Standard Work: Standard work lists the normal tasks done with the least amount of waste possible at the current time (of course, it will continually be improved.) Standard work includes the amount of time needed for each task. Standard work focuses on the employee, not the equipment or the materials. Standard work is completed by the actual operator performing the task since they know best the details of the process. Standard work is often confused with work standards and/or work instructions. They are not the same thing. Standard work reduces variation an increases consistency that is necessary for first-time quality.
Of the two, lateral dynamics has proven to be the more complicated, requiring three-dimensional , multibody dynamic analysis with at least two generalized coordinates to analyze. At a minimum, two coupled, second-order differential equations are required to capture the principal motions.  Exact solutions are not possible, and numerical methods must be used instead.  Competing theories of how bikes balance can still be found in print and online. On the other hand, as shown in later sections, much longitudinal dynamic analysis can be accomplished simply with planar kinetics and just one coordinate.
