What is transient competitive advantage?
Transient competitive advantage is the view that competitive advantages now last a short time, so companies must keep building new ones while exiting old ones. Rita McGrath of Columbia Business School made the case in a 2013 Harvard Business Review article and in her book The End of Competitive Advantage. In her account, faster technology change and easier market entry shorten how long any edge holds.
Why it matters to a revenue leader
A sales advantage can last only a few years, whether it is a new service line or a territory where a rival is weak. A revenue leader who treats each one as permanent keeps funding it after it fades. Over a PE hold period, the sales plan may need to retire one advantage and build the next, and the exit story depends on showing that the next one is already growing.
Example
Fictitious numbersA commercial roofing company won share for three years with drone-based roof surveys that rivals could not match. By year four, two competitors offer the same surveys. The revenue leader shifts sellers toward a new leak-monitoring agreement and stops discounting to defend the survey business.
"Which of our current advantages will a rival match within two years, and what replaces it?"
