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 STEP  Current 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 Document Generation  Create a document template  Generate CSV for template Information Searching and Editor Functions

Status Database/Stored Procedure Refactor Complete Web Service Implementation Complete Web Application Implementation Complete InDesign / PDF file can be generated for region

Architecture

Database Schema

Metrics  Slippage Chart  # of test cases per requirement  Pie chart of defects by type

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 = 1.29  2 nd Rewrite: 55 / 33 = 1.67 Hasn’t changed

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 &  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)
