O ganho de competitividade das organizações está relacionado com quem proporciona serviços ou produtos de forma rápida, com custos mais baixos e com mais qualidade e segurança. Dentro deste cenário, o atendimento destes quesitos reflete na busca por um aumento de eficiência, satisfação do cliente e lucratividade incentivando constantemente as organizações a procurar e identificar novos fatores competitivos, explorando cada vez mais novos métodos de operação e entrega. Conseqüentemente, a introdução de melhorias incrementais ou de um novo desenho de processos são propostos e muitas vezes acompanhados da implementação de sistemas automatizados. Sistemas Workflow vêm ao encontro destas estratégias de redesenho e otimização dos processos de negócio através da automação dos seus fluxos de trabalho, tornando-os mais ágeis, seguros, confiáveis e proporcionando um diferencial para a organização. Porém, são poucos os estudos associados à avaliação do seu impacto sobre processos. Apresenta-se e discute-se os principais conceitos e impactos relacionados a esta tecnologia e associados a processos e indicadores de desempenho, utilizando o método de estudos de casos múltiplos. Conclui-se que os impactos na utilização deste tipo de tecnologia resultam em melhorias para o processo em todas as dimensões consideradas (custo...

A qualidade na área de saúde pública ainda é um movimento incipiente no Brasil. Insuficiência de recursos para investimentos e melhorias, mas também falta de eficácia e efetividade, frágil acolhimento dos usuários, baixo impacto das ações de saúde sobre os problemas da população, se constituem ainda problemas evidentes. Torna-se extremamente necessário e urgente apontar possibilidades de intervenção nesta realidade. Não basta melhorar o financiamento na saúde, é preciso corrigir os procedimentos organizacionais para reduzir custos, eliminar desperdícios, retrabalho, e reduzir a variabilidade nos processos de trabalho. O que deve mover a administração pública é a boa utilização do orçamento, e não o aumento de lucro. Sendo assim, a área de saúde pública é um ambiente único e desafiador para implantar mudanças na forma de Gestão. Esta dissertação tem a finalidade de retratar como a Gestão da Qualidade e o método de Redesenho de Processos pode ser uma estratégia para o Desenvolvimento Organizacional nos Hospitais Públicos Universitários, através do relato da experiência no Hospital de Clínicas da UNICAMP. A realidade encontrada pelo redesenho nos processos do HC-UNICAMP foi uma grande quantidade de mudanças fáceis de implantar nos processos vigentes. Os trabalhos permitiram avançar nas interfaces entre as áreas...

Dissertação apresentada como requisito parcial para obtenção do grau de Mestre em Estatística e Gestão de Informação; In recent years, social networks have assumed an important role in life of millions of people and more recently in life of organizations, that are discovering their potential. We are living in a context of a generalized crisis in Europe and in the world but we are also live in a globalized Europe an world, where achieving competitive advantage depends much of means either than productive ones. Some of this factors have evolve and are now almost inseparable of organizations allowing to built holistic vision of their systems people, information and equipments. Knowledge management, information management and business process management are recognized as a source of competitive advantage as well, but just like social network not all organizations already understand their potential. For the development of the thesis we did a qualitative research based on a literature review and a case study on a Portuguese airline whose key findings are centred on the fact that social networks, by bring voices that are dispersed, enable to organizations to have more and better knowledge which can be used in process redesign and thus achieving competitive advantage. This study contributes to understand how SN can help organizations improve their Business Process and how Business Process Management (BPM)...

The United States Coast Guard Port State Control (PSC) is a port entry tracking process, which is currently performed primarily using paper and pencil. This thesis examines the feasibility and effectiveness of redesigning the PSC process in light of modern Business Process Redesign methodologies that incorporate contemporary information technology. The current process is modeled using the automated redesign tool, KOPeR, to identify pertinent redesign recommendations. A redesign of the process is completed using the recommendations provided by KOPeR and leveraging existing Coast Guard infrastructure and technology solutions. The effectiveness of the redesigned process is evaluated against the current process by using discrete event stimulation models to compute the relative cycle times. Three different scenarios are run which show a potential annual reduction in manpower ranging from two to four person years. A Web-based prototype system, Re-engineered Port System (RePortS), is developed using basic tools such as Microsoft Access and Active Server Pages to demonstrate the feasibility of implementing the required functionality. The benefits of replacing the current manual system with a Web- based system are, reduced cycle time, increased accuracy and consistency in the process.

Approved for public release; distribution is unlimited; The Naval Postgraduate School CubeSat Launcher (NPSCuL) is a five-sided structure capable of carrying up to 24 CubeSats to orbit. The vibration test environment for CubeSats flying on NPSCuL on the Atlas-V is extremely harsh, partly due to the input vibration environment from the launch vehicle itself, and partly due to amplification from the NPSCuL structure. This thesis documents the implementation of a relatively new technology, Force Limited Vibration Testing (FLVT), and the design of a stiffer structure to reduce the vibration environment for NPSCuL payloads. Most acceleration-controlled vibration tests result in significant over-test. FLVT limits shaker forces, producing more realistic tests and potentially provides relief to payloads. Additionally, increasing the stiffness of NPSCuL using an isogrid design, aimed to increase its first-fundamental frequency, could result in less displacement at higher frequencies for a given amount of input energy, possibly improving the payload vibration environment. It was found that FLVT was very successful in reducing vibration environments for NPSCuL payloads. Although redesigning NPSCuL using an isogrid design achieved the goal of increasing system stiffness...

Las nuevas tendencias gerenciales en la administración publica sanitaria abogan por un mayor protagonismo de los ciudadanos en la toma de decisiones de los procesos asistenciales y por una mejora de la calidad de los servicios hospitalarios ofrecidos. Conscientes de esta realidad, las direcciones hospitalarias se están caracterizando por el creciente interés en desarrollar proyectos de mejora de sus procesos asistenciales básicos, utilizando para ello en algunos casos herramientas como la denominada Reingeniería o Rediseño de Procesos que supone una demolición controlada y drástica de los procesos estratégicos de valor agregado y de los sistemas, las políticas y las estructuras organizacionales que los sustentan para optimizar los flujos del trabajo y la actividad de una organización. En este artículo estudiamos el Rediseño de Procesos desde un punto conceptual, revisando las fases necesarias para su puesta en marcha y analizando su aplicabilidad potencial en el ámbito Hospitalario Público. Concluimos resaltando que la práctica del rediseño de procesos no es, según sus principios conceptuales, factible desde un punto de vista ejecutivo en los hospitales públicos, lo que nos indica que las prácticas así denominadas...

Approved for public release; distribution is unlimited; All organizations, both private and public, must improve, streamline, and automate their business practices to adjust to rigorous demands of a highly volatile marketplace, austere financial resources, and manpower reductions. This thesis analyzes the potential of business process reengineering (BPR) to dramatically improve the Military Pay Document Process (MPDP) for the United States Army and the United States Coast Guard financial communities. Based on Nissen's methodology the MPDP is analyzed and three redesign alternatives are developed, which are capable of yielding order of magnitude improvements in cycle time and cost. This thesis includes process simulation and intelligent systems analysis of the Army and Coast Guard's baseline MPDP to generate and evaluate the three redesign alternatives. Simulation runs demonstrate that cycle time and cost can be reduced substantially by redesigning the MPDP. The redesign alternatives take a comprehensive look at transformation enablers and information technology (IT) capable of eliminating the Personnel Administrative Clerks (PAC) and the finance office functions as they pertain to pay transaction processing. The research concludes that the Army and Coast Guard's MPDP can be dramatically improved by eliminating middlemen functions (PAC and finance office) and shortening the value chain using IT along with other transformation enablers; http://www.archive.org/details/fundamentalrethi00zell; Captain...

Approved for public release; distribution is unlimited; As the defense establishment downsizes, it has turned to the private sector to model its methods for improved productivity. Business Process Reengineering (BPR) is a technique used by the private sector to achieve order of magnitude improvements in organizational performance by leveraging information technology to enable the holistic redesign of business processes. This thesis provides a guide to the methods and tools used during BPR, and presents a practical way for Marine Corps' leaders to establish and direct a reengineering effort. Instruction is provided on the basics of how to establish a strategic direction, organize the reengineering team, and analyze business processes through the use of process-maps, flowcharts, Integrated Definition for Function (IDEFO) models, Activity-Based Costing (ABC), and value-added assessment. Approaches and principles useful during the development of the new process are discussed, as well as benchmarking and the factors leading to process implementation and organizational change. Recommendations are made for further reading; http://archive.org/details/businessprocessr00brew; Captain, United States Marine Corps

Approved for public release; distribution is unlimited.; This thesis reports the results of a business activity modeling exercise to explore how a functional manager in DoD can best improve and redesign one's business processes. The validity of exercise results was assessed and found to be generally accurate with minor modifications. The business activity model was constructed by a faculty/student team in August of 1992, in support of DoD's Corporate Information Management (CIM) initiative. This team used an Integrated Definitions Language (IDEFO) supported software tool (Design/ IDEF by Meta Software of Cambridge, Massachusetts) to construct their model.; Lieutenant Commander, United States Navy

Approved for public release, distribution is unlimited; The purpose of this thesis is to evaluate current Class VIII supply chain procedures at a U.S. Medical Logistics Company (Med Log Co), process map the "as is" baseline process and propose possible "to be" process redesign alternatives that will possibly improve efficiency and produce long-term cost savings. To perform this analysis, the 1st Med Log Co at Camp Pendleton, CA was chosen. The assessment of their "as is" process includes a historical background on medical logistics within the Department of Defense, a comprehensive material logistics literature review, site visits, personnel interviews, process mapping of the baseline "as is" process, and proposal of two redesign alternatives for the "to be" process. A comprehensive analysis was conducted using Thomas Davenport's Process Innovation Framework and quantitative measurements were obtained using the Knowledge-based Organizational Process Redesign (KOPeR) methodology to diagnosis existing pathologies. KOPeR measurements indicate that the 1st Med Log Co's existing "as is" process is a fragmented, mostly manual procurement process that can be innovated now using information technology as a process enabler. Our results indicate that by formally injecting the use of electronic mail and shared databases into the "as is" procurement process an immediate impact can be realized. Further efficiency and cost savings can be accomplished by coupling the injection of information technology with a web- based end-to-end procurement process that assigns a case manager to the "to be" process.; http://www.archive.org/details/towardjointmedic00augu; Major...

Approved for public release; distribution is unlimited; The Norwegian Navy Materiel Command must keep inventory in order to serve its customers. Service level is established as a measure of effectiveness on delivery from inventory. Long replenishment lead-time, with variability in both lead-time itself and lead-time demand, make it hard to achieve the desired service level. The lead-time becomes costly, both in form of holding cost of safety stock and in form of stock-outs. Current inventory control policy used at the Materiel Command is presented, and compared to theoretical inventory control models. Computer simulation is used to measure current administrative lead-time at the Norwegian Navy Materiel Command. Two proposals for redesign of existing replenishment process are built as simulation models, and the effect on administrative lead-time and associated variability is measured. The first proposal is to consolidate two separate procurement offices into one. The second proposal is to introduce, and use electronic commerce in the replenishment process. It is concluded that both redesign proposals will reduce administrative lead-time, variability and hence cost. Benefits from an introduction of electronic commerce will yield a yearly cost saving of at least 4...

Approved for public release; distribution is unlimited.; This thesis describes the development of a database to support business process redesign in the Department of Defense (DOD). Business process redesign is rapidly becoming an important part of DOD's Corporate Information Management (CIM) initiatives. DOD is changing the way it does business in order to meet its commitments with fewer resources. In describing the development of a database to support business process redesign, this thesis reveals insights into the methods and practices that are changing the way business is practiced. The challenge encountered in this project is the process of business process redesign in DOD is being developed concurrently with the database. In effect, the database is built to support a process that is itself not fully understood. It was found that sufficient information on business process redesign existed and could be quantified in such a manner as to be made available in database format. The development of a prototype database progressed to a stage where it could be implemented. The next step is to build a fully functional model of the database in order to evaluate its role in supporting business process redesign.; Lieutenant, United States Navy

Approved for public release, distribution is unlimited; Past studies show that significant positive results can be reaped if a 2-sided matching algorithm is used in the Navy enlisted distribution process. This includes ensuring that commands get the quality of sailors that they demand while satisfying sailors' preferences of their next billet, and thereby improving their motivation and propensity to reenlist. Past studies have also examined the current process in the Navy and detailed its shortcomings. Other research has also detailed the possible uses of optimization technology, smart agent technology, employee-to-job matching algorithms, incentive driven assignments and other technologies to improve on employee-job assignments in large hierarchical internal labor markets, like those found in the military. It is also noted that there are constraints within the military that can pose challenges to the direct application of these technologies to improve the process. These constraints can be structural, behavioral, political, and cultural. To improve the current process, both the available technologies and constraints need to be reexamined holistically and the technologies and current personnel policies modified to meet these needs. This study looks at these issues and proposes an alternative design of the Navy enlisted distribution process that will yield quantum gains for the Navy and its sailors. It details the key operational and user specifications required of a prototype Navy enlisted distribution decision support system.; Major...

An important quality aspect of official statistics produced by national statistical institutes is comparability over time. To maintain uninterrupted time series, surveys conducted by national statistical institutes are often kept unchanged as long as possible. To improve the quality or efficiency of a survey process, however, it remains inevitable to adjust methods or redesign this process from time to time. Adjustments in the survey process generally affect survey characteristics such as response bias and therefore have a systematic effect on the parameter estimates of a sample survey. Therefore, it is important that the effects of a survey redesign on the estimated series are explained and quantified. In this paper a structural time series model is applied to estimate discontinuities in series of the Dutch survey on social participation and environmental consciousness due to a redesign of the underlying survey process.; Comment: Published in at http://dx.doi.org/10.1214/09-AOAS305 the Annals of Applied Statistics (http://www.imstat.org/aoas/) by the Institute of Mathematical Statistics (http://www.imstat.org)

Post-print; Many aerospace companies are currently making the transition to providing fully-integrated product-service offerings in which their products are designed from the outset with life-cycle considerations in mind. Based on a case study at Rolls-Royce, Civil Aerospace, this paper demonstrates how an interactive approach to process simulation can be used to support the redesign of existing design processes in order to incorporate life-cycle engineering (LCE) considerations. The case study provides insights into the problems of redesigning the conceptual stages of a complex, concurrent engineering design process and the practical value of process simulation as a tool to support the specification of process changes in the context of engineering design. The paper also illustrates how development of a simulation model can provide significant benefit to companies through the understanding of process behaviour that is gained through validating the behaviour of the model using different design and iteration scenarios.; This research was co-funded by the Technology Strategy Board?s Collaborative Research and Development programme (www.innovateuk.org), reference TP/2/IC/6/I/10292, and the IMRC Block Grant. We are also indebted to Dr. Michael Moss and all the other personnel within Rolls-Royce who supported this research.

International Design Conference - DESIGN 2010; Future design environments will necessitate improved management of the propagation and impacts of changes. To ascertain whether change prediction can assist in making better work prioritisation decisions, this paper develops a new simulation approach and applies it to a model of a complex aerospace product, which was elicited from industry. We use an accepted technique to generate potential change propagation trees and apply Monte Carlo methods to generate a sample space within which multiple scheduling policies could be evaluated and compared. The experiments reveal that poor coordination of change activity can result in significant process inefficiencies, that the potential for inefficiency increases for larger change networks, and that a modest ability to accurately predict change propagation in the specific case at hand could have a dramatic effect in reducing unnecessary rework. The experiments also suggest that the capability of predicting multiple steps of change propagation would provide only minimal additional improvement.

The performance of product development processes is important to the commercial success of new products. The improvement of these processes is thus a strategic imperative for many engineering companies ? the aero-engine is one example of a complex product for which market pressures necessitate ever-shorter development times. This thesis argues that process modelling and simulation can support the improvement of complex product development processes. A literature review identified that design process modelling is a well-established research area encompassing a diverse range of approaches. However, most existing tools and methods are not widely applied in industry. An extended case study was therefore conducted to explore the pragmatic utility of process modelling and simulation. It is argued that iteration is a key driver of design process behaviour which cannot be fully reflected in a mechanistic model. Understanding iteration can help select an appropriate representation for a given process domain and modelling objective. A model-based approach to improve the management of iterative design processes was developed. This approach shows that design process simulation models can support practice despite their limited fidelity. The modelling and simulation framework resulting from this work was enhanced for application to a wider range of process improvement activities. A robust and extensible software platform was also developed. The framework and software tool have made significant contribution to research projects investigating process redesign...

In industry the key to excellent products is continual process improvement. Although process improvement is a timely procedure, results can be actualized through quality management and engineering concepts. This paper will analyze the production start-up of a copier frame and will further utilize process improvement strategies to improve the production process. The improvement strategies will include frame redesign, avoidance of material warpage due to welding, total quality management, as well as statistical process control guidelines. The frame redesign will look at eliminating unnecessary piece parts and reducing the overall production time and cost of the frame. This analysis will be conducted with the aid of Boothroyd and Dewhurst's (BDI) Design for Assembly (DFA) software. Next finite element analysis (FEA) and heat transfer techniques will be utilized to examine the warpage that the frames experience from welding. Algor SuperSap will be the software package utilized for the FEA. Finally, total quality management (TQM) and statistical process control (SQC) procedures will be examined. The best practices for this application have been implemented or will be recommended for future implementation.
