Actually choosing a strategy entails making decisions that explicitly cut off possibilities and options. An executive may well fear that getting those decisions wrong will wreck his or her career.
The natural reaction is to make the challenge less daunting by turning it into a problem that can be solved with tried and tested tools. That nearly always means spending weeks or even months preparing a comprehensive plan for how the company will invest in existing and new assets and capabilities in order to achieve a target—an increased share of the market, say, or a share in some new one. The plan is typically supported with detailed spreadsheets that project costs and revenue quite far into the future. By the end of the process, everyone feels a lot less scared.
This is a truly terrible way to make strategy. It may be an excellent way to cope with fear of the unknown, but fear and discomfort are an essential part of strategy making. In fact, if you are entirely comfortable with your strategy, there’s a strong chance it isn’t very good.
