reporting structure and power.
In my opinion, waiting for long time to develop an EPM system results in communication gap within the staff and also bad cooperative culture in the company.This delay is also due to the fear of losing power and control over their reports. All these are some of the significant reasons for not considering of developing EPM.
