Lean Digital Thread: Achieving Supply Chain Resilience

In this column I’d like to address the challenges manufacturers have been facing due to the semiconductor chip shortage that began in late 2020 because of the COVID-19 pandemic, as well as ways to mitigate those challenges.

The shortage of semiconductor components emerged during a hypergrowth of demand for semiconductor chips. To emphasize the magnitude of the hypergrowth, the global semiconductor market is projected to grow from $452.2 billion in 2021 to $803.1 billion in 2028—almost 78% in just seven years1, or an average of 8.5% annually. The combination of this growth in demand and the shortage of semiconductor chips poses a great challenge for the entire electronics industry and for manufacturers, particularly.

A 2020 Deloitte survey2 showed that almost all manufacturers have encountered delays in semiconductor component supply as well as other critical issues such as poor component quality, order cancellations, and part substitution. These significantly impact manufacturers’ ability to supply products to customers on time, while maintaining quality and remaining within budget.

Keys for Building Supply Chain Resilience
According to the Deloitte survey, there are five key considerations in building supply chain resilience. These considerations include supply chain configuration and control, visibility into the supply chain, digitalization of supply networks, collaboration with the supply chain, and supply chain flexibility. I will cover each of these considerations in this article.

1. Supply chain configuration and control
In the Deloitte survey, 85% of the respondents indicated that analyzing critical dependencies in the supply chain is important to their business. Manufacturers need to be aware, now more than ever, of all critical aspects in the supply chain that might affect their ability to deliver their products to their customers. To respond effectively to emerging issues, manufacturers need to consider dual or multiple sourcing for critical components, maintain both local and offshore suppliers in order to cope with regional risks, take the supply risks into consideration in their make-or-buy-decisions, be aware of the resilience of production, and more.

Another aspect that manufacturers learned during the crisis is that bigger suppliers are not necessarily the most critical. Sometimes the least expensive and almost trivial component might become the bottleneck in the supply chain and eventually affect their ability to produce their goods on time.

Building a configurable supply chain with redundancy for all critical components presents an IT challenge for the manufacturer. To address that challenge, manufacturers must digitalize their supply chains and manage risk regarding each and every supplier.

2. Visibility into the supply chain
To achieve supply chain resilience, it is important for the manufacturers to have visibility into the supply chain. During PCB design, it can assist them in identifying components that are currently in low supply or might be in low supply during the project lifecycle and thus cause delays, reduced order quantity, order cancellation, or create a need for replacement components which would mean redesigning the PCB and redoing the NPI. The main objective is to identify these risks as early as possible in the process and turn these insights into actions that will, in turn, mitigate or eliminate supply chain risks.

3. Digitalization of supply networks
Digitalization and extending the digital thread throughout the supply chain is key to building supply chain resilience. With the new trend of cloudification in the industry and the emergence of cloud solutions, there is a great opportunity to break the silos of information in the designing organization and enable analysis of PCB supply chain risks during the design stage. This type of digitalization allows the PCB designer to get immediate feedback about the ability to manufacture the design and could include a supply chain analysis that would indicate any possible risk with any component used in the design as part of the design-for-manufacturing (DFM) analysis. This kind of cloud solution could automatically offer all possible alternatives to mitigate problems in the component supply. The value of this kind of cloud solution is that supply-related decisions would be taken during the product design stage, mitigating the risks of delays in component supply that lead to cancellations or reduced order quantity.

4. Collaboration with the supply chain
The digitalization described in the previous section could be further leveraged to gain full collaboration across the supply chain. From an IT perspective, it would be almost as if the supply chain was part of the design organization. This would enable automation and AI engines that could fully harmonize the design stage with the supply chain and would minimize risk in the supply chain, thus achieving a resilient supply chain.

5. Supply chain flexibility
To mitigate the various supply chain risks, supply chain flexibility is required. Risks include geopolitical tensions, protectionist tariffs, part unavailability, pandemic-related restrictions, and more. Given the risks, it is impossible to reach supply chain resilience without flexibility. This flexibility requires building a supply chain that allows redundancy in components and resource suppliers, while taking all the risks into consideration. Flexibility is key to managing a network of suppliers, being able to operationally route orders and automatically respond to any emerging issue that might affect the supply of components and resources.

Lean Digital Thread: (Pro)curing the Supply Chain Virus


Turn on the news and you’re likely to see images of something that was never considered newsworthy in the past—shipping containers. In fact, the entire supply chain has suddenly become big news due to the ongoing, severe global backlog that is preventing consumers from getting the goods they need on a timely basis. It’s a true global crisis. Since the supply chain crisis coincided with, and was hugely exacerbated by, the COVID-19 pandemic, many expect that it will be resolved when the pandemic recedes. However, that is not necessarily the case. Some major changes, such as increased demand (especially for electronics) and labor shortages, are likely to continue for many years into the future, becoming the new post-pandemic normal.

Lean Digital Thread: Why is Everyone Suddenly Interested in Supply Chain?


Prior to the global pandemic, most people didn’t give the supply chain much thought. There was no reason to—consumers had become accustomed to simply clicking on an item on a website, and it would magically arrive on their doorstep the next day. What difference did it make how it got there and where its components were produced as long as everything was running smoothly? That reality has changed drastically in the past year and a half since the onset of the pandemic. Suddenly, it seems like there is a backlog of several months on every item, from cars to washing machines to books; the supply chain has become the headline news in leading publications.
