The aim of the Prompter project was to develop the Prompter tool, a “decision-support tool to assist in the planning and managing of a software project”. Prompter has the ability to help software project planners assimilate best practice and 'know how' in the field of software project planning and incorporate expert critiquing which will assist project planners in solving the complex problems associated with the planning of a software project.

This paper identifies the strategies that experienced information systems (IS) project managers say they use to cope with requirements-uncertainty (RU) when managing development projects for external clients. It is shown that project managers (PMs) claim to use different strategies for coping with the different dimensions of requirements-uncertainty, as this notion has been formulated in IS literature. Based on this finding, it is proposed that perhaps requirements-uncertainty should be formulated as a profile construct, and not as a latent or aggregate construct, if it is to have pragmatic validity as a guide to action for project managers.
