The organizations and people dimension  sets out the people aspects of service management to be considered when designing, operating and changing service offerings . People include employees, managers, executives, customers, supplier employees, or anybody else who is involved in the creation or consumption of services.

A help desk is considered to be focused on break-fix (what ITIL calls incident management), whereas a service desk is there to assist with not only break-fix but also with service requests (requests for new services) and requests for information (such as “how do I do X?”).

No service, practice, process, department, or supplier stands alone. The outputs that the organization delivers to itself, its customers, and other stakeholders will suffer unless it works in an integrated way to handle its activities as a whole, rather than as separate parts.

Taking a holistic approach to service management includes establishing an understanding of how all the parts of an organization work together in an integrated way (remember the four dimensions of service management?), including having an end-to-end visibility of how demand is captured and translated into outcomes. In a complex system, the alteration of one element can impact others and, where possible, these impacts need to be identified, analysed and planned for.

To apply this principle successfully, consider this advice:

Recognize the complexity of the systems

Collaboration is key to thinking and working holistically

Where possible, look for patterns in the needs of and interactions between system elements

Automation can facilitate working holistically

Costs are the amount of money spent on a specific activity or resource. From the service consumer’s perspective, there are two types of cost involved in service relationships:

Costs removed from the consumer by the service (a part of the value proposition).  For example, for a car sharing service, the customer does not pay for the actual cost of purchasing the car.
