Dedicated emergency notification systems -- such as those used by hospitals and universities -- are pricey and probably overkill for a community bank. But with a little creativity and basic data manipulation skills, you can put together a low cost, high tech system yourself.
First, be sure your employee notification records contain the appropriate fields: Home and mobile phone numbers, an SMS text message field, and personal email.
Next, store the information using tools that are "platform independent". Notification lists in particular should be portable -- meaning, you must be able to quickly extract a current list and then port it to a number of different platforms. Excel is probably the best all-around format for moving data between systems.
Finally, test your system two or three times a year to give your team some practice.
