Quality in Front – From a Mainframe Mentality to Agile

November, 2023

The November 2023 tech talk was presented by Dave McKenna

Abstract

What do you think of when I say “mainframe”? Most think of a giant, lumbering dinosaur. If I ask you what animal you think of when I say “agile,” most folks respond with “cheetah.” My challenge at CA Technologies/Broadcom was to make that dinosaur more like a cheetah – or to at least make it dance a little.

The challenges were many. It’s no secret that most folks with mainframe knowledge and skills are getting close to retirement age. New mainframe developers want to use modern tools to work on the platform. This can be a challenge because historically, the mainframe has used very different tools and programming languages than what is used in non-mainframe development or even what is taught in colleges and universities. Testing and quality practices didn’t include much in the way of automated testing. Almost all testing was done manually. And DevOps was unheard of….

In this session, I will talk about what we have done to address these situations with agile and DevOps practices to substantially increase the quality of our products while increasing value to our customers.  Today, we are the “Dancing Dinosaur.”
