Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Trend analysis means analysis of tendencies. Usually you collect data at different points in time and analyse curves.
Examples:
1) analysis of success probability trends - you calculate probabilities of meeting project targets during project execution and create curves. Negative (when success probability goes down) tendencies (trends) show that corrective action is necessary,
2) analysis of CPI (Cost Performance Index) and SPI (Schedule Performance Index) trends. If they go down then project performance became worse.
We always recommend to analyse trends. It helps to notice negative tendencies early and to apply necessary corrective actions until it became too late.
