In search of a ball throwing technique for bowling perfect game, the quality engineering approach was used to determine a robust technique that would not depend on the lane condition. Noise factors such as the dynamic friction coefficient of the lane which the bowler cannot control, and control factors which the bowler can control, were selected; appropriate throwing levels were found by quality engineering; and these appropriate levels were adopted as a set of basic levels. The basic levels can then be tuned on the basis of pocket and pin action heuristics to derive the optimal throwing trajectory. Strikes can be obtained by maintaining the optimal trajectory while tuning only the speed of the ball to deal with factors that the bowler cannot control, such as the dynamic friction of the lane.
