Why We Do It? We care.

At OSI, we care about our clients, we care about each other, and we care about producing great software.

CLIENTS — We admit that the organization we most want to see succeed is our own. But we’ll quickly acknowledge that we can’t win unless our clients win. There’s no way around this symbiotic relationship. Fortunately, at OSI, we genuinely love to see our partners have breakthroughs in top-line growth, innovation and efficiency.

TEAM — If you’ve ever experienced the excitement that comes from being part a high-functioning team, you’ll understand why people matter. Trust. Accountability. Purpose. Self-confidence. These are all part of that exhilaration, but the whole is more than the sum of its parts. Great teams can get you through the tough times and can unlock greater potential than a group of individual contributors ever will.

PEOPLE – We care about individuals and humankind. That’s why we invest in talent and push people to do their best work. That’s also why we have given colleagues help when they’ve encountered personal crises; paid for surgeries people couldn’t afford; funded capital improvements and arts projects to improve our communities; and closed the office to attend colleagues’ weddings.

SOFTWARE – We care about the code that we write. We take pride in it. We constantly try to improve on it. We adopt best practices when they suit us. We geek out over data and make it work for us. We are not afraid to try the latest & greatest and to support the last year’s. We are ready to make mistakes and learn from them. We know that building great software requires a lot from us and we committed to it.
