In the Collaborative Lifecycle Management (CLM) project we have declared three imperatives for improvement in order to increase our agility with a goal of continuous delivery: culture, process, and tools. Of these three things, culture is, in my opinion, the most difficult thing to change because it’s less tangible than processes and tools and because culture […]

You have probably heard about DevOps but you want to cut through the hype and understand more about this approach. That is the genesis of DevOps for Dummies, authored by IBM’s Sanjeev Sharma. It is written to appeal to both practitioners and managers and to show you how you can apply a new DevOps approach […]

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 […]

“I have edited the files you wanted me to look at”, I told a team member over coffee. “I will check them in once I finish this cup.” So, after I was back, I opened the pending changes view in the Rational Team Concert Shell control panel, and began to check in the changed files. […]

“I have delivered some new files to the stream”, said a teammate at our morning scrum. “Can you please edit them?” We’re agile.  I promised to return the files within three working days. Then, I grabbed some coffee, opened Rational Team Concert Shell, and tried to remember what it was that the task bar icon […]

“It can do source control management (SCM) stuff. It is almost like the Rational Team Concert client for Eclipse IDE”, I was told, “but simpler.” “Aha! A margherita”, I thought and, being of a nature that prefers bare bones over raiments, I downloaded and installed Rational Team Concert Shell (I’m using version 4.0.2) with the […]

One of the advantages of using the SCM capabilities of Rational Team Concert (RTC) is the traceability of change sets across multiple streams and workspaces. When a developer completes a new feature or fixes a bug, they deliver one or more change sets to their team stream. These change sets can then be accepted into […]

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.  […]
