Visualize Code with Software Architecture Diagrams
The source code is the design. This famous motto means that no matter how many diagrams you draw and discuss with your colleagues, what matters is how the existing source code is actually structured. The need for visualizing code It is important to distinguish between the static view of code (how classes depend on each other in …

Modularity Parable and Software
In his seminal book, The Sciences of the Artificial, Herb Simon describes the parable of watchmakers named Hora and Tempus. They built watches out of 1000 parts. The watches were of the highest quality – as a result, they were often interrupted by customers calling up to place orders. However, they built watches using different techniques. Tempus …
DevOps and Testing Software Architecture
Forbes Magazine famously wrote that “Every Company is a Software Company.” Your company must become more responsive and agile using software and technology. And if the software doesn’t work or gives customers a bad experience, it can lead to lost revenue. This has led to the DevOps phenomenon, which is speeding up deployment of software …
Four Reasons to Refactor your Code
1. Maintenance is easier Legacy code architecture erodes over time and becomes difficult to maintain. Legacy code bugs are harder to find and fix. Testing any changes in legacy code takes longer. Even small changes can inadvertently break the application because over time the design has been extended to accommodate new features and the code …
Motivation for Software Architecture Refactoring
Refactoring is commonly applied to code, but refactoring can also be applied to other development artifacts like databases, UML models, and software architecture. Refactoring software architecture is particularly relevant because during development the architecture is constantly changing (sometimes for the worse; see our blog post on Architectural Erosion) and expanding. Software architecture refactoring should happen regularly …
