1076 results about "Root cause" patented technology

A root cause is an initiating cause of either a condition or a causal chain that leads to an outcome or effect of interest. The term denotes the earliest, most basic, 'deepest', cause for a given behavior; most often a fault. The idea is that you can only see an error by its manifest signs. Those signs can be widespread, multitudinous, and convoluted, whereas the root cause leading to them often is a lot simpler.
