This week's developerWorks newsletter intro shows you why maintaining your software apps is a bigger deal than you might imagine. Not subscribed? Sign up for your customized newsletter today!
Let's talk software maintenance in mainframe applications. OK, maybe it isn't the most tantalizing IT topic around, but before you run screaming to the latest mobile-social phenomenon, consider this: Software maintenance can absorb up to 70% of an IT budget, and managing change can help you shorten your maintenance cycle, reduce risk, ensure high quality, and thrive in a challenging economy.
Are you with me now? Good. Now take a good look at our new three-part article series on managing change in mainframe apps with Rational Asset Analyzer. Author Amy Silberbauer shows you how to effectively identify assets that will be affected by the proposed change (Part 1), how to analyze the impact of changes to manage scope and risk (Part 2), and how to customize, aggregate, and share the results of your analysis (Part 3) -- all of which will help you prepare for the next phase of the lifecycle: implementation.
Trust me, you'll be glad you stuck with it. And your friends and colleagues will swoon at your newfound expertise. Go ahead, tweet about it.
Until next week,
John Swanson and the developerWorks editorial team
