I've been in the Software business for over 25 years. I started working with dBase3+, moved to developing using Clarion, and continued on to C#. For the majority of this time, we developed software using no recognizable software development lifecycle (SDLC), instead either just grabbing a requirement (if we were lucky) and coding it, or just making it work the way that felt right.
In my last job before exposure to agile practices, I worked in a shop which was strongly grounded in the waterfall SDLC, and then mutated to a semi-iterative waterfall process.
My career in Agile practices began when I was promoted to Manager of Software Development for a software contract at the Kennedy Space Center. I was charged with transforming us to an agile shop. After CSM training with Jeff Sutherland, I began this work and, in three years, we'd built ourselves up to six Scrum teams, a Kanban maintenance team, and a large number of very satisfied customers. I functioned as the Evangelist at the Center, starting the Scrum User's Group and briefing both corporate and KSC leadership on Scrum.
I am currently the Manager of Application Development and Data Management for Health First, a healthcare integrated delivery network in Brevard County, FL. This is another shop where the transformation from waterfall to Scrum is underway.
Abacus Technology Corporation, ScrumMaster/Organizational Scrum Evangelist
August 2010 - August 2013, Kennedy Space Center, FL, US
Since October of 2010, I've been the organizational (and perhaps KSC) Scrum evangelist. Promoted to institutionalize scrum and get us doing it "right," I attended Certified ScrumMaster training, taught by Dr. Sutherland in Cambridge. I've since become a Certified Scrum Product Owner.
In my role, I've operated as an organization scrum coach, and have been SM and PO on several projects. I've been involved in the selection of a project system to manage scrum projects (Jira), and have worked to get the organization formally trained in Scrum.
