• Establish Service Level Agreements (SLAs): Define SLAs to set expectations for issue resolution times and maintain a high level of service.

• Plan for Scalability: As your business grows, the ERP system will need to accommodate additional users, data, and possibly new modules or integrations.

Maintenance and support are not just about fixing problems; they are about enhancing and optimizing the system to deliver continuous value to your business. By investing in comprehensive post-deployment maintenance and support, you can ensure that your ERP system remains a powerful tool for business efficiency and growth.

17. Measuring the Success of Your ERP Implementation

Measuring the success of your ERP implementation is crucial to understand the return on investment (ROI) and to identify areas for further improvement. It involves evaluating the system’s impact on your business operations and whether it has met the goals and objectives set out at the beginning of the project.

Key metrics to assess the success of your ERP implementation include:
