Google GSuite and Office 365/Exchange coexistence in 8 Short Weeks

Why care about G Suite and Office 365 Coexistence?

As an organisation’s digital workplace evolves, it is a best practice to segment employees into ‘personas’. Each defined persona will have a different set of tools that they will require to perform their job. For many employee personas G Suite may make sense over Office 365. For example, the next generation of employee talent has ‘grown up’ with Google and they are most familiar and productive with G Suite. Since Google owns roughly 70% of the education market, many fresh grads have never even used Microsoft Office. To attract the best talent, organisations will need to offer certain personas a choice of tool. G Suite and Office 365 will need to work in harmony. In addition, a dual vendor strategy makes sense for productivity tools since it represents a significant spend. Create competitive tension with Microsoft by introducing G Suite into your environment.

Week 1: Collaboration and Messaging

At the end of week one we will have the basic configuration of G Suite completed. This includes all of the productivity applications except Gmail and Calendar. In scenarios where integration with Office 365 is not required for email (e.g. use of a different domain from Office 365) the end of week one configuration will also include basic mail flow and Calendar. Also included by the end of week one is the on-boarding of up to 50 early adopters. We typically recommend that early adopters come from the IT group, or select employees from lines of business who are comfortable being technology early adopters. Lastly, in week one we will work with your organisation to develop POC success criteria.
