What Is Learning Curve Theory?

Perfecting things becomes ever more difficult despite increasing effort despite continuing positive, if ever diminishing, results. The same kind of slowing progress due to complications in learning also appears in the limits of useful technologies and of profitable markets applying to product life cycle management and software development cycles). Remaining market segments or remaining potential efficiencies or efficiencies are found in successively less convenient forms.

You will learn things faster initially, but progress decreases as you become more familiar with the subject matter. This suggests that the task being measured is challenging to learn and takes a certain amount of practice before an employee becomes proficient. If the plateau is closer to the X-axis, it represents a highly efficient performance. On the other hand, if the plateau is closer to the top half of the graph, performance may not be as efficient.

  • The learning curve helps the employees to become more efficient, and this increases production.
  • The theory was first popularised by Theodore Paul Wright in 1936 for the aircraft industry to describe how each unit of production required less effort than the previous one.
  • People should remember that these graphs are representational of an average rate of knowledge gained over time.

The cumulative average
hours and cost as well as cumulative total hours and cost are provided below for
doubled quantities 1 through 8. The complex learning curve model will look different for each activity and potentially each individual or group. Learners will encounter multiple peaks and plateaus when learning tasks with complex learning curves.

On a logarithmic axis, a measure that declines exponentially follows a straight line. Hitesh Bhasin is the CEO of Marketing91 and has over a decade of experience in the marketing field.

The third curve is an integration of both concave and convex curves and hence is known as a concave-convex curve.

Increasing-Decreasing Return Learning Curve (the S-curve)

This inflexibility can be a disadvantage in rapidly changing industries where adaptability is key. Furthermore, a strong focus on current processes and efficiencies might discourage exploration of potentially more effective methods or technologies, leading to a stagnation in innovation. This type of learning curve may be encountered when a new productivity tool is introduced to employees.

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. The concave learning curve is also famous fun facts: products we get from beef cattle by the name positively accelerated curve. It depicts slow improvement at the onset with the learning increasing with time to show mastery. The rate of progress is thus slow at the beginning but picks up, and the final learning rate shows a noticeable increase.

More meanings of learning curve

It demonstrates that productivity increases over a while but with a diminishing rate as production increases. This means
that the cumulative total time would not increase because it would equal 100% of
the previous cumulative total time. Notice from Table 2 that the unit labor hours (column 2) and
unit labor cost (column 4) decrease by 20% each time the cumulative output is
doubled. However, the cumulative total labor hours (column 3) and cumulative
total labor cost (column 5) increase by a variable rate. It also means that the cumulative
total hours and cost generated by the two models are not compatible when based
on the same learning rate.

Understanding a Learning Curve

The learning curve theory puts its onus on the fact that when a new activity commences, the engaged workforce will not be able to achieve maximum efficiency at the beginning. Repetition of tasks will give the necessary confidence to gain knowledge that will enable quick and effective operations. As a result, the time taken to complete the task will decline and later stabilize after achieving an efficient working.

This is contrary to a flatter curve, where progress is more gradual and easier to achieve. The term “steep learning curve” is often used to describe situations where the learning process is challenging or complex. In this context, “steep” implies that a significant effort and time-frame are needed to make real progress. The equations provided above show how to use the learning
curve to predict the time and cost of a specific quantity of units assuming that
we know the learning rate.

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. It is our common belief that people and organizations become more efficient over time.

What is the learning curve?

If your skills plateau and you feel like you need to progress more quickly than you’d like, realize that this is normal and that it doesn’t mean your learning curve has flatlined. Whatfix’s DAP empowers organizations with a no-code editor to create in-app guided flows, onboarding tasklists, pop-ups, tooltips, alerts, reminders, self-help wikis, and more to enable employees to use software better. Here are 8 effective tips for organizations to use the learning curve for designing effective employee training programs. In the increasing-returns curve, the rate of progression is slow at the start and rises over time until full proficiency is achieved.

The model was widely applied during World War II (WWII) when it was realized that the cost of aircraft decreased with the increase in production performance. It was later taken up by the industrial and business sector for a variety of performance improvement applications. Measured
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.

Diminishing-Returns Learning Curve

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. A learning curve is a mathematical concept that graphically depicts how a process is improved over time due to learning and increased proficiency.
