A new report by Retail Banking Research (RBR), states tgat 56% of automated teller machines (ATMs) in Western Europe had beenconverted to run on the Windows operating system by the end of 2005, a
figure that RBR estimates has now risen to 64%. However, Level FourSoftware warns that for banks that have not considered their ATM testingand deployment strategy from the outset, the costs of this migration arelikely to be outweighing the benefits. Following the move by these banksfrom the OS/2 platform to Windows, in Level Four’s experience, the overallstability of ATMs on the high street and subsequently the customerexperience, have suffered.

“Undoubtedly Windows-based ATMs are the future, yet many banks have found that the migration path has proved far from smooth,” said Martin Macmillan, marketing and business development director at Level Four. “Customers are used to reliable ATMs and will not tolerate poor service. Banks must get their testing procedures perfected, if they are to operate atrouble-free ATM network and maintain customer loyalty.”

The scale of testing needed for Windows ATMs has proved challenging,especially considering a full regression test can take banks two to threemonths to execute. A test is required each time a software release occurs,which can now be as frequent as once a month. In addition, tests are necessary when changes are made to other applications running on the ATM, and retesting must also be carried out after every Windows security update. This rigorous process is required because the ATM software application itself, as well as every interaction between the other applications in the
software stack, must be tested to ensure stability.
