Priorities may shift as the context evolves and as more information becomes available. Initially, prioritization is done at a higher level of abstraction. As the requirements are further refined, prioritization is done at a more granular level and will incorporate additional bases for prioritization as they become appropriate. ¹

Stakeholders may not agree on the specific prioritisation. This is why it is important to agree with all stakeholders on the IIBA Basis for prioritisation in business analysis. All stakeholders will have there own agenda and working through the prioritisation stage with them using the defined prioritisation basis is important.
