Abstract
The purpose of this paper is to find a better B2C environment through collecting what information and supporting interfaces are provided on current B2C web sites. We build a checklist based on the framework of B2C consumer behavior model and used it to evaluate current B2C web sites among three categories: purchasing process, types of products, and the source of web sites. The results indicated that poor information or supporting interface design was provided on web sites during the “evaluating and comparing” process. More information or supporting interface design was provided on the internet bookstore, less information or supporting interface design was provided on web sites that sell tickets and flowers. The local web sites provided more information or supporting interface design than international web sites. The results also showed that the difference is highly significant.

Abstract
Purpose
This paper sets out to present a reappraisal on advanced planning and scheduling (APS) systems in industrial settings and propose an effective approach for APS implementation.
Design/methodology/approach
A case study approach is adopted, and a research framework comprising human‐, technological‐, and organizational‐dimensions is developed to analyze the evidence database which includes business flows, system design documents, archival records, post‐system assessment, participant‐observation and semi‐structured interviews.
Findings
The findings indicate that real‐world production planning problems are ill‐defined, complex and dynamic. A post‐implementation evaluation reveals major pitfalls in the technology‐dominant approach, whose negative ramifications are usually overlooked. Besides, these APS implementation pitfalls are found to be attributable to the real‐world context, human factors and organizational aspects.
Research limitations/implications
Despite advances in information technology (IT) and computer modeling techniques, humans still play critical roles in the production‐planning processes – especially in a complex and dynamic manufacturing environment where incomplete, ambiguous, inconsistent and untimely data make automatic planning unrealistic. A rational human‐computer collaboration scheme under an effective organizational structure would be in a better position to take advantage of the IT.
Originality/value
This paper presents a humans‐technology‐organization‐framework of real planning systems, which is employed to analyze a case of APS implementation. Practical insights are extracted as a result of this field research, and a realist approach is proposed to cope with the problems and pitfalls of APS implementation in industrial settings.

Abstract
Purpose
The primary purpose of this paper is to present an integrated framework for user interface prototyping and evaluation for the development of information systems and to present architecture for evaluating generic applications.
Design/methodology/approach
The framework is constructed through combining two distinctive methods of prototyping and evaluation, statechart and goals, operators, methods, and selection rules. Relevant methods and architectures of the integrated framework are presented in unified modeling language when possible.
Findings
The importance of the usability of information systems is highlighted in this research. However, it still lacks an integrated framework for information system development and usability evaluation. This paper provides a framework that evaluation method is intertwined with user interface prototyping to shorten the time of development lifecycle. The architecture for evaluating generic applications is also invaluable for motion and time study and the procurement of vender‐provided systems.
Research limitations/implications
The user base of information systems is diverse and the requirements of these systems change over time. This paper provides a framework that helps managers and engineers smooth and shorten the development phases. For future works, an object‐oriented programming framework and a tool for evaluating generic applications will be developed.
Originality/value
This paper proposes a comprehensive framework for combining prototyping and evaluation, as well as architecture for the evaluation of generic applications. It shortens the development phases by using formal modeling for user interface construction and evaluation. It also provides means to evaluate candidate systems whose program logics cannot be accessed and modified. It also complements the models used in the framework by extending their practical and academic values.
