If a firm has more patentable drugs or copyrighted software than it can market, it can sell these patents or copyrights outright. As an alternative to selling off capacity, firms may want to leverage their economies of scale and of information. They can increase revenue by buying new customers through distribution channel acquisitions. This can also be seen in the current round of bank mergers, in that large banks exploiting ATMs and other IT find they can serve more customers. They then buy more banks to get access to those banks' customers.
Manufacturing is a strategic capability that can be similarly leveraged.
Smaller firms can access economies of scale by outsourcing manufacturing operations to large manufacturers, who pool many orders for the same widget into a single production run. A bottleneck is anything that limits an organization's ability to maximize tis revenue. This could be a machine that constrains output to be less than the market demand. However, if market demand is less than production capacity, then demand could be considered a bottleneck. Thus, final demand can be considered a bottleneck in the banking or entertainment value chain.
