Great Course, Great Instructor, Great all around!
This course was great and John was an awesome instructor! The explanation of materials to cover BEFORE the course helped a great deal. I took my exam on the first try and passed. This isn't just an exam prep class, but helps the learner to understand how to APPLY the materials in the real world. I strongly recommend this course to anyone and don't forget to read the materials before the start of the course so you can be fully engaged in the class.

PSPO-Advanced Remote Learning
It was great to be able to continue my learning journey in Scrum during a trying time such as we're facing with COVID-19. It was already a challenge to be able to find this course near my area. Now I was afforded the opportunity to attend remotely. I was very impressed with the collaboration tools we used, and I feel very much like we still got close to the same amount of value collaborating this way as if we had attended in person. John is a great instructor and facilitator of conversations, and I highly recommend this course to anyone who is looking to become a better Product Owner, Scrum Master (coach), trainer, and/or Agile Coach!

Amazing and very informative course
Amazing and very informative course. There was just the right amount of content mixed in with discussion and exercises to be engaging throughout. The additional resources and ability to reach out and engage with the instructor/community after the course for further insight also is greatly appreciated. Originally, I was skeptical to the virtual training vs Live In Person, but I feel I got just as much out of the class as I would have if it had been in person. Great work! Thank you.

Scrum Master Virtual Training
I had the opportunity to take a virtual Professional Scrum Master class conducted by John Gillespie and it was very interactive and informative. John didn't miss a beat with sharing all of his knowledge and creating a trusted learning environment where all class attendees felt comfortable participating and raising questions. I would highly recommend taking John's class whether they are classroom or virtual in nature. I feel like I have the tools necessary to pass the PSM assessment and utilize the knowledge gained in my current role.

If anything, I'll recommend his class to anyone.

Draw from a wealth of experience with a great instructor!
John was a great instructor with tons of experience to draw from in the class - giving real life examples of scrum in action within an organization as well as the challenges that scrum masters face. I was in a small class, but it was highly interactive, and gave us the ability to ask questions about how scrum could be applied in our work contexts. The exercises we did in the class was invaluable to truly understanding what it means to be a scrum master and the types of situations you would face in that environment. I would recommend this training to anyone serious about DOING the actual work of enacting scrum within an organization or team. The class beats anything you can simply read from the book, and it was a truly enjoyable learning experience.

John has very rich experience in his profession that he brings to the class and keep the curriculum it on track for two days.

PSPO
Very informative, hands-on learning; course was extremely applicable to me as a product owner. Would prefer to have the course be a multi-week, one day a week course to allow myself to put learnings into practice instead of a brain dump where some concepts may be lost in the future. Would also like more info on how to become certified, and market data on what the best orgs are to be certified through. Overall great course, would highly recommend.

This was a good class
This was a good class. Our instructor John was extremely experienced and seasoned in the field, which helped him to understand all of our companies and the unique challenges that we face. As our company has been transitioning to Agile, I have felt very confused about the why and how, and our Scrum leaders have done a terrible job explaining it to us. So, it was great to have John clarify everything. I understood Scrum and Agile better after 2 days in this class than I have from months of trainings at work. It also helped me understand how UX fits into Scrum. John knows that every company is different and you can't be overly firm in your definitions or rules of Scrum. It's not meant to be an omnipotent system. I think it was more expensive than the value what we got out of it, hence removing one star. However, as far as the class itself went, I can't imagine a better instructor or much that could have been done in a different way.

The question remains as to why managers continue to plan projects based on sequential assumptions.

When an organization decides to embark on an Agile Transformation, the first question should be, “Why?” What does leadership hope to achieve? Will the chosen path lead to improved ability to deliver high-quality business value? Once the goals of the Agile Transformation are identified, leadership should consider something that Ken Schwaber, co-creator of Scrum said over five years ago:
“I estimate that 75% of those organizations using Scrum will not succeed in getting the benefits that they hope for from it . . . Scrum is a very simple framework within which the “game” of complex product development is played. Scrum exposes every inadequacy or dysfunction within an organization’s product and system development practices. The intention of Scrum is to make them transparent so the organization can fix them. Unfortunately, many organizations change Scrum to accommodate the inadequacies or dysfunctions instead of solving them.”
If your teams are bolting on a few Scrum events such as the Daily Scrum to an iterative waterfall software development lifecycle without understanding and embracing Scrum core values, it is a safe bet that you will not achieve the business agility envisioned at the outset of your Agile Transformation.
Is the organization adopting an “Agile-ish” approach as opposed to an Agile Transformation because mid-level management does not want to trade “command and control” with servant leadership? Does middle management believe current processes have already been optimized and that there is no need for continuous improvement? Or is the failure to implement Scrum related to fear of change and transparency?
Having a team perform waterfall iterations is not a reasonable facsimile of an Agile approach.
How many of the four foundational values from the Agile Manifesto[1] does an iterative waterfall approach embody? How many of the 12 principles[2] does it employ? Few if any, as most iterative waterfall teams still apply a significant upfront design phase. An iterative waterfall-based project plan measures progress via arbitrary milestones that do not typically include delivering working software to stakeholders.
When is the last time you attended a program review meeting where everything was stated as “GREEN” though no evidence of working software or customer feedback was provided? “GREEN” is of little consequence without delivering working software. Does “GREEN” mean that you failed to identify “RED” feedback? Is this lack of transparency willful misdirection? Scrum, in contrast, would highlight the deficiencies as they are encountered while delivering a working product increment each Sprint. This real-time feedback provides information while there is still time to act on it to improve the project. An Agile-ish approach may give you some insight at the time of a post-mortem, but that doesn’t allow for any course adjustments in your current effort.
So, have you succeeded with your Agile Transformation or have you “Kind of… Not”? Have you decided not to address the organizational impediments that the Scrum framework makes visible? Now may be a good time to revisit the reasons for initiating an Agile Transformation.
