Evolving toward object-oriented technology in large organizations (panel)

The Multimission Three-Axis Attitude Support System (MTASS) had the most modest use of 00 technology. On such systems, there was always one big file for all sensor data. As sensors vary from mission to mission, interfaces and file formats need to be revised, so there hasn’t been a lot of reuse. On MTASS, we employed a single file for each sensor and have interface code to each file. We didn’t use 00 design, but we at least grouped data with operations on the data. This very modest usage of 00 concepts during the coding phase has helped increase reuse from 20% of the code to 70% of the code.
