Supply chain uncertainties are dynamic and can change week to week, month to month.

The supply chain crunch has turned the once-staid world of manufacturing and industrials upside down. The imbalance is so severe that consumers are feeling the pain, as prices of raw materials and goods are thrown out of whack. Debates about inflationary pressures are raging. What more could go wrong? Well, a lot. Especially if the grease that makes the wheels turn starts drying out.
That lubricant is trust.

So far, the world has had to deal with the supply and demand imbalance of physical goods. It has been painful, no doubt. But as that’s persisted, with few long-term solutions in sight, the assurances that keep businesses going have also started running low. This matters because trust plays an unquantifiable but critical role in the codependency between manufacturers and several tiers of suppliers.

Without it, the commitment on receipt and delivery of products, parts and payments weakens. That uncertainty cripples businesses, raises costs, and decreases productivity and efficiency. Around one-third of alliances fail due to “a lack of trust among trading partners,” a study on designing and managing supply chains from the 1990s showed.

In supply chain literature, trust is broadly defined as a “firm’s belief that another company will perform actions that will result in positive outcomes for the firm” and that the other business won’t take “unexpected actions that result in negative” results. Measuring it is challenging, but there are proxies, such as surveys of business sentiment, managers and suppliers.

The trouble right now is everything is a moving target. Firms aren’t actively taking actions to hurt other companies but are protecting themselves from the constantly evolving shortages and glitches. The supply chain uncertainties are dynamic, Chief Executive Officer Mark Smucker of food-products maker J.M. Smucker Co. said in a recent earnings call. Challenges, he said, can “change week to week, month to month; it could be an ingredient or a packaging component; at one point, it could be some isolated labor challenges in a particular geography.” Smucker concluded that this dynamic would continue for the foreseeable future.

The case of Toyota Motor Corp. shows how to do this well. After years of making their system natural disaster-proof and mastering the art of just-in-time manufacturing, the company started holding more inventory early in the pandemic. It has maintained clear communication and information exchanges with suppliers through its “rescue” system. Toyota has also engaged with dealers in real time, adjusting supply of its cars in parts the U.S. This has helped ward off severe issues that other automakers have faced.

Toyota, though, is largely an outlier. For most, these changes tend to constrain business and muddy the picture for orders. Despite high demand, manufacturers’ sentiment is deteriorating, as in the case of large Japanese companies. This leads to lower future capital spending. The uncertainty creates issues for balance sheets. Suppliers often engage in short-term financing and the protracted pressures we’re seeing affect repayment, delivery and credit availability that lands them in a painful cycle.

Taken together, these snafus start looking like all the trappings of relationships with a trust deficit. As one study put it, “A lack of trust among trading partners often creates a condition where every transaction has to be scrutinized and verified.” That increases costs to unacceptably high levels, and productivity, efficiency and effectiveness are lost. The “cornerstones of supply chain goals” are compromised.

One way to alleviate the pressures, experts say, is by pushing managers to get more deeply involved in relationships with suppliers, and making a habit of communicating and exchanging information – kind of like Toyota did. The sooner companies start acknowledging a growing trust gap, the quicker they’ll start to find solutions. Until then, supply chains will remain strained.
