A successful business playbook I keep coming across is turning cost centers into profit centers. That is, taking a problem that takes money to solve for one business, the solving it and offering it to other businesses that need it.
The best example is AWS. Amazon needed to solve the problem of high quality infrastructure to reliably host their ecommerce store. By making it available to everyone else, they ended up building a business that might end up being bigger than Amazon.
What are the cost centers in your business? If you concluded that you need to build it to properly solve it (build, buy, partner), might there be others interested in buying it?
