A potential customer has a problem; he typically orders perishable items every two weeks base on historical metrics. However, in the last few years, many times his estimates have been very inaccurate; in soma cases he ran out of stock and thus lost sales, in other cases he didn't sell all of the items, which had to be destroyed resulting in losses. Describe how you would resolve his problem, identify the best PMLC methodology to implement your solution, and specify the contract type you (as the project lead, who would conceive and implement a solution) would propose. Be very specific and be sure to answer all parts of this question.
