presentation quality

I was once told by Norman Foster during a critique in the modelshop of the Beijing Airport competition that a presentation is only ever as good as the worst drawing or board. A bad board will bring down the level of the rest of the presentation material.

Taking this to its logical conclusion, it is important to review all your presentation materials to ensure everything meets a minimum standard of quality. This will prevent your audience from believing that, for instance, your rendering company is good, but your plans and sections are rubbish - that's a big tick against you regardless how prepared your presentation material is. The best way around having rubbish material is to be a knockout presenter - like Norman.
