What is Demand Planning?
Demand planning is the process of predicting the future demand for a product or service based on various factors such as historical sales, market trends, and customer behavior.
- It is an essential aspect of inventory management that helps businesses make informed decisions about how much product to manufacture or purchase when to do it, and how to distribute it.
- Demand planning aims to align the supply of goods with customer demand to ensure enough inventory to meet customer needs while reducing excess stock.
- Accurate demand planning is critical for businesses because it helps reduce the risk of stock shortages and overproduction.
- By predicting demand, companies can ensure that they have the right amount of inventory on hand to meet customer needs, which can improve customer satisfaction and increase sales.
On the other hand, overproduction can result in excess inventory and wasted resources, leading to increased costs and reduced profits.
Optimize With Inventory on Demand
Inventory on demand is a management method that helps businesses optimize their inventory levels by keeping only the amount of stock needed to meet current customer demand.
This approach allows companies to reduce the cost of excess inventory and improve overall inventory management.
- Supports Just-In-Time (JIT) Inventory Management: Inventory on demand supports Just-In-Time (JIT) inventory management, which is an approach to inventory management that involves keeping only the minimum amount of inventory needed to meet customer demand. JIT helps reduce inventory carrying costs and improves supply chain efficiency.
- Supports Sales and Marketing Efforts: Inventory on demand provides businesses with the information they need to make informed decisions about production, purchasing, and distribution, supporting sales and marketing efforts.
- Increases Visibility and Control: Inventory on demand helps businesses gain visibility into their inventory levels and improve control over their inventory management processes, reducing the risk of stock shortages and improving overall supply chain efficiency.
- Enhances Responsiveness: Inventory on demand helps businesses respond more quickly to changes in customer demand, ensuring that they have the right products in stock when customers want them.
- Supports Inventory Optimization: Inventory on demand supports inventory optimization, which involves balancing inventory costs and stock shortage costs to find the optimal inventory level. Inventory optimization helps businesses improve their overall inventory management and increase profits.
Steps for Developing a Demand Planning Strategy
Gather Data
The first step in developing a demand planning strategy is to gather data. This data can include historical sales data, market research, and information about the competitive landscape. This data will provide a foundation for making informed decisions about production, purchasing, and distribution.
Analyze Data
The next step is to analyze the data that has been gathered. This analysis should focus on identifying trends, patterns, and other information that can inform the demand planning process.
For example, research may reveal that sales of a particular product are highest during a specific time of year or that a new competitor has entered the market.
Develop a Demand Forecast
The next step is to develop a demand forecast based on the gathered and analyzed data. This forecast should be based on the best available information and consider factors such as seasonality, trends, and market conditions.
Determine Inventory Levels
The next step is determining the appropriate inventory levels for each product based on the demand forecast. This will involve balancing the costs of inventory and the costs of stock shortages to find the optimal inventory level.
Implement Inventory Management Processes
Once the appropriate inventory levels have been determined, the next step is implementing inventory management processes. This may involve using software or other tools to track inventory levels, setting up processes for ordering new inventory, and establishing procedures for monitoring and adjusting inventory levels as needed.
Evaluate the Demand Planning Strategy
The final step is to evaluate the demand planning strategy on an ongoing basis. This evaluation should focus on determining the accuracy of the demand forecast, the effectiveness of the inventory management processes, and the overall impact on customer satisfaction, profits, and supply chain efficiency.
Continuously Improve
It is essential to improve the demand planning strategy over time continuously. This can involve making changes based on the evaluation results, incorporating new data and information, and adjusting the approach as needed.
Demand Planning Methods
Moving Average Method
The moving average method is a simple method that uses a moving average of past demand to predict future demand. This method can be used to smooth out fluctuations in demand, making it a helpful approach for products with moderate variability in demand.
Weighted Moving Average Method
The weighted moving average method is similar to the moving average method but assigns greater weight to more recent data. This method can be used to reflect changes in demand that have occurred more recently, making it a helpful approach for products with rapidly changing demand.
Exponential Smoothing Method
The exponential smoothing method is a more sophisticated method that uses an exponential formula to smooth out fluctuations in demand. This method can be used to adjust the forecast based on past demand and can be helpful for products with moderate to high variability in demand.
Trend Projection Method
The trend projection method is a method that uses historical data to identify trends in demand and then projects these trends into the future. This method can predict demand for products experiencing significant growth or decline and can be helpful for products with high variability in demand.
Regression Analysis Method
The regression analysis method is a statistical method that uses historical data to identify relationships between demand and other factors, such as price or advertising. This method can be used to identify trends and patterns in demand and can be helpful for products with moderate to high variability in demand.
Causal Modeling Method
The causal modeling method is a method that uses historical data and information about other factors, such as promotions or events, to predict demand. This method can be used to identify the impact of these factors on demand and can be helpful for products with moderate to high variability in demand.
Judgmental Method
The judgmental method is a method that relies on the expertise and judgment of the demand planner. This method can be used to incorporate subjective factors, such as market intelligence or personal experience, into the demand planning process.
What does a Demand Planner Do?
A demand planner is a professional responsible for forecasting and planning the demand for products and services. The demand planner is critical in ensuring that a company's inventory levels are aligned with customer demand, helping minimize costs, optimize sales, and improve customer satisfaction.
