If you are not convinced, simply look at the value of materials in your typical buffer-stock locations, as well as the costs of how that space and content needs to be managed, complexi- ties of revision control, first-in/first-out man- agement, and how product quality deterio- rates with additional handling and the gather- ing of dust. Also consider the delay in feedback should any prior process or material that has been used end up contributing to defects. is creates performing very significant re-work overhead without notice. Balancing costs of shi work vs. asset utilization has always been approached through the simplification of seg- regation without really thinking through the associated consequences and difficulties. is waste becomes more significant today as we embrace the need for efficiencies in low-vol- ume/high-mix environments where such hid- den losses, once tolerable, are now crippling the business. Supporting the Change is need for change in perspective is being supported by advances in manufacturing tech- nology. We are already familiar with the inte- gration of manual, automated, and semi-auto- mated operations, such as the use of cobots and production stations where data from tools and measurement devices is automatically col- lected. Digital integration across manufactur- ing has become a reality, requiring an end- to-end approach that does not discriminate among people, automation, and AI. ere is a required confidence in deciding how to bring separated manufacturing opera- tions together—those that have been perceived to work with different technologies or simply exist on a different level of an ERP bill of mate- rials (BOM). Today, this is much easier to real- ize. Information in the right digital format fuels changes that go far beyond the simple auto- mation of manual processes. e use of CAD data, digital product models, digital twins—or whatever the buzzword of the day is—now lev- els the playing field in terms of manufacturing operation data preparation, work assignment, operational visibility, control, and coordina- tion across all production stations. is could be people-driven, automated, or somewhere in between. Let's break it down. Prepare the Relevant Production Information e first step in getting a production work- order going is to prepare the relevant prod- uct information. is comes mainly from design and the BOM. Traditionally, engineer- ing makes the key decision as to which produc- tion configuration will be used. en, depend- ing on the chosen configuration capabilities, the product data is divided up among the sep- arate engineering teams. e assignment is then fixed, as each engineering team prepares their data for either machine programming or manual assembly. is process involves a great deal of manual data manipulation and very lit- tle opportunity for flexibility. Data must be combined, separated, and converted into the various formats required for each produc- tion station. is oen requires bespoke data formatting to depend on the machine ven- dor, or documentation tools that create draw- ings and work instructions for operators. Each team independently assesses the most efficient sequence of work. is leads to unbalanced production rates and sub-assembly storage requirements. You then need a very significant amount of work, including depending on spe- cialist knowledge within each team. How a Smart Factory Differs Achieving the same result in a Smart factory is significantly different. All production oper- ations are driven by information that comes from the design digitally, potentially com-
