At SmartBear, we specialize in software tools designed for developers and testers. So we were a bit surprised to see our enterprise-level peer code review tool, Collaborator, being adopted by professionals who have nothing to do with creating software. Turns out, they are using it solely for the purpose of reviewing Microsoft Excel docs. After reflecting on this a bit, it actually makes a lot of sense. Why shouldn’t spreadsheets—which can often be as complex as software in design and implementation—be subject to the kinds of peer review and quality processes that other enterprise deployments are subject to? No technical leader would question peer code reviews for software at various phases before a project deployment. Critical Microsoft Excel spreadsheets should not be treated any differently!
