Re: Complexity killed the cat
You have to remember different generations have different communication and collaboration needs. Millennial will make up over 50% of the workforce by 2020 and they were brought up with technology always on generation with the ability to use multiple instant communication methods. They are not interested in email as it is too slow.
Product like Teams although not perfect are bringing that multi modal communications into the work force. Without products like this then people resource to Whats App and other consumer based applications to conduct corporate business which results in data outside the organisations control and a GDPR nightmare
