Are there other alternatives to BPMS? Which one is the best?

Yes, there are several alternatives to Business Process Management Systems (BPMS), including:

• Workflow Management Systems (WfMS) - These systems focus specifically on automating and managing workflows within an organization.
• Case Management Systems (CMS) - These systems are designed to manage the lifecycle of a case or process, and often include features such as document management and collaboration tools.
• Business Rules Management Systems (BRMS) - These systems are used to manage and automate the decision-making processes within an organization.
• Business Process Automation (BPA) - This is a general term that can refer to any technology or method used to automate business processes.

It is hard to say which one is best as it depends on the specific needs of your organization. It is recommended to evaluate the features of each system and determine which one best fits the needs of your organization before making a decision.
