This paper reviews the greatest problems of project management as stated by people employed in the process and other industries in Western Europe. Their statements indicate that the greatest problems are in organization, time and resourcing projects. By contrast, risk, quality and safety are not stated to be major problems. There are only relatively small differences in these results between the process industries and other industries, and between different types of employer. There are also only small differences in the greatest problems of large compared to small projects, and the problems do not appear to change over time. The data indicates that many of the problems could be reduced or eradicated. The data also confirms what should be the core topics for the assessment and training of project managers.
