In the novel Jurassic Park, the park computer was routinely inventorying the dinosaurs. But the computer system would stop counting once the number it was programmed to tabulate was reached. So the inventory system was biased in a way that would conceal unauthorized breeding in the wild. When the skeptics heard about the system, they removed the bias, and told the computer to count everything. A complete, thorough, and all encompassing audit of dinosaurs on the island. If I recall correctly, the number of dinos on the park was almost double what InGen thought was on the park.
