Der Bebauungsplan. The German development plan is a legally binding municipal instrument specifying, plot by plot, what may be built: permitted use, building lines, height, roof pitch, materials, the number of storeys, sometimes the species of tree. It is not guidance. It is law, and a building permit is measured against it.
The project management standard
The German standard for project management defines the terminology, the process model and the required documents. Project management in Germany is itself standardised — there is a DIN number for how to run a project.
The what and the how
German engineering practice separates two documents, both defined in DIN 69901-5 and VDI 2519. The Lastenheft is written by the customer and states what is required and why — deliberately solution-neutral. The Pflichtenheft is written by the supplier in response and states how it will be built.
The what and the how are different documents, by different authors, in a fixed order, and together they form the contractual basis of the project.
Sewn twice holds better
Sewn twice holds better. A German proverb about redundancy, said approvingly. Alongside auf Nummer sicher gehen, to go on the safe number, and sicher ist sicher, safe is safe — which is a tautology, offered as a reason.
The spare parts store
Das Ersatzteillager. German manufacturers commit to spare parts availability for long periods after a product line ends, and hold the inventory to do it. The obligation extends decades past the sale. The stock is held against a failure that has not occurred in a machine that may already have been scrapped.
The savings rate
Sparquote. German household saving rates run consistently high by international comparison and rose further during periods of uncertainty rather than falling. The reserve grows when it looks most likely to be needed.
Saving before borrowing
Der Bausparvertrag. A German savings contract taken out years before a house is bought: you save to a fixed target, and only then does the loan become available. The instrument requires the saving phase before the borrowing phase. The contingency is built into the sequence.
Insured against everything
Germans carry insurance that has no obvious equivalent elsewhere. Haftpflichtversicherung, personal liability, held by a large majority of households. Rechtsschutzversicherung, legal expenses. Berufsunfähigkeitsversicherung, occupational disability. None of these is compulsory. All of them are normal.
The household stockpile
Vorratshaltung. The German Federal Office of Civil Protection publishes a recommendation that households keep supplies of food and water for a period of days, with a checklist of what and how much. The state issues a stockpiling guide to ordinary citizens as standing advice, not in response to any particular threat.
Buffer time
Buffer time. German project planning builds slack into the schedule itself, allocated to specific stages and carried in the plan. It is not contingency held to one side. It is time that was planned, for events that were not.
