Commonly used inventory performance measures

Inventory Turnover: Inventory turnover is a key metric used to evaluate the efficiency of an organization’s inventory management system. It measures how quickly the company can move through its stock as compared to sales or demand. There are two factors that impact this ratio – average cost per unit and annual sales volume over a period of time (usually one year). The higher the number indicates better performance as it means the company is selling more product without having too much excess or obsolete inventory on hand at any given time. The ideal target should be somewhere in between 20-40; if you’re below then you might have too much stock sitting on shelves while if you’re above 40 then you might be losing out on potential revenue due to understocking products customers want. Days Of Supply (DOS): Days of supply reflects how many days' worth of stock a company holds in its warehouse at any point in time based upon current levels of usage and lead times from suppliers. It helps businesses understand if they have enough stock available for customer orders and whether there could potentially be gaps between available supply and future demand based off historical trends or current projections. A healthy DOS number will be anywhere from 20-50 days which gives them enough time for new replenishment orders but also doesn't let them carry excessively large amounts which would tie up capital unnecessarily since typically unused material has little value beyond just taking up space in storage facilities/warehouses . This metric is especially useful when dealing with seasonal/fluctuating demands because it allows companies to anticipate future needs before running out completely or overfilling warehouses unnecessarily so they don't get stuck with deadstock they can't sell later down the line either due to age/demand changes etc… Service Level: Service level measurements look at things like customer satisfaction with availability, delivery times, fill rates etc… The goal here is essentially make sure everything outside your internal systems (supply chain partners, retail stores etc…) meets customer expectations while still maintaining profitability margins within your business model itself - essentially getting things done right without breaking too much financially speaking! Companies may use metrics such as percentage availability rate or percent fill rate success when looking at these types of calculations; essentially trying determine what impact does not having certain items readily available during peak times have versus those same products being ready ahead schedule? Achieving high scores across these indicators therefore often requires quite robust planning processes backed by modern technologies & agile procedures that allow businesses flexibility adapt changes quickly & accurately as needed throughout course of day/week/year etc… All together these three measurements help give executives visibility into their overall operations health, allowing them identify where improvements need made maximize profits & efficiency by making sure stockpiles aren't too big leading capital tied up costs, nor too small causing missed opportunities due increased outages / delays caused by lack resources necessary satisfy customer requests timely fashion both now future alike! Furthermore combining data gathered each individual measurement gives better picture whole system's performance opposed isolated view points taken singularly; thus providing more holistic understanding exactly what going wrong fixing areas concern ITEM BY ITEM basis before bigger problems arise down road due lack foresight predicted upcoming issues demanded scenario(s).
