A '''design pattern''', also know as a software design pattern, is a reusable solution to a software engineering problem. Design patterns give the developer a starting point and can help improve efficiency, readability, scalability, and maintainability. Using a design pattern can help you easily expand your application and reuse your own development efforts when you want to add new features. Once you create a good architecture for your company, you can create templates that you and others can reuse for future projects.

Described below some useful design patterns that a developer can use in their application architecture. By no means is this a comprehensive list, and no one architecture should be considered as the "best", however it may be helpful to start with one of these design patterns, or variations on them. A good architecture is one that fits best for the application and can be a combination of the design patterns below.<ref>"Scalable Design Patterns in LabVIEW" by David Ladolcetta (https://forums.ni.com/t5/Developer-Center-Resources/Scalable-Design-Patterns-in-LabVIEW/ta-p/3534309)</ref>

Open source software projects are making huge contributions around the world. They allow communities to pool their resources and achieve progress that couldn’t be reached by individual teams in silos.

While there are open source projects in LabVIEW, it feels like a resource that we aren’t great at using as a community. Every project I’ve seen seems to handle things quite differently, and it can be hard to track down where to work.
