Discovery Call Questions for Manufacturing Sales

Manufacturing buyers measure everything in throughput, downtime and cost per unit, and they have seen plenty of vendors promise savings that never showed up on the plant floor. These discovery questions are written in their vocabulary, so you can get to a real production problem and a real capital approval path in one call.

What Manufacturing buyers care about

The buyer is a plant manager, a VP of operations, a head of supply chain or quality, or, for capital purchases, an engineering or maintenance lead who writes the justification. Their world is physical: lines that run or do not, shifts that are staffed or not, raw material that arrives on time or late. They think in overall equipment effectiveness, scrap and rework, on-time delivery, lead times and labor hours per unit. Many run lean or continuous improvement programs and will expect you to understand that language too.

They are judged on output against plan, unplanned downtime, quality escapes, on-time delivery to customers, safety incidents and cost per unit. Senior operations leaders are also measured on capital efficiency: whether the money spent on equipment and systems paid back in the promised time. A plant manager who misses output targets has a short career, so they are cautious about anything that could disrupt a running line.

They are wary of software vendors who have never stood on a plant floor, and of anything that requires operators to change how they work without a clear reason. They have ERP and MES systems that were painful to implement and they do not want to repeat that. They respect reps who ask about shifts, changeovers and the maintenance backlog, and who do not flinch when the answer is messy.

Situation questions

A high-mix job shop, a continuous process plant and a discrete assembly line have almost nothing in common operationally, and the plant manager will decide in two minutes whether you know that. Establish the type of production, the number of sites and lines, the shift pattern and the systems before you ask about problems.

  1. What do you make and how: discrete assembly, batch, continuous process, high-mix low-volume, and how many sites and lines are we talking about?
  2. How many shifts do you run, and how staffed are they relative to plan right now?
  3. What systems are in place today for ERP, MES, maintenance and quality, and how much of the plant floor data actually flows into them?
  4. How do you measure performance at the line level: OEE, units per hour, scrap rate, and how is that reported upward?
  5. What is driving this conversation: a customer requirement, a new product, a cost target, a capacity constraint, or a corporate initiative?

Pain questions

Plant leaders know exactly where the pain is because they get called at two in the morning when it happens. Ask about the last incident, the worst line, the longest changeover, and they will tell you more than any general question could uncover.

  1. Which line or asset causes the most unplanned downtime, and what usually takes it down?
  2. Where does scrap or rework concentrate, and how early in the process do you find out that something is out of spec?
  3. How long do changeovers take on your most constrained line, and what is the plan to reduce that?
  4. When a customer order is late, what is the most common root cause: material, capacity, quality or scheduling?
  5. What is the maintenance backlog like, and how much of the work is reactive versus planned?

Impact questions

Manufacturing buyers will not approve anything without a number, and they prefer their own number to yours. Ask them to cost downtime per hour, scrap per month and late deliveries per quarter, and let them build the business case in their own figures.

  1. What does an hour of unplanned downtime on that line cost you in lost output and labor?
  2. What is scrap and rework costing per month in material and labor, and what is the target?
  3. What do late deliveries cost you in expedite fees, penalties and customer relationships over a year?
  4. If OEE on the constrained line moved by five points, what does that translate to in units or revenue?
  5. What happens to the plant's capital plan or headcount if output does not improve by the next fiscal year?

Decision process questions

Operating spend and capital spend take different routes. A plant manager can approve a small operating expense, but anything that looks like capex goes through an appropriation request, corporate engineering and finance, often with a payback threshold. Find out which route you are on and what the threshold is.

  1. Would this be treated as operating expense at the plant level or as a capital request that goes to corporate, and what is the approval threshold?
  2. What payback period or hurdle rate does finance require for a capital project, and who builds the justification?
  3. Does corporate engineering, IT or a continuous improvement group need to sign off on new technology on the floor?
  4. How did the last system or equipment purchase go through, and how long did it take from request to purchase order?
  5. Are there union, safety or validation requirements that affect how something new can be introduced on the line?

Next step questions

Plant leaders will give you a site visit if you have earned it, and nothing moves a manufacturing deal like standing on the floor. Propose a specific next step with maintenance, engineering or quality involved, tied to a window when the plant can accommodate it.

  1. Would it make sense for us to come to the plant, walk the line in question and talk to the people who run it?
  2. If we scoped a pilot on one line, what would you need to see in the first ninety days to justify a wider rollout?
  3. Who from maintenance, engineering or quality should be in the next conversation so the technical questions get answered early?
  4. Given your shutdowns and production calendar, when is the realistic window to introduce something new on the floor?
  5. Is there anything about this plant or this corporate structure that makes you think this will not get through?

Red flags on a Manufacturing discovery call

  • The plant is under a corporate capital freeze or a cost-reduction mandate, and the contact is gathering quotes to show they looked.
  • The contact is a continuous improvement or engineering lead with no budget and no plant manager willing to sponsor the project.
  • They are mid-ERP implementation, which consumes every spare hour of IT and operations for a year or more.
  • They cannot tell you what an hour of downtime costs, which means nobody is managing to that number and there is no business case to build.
  • They want a guaranteed OEE improvement in the proposal before they will let you see the line, which no honest vendor can give.

Tips for running the call

  • Learn the vocabulary: OEE, changeover, scrap and rework, takt time, planned versus unplanned downtime, appropriation request. Misusing a term ends the conversation.
  • Ask what they make and how in the first minute. The answer determines everything else you should ask.
  • Ask for the site visit. Manufacturing buyers trust people who have stood on the floor, and you will learn more in an hour there than in five calls.
  • Separate opex from capex early. The approval path, the timeline and the people involved are completely different.
  • Respect the running line. Never propose anything that sounds like it could disrupt production without a plan for how it is introduced safely.
  • Build the business case in their numbers: downtime cost per hour, scrap per month, expedite fees. A plant manager will not defend your numbers to corporate; they will defend their own.

Frequently asked questions

What questions should I ask a plant manager on a discovery call?

Ask what they make and how, how many lines and shifts they run, which line causes the most unplanned downtime and what an hour of downtime costs. Then ask whether a purchase would be opex or capex, what payback finance requires and when the next shutdown window is.

How do manufacturers make purchasing decisions?

Small operating expenses can be approved at the plant level. Anything that looks like a capital project goes through an appropriation request with a payback calculation, corporate engineering or IT review and finance sign-off. Ask which route you are on and what payback period they require.

What metrics do manufacturing buyers care about?

Overall equipment effectiveness, unplanned downtime, scrap and rework, on-time delivery, cost per unit, labor hours per unit and safety incidents. Senior leaders also watch capital efficiency and payback on past projects. Ask for the real numbers on the line that matters.

How long is the sales cycle when selling to manufacturers?

A few months for plant-level operating purchases, nine to eighteen months for capital projects that go through corporate approval, and longer if a pilot is needed before the appropriation request. Shutdown windows and fiscal year timing often decide the actual date more than anything you do.

What is the biggest mistake reps make selling into manufacturing?

Talking about software features instead of the line. Plant leaders care about output, downtime and scrap, and they will tune out a product pitch. Ask about the worst line, the last outage and the maintenance backlog, and ask to visit the plant.
