The world of scaling needs a “common sense checklist"

Most scaling failures are complicated. Identifying a list of potential problems before you scale up can improve the odds of success:

• Use incentives that can scale. This applies to creating healthcare or education policy, trying to grow your startup, or just helping your community get along better.
• Make all of your decisions on the margin. Don’t be a prisoner to looking at averages, as data is always presented in averages. Instead, a marginal way is to pick the low-hanging fruit right away, then scale over marginal people, not over the million people who have already consumed it in the past.
