the increasing demands on our
engineers

Two Capstone projects
• Machine Reservation System
• Project Tracking Tool

Machine Reservation System
• GemStone has a number of machines
– Shared among developers and testers
• Want to keep machines as active as
possible
– Run tests on weekends and off hours

Machine Reservation System
• Current system doesn’t scale
– An engineer manually edits text file to
make reservation
– A tester has to check file before running
tests or using machine
– Allows two people to think they have
the machine reserved
– Hinders automated testing execution

Machine Reservation System
• We’d like a new system
– Reservation files readable by humans
and machines
– Java API that can be invoked by our
testing framework
• Before a test is run, it can check to see if
someone else has the machine reserved

Machine Reservation System
• Tools to manage reservations
– Detect reservation conflicts
– Remove reservations that have expired
– Tell us which machines are currently
available

Project Tracking Tool
• GemFire is developed using an agile
software development practice called
“Scrum”
– Small teams, 30-day development “Sprints”
– Development tasks are prioritized in a
“Product backlog”

Project Tracking Tool
• We currently use an Excel
spreadsheet to track progress
– Nice charts and printing capabilities
– Macros and formulas are getting
complex
– Not platform independent

Project Tracking Tool
• We’d like a new GUI that is designed
especially for Scrum tracking
–
–
–
–
Create and manage development tasks
Save backlog to file
Update progress as tasks are completed
Chart work completed and time
remaining
