A large organization has a centralized service desk, and many different teams that help to resolve incidents and manage service requests. They also use many different suppliers to support these…

Question

Options

• AOne value stream for resolving incidents, and a separate value stream for managing service
• BOne value stream for the organization, and separate value streams for each supplier
• COne value stream for the organization, and separate value streams for each team
• DOne value stream for all activity that arrives via the service desk

• A
  6% (2)
• B
  3% (1)
• C
  3% (1)
• D
  89% (32)

Explanation

Option D is correct because the question asks for the minimum number of value streams, and a single value stream can theoretically handle all work arriving through the service desk - incidents, service requests, involvement of any team, and any supplier. ITIL 4 defines value streams as flexible constructs, not rigid structures tied to work type, team, or vendor. Nothing in the framework mandates splitting a value stream just because different teams or suppliers are involved.

Why the distractors are wrong:

• A assumes incidents and service requests must be separate, but both can flow through one stream - they are just different demand types, not mandatory separate streams.
• B assumes each supplier requires its own stream, but suppliers are participants within a value stream, not a reason to create new ones.
• C makes the same mistake as B - teams are participants within a value stream, not structural justifications for creating additional ones.

Memory tip: Lock onto the word "minimum" - ITIL 4 never forces you to multiply value streams. Ask yourself: could all this work theoretically flow through one series of steps? If yes, the minimum is one. You can always add more for practical reasons, but the exam wants the floor, not the ceiling.
