| From Silver to Gold:
Integrated Environments to Support Working, Thinking, and Learning |
| Gloria Gery, Gery
Associates |
| |
 We have ubiquitous technology,
widespread networks, and rich media. We have eLearning and portals and
usable software and collaboration tools. We have almost universal
experience with computers: the average worker probably uses between five
and ten software applications. But we're still frustrated about
technology. What is missing? What must is needed for people trying to do
meaningful work, to learn quickly, and to connect with others? Elegant
technology threads, content, and software have been thrust upon users
who must then put them together. Integration is what is missing, and we
must achieve it in our design of integrated work environments. In this
conference keynote, Gloria Gery will talk about and illustrate what is
necessary to have us shift from weavers of silver threads to achieving
integrated, golden woven environments that help people successfully
learn, do, and collaborate in carefully designed spaces. |

| M11 - 11:00a-12:30p |
| Performance Support for
Complex Problem-Solving Tasks |
| Chet Leighton, Infomark
Software Corporation; Cindy McCabe, CGM Communications |
| |
A case study is presented of
Just-In-Time (JIT) learning in an Electronic Performance Support System
(EPSS) for use by instructional designers in the Department of
Instructional Technology at San Francisco State University performing a
moderately-structured problem-solving task. The design of this EPSS is
based on the concepts of learning-by-doing and the advanced teaching
methods of the Cognitive Apprenticeship framework. A demonstration of
the software will emphasize how these teaching methods--modeling,
coaching, scaffolding, articulation, reflection, and exploration--are
supported. Data on how people actually used this EPSS will be presented,
including results of a formative evaluation of the software. Planned
future enhancements will be discussed. |
|
| M12 - 11:00a-12:30p |
| Designing a Useful and Usable
Web Site: Applying Scenarios and Profiling Techniques |
| John Sandler, IBM GSA
(Australia) |
| |
For a web site to be successful it
needs to be designed to incorporate customer requirements into the
interface. Whatever the function of the site, if it doesn’t give
customers a successful user experience they will leave. Activities that
find out what users want and value are critical not only for e-commerce
sites, but also for sites that deliver training, educational content,
performance support and workplace-related knowledge. This session will
cover a five step process for making Web sites more useful and usable.
These steps include clarifying the purpose, profiling users,
prioritizing user tasks and requirements, describing usage scenarios,
and low-fidelity prototyping. Based upon the results from these steps,
iterations of the site structure are created and further evaluated over
a short period of time to assist in refining design decisions. |
|
| M13 - 11:00a-12:30p |
| Usage-Centered Exploration -
Jump-Starting the UCD Process |
| Helmut Windl , Siemens AG
(Germany) |
| |
This session introduces a structured
approach to the early stages of usage-centered design. When designers
start a project, they often face questions of how to proceed. What
information is needed? Where and how can one get this information? What
questions should be asked? Which users should be asked? What is the
appropriate level of detail for models? Usage-Centered Exploration (UCE)
is an efficient, structured method to reduce the time and costs of user
and task analysis in usage-centered design. Starting with exploratory
user role and task models built from existing information, the process
refines them into final form through structured interviews, field
studies, and investigation of the user’s workflows and processes. The
session will cover the use of existing information, including what types
of information are necessary and most useful. It will discuss the use of
marketing information and research and how to handle requirements from
sales and marketing people. It will show how to build exploratory user
role and task models as well as how to build and evaluate final models
collaboratively with users. |
|
| M21 - 2:00p-3:30p |
| Performance Centered Systems:
What They Are and Why They Work |
| Gloria Gery, Gery
Associates |
| |
There are things that are very
different about systems that directly support work performance from
those that are simply "usable" by experts. In this workshop, Gloria Gery
will describe, discuss and illustrate software that is specifically
designed to enable people who don't know what they are doing to do it as
if they did -- while still accommodating expert performers. These
software applications integrate task structuring support, knowledge,
data, tools and collaboration methods -- and automatically produces
required deliverables. Gloria will provide an overview of the
characteristics and behavior of performance centered systems that will
clearly differentiate them from the often data-centric software being
designed today. |
|
| M22 - 2:00p-3:30p |
| From Essential Use Cases to
Objects |
| James Noble, Victoria
University, Wellington (New Zealand) |
| |
How can one turn a good usage-centered
design into robust and well-engineered software? Employing essential use
cases in typical object-oriented development processes requires
designers to translate them into conventional, concrete form, costing
time, imposing rework, and delaying software development until the user
interface design is completed. This session shows how essential use
cases can be employed in a responsibility-driven design process to guide
object-oriented development directly. This approach not only speeds and
simplifies software development, but improves tracking of requirements
and helps reveal recurring patterns in use cases. The process will be
illustrated with examples. |
|
| M23 - 2:00p-3:30p |
| Panel: Putting Usage-Centered
Design to Work |
| John Cady, University of
Michigan; Molly Corbett, Terra Lycos; Judy Dean, University of Michigan; Jeannine Strope, McKesson;
moderated by Lucy Lockwood, Constantine & Lockwood |
| |
This panel explores the perils, pains,
and payoffs of usage-centered design in practice. It draws on the
experiences of people who have been applying usage-centered design in a
variety of settings to a range of problems. |
|
| M31 - 4:00p-5:30p |
| Supporting User Intent:
Information Portal Design Based on Customer Data |
| Karen Holztblatt,
inContext |
| |
When customers come to your website,
they want information and help streamlining daily tasks. Are they
getting what they need? This talk presents key findings and
recommendations that have emerged from our work with information sites
in the high-tech and health industries. Our field interviews combined
with an analysis of websites suggest key principles for site design.
Information portals that work are structured to directly support the
user’s intent. This talk will help you know how to design beyond
categories, draw more customers to your site, and increase your brand
value through the structure of your site. |
|
| M32 - 4:00p-5:30p |
| Lessons Learned Using
Modeling Techniques for Usage-Centered Design |
| Alyce Neperud, Artemis
Alliance |
| |
This session addresses best practices
for the use of models based on lessons learned from real project
experience. It provides an overview of the primary models and artifacts
in a software development process using usage-centered design techniques
and the standard object modeling language (UML). Specific examples will
demonstrate how models can be an effective part of a project strategy
for interactions with customers and for communication, collaboration,
and decision-making within the development team. It will show the
benefits of choosing models early but making adjustments to keep on
track with project goals, how to complement use cases with other views
to successfully gather and communicate system requirements and design,
and how to combine or adapt models to best convey information in a
coherent way. The session offers a practical understanding of how to use
models in an effective and adaptive way to meet your project goals. |
|
| M33 - 4:00p-5:30p |
| Usage-Centered Design and the
Rational Unified Process |
| Christopher Armstrong and
Bobbi Underbakke, ATC Enterprises |
| |
Usage-centered design (U-CD) is an
established process for building models that represent how a user
interface should be designed to support the usage needs of a system’s
users. The Rational Unified Process (RUP), a collection of industry best
practices, is encyclopedic except in terms of user interfaces--on which
it is limited--and usage-centered design--on which it offers nothing.
Despite some omissions and shortcomings, the RUP has numerous benefits,
including standardization of terminology and an effective software
process meta-model. The RUP can be integrated with U-CD by using basic
extensions and very clear definitions. The Unified Modeling Language (UML),
which plays an important role in visualizing the models in the RUP, can
be extended to capture the three core U-CD models: the user role model,
the task model, and the content model. This presentation will discuss
the issues and provide real-world examples of how these two seemingly
disparate approaches can be used together very effectively.

Event - 6:00p-7:30p |
| DRINKS, DEMOS, and DISCOURSE |
| |
| |
Demonstrations include: "iSpace: A Web-Based Tool for
Abstract User Interface Prototyping" [Jeff Rogers]
Abstract user interface prototypes are a powerful technique for
improving the process of user interface design by allowing designers and reviewers to focus on the
essentials without becoming distracted by details. A Web-deployed tool for building and
reviewing abstract user interface models by interacting with a series of
Web pages will be demonstrated. |
|
TUESDAY |
| Panel - 9:00a-10:30a |
| Roles and Personas, Task
Cases and Scenarios: Does it Matter? |
| Larry Constantine,
Constantine & Lockwood; Kim Goodwin, Cooper Design; Karen Holtzblatt, inContext; Thyra Rauch, IBM; Mary Beth Rosson, Virginia
Tech; moderated by James Noble, Victoria University of Wellington (New
Zealand) |
| |
This panel will take a hard look at
the commonalities and differences among dominant design methods,
comparing and contrasting contextual design, Goal-Directed design,
usage-centered design, and scenario/story-driven approaches, especially
in terms of key concepts and techniques. What do the differences in
emphasis mean and do they matter? What are the strengths and weaknesses
of the various approaches. These and other questions will be addressed
by a distinguished panel of expert proponents. |
|
| T11 - 11:00a-12:30p |
| Lightweight Web-Based Tools
for Usage-Centered and Object-Oriented Design |
| James Noble, Victoria
University, Wellington (New Zealand) |
| |
A set of Web-deployed tools for
usage-centered design and object-oriented design will be presented.
These tools, in use in both consulting and education, support user role
modeling, use cases, and object-oriented design. The presentation will
cover how the tools are used, how and why they were built, and how
others can also develop custom tools to fit their design and development
processes. |
|
| T12 - 11:00a-12:30p |
| Designing an Award-Winning
IDE: Creating STEP 7 Lite with Usage-Centered Design |
| Helmut Windl, Siemens AG
(Germany) |
| |
This case study will offer a close and
revealing look behind the scenes in the design and development of an
award-winning commercial software product--a fully integrated
development environment (IDE) for programming the specialized computers
(programmable logic controllers or PLCs) that operate modern industrial
automation equipment. Guided by a time line, this presentation will step
through the whole design process to share the lessons learned in the
first large-scale effort at Siemens using usage-centered design (U-CD).
It will look at struggles with the project management, how the
management decision to use U-CD was upheld, the use of a consulting
team, on-the-fly redesign of the development process. The session will
report some surprising findings of interest to designers, including the
myth of killer features and what we found, why content modeling caused
problems and how we solved them, why and how we used high-fidelity
prototypes, what we learned from testing and what we did wrong in
design. |
|
| T13 - 11:00a-12:30p |
|
Performance-Centered Portals |
|
Gary Elsbernd and Matt Hummel, Ariel Performance
Centered Systems |
| |
Performance-centered portals provide access to
knowledge, data, task structure, job aids, and tools needed to support
the organizational goals. Performance-centered portals go beyond
navigation and centralization of information to directly promoting
organizational values and individual performance through focused and
customizable presentation of corporate resources available at a click.
Performance-centered design can be an attribute of commercial, learning,
or corporate portals, but few portals have taken the steps to design to
enhance individual performance. In this session, we will look at how
Performance-centered portals can be designed to enhance individual
employee performance and make a direct impact on an organization’s
bottom line. The session covers types of portals, individual and
organizational impact, and getting started. |

| T21 - 2:00p-3:30p |
|
Scenario-Based Design of Human-Computer Interaction |
|
Mary Beth Rosson, Virginia Tech |
| |
Scenario-based design elaborates a
traditional theme in human-computer interaction (HCI)--that human
characteristics and needs should be pivotal considerations in the design
of interactive systems. In scenario-based design, descriptions of usage
situations are more than orienting examples; they are first-class design
objects. This presentation introduces an iterative framework for
analyzing and transforming scenarios of work practice into new
activities. The scenarios depict actors, goals, supporting tools, and a
sequence of thoughts, actions, and events through which goals are
achieved, extended, obstructed, and/or abandoned. Scenario
transformation is inspired by metaphors and technology, constrained by
human-computer interaction guidelines, and refined through empirical
evaluation. |
|
| T22 - 2:00p-3:30p |
|
Web Design Patterns for High Volume Transactional Systems |
|
James Hobart, Classic System Solutions |
| |
This presentation will explore the creation and usage of visual design
patterns for solving complex design issues with web-based technology. We
will discuss how we have been documenting transactional design patterns
and will look at some specific examples of transactional design patterns
to see how they can be derived and refined with usage centered design
principles. |
|
| T23 - 2:00p-3:30p |

Beyond Code Freeze: Use Cases that Don't Leave QA
and Documentation in the Cold |
|
Rhonda Lynn, Sterling Commerce |
| |
Use cases have received wide attention for their
use in design, but use cases have great potential beyond the design
phase. This presentation describes how a development process was
implemented that ensures the utility of use cases not only for system
design, but also for quality assurance (QA) and documentation. Essential
use cases, which work well for user interface design, can be too vague
for later phases. QA and Documentation groups, in particular, have been
hesitant to adopt use cases, often preferring more traditional
approaches. This session introduces a new approach based on the concept
evolving use cases. Such use cases evolve from an essential form early
on to a more refined, more detailed representation of system
interaction. The final state provides the greatest utility to QA and
Documentation. The session will discuss best practices and lessons
learned from use case approaches employed within two projects. |

“Comparing Hierarchical Task Analysis with Use Cases" DeKoven,
Keyson This study compares two popular scenario-based
task-modeling approaches--use cases and hierarchical task analysis--that
aim to make clear user goals, user-product interaction, and system
design requirements. Both employ a static model of dynamic processes of
product usage. However, they differ in notation as well as approach.
Four teams of student designers trained in both task-modeling techniques
worked on a common design problem. The resulting designs are described
along with the design issues raised and the apparent relationships
between the task modeling technique used and the usability of the final
product.
"Supporting One Task with Many Devices" Lárusdóttir, Hvannberg
The complex world in which the same task can be accomplished by a
given user through many different devices raises many interesting design
issues. This presentation describes such a project in which a
user-centered approach was used. Models were used to describe user
roles, use cases, and a content model for each device. Since tasks
require users to go between devices, a navigational model and a more
abstract architectural model were developed. This session describes the
models and results from usability tests with 60 users in 4 countries and
reflects on the complexity of the user interface design.
"Conducting User Needs Analyses for Emerging Technologies"
Narasimhan
Strategic User Needs Analysis (SUNA) combines usage-centered user
role modeling with several investigative methods from human-computer
interaction and market research. On a small sample of twelve users
belonging to two focal roles the methodology was effective in
identifying the relevant characteristics, usage patterns, similarities,
and differences between the two roles. Further testing and refinement of
this methodology is suggested. |

| T32 - 4:00p-5:30p |
| Customer Success Metrics to
Target and Track Usefulness in Usage-Centered Design |
| Ron Pinder, Ronald Scott
Consulting, and Amy Dillon, Nortel Networks |
| |
Customer success metrics are
quantifiable, measurable, objective metrics for the value customers can
receive with a product. Such quantitative metrics act as drivers for
usefulness when writing essential user case narratives. They focus the
translation of product value to product requirements and enable the
tracking of value throughout development. Essential task modeling is
such a powerful and creative technique because essential models are
technology free. This advantage is used to effectively drive usability
into implementation. Customer success metrics use this proven
technology-free approach to capture and drive customer value with a
focus on usefulness. Written in simple, easily understood language, they
state a unit of measure and a quantified target. This presentation
examines the effectiveness of customer success metrics and essential use
cases based on real experiences in the field within different design
models (such as waterfall, participatory, or work oriented). It proposes
a link between usefulness and usability within usage-centered design. |
|
| T33 - 4:00p-5:30p |
| What It Really Takes to
Handle Exceptions in Use Cases |
| Rebecca Wirfs-Brock,
Wirfs-Brock Associates |
| |
The handling of exceptions and
alternative interactions is an important aspect of interaction design
and of software engineering. Well-conceived and thorough treatment of
exceptions is essential for designing reliable applications and for
making applications responsible, responsive, and adaptive to exceptional
conditions. Based on new ideas in responsibility-driven design, this
session will illustrate how to handle exceptions in use cases. |

Wednesday |
| Plenary - 9:30-10:30a |
| The Devilish Details: Best
Practices in Design for e-Commerce |
| Larry Constantine,
University of Technology, Sydney (Australia) |
| |
In business on the Web, as much or
more so than anywhere, the devil lies in the details. This presentation
will look at how careful attention to detail driven by usage-centered
design can markedly enhance usability and success in commercial Web
sites. |
|
| W11 - 11:00a-12:30p |
| Collecting and Using Customer
Stories |
| Thyra Rauch, IBM; Sarah
Redpath, Lotus Software; Gary Macomber, Consultant |
| |
Usability and aesthetic appeal are not
enough. Products must also be useful and must satisfy the usage needs of
the intended users. Useful solutions match what users are trying to
accomplish. This session shows how to apply a story-based approach to
understanding the goals and needs of users as well as their environment,
their interactions, and their tasks. Stories capture this understanding
in a rich and meaningful way. Well-crafted stories do not predispose any
particular implementation. They can be cast in a form useful for all
members of the design and development team throughout the design
process, providing a common vision of the users and their world and
establishing a shared communication vehicle early in the process.
Workshop exercises will enable participants to apply story-building
techniques and examples from our experience will be used as
illustrations. |
|
| W12 - 11:00a-12:30p |
| Innovating on Thin Ice:
Experiences with Usage-Centered Design in a Java Environment |
| Larry O'Brien, Consultant |
| |
In 1999, iMind Education Systems, a
dot-com startup, was trying to employ usage-centered design to develop
an innovative suite of tools for K-12 educators. Larry O’Brien, then
Vice President of Technology at iMind, managed the implementation of
these products. O’Brien will discuss schedule, technology, and teamwork
aspects of implementing both Java Swing and XML/XSLT-based,
cross-platform, browser-based applications in a multidisciplinary team.
Attendees will learn about the trade-offs that a software development
manager must make to balance innovative user interface design, schedule,
and technical capability. Examples will be given of components whose
functional and non-functional behavior caused users to literally gasp in
appreciation even as the company went from IPO-track to bankruptcy. |
|
| W13 - 11:00a-12:30p |
| Panel: Teaching
Usage-Centered Design in the University and in the Workplace |
| Robert Biddle, Victoria
University of Wellington (New Zealand);
Chris Chandler, UCLA; Marta Lárusdóttir, Reykjavik University (Iceland);
Lucy Lockwood, Constantine & Lockwood, Ltd.; Noble, Victoria
University of Wellington (New Zealand) |
| |
It has been argued that usage-centered
design is a teachable approach to model-driven visual and interaction
design. This panel of educators and trainers will share experiences and
explore some of the significant issues in teaching usage-centered
design. |
|
| W21 - 2:00p-3:30p |
| Extreme Design:
Usage-Centered Design in eXtreme Programming and Agile Development |
| Jeff Patton, Development
Team Leader, Tomax Technologies |
| |
Agile methods, such as eXtreme
Programming (XP), are proving to be effective strategies for rapid
development of high quality software. This session will focus on how
interaction design techniques, such as usage-centered design, can be
applied within the iterative development process of XP projects to
increase the likelihood of success. In addition to being more likely to
meet end-user expectations, interaction design has helped our team do
that sooner. Using interaction design as part of our process on a
regular basis allows us to guess right more often, hitting the target of
releasing usable software sooner. Based on practical project
experiences, recommendations are provided on how to practice an agile
form of usage-centered design and how to incorporate bits of interaction
design thinking into every day development and product planning
decisions. |

| W22 - 2:00p-3:30p |
| How Much Money Do You Earn
With Usability? A Cost-Benefit Analysis of Usability Engineering |
| Markus Weinlaender,
Siemens AG (Germany) |
| |
Usability engineering is an investment
over and above development costs. Usability promises higher customer
satisfaction and better products. However, it is extremely difficult to
know which efforts will lead to which improvements and what increase in
sales or revenues will result. This session introduces a new approach to
the usability engineering process: Cost-Benefit-Centered Design based on
comparative cost advantage (CCA). This method helps to distribute a
given budget reasonably. This research report shows how to calculate the
CCA and demonstrates that there is an optimum investment in usability.
Insufficient efforts are wasted, and too much usability engineering will
result in little additional benefit. |
|
| W23 - 2:00p-3:30p |
| Making a Difference:
Designers as Change Agents |
| Lucy Lockwood,
Constantine & Lockwood |
| |
The introduction of usage-centered
design and other usability practices into an organization often
challenges deep-seated organizational assumptions and may threaten
vested interests. Based on experiences within a number of organizations,
this session will look at how new practices in usability and visual and
interaction design are introduced into organizations and how they bring
about change. Specific suggestions will be offered of how usage-centered
design can function as a lever for organizational change. |

Pre-Conference Tutorials and Workshops
SUNDAY |
| P01 - 9:00a-5:30p |
| Performance-Centered Systems:
What They Are and How to Design Them |
| Gloria Gery, Gery
Associates |
| |
Systems that directly support work
performance are very different from those that are simply "usable" by
experts. This workshop will describe, discuss, and illustrate software
that is specifically designed to enable people who don't know what they
are doing to do it as if they did--while still accommodating expert
performers. These software applications integrate task structuring
support, knowledge, data, tools and collaboration methods--and
automatically produces required deliverables. The workshop will
address:
- the business pain that requires us to develop better alternatives
- the attributes and behavior of performance centered systems
- the development process necessary to achieve them
- who must be involved in design and development
- the politics of achieving them
- their benefits to people and to organizations
Many systems will be either demonstrated or illustrated, including
those supporting call center representatives, product designers,
analysts, managers, administrative personnel and consumers. |
|
| P02 - 9:00a-5:30p |
| Goal-Directed Methods for
Product Definition and Design |
| Kim Goodwin, Cooper
Design |
| |
The secret to creating great products
is to think about your users not just during design, but even earlier,
during product definition. What is the product and what does it do? This
course will introduce you to Cooper's Goal-Directed methodology for
creating breakthrough solutions as well as prioritizing improvements to
existing products. Participants will learn powerful ethnographic
research techniques, and will get hands-on practice with creating
Personas. Participants will then use their Personas in scenarios that
drive the design solution for an example product. |
|
| P03 - 9:00a-5:30p |
| Agile Usage-Centered and
Object-Oriented Design Techniques |
| James Noble, Robert
Biddle, Victoria
University of Wellington |
| |
This tutorial for designers,
developers, and usability professionals will cover the key practices for
agile usage-centered design and the transition to object-oriented
development. In the first half of the tutorial, we will experience
determining system requirements by identifying actors and stakeholders
and their essential use cases. Then, in the second half we will derive
system designs from the use cases, and evaluate our designs using
heuristics and design patterns. This tutorial is quite approachable for
people with only a light background in systems analysis or development,
and none in object-oriented programming or design. |

Post-Conference Tutorials and Workshops
THURSDAY |
| P04 - 9:00a-5:30p |
| Pushing the Envelope: Master
Class in Usage-Centered Design |
| Larry Constantine, Lucy
Lockwood, Constantine & Lockwood |
| |
This hands-on workshop with the
originators of usage-centered design is intended for experienced
designers who are already familiar with the basic principles and
techniques of usage-centered design and who are ready to take their own
work to the next level. The workshop will address advanced topics and
issues in modeling and design as shaped by the expressed needs and
interests of participants. The will provide opportunities for exploring
the current work and improving the skills of each participant through
discussion, coaching, and critical examination of work. Participants
will be encouraged to identify and build on their strengths as visual
and interaction designers and to understand and overcome their
limitations. A special area of attention will be design innovation. |
|
| P05 - 9:00a-5:30p |
| Object Modeling for User
Interface Designers |
| Rebecca Wirfs-Brock,
Wirfs-Brock Associates |
| |
User interface designers need to know
what is involved in the design of an application that is organized to
accommodate flexibility and change. Responsibility-Driven Design offers
practical advice for designing object-oriented applications. In a
responsibility-based model, objects play specific roles and occupy
well-known positions in the application architecture. Typically
"layered" applications separate objects in the user interface from an
application control and domain model layer. Each object is accountable
for a specific portion of the work. They collaborate in clearly defined
ways, contracting with each other to fulfill the larger goals of the
application. By creating a “community of objects”, assigning specific
responsibilities to each, we build a collaborative model of an
application. The objects we model are more than simple bundles of logic
and data; they are service-providers, information-holders, structurers,
coordinators, controllers, and interfacers to the outside world! Each
must know and do its part! Thinking in these terms enables you to build
powerful, flexible applications. This tutorial will be an
example-based tour of Responsibility-Driven Design which presents our
latest innovations and practical techniques, including new material from
a forthcoming book on object-oriented design (to be published fall
2002). Topics include: finding and evaluating the qualities of candidate
design objects, using CRC cards to model candidate objects, steps
involved in making the leap from use case models to object models,
realizing object roles with classes and interfaces, strategies for
assigning responsibilities, deciding on the control style of an
application, effective ways to describe collaborations, and techniques
for increasing a design’s flexibility and clarity. Attendees will be
have the opportunity to practice some design techniques through short
focused exercises. |

| P06 - 9:00a-5:30p |
| Implementing Usage-Centered
Designs In .NET |
| Larry O'Brien, Consultant |
| |
Microsoft’s .NET Framework provides a
well-architected class library of standard user-interface controls. But
great user interface designs combine standard controls with controls
tailored specifically for the task at hand. This programmer’s tutorial
will introduce the structure of .NET’s Windows Forms library, contrast
three architectures (Form-Event-Control,
Presentation-Abstraction-Control, and Model-View-Controller), and
demonstrate how custom controls developed with usage-centered principles
can be rapidly created, modified, deployed, and integrated directly into
Visual Studio .NET’s visual design tool. Sample code will be in C#, but
all principles are applicable across the range of .NET languages from
C++ to Visual Basic. |
