Hi Gigazelle,
When we write the statement of work, we mention all our deliverables.
1. The working system with code is the first and obvious deliverable.
2. Technical design document
3. Training document, if any
4. Requirements document of what events to capture.
5. The JS code to be inserted on the web pages
Typically these are the items that we seek feedback and signoff from client.
You are right in that it might vary with the requirements, but there could be a set of typical deliverables.
Thanks,
Rama.
