The deliverables from the "phases" are often prescribed in standards or corporate guidelines. This metaphor, where understanding is packaged into documents, has been a cornerstone for our educational systems as well as for organizing engineering or social development projects. It is assumed that the understanding once achieved by the author(s) of the document will be transferred to its reader(s). In three longitudinal case studies of industrial development projects, a new view has evolved. The analysis team develops a capability to answer questions occurring on the fly, rather than writing down answers to initially stated issues.
