This paper discusses how a project should deal with its internal and external stakeholders who are associated with determining the project's objectives and uncertainty issues. Our experiences during 15 years of uncertainty assessment in many different sectors show that stakeholders are subjective and influenced by the objectives or effects of the project more than expected. This paper focuses on the relationship between the stakeholders and opportunities. We conclude that projects to a little extent find opportunities because risk and opportunities processes not are separated. From our point of view, projects can find and exploit opportunities and benefits to a greater extend if they use a defined opportunity management process. This paper has four parts. Firstly, rationality and methodology are presented. The method that we adopt is of qualitative nature. In the second part, relevant theories are described. Part three presents our ideas about the connection between stakeholders and uncertainty. And finally, conclusion and a description of further research wind up the whole discussion.
