Design Modeling Workshop (UML)

Workshop Approach

Design Modeling Workshop

A practice-focused session where participants build UML design models on realistic exercises with feedback.

Learning by Doing

Design skill grows through repeated practice and review, which this workshop emphasizes over lecture.

Collaborative Design

Designing together so knowledge is shared and diverse perspectives strengthen the result.

Foundations

Object-Oriented Design

Deciding how a system is built as collaborating objects, refining analysis with implementation decisions.

Design Model

A model that adds architecture, interfaces, and detail to the analysis model so the system can be built.

From Analysis to Design

Transforming analysis classes and responsibilities into an implementable design.

Applying Principles

Cohesion and Coupling

Designing components that are internally cohesive and loosely coupled for maintainability.

SOLID Principles

Applying five OO design guidelines to produce robust, flexible designs.

Encapsulation

Hiding internal data behind interfaces so implementations can change safely.

Design for Change

Structuring the design so likely changes are localized and inexpensive.

Applying Patterns

Design Patterns

Applying proven, reusable solutions to recurring problems during the workshop exercises.

Choosing a Pattern

Selecting patterns by matching the problem's intent to a pattern's purpose and consequences.

Avoiding Over-Engineering

Using patterns where they add value rather than adding unnecessary complexity.

Diagrams

Design Class Diagram

A detailed class diagram with attributes, operations, visibility, and relationships ready for implementation.

Sequence Diagram

Specifies how objects collaborate over time to realize designed behavior.

Component Diagram

Shows components, interfaces, and dependencies for the design structure.

State Machine Diagram

Models states and transitions for objects with rich lifecycle behavior.

Package Diagram

Organizes design elements into packages to manage large models.

Refining

Design Review

Critiquing a design for cohesion, coupling, clarity, and whether it satisfies requirements.

Refactoring the Design

Improving the design's structure without changing its intended behavior.

Common Design Smells

Signs of poor design — large classes, tight coupling, duplication — that the workshop helps recognize and fix.

Just Enough Design

Designing enough to guide implementation and reduce risk without over-specifying.

Applying It

Traceability

Ensuring the design demonstrably supports the requirements and analysis it derives from.

Team Design Skills

Building shared design technique and vocabulary so teams collaborate effectively on design.
