Project management information systems (PMIS) are widely regarded as an important building block and today’s project management. The nature of these systems has changed considerably during the last decade they are in fact still developing from single-user single-project management systems to complex, distributed, multi-functional systems that no longer only cover project planning. Information systems research has to date only partly reflected this PMIS evolution. Typical fields of research are algorithms in respect of operation research problems related to project management, the assessment and comparison of commercial project management solutions and corresponding assessment frameworks, the development of prototypes to test new kinds of functionality and research into the usage of project management software systems. Two specific problems are very rarely addressed, PMIS are become increasingly complex. Therefore, firstly, information system designers are facing a growing number of business processes that have to be supported with project management software. Secondly, information system users have difficulties in setting up corresponding organizational systems and selecting corresponding software products PMIS are become increasingly complex. This paper deals with some important literature reviews regarding PMIS.
