Study Notes

Forecasting Definitions and Experts

Forecasting is the art and science of predicting future events using historical data and trends.
Forecasting involves estimating future occurrences like demand, costs, or quality issues.
Forecasting experts define it as predicting future events, often projecting historical data into the future, using a mathematical model.
Forecasts are estimates of an event's timing, occurrence, or magnitude.
A forecast is a prediction of what will happen in the future.

Forecasting Applications in Operations Management

Forecasting helps manage operations by planning and efficiently distributing resources.
Demand forecasting predicts future customer demand for products or services, thus managing inventory, production, and resource allocation.
Capacity planning projects future production needs to ensure sufficient resources.
Supply chain forecasting manages procurement, logistics, and distribution. This maintains a smooth flow of materials.
Workforce planning projects future staffing needs.
Cost management forecasts future expenses for budgeting and expense control.

Forecasting's Role in Total Quality Management (TQM)

Forecasting supports quality improvement and customer satisfaction by aligning product or service quality with customer expectations.
Quality control uses historical data to predict potential quality issues and implement preventive measures.
Process improvement anticipates areas for efficiency and defect reduction.
Customer satisfaction involves forecasting customer needs to design and provide quality products and services.
Supplier quality management forecasts quality requirements to select and manage reliable suppliers.
Continuous improvement identifies trends for enhancing product and service quality.

Basic Laws of Forecasting

Forecasts are almost always wrong.
Short-term forecasts are more accurate than long-term forecasts.
Group forecasts are generally more accurate than single forecasts.
Forecasts are not substitutes for calculated values. They are used when a more precise method is not feasible.

Types of Forecasting: Qualitative vs. Quantitative

Qualitative forecasting relies on subjective judgment, suitable when historical data is not available. Helps in long-term predictions and new markets.
- Better in predicting consumer behavior.
- Flexible for interpretations to gather innovative ideas.
- Helps supplement incomplete data.
- Offers a better understanding of the underlying reasons behind trends.
Quantitative forecasting uses numerical data and mathematical models for predictions. Primarily useful for short-to-medium-range predictions where historical patterns exist.
- More accurate predictions than subjective ones, using numerical evidence.
- Minimizes personal bias by using objective historical data.
- Easily repeatable and reliable over time
- Strengthens relations with investors and customers.
- Helps identify patterns like purchasing trends and expenses.
- Streamlines data analysis using technology for broader forecasting.

Difficulties in Interpretation and Assumptions

Purely numerical data can be difficult to interpret without external context.
Quantitative forecasting relies on past trends continuing; however, this is not always the case.

Demand Forecasting Components

Average/Stationary Demand: Assumes no long-term growth.
Trend: Tracks overall movement (upward or downward) with trends like Linear, S-Curve, Asymptomatic, and Exponential trends.
Seasonal Variation: Predictable fluctuations based on seasons.
Cyclical Movements: Irregular changes due to factors like elections or economic shifts.
Random Movements: Unpredictable changes due to unforeseen events (e.g., natural disasters).

Quantitative Techniques in Forecasting

Time Series Forecasting: analyzes historical data to predict future outcomes (e.g., trend, seasonality)
- Naive Forecasting: assumes the next period will be the same as the last.
- Moving Average: smooths data by averaging past observations.
- Exponential Smoothing: gives more weight to recent data points.

Qualitative Forecasting Techniques

Delphi Technique: uses a panel of experts in independent rounds to provide forecasts until consensus is reached.
Market Survey: gathers direct input from potential customers using surveys or focus groups.
Judgmental Forecasting: relies on expert intuition, experience to predict future trends.
Scenario Writing: creates detailed scenarios based on future possibilities.

Qualitative Forecasting Approaches

Market Research: includes customer surveys, focus groups to gather consumer insight
Executive Judgment: company leaders leverage experience and expertise for strategic decisions with little or no historical data.
Historical Analogy: comparing a new product to a successful one with similar characteristics to predict market behavior and reception.

Quantitative Forecasting Approaches

Causal Forecasting: recognizes variables like population, income levels, and product prices to predict sales.
Time Series Forecasting: relies on analyzing historical data to predict future outcomes based on patterns.
