Scenarios are widely used to specify the behavior of software due to their informality and accessibility. However, their informality makes them difficult to analyze and manage. We address these difficulties with two complementary approaches, one syntactic and one semantic, that add a small amount of structure to scenarios to allow automated analyses and support. The syntactic approach represents a scenario as a set of attribute-value pairs, some of which may also be viewed as events, each of which is an actor-action pair, that are arranged in a sequence. This representation supports the use of episodes (shared subsequences of events) to show dependency relationships between scenarios and to help maintain those relationships as the scenarios evolve. The representation also supports automated measures of similarity between scenarios, to find duplicates or near-duplicates, searching in a collection of scenarios, and assess requirements coverage and completeness of the collection. The representation can be analyzed for consistency of various attributes within individual scenarios. The semantic approach integrates the scenarios that describe a system into a network that expresses which scenarios can follow each other. The network expresses the context expected by the events of each scenario and the temporal relationships between the scenarios. This information is either implicit or incomplete for an ordinary collection of scenarios. Construction of a scenario network provides process guidance for assessing and improving completeness and consistency of the scenario collection. A scenario network represents equivalence relationships between scenarios, and these relationships can be used to organize and classify the scenarios and to maintain the temporal relationships between scenarios as the scenarios evolve. A scenario network can be analyzed to evaluate completeness of the scenario collection and several kinds of consistency between scenarios in the collection. Together.

We have described the development of a new micro-payment system, NetPay, f- turing different ways of managing electronic money, or e-coins. NetPay provides an off-line, anonymous protocol that supports high-volume, low-cost electronic trans- tions over the Internet. We developed three kinds of e-wallets to manage coins in a NetPay-based system: a sever-side e-wallet allowing multiple computer access to- coins; a client-side e-wallet allowing customer PC management of the e-coins, and a cookie-based e-wallet cache to improve performance of the client-side e-wallet c- munication overhead. Experiences to date with NetPay prototypes have demonstrated it provides an effective micro-payment strategy and customers welcome the ability to manage their electronic coins in different ways.

Collaborative Networked Organizations represent one of the most relevant organizational paradigms in industry and services. A large number of developments in recent years have turned Collaborative Networks into a pervasive phenomenon in all socio-economic sectors. The main aim of this book is to provide a comprehensive set of reference materials derived from the results of the ECOLEAD project in one organized volume. The ECOLEAD project, a large 4-year European initiative, involved 28 organizations (from academia, research and industry), from 14 countries (in Europe and Latin America). Three main types of results from ECOLEAD are presented: (i) Conceptual frameworks and models, (ii) Methods and processes, and (iii) Software tools and systems. Furthermore, the experience and lessons learned with a number of large pilot implementations in real-world running networks of enterprises are also included as an indication of the assessment/validation of the project results. Methods and Tools for Collaborative Networked Organizations provides valuable elements for researchers and practitioners involved in the design, implementation, and management of collaborative forms in industry and services.
