We ensure flow down of requirements from the top down
This is the representation
which everyone and their brother uses to represent a ‘standard’ document
structure. It is supposed to represent the dependence of one on the other. I
will admit that often when I see this I think it should be placed up-side down
because I see the ‘Quality Manual’ or Systems Manual as the foundation upon
which the others are based. This representation, to me, better relays the
understanding of the quantity of documents in a particular level. This
‘normal’ representation also is easier to follow as the requirements flow
down which seems easier to comprehend than if the representation flows up -
but maybe this is just my being used to the ‘normal’ representation.
You should note that there
is a level or tier 5 in my documentation pyramid which is not on ‘normal’
representations. I include this level / tier because every company has ‘ad
hoc’ documentation of some sort from time to time. For example, a process
engineer may have a temporary (ad hoc) document to gather some specific
information about a process for analysis. The documentation is not part of
the ‘normal’ process, but… The operator (or whoever) is taking data. Was the
operator trained for this? Is there a procedure or is the form ‘self
evident’? Just a few thoughts.
