Demand Planning in Logistics

What is the role of demand planning in logistics?

First of all, let’s define what is demand planning.
Demand planning represents a set of methodologies and information technologies for the use of demand forecasts in the process of planning. The aim is to accelerate the flow of raw materials, materials and services beginning with the suppliers through transforming to products in the company and to their distribution to their final consumers.1

Fashion demand is highly unpredictable due to their short life cycles which are typically just a few months. Is because of that the demand planning becomes an important aspect in the apparel industry in order to not loss money and accumulate stock.
The well known Inditex brand, Zara, is a good example of it. Moreover, its supply chain is its competitive advantage.

The supply chain of Zara is an icon, relying on a contrarian strategy of vertical integration in retail apparel to introduce dramatically more new items each year. The virtuous circle this approach sustains includes more frequent shopper visits to stores, fewer sales on markdown and faster cash conversion cycles.

The relatively recent trend of offshore sourcing in the apparel industry has led to long production lead times due to which companies operating in the field need to buy products months in advance their sale. This has increased the importance of demand forecasting in the apparel industry but Zara works in a completely different way.

Zara works with just in time production. It keeps a significant amount of its production in-house and makes sure that its own factories reserve 85 percent of their capacity for in-season adjustment. Instead of offshoring working in-house allows the organization to be flexible in the amount, frequency, and variety of new products to be launched.

It is true that the wages of the European workers are higher than the offshoring workers, but the turnaround time is miraculous.

Zara also commits six months in advance to only 15 to 25 percent of a season’s line. And it only locks in 50 to 60 percent of its line by the start of the season, meaning that up to 50 percent of its clothes are designed and manufactured smack in the middle of the season.
On the demand-sensing side, Zara was a pioneer in using technology, including PDAs (personal digital assistants) to capture real-time consumer data not only on transactions, but also on preferences underlying perceptions of value. Once they know what the customers prefer, store managers report customer feedback to Zara’s designers who begin sketching
This then translates to frequent shipments and higher numbers of customer visits to the stores, creating an environment of shortage and opportunity.

This strategy allows Zara to sell more items because of the sense of scarcity and exclusiveness. Is because of that Zara’s total cost is minimized because the reduction in stock as compared to competitors. As they save money, Zara can afford extra labor and shipping costs needed to satisfy changes in customer demand.

Inventory optimization models are put in place to help the company to determine the quantity that should be delivered to every single one of its retail stores via shipments that go out twice every week.

Many experts believe that the secret of Zara to their success has been the centralization that allows making decisions in a very coordinated manner. Each store sends in two orders per week on specific days and timing. Garments are already labeled and priced upon destination. Every staff involved knows the timeline and how their activities pan out with respect to other functions what is also extended to the customers who know when to visit stores to find new clothes.

Zara’s strong distribution network enables the company to deliver goods to its European stores within 24 hours, and to its American and Asian outlets in less than 40 hours.

Nowadays, Zara is trying to see if a new way of distribution for the e-Commerce works. Until now, they have used the “click and collect” based on buying through the web and pick it up in the store. But now Zara wants to send a QR code or PIN number with the data of your purchase and that this serves as 'key' to pick it up in a box office locate in the store. Always developing new ideas in order to reduce cost and optimize the logistics.

To sum up, we could say that Zara don’t work with demand forecast as their major part of the clothes are designed and manufactured in the middle of the season relaying on what the customers like more. This can be achieved because of the just in time production.
