In 1973, many companies would have given their eyeteeth for having been as clear-sighted as Shell had been. The Organisation of the Petroleum Exporting Countries had scaled back oil production which resulted in skyrocketing oil prices and plunged the global economy into recession. Shell alone was not surprised by this incident which entered the world’s history books as the “oil price shock”. If, similar to Shell, your business wants to avoid nasty surprises, a systematic look into possible future challenges and issues has become more necessary than ever.
