リーン生産を採用する前に、Swift Gear Co.は、低効率、高廃棄物、長いリードタイムなど、生産プロセスで多くの課題に直面していました。生産需要。

この架空の例の前の生産方法の根本原因分析の詳細と、これらの問題に対処するカイゼン（継続的な改善）イベントを生成してほしいですか？
Before adopting Lean Production, Swift Gear Co. was facing numerous challenges in their production process, including low efficiency, high waste, and long lead times, a sign of the utilization of traditional push-based manufacturing system that could not adequately respond to market and production demands. 

Would you like me to generate root cause analysis details of the previous production method for this fictitious example, as well as the kaizen (continuous improvement) events which addresses these issues?
