• Benefits of Buffering the Transformation Process–The process was not disturbed by
environmental interaction.–The process was often more efficient than input
and distribution processes.–Productivity was maximized when processes
operated at continuous rates.–Process management skills were different from
those of other functional activities.

• Disadvantages of Buffering the Transformation Process–Information lag in interaction with other
functional activities.–Lack of communication between customers and
the shop floor for problem solving.
• Value Chain–Steps an organization requires to produce a
good or a service regardless of where they are performed.
