Final answer:
To calculate DEA, divide the number of delivered and attempted packages by the total planned volume. Exclude missing and MNR statuses. The DEA percentage is calculated by multiplying the fraction by 100.
Step-by-step explanation:
DEA stands for Delivery Effectiveness Analysis. To calculate DEA, you need to divide the number of packages that are delivered and attempted (i.e., those with the statuses NSL, UTA, and UTL) by the total planned volume of packages. Missing and MNR statuses should not be considered as attempted.
For example, if there were 1000 packages planned and 870 were delivered and attempted, the DEA would be calculated as:
DEA = (870 / 1000) x 100
DEA = 87%
