Couple of thoughts on the three lessons learned from Finland:
1. Focus is good, but more important than focus is exploiting the strengths of the organizational team. If a company's organizational strengths are designing "whosits" and we focus on making "widgets", focus will bring a company down. Identifying what the organizational strengths are, ensuring that those organizational pillars are firmly in place for the journey, and leading the ship as it enters rough waters will keep the organization focused on the end goal. Simplying focusing on this or that is an easy way to lose focus and a common small business mistake.
2. Balance and rest are vital, without it a person may go strong for a year but will eventually burn out, lose focus, and throw the whole ship out of balance. That goes for the entire organization, from the top to bottom. One unbalanced or exhausted member and the entire team becomes unbalanced. The flip side is that too much balance and rest is just as unbalancing.
3. People are important, but leadership is even more important. People will follow, help, and sacrifice for leaders, and by doing so carry an organization through tough times. In contrast, people can only take others so far and when the waters get rough, they jump ship.
So if we are talking about what all successful businesses have in common, I would argue that more commonly its leaders and not people. Good people are a by-product of good leaders, and a good leader knows how to attract, retain, and reward good people. Good people then leads to great organizations, and great organizations then lead to greater rewards for everyone, including more number 2!
