Previously I have focused on build performance in posts like Speeding up the pipeline by slowing down builds and Rethinking personal builds, but there is a lot more to a continuous delivery pipeline than build times.  Once a build produces artifacts, you need to do something with them.  Often the next step is to install […]

I have worked for IBM for about 20 years, moving back and forth between development, customer support and IT operations roles. Working in these different roles helped give me perspective for my current role as the manager for Jazz Continuous Deployments/DevOps. In this role I am responsible for ensuring that our multiple staging and self-hosting […]

This is the second article about testing in our Continuous Delivery series to share practices we have adopted in our own development team within Rational Team Concert (RTC). The presented techniques are used to control software evolution and to improve the quality of our code base. Since there is a variety of IBM and open […]

In my first post, I described how we were able to increase parallelism and significantly improve the end-to-end build time of the Collaborative Lifecycle Management (CLM) pipeline.  This has provided value in many ways, but as Pete Steinfeld pointed out in his Accelerating CLM builds post, it doesn’t do much to improve the developer experience.  […]

The following is the third posting in my Collaborative Lifecycle Management (CLM) Continuous Deployment series of blogs on Jazz.net. The earlier two blogs can be found at Improving throughput in the deployment pipeline and Behind the scenes of the CLM Continuous Deployment pipeline. In Behind the scenes of the CLM Continuous Deployment pipeline, I had […]

In a recent blog post, Pete Steinfeld casually mentioned that over the past year the time to build the full Collaborative Lifecycle Management (CLM) pipeline was cut in half, but didn’t elaborate on how that reduction was accomplished.  Since I was involved with analyzing and improving the pipeline, I thought I would share, at a […]

Rational Team Concert (RTC) has started releasing quarterly. Since large features rarely fit into such short cycles, we’re making heavy use of RTC’s branching and merging functionality. That could result in merge hell, but it doesn’t. This post will give you an idea of how the RTC team uses our own source control management system, […]

The following is in continuation of the work I described in my previous blog posting at Improving throughput in the deployment pipeline. In my earlier post, I briefly described how the IBM Jazz Collaborative Lifecycle Management (CLM) project team is developing a deployment and test execution pipeline that is allowing us to identify key product […]

Since August of 2012, we’ve been working on improving our ability to continuously deliver software. Our work was organized into four different, but overlapping areas — ways of working, continuous deployment, build, and test. The team that I work with is focused on build, the process by which we transform our source code into artifacts […]

History I work as the Automation Lead for the Function Verification Test (FVT) team in the Collaborative Lifeycle Management (CLM) project. This post details some of the efforts we are making to improve our test automation to enable continuous delivery. The CLM FVT team created the CLM Build Verification Test (BVT) scenario to quickly sanity-test […]
