In his Contemporary Strategy Analysis, 6th edition, Robert M. Grant writes:
We must also recognize the nature of strategic analysis. Unlike many of the analytical techniques in accounting, finance, market research, or production management, strategy analysis does not generate solutions to problems. It does not yield rules, algorithms, or formulae that tell us the optimal strategy to adopt. The strategic questions that companies face (like those that we face in our own careers and lives) are simply too complex to be programmed.
The purpose of strategy analysis is not to provide answers but to help us understand the issues.
