The KPI HSB manufacturers never measure

Ask a prefab HSB manufacturer what their revenue was last year. You'll have an answer in a second.

Ask what their failure costs were. Long silence.

And yet the second number is usually three to five times larger than their profit.

Why nobody measures it

Failure costs are hard to track for three reasons.

First, they span departments. A wrong element becomes a crane hour in one ledger, overtime in another, a credit note in a third. No single line item aggregates them.

Second, there is no shared definition. Is a two-hour rework a failure cost? A delivered-late element that the site crew absorbed? A revision that was caught before production started? Different factories call these different things. Usually they call them "part of doing business."

Third, there is cultural resistance. Tracking failure costs means assigning cause. Assigning cause creates friction. Most managers prefer the quiet life.

The simplest possible tracking

You don't need a system to start measuring. You need four categories and someone in the office willing to tag events for three months:

1. Wrong or missing elements at site – any time the placement team cannot work because of something produced wrong or not delivered. Log time lost and crane status.
2. Production rework – any time the shop floor re-makes an element. Log hours and material.
3. Late revisions after production start – any time a change comes in after cutting has begun. Log whether it caused scrap.
4. Order errors on purchasing – any time the wrong material was ordered. Log quantity and supplier restocking fee.

Three months of this will tell you what your failure cost ratio looks like and where it concentrates. In most HSB factories, 70 to 80 percent of the total traces to the same two or three root causes, and almost always at least one of them sits in the handoff between BIM and production.

Once you've measured, the investment case writes itself

A factory doing €10M in revenue and sitting at the industry average of 8 percent failure costs is burning €800,000 a year. Halving it – which is realistic when the BIM-to-production handoff is digitised – is €400,000 a year back on the books. That's three years of most production-data software licences in month one.

The hard part was never justifying the investment. The hard part was measuring the gap.

We help prefab HSB manufacturers close the gap between BIM and production, where most failure costs live. If you've measured and it's ugly, let's talk.
