Amberger Products competes in consumer electronics where there is a high level of market and technological uncertainty. To address these challenges, Amberger Products does not commit itself to a particular product design or features early on; instead, it is geared to quickly and inexpensively assess if it has succeeded or failed with a design or feature, learn from its past, regroup and try again quickly. The option that Amberger Products uses is called a $\_\_\_\_\_\_\_\_$ option.
