A more thorough explanation:

Definition: Ex post is a Latin term that means "from after." It refers to something that is based on knowledge and facts that are viewed after the fact, in hindsight. It is objective and retrospective, meaning it looks back at something that has already happened.

Examples:

• After the company went bankrupt, an ex post analysis showed that their spending habits were unsustainable.
• Ex post evaluations of government policies can help determine their effectiveness.
• Looking back at the stock market crash of 2008, ex post analysis revealed several warning signs that were missed at the time.

These examples illustrate how ex post analysis is used to evaluate something that has already happened. It allows us to look back and see what went wrong or what could have been done differently. By analyzing past events, we can learn from our mistakes and make better decisions in the future.
