Definition
Forecasting is the process of estimating future events, values or trends using historical data, analytical models and defined assumptions.
Human Explanation
Forecasting helps estimate what may happen in the future.
Why it Matters
It supports earlier planning, resource preparation and risk reduction.
Conceptual Boundary
Forecasting does not predict the future with certainty. Results depend on data quality, model choice, assumptions and whether the conditions represented by past data remain relevant.
Practical Perspective
Forecasts are used in sales, production, inventory and budget planning. Their uncertainty and accuracy should be monitored instead of presenting a single estimate as a guaranteed outcome.
Common Analytical Sequence
Time Series organises observations over time. Trend Analysis examines their direction and pattern. Forecasting uses available evidence to estimate future outcomes.
This is a common sequence, not a mandatory dependency. Forecasts may also use causal variables, cross-sectional data, simulations or expert judgement.
