Compliance aside, an effective HR audit is often considered a best practice in modern human resources management. However, best practices vary between industries and even among organizations. What works well for one organization may not work for another. Best practices need to be tailored by taking factors such as industry, company size, demographics, finances and competitive information into consideration.

The results of an HR audit can be used as a benchmarking tool, helping organizations achieve best practices. Benchmarking the organization also helps to promote specific HR programs to senior management. In addition, where relevant programs are already in place, improved audit results from year-to-year can confirm program success.
