Forecasting and Trend Analysis

Forecasting and Trend Analysis


Forecasting techniques are a key part of decision making, affecting planning at all levels: strategic, tactical and operational. Effective and accurate forecasting techniques are particularly important in a dynamic, changing and uncertain environment. They are indispensable for coordination, execution, and risk management. An understanding of the fundamentals of forecast assessment is vital for all managers and executives. Knowing how to calculate and build different kinds of forecasts is a related, specialised skill.

Examining "what has happened" is a necessary precursor to predicting "what will happen" in the future. Time series analysis is thus an important forecasting foundation.

This one-day course provides a grounding in both time series analysis and forecasting.


2 Days


Attendees will, by the end of the course have been exposed to:

  • The fundamentals of time series composition and analysis.
  • Methods  to assess any forecast, and accordingly how to measure the performance of any forecasting team, model, method, or process.
  • The strengths, weaknesses, and applications of a range of statistical and judgement-based forecasting techniques.


This course is suitable for all managers, executives and specialists who want to make better decisions under uncertainty. It requires no specialised statistical knowledge, nor knowledge of R.
