Well, you might want to add that along with enough lifeboats for everyone, Titanic also inspired the need for manditory lifeboat drills so that everyone will know where to go in case of an emergency.

I do not think it was totally tied with the Titanic, but more inspired because of, ships today have Personal Address systems (intercoms) to let people know that something is wrong (unlike Titanic, which had to rely on her stewards and such knocking and banging on people's doors, which too a lot of time!)

In Titanics younger sistership Britannic, they installed a tube that could take messages from the marconi room to the bridge and back. That way, the bridge could get the ice messages promptly and not have the operators delay or not take deliver them at all. To make it short- Titanic inspired more importance to getting wireless navigation messages to the commanding officers.

The shipyard that built Titanic (Harland and Wolff), recalled Titanic's sister ship Olympic from service, and stopped construction on Britannic, to reconstruct their watertight compartment systems. I'm sure shipbuilders all around the world looked at what went wrong with Titanic and made notes to inprove their ships.

Titanic had weaker steel than todays ships. But the steel we have today is more due to technology rather than a result of the disaster. But...maybe you can work it in if you need to fill some time!

Please read about these points yourself and you may find some other info yourself, but I hope this gets you started.
