We have a philosophy that there should be no single point of failure for our shows. This applies to people as well as tech, but this document is going to concentrate on the tech. For people it means we both know how to do everything that needs to be done and every item in the main set of tech is light enough for either of us to carry unassisted.
With tech, when we say no single point of failure, we mean that if any single item gets broken or fails we have a workable solution that will allow the show to continue. This doesn’t necessarily mean a direct replacement, it means we have something else that can substitute for the broken item and we know how to apply it. It is acceptable that the replacement is not as good or as easy to use as long as it lets us present the show.
