Legacy Systems & Digital Transformation

A Guide for Faster Evolution

"The equipment cost itself is sometimes not that significant, but the integration and support required for hundred of pieces of machinery significantly impact operating costs and complexity."

— Greg Geihsler , Technical Director, Proctor & Gamble

U.S. manufacturers are making solid headway on digitalization to make operations more efficient, sustainable, and resilient. New high-tech factories generate a lot of excitement and often steal the headlines, but most manufacturing leaders can relate better to the less flashy story of bringing digitalization to legacy operations at older facilities. Here, machines and processes are undergoing the gradual but important shift into the digital age.

Manufacturers Alliance Foundation surveyed around 200 U.S.-based manufacturing companies and spoke one-on-one with manufacturing leaders about successful strategies for legacy operations. A Guide for Faster Evolution is a follow up of Digitalization Gains, an assessment of manufacturers’ progress towards digital transformation.

While funding, security, and talent represented significant concerns, interoperability and complexity stood out as the thorniest problems manufacturers face as they advance on their digitalization and artificial intelligence journeys. Here, the best solution may not require a rip-and-replace approach but rather bridging technologies that allow manufacturers to get more out of their still-functioning legacy machines and operations. “It quickly becomes a larger conversation about how you’re managing the lifecycle of your equipment,” added Philip Vita, Technical Director at Procter & Gamble, “digital capability is just another factor in the overall decision.” 

Top Concerns About Technology Upgrades

  1. Budget constraints hindering timely upgrades
  2. Balancing security concerns with the need for technological advancements
  3. Limited availability of skilled workforce for emerging technologies
  4. Concerns about compatibility of existing systems with new technologies
  5. Managing the complexity of integrating diverse technologies

The good news — it’s not an all-or-nothing choice. The most advanced digitalization and AI tools can provide that bridge so many companies need while embracing new approaches to partnerships, customers, and ecosystems. Most (55%) are investing in continuous improvements with ongoing upgrades, and only a minority, 21%, are doing major periodic overhauls.

“I don’t think there was a strategy, and technology investments were completely decentralized. Obviously, this made it hard to have a holistic digital strategy.”

Many manufacturers are solving interoperability problems by adding an edge device on the machine layer and sending encrypted data to the cloud. But tackling legacy systems isn’t purely a hardware or software solution. Digitalizing, and often simplifying, processes are a huge step. Whether you update your process or take a “lift and shift” approach, there are many options to consider.  

Manufacturers are not adopting technology just because it’s new. Innovation must be relevant to real-world manufacturing needs, and that pace of change and adaptation varies. Manufacturing lags behind other industries in creating ecosystems to solve digitalization pain points. Survey respondents recommend partnering internal and external resources to assess the right technology for their needs.
