Build a Quality SOP Worksheet for Contract Manufacturing
A precision contract manufacturer lives or dies by its quality system: every work order needs a traveler that proves what was inspected and by whom, every nonconformance needs a documented corrective action, and every piece of test equipment needs to be within its calibration window before it touches a customer's part.
The fastest way to decide between Process Street and SweetProcess here is to build a one-page worksheet of your own quality workflow first, then see which tasks land on which side of it.

Which tasks repeat on a schedule or per work order?
List the tasks that fire on a trigger, a new work order opens, a piece of equipment's calibration date approaches, a nonconformance gets logged, and note who owns each one and what has to be true before the next step can start.
- First-article inspection sign-off before full production run begins
- Calibration due-date check before equipment gets used on a customer part
- Corrective action assignment and close-out deadline after a nonconformance
- Supplier qualification renewal before a new purchase order goes out
This column is your Process Street list: each row becomes a checklist that runs automatically when its trigger fires, with a blocking step that holds the next stage until the current one clears.
Column two: every standard that has to stay identical across the shop floor
Now list the standards a task in column one has to be measured against: what counts as a passing first-article inspection, what the corrective action process actually requires at each severity level, what qualifies a supplier for approval.
Those standards belong in SweetProcess, documented once and version-controlled, so an ISO 9001 or AS9100 auditor sees one current answer instead of three inspectors' personal interpretations of the same requirement. When the standard changes, and it will as customer requirements or the standard itself gets revised, you update the document once instead of retraining verbally.
This is also where a second shift or a new inspector benefits most. A checklist tells them the first-article inspection needs a sign-off; the documented standard tells them exactly what measurements and tolerances that sign-off is actually verifying.
What will an auditor actually ask to see?
Walk through what an ISO or AS9100 auditor typically pulls: a sample work order traveler with complete sign-offs, a calibration log with no equipment past due, a closed corrective action with root cause and verification of effectiveness. Match each of those against your first two columns.
If you cannot produce one of them quickly today, that is the gap to close first, not the item that feels most urgent day to day. Audit findings tend to cluster around whichever record was easiest to skip under production pressure.
A useful exercise is to pick one closed work order at random, without warning your own team, and see how long it takes to assemble a complete traveler, inspection record, and any related corrective action. If that takes more than a few minutes, an auditor will notice the same friction.
Column four: where a supplier qualification gap actually costs you
A supplier that slips out of qualification, an expired certification, a missed on-time delivery review, is invisible until a customer asks why you are still buying from them. Build a Process Street task that fires before each supplier's qualification review date, and keep the qualification criteria itself, what scores count as passing, in SweetProcess.
The cost of skipping this is rarely a single bad part; it is a customer audit finding that traces back to a supplier nobody had re-qualified in over a year.
Filling in the last column: who owns it once it is built
A quality system like this needs an owner, whether that is a dedicated quality manager or a plant manager wearing that hat part time. National median pay for an operations or general manager role, which often absorbs quality ownership at a smaller shop, is $105,770 a year1, a useful reference point when deciding whether to dedicate a role or spread the work across existing staff.
Once the worksheet is filled in, moving column one into Process Street and column two into SweetProcess is mostly a matter of typing it in; the hard part is doing the honest accounting of what your shop actually does today versus what your quality manual says it does.
Olivia, MeetMyCOO's AI COO, can help you walk through that honest accounting before you commit either tool, since the gap between the documented quality manual and the actual shop floor is usually bigger than a plant manager expects.
What Good Looks Like
A well-run contract manufacturer can produce a complete work order traveler, a current calibration log, and a closed-loop corrective action for any nonconformance an auditor asks about, without a scramble beforehand.

How to Get Started

Fits the recurring, triggered work: first-article sign-off, calibration checks, and corrective action deadlines tied to a work order or a date.
Fits once you are paying a mix of shop staff and outside inspectors or contractors and need it handled in one place.
Frequently Asked Questions
Do we need separate systems for ISO 9001 and AS9100, or can one setup cover both?
One documented system can cover both if it is built to the stricter standard's requirements. AS9100 layers aerospace-specific requirements on top of ISO 9001's baseline, so if you expect to serve aerospace customers that require it, building to AS9100 from the start can avoid rebuilding your documentation later.
What is the most common finding in a contract manufacturer's quality audit?
Incomplete or inconsistent nonconformance and corrective action records, often because the root cause analysis was skipped under production pressure. A documented, enforced process for closing out a corrective action is usually the highest-value fix.
How do we handle calibration tracking without a dedicated quality hire?
Assign the weekly calibration due-date check to a production supervisor or office manager as a recurring checklist task. Then document what happens when equipment is found past due, so the process holds even when the person doing the check changes over time.
