Agenda

Sponsor Background and Vision Old Risks and New Risks Process EMS Directory Phases Architecture and Database Schema Metrics Demo

Sponsor Society for Total Emergency Programs

(STEP) Council Dr. David Kluge, MD

Former President of STEPCurrent Editor of the EMS Directory

Rick Voight, RIT graduate has been providing business and marketing input

Project Background

EMS Directory: “reference document for EMS providers and related organizations”

Created in 1993 Four sections

Ambulance, Fire, Police, Hospitals, Nursing Homes Physicians Telephone and Admitting Hospitals Resources Protocols

STEP’s annual publication appears to be the only comprehensive EMS directory in the US

Vision

Write software that automates the creation of STEP’s annual EMS Directory

Get Regional EMS Councils to create directory for their region

Expand the EMS Online Directory to become State and then National

Old Risks

Dr. Kluge is not familiar with software engineering

Continuation of last year’s project Quickly learn about project and assess current

software

New Risks

Live site for entire Spring quarter Create testing database Check for connected users before updating and

rebuilding code on server Make sure didn’t check in file containing testing

database SQL address Troubleshoot users’ problems

Software Maintenance No one to maintain software after we leave Society of Software Engineers

Launch – Process

Iterative Approach Series of milestones that continually add more

functionality For each Iteration

Requirements -> Design -> Code -> Test

EMS Directory Phases

Information Gathering & Storage Enter directory information Allow organizations to update their information Store the directory in a database

Metrics Continued

Beginning of Spring realized that Spring milestones were too vague Made more, smaller milestones so we could track

progress

Reasons for slippage Dynamic SQL generating more difficult than

anticipated for searching Lack of organization information and expertise for

printing aspect

Metrics Continued

Test cases per requirement Hazmat: 4 / 37 = 0.11 Initial Rewrites: 36 / 28 = 1.292nd Rewrite: 55 / 33 = 1.67

Hasn’t changed

Bugs by Severity

Low, 13, 37%

Medium-Low, 8, 23%

Medium, 5, 14%

Medium-High, 8, 23%

High, 1, 3%

Metrics Continued

35 total bugs 74% Medium or

Lower Many Low Severity

bugs were fixed and not recorded

Assessment

Has Worked: Division of the architecture to separate team

members Communication: Teleconferences & Email Separate Testing Database

Hasn’t Worked: Working directly on the server for ASP & C# Printing took excessive amount of time

Better suited for someone with that expertise (printing major)
