Top impediments to growth per Bain & Co who asked 377 executives:

1. 45% insufficient resources (people, funds, tools and time)
2. Inability to focus (too many distractions, indecisiveness)
3. Culture (risk aversion, bureaucracy, no bias for action)
4. Organizational complexity
5. Weak business plans (unclear vision, competing priorities)
6. Missing capabilities (gaps in staffing, poor organization)

These sound easy to remedy from the outside. It is when you are on the inside that they become more complex.
