CS60171 Interactive System Design Mark van Harmelen

What’s design?
Design is a process where we
Start with multiple, often conflicting, requirements and constraints
Make tradeoffs
Produce ‘something’ at the end of the process

What’s interactive system design?
A process where we
Start with multiple, often conflicting, requirements and constraints user requirements system capabilities
Make tradeoffs usability and engineering tradeoffs
Produce ‘something’ at the end of the process a design for / a prototype of an interactive system

Tradeoffs in interactive system design functionality user interface scope

How not to do it
Big fat requirements documents ‘never mind the quality or usability, feel the weight!’ Leads to …..

How to do it: Mutual learning Goals, roles, tasks, results, things to do work with Tech stuff: code, datbases, internet, standards, …. Designers’ world Users’ world

What the users add
Front end design factors, roles, tasks, etc
Validation of our developing design for
Scope
Functionality
User interface
Before we write a single line of code
Less code change, less refactoring

How to do it: Rapidly at low cost

How to do it: The cycle Design Test Redesign / improve

Learn
Background theory
Practical time-efficient design methods
People skills, how to work in groups how to work in industry (the most important bit?)

The method
The Bridge-UML
A multistage process
We involve users and designers in a 3 to 5 day workshop and produce a validated interactive system design before writing any code

test and improve

Hey, we are developers, we like a nice design process (won’t the users mess it up?) requirements / specification process

Producing UML from the Bridge Use case Model (Use case Diagrams) Dynamic model (Activity Diagrams, …) Logical model (Class Diagrams)

A well-founded method

Past course: Computer prototype

Led to……

This year…..
Web app design
Mobile app design

Scope for
Very technical students
Human-interested students

Finally…..
Experiential learning = learning by doing
Authentic learning = real project experience
Fun !
‘ Best course I have ever attended’
‘ All courses should be like this’
