Time Series Analysis > Exponential Smoothing, Contents: The first thing you want to do is grab your historical data, and calculate period-by-period growth rates in call volumes. In some cases, the Holt-Winters algorithm gives better results than the ARIMA and in others cases it is the other way around. Your email address will not be published. Even with the best workforce management plan in place, your service level is always going to better on some days than others. However, the number of calls youre going to be making might be unpredictable or seasonal. The more complex the series then the more nodes you will need, says Nikos Kourentzes. More recent observations given larger weights by exponential smoothing methods, and the weights decrease exponentially as the observations become more distant. Meaning, 75-80% of calls are answered within 30 seconds, in terms of an average each month. First, you need to define the duration of your forecast. Perhaps one of the most confusing aspects of exponential smoothing is the damping factor. The easiest way to create exponential smoothing in Excel is to use the Data Analysis Toolpak.

However, with the right approach, youll be able to make much more accurate forecasts, helping you maximise efficiency while avoiding understaffing as much as possible. For more information on how neural networks work I would recommend reading Steven Millers article on How to Build a Neural Network. This should include everything from the start of the call to the point when the agent has finished wrapping (their post-call tasks). Forecasting is useful for many scenarios like preventive maintenance, resource planning, and more. This is a method to combine both high-frequency data (hourly daily, weekly) with longer-term trends over time. Heres how double exponential smoothing works in practice. The big danger is tit is very easy to over-fit the data, so that if there are any anomalies in the historical volumes, such as outages or peaks in demand, these can result in very odd-looking forecasts. Spreadsheets were developed as computerized analogs of paper accounting worksheets. dimension of output grid in y direction. Below, well explain more of the actual methodology of call centre forecasting. The forecast keeps up with the growth rate a lot better. Your first 30 minutes with a Chegg tutor is free! Despite accounting for trends, the double exponential method still fails to account for seasonality. ALL RIGHTS RESERVED. However, there are some problems with this technique: To solve the first problem with the aforementioned method, we can use a technique known as exponential smoothing. According to Brian ODonnell posting on Stack Exchange, I have seen people with different data sets compare results from both algorithms and get different results. Changing alpha will influence the mean squared error. Weibull, exponential, and Gompertz models; smoothing; bootstrapping; nonparametric regression; In this method, members from all levels of a business come together to make a forecast. The TREND function works exactly the same in Google Sheets as in Excel. Average handle times. Here is how the Single Exponential Smoothing calculation can be explained with given input values -> 40 = (0.2*44)+((1-0.2)*39).
