With the advent of modern wireless communication techniques, mobile devices play an increasingly important role in our daily life. Users often use these mobile devices to record and retrieve information about tasks and data. In fact, many of people¡¦s daily activities are not independent, and they are likely to be process-oriented. Previous work reported in [Chen01] used metagraph to model user¡¦s activities and proposed a client-server architecture of personal workflow system for supporting pervasive computing. This architecture allowed users to define their personal processes and provided a set of operations for manipulating them. However, the proposed system is passive in that it did not provide any support to help mobile users construct their personal processes, nor did it provide friendly query interface for users. Our work aims at constructing a personalized workflow template provider and providing a user-friendly interface design. The personalized workflow template provider intends to provide personalized workflow templates of organization-driven processes. Users with different backgrounds and interests may retrieve different personal workflow template to accomplishing the same goal. In client side, we provide five pre-defined queries for mobile user can efficiently inquire a personal process and design a better interface for a mobile user to browse his/her personal processes. At last, we implemented these two components and evaluate the effectiveness of the proposed design strategies.

O principal problema das atividades baseadas em processos é que não se tem controle total das atividades que devem ser executadas. Além disso, não se têm uma visão de quais informações estão sendo manipuladas por essas atividades em um dado instante e nem que as manipula. As técnicas de modelagem de Workflow devem ter como objetivo básico minimizar estes problemas. O objetivo básico deste trabalho consiste no desenvolvimento de um protótipo de um Workflow, utilizando agentes móveis para validar o modelo que será proposto construindo um protótipo de um Workflow que valide na prática os conceitos de agentes móveis e Workflow.

Abstract In the turbulent time, an enterprise facing global competition must rapidly respond to change and sustain competitive advantage for survival. Workflow systems is a technology, which has the function of coordination, communication, and collaboration, to improve productivity and response time. However, the implementation of workflow systems needs much investment, but usually results in much gap between expectations and actual benefits. Therefore, it is an important issue to study the implementation of workflow system to assure the results of such investment. This research explores the influencing factors of implementing workflow systems from the organizational perspective (technology, task, people, and structure) and the process (initiation, adoption, and usage). In general, this study tries to answer the following questions: (1) What factors enable a company to initiate a workflow system? (2) What factors influence a company to adopt a workflow system? (3) What factors affect a company to use a workflow system? Based on the literature concerning implementing information system, groupware, and workflow system, this research induces the model of implementing workflow systems. After confirming this model by using case study method, this research proposes the reference model of implementing workflow systems. At the initiation phase, this research finds eight influencing factors: IT infrastructure suitable for workflow systems, human power of developing workflow systems, clear workflows, achievable objectives, top manager¡¦s knowledge and interest, user involvement in selection, size, and incentives system. At the adoption phase, six influencing factors are identified: adequate workflow systems, redesigning workflows, top manager¡¦s support, user involvement in system development, education of all users, and formalization. At the usage phase, we find six influencing factors: realized objectives, technology support, incremental implementation, top manager¡¦s usage, all users¡¦ usage, and corporate policy.
