I have a scenario that im trying to quantify, and wondering if there is a scientific/mathematical way of approaching it. Scenario: Under the previous process when purchasing goods for the values of $0 to $2,000 we were required to obtain one verbal quote. Now under the new process when we purchase goods for the same values we are required to obtain two verbal quotes. Example: Under the previous process one quote was obtained for $1,200, under the new process two quotes were obtained for $1200 and $980 Is there any way to quantify the benefit to the organization by following this new process. As under the previous process it would have cost $1,200 but by seeking another quote it cost $980.
