A product shortage occurs when the demand for a specific item exceeds its available supply. This situation can arise due to various factors, such as production delays, increased consumer demand, or disruptions in the supply chain. When a shortage happens, consumers may find it difficult to purchase the desired product, leading to frustration and potential price increases. In many cases, product shortages can affect essential goods, like food or medical supplies, as well as non-essential items, such as electronics or clothing. Companies and retailers often respond by adjusting their inventory strategies or increasing production to meet consumer needs and restore balance in the market.
