Throughout the last five weeks, you have been introduced to some of the most important concepts and theories in supply chain management. I flushed down the supply chain diagnostic framework for you in five distinguishable categories of supply chain strategy, logistic strivers, network design, sourcing decisions, and risk and sustainability as a standard go-to framework you can use to conduct a diagnosis on any supply chain from higher level strategic planning to operational level supply network design and analysis. The supply chain diagnostic framework you've learned in this course can also be leveraged to design end-to-end supply chain operations and logistics for any given product or service. This week, we put this supply chain diagnostic framework to the test and apply to three different cases that either require diagnosis or need part of their supply chains operations designed. I'll introduce each case at the beginning of its video. I'll also discuss my approach to developing a solution for the problems illustrated in each case, but I strongly suggest that before watching the solutions, you try to figure it out yourself using your learnings so far. That way, you'll have a better understanding of your strengths and weaknesses in the role of supply chain manager or supply chain executive. You'll certainly be entitled to a bonus video after finishing these three cases. That's why in the last video for this week, I'll talk about the application of disruptive technologies in supply chains now and in the future. While some of you might have already embraced these technologies in some aspects of your business, for others, this topic might be an as-yet unexplored area that's definitely worth knowing about. I hope you enjoy both parts of this week's learnings and more importantly, I hope this course has picked your interest in supply chains or added to your existing knowledge of supply chains and global businesses.
