To make the most of your salary benchmarking efforts, you should use multiple and credible data sources. Don't rely on a single source or method to get your salary data, instead use a combination of surveys, reports, online tools, and your own research. Additionally, it is important to match your roles and skills with those of the market as closely as possible. Consider the level of responsibility, complexity, and impact of each role, as well as the skills, qualifications, and experience required. Furthermore, it is essential to update your data regularly. Don't use outdated or stale data - update your data at least once a year or more frequently if needed in order to keep up with the trends and fluctuations. Finally, involve your employees and managers in the process by soliciting their feedback and input. This can help you gain their buy-in and support, as well as improve your data quality and accuracy.
