Introduction

Forecasting demand is a critical component of strategic planning and operational efficiency within a business. Accurate forecasts enable organizations to optimize inventory, allocate resources effectively, and meet customer demand consistently. This paper explores the application of demand forecasting methods by analyzing three quantitative data points from a selected company. Through historical data collection, applying appropriate forecasting techniques, and evaluating forecast accuracy, this study demonstrates the practical utility of combining subjective and objective data for improved decision-making.

Selection of Quantitative Elements and Data Collection

The company chosen for this analysis operates in the retail sector, specifically focusing on seasonal product sales. The three quantitative elements selected include monthly sales volume, inventory levels, and customer orders. Historical demand forecasts, which were primarily subjective, were collected alongside actual demand outcomes for the past two years. The subjective forecasts were based on managerial intuition and experience, while the actual demand data was obtained from company sales records.

Establishment of Forecasting Methods and Data Analysis

Given the seasonal nature of product sales, a combination of moving averages and exponential smoothing was selected to project future demand. The balance between subjective and objective data was maintained by integrating managerial insights into the initial parameters of the models. Trend analysis revealed increasing demand during specific months, and seasonality was evident from periodic fluctuations in sales data. Visual charts generated from Excel displayed these patterns clearly, supporting model selection and refinement.

Forecasting Future Demand and Decision Making

Based on the configured models, future demand was forecasted for upcoming quarters. The forecasts indicated a continued seasonal increase in sales during peak months. These projections informed decisions on inventory replenishment and staffing. The models were validated by comparing forecasts against actual outcomes, with forecast errors calculated using Mean Absolute Percentage Error (MAPE). The results revealed an acceptable error margin, although minor biases were identified in certain months where sales were underestimated.

Biases, Error Measurement, and Process Improvement

Analyzing forecast errors uncovered a tendency to underestimate demand in the holiday season, likely due to unforeseen promotional activities. Recognizing this bias prompted an adjustment in the forecasting model to incorporate promotional calendars, thereby reducing errors in subsequent forecasts. Continuous monitoring and recalibration are vital for refining the accuracy of demand predictions.

Conclusion

This analysis underscores the importance of integrating both subjective managerial insights and objective data in demand forecasting. By applying suitable models and continuously evaluating their performance, businesses can enhance forecast accuracy, reduce costs, and improve customer satisfaction. The iterative process of model validation and adjustment is essential in maintaining reliable forecasts that adapt to changing market conditions.
