In Appian, Start Process (a!startProcess) and Start Process Link (a!startProcessLink) are both used to initiate process models from an interface, but they differ fundamentally in user interaction and technical behavior

Summary of Usage

1. Use Start Process when you want to trigger an action (like sending an email or updating a database) without interrupting the user's current screen.
2. Use Start Process Link when the user needs to immediately complete a form or a series of steps as part of a new process.
