Macroeconomic (related to the big aspects of an economy, such as inflation, economic growth, recession, and levels of employment) factors are major forces that impact not just your organization, but also your competitors and your marketplace. They may impact other markets, the country, and sometimes the world economy. While you as a team or organization cannot change or control these things, you can seek to understand them and create strategies that fit in with them.
Many other factors are within your sphere of influence, and when you control them, you can set the agenda. When you control enough factors in your environment, you become the market leader and set the standards for the whole industry; if, for example, you decide to reduce your prices, your competitors are forced to reduce theirs.
Large organizations can exert huge control--even dictating government policy--but even if you cannot aspire to this level of power, you should attempt to implement strategies that give you as much control as possible. The more control you have, the fewer surprises you'll encounter and the more likely you are to survive in the longer term.
ACTION POINT: Set the agenda by understanding the factors that are within your sphere of influence.
