Really tangible and useful. I have been able to take what I've learned in this specialization so far to create dashboards at work. I'm really pleased with how much I've learned in such a short time!
Week 1 starts off where Course 1 & 2 left off... more lectures without course-directed opportunity to apply the lessons. Week 1 is lead by guest Instructor Hunter (who led some of the weeks in earlier courses). He's an expert academic in his field, but without more practical application of principles, limited benefit.
Week 2 offers some hands on Tableau practice, which is great. The Data Quality lecture is a waste and can be skipped, as the instructor just rambles for 18 minutes, and doesn't share any insights that weren't covered in an earlier course. In summary... make sure the data is clean or clean it up (before bringing it into Tableau). I thought there'd be some Tableau tips and tricks, but there aren't... (with the exception of maps/locations).
Week 3, probably one of the best weekly sessions so far (for those really looking to dig in to Tableau). The Instructor goes through creating multiple worksheet visualizations, and creating a Dashboard, along with interactive filtering (that has barely been touched on till now). The most hands on / application to date IMO. The quiz asks questions not covered in this weeks lecture (covered in Week 4). I felt like I wasn't quite ready to create the Dashboard (the assignment), especially after going through Week 4, where they go in more depth about Story-boarding. If you're ahead of the game, skip the assignment in Week 3 till you go through Week 4 (much more context and examples to leverage).
Week 4, starts out with Hunter sharing too much academia without practical application (as seen in most of my critiques, I find little value in this, but personal preference). When it switches back to the primary instructor, things improve greatly. Skip the last lecture... he spends 20 minutes telling you how to take a screen-capture and paste it into PowerPoint...? The assignment takes what was learned from week 3, and building a story-board, which is great. I mentioned in week 3 that I struggled with the assignment, as they're essentially asking you to cram a story into one dashboard, so week 4 I unpacked my too-crammed dashboard into different slides (story-points).
