Guess and guess again
One of the difficult tasks of management is identifying when a strategy needs to change. While managements use brainstorming and other techniques, which rely on the wisdom of crowds (the notion that two or more heads are better than one), in strategy development, they often fail to regularly re-assess the various underlying economic and market assumptions on which the strategy was based.
The assumptions underlying a strategy are guesses about what market and competitive conditions will be during the relevant period. Assumptions about current actual conditions can be improved through market and competitive research, but future conditions cannot be known in advance and therefore assumptions about them are in reality guesses.
Recent research, reported on by The Economist, suggests that the wisdom-of-crowds notion may also work at the individual level. The average of two guesses made by an individual at two different times was more accurate than either of their separate guesses, although not as accurate as the average of guesses made by multiple individuals. [i] Multiple people making multiple guesses over time might also improve the accuracy of their composite guesses.
How can owner/CEOs employ these concepts to improve their business performance?
- Conduct more frequent reviews of the key assumptions underlying strategies
- Expand the set of associates who participate in the development of key assumptions
- Document and average the arrays of estimates underlying key assumptions at each review and over time
- Adopt a rolling forecasting and strategy tweaking process versus the traditional fixed annual operating plan
The objective of this process is to detect likely market
changes more quickly and accurately and therefore improve the
organization’s ability to respond to those changes on a timely basis.
