EASE (Empirical Approach to Software Engineering)
Project

• Goal of the project is to activate knowledge flow
  between industry and academia.

• Real field data
• On-the-spot knowledge

• Data analysis methods
• Scientific expertise

• Discovered improvement point
• Revealed know-how

• Objective evidence for evaluating validity of

Current Status of EASE Project

• Real field data were collected from some Japanese
  software development companies.
• Survey of the following data analysis methods was
  conducted.
• Case-Based Reasoning (CBR)
• Multi-Dimensional Scaling (MDS)
• Association Analysis
• Parallel Coordinate Plot (PCP)
• Mahalanobis-Taguchi System (MTS)
• Analysis of the data with the methods is in
  progress.

Example of Analysis MethodCase-Based Reasoning
(CBR)

• Evaluating similarities between an ongoing
  project and past projects.
• Estimating efforts to complete the ongoing
  project based on the similar past projects.

Estimated test cost 40.25
Similarity 0.94
Similarity 0.87
Similarity -0.77
5
Example of Analysis MethodMulti-Dimensional
Scaling (MDS)

• Evaluating similarities among projects in the
  same manner with CBR.
• Plotting the projects as dots on a
  two-dimensional coordinate system.
• where, the distance between dots depends on the
  similarity between projects.

Future Work

• Field data collection and survey of analysis
  methods should be continued.
• Know-how on method of the data collection and the
  analysis should be accumulated.
• Rewards to the industry and academia have to be
  returned.
• The journal paper can be rewards to the academia?
• What is the rewards to the industry? Debrief
  reports of the analysis?
