What is a Learning Curve?


The learning curve theory is that tasks will require less time and resources the more they are performed because of proficiencies gained as the process is learned. The learning curve was first described by psychologist Hermann Ebbinghaus in 1885 and is used as a way to measure production efficiency and to forecast costs. Comparing the two learning rates we have .90 for Wright’s
model and .832 for Crawford’s model. This reinforces the fact that the two
models are not compatible when the same learning rate is used. In other words,
the same set of data will always generate two different learning rates under the
two separate models because unit time and cumulative average time do not
decrease at the same rate.

This learning curve model is only applicable when used to measure the real rate of progress for completing a specific task against time. The task needs to be repeatable, measurable, and consist of only one variable within a procedure; it cannot measure an entire procedure on its own. This is the basis for the learning curve formula, the “Cumulative Average Model” (or “Wright’s Model”), which was described by T.P.

  • Tesla has planned to use the principles behind the learning curve to bring down the costs of their electric vehicles (EVs).
  • Blockchain is a record-keeping technology designed to make it impossible to hack the system or forge the data stored on it, thereby making it secure and immutable.
  • Their results indicated that the optimal switching time is determined by the characteristics of product and process, market factors, and the features of learning curve on this production.
  • Learning and experience curve has a strong dependency on individuals under observation.

He mostly was focusing on memory studies and developed a forgetting curve theory. This theory helps us to understand how our memory works, and retains information, relating to specific things people attempt to learn. If we continue forcing children to “do more school” without addressing the real effects of stress, we will be playing catch-up for years to come. By April 2021, over 61,000 children were hospitalized secondary to COVID-19 infection. Children have also witnessed the toll of illness and job loss on close family members, and have felt the ongoing stress and uncertainty over the past three years. However, a recent report that the U.S. childhood poverty rate more than doubled in 2022 suggests that an alternative approach may be needed.

The other application of learning curve is quantitative, where mathematical models are created to represent the rate of proficiency or mastery of a task. The application can be broad and generalized, such as describing the learning curve involved in learning to read. In these scenarios, a graphical representation using mathematics is not being applied to explain learning progression. The term is therefore used as a qualitative description of learning progression over time. The experience curve theory states that the effort to complete a task should take less time and effort the more the task is done over time. Unit curve is a curve which is plotted using a set of data available for the effort behind production of a single unit.

  • Activities that follow a diminishing returns learning curve are more straightforward when measuring and predicting how the performance and output of the workforce will change over time.
  • Where there is a high percentage of manual labor in a process, the lower the learning curve percent.
  • In the visual representation of a learning curve, a steeper slope indicates initial learning that translates into higher cost savings, and subsequent learnings result in increasingly slower, more difficult cost savings.

Research has shown that as production quantities double over a period of time, the average time decreases by 20% for immediate production unit. The theory of the learning curve or experience1 curve is based
on the simple idea that the time required to perform a task decreases as a
worker gains experience. The basic concept is that the time, or cost, of
performing a task (e.g., producing a unit of output) decreases at a constant
rate as cumulative output doubles. Learning curves are useful for preparing cost
estimates, bidding on special orders, setting labor standards, scheduling labor
requirements, evaluating labor performance, and setting incentive wage rates. Some tasks take a lot of effort initially but are easy to master once the basics have been learned (such as learning to ride a bike). A learning curve is a mathematical concept that graphically depicts how a process is improved over time due to learning and increased proficiency.

For ILT or VILT, roleplay exercises are powerful learning opportunities for boosting retention. He remedied the forgetting curve by reciting and rehearsing over and over again in strategically spaced intervals. Instead of a one-and-done approach, an ongoing, strategic learning program will help learners recall and retain new information for the long haul. Ebbinghaus originally set out to understand why new information that we learn tends to fade away over a period of time. He called it the forgetting curve and created graphs to represent the relationship between time and retention. In particular, the learning curve is a concept that comes up in L&D all of the time—but what does it really mean?

In terms of decision-making, this result means that the employee is performing well, but you need to keep the costs down after the initial plateau. Learning curves can also be applied to organizational performance using either the generalized approach or by conducting a measured analysis. Determining which approach to take depends on whether the desired performance can be directly measured. This model represents a more complex pattern of learning and reflects more extensive tracking. This could be described as a plateau, where the individual is no longer progressing. It could signal that the learner has reached a limit in their ability or that a transition may be occurring.

Example of 80% Learning Curve

The best model is the one that generates time and
cost estimates that are closest to the actual results. The graph above graph describes a situation where a task or activity may be easier to learn, initially resulting in a fast and rapid progression. Activities that follow a diminishing returns learning curve are more straightforward when measuring and predicting how the performance and output of the workforce will change over time. For example, the learning curve can play a fundamental part in understanding production costs and cost per unit.

The learning curve shows that if a task is performed over and over than less time will be required at each iteration. Historically, it has been reported that whenever there has been instanced of double production, the required labor time has decreased by 10 or 15 percent or more. Activities that follow a diminishing returns learning curve are the most straightforward when measuring and predicting how the performance and output of a workforce will change over time. An L&D manager may use this curve problem-6: net present value npv analysis with inflation when developing a training plan to teach their Quality Control team how to use a new reporting tool where the employee only needs to enter the ID number of was tested and the results of each test. In the manufacturing context, the experience curve or learning curve refers to the way in which the efficiency of processes increases over time as the units are produced. The learning rate or learning curve coefficient refers to the amount of money that is saved every time production is doubled.

However, if the rest of the data shows that the task should not take very long for employees to learn, this graph is taken as an indication to modify your employee training method. This means that every time we double the cumulative quantity, the process becomes 20% more efficient. The learning curve also is referred to as the experience curve, the cost curve, the efficiency curve, or the productivity curve.

Learning Theories

The cumulative total hours for 8 units is 409.6 based on Wright’s
model and 534.6 based on Crawford’s model. Another difference is that the
cumulative average hours and cost decrease by a variable rate in Crawford’s
model. This does not present a problem when using Crawford’s model because the
cumulative averages are not required for predicting cost. These are often highly complex tasks or require higher degrees of creative or strategic thought. Performance may increase steadily at the beginning before reaching a plateau once learners have mastered the basics.

Efficiency and development curves typically follow a two-phase process of first bigger steps corresponding to finding things easier, followed by smaller steps of finding things more difficult. It reflects bursts of learning following breakthroughs that make learning easier followed by meeting constraints that make learning ever harder, perhaps toward a point of cessation. We have strategies for supporting children through stressful situations—strategies known to calm the downstairs brain and allow the upstairs brain to function again. Increasing academic demands and accountability only serves to exacerbate stress, thereby keeping the downstairs brain activated. Indeed, if we truly want to mitigate learning loss for all children, then the solution lies in doing the exact opposite of what we are seeing in most public education systems. However, when a child experiences prolonged stress or trauma, the child’s downstairs brain remains in hypervigilant mode even after the experience is over, causing negative short and long-term effects on learning.

This means that if you are unaware that a technology follows Wright’s Law, you can get your predictions very wrong. From their initial niche computers expanded to more and more applications, and the virtuous cycle meant that the price of computers declined continuously. The exponential progress of computer technology expanded their use from a tiny niche to the defining technology of our time. More of that technology gets deployed to satisfy increasing demand, leading to falling prices.
