Jammie and Sterling were both very engaging and provided great insight on how to create and graph the strongest insight possible. I have grown so much from the beginning of my first delta class. I feel much more comfortable with interpreting data and forming that into a strong insight and the correct graph. Thank you for a great class!

Jammie is a phenomenal principal and helped make the math and excel something that I understand ( which are NOT my favorite things to do). She helped me see how clearly defining my the business insights I needed to gain and how to follow a process to deliver executive level summaries and be impactful enough to generate conversation off of 1-2 slides. THIS IS A MUST DO CLASS for any business professional!

The teachers of the Delta classes are very good at understanding what most people struggle with and the “quick fix” for said issue. They are very understanding of work schedules as well and understand that life gets in the way sometime. As long as you put in the work and effort this class is very informational and has made my job as an analyst easier already.

Prior to taking this course, I believed my analytical skills were fairly strong. Little did I know, my ability to analyze data and communicate the true meaning of the facts needed A LOT of work. We all are living in a faster and more chaotic business environment than in years past. As a result, we need the skills to quickly get to the root of a problem and engage our customers in meaningful insights to cause action. This is what you will take away from completing this course.

Delta will help you BE BRIEF, BE BRILLIANT, BE GONE and your Customers will see the difference!

January 25, 2024

I recently had the opportunity to undergo the Delta Business Insights Training, and I must say it was a truly transformative experience. This comprehensive program not only lived up to its promises but exceeded my expectations in delivering valuable insights and honing essential business skills.

The curriculum is intelligently crafted, covering a wide spectrum of topics ranging from data analytics and market trends to strategic decision-making and leadership principles. The trainer (Jammie ♡) demonstrated a deep understanding of the subject matter and was adept at translating complex concepts into digestible, real-world applications.

One of the standout features of the Delta training was its hands-on approach. The program seamlessly integrated theoretical knowledge with practical exercises and case studies, allowing participants to immediately apply what they learned. This interactive methodology not only reinforced key concepts but also fostered a collaborative learning environment among participants.

I had a very difficult time sitting through each 8-hour sessions. Specifically, when the skills being taught did not translate to my work. I would become very frustrated knowing I would have responsibilities related to my current position that I would have to take care of due to the Delta class on that day. Overall I honestly would not recommend this class to anyone considering taking and paying for themselves.

Overall, the concepts learned, and the knowledge gained in this class are things that I will use throughout my career. I was unsure when the class started at what skill level I needed to be at to get utilize the learning and they made all of the concepts very easy to pick up on. Our instructor was always professional and even though the class was all online, it had a feel of being in the same room. The best thing about the class is that you are able to then turn around and immediately use the learning day to day. I would definitely recommend this class.

It didn’t take long for me to realize there was a lot more to learn from Jammie in the Black Belt Certification course. Jammie made sure our 8-hour classroom sessions were engaging, fun, and interactive, while explaining everything in a thoughtful way. Looking back at my presentation slides prior to completing this course to where I am now, it’s like a completely different person is doing the analysis. I highly recommend any analyst (or person that works with data) looking to sharpen their skills to take this course.

I went into the Delta Black Belt Level 1 class not knowing what to expect and feeling quite nervous for what was to come. These worried feelings quickly subsided as Jammie began instructing our class with a calm and fun approach to learning. Jammie made sure to explain and teach thoroughly, as well as pause frequently to ask students if there were any questions. Jammie also pushed students to recall specific items they learned, liked, want to get better at, etc. in order to create conversation amongst the class. I am very thankful to have gotten the opportunity to complete the Black Belt course and have had Jammie as an instructor. I am happy to conclude that although the course felt stressful at points, I learned an abundance of knowledge, tips, and tricks, completing the course with a smile! Thank you, Jammie!

Day one of Delta training was daunting due to the fact I was walking into class with little to no analytical back bone. As time progressed towards the final exam, I was beginning to identify similarities towards class work and real world work to help hone in and make comparisons that made sense in my mind. Finding the “golden nuggets” in a mess of data, writing a short, brief insight, and creating eye-friendly charts to back the insight up with visuals is now much easier and much more straight forward.

The instructors that enlightened my Delta journey (Sterling and Jammie) over the last 6 months were patient, detail-oriented, and very engaging during a virtual class setting. Given this course was 100% virtual is difficult I am sure to train and keep the class engaged, and both Sterling and Jammie did a fantastic job staying on us as a collective class while also being willing and able to offer constructive criticism when asked.

I feel confident as ever to continue my journey in my professional career development utilizing Delta along the way to set myself apart with the tools and resources learned in Black Belt Level 1.

Due to Covid I took this class virtually and still felt like the instructors (David and Jammie) were very good at getting to know me and engaging everyone. The class size is small so you can all interact with one another as well as the instructors. I felt comfortable asking questions or if I needed further explanations for anything. Examples were ‘real world’ which I believe is very beneficial. I began utilizing information as soon as we learned it!

Thank you for the great course…I’m getting compliments from vendors on the feedback I’m able to provide them.

The only downside, which is out of Delta’s control, is the teaching mode- of course, having the class in person would be better; however, the shift to breakout rooms, I think, was preferable. Thanks again to the team, and I look forward to utilizing more of the applications taught!

My Blackbelt Delta class was a great experience. I am excited to apply my new learnings into my everyday work. I wish this class was available to me a few years ago. It would have alleviated tons of stress and confusion in my prior roles. The new website was very helpful when it came to the homework/practice and I really enjoyed the Zoom format. I would recommend this class to anyone who wants to take their analytical skills to the next level.

Best story tellers always have numbers to back them up and to create a powerful story out of numbers is not easy as it may seem. Steve from Delta team taught us how to crunch the data together, identify key nuggets from the data and then present it in an impactful way.

Thank you Delta team for the support and guidance throughout the course.

Not only for sales people but also marketing, SC, Fin people, business skills for writing business insight and developing proposal story based on data are critical.

If you take the black belt level 1 course of Delta associates, you would acquire the formalized method to develop them in a concise manner.

Amazing course. Amazing trainers. I’ve never taken a course where I gained so much value that I can use as an Account Manager, or take with me to a future sales or marketing role. My knowledge of business insights has grown exponentially, thus my value. The trainers were very engaging and knowledgeable. Speed of the course was just right. I think virtual is the way to go! Thank you.

A pesar de que la modalidad fue en linea, y el periodo de tiempo enfrente de la laptop fue extenso, Jammie siempre se enfoco en tener la atención del grupo y en retarnos para mantenernos enfocados, el contenido del curso y la metodologia me parecieron super prácticas y útiles! estoy muy contenta de haberlo tomado. Muchas gracias por todo!

Delta Black Belt course review

I found the Delta Black Belt course to be one of the most useful business training courses that I have taken in over 10 years. I learned many extremely useful PowerPoint and Excel techniques that will help me to be more efficient, concise and impactful in explaining data going forward. I also learned the importance of simplifying my charts, to get across the main insight verses all insights. Something I have had trouble with in the past.

I found the course instructors to be fantastic, very knowledgeable about the content, able to encourage and instruct all levels of ability at the same time, and very friendly. They made the course enjoyable. The structure of 3 live classes separated by a few weeks packed with homework, helped to create muscle memory for all of the new techniques, so that what was learned in class will not be quickly forgotten.

I completed the Business Insights Black Belt Level1 course and found it to be very challenging, enlightening and helpful. The course and our awesome instructor Jammie Kokesh, taught us how to find, calculate and analyze the golden nuggets of retail sales data. With this information, we are now able to effectively identify and communicate the key business insights to our retail buyers.
