Which of the following questions does the guidance in service strategy help to answer? (1) What services should we offer and to whom? (2) How do we differentiate ourselves from competing alternatives?

Selecting only question 1 ignores that Service Strategy also directly addresses competitive differentiation and the creation of customer value.

Selecting only question 2 ignores that Service Strategy also covers service portfolio decisions and the mechanisms for value creation.

Selecting only question 3 ignores that Service Strategy also guides decisions about which services to offer and how to differentiate from alternatives.

ITIL Service Strategy is the lifecycle stage that provides guidance on the foundational strategic decisions of an IT service provider. It explicitly covers defining the service portfolio and target markets (question 1), positioning the provider against competing alternatives (question 2), and establishing the mechanisms through which services deliver value to customers (question 3). All three questions are core concerns of Service Strategy, making 'All of the above' the only complete and correct answer.
