The head of the household in this movie was an efficiency expert. Businesses used to hire them all the time. This particular efficiency expert devoted his life to the study of such things. He found, for example, that it was considerably faster to button his shirt starting at the top and buttoning downward compared to starting at the bottom and buttoning upward. This little gem of knowledge in itself may not reduce clutter, but efficiency boils down to a maximum of output with a minimum of input, and it's a concept that's crucial to managing clutter.
Efficient storage reduces clutter by making it easier to replace things after each use.
If it's easier it's more likely to happen. Efficient storage means that what you need is close to where you use it or where you expect it to be. For example, if the recycling bins are in the far end of the garage, no one is going to use them. In the kitchen, move the silverware and plates to a drawer and cupboard between the table and the dishwasher. Put the glasses between the sink and the dishwasher.
