It is true to say the public sector has hardly covered itself in glory with their ability to deliver projects on time, within budget and scope and to the right quality. PROMPTII, PRINCE and PRINCE2 were all introduced to address the common causes of project failure.
A project management method developed by Simpact Systems Ltd., PROMPTII, was a response to the outcry that many computer projects were overrunning on time estimated for completion and original budgets as set out in feasibility studies. It was not unusual to experience factors of double, treble or even ten-times the original estimates. PROMPTII was trying to set down guidelines for the stage flow of a computer project as follows:
In 1979, the UK Government's Central Computing and Telecommunications Agency (CCTA) adopted the method for all information systems projects. This led to PRINCE's development ten years later.
Published by the UK Government agency CCTA, Projects in Controlled Environments (PRINCE) became the UK standard for all government information systems projects.
The main features are:
A feature in the original method, not seen in other methods, was the idea of "assuring progress" from three separate, but linked perspectives:
However, the PRINCE method developed a reputation as being too unwieldy, too rigid and applicable only to large projects, leading to a revision in 1996.
An upgrade to PRINCE was considered to be in order and the development was contracted out but assured by a virtual committee spread among 150 European organisations. The BAC, TAC and UAC were removed in the official version. Most companies who adopt a PRINCE approach to project management adapt the method to their commercial environment and use those parts of PRINCE that work for them. This is acceptable as the puritanical days of sticking rigidly to a method are seen now as undesirable and unnecessary.
Originally developed for IS and IT projects to cut cost and time overruns; the second revision was made more generic an applicable to any project type.
In 2002 and 2005 PRINCE2 was updated in consultation with the international user community.
A major revision has seen the method made simpler and more easily customisable, a common request from users. The updated version has seven basic principles (not in the earlier version) that contribute to project success:
The updated method aims to give project managers a better set of tools to deliver projects on time, within budget and to the right quality.
