Business war gaming or business wargaming is an adaptation of the art of simulating moves and counter-moves in a commercial setting. Unlike military war games, or fantasy war games which can be set hundreds of years in the past, business war games are usually set in the present and are a relatively recent development, but they are growing rapidly.
The rationale for running a business war game is that it is a tool of particular value when the competitive environment is undergoing a process of change, as it allows decision makers to consider proactively how different players can react to the change, and to each other. The benefit of teams role playing competitors and developing more robust strategies is especially notable, and can be inferred from a quote such as the one below from Richard Clark, CEO of Merck and Co., who in an interview to USA Today said: "I am a strong believer in if you’re going to develop a vision or a strategic plan for the future of a company that you have to engage the organization in doing that…it can’t be just the CEO or top 10 executives sitting in a sterile conference room."".
Currently there are three schools of thought about business war game, depending on the underlying philosophy of their creators: "Business is War" war games, "Business is a Game" war games, and "Business is Business" war games. The three types have accordingly, different strengths and weaknesses, and are useful for different applications throughout business.
Sometimes abbreviated as 'BIW' war games, 'Business is War' games are a direct adaptation from the military war games, and envision competitors as the "enemy" and the goal as "victory" in a market "battle". These games are based on mathematical modeling of contestable markets, including chaos theory, random variable generation (Monte Carlo simulations), and econometric modeling of demand and supply conditions. Participants’ generated moves are fed into computer program which generates optimal solutions in the mathematical space. Not surprisingly these games come with a high price tag, and are advocated by large consulting firms which tend to work with the US military establishment.
