This paper reports on the results of a follow up study conducted on seven JPL missions completed on or near launch since 1999. The objective is to determine to what extent the recommendations were implemented and whether they had any impact.

In this paper, we will summarize the software trends and their impact on the cost of developing flight and ground software.
This paper describes the approach and algorithms used to generalize the paired ratio comparison matrix technique to use information inherent in multiple estimates, multiple reference projects, and estimator range information to generate estimated effort and size distributions.
The presentation will provide a brief overview of the SQI measurement program as well as describe each of these models and how they are currently being used in supporting JPL project, task and software managers to estimate and plan future software systems and subsystems.
In this talk we will discuss how uncertainty has been incorporated into the JPL software model, probabilistic-based estimates, and how risk is addressed, how cost risk is currently being explored via a variety of approaches, from traditional risk lists, to detailed WBS-based risk estimates to the Defect Detection and Prevention (DDP) tool.
NASA's JPL managed by Cal Tech is currently investing ways to improve its ability to increase the cost estimation accuracy early in the project life cycle.
