MACDADI IN AN HOUR debrief How things are Informal definition and management of project teams and goals How things could be Formal models of Teams Stakeholders Designers Decision Makers Goals Environmental Economic E it bl Equitable But information is project specific each team needs to define and manage Methodology We explain methods Represent Define Saturate Partition Weight to make more

Communicating AEC D Design Processses Haymaker CIFE CEE 215 Definning and Communicating AEC D Design Processses In about three hours we Established teams generated goals prioritized goals goals generated options options analyzed options evaluated tradeoffs selected an option option We also communicated all of this in formal models that can be broadly accessed and interpreted by a third party and potetnially a computer computer Haymaker CIFE CEE 215 Definning and Communicating AEC D Design Processses Models All Models are Wrong Some Models are Useful Haymaker CIFE CEE 215 Definning and
