XPkäyriä

XPkäyriä, often translated as "XP curves" or "experience curves," is a concept in business strategy that describes the relationship between cumulative production and the cost per unit of a product. The core idea is that as a company produces more of a particular product, its costs tend to decrease. This phenomenon is not solely due to economies of scale, but also to learning effects and technological advancements that occur as production volume increases.

The experience curve suggests that for every doubling of cumulative production, costs typically fall by a predictable percentage, often in the range of 10% to 30%. This decrease in cost can be attributed to several factors. First, learning by doing leads to improvements in efficiency and productivity as workers become more skilled and processes are refined. Second, technological advancements are often spurred by the need to reduce costs and improve performance at higher volumes. Finally, changes in product or service design may occur over time to simplify manufacturing or assembly, further contributing to cost reduction.

The concept was popularized by the Boston Consulting Group (BCG) in the late 1960s and early 1970s. It has been used as a strategic tool to understand competitive advantages, pricing strategies, and market share dynamics. Companies that can achieve higher cumulative production volumes than their competitors may enjoy a significant cost advantage, enabling them to price more aggressively and gain market share. Conversely, companies with lower volumes may find themselves at a cost disadvantage. While the exact percentage of cost reduction can vary by industry and product, the underlying principle of cost decrease with cumulative experience remains a significant factor in strategic decision-making.
