Agenda Data Reduction Building an Estimate Metrics Manual Application Domains 3

Data Reduction Level of data issues Domain prioritization (top 7 identified) Program reporting differences Add manual appendix listing systems used in domain analysis Manual should provide advice on system decomposition for estimation using the domain categories Focus for users primarily in concept exploration and contract award (MS B or MS A if SLOC known) 4

Normalizing Size Reviewed SLOC definitions – no changes recommended COTS estimation parameters differences Reviewed backfilling assumptions for equivalent size – no changes Model-based sizing issues –Different model types Consider requirements-based sizing 5

Reuse Parameters SEER rework calculation parameters would need revision; many conflicts –Will not include in manual SLOC conversion factors –Report as range Modified size conversions –Fixes identified 6

Effort Normalization Backfilling approach reasonable with provided data –More interviews about missing data would help 7

Multi Builds Evaluate approach in future about combining build data 8

Team Experience Iterate on effort multipliers Provide guidelines on estimating TXP 9

Distribution Percentages Will provide domain-specific values for estimating effort allocation to phases 10

Metrics Manual Outline Add guidance on estimating integration effort –3 approaches identified Maintenance data available in Summer Address non-counted labor hours 11

Application Domains Survey taken on failure impacts Notes taken to crisp up domain definitions 12
