What is trend analysis?

Trends viewed as particularly important in a specific community, industry, or sector are carefully monitored, watched, and reported to key decision makers
When numerical data are available, a trend can be plotted to display changes through time and into the future
Complex systems can be modeled by means of mathematical equations and different scenarios can be run against the model to determine "what if" analysis
A trend is examined to identify its nature, causes, speed of development, and potential impacts
