M&E plan

A monitoring and evaluation plan is a comprehensive planning document for all monitoring and evaluation activities within a program. This plan documents the key M&E questions to be addressed: what indicators will be chosen, how often and where will the data be collected, what are the baseline values and what will be the targets values, how will the data be analysed and interpreted, and to whom and how often will reports be developed and distributed.

Minimum reorder level

The minimum reorder level (MRL) is the minimum stock quantity that should be available at all times and indicates when a request for additional stock must be placed. It is also known as re-order point and triggers an action by the store personnel to submit a requisition to replenish the stock. The MRL is usually determined based on consumption pattern and lead time. 

MRL = (Average monthly consumption * lead time in months) + buffer stock

If you use lead time in weeks, then your average consumption should also be in weeks.
