# A pattern is at its simplest a statement of a problem with its solution.
Our goal is to foster an open-sourced global system of neighborhood problem solving knowledge that is vernacular, reusable, and adaptable.
We are storing this knowledge in a particular type of wiki--a federated wiki.
Our aim is to create a System of Patterns otherwise known as Pattern Languages.
Many of us are familiar with Vester's Sensitivity Model as described in his book, "The Art of Interconnected Thinking".
The Sensitivity Model is an example of a pattern language. Each tool can be shared as a pattern and they can be variously linked together (language syntax) in different situations. I prefer to think of it as a system of patterns of models.
At any rate: let's look at a pattern and then create one ourselves. Take a quick look at Causal Loop Model.
Here is a template for structuring and communicating patterns: Pattern Template.
.
* [ ] What key **problem** do you personally know a lot about solving in various places and situations? * * *
* [ ] Describe the **context** in which this problem commonly shows up. * * * * * *
* [ ] Describe the **problem**. * * * * * *
* [ ] Describe the **solution**. * * * * * *
**Useful sequences of patterns (sometimes referred to as pattern languages) can be constructed of linked patterns. Begin creating a sequence:**
* [ ] List at least one thing that **supports this solution**. * * *
* [ ] List at least one problem/solution that **this solution supports**. * * *
**Fully developed patterns are interesting and engaging by design. This includes brief explanations, illustrations and diagrams.**
* [ ] Can you think of **illustrations and diagrams** that could further illuminate the solution. * * * * * *

What can you imagine might come if it if you or others used this exercise elsewhere? * * * * * *
