What is Demand Planning and Why It is Important?

You may have come across the term demand planning with regard to inventory management and/or supply chain.

That is because it’s a process that is valid across functions, and helps fulfil customer demand for goods without disrupting the supply chain, and with little excess inventory.

This can help you increase revenues and keep your customers satisfied while improving overall efficiency.

The demand planning process needs to be a continuous one – something that is an essential part of your business.

Thanks to technological advancements and the emergence of software like Tranquil, this is not just possible, but even easy.

It is necessary to analyze customer trends, historical sales data, and seasonal trends so that you can ensure that your business is capable of meeting customer demand very effectively.

For this, demand planning merges supply chain management, inventory management, and sales forecasting.

It makes use of data from inside and outside sources to forecast future demand.

This prediction can help you form your strategy for sales and operations, enabling you to plan how much to produce or purchase to be able to fulfil the demand.

What are the Elements of Demand Planning?

While there are several aspects to demand management strategy, the following three are the most important:

Product Portfolio Management

This refers to the management of the entire product lifecycle – from product launch to its life-ending.

Product lines are often interdependent; it is important to understand the way new products can influence the demand for other items, to get a clear picture of the product range you need to enjoy the lion’s share of the market.

Statistical Forecast

Statistical forecasts leverage historical data to generate supply chain forecasts with sophisticated algorithms.

Here it is critical to ensure model accuracy, understand conjectures, and pinpoint deviations and exclusions.

Seasonal trends can also be evaluated via statistical forecasts.

Effective demand and supply planning drives profitability and boosts customer satisfaction as it helps businesses to attain the proper balance between fulfilling customer demand and adequate inventory.

This necessitates cross-organizational collaboration and is not an easy task.

As extra inventory ties up finances, and you run the risk of being stranded with dead or very low-value stock, it can have a significant impact on your business.

Or you may face severe disruptions in your supply chain, leading to a shortage of products, which could cause backorders or emergency purchases, which are always expensive.

Basically, with improper planning, you are likely to face delays and unhappy customers.

Demand Planning vs. Demand Forecasting

For predicting sales, businesses study both internal and external data; for this, first, a demand forecast has to be made.

These are all part of the inventory demand planning process.

Normally, demand is forecast for the near future – up to a maximum of 24 years; however, this depends on the industry as well as the product.

Businesses may need to make adjustments in the forecasts to reflect market conditions and customer trends.

The demand forecast forms the basis for the entire process of demand planning.

Where Does Demand and Inventory Planning Sit Within a Business?

The process of demand planning necessitates inputs from multiple departments like purchase, production, operations, finance, marketing, supply chain, and sales.

They also need to collaborate well with each other.

Business strategy planners and product portfolio managers have to consider lead times for production and raw materials.

Demand and inventory planning involves several business functions, and so the employees handling the related tasks may be spread across departments, or be a separate group altogether.

However, to achieve the best results, demand forecasting is most accurate and successful when linked closely to marketing and sales.

7 Key Steps for Successful Demand Planning

7 Key Steps for Successful Demand Planning

Demand planning is multifaceted and complex, and becomes more so with business growth.

  • It’s important to create a cross-departmental team with clearly assigned roles and responsibilities. Like purchase department is tasked with ensuring sufficient and timely inventory, and so on.
  • The employees involved in demand planning have to reach a consensus on what data to include for creating a precise prediction. This will differ for each business, but some common elements are sales data per location and platform, inventory turnover, production times, lead times, out-of-stock rates, dead stock, and other KPIs. Marketing and sales teams can be consulted for price change timings, marketing campaigns, and more that could impact demand. Product teams should inform regarding new products, competitors’ products, and other factors that could affect the precision of the forecast.
  • External data is critical and should be used for robust forecasts. Examples are suppliers’ delivery timelines, performance, consumer buying habits, and market conditions that could impact your sales.

  • Create a statistical demand prediction after deciding which forecasting prototype is apt for your business. Demand planning software can help you do this accurately and quickly. You can also generate forecasts by regions, customers, and products in addition to organizational predictions.
  • Evaluate and hone the demand predictions with the important stakeholders. Add the latest data to check if it affects the forecast significantly. Examine any info you feel is erroneous, and eliminate deviations that could alter the overall forecast. Make sure that the prediction is in tune with the wider financial predictions of your company.
  • Compare the predictions with your inventory, check how much you need to fulfil the forecasted demand, and add a buffer to it. Find the suppliers who can meet this demand and ensure they are capable of delivering what you need when you need it. Also, ensure the transportation is able to handle the volume of product in the time you want.
  • Lastly, measure the results so that you know how successful your strategy has been. It is important to review your performance regularly and make the requisite changes.

Demand Planning Tools and Methods

There are two broad approaches to demand planning – push and pull.

The push method assumes that people will come if you build something great – a philosophy that was used till very recently.

Businesses believed that to create demand it was enough to be innovative with products. So, they would manufacture products and wait for sales to happen.

But this strategy did not succeed always. Unexpected demands led to stockouts and missed opportunities for sales, or excess inventory piled up on shelves and warehouses, leading to expenses.

It was extremely difficult to strike a balance.

The modern method is the pull approach – here the business assesses consumer demand, and bases overall planning on that.

The main difficulty here is getting a correct forecast of consumer demand; with incorrect predictions, you may have the same negative effects of the push method.

Today, to help overcome these problems, we have modern demand planning tools:

  • Linear regression – puts prior demand levels into statistical models for sales forecasting. Also called the line of best fit, the model uses prior demand to plot a curve, and expands it to make demand forecasts.
  • Moving average demand – believes that demand in the future will be an average of the past few sales periods.
  • Sales forecast – generates an approximate future demand on the basis of sales opportunities and prospects discovered by the business for a specific period.
  • Seasonal trends – makes demand forecast by evaluating historical sales in specific seasons, and is suitable for businesses with highly seasonal sales.
  • Companies combine these methods with demand planning software so that predictions and modeling can be automated, and be more reliable and precise.
