Recognizing and Responding to the Limitations of Legacy On-Premises ERP

The manufacturing floor is undergoing fundamental changes, and they’re coming at an increasingly fast pace. For anyone who has been running an on-premises ERP system, it’s likely that you’re beginning to understand the reasons why legacy ERP is poorly suited to the demands you face today.

(By the way, if you’re trying to deal with the demands of modern manufacturing – and the modern customer – without any ERP system, you have our sympathies and you should still read this post.)

Modern demands on manufacturing that your ERP needs to keep up with

Modern customers want personalized manufacturing

The traditional product-centric manufacturing model, where standardization is the norm and the goal is to win on cost or other traditional metrics, is quickly fading away. Rising in its place is a business model that puts the customer, and serving each customer’s unique needs, at the center of everything.

Whether you call it the servitization of manufacturing, or personalized manufacturing, or some other term, it’s clear this is the present and future of manufacturing. This change has been as drastic as it has been necessary. Whether they’re buying from Amazon or from you, people now expect to be treated in the same, personalized manner. Mass customization is replacing mass production.

Industry 4.0 is mature enough to support personalized manufacturing

Industry 4.0 has gone from buzzword to reality in what seems like a relatively short amount of time. And even though the technologies that support personalized manufacturing continue to evolve, they’ve reached a level of maturity and proven performance that should make their adoption palatable to even the most risk-averse manufacturer.

That’s why the markers of Industry 4.0 – automation, the flow of data across processes, cloud computing, advanced data analytics, the Internet of Things (IoT), artificial intelligence (AI), machine learning (ML), 3D printing and other additive manufacturing techniques, cloud ERP – are showing up in more manufacturing environments every day.

If manufacturers can’t meet expectations, competitors are ready to step in

Today, anyone can do business with any manufacturer. And because so many manufacturers are adopting the technologies, processes and practices that support personalized manufacturing, it’s entirely likely that if you can’t deliver what a customer wants, exactly as the customer wants it, they can find someone else to fulfill that request. Yes, the quality of what you produce still matters a great deal, but speed, the ability to customize, and your overall level of service are also paramount.

Why legacy ERPs can’t fulfill today’s manufacturing requirements

Legacy on-premises ERP systems were designed for a simpler, slower time.

The first ERP systems were introduced in the early 1990s, evolving out of MRP systems that were developed over the prior two decades. These systems were used almost exclusively by very large corporations, which had the mainframe computing infrastructure to run them, the IT staff to maintain them, and the money to afford it all. For perspective, the Internet did not exist commercially until 1993, and the first iPhone wasn’t sold until 2007. ERP systems were built for a computing environment that, by today’s standards, was rudimentary at best.

It’s no wonder, then, that legacy ERP systems, many created during the era of dial-up Internet access, cannot keep up with the demands of today’s ultra-fast, ultra-connected world.

The early requirements for ERP software were simple but evolved quickly, adding complexity

Dealing with the constraints of the computer systems they were running on, early instances of ERP had to keep things simple. Broadening out from the MRP software that came first, ERP software took care of a fairly narrow range of needs: resource planning, inventory management, visibility within a closed manufacturing environment.

Modest as these initial capabilities were, they were still a quantum leap from spreadsheets and other manual methods used to manage ERP needs. And yet, it didn’t take very long before people had exhausted the limits of early ERP systems, and began asking vendors for something more comprehensive. When organizations asked for more capability from ERP systems, they also got more complexity.

Two approaches to adding capabilities to an existing system, neither successful

ERP software users during the late 1980s and 1990s generally had two paths to follow if they wanted to add capabilities to their existing systems.

  1. Sometimes, as it still happens today with almost any legacy software, they would approach their existing vendor, who would develop the new capability – HR, finance, and order management, all of which intersect with ERP in meaningful ways, were popular additions – and bolt it onto the ERP system.
  2. Alternatively, users would approach a new vendor and then try to integrate the two solutions; add PeopleSoft’s Human Resource Management Systems to J.D. Edwards ERP, for example.

Unfortunately, neither approach could consistently deliver what manufacturing organizations really wanted, and still want: a comprehensive, seamlessly integrated suite of capabilities to manage every aspect of ERP. Even after the ERP software industry underwent major consolidation in the early 2000s, bringing wide-ranging capabilities under several brands (Oracle, Microsoft, and Infor absorbed many firms, including notable names like Seibel, Great Plains, Baan, JD Edwards, Peoplesoft, and Mapics), that goal went largely unrealized.

In summary, legacy on-premises ERP systems are built for a manufacturing environment that barely exists today.

Inherent limitations plaguing legacy ERP systems today

Regardless of the industry, legacy ERPs that are essentially relics of the mainframe era exhibit four traits that make them a drag on your competitiveness and profitability.

  1. Operating & maintenance costs – it should come as no surprise that the older and more complex a software system, the more it costs to operate and maintain. If your ERP is a true legacy system (a minimum of 8-10 years old), the TCO could be as much as five times more than a cloud-based ERP solution.
  2. Outdated or limited functionality – some older legacy ERP systems lack even simple reporting capabilities. They certainly don’t have the speed, user interface, or flexibility to support modern manufacturing models.
  3. Your data is in silos, if you have it at all – today, you have data coming at you from multiple angles: IoT sensors, CRM, inventory, order management, partners, and more. Legacy ERP is not built to unify all that information, which is a critical requirement for modern manufacturing.
  4. Hardware costs – on-premises software requires on-premises servers. They’re expensive to buy, expensive to maintain, and expensive to replace. So is the IT staff you need to manage them.

The Cloud ERP Solution

Cloud ERP software entered the market as a solution for outdated legacy ERPs. It addresses today’s challenges in these ways:

  1. Cost: Cloud-based ERP is SaaS. You factor it into your operating budget and pay as you go. Initial training and customization aside, it’s a predictable cost, a real virtue for most manufacturers.
  2. Scalability/flexibility: Cloud-based solutions were built in and for modern times, and modern times require flexibility. A cloud ERP reflects that requirement. Scaling and expanding into new regions is an intended use case.
  3. Accessibility: Cloud ERP is built for mobility. With a password and a smartphone, your people can access the system, and live data, from pretty much anywhere in the world. And even within your walls, mobile offers a benefit: manufacturing staff aren’t always comfortable with computers, but they know how to use an app on a smartphone. That comfort level enhances adoption.
  4. Security: With any ERP system, your data security needs are going to change. As you amass more (and more sensitive) information in your system, it becomes more valuable to you. But it also becomes a more desirable target for hackers. Do you have the expertise and money to erect more effective defenses? With a cloud based solution, the vendor will take care of the security of the infrastructure and share the burden of securing your system.
  5. Speed: We assume you’re in a hurry, because the need for a modern ERP that’s up to the demands of today’s manufacturing is pretty urgent. If you feel that urgency, and want to be up and running as quickly as possible, cloud is the way to go.
  6. Innovation: Without a legacy system weighing them down, cloud ERP solutions can innovate faster and adapt to new circumstances.

What about legacy ERPs that have added a cloud feature to their system?

Some vendors have responded to the growing call for cloud-based ERP by adapting their non-cloud solution to the cloud environment. Often referred to as “cloud washing,” this approach almost always yields a compromised solution. Why? Because applications built for the cloud are built to support mobility; provide ongoing, seamless upgrades; scale on request; and otherwise take advantage of the cloud environment in ways that migrated solutions can’t.

In short, if you choose cloud-based, make sure it’s also cloud-native.
