I attended the Kanban System Design training earlier this week. The course was well-structured and David had a lot of previous experiences to draw from. This allowed us to reflect on our current system processes and look at how applying Kanban processes over time would help to control our flow of work.

I attended the Kanban Flow Manager course facilitated by David. I'm so glad I did. David is super knowledgeable not just about Kanban but on Agile, Lean amongst other topics - which added depth to the session. I walked away with practical solutions to my long-standing workflow issues which I can implement straight away. Moreover, thanks to David's amazing facilitation skills, I've really understood how to leverage metrics to help guide my teams to improve flow without increasing stress. Understanding CFDs and lead time distribution charts is one thing, but I got to experience first hand the power of how to leverage them as a narrative building and coaching tools. I would highly recommend this course and David as a facilitator.

I am very happy with the training I received. The trainer was very organised and knowledgeable and his style and pace suited me perfectly. The balance between lecture style learning and group activities worked well and the virtual format was smoothly managed.

I've attended both the Professional Scrum Master and Professional Scrum Developer courses taught by David and have nothing but good things to say about them. His attention to detail and enthusiasm for Scrum and its implementation shine through in his courses. The sessions are thought-provoking and really do help you gain a better understanding of how Scrum works and how you can use it in your current role. David is also a great coach, he is patient and has a great sense of humour which really helps create a fun learning environment. If you are considering Scrum Training, I can't recommend Red Tangerine enough.

David is an outstanding trainer, coach, and facilitator with an impressive depth of knowledge and experience. I’ve attended multiple Kanban and Scrum courses facilitated by him, and each session has given me a clearer, more actionable understanding of how I can support the teams I work with. His insights have directly helped me improve our team’s collaboration and workflow efficiency. David is incredibly generous with his time, ensuring every concept is thoroughly explored in a way that makes it easy to grasp and apply. Thanks to his guidance, I’ve implemented several techniques that have had a tangible impact on our effectiveness. Whether you’re new to Scrum or Kanban, or simply looking to enhance your skills, I can’t recommend David highly enough. His courses are a must for anyone serious about improving their understanding and achieving real and lasting improvements.

Amazing! David's Kanban trainings are an eye-opener: I feel that in his field work, he combined his background as developer and physicist with his knack for understanding context and motivating people, to get a deep understanding of the principles behind Kanban, on an organizational, a psychological and a logical-mathematical level. After years of practicing Kanban, his KMM class showed me the Kanban practices, and how they build upon each other, from a totally new perspective. Like learners of a new language are thrilled when they get to string words together by using grammatical flexions and syntax, I am happy because David's didactical skills enabled me to make a big leap forwards in "Kanban's grammatical syntax", in this really intense but fun class.

Excellent Advanced PO Training David was an excellent teacher, the content was well structured and relevant. The activities really helped the group explore the real world PO role and the tools PO’s have at their disposal when it comes to maximising value. Would definitely recommend to any agile practitioner!

I attend training for two courses - Kanban System Improvement and Kanban System Design which together are the Kanban management Professional Qualification. Across the 4 days my trainer David was engaging, articulate and as a change manager the course has opened up a plethora of new conversations we should be facilitating at team and organisation level.

I learned so much from David Spinks. I especially loved the simulation, case studies, and the discussion of the metrics. David's teaching style of combining theories and his own experience was very helpful in the learning process. I would recommend him to anyone who would like to deepen their knowledge in Kanban and Agile in general.

I attended the KMM class from Kanban University over two weekends and it was by far the best online training I have ever had. It was very interactive and David was happy to share his vast experience with the cohort. Looking forward to the doing this all over again for the KCP class in a couple of weeks.

Basically in 2 weeks we went through Kanban System Design and Systems Improvement trainings in a remote class with people from the whole world, all of them put together by Red Tangerine. A great experience and I’m glad the facilitation wasn’t counter-Scrum or any other method. Thank you, David Spinks!

The course very informative and had lots of insightful training material. It made me much more aware of what Kanban has to offer. The trainer was excellent and made the learning fun. Would recommend.

David’s facilitation of the training was simply great. The use of whiteboards, discussions, games and quizzes reinforced what was covered in the lessons. KSI’s contents are especially useful and relatable to my current team situation, triggering me to think about how I can help the team to improve. As a newbie to Kanban, 6 months into practices, the notes I took from the training are always a great help when I need to revisit some of the principles to improve the flow to achieve even better effectiveness and a happy team.

A very informative and useful course. Loads covered in a short period, with a hands on, practical approach. Amazing trainers that are making the whole experience easy and unique

I had the delight to attend the PSK training delivered by Red Tangerine. I found their training to be highly engaging amd their breadth of real-life experience was the best part which made the exercises and learning relatable to real challenges teams, leadership teams, and an organization faces in complex environments. The flow of the course was a great blend of group work, mini lecture segments, and a tonne of fun. Subsequent to the training there is a supportive network of people that have undertaken many Scrum amd Kanban courses with Red Tangerine that help with follow up engagements on their online channels. I look forward to pursuing the Kanban Maturity Model and Kanban Coaching courses with David. He is a fantastic educator and is passionate about Agile and making a world a better place. If you're looking for a highly interactive training organization that have real life experiences in the field of agility I would highly recommend Red Tangerine for their courses.
