Energy Transmission Control
For Hydro Quebec NCC (Network Control Center) is
the brain center of the company. Cognitive Group
had already worked with Hydro-Quebec on designing
the user interface for some of its subsystems. Such
system are very complex and some could cost up to
$2 billion. Based on the success and results of
our earlier work, Hydro Quebec selected us to redesign
the user interface for the critical CME control
system.
If you
put this design in my hands, I will postpone
my retirement.

are professional, they have a structure aproach
and they know how to design.

| Before, the system requires more than
5,000 screens (page views) and 10 main Subsystems
such as FREQUENCIES CONTROL MANAGEMENT (RFP), OUTAGE,
and TRANSIT LIMIT SYSTEM (LIMSEL). The main difficulty
facing the dispatcher is accessing the right information
rapidly. Often, the dispatcher must navigate through
more than 20 screens of information in order to
understand an event. In an emergency, the dispatcher
is left guessing. |
After, having
spent more than six months filming Hydro Quebec
in the NCC, then transcribing and performing cognitive
task analysis, we were able to achieve a complete
redesign of the system. Our redesigned system reduced
the number of screens from 5000 to 475.
All primary information is visible within on page
and all information can be accessed within two mouse
clicks. In an emergency the dispatcher can instantly
access the right information.
