Naresh Ahlowalia has more than twenty years of experience in software development, software testing, and systems testing. He has worked on many different tools like Rational, Mercury, and McCabe. Besides commercial applications, he has worked on military and avionics systems. He has interests in all aspects of software testing, including automation and performance testing. He is experienced in waterfall as well as incremental and iterative lifecycle methodologies. He has developed an approach for analyzing and testing from use cases, called Use Case Path Analysis. This graphical approach helps determine the use cases flow problems and also derive test cases from the use cases. This technique has been effectively used in two projects at Fannie Mae. Both projects were successfully put in production and were finished on time and within budget.
