People-Focused Solutions to Demand Planning

Minor Communication Errors Lead to Excess Inventory

Even a well-defined sales and operations planning (S&OP) process contains knowledge gaps that reduce demand plan accuracy. Over time, these small errors lead to a costly buildup of inventory. 

Lack of sharing between sales, demand planning, and supply chain

Inconsistent communication between Sales, Business Leaders, and Supply Chain Management

sales forecasts from large customers aid in demand planning

Failure to collect sales forecasts from large, repeat customers


Demand forecasts do not incorporate historical sales trend

These planning errors result in building the wrong inventory, leading to accumulation of unsold product. I help you build a robust and repeatable planning process, ensuring you only build the right inventory.

Solving Communication Gaps

People-Focused Approach to Demand Planning

Step 1: Process Review

At its core, demand planning is simply a tool to communicate future demand to the manufacturing plant. While it’s easy to focus solely on the technical aspects of this process, I take the time to learn how this communication works in your business today:

  • Do you employ dedicated planners at your business?
  • Do you review the demand plan with your supply chain management?
  • How do you you incorporate historical data?
  • Have you identified demand patterns in recent sales data?

Step 2: Quantitative Analysis

calculate forecast error and bias by comparing actual sales data at your company with your prior forecasts of future demand. I compare your inventory levels against benchmarks from comparable supply chains in your industry.

Step 3: Eliminate Communication Gaps

After learning the existing process, I lead you through several steps to increase the accuracy of your demand forecasts. We begin by building a transparent process that ensures clean, simple communication between your sales team, your demand planners, and supply planners. I help you define consistent rules, such as when to include the impact of new customer wins.

We structure a regular meeting cadence in which we share the demand forecast with your key leaders from sales, marketing, and manufacturing. These meetings are designed to solicit insights and feedback from these critical functions, increasing the accuracy of the forecast.

Step 4: Identify Demand Patterns

With a repeatable communication structure in place, we can then focus on the statistical component of demand planning. I identify demand patterns from historical sales data, and use this analysis to increase forecast accuracy. Together, we identify industry or economic indicators that may help us better predict future demand.

Finally, I examine the product portfolio and identify product variants that contribute excessive volatility to historical demand. Many product variants actually generate losses for the company, as their unpredictable demand results in excess inventory levels over time.

Example of My Work

Problem: Excess Inventory, Unfilled Orders

Inventory is spiraling out of control at a large industrial business, but customers are still waiting months for unfilled orders.

My Approach: Audit the Entire Process

I learned how the sales team built the sales pipeline, and at what steps in the sales cycle they declared wins.

I met with the demand planners to see how they created the demand forecast. How did they include the sales pipeline? What tools did they use to spot trends?

The plant controller provided the production (supply) plan, as well as details of existing inventory that was near expiration.

My Findings: Multiple Issues Creating Excess Inventory

I identified a number of items that each added forecast error.

Collectively, these errors created a production plan that was only 25% accurate. This created massive inventory levels for some products, while other products were constantly out of stock.

Collaborative Approach

How I Add Value

Assist in simplifying demand planning process

Design Transparent
Plan Process

The demand plan is often built in silos, with little coordination between the sales leaders and manufacturing teams. 

Because there is no shared ownership of the demand plan, there is little incentive to improve the plan process in future periods.

How I Help:

I partner with you to build an effective plan cycle, referred to as the sales and operations planning (S&OP) process.

Together, we develop a communication framework that enables simple, repeatable flow of information between the sales leaders and supply chain management.

Build collaboration with demand planner

Build Collaboration
with Business Partners

Demand planning is frequently considered a supply chain activity, and key business leaders are excluded from this critical process.

As example, the marketing function is best equipped to speak to broad industry trends, and their input can materially increase the accuracy of any long term forecast.

How I Help:

I help you design a meeting cadence in which marketing and other business leaders can share their insights at various steps in the plan cycle.

Savings from sales and operations planning process

Savings Potential

The benefits of improved demand forecasting are felt across the business, resulting in lower inventory waste, reduced storage cost, and higher fill rate. 

Because it is hard to measure, many businesses don’t realize the true cost of a poorly-executed demand planning process.

How I Help:

By performing a thorough review of historical data, I measure the savings achievable with only modest increases in forecast accuracy:

  • Lower inventory waste
  • Reduced warehouse usage
  • Higher order fulfillment
  • Higher plant utilization

Demand Planning as Unique as Yourself

Demand planning team is using a whiteboard

Your business thrives because of its unique identity.
I provide demand planning consulting to a variety of businesses, each of which is special in its own way. Planning is so much more than a statistical calculation on a spreadsheet. It embodies key elements of your business, such as customer behavior and sales team motivation.

"An effective demand planning process is built around your special culture, and adapts to your way of doing things. Not the other way around."

I seek to understand the underlying behavior that drives product demand, and help you build a forecasting process tailored to your unique culture. In doing so, I will dramatically improve the accuracy of your demand plan, resulting in lower inventory and higher customer fill rate.

I Will Always:
  • RECOGNIZE your uniqueness
  • LEARN your sales cycle
  • IDENTIFY customer order patterns
  • DISCOVER cause of forecast misses
  • DESIGN a plan process that works for you
  • VALIDATE forecast results
I Will Never:
  • FORCE a generic solution
  • MANDATE changes to your systems
  • ASSUME a statistical tool can completely explain your business

Reduced Waste and Higher Sales

Why is Demand Planning Important?

Reduce Inventory

I once had a manager who frequently reminded us that inventory was evil. It cost to build, store, transport, and dispose. He recognized inventory management is a huge drag on company resources. 

In fact, it costs $20 per year to maintain $100 of inventory, as storage and handling costs are super expensive. It is estimated it costs $2 each time an employee touches inventory, and it costs even more when that inventory is transported between locations. 

"Inventory is Evil; it costs you to make it, it costs you to ship, it costs to store it, and it costs when you dispose of it"

Eliminate Expired and Obsolete Inventory

An average of 4% of all production is scrapped due to expired and obsolete inventory. For a business with $100 million in sales and 50% gross margin, inventory waste would represent an annual expense of $2 million. Effective demand planning can nearly eliminate expired and obsolete inventory, resulting in a dramatic improvement in inventory waste.

Higher Sales

Across industries, the average fill rate is 95%. Said differently, 5% of all orders are delayed due to insufficient on-hand inventory. Many of these orders will get cancelled, as customers will elect to use alternate vendors. 

A robust demand planning approach will yield higher fill rate, resulting in fewer cancelled orders. By increasing fill rate even marginally, a business could potentially increase sales by 3-5%.
