Just In Time Production or Lean Production systems focus on the efficient delivery of products or services. Some of the distinguishing elements of the JIT systems are a pull method to manage material flow, consistently high quantity, small lot sizes, uniform work station loads. The JIT systems provide an organizational structure for improved supplier coordination by integrating the logistics, production and purchasing processes. When Operations Manager focuses on their organization’s competitive advantage they aim for low cost of production, consistent quality with reductions in inventory, space requirements, paperwork and increases in productivity, employee participation and effectiveness.

Why should we, as computing professionals, be interested in studying the social implications of our creations?

  • Computing technology has changed our way of life like no other technology
  • We need to study how it has done it to highlight the mistakes and success stories of the past
  • We need to do it so that we can learn from them and select our future direction accordingly
