What type of system includes processes such as marketing, sales, and HR?

The correct answer is business systems. Business systems encompass the interconnected processes within an organization that facilitate the overall operations and strategy. Specifically, functions such as marketing, sales, and human resources (HR) are integral to driving the organization’s goals and objectives, making them core components of a business system.

Business systems are designed to align various departments and processes towards fulfilling customer needs and achieving business missions. Marketing drives demand and awareness, sales convert that demand into revenue, and HR manages the organizational talent necessary to execute these functions effectively. These elements together demonstrate how a business system operates holistically.

In contrast, operational systems generally refer to the tactical processes that directly deal with producing goods or delivering services. Support systems often pertain to auxiliary services such as IT support, while management systems are typically concerned with strategies and policies that guide and control business functions, rather than the functions themselves. Therefore, business systems provide the most comprehensive view of the interconnected nature of departments like marketing, sales, and HR.
