There may be an app your Team frequently uses. For the purpose of this article lets take this app to be Microsoft Flow where the Team is repeatedly adding Flows between apps such as Forms and SharePoint and Twitter and Powerapps across multiple Teams. They could always add Flow as a Tab to a particular Team, but with the increasing amount of Teams this wouldn't make much sense as the Team members would have to remember what Team, or - as is more likely - they are now adding Flow Tabs across multiple Teams which is littering Teams with Tabs which don't necessarily need to be there.
In my personal experience, it is not just IT Pro's who want to keep up to date with roadmaps and have an understanding of whats coming to the platforms they manage. Enthusiasts and evangelists are often eager to see new features that they may be able to leverage or rave about to their partners and customers. Support always wants to know what's coming down the pipe in order to prepare for what they see are inevitable issues. Finance loves anything which can lead to greater ROI and save money - and CEO's often like to know they got it right.
From time to time it's important to get feedback to the Team. Within the Team itself this can be done in several ways. Two examples are Polly - the app which allows the pollster to snap poll members of the team, as well as Yammer Q&A's via a Yammer Tab. However, today we'll focus on feedback from outside the Team and getting feedback to the Team. An effective way to do this is with Microsoft Forms. Microsoft Forms is a simple, lightweight app that lets you easily create surveys, quizzes, and polls. It's a very popular app - very pragmatic and meaningful, yet its also a young app. It means that it still has a long way to go and a lot of development needs to occur for it to have parity with competitors such as SurveyMonkey.
