A Supply Cluster

The situation on arrival

A cluster of MSMEs, supplying to several different product builders.

Each unit had its own problems, and the cluster as a whole suffered from inconsistencies: operations, no shared operating system, heavy inventory, rejections and rework, and margins under pressure from all of it. Shipments went out in sporadic batches, which meant every customer downstream was buffering against the cluster’s unpredictability — and the cluster was buffering right back with inventory.

What we did

The work treated the cluster as one value stream rather than a dozen independent shops.

Applying lean thinking and methodologies across the entities, the cluster built assembly lines synchronised to takt time for daily shipment to customers, in place of the batch-and-hope rhythm it had been running on.

Daily shipment is a demanding discipline. It exposes every quality problem and every unreliable process immediately, because there is no inventory left to hide behind. That exposure is what drove the rejections and rework down.

What changed

The cluster turned around — consistent operations, lower inventory, better margins.

The more telling result came later. When the customer industry segments went into a slump, the cluster kept its neck above water — because lean operations meant it was not carrying the inventory or the cost structure that sinks a supplier when demand falls away.

Lean is usually sold as an efficiency programme. Its more valuable property is resilience: the ability to survive the demand you did not forecast.
