When all your plans are just verbal and analytical, and the visual manifestation doesn't matter, whether you recognize it or not you have a visual literacy problem. And your project is going to be hindered by it. Cross-disciplinary impoverishment is the real issue here. In the corporate world this kind of cross-disciplinary teamwork is an incredible rarity, partly because not enough people have seen it work so they can understand the value of implementing it. Usually after it's too late.
Every corporation needs innovation and new solutions.
Part of the cost of coming up with a new solution is that you work in this different way. People need to express what they're doing both verbally and visually. Once people see a solution visualized, they realize that it's not what they thought, or they can see ways to improve it, or they realize that they don't like it. Making something visible is one of the best ways to control the outcome. You've externalized a representation that everyone can operate on.
