TIO is a management practice which consists of running a company through a collection of Web based services and online applications in order to reduce costs, lead time and overhead. Although they might not be aware of it, young entrepreneurs who use Google Docs to write and share office documents, Hotmail to communicate by email, Skype to call, Basecamp to manage projects, Salesforce to manage customers, Linkedin to manage their staff, Google Desktop to search through corporate information, Lokad to optimize their inventory, Onlineformapro to train their staff, Marcaria to file patents and Entreprisefacile to print and deliver snail mail are actually typical early adopters of TIO.

With no servers, no software and no IT staff, they benefit from an information environment which is more productive, more functional and more advanced than the one of many large companies.
