In my previous blog (Going Agile), I identified the need for executive sponsorship in order to transform into a business agility model. When you hear of Agile software development, some of the first thoughts that come to mind are Scrum teams and Sprints. But did you know that there are Agile frameworks besides Scrum, such as Kanban? What about Scaled Agile Frameworks? Before you begin the journey to Agile, you first need to know why. Agile … [Read more...]

How do you change a waterfall software development culture that has been in existence for decades to begin using Agile?  That was what I asked myself when I took over product development of Compuware’s Mainframe Solutions last spring. I began working with the leaders of Product Management and Development to define a 24-month plan to transform how we delivered our software.  Later that summer Compuware hired a new president for our Mainframe … [Read more...]

Discussions about the mainframe’s future often center on the need to replace operations staff. But the most pressing challenge mainframe owners face at the moment isn’t operations. It’s protecting and extending the incalculably valuable intellectual property residing on their mainframes in the form of application code. That’s why IT leaders should aggressively prioritize modernization of mainframe application lifecycle management—and not get … [Read more...]

Marginal cost is of paramount importance when it comes to the economics of IT.  As your business grows, after all, IT will have to support more applications, more users and bigger workloads.  If your marginal costs for doing so are high, your growth will be painful and expensive.  If your marginal costs are low, your growth will be easier and more profitable. Marginal costs in distributed computing environments, however, are nightmarishly … [Read more...]

John Marzluff is an ornithologist and a professor of Wildlife Science at the University of Washington. In his new book Subirdia, he discusses his study of what happens to the suburban bird population as their landscape changes underneath them—for instance when a wooded area is cleared for new housing, shopping or golf courses. One surprising finding is that bird diversity actually increases in the new environment. Another finding is that the … [Read more...]

Companies greatly value their intellectual property.  They devote considerable effort and money to protecting it.  They contractually obligate employees not to compromise it.  And if they discover that a competitor has usurped it, they pursue legal redress with the utmost intensity. Yet many companies neglect some of their most valuable IP: the business logic coded into their mainframe applications. Worse yet, if they’re not careful, the … [Read more...]

Some mainframe sites have already initiated projects to migrate to IBM COBOL 5.1 in hopes of reaping the millions of dollars in CPU savings that come along with the compiler, the first to truly exploit the System z architecture. Other sites are deep into research projects to scope both the effort and the benefits of this migration. For the practitioners charged with these migration tasks, this is one of those classic first-do-no-harm … [Read more...]

There's a lot of talk and hype about Big Data and with that comes confusion and mistakes. Here are five big mistakes you can make when starting a Big Data initiative. Ignore the source of your data.
