It is closely tied with Business Process Outsourcing, where certain HR tasks may be contracted to an external provider to streamline operations.

Business Process Reengineering, another related concept, involves rethinking and redesigning the way work is done to improve cost, quality, service, and speed, often playing a significant role in HR strategies. Business Analysis is another key aspect, with HR staff utilizing this to identify the organization's needs and determine solutions. Overall, Human Resources is a fundamental component of any Business, playing a pivotal role in managing the workforce, improving processes, and driving the organization's success.
