Supply Chain Management

Quantification and Programming

Quantification and programming are phases of the logistics cycle that occur before procurement, but after product selection. Quantification involves both forecasting and supply planning. The efficiency of a supply chain relies on forecasts to determine the demand and procurement needs for a specific medicines, products, and health supplies. Accurate forecasts ensure programs have enough supplies to serve their users and avoid stock-outs. In documents within the toolkit, the terms programming and quantification are sometimes used interchangeably.

Quantification answers the question: “How much will be procured and when will it be delivered?”. It is the process of estimating the quantities and costs of the products required for a specific health program (or service) and for determining when the products should be delivered to ensure an uninterrupted supply for the program. It considers the expected demand for commodities, unit costs, existing stocks, the stock already on order, expiring products, freight, logistics and other costs, lead times, and buffer stocks. Using this information, the total commodity requirements and costs are calculated and compared with the available financial resources to determine the final quantities to procure. The procurement process is discussed in the next module.  

Forecasting answers the question: “How much is needed, in quantities and cost, to meet the health demand of the population?” It is the process of estimating the expected consumption of commodities based on historical consumption, service statistics, morbidity and/or demographic data or assumptions when data are unavailable, to calculate the quantities of commodities needed to meet demand during a particular time frame.

Supply planning refers to the quantities required to fill the supply pipeline, costs, lead times, and arrival dates of shipments to ensure optimal procurement and delivery schedules. Supply planning is considered the final output of quantification.

This section of the toolkit provides several forecasting and programming guides that can be used to project supply needs. The toolkits focus on reproductive health commodities, as well as preventative health care commodities that address the leading causes of morbidity in Latin America and the Caribbean (LAC). The toolkit also includes programmatic guides for laboratory and pathology supplies and commodities. The materials include examples from various countries in Central America.
