Introduction
IESS 1.0 2010
Service innovation in Architecture, Engineering and Construction (AEC) Sector
February 17, 2010
Specificities of the AEC sector
Building life-cycle overview
Main characteristics of the construction sector − Only one object produced − Short-lived teams − Independent and heterogeneous actors − Wide range of models and methods
More and more viewpoints − Restricted areas of responsibility − Internal strategies vs. project strategies

Introduction Adaptable Visualization Services AVS Design Case study Conclusion February 17, 2010 IESS 1.0 2010
Cooperation between actors
Cooperation is essential − To ensure project success − Difficulties
● Low predictable environment ● Communications not standardized
− Groupware solutions remain under-used
Service-based innovation − Cooperation support business
services − Sustainable Service Innovation
Process S2IP

CAISE, 21st International Conference on Advanced Information Systems. 8-12 June 2009. Amsterdam. LNCS 5565, pp. 319–333, 2009. February 17, 2010 IESS 1.0 2010
- Work practices standardization
- Services platform
prototyping - Pilot projects
experiments
- Requirements for commercial
platform - MDE approach
for rapid prototyping
- IPR management (“CRTI-weB”
trademark + open-source)
- Transfer to the sector (call for
tender) - Assessment of service delivery
(metrics)
- Feedback (users + SSII)
- Managing services evolution
Service value related processes
Focus on experiments of Business Services − Real construction projects (pilot-projects) − Aims
● Validating business services design ● First step of a sectorial change
management ● Standardization (practices + services)
Other results − Basic Human Computer Interfaces: − Interviews have shown that visualization
has to be adapted to its users… and their particular needs

Introduction Adaptable Visualization Services AVS Design Case study Conclusion
The concept of usage
Users needs related to − Their role in the cooperative activity
• e.g. in AEC: architect, engineer, owner of a building…
− Available business services in the collective project
Example of usage: architect need − Searching for specific documents in order to check
their consistency with main architectural plans
Defining usages − …As guidelines in User Interface (UI) design
IESS 1.0 2010 February 17, 2010
Introduction Adaptable Visualization Services AVS Design Case study Conclusion
Usage centered UI design
Usage centered [Constantine & Lookwood 2003]
− Software Engineering approach − Task oriented − Based on a collection of models − Incremental design with interconnected models
February 17, 2010 IESS 1.0 2010
Introduction Adaptable Visualization Services AVS Design Case study Conclusion
Adaptable and adaptive UI design
In Human-Computer Interface domain − Adaptable UI can be modified by users − Adaptive UI changes without explicit intervention of users
Emergent UI design by models − « To design once and generate many times » − Modeling different contexts of use (CU) − Modeling user interface elements evolution − Based on differents models: CU (user, platform, environment),
domain (task, concept), UI (elements)... [Sottet, J. et al. 2006]
February 17, 2010 IESS 1.0 2010
Introduction Adaptable Visualization Services AVS Design Case study Conclusion
From adaptive UI to Adaptable Visualization Service
Adaptive UI design − Simple user interface − In individual activity situations
UI design for collective activity − Another context : the actor context in the activity − Each actor has his own point of view
• A point of view : a set of visualization modes • Adapted to different usages
− Our approach • Supporting viewpoint building by usage • Choosing among a set of Adaptable Visualization Services
February 17, 2010 IESS 1.0 2010
Introduction Adaptable Visualization Services AVS Design Case study Conclusion
Adaptable Visualization Service
Visualization services − Visualize a collection of information − Remote service offering added value − Dedicated to a particular scientific domain − Useful for interpretation of a large volume of data − In an individual or collective visualization activity
Visualization Service design − Based on the concept of “dataflow” or “pipeline”
• Data filtering, geometric transformation, image rendering − Adaptable Visualization Services design is emerging [Hocová, P. et al. 2008]

Model-driven approach
Fundamental concepts of Model Driven Engineering (MDE)
− System [is represented by] Model [conforms to] Metamodel
− Transformations between models represented by
conforms to
Our needs : - Modeling usages and AVS
• From Business services and cooperation context models (past and ongoing works)
- By defining metamodels mappings

Usage-centered AVS design method
February 17, 2010 IESS 1.0 2010
Introduction Adaptable Visualization Services AVS Design Case study Conclusion
Usage – AVS models mapping
Focus on usage – AVS models mapping − Identifying possible AVS applicable in particular
usages
Mapping usages and AVS attributes − According to their metamodels

Part III
A first case study
IESS 1.0 2010 February 17, 2010
Inspired from our previous experiments − Groupware service system for construction
Example of usage − “Searching a document” − Ex. “I need the last meeting report”, ”I want to see a
picture of the project ”
Actual technique in the system − Searching in document tables − Filtering
Case study
February 17, 2010 IESS 1.0 2010
Introduction Adaptable Visualization Services AVS Design Case study Conclusion
Example : searching a document
Innovative AVS: Treemap + Cowerflow − Usage – AVS attributes mapping
Usage AVS
Role concerned Architect AVS Name Treemap + Coverflow
Name Searching a document
Main concept Document with normalized name
Structure Hierarchic structure of
variable surfaces, different colors Sub-concept Type, author
Information Quantity
Searching between a lot of documents, different quantity
with actors
Graphical attributes
High quantity of information with
proportional surfaces
Usage Frequency Rare Usability Easy practice, rapid learning
Context At office, on desktop computer
Required device
More efficiency on large interface

Example validation steps
Usages validation − 37 architect-specific usages identified − First step of validation based on pilot-projects + interviews − Work still in progress
AVS validation − AVS implemented in E.V.A. prototype − Experiments process
● Testing task ● Final scenario
− 17 experimenters confirmed the usage – AVS mapping − Experiment technique to be improved
Next steps − Improvement of usage and AVS metamodels
