In a productive organization, the most efficient method for cutting waste is to attack anything and everything that is not done right the first time. The only drawback to SmartSheet is its ability to manage "data validation" like excel does. Even with column properties set as Date, users can still write stories "text entry". The same with dropdown lists, users can just types their own list with no validation! Some maybe suggest to use web-forms, but it is not an option when you manage a project you still need to access all tasks "lines" for progress updates. Or using maybe conditional formatting for validation which still against the "first time right" concept. I wish if SmartSheet consider this in their future road map.
