1. COCOTS Presentation for CSCI 577 Fall 2006 Jesal Bhuta jesal@usc.edu

2. 2 Outline  Modeling Context  COCOTS Cost Sources  Current Status  Tool Demo

3. 3 COTS Modeling Problem Context 1 (COTS Components as Application Elements, Infrastructure, or Tools) COTS and Custom Applications Components ---------------- New Modeling Problem ---------------- COTS as Infrastructure COTS as Tools ( COCOMO IIparms PVOL,PLEX) ( COCOMO II parms LTEX, TOOL) Cost Modeling Currently Addressed Within COCOMO II: COTS as Infrastructure and Tools

4. 4 COCOTS Cost Sources

5. 5 About COCOTS  Three Sub-models –Assessment sub-model –Tailoring sub-model –Glue code sub-model  Mathematical form of each sub-model is different –However, a common feature is estimates based upon classes of COTS components being examined –Example COTS classes: GUI builders, operating systems, databases, word processors, etc –See demo later

6. 6 COCOTS Architecture

7. 7 Current Status  Calibrated on 20 data points  Project Domains –Air Traffic Management –Business (including databases) –Communication, Navigation, & Surveillance –Logistics –Mission Planning –Operations –Web-based Maps
