This paper discusses an document discovery tool based on formal concept analysis. The program allows users to navigate email using a visual lattice metaphor rather than a tree. It implements a virtual file structure over email where files and entire directories can appear in multiple positions. The content and shape of the lattice formed by the conceptual ontology can assist in email discovery. The system described provides more flexibility in retrieving stored emails than what is normally available in email clients. The paper discusses how conceptual ontologies can leverage traditional document retrieval systems.

A complexidade do ambiente em que vivem as organizações nos dias de hoje exige Sistemas de Informações (SIs) eficientes, que sirvam como apoio à tomada de decisão por parte dos gestores, em especial no que diz respeito às questões ligadas à Tecnologia da Informação (TI) diante dos novos paradigmas de gestão enfrentados pelas Pequenas e Médias Empresas (PMEs). Este trabalho tem como objetivo geral a avaliação da percepção dos gestores das PMEs brasileiras, quanto ao impacto do uso da TI como elemento de melhoria dos processos financeiros das organizações. Para que tal objetivo fosse alcançado, foram desenvolvidos e estudados os seguintes objetivos específicos: verificar de que forma a TI é percebida como útil nas pequenas e médias empresas, em especial na automação de rotinas financeiras de tesouraria e fluxo de caixa; verificar se a automação de rotinas financeiras com a utilização da TI subsidia os processos de tomada de decisão em tais empresas e, ainda, verificar se sua utilização é vista como uma vantagem estratégica. Em seu levantamento bibliográfico, este trabalho apresenta conceitos relacionados a Competição, Pequena e Média Empresa, Estratégia e Gestão de Competência. Esses conceitos foram encontrados na literatura e em artigos na imprensa especializada. Na pesquisa empírica realizada, este trabalho procurou, através de estudos de casos múltiplos em 5 empresas, aprofundar as questões relativas à percepção dos gestores em relação à TI utilizada nos procedimentos financeiros implantados nas organizações que dirigem. O planejamento da amostra foi feito de maneira a permitir não só a análise individual de cada respondente como também a análise das organizações onde atuavam. As conclusões a que este estudo chegou são: a) os gestores têm a percepção de que a utilização de TI nas rotinas financeiras e de fluxo de caixa é imprescindível, pois a automação é necessária para a manutenção e a agilização dos processos de relacionamento com clientes e fornecedores; b) a TI pode subsidiar processos de tomada de decisão estruturada, especificamente as decisões que tratam de rotinas financeiras. Outro aspecto que fica claro na percepção dos gestores é que a dependência da empresa aos SIs aumenta com o crescimento da empresa e, conseqüentemente, com o volume de informações com que os gestores têm de lidar; c) na percepção dos gestores, a utilização de TI nos processos financeiros das PMEs é importante, mas eles não são os determinantes da vantagem estratégica da organização. Os estudos permitiram duas outras observações importantes: d) as estruturas organizacionais das empresas estudadas eram pertinentes aos itens de TI que possuíam; e) há diferença de visão entre gestores e subordinados. A conclusão deste estudo, que responde ao objetivo geral, é que, na percepção dos gestores, a TI tem um impacto positivo como elemento de melhoria dos processos financeiros das organizações, porém não é o fator que define a vantagem estratégica das organizações: há outros aspectos que devem ser avaliados, e a construção de sistemas complexos que abrangem outras áreas da organização é necessária.(AU)

This paper introduces responsive systems: systems that are real-time, event-based, or time-dependent. There are a number of trends that are accelerating the adoption of responsive systems: timeliness requirements for business information systems are becoming more prevalent, embedded systems are increasingly integrated into soft real-time command-and-control systems, improved message-oriented middleware is facilitating growth in event-processing applications, and advances in service-oriented and component-based techniques are lowering the costs of developing and deploying responsive applications. The use of responsive systems is illustrated here in two application areas: the defense industry and online gaming. The papers in this special issue of the IBM Systems Journal are then introduced. The paper concludes with a discussion of the key remaining challenges in this area and ideas for further work.

This thesis deals with the problematic of the business systems systemic purpose definition. The definition of the systemic purpose, which is regarded as the utmost expression of the system's purposefulness, is to be achieved by ensuring the participation of all the stakeholders, if possible, who affect or they are affected by the business system's operations. The nature of participation, defined as a process of the stakeholders' perceptual exchanges, is deemed to be problematic in itself due to the influence exerted upon it by organisational power, coercion and false consciousness. The main focus of the thesis then is to make aware and provide the stakeholders with an explicit philosophical pedestal and a set of principles upon which a meta- epistemological framework for the enquiry of the business system's purposeful behaviour is developed. In addition, the thesis focuses on the development of a methodology that can be used by the stakeholders to achieve self-knowledge through the critical and systemic examination of their normative presuppositions, about the business system, at both sociological as well as the psychological levels concurrently and the subsequent development of an organisational intrinsically motivated information system. According to the critical systems philosophy and principles, developed in this thesis, normative presuppositions define the stakeholders' perceptions about the purposeful behaviour of the business system they perceived as having a material, an informational and/or an emacipatory stake (human interest) in. The methodology will provide Information Systems that demonstrably improve coordination of organisational activities by enabling the development and maintenance of a single/multifaceted view of purpose throughout organisations.

Top of pageAbstract This paper deals with the application of critical systems thinking in the domain of organisational learning and knowledge management. Its viewpoint is that deep organisational learning only takes place when the business systems' stakeholders reflect on their actions and thus inquire about their purpose(s) in relation to the business system and the other stakeholders they perceive to exist. This is done by reflecting both on the sources of motivation and/or deception that are contained in their purpose, and also on the sources of collective motivation and/or deception that are contained in the business system's purpose. The development of an organisational information system that captures, manages and institutionalises meaningful information—a knowledge management system—cannot be separated from organisational learning practices, since it should be the result of these very practices. Although Senge's five disciplines provide a useful starting-point in looking at organisational learning, we argue for a critical systems approach, instead of an uncritical Systems Dynamics one that concentrates only on the organisational learning practices. We proceed to outline a methodology called Business Systems Purpose Analysis (BSPA) that offers a participatory structure for team and organisational learning, upon which the stakeholders can take legitimate action that is based on the force of the better argument. In addition, the organisational learning process in BSPA leads to the development of an intrinsically motivated information organisational system that allows for the institutionalisation of the learning process itself in the form of an organisational knowledge management system. This could be a specific application, or something as wide-ranging as an Enterprise Resource Planning (ERP) implementation. Examples of the use of BSPA in two ERP implementations are presented.

The recent global „credit crunch? has brought sharply into focus the need for better understanding of what it takes for organisations to survive. This research seeks to help organisations maintain their „viability? – the ability to maintain a separate existence and survive on their own. Whilst there are a multitude of factors that contribute to organisational viability, information can be viewed as the lifeblood of organisations. This research increases our understanding of how organisations can manage information effectively to help maintain their viability. The viable systems model (VSM) is an established modelling technique that enables the detailed analysis of organisational activity to examine how the structure and functions performed in an organisation contribute to its „viability?. The VSM has been widely applied, in small/large companies, industries and governments. However, whilst the VSM concentrates on the structure and functions necessary for an organisation to be viable, it pays much less attention to information deployment in organisations. Indeed, the VSM is criticised in the literature for being unable to provide much help with detailed information and communication structures and new theories are called for to explore the way people interact and what information they need in the VSM. This research analyses qualitative data collected from four case studies to contribute to our understanding of the role that information plays in organisational viability, making three key contributions to the academic literature. In the information management literature, this research provides new insight into the roles that specific information plays in organisations. In the systems thinking literature, this research extends our understanding of the VSM and builds on its powerful diagnostic capability to provide further criteria to aid in the diagnosis of viable organisations. In the information systems literature, this research develops a framework that can be used to help organisations design more effective information systems.
