Project Background
• Paper results form a group project in senior
level one semester software engineering
course (focus on both process & products –
all intermediary ones and final working
system with documentation)
• Capstone system development project using
tools in object paradigm & Unified Process
• Unified Process in 3 stages
– Requirements specification
– Design & implementation of baseline system
– Implemented system with all documentation
Project Description
• Tool for designing speech articulation
treatment plan – sponsor: Dr Sophia Hadjian
([email protected])
• Based on a consistent method for diagnosing
and treating speech articulation defects
• Method developed through research & testing in the
1950’s and 1960’s by Dr. Robert Milisen of Indiana
University
– Tribute to Dr. Milisen, former instructor and mentor of
project sponsor, who is currently in his 90’s

Use case diagram (use case descriptions)
Interaction diagram (Collaboration, Sequence)
Analysis class diagram
Package and class diagrams
Complete Use case model
Analysis and design mechanisms
ERD, Database schema
I/O design (GUI)
Test case design
Implementation Tools
• TextPad (for code writing)
• Java SDK and JavaHelp (freeware
utilities)
• HelpBreeze (a free trial program for
automatic help
• InstallAnywhere Now v. 4.5 (for
installation by user)
• JDBC and JDBC-ODBC bridge
Project Description Cont’d
• The “Milisen method,” a series of verbal
tests administered by clinician
• Results are adaptively altered
throughout treatment process
• Numerical/value – based system

Requirements Analysis
• Record test results in real time
• Establish basis for treatment design
through analysis of test results
• Design a customized treatment plan
Non-functional Requirements
•
•
•
•
User-friendly (non-technical)
Built-in online help system
Portable
Secured
System Description
• Single administrator can manage multiple
clinician access
• Multiple clinicians can each maintain a unique
set of clients
• Archival database storage of client data for
future statistical research
• Export client information
• Primary system use: Generate Treatment
Design

Database
Relational database (Access was used).
The main tables consisted of
• User
• Client
• Speech (organic causes of speech problems)
• Score (scores for different test parameters)
• TreatmentList (list of sounds for treatments)
• Feedback (level of responsiveness)
Speech Table
•
•
•
•
•
•
Spoken Language
Normal speech, Articulation
Voice, Frequency, hearing
Lips, Teeth, tongue, palate
Palate, Larynx, Nasal
Coordination
Implementation
• Coded in Java
• Classes consolidated into packages
• Packages distributed among team members
for implementation
• Relational Database Access with built-in
ODBC
• JDK comes bundled with JDBC-ODBC driver.
– JDBC (the DB interface built into Java)
– ODBC (MS’s DB connection interface)
• Powerpoint (for GUI prototype review)
Design Specification
• Three tiered architecture
– Top/Access layer: Database & help system
– Central/Business layer: Interfaces, data
processing
– Bottom/View layer: user interface
Educational value of project
•

•
Technical skills (learned in a group set up)
Planning skills (deadline fixed)
Testing (structured test plans)
Interpersonal skills (trusting team members)
Communications
Balancing work (fulltime load +
extracurricular)
• Teamwork (division of workload to match
interests)
