Peace,
In the traditional sense, by "showpiece NOC" I mean a room designed for the purpose of having large situational awareness displays on a wall, network weathermaps and charts, alerting systems, composed of four or more big flat panel displays.
a) Without a change in processes you need to replicate some of that at home of every onshift engineer of your NOC. This might sound expensive but a single failure might cost you more.
b) But to be honest, most of the monitoring done by "a hundred of blinking red eyes in a monitoring room" should be replaced with data analysis, correlation tools, and automated alerts. Those don't look that awesome on the Instagram accounts of your marketing team but work better.
