The manufacturing industry operates in a zone of constant pressure to maintain productivity and profitability, along with maintaining the quality of products.
Amidst the production lines, machines and workforces, there exists an unseen entity, the hidden factory, which unknowingly lingers in the manufacturing processes. This entity is the source of inefficiencies and waste, reducing productivity, impacting the bottom line and creating a false illusion of performance.
The elusive term ‘hidden factory’ describes the unseen inefficiencies and waste buried deep beneath the manufacturing processes. These hidden elements can make a significant dent in the overall productivity and profitability, adding to increased costs without adding value.
Invisible to the naked eye, this hidden factory is difficult to measure or account for, making it hard to quantify its negative impacts. However, these impacts may manifest themselves in various forms, such as schedule loss, quality loss, performance loss and availability loss.
Hidden factory production leads to higher than normal waste, lower quality of products, longer production schedules and unsatisfactory customer delivery. While it is very much a part of the manufacturing process, its activities do not add any customer value, which makes it even more important to address them.
Understanding the existence of the hidden factory and addressing its impacts is of paramount importance. It’s about more than just maintaining your bottom line.
It’s about striving for greater process improvement. By acknowledging the hidden factory, you can unveil opportunities to improve equipment ROI, experience happier customers, enhance competitiveness, and refine work processes to deliver customer value more effectively.
Understanding the Hidden Factory
The notion of the hidden factory extends beyond the abstract. It manifests in physical forms in various areas of manufacturing processes. These areas include losses in schedule, availability, performance, and quality. The existence of losses may be particularly notable in workarounds or when defects flow downstream.
You can visualize it as a process operating beside your main manufacturing processes, siphoning off resources and time but not contributing to the value-added production. This parallel factory is hidden because its undesirable outputs – rework, scrap, inefficiencies, and overtime – often go unmeasured. They blend in with the actions of the ‘real’ factory, disguising themselves as normal activities.
Key constituents of the hidden factory include:
- Workarounds: These are temporary quick-fix solutions to keep the production on schedule, which typically lead to inefficiency and quality issues.
- Rework: When defects are discovered, the product must be corrected or redone, leading to additional time and costs not accounted for in the original process.
- Scrap: Material that cannot be used in production due to defects or inefficiencies.
- Overtime: Additional hours worked to compensate for schedule loss or to fulfill customer demand.
The true cost and inefficiency of the hidden factory are even harder to measure as they are diffused through various parts of the manufacturing process. It creates a false illusion of performance while in reality, it is decreasing the fully productive time of the manufacturing process.
Recognition of these hidden factories can pave the way towards a more efficient and effective manufacturing process.
By addressing these hidden areas and eliminating waste, the organization can not just increase its throughput but also ensure customer satisfaction, improved capacity planning, enhanced competitiveness and overall, lead to greater process improvement. The first step to addressing the hidden factory, however, is to reveal its existence in the manufacturing lines.
Revealing the Hidden Factory
Concealed within the intricate workings of the manufacturing process, the hidden factory can be challenging to reveal. However, through strategic data analysis, we can expose these destructive elements and begin recapturing lost production capacity.
Here are some strategies to reveal the hidden factory:
- Accurate Production Data: The first step in revealing the hidden factory is capturing accurate production data, which includes machine downtime, scrap rates, process speeds, and more. This real-time data can be collected using sensors and industry 4.0 technologies or obtained from maintenance logs.
- Rolled Throughput Yield Analysis: This is a measure that quantifies how often a process is done right the first time. It’s calculated by considering the number of units that meet quality specifications without rework. A lower Rolled Throughput Yield (RTY) can signify a large hidden factory.
- Waste Generator Identification: Streamlining the process to identify what and where waste is being generated is essential. Tools like Pareto charts or the ‘8 wastes of lean’ are great starting points.
- Capacity Analysis: This involves measuring the amount of output that a system is capable of achieving over a specific period. Any gap between real and potential output can point to the existence of a hidden factory.
Coupled with the digital transformation, lean, and six sigma methodologies, the hidden factory lurking within the manufacturing processes can be efficiently revealed.
By understanding the impact of these elements, you can tap into the hidden factory, increase throughput and improve capacity planning while decreasing overtime.
Addressing the Hidden Factory
Upon revealing the hidden factory, the next significant action is to devise strategies and work processes aimed at reducing its impact. Curing the system from this hidden disease involves:
- Reducing Human Struggle: Minimize manual labor wherever possible and implement collaborative robots that can take over repetitive tasks.
- Making Space for Small Inefficiencies: Instead of focusing entirely on larger process issues, allocate resources to address smaller inefficiencies which can accumulate over time.
- Engaging Employees: Your workforce can be the best resource for identifying and solving hidden factory issues. They’re directly involved in daily operations and can provide valuable insights.
- Focusing on risk rather than productivity: Classify tasks based on risk factors. It might be better to slow down on some tasks to ensure quality and avoid rework.
- Investing in the system rather than new technology: New technology can be a lure but more often than not, it’s about using current systems more effectively. Investment should be made towards creating a provision for better use of existing resources.
- Encouraging Open Communication: A culture of open communication can be a boon in uncovering hidden factory elements. Feedback loops and sharing of information can often lead to discovery and solution of the hidden factory problems.
Hidden factories should not be viewed as a burden, but rather an opportunity to improve the system, eliminate waste, and increase profit. Addressing the hidden factory can improve performance and help achieve maximum value from manufacturing processes.
While uncovering and addressing inefficiencies in the ‘Hidden Factory’ can lead to significant improvements in manufacturing processes, it’s equally crucial for organizations to ensure the security and integrity of their information systems.
As manufacturing becomes more digitized and reliant on data, safeguarding this information becomes paramount. This is where standards like ISO 27001 come into play. Achieving ISO 27001 certification demonstrates a commitment to information security and brings about operational benefits, ensuring that potential risks are identified and mitigated before they can impact the manufacturing process.
The Hidden Factory in Manufacturing Processes
The hidden factory in manufacturing processes, though invisible, holds a substantial potential for improvement and cost reduction. Understanding and revealing the hidden factory can unlock untapped production capacity, improve process efficiency, and most importantly, provide maximum value to the customer.
The successful implementation of lean and six sigma practices can ensure that waste is eliminated from the manufacturing processes. This would contributively improve ROI, keep manufacturing businesses competitive in a constantly evolving industry.
In this modern age of manufacturing, we have the tools and methodologies available to expose, analyze, and mitigate the effects of the hidden factory.
Its up to us, whether we choose to let the hidden factory run unabated, gnawing away at our profitability and productivity. Or we take targeted actions to bring it under the spotlight, address its root causes and mold it into an entity that contributes towards improving manufacturing productivity rather than feasting on it.
