    The purposes of this project are to identify the characteristics of local government Enterprise Information Portal (EIP), review the various methods use in capturing the requirement, and define a requirement model for local government Enterprise Information Portal. A requirement model is important as it serves as a good starting point for system developers to understand users' requirement, and it saves time, resources, and cost, reduces risk, improves effectiveness and efficiency and reduces ambiguity. The study focuses on two local governments portals for the purpose of requirement capture. The local governments' portals chose are Subang Jaya Municipal Council (MPSJ) portal, and Ampang Jaya Municipal Council (MPAJ) portal. Besides that Kota Star Municipal Council (MPKS) also becomes the fields of study to capture the users' requirements. The requirements captured from the MPSJ and MPAJ portals and requirements from MPKS are analysed and combined together to produce the requirements for local government in general. However due to time constraint this study only focuses on public user requirements. The requirements captured from the study are modeled out using Unified Modeling Language's UML notation. The models are use case packages, use case diagrams, and use case specification. Besides that systems architecture is also included. The prototyping technique is used to validate the requirements. In this technique, a simple prototype is developed by using PHP scripting language, MySQL Database server, Apache Web Server, and Macromedia Dreamweaver MX for interface. The portal system was validated using system requirements testing and Neilsen's Heuristic Evaluation method. It was concluded that, users requirements were met and the prototype system was operating well, however the functionality and interface of the prototypes were recommended for further improvement. This project concludes by discussing problems and limitations that were encountered in completing this project, and offers a few recommendations for future development in this subject

    Assessing the Fit Between Child Welfare Information Systems and Frontline Workers: Development of a Task-Technology Fit Instrument

    States and the federal government continue to invest heavily in child welfare information systems (CWIS) to improve caseworkers\u27 performance, but the extent to which these systems meet caseworkers\u27 needs is unclear. In the field of child welfare there are no reliable user-evaluation measures states can use to assess the degree to which a CWIS meets caseworkers\u27 needs, and identify which specific features of the CWIS most need improvement. The study developed such a measure based on the task-technology fit (TTF) framework, which posits that users will evaluate the usefulness of a technology based on how well it meets their tasks needs and individual abilities. Concept mapping with caseworkers was used to produce an initial pool of 100 items and 10 dimensions that measure various facets of TTF, which is the central construct of the TTF framework. The items and dimensions were refined with survey responses from 240 caseworkers based on factor analysis and psychometric testing, which yielded a 4-factor TTF construct related to Case Tracking and Prioritizing, IT Support, CWIS Training, and Data Capture and Control. Structural equation modeling was used to test the propositions suggested by the TIT framework, namely that individual, task, and technology characteristics impact user evaluations of TTF, and that TTF impacts individual performance. There was mixed support for the hypotheses in the TTF framework: Workers with more experience on the CWIS gave significantly higher evaluations on all four TTF dimensions. Workers who viewed the CWIS as more compatible with their work style (Work Compatibility) gave significantly higher evaluations on Data Capture and Control. Higher evaluations on Case Tracking and Support was positively and significantly related to Individual Performance. No support was found for the relationship between Task Characteristics, worker type, and urban/rural setting on any TTF dimension. The analysis found support for an unanticipated positive and direct relationship between Work Compatibility and Individual Performance, such that workers who viewed the CWIS as more compatible with their work style reported greater levels of Individual Performance. Work Compatibility explained most of the variance in Individual Performance, and suppressed the effect of other variables in the TTF framework

    Using school performance feedback: perceptions of primary school principals

    Get PDF
    The present study focuses on the perception of primary school principals of school performance feedback (SPF) and of the actual use of this information. This study is part of a larger project which aims to develop a new school performance feedback system (SPFS). The study builds on an eclectic framework that integrates the literature on SPFSs. Through in-depth interviews with 16 school principals, 4 clusters of factors influencing school feedback use were identified: context, school and user, SPFS, and support. This study refines the description of feedback use in terms of phases and types of use and effects on school improvement. Although school performance feedback can be seen as an important instrument for school improvement, no systematic use of feedback by school principals was observed. This was partly explained by a lack of skills, time, and support

    Quality measures for ETL processes: from goals to implementation

    Get PDF
    Extraction transformation loading (ETL) processes play an increasingly important role for the support of modern business operations. These business processes are centred around artifacts with high variability and diverse lifecycles, which correspond to key business entities. The apparent complexity of these activities has been examined through the prism of business process management, mainly focusing on functional requirements and performance optimization. However, the quality dimension has not yet been thoroughly investigated, and there is a need for a more human-centric approach to bring them closer to business-users requirements. In this paper, we take a first step towards this direction by defining a sound model for ETL process quality characteristics and quantitative measures for each characteristic, based on existing literature. Our model shows dependencies among quality characteristics and can provide the basis for subsequent analysis using goal modeling techniques. We showcase the use of goal modeling for ETL process design through a use case, where we employ the use of a goal model that includes quantitative components (i.e., indicators) for evaluation and analysis of alternative design decisions.Peer ReviewedPostprint (author's final draft

    Suggestion systems: a usability-based evaluation model

    Get PDF
    Usability has been used to design and assess products and websites. This paper takes the concept of usability one step further and proposes a framework to assess suggestion systems. Thus taking the concept of usability one step further and applying it in the area of ideas management through suggestion system. The fundamental premise of the article is that a suggestion system designed, with usability in mind, will improve innovation among employees, and hence increase participation. This framework was then used to assess four suggestion systems in an oil and gas company in the middle-east. These systems were further assessed for employee perception of their usability and participation. After collecting data on these three different aspects conclusions are drawn. Out of the four systems analyzed, the most usable suggestion system had the highest participation rate and the least usable system attracted the fewest suggestions

    Cloud Computing has generated considerable interest in both companies specialized in Information and Communication Technology and business context in general. The Sourcing Capability Maturity Model for service (e-SCM) is a capability model for offshore outsourcing services between clients and providers that offers appropriate strategies to enhance Cloud Computing implementation. It intends to achieve the required quality of service and develop an effective working relationship between clients and providers. Moreover, quality evaluation framework is a framework to control the quality of any product and/or process. It offers a tool support that can generate software artifacts to manage any type of product and service efficiently and effectively. Thus, the aim of this paper was to make this framework and tool support available to manage Cloud Computing service quality between clients and providers by means of e-SCM.Ministerio de Ciencia e InnovaciĂłn TIN2013-46928-C3-3-RJunta de AndalucĂ­a TIC-578
