Insider Insights from the industry Simplify What Matters Improving tools ultimately increases productivity By Scott Fagen and Edward Marootian Jr. n today’s world, where IT is being asked to do more with less—or do more with nothing new—focus must be placed on improving every aspect of service delivery: cost, time to value, and creating new, unique value for customers. At the same time, experts estimate nearly 80 percent of the IT budget is spent on “keeping the lights on.” How can IT innovate with only 20 percent of the budget? The answer is: work smarter, beginning with simplification. Simplifying tools, tasks and the environment reduces complexity, increases the velocity at which people can work or learn, and reduces the opportunity for errors. It targets high-value activities–maximizing the savings in time, effort and money. people coded their work offline, with meticulous desk checking, to ensure their programs would run successfully the first time. Over time, costs associated with computing hardware and software have declined substantially, while other costs like people, space and power have become less predictable. This shift in costs has been matched by a shift in burden. Does anybody still use a human operator to perform job scheduling? Not when the combination of the job entry subsystem and workload-automation products do the work far more effectively and less expensively. What would once have been considered sacrilege—spending “expensive” compute time on tasks that didn’t directly deliver a business I In the Beginning At the dawn of commercial computing, the price of hardware was prohibitively expensive, so machines needed to be kept continuously busy to recoup that cost. By comparison, people and software tools were more modestly priced. To best utilize the machine, service—is now the rule; it’s cheaper to have the system do the work. It’s important to remember what computers are for: to perform tedious, error-prone or repetitive tasks. While these points appear mundane on the surface, they point out an important trend: Simplification is often driven organically. The fundamental economics of computing drive the transformation; work moves from being people-centric to computer/process-centric. Advances in 18 J U LY/AU G U S T 2 0 11
