Methods for Improvement

Quality Upgrade Results

Software Quality

• Upgrading the software quality was the primary task for this semester

• State at beginning of semester: No thorough evaluation completed 60 unresolved defects Issues with IE 7 functionality Inconsistent appearance and functionality Lack of code commenting 202,000+ lines of code

Methods for Improvement

• Evaluation

• UI Upgrade

• Code Cleanup

• Defect Fixing

Defect Fixing

• Key method of improvement is defect fixing
