Above all when something touches Dietmar’s core concerns: “In the middle of a building-materials delivery in western Styria, an older articulated truck breaks down with a transmission failure, and a replacement vehicle and a crane have to be organized at short notice” and “One of the workshop's most experienced mechanics quits in the middle of an already tense maintenance week, after a commercial-vehicle dealer poached him with a significantly better salary.” The bias that shapes Dietmar’s judgment most is “Availability heuristic (one case becomes the rule).”

Dietmar Grabner

Fleet manager, transport company for general cargo and building materials (around 120 trucks, in-house workshop) · Kalsdorf near Graz, Styria

◆ Synthetic persona — not a real human Buying Role: Operations Life-World: The Preservers · Home & Constancy Decides: rational 48 yrs · Austria

Dietmar Grabner (48) trusts no number he hasn't checked himself. For eight years he's run the fleet of a Styrian transport company for general cargo and building materials in Kalsdorf near Graz: around one hundred and twenty trucks spread across tractor units, bodies, the workshop, and driver assignments. From car mechanic to workshop manager to head of the fleet department — a path that has never once taken him off the shop floor.

Tech affinity

With anything he can open up and repair himself, he's highly competent — a diagnostic device in his own workshop holds no worries for him. Software and cloud portals stay more foreign to him; a dashboard only wins him over once someone shows him live how it solves an actual breakdown faster.

Defining bias

One conspicuous axle failure on a particular model series is enough for him to mentally write that series off for the next procurement, no matter what the failure statistics for the whole fleet actually say. The unremarkable vehicles that have run without complaint for years barely cross his mind.

How he decides

Technical decisions rarely mature at his desk: he walks the shop floor first and asks around with the shop foreman before any figure counts for him; an offer without that workshop sign-off just sits there, however cheap it looks. With people, on the other hand, he relies too quickly on the first day working together; he only brings in management once he already has a clear direction himself.
