As part of my professional and personal development, I just completed a 2-part course on business plans: how to write one, how to gather and analyze the necessary information, and how to incorporate it into your work – either for your own business, or as a guideline for how you see your role in an industry moving forward.
When asked to talk about where in the product/service life cycle books fall, I looked at the components that determine the sale of any product and decided that books fall into the mature and (hate this word) declining phase of the cycle. But then, as I talked about what it meant to work with a product that sits at that point on the curve, I realized that books truly ride the complete rollercoaster of product life. As one aspect of the industry or product declines, a new format, a new audience, new designs and product, and a new way of doing business opens up the cycle once again.
