In the business world, making decisions based on a single probable scenario is risky and increasingly so. The market is volatile and uncertain, and customer behavior is unpredictable. This is where the Monte Carlo method comes into play, a statistical technique that allows for the evaluation of multiple possible scenarios before making a strategic decision.<\/p>\n\n\n\n
The Monte Carlo simulation is a mathematical technique that allows analyzing uncertainty and variability in difficult situations by generating thousands or millions of possible scenarios. For example, instead of saying \"next month we will sell 1,200 units,\" the Monte Carlo simulation will generate multiple possible scenarios, taking into account different variables and allowing the margin of error to be reduced.<\/p>\n\n\n\n
It was developed in 1940, during the Manhattan Project. At that time, it was used to evaluate nuclear reactions, but now it is used in numerous disciplines thanks to its benefits. And its name? It is adopted from the famous Monte Carlo casino in Monaco, referring to the fact that it is based on the use of random numbers, just like games of chance.<\/p>\n\n\n\n
In the business context, there are numerous uncertain variables such as future demand, market price, cancellation rate, variable costs, or acquisition cost, among others. With the Monte Carlo method, estimates can be made by incorporating this uncertainty into the model.<\/p>\n\n\n\n
In this way, instead of using a single fixed value, ranges and probability distributions are assigned to the variables. Then, the model will execute numerous combinations showing the probability of each scenario.<\/p>\n\n\n\n
Before seeing the steps to follow, it is important to fully understand the elements that make up this method:<\/p>\n\n\n\n
Now that you understand each one of the elements, we can explain how the Monte Carlo method works. It can be divided into the following steps.<\/p>\n\n\n\n
Finally, we are going to look at a fictional example to understand it better. A company is evaluating launching a new project management tool whose development cost is fixed (500.000\u20ac). In this context, the profitability of its launchment will depend on these input variables:<\/p>\n\n\n\n
Instead of using fixed values, the company establish ranges, meaning that they assign a probability distribution to each variable to be able to use the Monte Carlo system:<\/p>\n\n\n\n
With this, the system executes a thousand fictional launches combining everything in a random way and simulating multiple scenarios. Once this is done, the company analyzes the results to discover how many of these simulations they can lose money. They obtained the next information:<\/p>\n\n\n\n
To sum up, the Monte Carlo method can be very useful to have in mind the uncertainty in your decision-making process.<\/p>\n","protected":false},"excerpt":{"rendered":"
