Agree with other respondents that there are way too many KPI's to give one answer, but IMHO, when I boil it all down, and if I could only know one KPI, it would be "Contribution Margin / Contribution Margin Ratio", both for individual products, but also for product lines. (Which I know is a little non-standard) Sometimes it's hard to calculate exactly, but when I do the math I just try to be accurate more than precise and comfortable with some uncertainty in the calculation.
In my experience, contribution margin is a key component to any business model (like maybe top 3 along with capital intensity and market size, but I'm just riffing here), and I think of it as a much more nuanced and useful version of GPM.
If you have a high contribution margin ratio, you can often sell your way out of problems, and thus more than anything you need a sales team that can sell sand at the beach.
If you have a mid to low contribution margin ratio, you usually can not sell you way out of problems, and instead you need to cut your way out, meaning you need to create relentless and savage cost control systems.
For example, with a 10% CMR, (ie LOW) for every dollar increase in opex, you need to generate $10 of sales just to run in place. It's often much easier to just cut $1 in expenses than generate $10 in sales, so the big lever is on the expense side. Conversely, with 80% CMR, (ie HIGH), for every dollar increase in opex, you need to increase sales by $1.25 just to run in place; so in that case the big lever is on the expense side of the P&L, meaning you can sell your way out of trouble, and it's almost impossible to cut your way out.
High CMR? You can often service a small market. Think small town pizzaria (Pizza has huge margins)
Low CMR? You must be in a large market.
Knowing your CM and CMR is also critical to understanding break even points, CVP, margin of safety, etc.
My two bits, hope it helps!

Subject: KPIs for Manufacturing Company
There are often too many KPIs tracked and "managed". The most basic variables are the direct materials, direct labor, and sub-contracting expenses. Measuring and controlling these costs to generate a superior Gross Margin (2nd most important KPI) will make a difference in financial results. Obviously, all other costs system should be tracked and trended in groupings that highlight variances for action. (Often tracking these two measures on a 12-month rolling average is a good start. Ideally, these averages should have an "upward" slope.)
Here is what a professional acquirer would be looking for in a transaction (and what creates a stronger company):
Growth of Revenues: Above the industry growth rate and preferably > 8% compounding. (Businesses in growing industry segments get more interest. Growth sells ... and normally makes managing easier overall.)
Consistent and Growing Gross Margins: Since books are kept differently this percentage varies, but often should be >30% and growing faster than revenue.
Bottom Line Profitability: EBITDA > 15% ... and potentially increasing over time to 18% of sales.
Diversification of Customers/Vendors/Management: No single critical vendor; No customer > 15% of sales; No manager responsible for > 25% of operating results.
Repeatable Systems in Place: Overall consistent financial results can confirm these systems benefits via contribution to revenue growth and growing net cash flow.
(Revenue Generating Business Segments: Cost inputs to develop sales should be measured against the marginal increase. i.e. collect data points on the input vs. output (sales) for these costs.)
(Quality control ... low scrap and not "upsets" ... One or two measures here are important to manage QC and to focus every person in the plant on the importance of being a quality leader.)
(Deliver times are very important for new orders and re-orders. Collecting this information and driving for improvements in delivery time may be critical to customer acquisition and retention.)
(If there are significant Sub-Contracting inputs to most products those deliver times and quality levels should be measured and "managed" as the same internal measures.)
Each manufacturing business operation may have drivers that ultimately control the metrics listed above. Finding the fewest of these to monitor is the key in any functioning, successful business.
Small improvements in all areas of operation add up to create a business that is easier to manage and much more valuable.
Best,
