given up to proving we achieve and sustain that integrity level for the life time of the plant. But there
lies the rub, whilst our consultancy colleagues were becoming fat on the risk assessment bandwagon
the outputs of their labours (reams of documents) were promptly placed in a dark drawer never to be
seen again.
We must also consider functional safety planning not because there was any but because planning is
so integral as we move forward. In the 90’s and early 00’s planning was only really the ‘project
schedule’. At best verification and validation could be rolled into final testing. Assessment and audit
represented by design reviews. A quality plan may call upon an independent reviewer but that was
about that.
So what has changed? Where are we today and where should (and could) we be tomorrow?
