## Back to Basics: The Factory Pattern ## MIKE SHAH 2021 October 24-29 ## Please do not redistribute slides without prior permission ## Software Design: Factory Pattern Mike Shah, Ph.D. @MichaelShah there is a common pattern that can help solve this problem--the factory design pattern. In this talk, we are going to discuss a creationally designed pattern known as a factory. The pattern can be as simple the factory pattern, and discuss which scenarios you may not actually want to use a factory. Attendees will leave this talk with the knowledge to go forward and implement the factory pattern, as well as
