RE: Capability (C045): representing_product_as_realized

Thanks Gordon

I see what you are saying but I would have thought that what you describe is really a different configuration of an individual Harrier, not a version.

I always understood a version to mean a product that has had a change made to it. E.g.

My car has had a product recall and a new brake assembly fitted.

The car is now at version 2.

The change to the brake assembly was not a configuration option, but the result of a change directive (choose your favourite business term). Hence there is a new version of the car. I would never remove the brake assembly unless another change was to be implemented. In your Harrier examples, the Harrier is being configured according to mission, not according to product changes.

I understand that some products have a “strike” plate which gets marked according to the changes that have been implemented.

The product has the same serial number, but the changes has been applied, so the configuration record reflects a new version.

Regards
Rob

Hi Rob,
I note the following issue is still open

Issue: RBN-1 by Rob Bodington (04-03-13) minor_technical issue
Resolution: Accept. Status: open

How are Product_as_realized versioned? Does each version keep the same serial number and then just have a new version number assigned?

ANSWER - Yes - the product keeps its original serial No. thru life. The version depicts its operational 'capability'.
e.g - A Harrier GR 5 serial ZX 138 is a day attack fighter/bomber, the same aircraft (ZX 138) converted to a GR 7 version provides an additional night attack capability. On the product configuration status record (CSR) it would show additional OEM references, a CUM No. ( a as designed serial number as identified on the drawings; a LBS (line build sequence) No as depicted on the manufacturing process. This provides the traceability of the product thru both 'design and manufacture linked to the actual operators serial (in this example 138)

I understand in a commercial aircraft environment the OEM serial for the product would be the 'master' in respect to the realized products CSR, the tail no. would be a 'master' in respect to operator.

In the PLCS bike example the serial of the bike remains the same irrespective if it is in racing or road wheel 'trim'/version.

regards
Gordon
