A company is like a bridge. The job of a bridge is to support the weight of what crosses it. But if a particular deck or arch or beam or joint or bearing fails to do its own job, the bridge can fail and will catastrophically. Perhaps some beams hold more weights than others, but can any bridge be composed entirely of decks or entirely of arches or entirely of beams? Perhaps, but we do not see many of them. It is always possible to innovate in the design of bridges, but if most of the great bridges in the world all have a mix of decks and arches and beams and joints and bearings, instead of simply being composed of solely beams or solely joints, then we might begin to wonder if this composition is not accidental to the proper functioning of a great bridge, but essential to it, even if we are not particularly interested in or proficient in the Art of Being Another Part of the Whole.
