Virtual Teams: How to Make Them Succeed

At this year’s Lean Transformation Conference in Tacoma, Washington, Arun Kumar spoke on the subject of “Virtual Teams: How to Make Them Succeed”.

A synopsis of the presentation:

Virtual teams can be as successful, even more so, than traditional (collocated) teams – but you need to understand how the project dynamics change when everyone can’t be in the same room at the same time. In this session we will cover the key success factors to building a high-performing virtual teams: how you can plan your work, run your daily standups, communicate, and share content. We will discuss the different roles and expectations of Project Leaders, Team Members and Visitors, and how people can juggle multiple projects at the same time.

The presentation was an hour-long, including Q&A; here’s an edited version of the talk (about 45 minutes long.)

Arun Kumar, on how to Make Virtual Teams Succeed

We will start to do IP blocking

Regrettably, we will start doing IP blocking to stop persistent spammers from setting up Kerika accounts.

We have seen a consistent pattern of misuse that goes like this:

  • Someone signs up with a sina.com email address.  Sina is one of the largest ISPs in China, but we don’t have any users in China for the simple reason that most of Google’s services are blocked by China’s Great Firewall, and Kerika has a tight integration with Google’s G Suite.
  • The spammer isn’t actually located in China; they are in Manila (Philippines) and come from IP addresses like 203.177.13.60
  • These spammers send out hundreds, sometimes thousands, of invitations for users from the qq.com domain to join their (spurious) Kerika team.
  • These recipients are all users of Tencent’s QQ messaging system, based in China. Again, none of them would be actual or potential Kerika users, since the recipients are all located in China.

The user impact of this spamming was relatively small: almost no one with a qq.com email address would reply to these invitations, but the conduct was a very clear misuse of Kerika and harmful to our reputation, quality and brand.

(Among other things, these spurious invitations would pile up in the thousands.)

We have decided, therefore, to start blocking IP addresses using Amazon’s VPC service (since we use Amazon AWS extensively on our back-end.)

This is a brute force method, and not ideal, but we were starting to get really annoyed with these folks.  We hope this doesn’t impact any of our real users in the Philippines; if you are affected, please let us know!

An update on our Google Apps Marketplace problems…

We are still working with Google on fixing the problem with the G Suite Marketplace that caused the Kerika product listing to disappear unexpectedly about 2 weeks ago.

Progress was slow over the holiday season because many Googlers were out of office, but folks are back in town and working with us on debugging the problem — which, as far as we can tell, is entirely on Google’s end and has to do with their back-end systems for managing listings on the G Suite Marketplace.
