Product discovery is a process that helps companies ensure they create useful products, not just usable ones. It involves making better decisions by aligning technical and business teams to adapt quickly to changing markets. The process answers questions about why a product is being created, who will use and be impacted by it, how users' behaviors may change, and what deliverables like software features and activities can support desired impacts. An example is a laundry services company that wants an economic solution within 3 months to reduce costs by 20% and increase business by 10% by addressing issues with how field employees currently wait for and find work.
