This presentation provides a detailed review of the cost estimation process - including space program ... cost elements, cost estimate methodology, techniques, learning curve analysis, and more. In addition, this presentation includes guidance on how to develop a cost estimate for unique programs or programs that require an independent cost estimate.
This handbook describes the cost estimating process from receiving a customer request through developing ... and presenting the cost estimate to project stakeholders. Smaller programs can use the Analogy Cost Estimating methodology outlined in section 2.2 of the handbook. Included in this resource are multiple links to other useful models, tools, and handbooks that will help in cost and schedule management.
This article outlines the basics of the cost estimation process and how to apply it to a smallsat mission. ... Multiple tools are provided in this document including the NASA Instrument Cost Model (NICM), Small Spacecraft Cost Model (SCCM), and NASA Cubesat Or Microsat Probabilistic Analogy Cost Tool (COMPACT). Slide 24 is especially useful in guiding users through the cost estimating process - from gathering data to implementing the various cost models.
This thesis discusses two widely used cost estimating models, the Small Satellite Cost Model (SSCM) and ... the NASA/Air Force Cost Model (NAFCOM), and the gap in cost estimates for nano- and picosatellites, specifically. With a smaller database of analogous smallsat missions, it is difficult for nano- and picosatellite teams, especially university teams, to develop accurate cost estimates for their smallsat mission.
These appendices include a number of resources that are relevant to the development of satellite cost ... and schedule estimates - including advice on work breakdown structure (WBS) development, models and tools, and specific guidance for software cost estimation.
This report provides guidance on conducting reviews and estimating resources for space acquisition programs. ... Chapters 3 and 4 explain the review and cross-check processes that acquisition analysts use to verify and validate satellite cost estimates. Relevant historical information on space systems and cost drivers are also included in this article.
SSCM is an open source cost modeling tool developed specifically for small satellite cost analysis. Traditional ... satellite cost models usually overestimate program costs due to added complexity and risk associated with larger satellites. The SSCM tool uses data from over 80 different small satellites to create cost estimating relationships (CERs) for total program costs.
This article provides useful information and mathematical equations for estimating accelerated life testing ... (ALT) distributions. ALT can be extremely costly and time-intensive, by developing a plan prior to ALT it reduces the risk of failure during the design phase. This resource will help in the planning process prior to the actual implementation of ALT.
This conference paper presents a useful smallsat mission preliminary design. Of value to a general smallsat ... audience are the sections on constellation design, responsiveness, spacecraft sizing, launch vehicle, and cost estimation. This paper does not go into significant technical detail; however, it can serve as a useful case-study and addresses several high-level design details that should be considered by smallsat conceptual design teams.
This guidebook is a "collection of of recommended best practices and ready references to expedite research ... and technology (R&T) development projects" for NASA's Small Spacecraft Technology (SST) program. This resource is specifically targeted at SST projects; however many of the sections include best practices that can be valuable to a general smallsat audience. This section of the guidebook addresses project resources and cost estimation resources and tools.
