Single Point of Failure
Also known as: SPOF, bottleneck risk, key-person dependency, no redundancy
Any single component — a person, system, supplier, or process — whose failure would halt the entire business, because no backup or redundancy exists. In founder-owned companies, that component is usually the founder.
WHY IT MATTERS
A single point of failure is any one component a system depends on so completely that its failure brings the whole thing down — no redundancy, no backup, no alternative path. The term comes from engineering and IT (a lone server, a single power supply), but it applies to any business resource: a sole supplier, an undocumented process, a single piece of equipment, or one person. In founder-owned companies, the founder is almost always the biggest one — only one person knows the pricing model, holds the largest customer relationship, or can approve a purchase order. When the buyer’s diligence team maps the business and finds critical functions with no redundancy, each one becomes a line item on the deduction list — something that stops working the day that component is unavailable. The fix is redundancy: documentation, delegation, cross-training, and backup suppliers and systems, so the business runs whether or not any single component is in place.
