A methodology for assessing the value of manufacturing quality requirements to the final product, QVAL, is presented. The prime objective of this project was to reduce the Manufacturing Quality Requirements (MQR) that the Jet Propulsion Laboratory (JPL) imposes on internal and contracted electronics assembly organizations to the minimum number of requirements of significant value to the product.

The U.S. Census Bureau (Bureau) conducted the Count Question Resolution (CQR) program to correct errors in the count of housing units as well as dormitories and other group living facilities known as group quarters. GAO was asked to assess whether CQR was consistently implemented across the country, paying particular attention to whether the Bureau identified census errors that could have been caused by more systemic problems. GAO also evaluated how well the Bureau transitioned to CQR from an earlier quality assurance program called Full Count Review.

This report is a codification in two parts of conventional aircraft handling qualities criteria. The results of this effort are to serve as an intermediate design guide in the areas of lateral-directional oscillatory and roll control. All available data applicable to these problem areas were considered in developing the recommended new criteria. Working papers were sent to knowledgeable individuals in industry and research agencies for comments and suggestions, and these were incorpo-rated in the final version of this report. The roll handling qualities portion of this report uses as a point of departure the concept that control of bank angle is the primary piloting task in maintaining or changing heading. Regulation of the bank angle to maintain heading is a closed-loop tracking task in which the pilot applies aileron control as a function of observed bank angle error. For large heading changes, the steady-state bank angle consistent with available or desired load factor is attained in an open-loop fashion;it is then regulated in a closed-loop fashion throughout the remainder of the turn. For the transient entry and exit from the turn, the pilot is not concerned with bank angle per se, but rather with attaining a mentally commanded bank angle with tolerable accuracy in a reasonable time, and with an easily learned and comfortable program of aileron movements. In the lateral oscillatory portion of this effort, in defining requirements for satis¬factory Dutch roll characteristics, a fundamental consideration is the fact that the motions characterizing this mode are ordinarily not the pilot's chief objective. That is, he is not deliberately inducing Dutch roll motions in the sense that he induces rolling and longitudi¬nal short-period motions. Dutch roll oscillations are side products of his attempts to control the airplane in some other mode of response, and they are in the nature of nuisance effects which should be reduced to an acceptable level. In spite of its distinction as a side effect, adequate control of Dutch roll is a persistent handling qualities research area and a difficult practical design requirement. The diffi¬culties stem from the many maneuver and control situations which can excite the Dutch roll, and from its inherently low damping. Since any excitation of the Dutch roll is undesirable, the effects of disturbance inputs are almost uniformly degrading to pilot opinion rating. Never¬theless, removal of such influence does not eliminate the need for some basic level of damping. A worthwhile approach to establishment of Dutch roll damping requirements is to first establish the basic level, and then to study the varied influences of the disturbance parameters. This approach provides the basis for the material contained in this report.

This report discusses the extent to which (1) states are refining designated uses when necessary and the Environmental Protection Agency (EPA) is assisting states toward that end and (2) EPA is updating its criteria documents and assisting states in establishing criteria that can be compared with reasonably obtainable monitoring data. Included are recommendations to the Administrator of EPA to provide additional guidance regarding designated use changes to the states and regional offices that clarifies when a change is appropriate, what data are needed to justify the change, and how to establish subcategories of uses; follow through on the agency's plans to assess the feasibility of establishing a clearinghouse of approved designated use changes by 2004; set a time frame for developing and publishing nationally recommended sedimentation criteria; develop alternative, scientifically defensible monitoring strategies that states can use to determine if water bodies are meeting the criteria; and develop guidance and a training strategy that will help EPA regional staff determine the scientific defensibility of proposed criteria modifications.

This bibliography contains information selected after a thorough review of journals, conferences, technical reports and theses, books, and numerous miscellaneous publications (newsletters, memorandum, fact sheets, news releases). Many sources were used to compile the bibliography, including online databases and manual searches of journal indexes and newsletters. The selected items provide information on the underlying principles and methods, performance indicators, case studies in government and industry, lessons learned, and DOD initiatives for instituting TQM. The bibliography is divided into sections by the type of publication and a title listing is provided at the end of the document for a quick review of content.

The National Committee for Quality Assurance (NCQA) has completed work on a project related to quality measurement and reporting at the level of the physician office practice. The project was supported by funding from The Commonwealth Fund and the Agency for Healthcare Research and Quality (AHRQ). The core activity of the project was an invitational conference held October 10, 2002 in Washington D.C. Attendees included experts and users of performance measurement at the physician level including: directors; leaders of quality measurement from the Veterans Administration (VA) and the Centers for Medicare and Medicaid Services (CMS); and staff from AHRQ, The Commonwealth Fund, the Robert Wood Johnson Foundation and NCQA. Seven invited papers were prepared to give participants a common level of knowledge and understanding prior to the conference. The papers provided a review and synthesis of work to date, an examination of existing barriers, and suggestions for addressing those barriers with further research. The papers were selected to review three major approaches to measurement at the office practice level including: (1) Clinical performance measures; (2) Survey-based measures; (3) System-based measures; and to address cross-cutting statistical issues.

Demographic Full Count Review was one of a number of quality assurance programs the Bureau of the Census developed for the 2000 decennial headcount to help ensure the completeness and accuracy of census data. Analysts were to identify, investigate, and document suspected data discrepancies or issues in order to clear census data files and products for subsequent processing or public release. Bureau reviewers were to determine whether and how to correct the data by weighing quality improvements against time and budget constraints. According to bureau officials, because the bureau lacked sufficient staff to conduct Full Count Review on its own, it contracted out some of the analysts work to members of the Federal-State Cooperative Program for Population Estimates (FSCPE), an organization composed of state demographers that, since its inception in 1973, has worked with the bureau to ensure accurate state and local population estimates. The bureau believed that FSCPE members knowledge of the demographic characteristics of their respective states could help the bureau review data files and products, including politically sensitive apportionment and redistricting data files known as public law data. This letter responds to your request to review the FSCPE members participation in the Full Count Review program. As agreed with your offices, we provide information on (1) the number and kinds of data issues identified by FSCPE members and bureau analysts, (2) how the bureau used the information developed during Full Count Review, and (3) lessons learned from the conduct of Full Count Review that can help the bureau plan for the 2010 Census. This report is the latest in a series of reviews that examine the results of key census-taking operations and highlight opportunities for reform.
