Many companies pursue a product development strategy that provides a product (or service) which meets customer needs sooner (rather than later), and then makes adjustments after the product has been fielded.
Pursuing this approach means accepting the associated risks. What if a critical to quality or critical to reliability characteristic fails to meet customer needs? A product could fail miserably by eliminating important product development work scope and accelerating time-to-market. By the time an adjustment or “pivot” can be made it may be too late, or too costly to correct.
