Conclusions
§
A “maintain” or “evolution” strategy for your SIS requires a
structured review and should form a key part of your overall asset
management business philosophy
§
Once all implications have been addressed and a strategy agreed,
then implementation should be in accordance with IEC 61511
principles
§
By doing so, your operational strategy is understood and endorsed
by all relevant stakeholders and is much more preferable than
reactive management i.e. fire-fighting the effects of obsolescence
and the potential for failure on demand.
§
A proactive functional safety management approach should be in
place and be seen as a senior management requirement for
development and implementation, regardless of the strategy to be
applied
