The discipline integrates system parts that, when combined, offer unique structural and behavioral characteristics that no single system could build on its own. These initiatives lack a solid foundation and sturdy structure to build on without good systems design. As a result, their development tends to be slow and error-prone. Robust software architectures combine existing components (both open source and proprietary) into functional bundles that can be easily installed or removed as needed. They are flexible enough to accommodate new requirements while at the same time being stable enough to not collapse under their own weight. Finally, they should be able to stand up to public scrutiny by allowing for easy modification of their inner workings by users who know what they're doing. These bundles must be well thought out and have a clear purpose. They should not include functionality that could be achieved in a more efficient way by using a single component. Similarly, it's important that each bundle uses only free and open source software where possible. This will help prevent future problems arising from incompatibilities between different types of programs. It also gives developers more freedom to modify and improve the underlying code if necessary. Finally, consider using modular programming techniques such as object orientation when building robust architectures. This will help you avoid complex interdependencies between bundles that may not be evident at first glance.
