Published: Wednesday, August 12, 2020 - 11:01 According to the late quality guru Armand V. Feigenbaum, the hidden factory accounts for anywhere from 20 percent to 40 percent of an organization’s total capacity. Feigenbaum called the hidden factory, “that part of your organization that exists to do bad work—not because you want to do bad work, but because the whole process is such that you are driven into it.” In essence, the hidden factory are those undocumented processes that work against quality and efficiency, creating invisible roadblocks to strategic goals while driving up costs. Most troubling is the fact that the problems associated with the hidden factory go far beyond traditional quality costs. In this article, we look at how these hidden processes affect manufacturing organizations, and how they can shine a light on unseen sources of variation and inefficiency. You don’t have to look far to start noticing the ways that hidden processes create unplanned problems in the manufacturing environment. Examples include: The costs of the hidden factory show up in many different places, including traditional quality costs such as: Although these are the more obvious costs, there are many more that are less easily measured. Examples include the cost of inefficiency, as well as the cost of not being able to capitalize on new opportunities due to time and resource constraints. According to the American Society for Quality (ASQ), the hidden factory can also result in misleading numbers that increase metrics like work in progress, cycle time, and setup time. Not accounting for error rates can also lead to flawed productivity metrics, making it appear that the plant is running well, when in reality hidden problems are getting worse. Whole industries are devoted to helping manufacturers mitigate the effects of the hidden factory. Industry 4.0 technologies in particular are helping companies make huge leaps in efficiency and reliability with advanced tools like artificial intelligence (AI) and the internet of things (IoT). Other digital transformation initiatives that leverage quality software can also reduce lag time in reporting, while also helping manufacturers get closer to the source of defects. Mobile layered process audits (LPAs) are one example, allowing for quick daily checks to identify variation that causes downstream defects. LPAs and activities like gemba walks get leaders onto the plant floor, where they can look for hidden inefficiencies by asking questions, challenging the status quo, and integrating lessons from other plants. The costs of the hidden factory run wide and deep in manufacturing organizations today, which may total billions of dollars just for the largest automotive and aerospace suppliers, even before we consider other manufacturers. Rooting out these processes take time, and there are no easy answers. Digital transformation tools are helping companies uncover and correct inefficiencies in the process, and helping to increase awareness of the source of defects while fostering communication and sharing of ideas.

Rooting out invisible roadblocks to strategic goals
Examples of the hidden factory at work
• Having multiple versions of specifications, which increases the chances of using an outdated version while increasing the time it takes to update the right one
• Operators reworking parts at their station or taking extra steps that others don’t know about, which causes problems when that operator is away from work or leaves
• Line supervisors speeding up cycle time to catch up when they’re behind, not realizing it’s causing hidden part damage
• Sorting mix-ups that allow defective products to reach the customer
• Lag time in reporting quality data that allows problems to get worse
• Making it difficult for people to share ideas and improvements due to excessive red tape
• Operators not carrying out preventive maintenance on machines, which leads to hidden part damage and future machine failureHidden factory costs to consider
• Scrap and rework: According to the American Productivity & Quality Center (APQC), the cost of scrap and rework alone totals up to 2.2 percent of sales for organizations today.
• Customer complaints and warranty costs: Although product design failures are typically more expensive than production defects, either can lead to a recall resulting in millions (or more) in costs.
• Corrective action costs: If the customer has to stop the line while you bring in people to sort parts, you could be looking at $10,000 a minute.Using digital transformation to tackle the hidden factory
