MODELS 2010 and using models to document designs

Jon Whittle and John Hutchinson attended the MODELS 2010 conference in Oslo, where Jon Whittle appeared on the Thursday's panel on "Modeling - Dos and Don'ts".
During the discussion, in an answer to a question from the day's keynote speaker, Pamela Zave, Jon mistakenly suggested that our data did not support the idea that the use of modeling to document designs was a significant factor in practitioners' use of MDE. In fact, our data does not support this assertion. When our questionnaire respondents were asked how "using models to capture and document designs" affected their productivity and maintainabilty:
  * 66% thought that their use of models to capture and document designs improved productivity
  * 61% thought that their use of models to capture and document designs improved maintainablity
In contrast, approximately 20% in each case thought that this use of models had no effect on productivity/maintainability, and approximately 6% and 11%, repsectively, think that using models in this way reduced productivity and maintainability. This leaves only 8-9% of respondents reporting that they have no experience of the matter.
