You are planning to outsource the implementation of a new LoRaWAN w of the service provider performing the implementation in all cases?

• A. Proof of concept
• B. Ongoing free support
• C. Ongoing paid support
• D. Effective documentation

Answer: D

Explanation:
* Outsourcing Knowledge Transfer: When outsourcing implementation, the service provider has firsthand knowledge of system setup and configuration. Clear documentation ensures this knowledge remains accessible to you after the project is complete.
* Ongoing Support: While paid/free support options influence long-term maintenance, they won't substitute missing documentation about the specific setup.
* Reducing Future Vendor Reliance: Detailed documentation helps mitigate over-reliance on the service provider for minor changes and troubleshooting, giving you more long-term autonomy.
* Proof of Concept: A POC typically happens before outsourcing, and focuses on validating the solution's feasibility, not ensuring smooth knowledge transfer thereafter.
