Take, for example, a company adopting a mechanism to control all monitors and computers, so they can be placed into a low-power consumption mode (such as shutdown, hibernation, or standby) when they aren't being used. Imagine that this company is also building an application that a few users will access via their PCs to update the state of alerts affecting a core business service The business analyst in charge of capturing the requirements for the alert system would have to 48 (1) investigate the potential impact of a delay caused by the need to recover the computer from its energy-saving state before the application could be used to update the status of an alert. The BA would also be responsible for discussing with the stakeholders the expected system behavior under these circumstances. A decision could be made stating that a user returning to her desk after taking care of an event that triggered an alert should be able to access the application within 5 seconds or less, to post an update. As a consequence, a non-functional requirement could be created establishing that "once an alert is issued, and until it is resolved, the application will prevent the workstation from going into any energy-saving state that requires more than 5 seconds to reverse
