In the fast-changing business environment of today, aligning demand forecasting, supply planning and production scheduling is not just a best practice, it’s essential. In our recent webinar, Ludovic Lezenven, Principal Business Consultant at QAD, discussed the connection between strategic planning and day-to-day execution. He stressed how important this link is for achieving a good balance.

In this blog article, the word “planning” is referring to end-to-end supply chain planning. This includes Sales and Operations Planning, Demand Planning, Production Planning, and Advanced Scheduling.
The webinar delved into three critical dimensions of effective planning:

1. Organizational structure and processes
2. Planning horizons and timelines
3. Tools needed to support decision-making.

Let’s explore the key insights that emerged from this discussion.

Building an Effective Supply Chain Planning Organization: Structure Drives Success

Supply Chain Planning and Scheduling isn’t just about having the right tools. At its core, it’s about people. The organization that structures, pilots, and improves planning processes all the time, is the true engine behind a successful supply-demand balance. 

This helps you make the right choices to meet customer needs. It also allows you to use your production capacity well without hurting your inventory levels.

“Organization is the key,” Ludovic Lezenven emphasized. “It’s the people, the actors within the company who will structure, pilot, optimize, and improve these planning processes all the time.“

This human element requires several foundational components:

Truth-based exchanges

Planning meetings must be grounded in verified information, not speculation. Participants in this meeting, like the planning manager, need to cite sources when suggesting ideas or options. This ensures that discussions are based on facts, not assumptions.

Equal weight to all voices

Effective planning organizations avoid social phenomena where one department (often finance or sales) dominates conversations. Every team member, whether from sales, marketing, finance, or operations, should have an equal voice in the planning process.

Again, at the end of the day, the goal is to make the best resource allocation from forecast demand to production line. 

Establishing trust

The planning process relies on trust between departments, built through empathy and reliable communication. This trust isn’t automatic, it’s developed over time. When trust grows, teams better understand each other’s challenges and priorities. That understanding leads to stronger decisions.

To make this work, companies need clear and consistent communication channels. These ensure the right information flows to the right people, at the right time.

Creating rituals

One concept that Ludovic Lezenven particularly emphasized was the importance of establishing regular planning rituals:

“Rituals are important because they allow humans to advance things, make progress, and create empathy. These elements can be reproduced for continuous improvement in a structured way.“

These rituals are key to good planning. They help team members communicate well and build agreement across departments.

The Crucial Time Dimension: Different Industries, Different Horizons of Planning and Scheduling

One of the most surprising parts of the webinar was the talk about demand and supply chain planning. The scheduling horizons can change a lot between different industries.

The temporal requirements for planning depend heavily on your business sector:

Fresh food and very short life cycle products

These typically operate on extremely short-term planning cycles, from daily forecasts to three-month projections. Long-term planning might extend to just one year, given the perishable nature of the products. AI in Advanced Planning & Scheduling (APS) for Food & Beverage manufacturers is a solution to explore.

Consumer goods and retail

These sectors commonly work with weekly or monthly short-term plans, while extending medium-term projections to 52 weeks. Long-term planning typically reaches one to two years ahead.

Seed producers and agricultural suppliers

These businesses often have production cycles that last a full year. They need to plan three years ahead to match supply with expected demand.

Automotive and aerospace

Perhaps most striking was the discussion of these sectors, where planning horizons can extend to 5-10 years. As Ludovic Lezenven explained, “I’ve worked on aerospace situations with 10-year projections since equipment parks might operate for decades.“

Impact on data management 

Different time frames greatly affect how companies plan their demand and supply chains. They also influence how data is managed over time. The further into the future you plan, the more you must contend with decreased data quality and availability.

“Unfortunately, despite all efforts, data tends to lose quality and availability over longer horizons,” Ludovic Lezenven noted. “This reality requires organizations to adapt their planning approaches accordingly.”

To tackle this, many organizations adopt a more aggregated approach for long-term planning. This involves focusing on product families over individual SKUs, and broader market segments instead of specific customers. 

The Technology Foundation: Tools That Orchestrate Supply Chain Planning and Scheduling 

While people and processes form the foundation of effective planning, technology plays a crucial supporting role. Ludovic Lezenven used a compelling metaphor to describe the relationship between planning processes and supporting tools:

“The organization establishes and pilots these processes. The tools are only there to support these processes through the organization that executes them,” added Lezenven.

He likened comprehensive planning systems to an orchestra, where:

1. The orchestra itself represents the core planning engine. Those are the tools that balance demand and supply planning, optimize resources, and enable scenario planning.
2. The musicians are the planners and schedulers. They focus on specific tasks like demand forecasting, inventory management, and production scheduling.
3. The opera house is the analytics layer that showcases the results in a compelling, decision-ready format, highlighting anomalies. Analytics enable detailed analysis for efficient and faster decision-making.

Effective advanced planning and scheduling tools should provide:

Scenario capabilities

The ability to model different demand and capacity scenarios and evaluate their financial impacts.

Data-driven depth

Tools help planners start with overall views. They can then dig deeper to find specific issues with products, customers, or time periods.

Financial visibility

Clear view of projected costs, revenues, and margins to support informed decision-making.

“These tools must allow you to identify strong or weak product turnover rates and review the strategic positioning of inventory in real time,” Ludovic Lezenven explained. This capability becomes particularly important when deciding whether to position inventory closer to markets (for high-turnover products) or keep it upstream at production facilities (for slower-moving or highly customized items).

Creating Cohesive Supply Chain Planning and Scheduling Processes

What makes planning truly effective is how these elements—organization, time horizons, and tools—work together. Each planning role focuses on different time horizons, but with crucial overlapping zones:

Forecasters: Might work primarily with monthly and weekly projections

Supply planners: Need to project further into the medium term to account for lead times

Production planners: Typically focus on weekly or daily views

Schedulers: Operate at the finest granularity—hours or even minutes

These overlapping zones create natural handoff points between planning functions, but they can also become areas of conflict. Clear ownership and responsibility definitions are essential to prevent gaps or disputes.

“These overlap zones, which are generally conflict zones—’it’s not my responsibility, it’s the other person’s responsibility’—need to be clearly defined and decided upon in a shared, common way,” Lezenven advised.

Moving Forward: Creating Your Advanced Planning & Scheduling Roadmap

As we reflect on the webinar insights, several critical questions emerge for organizations looking to enhance their planning capabilities:

1. Are your planning rituals clearly established and consistently followed?
2. Do all stakeholders—from operations to finance to sales—have an equal voice in planning discussions?
3. Have you aligned your planning horizons with the specific needs of your industry?
4. Are your tools supporting both the detailed calculations and the high-level analytics needed for effective decision-making?

The answers to these questions can help chart a course toward more effective planning processes that truly balance demand and supply across your organization.

By creating structures that foster trust, establishing appropriate time horizons, and leveraging the right supporting tools, you can develop planning processes that not only respond to market demands but anticipate them—creating a genuine competitive advantage in an increasingly dynamic business environment.
