To prepare for performance reviews, one should identify key metrics by pulling verbs from their job description and mapping them to company goals. This process involves breaking down metrics into smaller parts and cross-checking them with departmental objectives. Once metrics are identified, set specific goals related to those metrics and create an assessment form using Google Forms to track progress. The form should include fields for project descriptions, metric names, related objectives, execution scores, positive feedback links, and screenshot uploads. To make the process more engaging, gamify the review by setting a win condition or reward system, and analyze the data regularly to identify areas for improvement. By contributing to performance reviews regularly, one can distill valuable data into a compelling story that showcases their accomplishments and prepares them for future opportunities.
