This is the result of Aerospace and Defense projects becoming larger and more sophisticated. To solve this problem, the complexity that has been introduced has to be identified, reduced, and managed. This will lower the overall cost and keep projects on schedule.  As an example, Tesla puts a strong emphasis on modularity (reduced complexity) across all their hardware. So during the recent chip shortage, they were able to quickly switch to chips that were available and continue to make and sell cars with minimal disruptions. One technology that can be used to reduce complexity (and increase modularity) is the Dependency Structure Matrix (DSM). ![Sean Barow](https://blog.lattix.com/hs-fs/hubfs/WIN_20170321_13_30_11_Pro.jpg?width=45&name=WIN_20170321_13_30_11_Pro.jpg) [Sean Barow](https://blog.lattix.com/author/sean-barow) [Read More](https://blog.lattix.com/using-dsm-in-large-scale-aerospace-and-defense-manufacturing) ![](https://www.lattix.com/wp-content/uploads/2019/07/dsm_v2-e1564515209967.png) ### [What is Architectural Refactoring?](https://blog.lattix.com/what-is-architectural-refactoring) Mar 1, 2022 7:22:55 PM - [View Larger Image](https://www.lattix.com/wp-content/uploads/2019/07/dsm_v2-e1564515209967.png) ![Sean Barow](https://blog.lattix.com/hs-fs/hubfs/WIN_20170321_13_30_11_Pro.jpg?width=45&name=WIN_20170321_13_30_11_Pro.jpg) [Sean Barow](https://blog.lattix.com/author/sean-barow) [Read More](https://blog.lattix.com/what-is-architectural-refactoring) ![](https://blog.lattix.com/hubfs/Imported%20sitepage%20images/ArchitecturalAnalysisPic.jpg) [Software Complexity](https://blog.lattix.com/tag/software-complexity) ### [Architecture Erosion in Agile Development](https://blog.lattix.com/architecture-erosion-in-agile-development) Feb 17, 2022 3:39:52 PM Software architecture erosion refers to the gap between the planned and actual architecture of a software system as observed in its implementation.1 ![Sean Barow](https://blog.lattix.com/hs-fs/hubfs/WIN_20170321_13_30_11_Pro.jpg?width=45&name=WIN_20170321_13_30_11_Pro.jpg) [Sean Barow](https://blog.lattix.com/author/sean-barow) [Read More](https://blog.lattix.com/architecture-erosion-in-agile-development) ![MOSA DSM](https://blog.lattix.com/hubfs/dsm_system_model_mosa_600_335.jpg) [Modularity,](https://blog.lattix.com/tag/modularity) [MOSA,](https://blog.lattix.com/tag/mosa) [DoD](https://blog.lattix.com/tag/dod) ### [Shifting MOSA (Modular Open Systems Approach) to the left](https://blog.lattix.com/shifting-mosa-modular-open-systems-approach-to-the-left) Feb 11, 2022 2:52:01 PM The weapons systems world is changing. The technology is improving rapidly, requirements for performance are increasing and weapons systems are often required to have 30-50 year service lifetimes. The DoD believes an open systems approach can help. An open system approach considers how a system will be supported throughout its lifecycle at the beginning of the project by using commercially available, widely used interface standards and a modular design approach to combine commercial products from multiple vendors to create a complete weapons system. For the DoD, the recommended method for implementing open systems is [MOSA (Modular Open Systems Approach).](https://www.dsp.dla.mil/Programs/MOSA/)  ![Sean Barow](https://blog.lattix.com/hs-fs/hubfs/WIN_20170321_13_30_11_Pro.jpg?width=45&name=WIN_20170321_13_30_11_Pro.jpg) [Sean Barow](https://blog.lattix.com/author/sean-barow) [Read More](https://blog.lattix.com/shifting-mosa-modular-open-systems-approach-to-the-left) ![Lattix DSM](https://blog.lattix.com/hubfs/Lattix_codebase_DSM.png) [Security,](https://blog.lattix.com/tag/security) [Log4j,](https://blog.lattix.com/tag/log4j) [Lattix Architect](https://blog.lattix.com/tag/lattix-architect) ### [How Lattix handled the Log4j security vulnerability](https://blog.lattix.com/how-lattix-handled-the-log4j-security-vulnerability) Dec 27, 2021 3:52:46 PM "The log4j vulnerability is the most serious vulnerability I have seen in my decades-long career", [Jen Easterly](https://www.cnbc.com/video/2021/12/16/log4j-vulnerability-the-most-serious-ive-seen-in-my-decades-long-career-says-cisa-director.html) US Cybersecurity and Infrastructure Security Agency Director  ![Sean Barow](https://blog.lattix.com/hs-fs/hubfs/WIN_20170321_13_30_11_Pro.jpg?width=45&name=WIN_20170321_13_30_11_Pro.jpg) [Sean Barow](https://blog.lattix.com/author/sean-barow) [Read More](https://blog.lattix.com/how-lattix-handled-the-log4j-security-vulnerability) ![Lattix AutoSAR](https://blog.lattix.com/hubfs/autosar_architecture.png) [AutoSAR,](https://blog.lattix.com/tag/autosar) [Automotive,](https://blog.lattix.com/tag/automotive) [Modularity](https://blog.lattix.com/tag/modularity) ### [Modularity in Automotive Software](https://blog.lattix.com/modularity-in-automotive-software) Dec 20, 2021 9:33:07 AM "Any customer can have a car painted any color that he wants so long as it is black" - Henry Ford ![Sean Barow](https://blog.lattix.com/hs-fs/hubfs/WIN_20170321_13_30_11_Pro.jpg?width=45&name=WIN_20170321_13_30_11_Pro.jpg) [Sean Barow](https://blog.lattix.com/author/sean-barow) [Read More](https://blog.lattix.com/modularity-in-automotive-software) [1](https://blog.lattix.com/author/sean-barow) [2](https://blog.lattix.com/author/sean-barow/page/2) #### PRODUCTS - [LATTIX 2021](https://www.lattix.com) - [LATTIX ARCHITECT](https://www.lattix.com/products/#architect) - [LATTIX SUITE](https://www.lattix.com/products/#_lattix_suite) - [CI/DEVOPS](https://www.lattix.com/products/#devops) - [SUPPORTED TECHNOLOGIES](https://www.lattix.com/supported-technologies/) #### SOLUTIONS - [OVERVIEW](https://www.lattix.com/solutions/#overview) - [ARCHITECTURE ANALYSIS](https://www.lattix.com/solutions/architecture-analysis) - [CI DEVOPS](https://www.lattix.com/solutions/ci-devops) - [ARCHITECTURAL REFACTORING](https://www.lattix.com/solutions/architectural-refactoring) - [IMPROVE BUILD](https://www.lattix.com/solutions/improve-build) - [IMPROVE TESTING](https://www.lattix.com/solutions/improve-testing) - [COMPLIANCE](https://www.lattix.com/solutions/functional-safety-compliance) - [SYSTEMS ENGINEERING](https://www.lattix.com/solutions/systems-engineering) #### SERVICES - [OVERVIEW](https://www.lattix.com/services/overview) - [ARCHITECTURAL CONSULTING](https://www.lattix.com/services/architecture-consulting) - [REFACTORING CONSULTING](https://www.lattix.com/refactoring-consulting) - [FUNCTIONAL SAFETY CONSULTING](https://www.lattix.com/services/functional-safety-consulting) - [CI DEVOPS SERVICES](https://www.lattix.com/services/ci-devops-services) - [SYSTEMS ENGINEERING SERVICES](https://www.lattix.com/services/systems-engineering-services) #### RESOURCES - [CASE STUDIES](https://www.lattix.com/resources/#casestudies) - [WHITEPAPERS](https://www.lattix.com/resources/#whitepapers) - [VIDEOS](https://www.lattix.com/resources/#videos) - [BLOG](https://www.lattix.com/enterprise-architecture-blog) #### About - [MANAGEMENT](https://www.lattix.com/architecture-solutions-about/#management) - [FAQ](https://www.lattix.com/architecture-solutions-about/#faq) - [CONTACT US](https://www.lattix.com/architecture-solutions-about/#contact) - [EVENTS](https://www.lattix.com/architecture-solutions-about/events) - [PARTNERS](https://www.lattix.com/partners) - [PRIVACY POLICY](https://www.lattix.com/architecture-solutions-about/privacy-policy) Follow us on Facebook Follow us on LinkedIn Follow us on Twitter Follow us on Instagram
