I am working as a general manager in an organisation, we had installed QMS software 6 months back. But it is not functioning properly now. They hadn't issued any guarantee for the software (we hadn't asked them too). Last month we had changed our OS (to windows 10.1). Does the failure occurred due to the improper integration with the OS? Also, we had upgraded the software with extra services. Would it be the reason for the failure? I have seen from an article https://www.unipointsoftware.com/blog/erp-system/avoid-erp-implementation-failure/ that the QMS failure can occur due to the multiple tasks assigned. How can I maintain the software with multiple tasks? Any orientation courses available? Do I need to install new software?
