#505: How to Find the Bottleneck That's Eating Your Margins

August 6
1h 15m

Episode Description

You broke your margins out by line last month and one of them came in under target. So you asked your operations manager what happened, and you got told the team is drowning and needs two more people. Then you asked your CFO, who told you you're already overstaffed. Both of them are looking at the same business and neither one is lying. Kim and I recorded this one as the follow-up to the margin episode, because breaking margin out by line tells you that something moved and it will never tell you why. The why lives in three places: whether your people are producing, whether the work is moving, and whether the money is moving. Kim brought the number that makes the case. At one of her clients, the rates of change went negative nine months before the margin actually hit its floor. Nine months of warning, sitting in a report nobody was reading. We got into utilization and the fight every exec team has about the denominator, first-call effectiveness in my old copier business, inventory as trapped cash, and why I would not let anybody build a dashboard or an AI tool until they can name the bottleneck it opens.

Top 10 Takeaways

  1. Your income statement tells you the margin moved. It cannot tell you why.
  2. Every system has one bottleneck. Fix anything else and nothing actually gets faster.
  3. Three places hold the answer: your people, your throughput, your working capital.
  4. Utilization is one question. What did you bill against the payroll you paid for?
  5. The team average hides it. Go look at how individual people spend their days.
  6. Every repeat service call doubles your delivery cost and quietly eats flat-rate contracts.
  7. Pulling people out for training feels expensive. It is usually the cheapest capacity available.
  8. Two years of inventory is not product on a shelf. It is trapped cash.
  9. Privately held companies self-fund growth near 20 to 25 percent. Past that you borrow.
  10. Choose your AI projects by bottleneck. A dashboard tied to nothing goes nowhere.

Sound Bites

"There was about a nine month lead time between what you were seeing in the rates of change and what was actually happening in the margins." (@00:02:17) — Kim Clark

"We need to open up the bottleneck and have more throughput at the exact margins that we want. And that's not going to be on the income statement." (@00:02:36) — Ryan Tansom

"Everyone says, I need more help. What are you doing with your time?" (@00:15:53) — Ryan Tansom

"Claude will gladly build you a bunch of dashboards. And it's a dashboard to nowhere, because it's not tied to anything." (@00:57:39) — Ryan Tansom

"Milestone 17 is helping us focus on the right thing, which is the throughput of the bottleneck in relationship to the goal." (@01:12:37) — Ryan Tansom

About This Episode

This is the second stop in Module 6, Transferable Margins, and it picks up directly from Ep. 504. That episode made margin visible by line and put a target on each one. This one is the diagnosis layer: when a line comes in under target, where do you look, and what do you do about it. Kim Clark is iBD's Chief Revenue Officer and co-hosts the Module 6 run. Module 6 closes with the business operating system that holds the whole stack without the owner.
