Calcite Efficient Process

4 Types of Process Efficiency

Process efficiency is the output of a business process for a unit of input Processes are often repeatable aspects of a business that can be heavily optimized to improve efficiency The following are common types of process efficiency Overall The overall efficiency of a process is the value of outputs divided by the value of inputs For example a production line that takes inputs of $1
