That external validation, both from certifying bodies and from peers, colleagues, teachers and students is a crucial part of the scrum and agile community, Johnson says.
"You need to keep records and documentation of people you've worked with, people you've coached, trained and mentored. You should have evidence of your contributions to the scrum community; teaching evaluations from students, your coaching and teaching materials and you have to know the scrum guide and the agile methodology inside and out and how to apply it in the real world," Johnson says.
An exclusive club
The process to become a CST is lengthy and rigorous, and it's exclusive: there are only about 190 CSTs worldwide, of which only about 20 are women, according to Johnson.
Johnson's path to becoming a CST has been long and winding, but there are myriad directions to take her career from here, and that's what's most exciting, she says.
"I absolutely love what I'm doing, and I never want to go back to that 9-to-5 employee type role again. I'm running a business, I'm teaching, I'm helping others make that transformation. But if I wanted to, I could go into a private organization as a CIO. I could be in upper management. I could start a consulting organization, I could even be in human resources or higher education, if I wanted to. The possibilities are endless," she says.
