COSOSIMO Workshop Results © USC CSE 2005 COCOMO Forum October 2005 Workshop Objectives Clarify the Lead System Integrator (LSI) activities to be estimated by the COSOSIMO model Investigate candidate approach(es) for estimating the LSI program/business management effort Determine whether an SoS calibration of COSYSMO warrants further investigation as a viable approach for estimating LSI technical effort Begin converging on a relevant and complete set of parameters for the COSOSIMO model that are easily discerned in the early stages of SoS development

COSOSIMO Workshop Results © USC CSE 2005 COCOMO Forum SoS Program WBS Discussion (Lead by Gan Wang, BAE Systems) Provided much deeper understanding of LSI role and associated activities Provided good framework for continuing discussions on “A day in the life of an LSI” The SoS Program The SoS in Operation Spiral AlphaSpiral BravoSpiral CharlieProgram Office Plan- Driven Team IV&V Team Agile Team Level 0 Level 1 Development

COSOSIMO Workshop Results © USC CSE 2005 COCOMO Forum LSI Activity Discussions LSI Activities –Recommendation: LSI activities should be broken out into the following categories Program/business management activities (as opposed to technical management activities) Technical activities (which include technical management activities identified in EIA 632) –Results: Generated another list of LSI activities to compare with July 2005 list No significant new activities identified LSI Effort Program/Business Management Effort Technical Effort Proposed scope for COSOSIMO if technical can be estimated using COSYSMO SoS calibration Investigate possibility of COSYSMO SoS calibration to estimate this part

COSOSIMO Workshop Results © USC CSE 2005 COCOMO Forum Review of Candidate Program Management Cost Estimation Model Provided by Gary Constantine, Raytheon….

COSOSIMO Workshop Results © USC CSE 2005 COCOMO Forum Discussion Results Sample cost model helped clarify “management activities” to be estimated –Should focus on program/business management effort –Technical management should be part of technical effort Sample cost model (in Excel) will be provided as part of minutes to COSOSIMO Working Group End of workshop question: After all of the discussions on LSI technical and management activities, is a COSOSIMO with two primary parts (management module and an SoS-calibrated COSYSMO) is a viable way to proceed? ANSWER: (Almost?) unanimous yes

COSOSIMO Workshop Results © USC CSE 2005 COCOMO Forum Second Question: Viability of COSOSIMO Data Collection Affiliates queried about the availability of SoS LSI data in their organizations –Whether LSI-only data can be obtained –Whether data can be broken out into management and technical buckets General consensus: Data is available, just not as many programs as they had for COSYSMO at the system level Discussed options for collecting data from US government LSI organizations—several attendees took the action to identify potential points of contact

COSOSIMO Workshop Results © USC CSE 2005 COCOMO Forum Action Items J. Lane Action Items –Update LSI activity descriptions with respect to the SoS WBS terms –Make a first cut at identifying WBS boxes for each of the LSI categories: management and technical –Update CSE COSOSIMO web page COSOSIMO Working Group Attendees –Provide LSI points of contact for data to J.
