The first thing is not to confuse 'a module exists' with 'my project is a fit'. For DHL OCA, you need to check the real version, how well it is maintained, what the flow actually covers, and how much adjustment your operation will need before it reaches production.
What to check first
- Whether there is a usable branch for the version you are running.
- Which part of the DHL flow it actually covers.
- How it handles errors, cancellations, and logs.
- How much extra work the project will require.
When it usually fits
It usually fits when the flow is fairly standard, the project accepts OCA as its foundation, and the company understands that the value is in the implementation and tuning work, not just in installing a repo.
