AN ADAPTIVE SORTING FEATURE FOR HOPE
ADAPTIVE AHP AND
USER MODEL DRIVEN APPROACH
Team Think For You
Outline Introduction Process Requirements Engineering Architecture Detailed Design Testing Demo Extensibility Conclusions
IntroductionThe Problem:
Who’s Affected?
Goals (How we solve the problem)Capture multiple types of contextual info. about user’s
past behaviorSort options using a combination of captured info. Display options in order of user’s most likely need
Too many options/config. settings in HOPE
Our Process (Re)planning, Risk mitigation, issues resolution,
SDM, tradeoff analysis, WBS, SVN SW Dev. Process
Interleaving, Iterative (Agile) and IncrementalFluid Teams(RE, Arch, DD, Implementation, QA) 2 Iterations:
Iteration Activities
1 • Problem + Domain analysis• POC with 1 usage stat. type (frequency)
2 • 2 usage stat. type (frequency + time of day)• Adaptive AHP, integration and testing
Requirements (Analysis) – One Example
ArchitectureTeam TFY used Software Architecture Analysis Method (SAAM):
ArchitectureThree options considered:
1. Delegate the responsibility of filtering things and actions to a module that wraps data access and updates statistics
2. Refactor existing architecture into a layered configuration, then extend business logic layer for context awareness
3. Map all the points of change in the current system to extend with context-sorting logic

Detailed Design Methodology
OO modeling, SDM, issue and conflict resolution Scientific research Design patterns
Adapter, Template, Strategy, Observer... Design principles
High cohesion (single responsibility) and low coupling (data dependency)

Conclusion Our Contributions to HOPE:
Use of contextual information to sort icons in order of user's most likely need
refactored HOPE code to make it more maintainableformal model checking to test aspects of our modeldesign is easily extensible to allow for future addition
of more types of contextual information as criteria in the sorting
