The definitions of the 9 elements of a work system are as follows:
Processes and activities include everything that happens within the work system. The term processes and activities is used instead of the term business process because many work systems do not contain highly structured business processes involving a prescribed sequence of steps, each of which is triggered in a pre-defined manner. Such processes are sometimes described as “artful processes” whose sequence and content “depend on the skills, experience, and judgment of the primary actors.” (Hill et al, 2006) In effect, business process is but one of a number of different perspectives for analyzing the activities within a work system. Other perspectives with their own valuable concepts and terminology include decision-making, communication, coordination, control, and information processing.
Participants are people who perform the work. Some may use computers and IT extensively, whereas others may use little or no technology. When analyzing a work system the more encompassing role of work system participant is more important than the more limited role of technology user (whether or not particular participants happen to be technology users)
Information includes codified and non-codified information used and created as participants perform their work. Information may or may not be computerized. Data not related to the work system is not directly relevant, making the distinction between data and information secondary when describing or analyzing a work system. Knowledge can be viewed as a special case of information.
Technologies include tools (such as cell phones, projectors, spreadsheet software, and automobiles) and techniques (such as management by objectives, optimization, and remote tracking) that work system participants use while doing their work.
Products and services are the combination of physical things, information, and services that the work system produces. This may include physical products, information products, services, intangibles such as enjoyment and peace of mind, and social products such as arrangements, agreements, and organizations.
Customers are people who receive direct benefit from products and services the work system produces. They include external customers who receive the organization's products and/or services and internal customers who are employees or contractors working inside the organization.
Environment includes the organizational, cultural, competitive, technical, and regulatory environment within which the work system operates. These factors affect system performance even though the system does not rely on them directly in order to operate. The organization’s general norms of behavior are part of its culture, whereas more specific behavioral norms and expectations about specific activities within the work system are considered part of its processes and activities.
Infrastructure includes human, informational, and technical resources that the work system relies on even though these resources exist and are managed outside of it and are shared with other work systems. For example, technical infrastructure includes computer networks, programming languages, and other technologies shared by other work systems and often hidden or invisible to work system participants.
Strategies include the strategies of the work system and of the department(s) and enterprise(s) within which the work system exists. Strategies at the department and enterprise level may help in explaining why the work system operates as it does and whether it is operating properly.
