What influences whether a service is perceived as valuable by a consumer?

A service is perceived as valuable when its positive effects outweigh its negative effects for the consumer. That is why option C is correct. In ITIL, value is not defined only by what the provider delivers. It depends on the consumer’s perception of benefits, usefulness, and importance. Consumers evaluate whether the service helps them achieve desired outcomes while optimizing associated costs and risks. Even a technically strong service may be seen as low value if it is hard to use, unreliable, expensive, or creates unwanted effort. Conversely, a service with well-balanced utility, warranty, sustainability, and experience may be seen as highly valuable. Provider investment or internal efficiency alone does not determine value. ITIL places emphasis on outcomes and stakeholder perception, which is why consumer judgment about net positive effect is central.
