Time to volume is a marketing metric that measures the time it takes for a new product to go from concept to launch and reach a significant level of sales or usage. Also possibly used as time to scale. It is similar to the time to market metric, which measures the average time it takes for products, services, and innovations to go from concept to launch. However, time to volume is intended to exclude limited launches that only reach a small number of customers, as well as products that never achieve a significant level of commercial success. The definition of commercial relevance may vary depending on the size of the organization, but it typically refers to revenue, units sold, transactions, or number of service subscribers. By tracking time to volume, organizations can measure the efficiency and effectiveness of their product development and launch processes.
