What is the purpose of the speech?

Thank you, thank you.. I feel truly honored by this award for employee of the year here at Flint and Gray Banking. At the beginning of the year, I was asked to develop a mobile application for our account holders that would track their bank activity and give them a summary of their spending trends over time. After ten months of trial and error, we are now able to release a fully functioning application to our users. But I couldn’t have done it without my team of programming specialists. They all did a fabulous job. So for that, please join me in giving them a warm round of applause. Come on up here, everyone!
