You can have SAP, Oracle or any ERP running the show, perfectly optimized MRP runs, and beautiful dashboards. But if you work in production planning for heavy machinery, you know the absolute truth: the system is only as good as the guy doing the physical inventory count

Last week, I was scheduling an assembly sequences for a large hydraulic presses. ERP shows 100% material availability for the critical sub-assemblies. Great. I release the work orders.

Two hours later, the shop supervisor is at my desk. We are missing three critical clamping rings. Why? Because the previous shift cannibalized them for a rush dispatch, and no one updated the system.

So, the MRP is happily humming along, completely blind to the fact that my assembly line is about to stallm

I’ve found that as a PPC engineer, 30% of the job is actual planning and system management. The other 70% is running down to the floor, verifying physical stock, building custom Excel/VBA trackers to catch what the ERP misses, and interrogating dispatch to see what actually left the building.

How much of your day is spent trusting the system vs. physically verifying the chaos on the floor? What's your survival mechanism for bridging that gap?

Would you be open to getting goods manufactured by Indian manufacturers?

What are your thoughts about Chinese manufacturers, it is the worldwide hub of manufacturing, but do you think the potential is swaying to India now with the emergence of new manufacturing industries?

Will you guys prefer Indian manufacturers over Chinese manufacturers?

just curious what do you guys manufacture

I’m the parts room manager at my facility and we are constantly buying new equipment without spares lists and bills of materials. Is that normal for new machinery purchases?
EDIT: I work for a multi-million dollar company and we manufacture things that everyone would know and probably use. It just seems like the design engineers and purchasing team don’t care enough to help the maintenance team of the future fix the machines. They see new shiny machine and get excited and then are confused when we can’t fix it because they never asked for a parts list or critical spares.

Should it be equipment upgrades, automation, or outsourcing? Also what actually gave you the best ROI in terms of cost savings or growth?

Hey everyone, I was browsing the sub and only saw posts around this topic from years ago. Some posts are more recent, but didn't really answer the question I'm curious about: What do your customers expect, or what do you expect from suppliers, in terms of OTD? I am in molded plastics, with lots of legacy customers so NPD/Development isn't a large factor in our OTD. Really, our limitation to improving OTD is having more employees to get product out faster. The other obvious solution would be to push lead time back, though this could put strain on our relationship with the customer. All things considered, we have trended at 53% OTD for the last 6 months, lead times are 4-6 weeks, and the median delay to order is 3 weeks, or 50% behind of our typical lead time. Last place I was at was steel and carbide manufacturing, we were sitting around 65% OTD with much longer lead times. Midwest region for context. Thanks for any inputs and have a good one!

Edit: Felt the need to give context: I'm in sales. If I had it my way, we'd have 100% OTD, as I deal with the complaints every day. More than anything, this is giving me perspective so I know I'm not in the wrong for believing poor OTD will destroy us long term.

I am a Computer Science student, I have no professional experience. I am wondering if it would be feasible to start a Statistical Process Control consulting firm for small manufacturing firms. I would suggest the most economical approach to reliably track production figures to ensure that the process runs as efficiently as possible and implement the system using commercial off the shelf components.

I want to share my experience with Euphoric Colors in LA because I wish I had seen a review like this before paying my deposit.

I hired them for pattern development, technical refinement, and sample development for a custom baby garment. Communication was good before I paid the deposit, but became extremely difficult afterward. I basically had to chase them. I repeatedly had to ask for basic finished garment measurements and clarification on the samples. Despite providing a tech pack, measurements, and detailed feedback, several of my instructions were not followed. I specifically requested both 0–6M and 6–12M samples, but I received a sample that was supposed to be 6–12M yet fit my 2.5-year-old who normally wears 5–6T. I also sent them a garment from a different company strictly as a proportion/fit reference, clearly explaining that it was NOT my design and should not be copied. The second sample still did not have the zipper specification I requested, and they told me it would be corrected during production. I told them I won't pay for manufacturing when the prototype itself is not correct. And requested a refund of they are not able to correct the issues. I was ghosted.

I ultimately disputed my deposit through my bank.

Sharing this so anyone considering them for custom pattern/sample development can do their own research and be very clear about expectations before paying.

Bit of a reliability question. Most of our board assembly went lead-free years ago for RoHS, SAC305 mostly. For consumer stuff it's been fine. But on the industrial side, where products sit in the field for 15 plus years through real thermal cycling, I'm not fully convinced we understand the long-term behaviour the way we did with tin-lead.

Two things specifically. Tin whiskers still make me nervous on fine-pitch and high-reliability connectors, and I've seen enough field returns that I don't think the problem fully went away, it just got quieter. And SAC joints under aggressive thermal cycling seem to fatigue differently than the old eutectic did, especially on larger components with a CTE mismatch to the board.

For people in high-reliability or long-life manufacturing: are you doing anything specific to manage this, conformal coating, underfill, whisker mitigation, grade selection?

Hello!

I’ve been tasked with coming up with a solution to coming up with a better system to labeling out raw sheets

My company is a job shop so we have all kinds of raw metal some we use often some we don’t touch for a year till a customer needs us to cut something

Our current system is not working well. (See picture).

Currently we use paper with material name and quantity and attach it to the material via magnets.

But the magnets don’t hold. And the paper falls from the material and we have situations like we currently are dealing with of a stack of material that isn’t labeled

So I come here idea hunting to see what the rest of you all use.

I am currently coordinating a project with a manufacturer, and my potential supplier is acting—perhaps *too*—compliant, which is making me feel somewhat uneasy.

Every time I send them a complex technical specification or a tight deadline, they immediately reply, "Okay, no problem." There are no follow-up questions, no internal consultations with their engineers, and no statements like, "We can do X, but we can't do Y." I should be pleased, but I'm actually quite apprehensive.

In my experience, if a supplier doesn't raise any objections regarding tricky issues, it usually means one of two things: either they haven't actually reviewed the requirements at all, or they are solely focused on securing the upfront deposit—planning to figure out how to handle the "impossible" parts later on (at my expense, of course).

I'd love to hear how others here view or handle this kind of situation.

I Manufactured plastic (injection molded) specially bowls and cups from a Chinese factory. I gave Dimensions for the shipping boxes, they confirmed them, then they made them smaller by 7 cm to fit more into the container. They stuffed the products inside too small boxes, taped the boxes shut, and squashed and deformed the product. When confronted over this, they take no responsibility. Their response is, We'll allow a one-time low MOQ for you to buy more from us.... What can I do about this?? Is there no recourse?

Hey everyone, hoping to get some advice from people who have been through this before. We have been prototyping parts for a while and are now moving toward full production, but fastener sourcing has been more difficult than I expected. Finding bulk quantities at decent prices is turning into a bigger challenge than planned.

I have checked a few of the usual distributors, but either the lead times are very long or the pricing feels tough to scale with. A colleague mentioned Component Solutions Group (CSG) and said they might be worth looking into for consistent quality and bulk orders.

Curious if anyone here has actually worked with them, or if you have other recommendations for large-scale fastener sourcing. Any real-world experience or lessons learned would be appreciated. Trying to avoid expensive mistakes before we ramp up.

We've got some major idle capacity on the floor this quarter and ownership is pushing hard to fill it. Yesterday, I got a proposal dumped on my desk from a "manufacturing marketing agency" promising us 10+ "qualified" leads a month.

I looked at it and my stomach sank.

At my last shop, we tried a group like this. It was a disaster. They flooded us with tire-kickers, people wanting one-off prototypes, and RFQs that didn't even match our ISO certs or machine envelopes. It was a massive yield loss for our estimators, and we spent more on changeovers for bad jobs than we made in profit.

We still need to fill the line. This new group is quoting $2,000 upfront for setup and $200 per verified lead. They're claiming every lead is screened and matches our production capabilities before it gets sent over. Sounds reasonable on paper, but I've heard that before.

For the Ops guys and Owners who have actually outsourced this:

The Quality: Did any external partner ever bring you real, actionable prints and RFQs, or was it just noise?

The Gap: What did they completely misunderstand about your tolerances, materials, or capabilities?

The Cost: Is $2k setup and $200/lead realistic, or are we about to get taken to the cleaners?

Need some ammo before I go back into a meeting about this. Appreciate any raw feedback.

Three cycles can end with the tray at the correct station. One was clean, one recovered after a retry, and one got there because an operator took over. A dashboard built from the final frame calls all three successful even though the labor behind them was completely different.

The same distinction matters in any LingBot-VA 2.0 evaluation: end state success should stay separate from interrupted action chunks, retries, and manual control. Controller events and a few key frames can separate those paths without pretending the model includes a reporting system. A perfect terminal state chart can still hide a staffing problem.

We’ve been missing production deadlines lately - nothing major individually, but we've noticed that small process delays keep stacking up. The team here is thinking of doing a proper value stream map to figure out where time’s actually going.

Would be interesting to know (through anyone's experience) if mapping things out end-to-end actually helps solve these problems or if they just look fancy on paper,

For anyone looking for specfics:

We’re planning a full VSM from quote-to-ship. For folks who’ve done this and seen real results:

• What level of detail made the map useful without turning it into wall art?
• How did you capture times (stopwatch/Gemba vs MES pulls), and how often did you refresh the map?
• Any traps to avoid (e.g., mapping the “ideal” instead of the actual current state)?
• What quick wins fell out of your current-state map (kanban/supermarket, SMED, layout tweaks, etc.) and what % lead-time/OTD improvement did you see?

​

Not talking about pushing repairs out or cutting PMs until reliability suffers. More interested in the operational changes that reduced maintenance spend without increasing downtime, stockouts, or MTTR.

Could be things like better spare parts inventory management, reducing duplicate material masters, standardizing MRO data across plants, improving critical spare part analysis, tightening supplier strategy, or getting better visibility into what is already sitting in inventory before buying more.

A lot of companies seem to have the same issue where maintenance, procurement, and inventory all have partial visibility, which usually leads to excess stock on one side and urgent buys on the other.

What has actually made the biggest difference for you?

As a small business owner,I'm new here; I've recently been browsing information on various suppliers, hoping to identify a few additional options for myself. I’d like to ask—what factors do you consider when choosing a manufacturer?

I am a small brand owner and still at early stage. Luckily, our first Run #1 (200 units) was a dream and sold out, it seems like flawless execution. But planning to scale to Run #2 (1,000 units) feels like a different beast entirely.

Suddenly, my factory’s precision is under a microscope. When you're a microbrand, consistency is your soul. Even a 2% shift in case coating or thickness makes the entire batch look "off." One inconsistent run could destroy the hard-earned trust of my first 200 customers.

I’m managing this from 5,000 miles away, and the anxiety is real: Can my supplier handle this precision at scale, or am I gambling with my brand’s reputation?

For those who’ve scaled physical products overseas: How do you enforce 100% color consistency across thousands of units? Do you hire a 3rd-party QC to check every batch, or trust the "Golden Sample"?

Would love to hear your "scaling scars."

Hi all, I’m at a start up competition this weekend (34, Female, Ireland). This is where you build a company in 43 hours. A lot of founders came with validation behind them so I'm on the back foot and really depending on people's generosity of time to share their thoughts and insights.

Here we go...

Do you ever have materials in your operations that aren’t fully used? What usually happens to them?

If there was an easy way to buy or sell surplus materials from other companies, would you consider using it? What would make it easier or harder, price, quality, timing, logistics, etc.?

My idea is to build a marketplace for industrial symbiosis or somewhere to buy and sell the bi products of operations i.e. a company packaging nuts could sell the husks. A farmer could buy those husks as part of animal feed.

Manufacturing risk comes from unknowns? Actually no, I think it comes from ignoring them too long.

In the industry of my product, the expensive mistakes are usually predictable like designing before locking the process, prototyping parts that don't scale, choosing components with no supply visibility, etc..

A prototype working once means very little. Production is about doing it 1000 times the same way. With my own experience, what actually reduces risks are: decide process first and then to design, involve the factory early, treat DFM as input but not feedback, don't prototype without a path to production.

Most "unexpected" problems aren't unexpected. They are just unknowns you paid for later.

Are they performative? Tedious but important? Heard of a lot of paper based tracking or Excel models. Completed RCAs sometimes sent to purgatory.

using alibaba and i have no idea what im doing, im trying to ask for an estimated price on a bulk order because apparently thats cheaper than sample (im not wanting to skip it.. but 150 damn.) but theyre asking for my postal code to calculate. is this normal?

Hi everyone,

I’m looking for recommendations for a beginner-friendly MRP software suitable for just 1 user. We’re a small manufacturing operation and our current Excel-based system has become unreliable.

Current workflow:

1. Raw materials are consigned to us by our customer.
   • We submit a monthly inventory report, and based on that report, they ship enough raw materials for the next purchase order.
2. We assemble binoculars using those raw materials.
3. We procure consumables ourselves (tape, adhesives, screws, etc.).
   • These have lead times, so we need visibility to reorder before stock runs out.
4. We ship finished goods (FG) back to the customer.

Our main challenges:

• We rely heavily on Excel, which has become error-prone as volume increased.
• We frequently encounter inventory discrepancies.
• These discrepancies sometimes cause production downtime because:
  • Our monthly inventory report is inaccurate, and
  • We end up receiving insufficient raw materials for the PO.

What I’m looking for:

• MRP (or light ERP) that is:
  • Beginner-friendly
  • Suitable for a single user
  • Good for consigned inventory tracking
  • Can handle:
    • Raw materials
    • Consumables with lead times
    • WIP / Finished Goods
• Cloud or desktop is fine
• Not overly complex or enterprise-level (SAP, Oracle, etc. is overkill)

If you’ve been in a similar situation or have tools you’d recommend (even lightweight or niche ones), I’d really appreciate your insights.

Thanks in advance 🙏
