Today I was reminded of a quote by Yvon Chouinard, founder of the outdoor clothing company Patagonia:

There are no three-star French restaurants with fifty tables.

It's pretty simple. A chef who serves five customers (instead of fifty) can spend more time on each meal, so the results are tastier and the customer's experience is more personal.

The same is true for software. Five features with perfect implementation is more useful than fifty features with poor implementation. Sometimes the customer gets more when the software does less.
