I found the Motivator this morning. It lets you create your own motivational pictures. So, here’s my first run at creating the SOLID software development principles in motivational picture form. I ‘borrowed’ the images from google image search results. I hope you find them to be as fun as I do! I have them all hanging up in my team room, already. :)
(Update: I never expected the response to this post to be so great! There have been many inquiries about prints, high res versions, etc. As I said in the comments below, the source pictures that are linked via the thumbnails are all I have. There does appear to be some effort to produce high res versions, though. See the comments for more info!)
Update: Due to the continuous request for prints, posters, calendars, etc, we (LosTechies) are looking into what it would take to get these turned into high quality prints of various types. I don’t have any detail yet, but I am hoping to have some good info on this, fairly soon.
Update: Steve Smith and the NimblePros crew have created their own version of the posters, along with other principles, in a Calendar for 2011. Go get yours, here: http://nimblepros.com/products/software-craftsmanship-2011-calendar.aspx
Software development is not a Jenga game.
Single Responsibility Principle
Just because you can, doesn’t mean you should.
(Update: I knew I had seen this Swiss Army knife in a Single Responsibility post before. Gabriel reminded me where.)
Open Closed Principle
Open chest surgery is not needed when putting on a coat.
Liskov Substitution Principle
If it looks like a duck, quacks like a duck, but needs batteries – you probably have the wrong abstraction
Interface Segregation Principle
You want me to plug this in, where?
Dependency Inversion Principle
Would you solder a lamp directly to the electrical wiring in a wall?
