Key Takeaways:

  • The automotive industry spearheaded EDI as a way to address the inefficiencies of paper-based processes and support just-in-time manufacturing.
  • Integrating EDIs with APIs allowed previously unprecedented real-time access to data.
  • Transitioning to a cloud-based EDI solution eliminates the need for on-prem infrastructure and improves security measures.

“EDI was e-commerce before e-commerce was e-commerce.” Think about that for a minute. That quote represents an interesting perspective and comes from Co-Founder and President of Remedi, Brad Loetz. It highlights how the history of EDI really matters to modern business. 

EDI originated in the automotive industry in the 1960s and resulted in improved communication between manufacturers and suppliers. As protocols evolved and improved, EDI became the universal standard. How we implement EDI has kept pace with technology advances, such as the emergence of cloud-based EDI solutions and ability to integrate with APIs.

Brad Loetz quote, EDI was e-commerce before e-commerce was e-commerce.

The Birth of EDI in the Automotive Industry

"EDI started even longer than 30 years ago in the automotive industry to pull raw material components to the production line by a lot of the auto industries." 

This insight highlights the crucial role that EDI had in transforming legacy automotive manufacturing. As the demand for cars grew, the typical reliance on paper documents and manual processes just couldn’t keep pace. Traditional methods were not only slow but also error prone. In response, major automotive companies began using EDI to streamline their operations.

The Problem: Just-in-Time Manufacturing

In the 1970s, automotive manufacturers needed large inventory to be able to meet their production needs. However, holding excess inventory can be risky from a financial standpoint given all of the capital tied up to maintain high inventory levels. The demand for vehicles grew as Americans moved away from the one-car-per family norm of previous decades, and inventory management became more complex for automakers.

The cost implications of excess inventory increased overhead costs for automakers because they needed more warehouse space to store large quantities of parts and materials. The move to just-in-time manufacturing required precise coordination with suppliers. Manufacturers needed specific materials at very precise times—which increased the need for more efficient communication. EDI solved this problem.

The Solution: Early EDI

Early EDI systems came about as a result of major automotive manufacturers and their suppliers working together to create standardized electronic formats after recognizing the need for faster and more reliable communication. 

Early EDI systems used dedicated communication networks to transmit electronic versions of important business documents such as purchase orders, invoices, and shipping notices. Initial EDI protocols were limited to basic standards for data transmission primarily focused on document formatting. Due to a lack of widespread standardization across the industry, companies encountered difficulties at times when exchanging data with suppliers and customers. 

Automotive manufacturers experienced significant benefits from implementing early EDI systems. They were able to reduce their inventory costs because EDI communication helped facilitate just-in-time delivery of materials.

The Evolution of EDI Systems

From On-Premise to Cloud

The transition from maintaining EDI solutions on-premise to hosting them in the cloud was a gradual evolution. In the early years of EDI history, EDI systems were designed for specific tasks. They could exchange data but had limited functionality beyond that. The upkeep was pretty significant too. The systems had high maintenance requirements and needed frequent updates just to stay operational. 

The need businesses had for more efficient operations gave rise to integrated solutions and EDI began to merge with Enterprise Application Integration (EAI). The integrated solutions provided more expanded capabilities, and this allowed businesses to automate workflows and better manage supply chain integration.

EDI Technical Comparison 1970s - Present
Feature 1970s EDI Modern EDI
Deployment On-premise Cloud/Hybrid
Communication Dial-up/VAN Internet/API
Data Format Limited standards Multiple formats
Integration Isolated system Fully integrated
Real-time Capability No Yes

Modern cloud-based solutions lead to Integration Platform as a Service (iPaaS). A huge benefit of iPaaS was that it eliminated the need for extensive on-prem infrastructure. Overall, cloud deployment offers numerous benefits, including scalability and reduced costs. With access to the cloud, businesses can scale their EDI capabilities as their business grows, and they can achieve that with lower upfront investment costs and reduced maintenance costs. Additional benefits include accessibility and enhanced security. Cloud providers can offer advanced security measures that would be difficult for single organizations to implement.

Despite the benefits of modern cloud-based solutions, there are challenges to consider. The cloud has many benefits, but being locked into a single cloud provider might be too restrictive for your business. Data privacy concerns will always be a consideration any time you store sensitive information in the cloud. 

The API Revolution

Brad Loetz quote, today, being able to integrate fully into apis and provide real-time data has become the cost of entry

Before the emergence of APIs, EDI relied on batch processing. With that came increased latency. APIs enabled real-time data exchange and more flexibility when integrating individual systems as APIs can support a much wider range of data types than standardized EDI formats. APIs also allowed trading partners direct access to each other’s data for the first time, improving B2B communication as a result.

EDI Meets API

EDI and APIs are really complementary technologies. Integrating EDI with APIs allows companies to maintain compliance by using EDI standards but also achieve faster and more flexible integrations that only APIs can achieve. APIs enable real-time updates, which is important for information like the current inventory levels or exact location of shipments in transit. All this represents a major positive shift in EDI evolution.

Modern systems integrate EDIs and APIs with ease through multiple approaches. Middleware allows EDI messages to be converted into API calls. API gateways act as intermediaries, allowing organizations to access EDI data via API calls if they prefer. Lastly, cloud-based solutions make it easy for businesses to take advantage of APIs since cloud-based platforms offer native support for API integrations.

Conclusion

EDI has increased in significance from its origins in the automotive industry. It’s kept pace with technological changes, including digital transformation. It works in tandem with cloud solutions and API integrations, developing value well beyond streamlined operations. The integration of EDI and APIs will continue to shape the future of EDI and drive innovations grounded in leveraging real-time data.
