Our Thoughts On


Big Problem: Inefficiency In Data Extraction And File Conversion.

Big Thinking: Use Proprietary Software To Do What Once Took Days In Just Hours.

Shareholder TED PETTKO has extensive experience with public and privately owned companies from a diverse group of industries, and he’s been with Schneider Downs since 1997.
Ted's team implemented a solution for a client who had an ongoing need to extract data from one platform and enter it into another. The manual process they had in place was not only cumbersome and time consuming, but it also resulted in an unclean format. Using proprietary data analysis software, IDEA, the team helped the client extract an entire year of information into a clean format in a matter of hours. Previously, it had taken the client several days to perform the extraction. "Our efforts on behalf of our client enhanced their timeliness and efficiency," Pettko said. "Using data analysis software in the audit profession gives us the ability to extract information in a fraction of the time, summarize the data and produce high-level analytics to support our audit opinion. Ultimately it's a win-win." Schneider Downs provides Big Thinking and Personal Focus in delivering a variety of services for large and small businesses, both publicly and privately held, as well as nonprofit organizations, government entities and more. Through our commitment to thought leadership and knowledge management, we deliver the solutions our clients need with a personal commitment to service.
