A seasoned management consultant and graduate of the UofM Carlson School of Management, he brings strategic leadership to a portfolio of manufacturing and automation companies delivering factory automation, contract assembly, facility relocation and expansion, and supply chain localization across the U.S. and Latin America.
A wrong contract assembly partner does not just cost you the bad parts. It costs you the engineering time you spend on rework, the customer credibility you spend on missed dates, and the management attention you spend managing the partner instead of running your business. The total bill is usually 5 to 10 times the unit cost differential you thought you were saving.
Here is a fast filter. If a candidate hits any of these seven, walk.
If a contract assembler reads your drawing and quotes back inside a day without asking about critical tolerances, quality acceptance criteria, or your inspection plan, they are quoting from a template. The quote will be tight. The first article will fail. The change orders will come.
Confidentiality is fair. Total opacity is not. A real partner can describe the kind of work they do — "heavy industrial OEMs in the agricultural equipment space" — without naming names. If they cannot describe their book of business at all, they may not have one that resembles yours.
Ask to see their nonconformance procedure, their corrective action process, and a sample CAR. If they cannot produce it in 48 hours, they do not have one. AS9100, ISO 9001, IATF 16949 — the standard matters less than the discipline. The discipline is either documented or it is not.
Every operations leader knows their OTD. If the answer is "we are usually pretty good" or "it depends on the program," the answer is "we do not measure it." A partner who does not measure cannot improve.
A long equipment list is not a value proposition. It is a brag sheet. The right partner leads with how they solve problems and brings up equipment when it is relevant to your specific build. Lead with capacity, lead with capability, lead with problem-solving — equipment is supporting evidence, not the headline.
If you ask "is there a better way to build this assembly?" and they answer "we will build it however you draw it," you have an order taker, not a partner. A good contract assembler will push back on a design choice that adds cost without adding function. That pushback is worth the margin.
If your account is going to bounce between sales, project management, and production, you will spend the next twelve months re-explaining your program every two weeks. A real partner assigns ownership.
Once a candidate clears the seven flags, ask these:
The answers tell you whether you are buying a relationship or a transaction.
DPG operates two contract assembly companies — Source Engineering & Manufacturing for electrical and wire-harness work, Hedgehog MFG for heavy industrial. If you are evaluating partners and want a sanity check on what good looks like in this space, we are happy to share what we look for in our own shops.
