The W Life Cycle Model and Associated Methodology for Corporate Web Site Development

The last few years witnessed the increasing internal and external use of the Internet by organizations. Web sites grew in sophistication from conventional sites composed of a simple collection of Web pages for public relations or marketing to complex Web information systems dealing with business-to-customer transactions or business-to-business networks. However, most organizations still do not have a formal process of Web site development, and corporate Web sites are often developed in an unorganized and uncoordinated fashion. The results of this chaotic situation include slow delivery, conflicting standards, discrepancies with respect to corporate objectives, and redundant development efforts. To help alleviate this situation, this paper presents the W software life cycle model for corporate web site development along with an associated methodology to guide Web development groups in their endeavors. The proposed process model and methodology are based on insights gleaned by studying development projects for three types of corporate Web sites: intranets, Web-presence sites, and transactional sites. However, because Web information systems are more complex, the article also provides recommendations for how the methodology can be adapted to handle these types of applications better

Evaluation of entrepreneurial behavior of technology based companies in stages of the business life cycle

Purpose: The purpose of this paper is to evaluate the entrepreneurial behavior of managers of technology-based companies in specific stages of the business life cycle. Design/methodology: Structured questionnaire based on the entrepreneurial behavior characteristics was applied to the thirty-one managers of the technology-based companies mapped for the paper. The collected data were processed by the Hierarchical Process Analysis (AHP) technique in a multicriterial approach to measure the entrepreneurial behavior according stages of the business life cycle. Findings: The results of the paper show that the level of entrepreneurial behavior of managers follows the development of the company. Managers working in technology-based companies at later stages of the business life cycle showed more entrepreneurial characteristics. The results showed that the experience that the manager acquires as the company evolves influences his or her behavior and consequently the company's performance. Moreover, certain characteristics could be related to the particularities of each stage of the business life cycle. Originality/value: The results of this paper can provide managers with understanding of how entrepreneurial behaviors diversify according to the stage of the technology-based company. Since both entrepreneurial behavior and the stages of the business life cycle influence the performance of technology-based companies, the results provide important knowledge for managers to improve their businesses. These managers can use the contributions of the paper as a management practice throughout the stages of their existence, which may provide the adoption of more appropriate strategies, being a connection between the theory studied and the business practice

Integrated product and process development methodologies for environmentally conscious electronic products

This research focuses on integrated product and process development (IPPD) methodologies for environmentally conscious electronic products. After a review of current research issues in the field of product and process development, a generic framework for IPPD is proposed which describes most of the concerned issues formally as constrained optimization problems. These problems may include such optimization objectives as cost, benefit, and environmental impact. Based on this framework, an IPPD methodology is proposed as a systems approach to competitive and environmentally conscious product and process development. A case study on personal computer development is performed illustrating how to apply the methodology meaningfully and efficiently. Eco-compass concept is then integrated into the methodology to evaluate environmental impact, and a case study on business telephone development is performed. To automate the design of products and processes, a solution methodology for IPPD based on logical representation of process relations is proposed with two illustrating product development examples. Finally, a timed IPPD methodology is introduced with increased modeling capability and decision accuracy. It considers the execution duration of processes and their time-varying characteristics. The timed methodology is applied to the life cycle development of flexible manufacturing systems (FMSs) and provides a new way to develop cost-effective, high-quality, and environmentally conscious FMSs

A new approach to the development and maintenance of industrial sequence logic

This thesis is concerned with sequence logic as found in industrial control systems, with the focus being on process and manufacturing control systems. At its core is the assertion that there is a need for a better approach to the development of industrial sequence logic to satisfy the life-cycle requirements, and that many of the ingredients required to deliver such an approach are now available. The needs are discussed by considering the business case for automation and deficiencies with traditional approaches. A set of requirements is then derived for an integrated development environment to address the business needs throughout the control system life-cycle. The strengths and weaknesses of relevant control system technology and standards are reviewed and their bias towards implementation described. Mathematical models, graphical methods and software tools are then assessed with respect to the requirements for an integrated development environment. A solution to the requirements, called Synect is then introduced. Synect combines a methodology using familiar graphical notations with Petri net modelling supported by a set of software tools. Its key features are justified with reference to the requirements. A set of case studies forms the basis of an evaluation against business needs by comparing the Synect methodology with current approaches. The industrial relevance and exploitation are then briefly described. The thesis ends with a review of the key conclusions along with contributions to knowledge and suggestions for further research

Tourist Destination Integral Product Eco-Efficiency

The main objective of this article is to illustrate the accounting methodology for eco-efficiency measurement, which allows for inclusion of the economically-orientated component in the processes of environmental reporting on tourist destination integral product, while examining the interrelation of eco-costs and values found in the classic LCC and particular tourist destination SBU (Strategic Business Unit). The process of tourist destination integral product eco-efficiency measurement calls for development of environmental accounting methods suitable for presentation of economically-orientated sustainability information. In the complex process of integral product eco-efficiency measurement, LCA (Life Cycle Assessment) and LCC (Life Cycle Costing) take important roles. Interpretation and presentation of the data includes detailed cradle-to-grave environmental impact assessment of direct and indirect tourist activity and different products of tourist destination SBU’s. Eco-costs represent the monetary component in the processes of environmental accounting and reporting on environmental impact of tourist destination integral product

The Implementation of Business Process Blockchain Technology Based of MSCWR SmartBox Model

Blockchain technology uses in many fields, and one of them is logistics. This study aims to propose designing and implementing a blockchain technology-based application for logistics delivery combined with the Internet of Things (IoT) called MSCWR. Logistics and delivery of valuable products have a common problem, and security is also questionable. Therefore, the research process in making prototypes starts by defining the problem, planning, prototyping, testing, and designing validation. The methodology used is User-Centered Design, focus group discussion conducted with business actors directly, and system or prototype development using the System Development Life Cycle framework. As a result, the business processes create using an activity diagram, the features define using a use case diagram, and the screen design to show the prototype development created at an early stage in the research. Finally, the testing conducts to test how well the system is running. In the end, the validation of test results performs in good results &nbsp

An application of hybrid life cycle assessment as a decision support framework for green supply chains

In an effort to achieve sustainable operations, green supply chain management has become an important area for firms to concentrate on due to its inherent involvement with all the processes that provide foundations to successful business. Modelling methodologies of product supply chain environmental assessment are usually guided by the principles of life cycle assessment (LCA). However, a review of the extant literature suggests that LCA techniques suffer from a wide range of limitations that prevent a wider application in real-world contexts; hence, they need to be incorporated within decision support frameworks to aid environmental sustainability strategies. Thus, this paper contributes in understanding and overcoming the dichotomy between LCA model development and the emerging practical implementation to inform carbon emissions mitigation strategies within supply chains. Therefore, the paper provides both theoretical insights and a practical application to inform the process of adopting a decision support framework based on a LCA methodology in a real-world scenario. The supply chain of a product from the steel industry is considered to evaluate its environmental impact and carbon ‘hotspots’. The study helps understanding how operational strategies geared towards environmental sustainability can be informed using knowledge and information generated from supply chain environmental assessments, and for highlighting inherent challenges in this process

Use of Life Cycle Costing to Compare and Assess Business Performance Differences and Opportunities Regarding Traditional Topsides versus Subsea Chemical Storage and Injection for Subsea Wells

As a significant aspect of sustainable development, Equinor is currently engaged in a substantial technology advancement involving subsea all-electric (AE) functions as a replacement for the conventional topside electro-hydraulic (EH) functions. Within the AE function, subsea infrastructure developers are planning and developing a Subsea Chemical Storage and Injection System (SCSIS) on the seafloor infrastructure. The system consists of storage units for chemical products located on the seafloor, connected to the manifold for onwards distribution. It serves as an alternative to the conventional distribution system where chemical products are stored in storage tanks on the topsides facility (e.g. fixed or floating platform) and injected into the subsea production system via an umbilical. The primary objective of this thesis was to conduct an evaluation of the business performance differences between the EH function and the AE function within the domain of chemical injection, over a 20-year design life. To achieve this objective, the thesis employed the life cycle costing methodology as presented in ISO 15663:2021. The methodology served as a comprehensive tool for comparing the life cycle costs of two alternative options. By identifying cost elements and cost drivers for each of the options associated with the main elements of life cycle costing, namely CAPEX, OPEX, and LOSTREV, the life cycle costing methodology could be utilized. Furthermore, by employing a diverse range of economic evaluation measures, coupled with trade-off considerations in life cycle costing such as HSE and sustainability factors, the thesis study aimed to determine which option offered superior benefits. The economic evaluation measures encompassed a variety of Monte Carlo simulations implemented within an Excel model to facilitate probabilistic cost estimations for each of the economic evaluation measures. The model was executed utilizing modified Equinor-specific data that aligned with the technical and operational basis outlined in Chapter 2 of the thesis. These modifications ensured that the data employed in the analysis were tailored to meet the specific requirements and standards established in the theoretical framework of the thesis. The thesis has demonstrated that employing the life cycle costing methodology for a project with a 20-year life cycle yields significant insights that aid in the decision-making process for investments within the petroleum industry. The accuracy of the cost estimations has been substantiated through a comparative analysis conducted on an offshore project of comparable scale, as well as consultation with Equinor representatives. Moreover, the thesis has illustrated that employing a probabilistic estimation methodology, supported by both top-down and bottom-up estimation approaches, can effectively address substantial uncertainties inherent in the life cycle cost analysis, resulting in sound results

Review of Agile Development Ceremonies and Analysis of Its Various 4 Development Stages

Agile methodology is the process in project management or software development which helps the business and organisations to deliver the product faster to the end user with higher performance rate and with great efficiency. Agile development focuses on providing solutions in incremental approach which means that it focuses on converting few requirements into functional software and then give it to the user to provide feedback after which again the same process is repeated to achieve satisfaction from consumer’s side. The advantage of using this approach is that if there are any changes to be made than that can be made easily without much efforts, since it is incremental model. An agile ceremony is an occasion when the team members conduct a meeting to decide on the tasks to be performed once few milestones are achieved. There are four main types of ceremonies of agile development which will be discussed in detail in this paper. The focus of each ceremony of agile is to verify the key achievements made in a project life cycle and to discuss the consistent check points in the cycle. The paper will also discuss the benefits and limitations of agile ceremony software development

Structured identification of business improvement opportunities using Life Cycle Assessment : A case study in the gas turbine industry

Part of: Seliger, Günther (Ed.): Innovative solutions : proceedings / 11th Global Conference on Sustainable Manufacturing, Berlin, Germany, 23rd - 25th September, 2013. - Berlin: Universitätsverlag der TU Berlin, 2013. - ISBN 978-3-7983-2609-5 (online). - http://nbn-resolving.de/urn:nbn:de:kobv:83-opus4-40276. - pp. 205–209.In the last two decades the power sector has been adopting environmental conscious practices in several business areas and processes. Bridging the identification of environmental “hot-spots” in the product life cycle and the implementation and execution of an environmental management system requires an integrated approach starting with a Life Cycle Assessment to identify the improvement potentials; then analyzing the current management and product development systematics in use, and finally mapping the environmental practices against the improvement potential. The improvement tracking will be embedded in the management system as an Environmental Improvement Roadmap, mapping the efforts required to realize the goals. The methodology has been implemented in pilot studies, focusing on the processes performed in-house to enable further decisions on process alternatives and providing reliable information for strategic decisions within the Siemens Environmental Product Portfolio
