Before software programs simplified the process of creating and maintaining part numbers, most companies relied on manual logbooks with highly intelligent (categorized) numbers. Manufacturers use part numbering schemes to assign a unique number to each part. Having the right part numbering system and approach is critical to make it easy to reference, re-use, and avoid part numbering related mistakes. If the part is still in design and has not been ordered, you can continue with the same part number.Manufacturing sophisticated high-tech electronics and medical device products requires the use of many parts-anywhere from thousands to tens of thousands. Still, a function in the context of maintainability, serviceability, and upgrade throughout the unit’s life and the ability to manage recalls more effectively.Ĭonclusion: changing the level of traceability impacts the function Overall conclusionĬhanging the traceability of a part when it has already been ordered requires a new part number to be able to separate traceable from non-traceable units. If you change it, you impact the function, maybe not its primary function in the context of the product. Although this might not be obvious, the level of traceability is a requirement of a part. When you only have a part number, you cannot track or trace each unit. The part with serial number allows for each produced unit to be traceable throughout its life. If the part was not serial traceable before and now it becomes serial-traceable, it means you have changed a function. There might be places where you cannot put a label, but in most cases you will find a spot where you can apply the label/marking.Ĭonclusion: fit is not likely to be impacted Function If, however you need a different label, it requires a change to the Bill of Material, and it needs to be positioned on the part.Ĭonclusion: there might be an impact to the form depending on the actual situation FitĪdding a label or marking does not typically impact the fit. It just will contain a bit more information. Hence it does not require a change to the form because you already have the label. It can be that you have a generic label for non-serialized and serialized parts. Serial numbers require a label or marking or an RFID label on the part. Let’s break this down using Form, Fit and Function: Form So going from a Part that is not serialized to a serialized part. I recently was asked if changing the level of traceability of a part requires a new Part number.
