Final answer:
One method that an RTE can use to reduce the risk of a feature associated with new technology is to conduct a technology spike or spike solution.
Step-by-step explanation:
When a release train engineer (RTE) notices a risky feature due to new technology, one method to reduce this risk is to conduct a technology spike or spike solution. A technology spike involves a short period of time where the engineering team investigates and explores the new technology or feature in order to gather more information and validate its feasibility. By doing so, the RTE and the teams can better understand the risks involved and make informed decisions on how to proceed.
