| Problem | A recent new initiative at NASA IV&V is the use of early lifecycle model-based validation. Elsewhere in the agency, there is increasing interest in agile process, assertion-based analysis, Eclipse-based programming, Matlab-based automatic code generation, simulation-oriented development cycles, etc. How are we to assess the benefits vs cost trade-offs on all these new methods? How are we to make future plans for the agency, given some much change in current practices? Using traditional methods, there are no answers to these questions. Such a study is hindered by the local tuning problem. Software process models are most accurate after they have been tuned to local data. Unfortunately, the data required for local tuning is difficult to obtain, especially across multiple organizations . This is due to the business sensitivity associated with the data as well as differences in how the metrics are defined, collected and archived. Sometimes, the data is not even archived (e.g. after two years we were only able to add 7 records to our NASA wide software cost metrics repository). |
| Objective | A characterization of projected changes to NASA?s IV&V software development processes over the next 2 to 20 years. A stability analysis that checks for stable conclusions existing in that space of projected changes. Assume success, a set of policy recommendations to NASA for changes to current software practices to better meet the expected changes to NASA?s software development processes. |
