Can your business afford to lose millions due to a failed ERP implementation?

In 1999, Hershey’s ERP system failure cost the company over $100 million—a shocking example of how an unsuccessful ERP implementation can derail an entire business. And Hershey isn’t the only one. Many companies have faced similar setbacks, losing millions due to poorly executed ERP projects.

When you invest in an ERP (Enterprise Resource Planning) system, you're hoping for smoother operations, seamless data integration, and better decision-making. But what happens when things don’t go according to plan?

Unfortunately, ERP failures are more common than you might think, and the consequences can be devastating. Studies show that nearly 70% of ERP projects fail to meet expectations, leading to disrupted operations, damaged customer relationships, and costly financial losses. So, why do ERP systems fail, and more importantly, how can you avoid these costly mistakes in your own business?

In this blog, we’ll break down the major causes behind the unsuccessful implementation of ERP, backed by real-life case studies. We’ll also share strategies to help you achieve ERP success without the headaches.

What is ERP, and Why is Its Implementation Crucial?

Enterprise Resource Planning (ERP) systems are integrated software solutions that help businesses manage various functions, such as finance, HR, supply chain, POS, and customer relationship management (CRM), in one unified system. When implemented correctly, ERP systems boost efficiency, enhance reporting, and enable better decision-making across all areas of your business.

For startups and SMEs in Saudi Arabia, investing in an ERP system like HAL ERP can truly transform your operations. With real-time data access, reduced manual work, and streamlined business processes, the right ERP system can automate repetitive tasks, improve cross-departmental communication, and significantly increase operational efficiency.

With a clear understanding of ERP’s potential benefits, it's important to address why many ERP implementations fail. 

Why ERP Systems Fail

The ERP failures often stem from common causes like poor planning, unrealistic expectations, lack of funding, and insufficient training and support. High-profile ERP failures make headlines, leading to bad publicity, lawsuits, and major financial losses.

The good news is that not all ERP implementations have to fail. By understanding why past projects failed, you can avoid making the same mistakes and ensure your ERP project succeeds.

However, ERP implementation can be challenging. Let’s explore the common causes behind the unsuccessful implementation of ERP. 

Common Causes of ERP Failures & How to Avoid Them

Common Causes of ERP Failures & How to Avoid Them

ERP systems promise major improvements, but many businesses struggle during their implementation. This often results in what’s called an "unsuccessful ERP implementation." Let’s explore some of the most common causes and how you can avoid them.

Cause 1: Lack of Clear Objectives and Planning

A common cause of ERP failure is poor planning and unclear objectives. Without a defined strategy, companies often implement ERP systems that don’t align with their actual needs, leading to scope creep, cost overruns, and missed expectations.

How to Avoid It: Set clear, measurable goals before starting your ERP project. Ensure these goals align with your business strategy. Involve key stakeholders early to gather input and ensure the system fits the company’s needs and processes.

Cause 2: Underestimating the Scope of Change

Many businesses underestimate the changes needed when implementing an ERP system. These go beyond installing new software—they involve process updates, staff retraining, and workflow adjustments. If not managed well, these changes can lead to resistance and disruptions.

How to Avoid It: Recognize the full scope of changes that come with ERP implementation. Develop a comprehensive change management plan, which includes training programs, clear communication, and strong employee support to ensure a smooth transition.

Cause 3: Inadequate End-User Training and Adoption

ERP systems often fail when users aren’t adequately trained. This leads to frustration, mistakes, and underuse of the system’s capabilities.

How to Avoid It: Invest in thorough training for all users before, during, and after the system is deployed. Ensure employees know how to use the system effectively. Provide ongoing support to help users fully integrate the system into their daily tasks.

Cause 4: Choosing the Wrong ERP Vendor or Software

Selecting the wrong ERP vendor or software can result in poor performance and inefficiencies. Some companies choose systems based on cost or reputation without ensuring the software matches their specific needs.

How to Avoid It: Carefully evaluate ERP vendors and solutions. Make sure the system fits your company’s size, industry, and growth plans. Do extensive research, ask for references from similar businesses, and prioritize systems that meet your unique requirements.

Cause 5: Poor Data Migration and Integration

Data migration is one of the most complex aspects of ERP implementation. Poor data quality or incomplete migrations can cause significant errors and disruptions.

Solution: Implement a detailed data migration plan. Cleanse and validate legacy data before transferring it into the ERP system. Ensure the system integrates smoothly with other business systems to enable accurate reporting and data flow.

Cause 6: Lack of Leadership Commitment and Change Management

A lack of strong leadership can derail an ERP project. Without full support from senior management, the project may not get the resources and attention it needs.

How to Avoid It: Engage senior leadership from the beginning. They should champion the project, allocate necessary resources, and communicate the ERP system’s benefits. Keep stakeholders updated and maintain momentum with active leadership.

Cause 7: Lack of Dedicated Resources

Many ERP projects fail when companies do not allocate enough resources—in terms of time and personnel. Without dedicated resources, it’s difficult to manage the complexities of the implementation process, leading to delays and mistakes.

How to Avoid It: Allocate dedicated project teams and ensure adequate resources to support the implementation process. This ensures the system is fully supported from start to finish.

Cause 8: Inadequate Post-Implementation Support

ERP systems require continuous support after implementation to run smoothly. Without ongoing technical support, businesses face disruptions and missed opportunities for optimization.

Solution: Plan for post-implementation support. Ensure your team has access to technical help whenever needed, and schedule regular evaluations to optimize the system’s performance.

Cause 9: Overly Ambitious Timelines

Setting unrealistic timelines for ERP implementation is a common pitfall. Rushed projects lead to incomplete testing, lack of user training, and improper integration, which contribute to project failure.

How to Avoid It: Develop a realistic timeline that allows for proper planning, testing, and training. Allocate enough time for each stage of the process to ensure the implementation is done right, without cutting corners.

Cause 10: Insufficient Testing Before Go-Live

Skipping or rushing the testing phase is a critical mistake. Without thorough testing, businesses risk launching an ERP system with bugs and issues that disrupt daily operations.

How to Avoid It: Conduct extensive testing at every phase of the implementation. Perform integration tests, stress tests, and user acceptance testing to ensure the system works seamlessly before going live.

Now that we’ve explored the causes behind ERP failures, let’s take a closer look at real-world examples to better understand the consequences. 

Real-World Cases of Failed ERP Implementations

Real-World Cases of Failed ERP Implementations

To better understand the consequences of ERP failure, let’s examine a few high-profile cases that highlight the risks involved.

i) Hershey’s ERP Failure: A $100 Million Setback

In 1999, Hershey’s ERP implementation became a costly disaster. The company realized its legacy systems were at risk due to the Millennium Bug. Instead of investing heavily in addressing the issue, they opted to replace their ERP system entirely. They implemented three separate ERP solutions SAP, Siebel, and Manugistics. However, these systems proved too complex and disconnected, making it difficult for Hershey to use them effectively. Additionally, the timeline they set was unrealistic.

As a result, Hershey lost over $100 million in orders, and their stock price dropped by 8%. It took them a year to recover and finish integrating the SAP system.

Why it failed: Hershey’s failure was due to poor planning and choosing incompatible systems.

ii) Nike’s $500 Million Loss: Rushed ERP Implementation

In the early 2000s, Nike worked with i2 Technologies to implement an ERP system for demand planning. However, the system had bugs that caused major disruptions in distributing their popular product, Air Jordans. 

This resulted in a $500 million loss, including lost sales, project costs, and several lawsuits due to unfulfilled orders. Nike eventually switched to a more robust SAP ERP system in 2003.

Why it failed: Nike’s failure was caused by rushing the project and poor planning.

iii) National Grid: ERP Testing Oversight Leads to Chaos

Every complex ERP implementation requires thorough testing and proper configuration before going live. Unfortunately, National Grid skipped these crucial steps. Under pressure to meet an already delayed rollout date, the company pushed ahead with its ERP system launch amid the chaos caused by Superstorm Sandy.

The lack of proper planning and testing led to serious issues, including underpaid or overpaid employees, unprocessed vendor invoices, and failed financial reporting systems. National Grid ended up suing their SAP ERP vendor, Wipro, and reached a $75 million settlement, though it didn’t cover the full extent of their losses.

Why it failed: The failure was due to insufficient planning and a lack of testing before going live.

iv) Lidl’s ERP Disaster: Over $580 Million Down the Drain

In 2011, German grocery chain Lidl partnered with SAP to modernize its inventory management system. What was expected to be a smooth transition became a challenge due to Lidl’s unique record-keeping methods. This led to unexpected complications during implementation.

The project resulted in a loss of over $580 million and seven years of development effort. Ultimately, Lidl abandoned the SAP system and reverted to its original in-house inventory management system.

Why it failed: The failure was due to a lack of planning and not ensuring the ERP system fit their needs.

v) King Saud University’s MADAR Project: ERP Implementation Setback

King Saud University in Riyadh launched the MADAR project to develop an in-house ERP system. Despite the ambition, the project faced significant challenges, such as inadequate business process re-engineering, poor analysis of customization requirements, and insufficient involvement from both internal and external stakeholders. 

These issues led to the project’s failure, highlighting the critical need for thorough planning and stakeholder engagement in ERP implementations.

Why it failed: The failure was caused by poor planning and not involving the right people early enough.

Now that we’ve reviewed the causes and real-world case studies, let’s discuss the best practices to ensure your ERP implementation is a success.
