摘要

When reviewing and evaluating the basis of estimate for mission phases, it is important to understand how the labor basis of estimate compares with past NASA science missions. As such, it can be very valuable to understand the labor loading [Full-time Equivalents and Work Year Equivalents (FTE/WYE)] for historical missions and how the final, actual staffing levels compare with the initially planned staffing levels for these missions at certain project milestones. The FTE Tool11Justin F. McNeill, Jr. et al., “FTE Tool, a Practical Tool for Analyzing Staffing Levels and Cost Across Missions,” IEEE Aerospace Conference, Big Sky, Montana, 5 March 2014. is a legacy, Microsoft©Excel application-based plotting capability built upon a detailed repository of mission programmatic data. The tool has been in use as a tool for comparative analysis in staffing profiles since 2009. It provides high-level views of the historical data for twenty-six NASA missions for development Phases C and D as well as the operations Phase E. FTE Tool is available via the One NASA Cost Engineering Database (ONCE). To modernize and enhance this capability, a new web browser-based application, aView, is being developed on an open source software platform: chart.js for its front-end and a SQLite database for its backend. The name aView is short for Aerospace Viewer of NASA Project Staffing Data. As with the FTE Tool, in aView, the user may select from a set of predefined plots that give a wide variety of views into the missions' programmatic data. One can plot FTE/WYE versus dollar cost for multiple missions during specific phases of development or during operations. Other plots provided by the tool include planned versus actual annual FTE/WYE and FTE/WYE and dollar cost per fiscal year. In addition to the plotting capabilities, aView is a repository of fairly detailed mission information and data. Individual fact pages have been compiled for each mission. Each page provides an illustration of the mission's space vehicle and instruments and the associated technical data and programmatic information, i.e., estimated and/or actual program cost, major development milestones including launch date, launch vehicle, mission trajectory, links to mission website. All of the fact pages are crafted based on information drawn from the NASA Cost Analysis Data Requirement (CADRe) documents and from the project's monthly management/status reviews (MMR/MSR). This paper will discuss the general capabilities and construction of aView. In addition, the paper will explore some use cases (scenarios of application) to illustrate how this application may answer specific programmatic questions. The presentation may include a brief video or live demonstration.

McNeill，Jr.等人，“ FTE工具，一种用于分析整个任务的人员编制水平和成本的实用工具”，IEEE航空航天会议，蒙大拿州，Big Sky，2014年3月5日。基于详细的任务程序化数据仓库的绘图功能。自2009年以来，该工具一直用作人员配置文件中进行比较分析的工具。它为发展阶段C和D以及运营E阶段的26个NASA任务提供了历史数据的高级视图。FTE工具可通过一个NASA成本工程数据库（ONCE）获得。为了实现现代化并增强此功能，正在开源软件平台上开发基于Web浏览器的新应用程序aView：其前端为chart.js，后端为SQLite数据库。名称aView是NASA项目人员配备数据的Aerospace Viewer的缩写。与FTE工具一样，在aView中，用户可以从一组预定义的绘图中进行选择，这些绘图可以为任务的程序化数据提供多种视图。在特定的开发阶段或运营期间，可以绘制多个任务的FTE / WYE与美元成本的关系图。该工具提供的其他图表包括计划年度与实际年度FTE / WYE和FTE / WYE以及每个会计年度的美元成本。除了绘图功能外，aView还包含相当详细的任务信息和数据的存储库。已为每个任务编辑了单独的事实页面。每页都说明了特派团的航天器和仪器以及相关的技术数据和方案信息，即估计和/或实际方案费用，主要的发展里程碑，包括发射日期，运载火箭，任务轨迹，与任务网站的链接。所有事实页面都是根据NASA成本分析数据需求（CADRe）文档和项目每月管理/状态审查（MMR / MSR）得出的信息制作的。本文将讨论aView的一般功能和构造。此外，本文还将探讨一些用例（应用程序场景），以说明该应用程序如何回答特定的程序性问题。该演示可以包括简短的视频或现场演示。
