The lecture content was very helpful to me, so I am leaving a detailed review in case it will be of some help to those who are considering taking the course :) [Background for taking the course] - I work at a digital marketing agency to help accurately measure and improve advertising performance by better utilizing Ad Tech and data. - However, since the team was newly formed and we were working without a mentor, the process for solving problems based on data was not well established, so I took the course to stabilize the team's work system. [How I took the course] - I thought it would be virtually impossible to complete the course with just my own will, so I gathered study members on Discord...! (There were more people like me than I thought, lol) - I recruited people with similar goals and wills and opened a study group, and operated it for the purposes of 1) completing the course, and 2) sharing each other's experiences. - There were often cases where the content I needed right away was covered in the course while I was working, so I put the course up and used it as a handbook while working. - I organized the newly learned information or the information I wanted to share with my team members into a document in Jira Confluence and shared it, and spread the knowledge within the team. [What improved after listening to the lecture] - Other existing data-related lectures seemed to deal with technical aspects, but rather than these technical aspects, I was able to build the soft skills that are most needed in the field. - Communication became clearer as I gave names to frameworks and methodologies that I had been practicing without even knowing the names. - In particular, the problem definition framework and data log design part were the parts that were closest to my domain, so I received a lot of help in this area. - As I learned about various methodologies that I had not known before, I was able to approach and solve problems in new ways. [Who would you recommend it to] - I think it would be more helpful to current employees than job seekers (there are so many moments where you really agree and sympathize while watching the lecture...) - I think it would also be of great help to marketers who communicate based on data (you can gain insight into how to utilize trackers such as GA or Appsflyer) - I also recommend it to everyone who wants to solve problems based on data. Fighting to you all!
