The Microsoft Skype Operations Framework (SOF) provides a set of comprehensive & practical guidance for customers to deploy Skype for Business Online with Office365. This framework was derived from traditional service management methodologies but built to specifically focs on Skype for Business Online. In the initial Plan phase of the SOF, there is a network essentials assessment which must be conducted to determine if the customer's network is able to meet the requirements for an optimal experience with Skype for Business Online. The Network Assessment involves several components including completing a questionnaire, creating the personas and calculating bandwidth requirements. This blog post will not cover all the components but focuses specifically on how to use the Network Assessment Tool that Microsoft recently updated to perform the necessary network tests to determine if the requirements are met and identify any potential network issues. The tool itself is free, easy to run and can be downloaded here https://www.microsoft.com/en-us/download/details.aspx?id=53885.
