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

Architecture

Team TFY used Software Architecture Analysis Method (SAAM):

Architecture

Three 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

MethodologyOO 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 needrefactored 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
