"Successful businesses know exactly who their target customers are"

"Successful businesses know exactly who their target customers are. They strive to cater to specific and strategic customer needs. They focus on the most important customers to the business, and sometimes even refocus on a more lucrative target market. But it’s not uncommon for even successful businesses to become unfocused as they seek to grow by catering to a broadening spread of customer demands. And even with a conscious refocusing there are pitfalls; changing target customer isn’t easy and it doesn’t always go to plan.
...
Of course, it is quite possible to shift customer focus without disastrous results. Some years ago, I was CEO of a company that made trusses and frames for houses. The company was losing money and I had to confront a key business question: Who is our target customer? We had all sorts. Large companies that built hundreds of homes a year; mid-size builders who constructed several homes per annum; and “mums and dads” doing small projects who shopped mainly on Saturday mornings.
.
After some agonizing we narrowed our target customer down to “the professional builder.” Out went the mums and dads. They were a distraction. As a result, our product range shrank beautifully. I say “beautifully” because this refocus enabled us to reduce the stock of timber in our warehouse, thereby releasing cash and cutting our expenses. This refocus was one of the key ingredients in the turnaround’s success.

when you shift target customer you also shift the competitors you confront.

Identifying the target customer is a key part of strategic planning. The choice determines how what you sell, how you brand it, what price you charge, and whom you’re competing with. And as your strategy evolves, you may well discover that the customer focus of your business has shifted as well. It can happen without knowing. You cater for this acquisition here, you adapt to those regional markets there, and soon you’re trying to be all things to all customers. Or, ... you may make a change in customer focus without carefully considering the ramifications, and end up losing a packet because the strategy that goes with your new target doesn’t fit the new market you’re in. Either way, not paying attention to your choice of customer and what it implies is a recipe for strategic failure."
