11. Department of Informatics, UC Irvine SDCL Collaboration Laboratory Software Design and sdcl.ics.uci.edu 11 Interleaving design behaviors Draw different kinds of diagrams Draw what they need, and no more – w.r.t. design at hand – w.r.t. notational conventions Refine and evolve sketches – increasing notational convention – appropriate sketches Use impromptu notations Move from one perspective to another Move from one alternative to another Move from one level of abstraction to another Perform mental simulations Juxtapose sketches Review progress Retreat to previous ideas Switch between synchronous and asynchronous work Explain their sketches to one another Bring their work together
