When you then take into account that fewer applications are single-system, single-platform applications, but are instead networked with the capabilities of many different systems—and sometimes not even restricted to one enterprise—you can see how complexity can lead to problems. We know, for instance, that more than 50 percent of IT projects are ultimately not successful. Why? Because the complexity of the underlying infrastructure puts a huge strain on development resources. If you put fragmentation on top of that—as related to processes, skills and development environments—you have a very complex mix of issues to deal with. So although, yes, while emerging technologies are a help to the consumer, they can also be extremely challenging for IT to manage. Q. Is that why companies are increasingly addressing applicationmodernization issues? A. Legacy applications represent assets that generations of developers have worked on, and they embody tremendous innovation and investment. One number I’ve seen, from IBM market analysis and estimates based on IT industry consultant and other data reports, is $4.5 trillion in cumulative investment in software from 1995 to 2010 alone. We can’t squander this heritage. But sadly, 70 to 80 percent of the development effort taking place within mature enterprises is actually spent on maintaining existing systems. This preoccupation with “keeping the lights on” prevents them from reacting to new challenges and opportunities in an agile fashion. Reducing the amount of effort spent on maintenance by looking at your application portfolio and deciding what you need to concentrate on is very important. That’s why IBM has a focus on enterprise modernization solutions to help customers adopt a more

Let me provide an example: One of our customers, a large North American bank, conducted a very detailed analysis of its existing applications and was able to reduce the number of applications it had in service from about 600 to 147. That’s significant. You remove redundancy, you remove unnecessary complication, you allow your team to focus, you create critical mass for those applications that really make a difference and provide a competitive advantage—and you save money. Q. How does business agility address the issues enterprises face regarding their IT environments? A. Business agility is a term we use to describe the ability of an enterprise to deal with change and to make change work for them at a very rapid pace; to not only react quickly to changing circumstances but actually anticipate them. It doesn’t matter whether they’re new business opportunities that are propagated by technology, such as mobile development, or a new set of regulations; the question remains, can you react quickly? Obviously, you can’t be agile unless you pull people, processes and supporting technology together. That’s why we talk about multiplatform and collaborative development when we think about underlying technologies. That’s also why we talk about application lifecycle management. That’s obviously why we also talk about the need to look at a company’s software development and delivery processes and how to manage both risks and the existing investments for maximum business outcome. Q. Is coordination the backbone of business agility? A. It’s actually coordination, collaboration and integration. You must integrate technologies and teams. Very often, the skills and teams that you’re integrating not only span different roles like testing, development and business

incremental and continuous approach for modernizing existing software assets, skills and infrastructure. You need to be able to look at the entire portfolio to determine what is and isn’t differentiating. To stay competitive, companies must establish business priorities for IT investments. Our application portfolio management solution gives companies the ability to jump-start this process.
