Ah, I wrote a long answer and the system crashed...
Basically as far as I understand it, the number of plans is used as part of the audit hours / days calculation. But I know of nobody who actually leads HACCP teams who understands what they're asking for.
I can think of a site I worked at where the answer could be 2-6 depending on how you interpret the question and as most sites who have anything apart from some really unrelated but not complex processes, most people use modular plans and most sites will have divergence and convergence at different points. Does that make it the same or a different plan? It's a non sensical question asked by someone who has never worked on HACCP IMO.
The question, is as I understand it, a CB one which only matters to them. All I've done in the past is use whatever number we put on last year's application. Yep I know. Not very scientific.
Can SQF give any guidance as to what this actually means Glenn?
As for food safety, having a modular plan or separate complete documents for pasteurised, unpasteurised, whole nuts etc. Well to be honest, if you do it well it doesn't matter. If you do it badly or make mistakes it will matter. For that reason alone, I always rather not repeat myself. So if goods intake is shared, I will have that on one part of the plan and diverge at the point the processes diverge. No point having a plan for intake which is just copied and pasted. Etc etc.
