b. _____ Requirements should be viewed hierarchically.
c. _____ Stakeholder Requirements are developed based on the engineer's interpretation of the solution.
d. _____ Good requirements should specify the implementation details of the design approach that should be used.
e. _____ Systems Engineering should include the customer and user as a part of requirements development process.
f. _____ When developing the System Specification, understanding needs is more important that just collecting assumed requirements from the stakeholders.
Q25. A user has a smart phone. It can navigate using GPS. It can make phone calls using cell phone towers. It can take pictures of objects. It can stream video from movie providers (e.g. Netflix.) It can deliver news from a news provider (e.g. BBC.) If the user breaks the screen, the user can take it to a repair facility to have it fixed. Draw a context diagram that shows the system and the external entities (people and systems.)
