Productivity is often thought to be about working harder or faster and historically was linked with time and motion. In reality, productivity is about making the work easier, quicker; it’s about finding better and more consistent methods that will reduce work content. In so many cases it’s about better organisation.
Productivity is about making better use of resources and, at many different levels, compares output/input. When using time measures, output is the work content. and input is attendance hours.
