The divide between plans and reality can feel unbridgable.

Enterprise Resource Planning systems promise to streamline manufacturing operations - which should be a good thing. Why, then, does everyone complain about them?

Indeed, the gap between promise and reality is wide. In this article, we’ll argue that it stems from a fundamental mismatch between how ERP systems work, how software companies make money, and how manufacturing businesses actually run.

“Most ERP frustration comes from trying to make the software fit real-world manufacturing processes,” says David Berube, Principal at Durable Programming. “When the software forces you to work its way rather than your way, people get angry and efficiency drops.”

This is not to say that ERP software isn’t closely tied to a business model.

That’s a misunderstanding.

Whose Software Is It?

ERP cloud software is designed to serve the software companies, not you - they want to reduce their costs and amplify the value of their software engineering efforts. They also want a standardized interface that allow them to use less talented - and therefore cheaper - staff to implement features, even if those features do not work as well for the company in question.

In other words, ERP software is awkward because its serving the vendor first and you second.

The roots of this frustration run deep. ERP systems evolved from accounting software, building manufacturing capabilities on top of financial foundations. While this approach works well for tracking costs and inventory value, it often fails to capture the nuanced realities of shop floor operations.

“The core problem is that most ERP systems try to force manufacturing into standard templates,” notes Berube. “But real manufacturing is messy, with constant exceptions and adjustments. When the software can’t handle that flexibility, people end up fighting the system rather than using it.”

Integration issues compound these challenges. Despite vendor promises of seamless connectivity, many manufacturers struggle to connect their ERP systems with other critical business applications. The result is a patchwork of manual workarounds and duplicate data entry.

“ERP systems… extensive functionalities can be hard to navigate, especially for those with limited training,” notes Mohammad Kamal of Olavivo.

The Human Factor

The human factor also plays a major role in ERP frustration. Workers accustomed to flexible, paper-based processes often resist the rigid structure of ERP systems. Training becomes an ongoing challenge as new employees struggle to learn complex software interfaces.

Much ERP frustration stems from “bad” implementation decisions - at least, “bad” in the sense of being ill-fitting for a particular company. Companies often rush to implement “standard” ERP processes without thoroughly analyzing their unique requirements - a bit like buying clothes without trying them on. This leads to forced workflow changes that damage productivity rather than enhance it.

“Successful ERP implementations start with understanding how your business actually works,” explains Berube. “You need to map your real processes first, then configure the software to support them - not the other way around.”

“If I could change one thing, it would be … an improved user interface that reduces unnecessary clicks. Many of these systems were built decades ago, and they haven’t evolved to match the speed of today’s operation” says Georgi Petrov, CMO at AIG Marketer.

So called “modern” cloud-based ERP systems promise to reduce these frustrations - but, despite claims, they often make customization harder, not easier. The fundamental challenge remains: aligning software capabilities with manufacturing realities is easier said then done.

The path forward requires a more balanced approach to ERP implementation. Rather than forcing businesses to conform to software limitations, manufacturers need systems that can adapt to their proven workflows while still providing the benefits of integrated data and automated processes.

While ERP frustrations may never completely disappear, understanding their root causes helps manufacturers make better software decisions and implementation plans. The key is finding the right balance between standardization and flexibility - leveraging ERP benefits while preserving the unique processes that drive competitive advantage.

Ultimately, the most successful ERP implementations come from treating the software as a tool to support proven business processes rather than a rigid template that must be followed. This mindset shift, combined with careful system selection and implementation, can help manufacturers realize ERP benefits while minimizing the frustrations that too often accompany these critical business systems.

The future may bring more flexible, intelligent ERP systems that better adapt to manufacturing realities. For now, success requires careful planning, realistic expectations, and a commitment to making the software work for the business rather than the other way around.
