Enterprise resource planning, or ERP, became popular among larger manufacturers in the mid- to late-1990s, with companies around the world investing approximately $300 billion in the systems during the decade. Enterprise resource planning involves using technology to coordinate the activities that take place in different areas of your business. In other words, ERP software facilitates the sharing of information between departments so that your business runs more efficiently and better decisions can be made at all levels of your organization.

Changes in the Apparel Industry

When ERP technology was first introduced, interest in it was largely limited to large corporations because of the cost involved. Over time, ERP technology has become more affordable and the systems have become easier to implement, which has made them increasingly attractive to businesses of all sizes, including organizations with limited budgets.

In a report entitled, “A Guide for a Successful ERP Strategy in the Midmarket: Selection, Services, and Integration,” Aberdeen Group estimates that 84 percent of midsize businesses have implemented ERP software in their operations. While an increasing number of companies have an ERP system, Murray Mitchell, Global Leader, General Business, Global Business Services at IBM doesn’t think enough businesses use their system to its full potential. According to Mitchell, companies that view the implementation of an ERP system as an opportunity to transform their operations instead of a simple change in technology are better prepared to get the most out of their systems.

Just as an ERP system can be useful in other industries, the technology can be particularly beneficial to businesses in the fast-changing apparel industry. One area in which an ERP system can be quite useful is helping you figure out how to forecast demand in the apparel industry.

Over the past 20 years, the apparel industry has undergone significant changes that have made it more difficult for many businesses to accurately forecast demand for their products. For people outside of the fashion industry, there are typically four seasons per year: summer, fall, winter, and spring. When it comes to the apparel business, however, many industry insiders typically created a retail calendar that includes more seasons in recent years. For Zara, a fashion retailer that sells textiles for men, women and children, a single year may have as many as 20 distinct seasons.

In addition to having more, and shorter, selling seasons, the apparel industry has undergone other meaningful changes over the past two decades, which include:

  • Outsourcing: In recent years, many companies in the apparel industry moved their manufacturing offshore to locations with lower labor costs to reduce their production costs.
  • Longer Lead Times: Much manufacturing is done elsewhere, so retailers now need longer lead times to acquire the goods they’re going to sell.
  • Technology: ERP systems enable retailers to run their operations more efficiently, but the systems also allow them to work better with their suppliers because the technology can be integrated with the systems their vendors use. If you decide to extend you ERP system to your suppliers with technology such as a Vendor Portal system, suppliers can review your purchase orders online and can provide up to date status on P/O lines. Suppliers can create also ASN’s (Advance Shipment Notice) and they are immediately available in the ERP system, and upon completion of the ASN carton labels can be created automatically or via the carton label program both with SSCC18 numbers all improving efficiencies for both the supplier and your company.

In addition to facilitating communication between your company’s departments and your business and its vendors, ERP software enables you to improve the way you interact with your customers. ERP technology tracks the products in your inventory from receiving through delivery to your clients in real-time. You can respond to inquiries about orders quickly and accurately and increase the confidence consumers have in your company.

Technological advances clearly changed the way many organizations in the apparel industry conduct business, and it also changed the way people shop for goods. Over the past two decades, e-commerce has become increasingly popular, especially for members of younger generations, such as Millennials. Technology has given consumers a vast number of online stores to choose from, and it has also given them instantaneous access to new fashion trends and brands. Shoppers are now more fashion-conscious, which has altered their requirements when making purchasing decisions.

  • Less Mass Production: To better satisfy consumers’ changing requirements and to stay current with the additional fashion seasons, many companies moved away from mass producing apparel over the past two decades. Instead of mass producing their products, many companies focus on developing new, fresh clothing that shoppers will find attractive.

How to Improve Forecasting in the Apparel Industry

One essential element of forecasting is understanding how to use it to your advantage. By nature, human errors are inevitable — even with ample research, no prediction is guaranteed to be perfect. However, overall accuracy is an important factor, as fashion life cycles are relatively short-lived. 

1. Collect a Detailed History

With reliable predictions about the potential for future demand, your company can find future successes among your consumers. The forecasting process can provide you with an excellent basis for making informed decisions about how to move forward.

While apparel forecasting is a challenging task, there are several steps you can use to improve your forecasting process:

2. Identify Aesthetics

After you have a sufficient baseline of information, you can go into even more specific detail. Identify the attributes of your various clothing and fashion items, focusing on any possible factors that may affect what your customers purchase. You may be able to find trends in specific designs, colors, cuts and more.

Through discussing and analyzing aesthetics, you can create macro and micro trends. Each is set to different timelines, with macro trends forecasting well in advance and micro trends occupying a much shorter time frame. These scopes will drive your design teams for several years in advance. 

As far as aesthetics goes, you can include a wide variety of detail, including:

  • Fabric
  • Color
  • Cut
  • Neckline
  • Collar style
  • Sleeve style
  • Cuff style
  • Pockets
  • Pleating
  • Design placement

This information will help you find critical features that drive your sales and various fashion trends. 

3. Create Average Forecasts

While it’s best to get as close as possible with the information you have, it’s also essential to address the possibility of error and leave room for it in your calculations. You can also tailor your buying strategies to suit the margin of error you expect. 

Taking averages and creating forecast combinations based on your collected data will make the information more accessible and readable. You can create graphic representations of your analysis, showing patterns in an easily visible layout and simplifying them for presenting to other parties. You should do the same for your sales history, and tag specific items you sell that share the stand-out characteristics. 

When it comes to your forecasts, you should explore multiple avenues. Since you’re making an educated prediction, there are often several possibilities for how the trends can play out in the future. Rather than creating a single forecast, you should take the averages of several predictions and create a potential trajectory based on multiple patterns. 

You can also choose to focus on short-term or long-term forecasting or to implement both in different ways. For some companies, fast pacing is more important than accuracy, and vice versa. Short-term predictions focus on fast trends and keeping up to date with how the market is currently shifting, with an emphasis on speed. Long-term forecasting involves a deeper understanding of fashion and information analysis based on collected data. It’ll also provide you with better accuracy.

It’s important to decide what’s best for your company and how you want to forecast before collecting data and conducting analyses. You can choose to opt for speed and quick trends or accuracy on long-term predictions. The latter provides you with a significant amount of time to implement your forecasting, while the former doesn’t. 

4. Pay Attention to Ability

When you have multiple people responsible for forecasting, you may see varying results among them. While it is best to take the averages of their predictions, you should also make it a point to evaluate each forecaster independently, rather than as a group. Tracking your forecasters will allow you to follow their accuracy over time. 

If you notice some performing better than others, you are justified in taking their predictions into account as a more significant part of your forecasting. Consistent accuracy is an excellent reason to give their predictions more weight, as they may improve your forecasting overall. 

5. Adjust Forecasts

While your projections are based on significant data and historical trends, you can improve them over time. As you implement your forecasting and see your first round of sales, use the data from your first week to adjust your forecasts. Once you make changes, you can continue to tweak your predictions in the future and for the current trends based on how your insights and performance contrast with one another. Continual adjustments will help you improve your inventory management in later forecasting.

How to Forecast Supply Chain in Apparel

The changes that have taken place over the past 20 years have made forecasting in the apparel industry more difficult. The consumer demand in the industry itself involves some intrinsic attributes that have always made forecasting accurately a challenge. When it comes to apparel, many consumers buy goods based on an impulse, for instance. Shoppers often wait until the point of purchase to decide that they’re going to purchase a particular item. It’s critical to forecast your sales and inventory needs as accurately as possible, so you won’t miss sales due to a lack of product supply.

Consumer demand in the apparel industry also has the following characteristics:

  • High Volatility: Demand for apparel is highly volatile, which stems from numerous factors, including the weather, pop culture, sports figures, and the economy, among many additional influences. If your suppliers fail to deliver goods in a timely manner, their unreliability can also create volatility in your supply chain.
  • Low Predictability: Given the volatility inherent in the industry’s consumer demand, it can be nearly impossible to predict how many units you’ll sell in a given period of time. Even if you can forecast the total number of sales you expect to record over a certain time period, it can be difficult to accurately forecast the number of each item included in your inventory that you will actually sell. While you may expect to sell 10,000 shirts in January, for example, you may not be able to accurately predict which of the 100 styles of shirts you sell will be your biggest seller in that month.
  • More Variety: As more and more options have been made available to consumers, the demand for apparel products has become increasingly fragmented through the years. Consumers are more aware of their options, and they’re more concerned about the quality of the goods they’re buying because they have plenty of choices.

It’s challenging to forecast the future demand for your apparel products, but it’s not impossible. Demand forecasting involves using the information you have at your disposal to determine the amount of product you’re going to need to satisfy your customers’ needs and when you’ll need to have it in stock. It’s even more difficult in the apparel industry because new products are constantly introduced. If you introduce new items every year or fashion season, you may not have the historical data necessary to figure out how much of a new product you should have in your inventory.

If you have an ERP system, you can use the sales history of similar items to help you forecast the demand for a new item. You can also use your system to track the number of new products you sell in the first few weeks or days that the item is offered, and use that data to figure out how many more units you’ll need to meet demand.

Sales forecasting also attempts to determine the future demand for your products within a given set of circumstances. To create an accurate sales forecast, you’ll typically need three types of information:

  • Internal Data: You need data about your historical sales volume, as well as information about your current marketing promotions and advertising activities.
  • Future Information: You also need to be familiar with your company’s marketing plans for the future and how your products will be distributed as you move forward.
  • External Data: You need to be knowledgeable about the state of the market and your suppliers’ access to the raw materials they need to manufacture the goods you sell. You also need to be aware of the overall political, economic and cultural environment in which you compete.

The particular forecasting method you’ll use will depend on various factors, including the type of information that’s available to you. No matter which technique you decide to use, you’ll need to measure your forecast’s accuracy so you can more finely tune your future forecasts. An inaccurate sales forecast can have expensive consequences, including missed sales opportunities caused by product outages and an overburden of unsalable inventory.

In simple terms, forecast accuracy is the difference between the sales volume you predicted and the sales numbers you actually record. While your overall demand forecast may be fairly accurate, studies have shown that the forecasts for individual SKUs are often off by as much as 35-50 percent and that they can be off by as much as 100 percent in some cases. Only looking at the difference between your forecasted and actual sales is normally not enough to determine the accuracy of your forecasts. Positive and negative errors typically offset one another, which generally makes a forecast appear more accurate than it really is.

For this reason, many businesses in the apparel industry use mean absolute percentage error, or MAPE, to measure the accuracy of their demand forecasts. MAPE is calculated by dividing the absolute value of the difference between your forecasted and actual sales, dividing the result by your actual sales, and multiplying the result by 100.
