What is the importance of statistics in the field of engineering?

To be able to keep parameters within a controlled process. For ISO certifications and process verifications. To follow guidelines set forth by criteria standards. To display what occurs given certain conditions. # Design of Experiments (DOE) uses statistical techniques to test and construct models of engineering components and systems. # Quality control and process control use statistics as a tool to manage conformance to specifications of manufacturing processes and their products. # Time and methods engineering uses statistics to study repetitive operations in manufacturing in order to set standards and find optimum (in some sense) manufacturing procedures. # Reliability engineering uses statistics to measures the ability of a system to perform for its intended function (and time) and has tools for improving performance. # Probabilistic design uses statistics in the use of probability in product and system design.
