Top 10 ERP Implementation Mistakes to Avoid


In today's hyper-competitive business environment, companies must adopt modern systems to streamline business operations and stay ahead of the curve. ERP, or Enterprise Resource Planning, is one of the most popular software systems that helps streamline business processes and enhance organisational efficiency. However, ERP implementation is not an easy task. According to a study by ERPFocus, 60% of ERP implementation projects fail to meet their objectives. In this article, we will outline the top 10 ERP implementation mistakes to avoid to ensure a successful implementation.

Understanding ERP Implementation Mistakes

ERP implementation is the process of introducing a new enterprise software solution throughout a business, which replaces either an existing ERP system or a network of disparate systems and software applications like accounting solutions, inventory management tools, MRPs, and CRMs. This comprehensive process encompasses various activities, including planning, designing, configuring, testing, training, and rollout. ERP software solutions aim to integrate diverse business functions into a centralised system, but this transformation also introduces certain risks related to technology, people management, change management, business transformation and process management. Unfortunately, during this complex process, many organisations make mistakes that can result in ERP implementation failure.

Why do ERP Implementations Fail?

There are several reasons why ERP implementations fail, such as:

  • Poor planning and execution
  • Lack of adequate budget
  • Insufficient training and support
  • Inadequate data management
  • Resistance to change

Top 10 ERP Implementation Mistakes to Avoid

Now, let's explore the top 10 ERP implementation mistakes as well as our advice on how to avoid them:

1. Poor Planning and Execution

One of the most common mistakes in ERP implementation is poor planning and execution. Organisations need to have a clear understanding of their business processes and requirements before selecting an ERP system. Whilst many businesses choose to work with an implementation partner, who usually provides their own statement of work and project plan, this does not mean that your organisation can rely 100% on their approach. Your ERP steering committee should also have a detailed plan in place for the implementation process, including timelines, budgets, and resources internally in order to effectively manage the rollout process and make good business decisions during the planning stage.

Our Advice on Planning

Take the time to conduct a comprehensive analysis of business requirements, involve key stakeholders, and create a detailed implementation plan. Define specific goals, allocate resources effectively, and establish contingency plans to address unexpected challenges. It is also a good idea to appoint a temporary internal project manager to oversee planning and preparation for your implementation, to provide a central point of contact for all stakeholders.

2. Lack of Adequate Budget

ERP implementation can be expensive, and companies need to have a realistic budget in place. They should consider all the costs associated with the implementation, including software licences, hardware, training, and consulting fees. A good ERP Partner will provide you with a detailed breakdown of their statement of works, including granular details on budget for the various phases and tasks that will be completed during the process. You should also discuss a contingency budget with your partner to ensure that you are fully prepared for any changes to scope that may arise to align the solution to your current business processes.

Our Advice on Budget

Gain executive support by clearly communicating the costs, benefits and strategic importance of each step in the ERP implementation process. Be sure to involve end-users from the beginning, seeking their input and addressing their concerns to ensure you have a comprehensive understanding of the requirements of the system at go live. This approach also promotes a sense of ownership and encourages smooth adoption. It’s also a good idea to plan for at least 20% cost overruns on your budget to ensure that you are able to react to scope change requests quickly.

3. Insufficient Training and Support

ERP systems are complex, and employees need to be trained on how to use them effectively. Organisations should provide comprehensive training to their employees and ensure that they have ongoing support to address any issues that may arise. Neglecting proper training and change management can lead to user resistance, lack of system understanding, and errors in utilising the ERP system. Inadequate change management can also undermine the business’s transition to new processes.

Our Advice on Training

Do not underestimate the learning curve for users. Develop a comprehensive training program that addresses the specific needs of different user groups. Ensure that end-users receive adequate training on the new system's functionalities and processes. Additionally, implement a change management strategy that includes communication, coaching, and ongoing support to facilitate a smooth transition.

4. Inadequate Data Management

Data is a crucial component of any ERP system, and organisations need to ensure that their data is accurate, complete, and up-to-date. They should also have a plan in place for data migration from the existing system to the new ERP system. Mishandling data during ERP implementation can result in data integrity issues, incorrect information, and operational disruptions. Inaccurate data cleansing, incomplete data mapping, and data migration errors can compromise the system's effectiveness.

Our Advice on Data Management

Prioritise data quality by conducting a thorough data audit, cleansing and validating the data before migration. Define clear data migration procedures, including mapping, transformation, and validation steps. Regularly back up data and perform rigorous testing to ensure a seamless transfer of information. Also remember that in most cases, keeping a user licence to your old system in case you need to reference historical data is a much easier and cost effective way to transition from your old system to a new ERP. For the sake of simplicity, in most cases, a full historical data migration is not necessary. Make sure you discuss this with your implementation partner to understand the complexities of data migration and why avoiding this may result in a better outcome.

5. Resistance to Change

Resistance to change is a frequent hurdle encountered during ERP implementation. When organisations introduce a new ERP system, employees may exhibit resistance due to fear of the unknown, concerns about job security, or a reluctance to adopt new processes. Failure to address resistance can hinder the implementation process and undermine the potential benefits of the ERP system.

Our Advice on Change Management

To overcome resistance to change, companies must prioritise effective communication and employee involvement. It is crucial to clearly communicate the benefits and advantages of the new ERP system to employees specifically in relation to their role and duties. This entails explaining how the system will streamline their workflow, enhance efficiency, and ultimately contribute to their job roles and the organisation as a whole. By highlighting the positive impact on individual employees, resistance can be better managed.

6. Lack of Executive Sponsorship

Executive sponsorship is critical for the success of ERP implementation. Organisations need to have a senior executive who is responsible for the implementation process and has the authority to make decisions and allocate resources. Without strong executive support and user involvement, ERP implementation can face resistance, lack of resources, and low user adoption rates, which will impact business growth. Top-level commitment and end-user engagement are vital for successful implementation.

Our Advice on Executive Sponsorship

To ensure a successful ERP implementation, it is essential to have a senior executive who takes ownership and provides sponsorship throughout the process. This executive should have the authority to make decisions, allocate necessary resources, and drive the implementation forward. Their role is crucial in setting the direction, prioritising the implementation efforts, and ensuring alignment with the organisation's strategic goals.

7. Over-customisation

While ERP systems offer customisation options to tailor the system to a business's specific needs, it is important to strike a balance and avoid excessive customisation. Over-customisation can lead to a range of problems and challenges during and after ERP implementation. Excessive customisation can increase costs, prolong implementation timelines, and complicate system maintenance and upgrades. It can also introduce complexities that may hinder the organisation's ability to take advantage of future system enhancements or new functionalities. Therefore, companies undertaking an ERP implementation should exercise caution when considering customisation and carefully evaluate the long-term implications.

Our Advice on Customisation

To avoid over-customisation, organisations should thoroughly assess their business requirements and determine if customisation is truly necessary. It is essential to differentiate between critical business needs that require customisation and non-essential preferences that can be addressed through system configuration. By focusing on configuring the system well, and aligning business processes with out of the box functionality where possible rather than undertaking excessive customisation, companies can strike the right balance between tailoring the ERP system and ensuring its long-term viability.

8. Poor Communication

Effective communication is a critical factor in the success of ERP implementation. Insufficient or ineffective communication can lead to misunderstandings, confusion, and resistance among employees, stakeholders, and vendors. To ensure a smooth and successful implementation process, companies must prioritise clear and regular communication. In addition to internal communication, it is crucial to maintain effective communication with ERP vendors and implementation partners. Regular updates, progress reports, and collaborative discussions with these external stakeholders ensure alignment, resolve any potential issues or roadblocks, and facilitate a seamless implementation process.

Our Advice on Communication

During the implementation, organisations should establish dedicated points of contact or liaisons who can serve as communication channels between the implementation team, employees, and stakeholders. These individuals can provide updates, answer questions, and act as a bridge for effective communication.

9. Inadequate Testing

Thorough testing is a crucial aspect of ERP implementation to ensure that the system functions as intended and meets the business's requirements. Inadequate testing can lead to functional issues, data inaccuracies, and system failures, negatively impacting the overall success of the implementation. To mitigate these risks, your team must prioritise comprehensive testing throughout the implementation process.

Our Advice on Testing

Having a well-defined testing plan is essential. This is something that your implementation partner should be able to provide you early in the process to ensure your team thoroughly understands what is required ahead of time. The plan should include different types of testing, such as unit testing, integration testing, and user acceptance testing. Unit testing focuses on verifying individual components or modules of the ERP system to ensure they work correctly. Integration testing examines the interaction between different modules or interfaces to identify any potential issues. User acceptance testing involves end-users testing the system in a simulated real-world environment to ensure its usability and effectiveness.

Testing should encompass various scenarios and use cases that reflect real-life business processes. It is important to test not only the system's expected functionalities but also potential edge cases and exception scenarios. This helps uncover any gaps or flaws in the system's performance and functionality.

10. Failure to Measure Success

Measuring the success of ERP implementation is crucial for organisations to evaluate the effectiveness of the implemented system, identify areas for improvement, and ensure alignment with their goals. Unfortunately, many companies make the mistake of not establishing clear metrics and failing to regularly monitor and report on their progress.

To avoid this mistake, your ERP steering committee should define key performance indicators (KPIs) that align with their strategic objectives and reflect the desired outcomes of the ERP implementation. These KPIs can vary based on the organisation's specific goals, but commonly include metrics such as improved operational efficiency, cost savings, increased productivity, reduced error rates, or enhanced customer satisfaction.

Our Advice on Measuring Success

Once the KPIs are established, it is important to monitor and track them regularly. This can be done through data analysis, system reports, and other monitoring tools. Regularly reviewing the KPIs allows companies to identify trends, measure progress, and identify any gaps or areas requiring attention.

In addition to monitoring, organisations should establish a reporting mechanism to communicate the progress and results of the ERP implementation to key stakeholders. This can take the form of periodic reports, presentations, or dashboards that provide a snapshot of the achieved results against the defined KPIs. Reporting helps keep stakeholders informed and engaged, facilitating discussions on potential improvements and adjustments.


Implementing a cloud-based ERP system is challenging, but with proper planning, adequate training, and effective communication, organisations can leverage the software solution to streamline their operational processes, optimise asset management, and achieve better business performance.

Implementing a cloud-based ERP system also requires careful consideration and planning to avoid costly mistakes and implementation disasters. It is crucial for organisations to align the ERP implementation with their business objectives and current processes. Failure to properly plan and assess the exact costs and resources needed can lead to wasted time, effort, and money.

By avoiding common pitfalls, organisations can unlock the competitive advantages offered by ERP systems and drive their digital transformation journey.
