4.3 What is an RPA Tool?
An RPA tool is a software platform used to create and manage automation bots. It provides a visual environment where users or developers can design workflow steps, connect to applications, read data, make decisions, perform actions and generate reports.
| RPA Tool Function | Explanation | Example |
|---|---|---|
| Workflow Design | Build automation logic using visual steps. | Drag-and-drop activities |
| Bot Execution | Run automation steps automatically. | Open Excel, copy data, update ERP |
| Orchestration | Schedule, monitor and manage bots centrally. | Run bot every day at 8 AM |
| Integration | Connect to applications, databases, email and APIs. | Read email attachment and update system |
| Analytics | Track bot performance and success rates. | Dashboard showing completed transactions |
4.4 Common Components of RPA Platforms
Process Designer
