What is demand planning?
Demand planning refers to the set of processes used to anticipate future sales. It draws on historical data, market trends and sales assumptions. The goal: turn this information into reliable forecasts that feed the supply chain, production and finance.
Why demand planning has become strategic
Imagine managing 1,000 products, 3 markets and 4 distribution channels. How do you balance accuracy, responsiveness and peace of mind? Demand planning gives your supply chain, finance and sales teams the visibility they need to produce the right quantities, deliver on time and optimize margins.
Key steps in the process
1. Data collection. Sales history, seasonality effects, promotional impact.
2. Statistical forecasting. Exponential smoothing, ARIMA and machine learning algorithms applied to each SKU.
3. Collaborative enrichment. Sales reps adjust forecasts using their knowledge of the field.
4. Consensus and sign-off. A single demand plan, approved by all stakeholders.
5. Measurement and improvement. Forecast accuracy tracking, bias analysis, continuous improvement.
Mistakes to avoid
Relying solely on history without factoring in qualitative input. Ignoring granularity (forecasting in aggregate without breaking it down by product and market). Failing to measure forecast accuracy. Working in silos without involving the sales team.
Demand planning and supply chain: an inseparable pair
Demand planning feeds directly into S&OP, inventory management and production planning. Without reliable forecasts, the rest of the chain cannot be optimized.
The Ganacos approach
Lower logistics costs thanks to better inventory turnover. A more agile supply chain, able to anticipate and adjust in real time. Just 4 to 8 weeks to deploy an initial scope and turn planning into a strategic lever.
