I was recently able to attend the App in a Day training at the Hitachi Customer Conference. This was a great day of learning and I would definitely recommend it to others.
The course walks through everything you need to know in order to build a Canvas App, a Model Driven App with a Business Process Flow, a Flow with Approval and a Power BI Dashboard.
It was great to be able to play with all of these features and the experience was greatly improved by having access to in-person experts available to help you through the process.
I wanted to share a few screenshots of the things I built to encourage you to take the class yourself. You can see all the classes available in your area here.
Note that it did take me a bit longer than the allotted class time to finish some of these items. The step-by-step instructions are yours to take home so you can finish at your own pace. The instructions also did not tell me how to turn everything PINK!
Fine print: All screenshots are my own but are based on the step-by-step instructions from Microsoft and provided to me by Hitachi Solutions.
