  1. “Error in coding” … AT&T has again demonstrated they lack the requisite procedures, processes and discipline when running a technical organization. This demonstrates again that AT&T lacks the requisite procedures not only to control who and when changes are made to a “production” or “live” environment. “Best practice” organizations tests any changes being made to a “production” environment, testing the changes “beginning to end” to ensure no unexpected changes will take down or make the “production” environment inoperable or degradate the service levels. And in the event that after all the testing, a problem does occur, you should have a pre-tested “roll back” process and procedure that you have tested in advance to enable a business to restore the “system” back to its previous settings and code configuration. Clearly AT&T management had none of the procedures, processes nor discipline in place which negatively impacted the service levels of an unknown number of customers. Thank goodness there were no serious medical situations that required telecommunication services to work.
