Modeling IT Systems: Techniques and Practice
Course Goal
Prepare participants for confident use of IT system modeling techniques, develop skills in diagram creation, technical solution communication, and mentoring in systems thinking.
The course is designed for:
- Mid-level developers interested in advancing to senior or tech lead roles
Learning format:
- Course duration: 18 hours + 2 hours for workshops (12 sessions × 1.5 hours)
- Online classes with an instructor
- Homework between sessions
- Final project: model a complete system
What participants will gain:
- Ability to choose appropriate modeling techniques for different scenarios
- Skills to create clear and communicative system diagrams
- Capability to use modeling to facilitate technical discussions
- Experience applying modeling in architecture reviews and design sessions
- Competency to mentor junior developers in systems thinking
Recommended tools:
- Free: draw.io, PlantUML, Mermaid
- Paid: Lucidchart, Miro, Figma
- Code-based: PlantUML, Mermaid, Structurizr
