Experience curve effect

The more you do a task, the faster you can do it. This is called a learning curve. Long ago, a man found that practice helps people learn. Later, an engineer found that making many things helps lower costs. Every time a company makes twice as many items, the cost goes down. This happens because workers get better at their jobs. They learn how to avoid mistakes. Making things also gets easier with better tools.

The more you do a task, the faster you can do it. This is called a learning curve. In 1885, a man named Hermann Ebbinghaus studied this. He found that practice helps people learn words. Later, an engineer named Theodore Paul Wright found a new link. In 1936, he studied how planes were made. He saw that making twice as many planes cut labor time by 20 percent. This is often called Wright's law.

Companies also use this idea to save money. This is called the experience curve. Bruce D. Henderson used this name in the 1960s. He saw that costs drop as a company makes more goods. This happens for many reasons. Workers get better at their jobs. They make fewer mistakes. Companies also get better tools and better ways to work.

Lower costs can help a company grow. They can sell things for less money. This helps them win more customers. For example, solar panel prices drop as more are made. This helps more people use solar power.

The experience curve effect explains how doing something many times makes it easier and cheaper. It is a way to show how learning helps people and companies work better. When a group makes more of a product, they often find better ways to do it. This helps them save time and money. This effect is very important for businesses. It can help a company grow much larger than its rivals.

This effect works through several different steps. First, workers become more skilled at their specific jobs. They learn shortcuts and make fewer mistakes as they practice. Next, companies often use better tools or new technology. They might also change how a product is designed to make it easier to build. Even the way parts are organized can change. All these small improvements add up to big savings over time.

People have studied these patterns for a long time. In 1885, a German psychologist named Hermann Ebbinghaus studied how people memorize words. He found that practice helped people perform better. Later, in 1936, an engineer named Theodore Paul Wright studied airplane production in the United States. He discovered that every time the total number of planes doubled, the labor time fell by 20 percent. This discovery is known as Wright's law.

In the 1960s, Bruce D. Henderson used a new name for this idea. He founded the Boston Consulting Group and called it the experience curve. He noticed that costs often dropped by a set percentage every time production doubled. For example, a curve with a 15 percent reduction is called an "85% experience curve." Different industries have different rates. NASA found that aerospace costs might drop by 15 percent per doubling. However, repetitive electronics manufacturing might only see a 5 to 10 percent drop.

This idea connects to how we use technology every day. Think about how much easier it is to use email because so many people have accounts. As more people join a network, the whole system becomes more useful. You can also see this in the price of solar panels. As more solar capacity is installed around the world, the price of the panels drops. This allows more people to use clean energy. Learning from the past helps us build a more efficient future.

The experience curve effect describes how efficiency improves through repeated activity. It is a model used to show the relationship between production experience and cost reduction. As a company produces more of a good or service, the cost of each unit typically drops. This effect has massive implications for market share and competitive advantage. Companies that learn faster can often dominate their industries by offering lower prices.

The mechanism of this effect involves several interconnected processes. First, labor efficiency increases as workers become more dexterous. They gain mental confidence and spend less time hesitating or making mistakes. Second, companies often implement standardization and specialization. When employees focus on a limited set of tasks, they operate at a much faster rate. Third, technology-driven learning occurs as new automated systems are implemented. Finally, manufacturers often use product redesign to simplify the making of a good. This might include removing features that do not work well or adding parts that make assembly easier.

There are different ways to view these mathematical patterns. One common version is known as Wright's law. This law focuses on the relationship between cumulative production and labor time. Another version is the experience curve, a term used to describe broader cost behavior. While the learning curve focuses on production tasks, the experience curve includes administration, marketing, and distribution. These are often expressed as a power function. The math uses a progress ratio to predict how costs change. For example, an industry might have an "85% experience curve." This means costs drop by 15 percent every time the total output doubles.

The history of these ideas began with psychological research. In 1885, German psychologist Hermann Ebbinghaus studied verbal memory. He found that performance increased as people practiced with word sets. In 1936, an engineer named Theodore Paul Wright applied these ideas to industry. While working at Curtiss-Wright in the United States, he studied aircraft production. He discovered that labor time fell by 20 percent every time total production doubled. Later, in the 1960s, Bruce D. Henderson of the Boston Consulting Group (BCG) expanded this concept. He analyzed the semiconductor industry and found that prices often declined at a constant rate. He suggested that market share was a key driver for these savings.

Different industries show different rates of improvement. NASA has provided specific examples of these progress ratios. In the aerospace industry, the ratio is often around 85 percent. Shipbuilding shows a ratio between 80 and 85 percent. For repetitive tasks like electronics manufacturing, the ratio is higher, between 90 and 95 percent. Even raw materials show a high ratio of 93 to 96 percent. These numbers show that some industries learn much faster than others. These specific rates help companies plan their long-term investments and pricing strategies.

There are also moments when these curves change suddenly. These are called experience curve discontinuities. A curve might be truncated when a company must upgrade its technology to stay competitive. This happens when competitors introduce entirely new processes. It can also happen when a major technological change makes old methods obsolete. When a firm upgrades, the old curve is replaced by a new one. This forces companies to constantly re-evaluate their strategies to avoid falling behind. If a company fails to show these learning effects, it faces a significant business risk.

The experience curve connects to many broader economic ideas. It is closely related to economies of scale, which are efficiencies gained from large-scale production. Some experts, like Ernst R. Berndt, argue the two are almost impossible to separate. It also connects to network effects, where a product becomes more useful as more people use it. For instance, email becomes more efficient as more accounts are created. Finally, the effect relates to strategic management. Companies use these insights to decide whether to enter a market or exit a business to focus on more profitable areas.
