A method involves identifying work elements of a work process which may be enhanced to provide a biggest impact on enhancing an overall value of the work process. The method involves identifying a plurality of work elements comprising a work process, interviewing one or more knowledgeable interviewees and determining existing states and enhanced proposed states of the plurality of work elements, visually displaying the existing and enhanced proposed states of the work elements, and estimating and visually displaying a change in value of the work process due to an enhancement of the work elements from the existing states to the enhanced proposed states.
