ASEAN cold-chain economics in 2026: where the carrier consolidation is going.

Our analysis of carrier rate cards across five ASEAN markets suggests another 18 months of consolidation pressure.

Most operational excellence engagements begin with a methodology. The consultant arrives with Six Sigma certification, or Lean experience, or a digital operations playbook — and the engagement bends to fit the methodology. Twelve weeks later, the client has a kanban board on a wall and a value-stream map in a binder. Six months later, the wall is repainted.

The constraint, not the framework

The constraint is what governs the operation today. It might be a single bottleneck workstation. It might be a planning system that can’t handle SKU complexity. It might be a maintenance organization that has no visibility into asset performance. Whatever it is — the constraint sets the ceiling on every other improvement you can make.

When you start with the methodology, you optimize wherever the methodology is most comfortable being applied. When you start with the constraint, you might end up applying lean, or Six Sigma, or digital operations, or none of these — but you’ll be applying it to the part of the operation that actually matters.

What this looks like in practice

On a recent apparel engagement, our team spent the first fourteen days doing nothing but observing the operation. No kickoff workshops, no methodology training, no PowerPoint decks. We mapped the constraint. It turned out to be the production planning system — not the line, not the operators, not the maintenance organization. The line was running well. Operators were skilled. Maintenance was adequate. The planning system was the ceiling.

We rebuilt the planning system. The line ran 22 percent faster as a result. Operators didn’t need additional training. Maintenance didn’t need additional capex. The constraint moved — from planning to changeover time at one specific workstation. We solved that next. The constraint moved again. After nine months, the operation had a 31 percent lower conversion cost — measured against an audited baseline, verified by client finance.

The methodology you used in the end was lean. But you couldn’t have known that on day one. Anyone who tells you they know on day one is selling you a hammer.
