Many different perspectives of design…

  • Product Vision
  • Sales / Business
  • Information Architecture
  • User Interface
  • Hardware
  • Development / Code Details
  • Software Architecture

What is Design?

  • Noun

– “The design”

  • Verb

– “To design”

  • Sensibility

– “Great design”

  • Methods

– Act of doing/creating the above

Design Thinking

  • 1. A way of thinking

about design.

  • 2. A collection of design

focused methods.

A WAY OF THINKING ABOUT DESIGN

14

slide-14
SLIDE 14

A set of modes that can be applied in any order.

A mindset.

15

slide-15
SLIDE 15

Design Modes Explore Evaluate Understand Make

16

slide-16
SLIDE 16

Understand Actively seek information from stakeholders and work to (re)frame the problem.

17

slide-17
SLIDE 17

Explore Use generative thinking to identify design concepts and engineering approaches.

18

slide-18
SLIDE 18

Make Realize design concepts by creating them in the real world as a model, prototype, program, or other artifact.

19

slide-19
SLIDE 19

Evaluate Determine the fitness of design decisions and decide whether to revisit other modes.

A COLLECTION OF DESIGN FOCUSED METHODS

22

slide-22
SLIDE 22

Method

An activity that embraces specific design modes and actively promotes learning.

23

slide-23
SLIDE 23

Architecture-Focused Design Methods

  • Understand: Quality attribute scenarios, personas, empathy map, system

properties web, architecture drivers specification, user journey, elevator pitch, user mad lib, …

  • Explore: System journey, design the extremes, define the design concept,

yours and mine list, round-robin, estimate the elements, system research, soap boxing, paths not taken, name the styles/patterns, …

  • Make: Create a template, mock-ups, paper prototype, functional prototype,

sketches/cartoons, architecturally evident coding style, system metaphor, architecture haiku, context diagram, utility tree, module decomposition, viewpoints and views, must reads list, …

  • Evaluate: Scenario walk-through, dot voting, I like/I wish/what if, feedback

capture grid, risk storming, bull’s eye, Question-Comment-Concern,…

Question – Comment – Concern

Evaluate

25

slide-25
SLIDE 25

26

slide-26
SLIDE 26

Question – Comment – Concern

Brainstorming technique that helps quickly identify and visualize specific areas in the system that may require further thought. Benefits:

  • Visualize risky or concerning parts of the system
  • Promote knowledge sharing
  • Identify areas in need of research or exploration

27

slide-27
SLIDE 27

Stakeholder Maps

Understand

28

slide-28
SLIDE 28
slide-29
SLIDE 29

Stakeholder Map

A network diagram of the people involved with or impacted by a given system or system design. Benefits:

  • Identify more than the usual stakeholders
  • Document, guide plans for research
  • Keep focus on people rather than technologies
slide-30
SLIDE 30

System Properties Web (or Quality Attributes Web)

Understand

31

slide-31
SLIDE 31
slide-32
SLIDE 32

System Properties Web

Help stakeholders to collaboratively generate, affinity cluster, and prioritize raw quality attribute scenarios Benefits:

  • Focus on system qualities over functions/feature
  • Visually show how systems differ by looking at

quality attributes

Agenda Tips

  • No surprises
  • Are the right people in the room?
  • Don’t forget breaks
  • Be prepared
  • Where can you be flexible?

44

Example: Ground Rules

  • No right or wrong answers
  • Watch the clock (I’ll help too)

–I’ll give you time limits –When it’s time, it’s time

  • Ask questions if you need help or clarification
  • Help each other
  • HAVE FUN! 
