Episode 07 / 08 · Four ways to put Carbon × Kaizen into practice · About 4 minutes

Four +E methods. Four useful questions.

Forget the acronyms for a moment. Ask which work step could be better, then look at time, quality, electricity and evidence together.

And… action!

A-Qin

IE, OEE, TPM, ROI... is there a simple version?

Yes. How to do the process, how well the equipment is doing, what should be checked and repaired, and whether the investment is worth it.

Ask about energy and evidence alongside each question, so you see the whole picture.

What I'm most afraid of is that you will find that the fastest step is not necessarily the one that consumes the most power.

IE+E | Could this work step be done better?

Put work time, movements, waiting and electricity on the same process map. The longest step may not use the most electricity. Brands and suppliers can choose a specific step to improve, agree on a trial and check the result together.

OEE+E | Faster production—but better quality and less energy too?

Read overall equipment effectiveness (OEE) alongside electricity per good unit. Use consistent definitions for operating time, speed and quality. The +E means considering energy alongside OEE—not adding kWh to a percentage. Higher OEE does not guarantee lower electricity per good unit.

TPM+E | Who should investigate this change?

A change in electricity use under otherwise similar conditions is a reason to investigate. Check for changes in product, load or measurement first, then ask maintenance staff to look into it. A curve alone cannot predict when a machine will fail.

ROI+E | Will the savings cover the investment?

List the equipment and integration costs, realistic savings and extra maintenance costs separately. Extra output only brings a cash benefit if it can be delivered and sold, with added costs deducted. Payback period and return on investment (ROI) answer different questions.

Pause here. What would you choose?

Brands want suppliers to improve. Which sentence is closer to IE+E’s approach?

Answer: Work together to identify waiting and rework processes, support small-scale testing and confirm results — Yes. Looking at work steps, time, electricity and quality together gives both sides something practical to improve.
