Software Architecture

Workflows in Software Architecture

• Purpose and Requirement Analysis: Define what problem the architecture must solve and who will use the system. ^[v70hr6]
• Component Identification: List all major system components (services, databases, APIs, UI, etc.) for Component-Based Software Architecture. ^{[3v2ip9] [8agett]}
• Interaction Mapping: Detail how components interact and exchange data. ^{[8agett] [v70hr6]}
• Diagram Creation: Develop high-level, system, application, and detailed diagrams using models like C4 (System Context, Container, Component, Code views). See Visual Software Development ^{[1szeqn] [3v2ip9] [v70hr6]} and Diagrams as Code

• Stakeholder Feedback and Review: Iteratively refine architecture via feedback from stakeholders and technical teams. ^[v70hr6]
• Documentation: Create and maintain architecture documentation—description of major elements, responsibilities, relationships, and constraints. ^[1szeqn]
• Architecture Patterns Selection: Apply suitable patterns (client-server, microservices, service-oriented). ^[z2rll0]

• Software Architecture Diagrams: Visual maps such as high-level, system, and application diagrams. ^{[3v2ip9] [8agett] [v70hr6]}
• Written Documentation: Structured specs outlining the architecture’s components, roles, and interactions. ^[1szeqn]
• Guidelines and Standards: Rules for system implementation, integration, and future scalability.
• Actionable Roadmaps: Step-by-step plans for development corresponding to the architecture.

Who is Involved?

• Software Architects: Lead architecture design and decisions.
• Developers: Help define feasible solutions, later implement the architecture.
• Business Analysts: Ensure alignment with business goals and requirements.
• Technical/Project Leads: Coordinate between teams, ensuring integration and consistency.
• Stakeholders (including managers): Validate that the architecture supports business needs. ^{[8agett] [v70hr6]}

Benefits of Investing in Software Architecture

• Improved System Reliability: Well-defined architecture reduces bugs and potential failures. ^{[3v2ip9] [8agett]}
• Scalability and Maintainability: A robust architecture is easier to upgrade and maintain. ^{[3v2ip9] [z2rll0]}
• Stakeholder Alignment: Quality documentation and diagrams foster clear communication, reducing misinterpretation by technical and non-technical teams. ^{[8agett] [1szeqn]}
• Reduced Technical Debt: Proactive architecture planning diminishes the likelihood of costly rewrites. ^[8agett]
• Efficient Team Collaboration: Clear diagrams and guidelines help onboard new members and synchronize existing teams. ^{[3v2ip9] [8agett]}

Risks of Neglecting Software Architecture

• Increased Technical Debt: Poor foundation leading to future refactoring and increased costs. ^[8agett]
• Miscommunication: Lack of clear diagrams/documentation causes misunderstandings among teams and stakeholders. ^{[8agett] [v70hr6]}
• Integration and Performance Issues: Systems may not scale as intended or may fail under load. ^[z2rll0]
• Reduced Agility: Inflexible design makes adaptation to new business requirements slow and error-prone. ^[3v2ip9]
• System Failures: Hidden assumptions and “spaghetti code” can trigger outages and security weaknesses.
