I was not sure what to expect with this workshop.

With being in my role for about a year, I still am very unfamiliar with a lot of demand planning procedures and this was a good starting point, but also some of the statistical concepts were over my head. They will probably make more sense as I apply what I learned and re read the book

Towheed Chowdhury

I was really waiting to use the title CADP against my name. You will be happy to know that though I paid for the full training myself, my employer is reimbursing me the training cost after I shared the depth of knowledge I gathered from the training and certification program in Mumbai.
My employer will be more proud once I share my result with them tomorrow. Now, I can more proudly share about the benefits of the training as I am CADP certified now :)
If I am not mistaken, I am the first CADP from Bangladesh. Thank you once again to all behind the training organization and for your excellent training sessions in Mumbai


Instructors were very helpful and knowledgeable. Quick to provide more detail if a concept was unclear. Forecasting at Amway is more aligned with Strategic Planning and plays more of a consultation role rather than a supply chain role, so it was interesting to hear struggles of more supply chain focused forecasters


The overall structure of the workshop worked very well was a mix of theory with real world examples. I am new to demand role and this course is very helpful with learning the core concepts of demand planning
