SOLID Development Principles – In Motivational Pictures
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
SOLID
Software development is not a Jenga game.
(This one was created by Mark Nijhof’s. He posted it via twitter and I’m borrowing it for my own collection.)
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?

There’s been a lot of request to re-use these images, so I’m going to release them under a Creative Commons license.
