5 Must watch videos for every Scrum Master

As Scrum Master, it’s expected from you to be a teacher, mentor, coach and change agent in an organization. Videos help to teach the teams and organization about Scrum, Agile and related subjects.

In this edition, I selected videos about personal behavior, motivation and creating a positive working environment. These subjects are important for creating high-performance teams.

Certification Authority Authorisation

Certification Authority Authorisation (CAA)

Certification Authority Authorisation (CAA) allows a DNS domain name holder to specify one or more Certification Authorities (CAs) authorised to issue certificates for that domain.

Which means that a CA will check the authorisation before issue-ing a certificate.
This article also describes how it works and how to configure this for your domain.

Zebra Spidr

A SPIDR for the Agile Scrum team

Everybody knows the problem that a User Story is just too big to handle for a Sprint. Just cutting the User Story in smaller pieces is not the way that most of the time works. SPIDR might come in handy.

Three Little Pigs

Three little pigs – Fun Retrospective Technique

This article is about the Scrum Retrospective Three Little Pigs and my personal experience with it. How to and the extra benefits of this retrospective. The goal I had with the retrospective, was to look back at the past sprint, but also to talk about what goes well (bricks); what goes well most of the time, but needs improvement to get impediments out of the way on structural basis (sticks); or what subject needs further improvement (straw).
