3. Railway obsolescence management methodology
The methodology described in the IEC 62402:2019 is perfectly suited to the railway world.
To determine the obsolescence strategy for a product or system, obsolescence risks must be assessed using a recognized evaluation method. For example, the probability and impact of obsolescence can be assessed over the life cycle. This assessment should be carried out at the initial design stage, and reviewed periodically.
If the combination of probability and impact of obsolescence is medium or high, a proactive approach should be followed – in which case there should be an obsolescence management plan to mitigate obsolescence risks.
If the combination of probability and impact of obsolescence is low, a reactive approach can...
