UML Guidelines
Unified Modeling Language (UML) is used as part of the design phase of all our projects. While it has become (arguably erroneously) popular since about 2010-2015+ to regress back to code-first, design-later, this invariably leads to unscalable and unsustainable projects. The code-first approach tends to lead to 10% new features code (forward progression of the code base features and scaling), 85% debugging/fixing (trying to maintain/fix the existing code base), <5% documentation = garbage code that can't be scaled, or maintained when constantly changing developer eyeballs/brains. The design-first approach, if correctly implemented with Object Oriented principles typically leads to 10-20% documentation, 20-50% new features coding iteration (forward progression of the code base), 20-40% debugging/iteration (trying to maintain/fix the existing code base), and is much easier to collaborate, maintain, and support over many years and many different eyeballs and brains.

We follow the principles of Object Oriented Design (OOD), even when not using OO languages, and design-first approach means it takes longer before we actually write working code (in the early phases), but leads to a much more sustainable, scalable, distributable, flexible, and manageable product overall.
