Systems Analysis Fundamentals: BPMN, ERD, and API Design

Transitioning business ideas into clear, structured technical requirements can be challenging without a systematic approach. This course teaches you how to analyze problems at a system level and break them down into precise, actionable technical components. You will transition from thinking about vague features to designing structured workflows, relational database models, and clear API specifications. By mastering industry-standard modeling frameworks, you will bridge the gap between business needs and technical implementation. What you'll learn: Analyze business processes and design clear workflows using BPMN diagrams; Create structured database schemas using Entity-Relationship Diagrams (ERD); Write precise API specifications that clearly define frontend and backend interactions; Document system architecture levels using the C4 model for microservices; Draft actionable technical requirements for both frontend and backend development teams; Apply modern system design patterns to ensure scalability and separation of concerns. The course starts with the foundational concepts of systems analysis and decomposition. You will then progress through structured modules covering business process modeling, database design, API documentation, and architectural mapping, reinforced by written practical scenarios. This course is designed for beginner systems analysts, business analysts looking to build technical skills, and developers wanting to improve their system design capabilities. No prior engineering experience is required. Start reading today to master the art of system-level task decomposition and technical design.
