Design changes and part replacements were not properly shared, resulting in "unanticipated rework" during the prototyping and mass production stages.
When design flows are highly dependent on individual people, know-how is lost every time a new person is assigned to a different department, causing quality and delivery dates to fluctuate.
Furthermore, when BOMs, drawings, and specifications are scattered across departments, the confusion of "not knowing which is the latest version" slows down production, resulting in unnecessary costs and time.

With this kind of disconnect, it is not even possible to visualize how much the design department is contributing to revenue and costs, and management decisions tend to be made too late.

--Reconnecting the engineering chain and creating a system that allows design information to be shared across the company in real time is the first step in reform to achieve short delivery times and high-quality manufacturing.
