ArticlesSLAs Simplify Support
June 17, 2019
Service-level agreements (SLAs) were nearly nonexistent when I started in IT.

ArticlesClearly Defining Project Completion
December 1, 2018
My first contract as an independent consultant was with a large, multinational bank. They were attempting a processor-to-processor application that exchanged banking information nightly, and trying to implement a new IBM function called IBM Advanced Program-to-Program Communication (APPC)—something new to them, but not me. I was initially delighted to take the project. I met with […]

To successfully drive adoption of DevOps on the mainframe, IT […]
