Due diligence

Due diligence is the careful review of information before making an important business decision, to understand risks and confirm key details.

What are diversity and inclusion?

Due diligence is the process of checking the facts before moving forward with a business decision, such as a merger, contract or major hire. It helps organisations spot risks early, confirm that information is accurate and make decisions with more confidence.

In HR, due diligence often focuses on people-related areas, such as contracts, pay practices, policies and workplace culture. It can also include reviewing compliance requirements and how a change might affect the employee experience.

Taking the time to do due diligence upfront can help avoid costly issues later and support a smoother transition for everyone involved.
