Teaming

Role of Teaming

• Major area for individual assessment
• Critical to design success
• General area of weakness

5
Timing

• Doing 1st major assignment
• Two major assignments coming up
• Stress strains

6
Opportunity

• Reflect
• Address

Importance of Addressing Teaming

• Team time
• 10 teaming
• 90 designing
• Team failure
• 90 teaming
• 10 designing

Principles Addressing Teaming

• Review the areas
• Avoid blame
• Favor praise
• Be helpful and productive
• Consider your role and responsibility
• Put it on the agenda!

Conceptual Design
20
The Phases

• Requirements
• What is Needed
• Conceptual Design
• What will Work
• Implementation
• Making it Work

21
The Methods

• Requirements
• Activity Analysis
• Conceptual Design
• Object Modelling
• Implementation
• Prototyping

22
The Deliverables

• Requirements
• Transformed Narrative
• Conceptual Design
• Model of the HCI
• Implementation
• Prototype of the HCI

23
The System
Transformed Narrative
24
Benefits to the HCI

• built upon analysis of cultural practices
• built upon an underlying conceptual model
• more than haphazard prototype

25
Intro to OVID
26
OVID Methodology

• OVID
• Object
• View
• Interaction Design

27
OVID Defined

• the underlying objects in an HCI
• seen through the Views of the user
• In their Interactions among one another
• Represented in an abstract Diagram

28
OVID Origins

• 1998
• Designing for the User with OVID
• Extending OOM to HCI

29
OOM Origins

• 1997
• Object-Oriented Modeling and Design
• GE / Rational

31
Problem of Multidisciplinarity

• Multiple Disciplines
• Programmer
• Graphics designer
• Usability
• HCI designer
• Each with their own methods

32
Problem of Abstraction

• User Interface 10
• User Interactions 30
• User Objects Interactions 60
• ERGO
• Need to support design work at the level of
  users objects their interactions

33
How OVID Works

• An abstract model of
• The objects the user interacts with
• The ways they interact
• The views through which the user works
• A model that is multidisciplinary

34
Objects in OVID Things
35
Views in OVID Actions
36
Interactions in OVID Operations
37
Key to Success Using OVID

• Model the User Objects
• Built on Your Transformed Narrative
• Model the User Actions
• Not just the interface but the users interaction
  with the interface
• Dont model the system
• cookbook, not the database

38
Conceptual Design Schedule

• Week 4 Lec 7-8
• Week 7 Lec 11/12
• Week 8 Modelling homework
• Lec 13/14
• Week 9 Spring Break
• Week 10 Lec 15/16
• Week 11 Presentations

39
Conceptual Design Deliverables

• model of the activity transformed by the HCI
