A procedural failure is defined as a nonphysical factor contributing to failure, such as error.  Procedural failures are most important when determining who is liable or responsible for the failure.  For example, if a part or plant is assembled and later fails, one must determine the cause of said failure whether it be during the method of assembly or if something was manufactured wrong.

A failure at a nuclear power plant was blamed from “procedural and hardware” failures.  24 radioactive rods were dropped while being moved during the assembly process.   This may be deemed as a procedural failure because the cause of the accident was due to something going wrong during the assembly process.  Although no injuries were reported, extra safety precautions have now been put in order to prevent failures like this from occurring.  [A]

Another example of a procedural failure happened at an elementary school. Signs of distress n the concrete formed very early including building wall movements, cracking of finishes, and slab heave.  These issues were reported and legal action was taken by the school to figure out the cause of the problem.  Expansive soil problems related to pyrite were deemed to be the cause of failure.  Because the original soil and land survey was performed poorly, this caused damage for over 40 years to the building.  Multiple repairs, cosmetic and structural, have been made by the school.  [B]
