The next step is to analyze the situation and identify what went wrong and why. Try to be objective and factual, and avoid blaming yourself or others. Consider the factors that were within and outside your control, such as your preparation, presentation, negotiation, communication, cultural awareness, customer feedback, market conditions, competitors, etc. Ask yourself what you did well and what you could have done better. Seek constructive feedback from your manager, team, or client, and listen with an open mind.
