A common process for developing customizations with update sets involves moving changes from development, to test, to production instances.

1. Create an update set on the development instance.
2. Make customizations and changes on the development instance.
3. Mark the update set as Complete.
4. Log in to the test instance and retrieve the completed update set from the development instance.
5. Commit the update set on the test instance, and test customizations thoroughly.
6. If the update set has problems in the test instance, repeat steps 1 - 5 to develop the fix on the development instance with another update set.
7. Log in to the production instance and retrieve the completed update set from the development instance. If the update set required a fix, retrieve both update sets.
8. Commit the update set on production. If the update set required a fix, commit both update sets in the order they were made.

If your development environment consists of only two instances, you can combine your development and testing instances into a single staging instance.

1. Create an update set on the staging instance.
2. Make customizations and changes on the staging instance.
3. Mark the update set as Complete.
4. Test customizations thoroughly on the staging instance.
5. If the update set has problems, repeat steps 1 - 4 to develop the fix on the staging instance with another update set.
6. Log in to the production instance and retrieve the completed update set from the staging instance. If the update set required a fix, retrieve both update sets.
7. Commit the update set on production. If the update set required a fix, commit both update sets in the order they were made.
