Critical Thinking


Operations Management. Williams J. Stevenson.

Nature is always our best mentor.

The photo illustration was chosen because the stream symbolizes the flow of work through the
system. An important goal for operations systems is to achieve a smooth flow of work through the system. And just as rocks in the stream on the photo disrupt the smooth flow of water and causes turbulence, inefficiencies, variability, and uncertainties in operations systems cause problems that disrupt the smooth flow of work through the system, increasing time and cost, and decreasing  productivity and customer service.The flow concept applies not only organizations, but also to their supply chains.

Atmospheric Entry

Simulation of Space Shuttle Atmospheric Re-Entry.
High speed in space are not the problem, there's no atmosphere. But start hitting trillions of of tiny particles in the upper atmosphere which created much friction  and generated extremely heat.
