Lean thinking—for example, lean manufacturing—has a concept called pull.
pull: An arrangement in which nothing is done simply means that nothing is done in product creation or delivery until the customer (including internal customers in the design and manufacturing process) expresses a need or a demand for the product or for the intermediate “deliverable” from the downstream process.
Product-market fit can be thought of as massive pull.
Pull has two primary characteristics:
Combined with lean’s concept of flow, pull means that not only is the final product not overproduced, but neither are all intermediate parts, so that from design to delivery, a product flows from raw materials to the customer’s hand without waste: no wasted activity, time, or materials.
Product-market fit can be thought of as pull on a large scale. So many customers are demanding your product (and product features), that a clear market signal has been sent saying your product is needed. Marc Andreessen, when first describing the concept, used the term pull without referencing lean: “the market pulls product out of the startup.”3
