Asuccessful conversion to a jit system requires that the conversion: no answer selected a - be done as quickly as possible b - begin at the start of the process and work forward c - convert vendors to jit as one of the last steps d - reduce setup times as one of the last steps e - all of the above

Be done as quickly as possible.

Option: (A)

Explanation:

For a JIT system to function efficiently, it is required that the conversion is preplanned entirely. If the conversion is begun to be done with the first step and then done along with the process of manufacturing, it may not yield results as good as conversions done prior to the beginning of the process.Moreover, considering the conversion of vendors as one of the 'last steps' would completely defy the purpose of the JIT System.
