Participatory conversation in PD

1) The user-participants assume that their knowledge of actual rather than ideal organizational processes is "anecdotal" and irrelevant. TO avoid seeming foolish to the technical people, they do not challenge formal statements of work or ask fo r technical clarification. They aren't clear about possibilities and limitat ions of the system-to-be. 2) The software engineers feel satisfied that, as they develop a logically connected procedure description and the users agree with their version o f it, they have enough information to proceed. AvOidable problems then surface after implementation.
