How did you achieve reusability via QTP?

I achieved reusability in QTP (QuickTest Professional) by creating reusable components such as function libraries and action templates. I encapsulated common tasks and frequently used functions within these libraries, allowing multiple test scripts to access them. Additionally, I employed shared object repositories to manage and reuse object definitions across different tests, which streamlined maintenance and improved efficiency. This modular approach ensured that updates could be made in one location without affecting the entire test suite.
