Architecture The Constraint
Introductions
The Project
Main Goals for Semester
Reflection
Preparation for Summer

• Constraint The existing system
• Consequences Maximize use of legacy architecture
• Partial Architectural Reconstruction
• Verification of legacy architecture
• Extensive investigation of legacy code and
  existing documentation
• Since ACDM is our process, we did this through
  experiments

Reflection Process
Introductions
The Project
Main Goals for Semester
Reflection
Preparation for Summer

• Good stuff
• Ramp-up plan for spring
• Role distribution
• ACDM inspired by TSP
• Room for improvement
• Detailed design process was not structured
  enough ? define goals for detailed design

22
Reflection Planning Tracking
Introductions
The Project
Main Goals for Semester
Reflection
Preparation for Summer

• Good stuff
• Planning process worked well
• EV provides motivation
• More detailed time tracking for admin tasks
• Room for improvement
• Finer grained tasks for EV? Getting EV when task
  is ready for review
• Under-estimated new tasks ? Build in buffer time

23
Reflection Architecture
Introductions
The Project
Main Goals for Semester
Reflection
Preparation for Summer

• Good stuff
• Experiments are useful for learning about the
  legacy system
• Also helps with problem of implementation not
  matching the architecture
• Architectural reviews gave us confidence in the
  architecture
• Team walkthroughs helped consolidate knowledge
  within team
