BOM Feasibility Review Case
BOM Feasibility Review Case
A BOM at the NPI stage is rarely complete. Some lines carry a specification but no part number. Some part numbers turn out to be discontinued once you look them up. Others have lead times that will never fit the development schedule.
Send the BOM to SyncTronics and we work through it line by line for connectors, cables and electromechanical components, filling in suggested part numbers, pricing and MOQ on your own sheet so purchasing and NPI have something to act on.
A Real Case: The Line That Only Said “2.54 2x5”
One line on a BOM gave us two pieces of information: a specification reading 2.54 2x5, and a BOM No. of J9.
No description, no part number.
Those two were enough to establish a direction. A reference designator beginning with J indicates a connector by convention, and 2.54 2x5 points to a 2.54mm pitch, dual row, 10 pins in total.
The difficulty is that a great many connector types fit that description, and none of them could be pinned to a specific part number.
Rather than keep guessing, we narrowed the options.
The pitch and pin count together point toward a few likely directions. So what went back to the customer was not “insufficient information to quote,” but three specific questions:
- Is this a pin header or a female header?
- If so, what height is required, and what plating grade do the terminals need?
- If it is neither, please tell us the actual product name or what function it serves, and we will take it from there.
The customer passed these three questions to their end customer’s NPI team, and the answer came back quickly: a pin header.
Why Narrowing Options Beats Asking Again
The value in this approach is the round-trip time it saves on the other side.
An NPI engineer may be verifying hundreds or even thousands of parts at once. A supplier response saying “specification incomplete, please provide more detail” pushes that line to the back of the queue, because answering it means going back to the drawings and working it out again.
Three multiple-choice questions are different. One look at the design is usually enough to answer them. For the NPI team, the cost of responding drops from ten minutes to ten seconds.
The more specific the information, the faster the other side can confirm. That is the single biggest accelerator in the whole BOM review process.
Two Passes Through the BOM
Once a BOM arrives, we work through it in two passes.
First pass: lines with a part number
Each one is checked for current availability, actual lead time and MOQ conditions, with an alternative suggested against the specification of that part number.
This pass moves fastest, because the part number gives verification and comparison something to work from.
Second pass: lines with a specification but no part number
This pass needs back-and-forth with the customer. We work from whatever specification exists to narrow the possible range, then use the approach above to get the specific conditions confirmed. Only then can a part number be identified.
Separating the two is a matter of efficiency. The lines with part numbers can be quoted without waiting for everything else to come in, so you have cost and lead time on the bulk of the BOM early.
The Three Most Common Problems on a BOM
In order of how often we see them:
Incomplete specifications. The most common by far. Dimensions without a type, a description without a specification, or a specification that stops halfway. These lines need the confirmation process to fill the gaps.
Long lead times. The part number is clear and still in production, but the lead time will not meet the development schedule. We include alternatives with shorter lead times for these.
Discontinued parts. An EOL or PCN notice has been issued and the part can no longer be purchased. These need stock sourcing and alternative evaluation handled in parallel.
These three frequently appear together on the same line. A specification turns out to be incomplete, and once resolved, the part turns out to be discontinued as well.
The Format We Send Back
Once the review is done, we add three columns to the customer’s original BOM:
|
Column |
What goes in it |
|
Suggested part number |
A supplyable part number or alternative option |
|
Price |
Unit price for that part number |
|
MOQ |
Minimum order quantity conditions |
Your existing columns and row order stay exactly as they were, with these three appended. Nothing needs reorganizing, and the file can go straight into your internal process.
Out-of-Scope Lines Are Left Blank
Where a BOM includes active components or anything else outside connectors, cables and electromechanical components, we skip the line and leave those columns blank.
Annotating every line with “we do not supply this” only adds to the reading. Anything outside our core categories is simply left blank. A blank tells you immediately that the line needs to go to a different type of supplier.
Customers who work with us regularly tend to screen the BOM before sending it. Even without screening, skipping out-of-scope lines keeps the review moving at the same pace.
Who This Applies To
- An NPI-stage BOM with missing part numbers or unclear specifications
- Lines on a BOM with no traceable source, where it is unclear whether the part is discontinued or the number is wrong
- A need for a quick picture of availability, lead time and cost across the whole BOM
- A lengthy end-customer verification process where fewer round trips would help
- A preference for handling connectors, cables and electromechanical components through a single point of contact
