We have worked with the Clean Code Developer initiative has compiled 45 principles and practices. Because no one can deal with 45 building blocks at once, we have divided them into 5 so-called grades. The grades are named with colors, like in the rainbow: red, orange, yellow, green and blue. There are between 8 and 10 principles and practices in each grade.
A long time ago, we produced postcards to help introduce the building blocks. These were long out of print, but .... Now they are available again! In our store at https://shop.ccd-akademie.de you will find them.
To the Download A new wallpaper is also available. It contains an overview of all five degrees based on the postcards.
