  1. 1. An E-DSS for Strategic Planning of E-Commerce Website Development Ranjit Bose Associate Professor of MIS Anderson School of Management University of New Mexico Albuquerque, NM 87131 USA E-mail: ABSTRACT help the information technology managers and professionals who are considering In this new millennium, entirely new construction of such a DSS for their markets, products, and services are organization. emerging from digital technologies such as Internet based businesses or e-commerce. Strategic planning of e-commerce website development is one of the critical activities of 1. INTRODUCTION an organization within the context of its e- commerce investment and success. The Today’s e-commerce environment is unstructured nature of this problem-solving increasingly becoming complex, the focus is activity makes it an appropriate candidate towards using “The Web” and its enabling for decision support systems (DSS) based technologies to strategically create a web solution design. In this paper, we propose presence or website that can provide value- the development of such a DSS, which we added capabilities and integration in all call an e-DSS, since it is Internet based. The aspects of a business’s functional and purpose of this research is to analyze the operational areas. More businesses are requirements for creating the e-DSS. The moving toward these electronic processes research findings are organized and and procedures that use e-commerce, presented as detailed requirements and pushing the rest of the businesses to take content assessment of each of the e-DSS action or be “e-lagers,” that is, left behind. components, which include the user For example, Lai and Yang (2000) predict interface, model base and database.

The e-DSS would be able to “only about half of small businesses even provide alternative strategies, as well as have Internet access. Of those, only a small facilities to analyze and evaluate these percentage has continuous Internet access. strategies for selecting the best strategy for To really open up this market, you have to an organization for its e-commerce website get people to understand that the Internet is development. The implications of such a something that can be useful to their system are, first, the e-DSS would bring business.” together new models, new data as well as information, and expert e-commerce E-commerce can be defined as internal knowledge that many individual and external operations of businesses that are organizations and researchers have performed at high speed and response rate to successfully utilized and are seen as critical satisfy the customers, who expect real time in such development.

One of the critical tasks of groups have been studied and analyzed. the IS departments in organizations is prioritization of the above issues.

In this technology era challenge of e-commerce website organizations are more prone to demand risk, development is to define the Internet innovation risk, and inefficiency risk, the customer prior to establishing an Internet goal would be to use the web to reduce these presence (Kiang, Raghu and Shang, 2000). risks and have a clear risk analysis. “Firstly, how many existing or potential Therefore, at the same time there has to be customers are likely to be Internet users?

It does not following components: (a) the users, (b) the make decisions for the user, nor does it user interface, (c) the model base, and (d) the simply supply reports. database. A brief review of DSS is provided in the next section, which is followed by DSS assist managers in assessing the sections that identify the detailed future impact of current decisions. The requirements and contents of each of the system provides this support by returning above components of the e-DSS results based on “what if?” questions, or respectively. assumptions about future conditions. Through an iterative process, a DSS can provide the following types of information to decision makers: (a) decision objectives or 3. DSS BACKGROUND criteria, (b) decision alternatives or strategies, and (c) consequences of decision Decision support systems (DSS) allow alternatives. In deriving these results, the people at many different levels to process may be either model-oriented or systematically analyze problems before data-oriented. Model-oriented processes making a decision (Turban 2001). In the make comparisons and perform analyses process, these systems extend the range and based on an objective model. The model is a capability of the decision-making process, coordinated set of parameters or conditions increasing its effectiveness. DSS are and their relationships. Models usually are especially useful in supporting semi- derived from analysis of historical data and structured and unstructured problems. DSS trends. Data-oriented processes focus on are very different from traditional responses for specific inquiries and data information systems that are based on fixed analysis. While models deal with sets of logic patterns and are mainly report conditions, data inquiries and data analysis generators. In contrast, DSS are customized are concerned with specific questions. management systems that support non- routine decision-making and evaluation by offering a variety of options to develop various logic methodologies. 4. E-DSS USERS DSS are integrated multi-platform The users of the e-DSS would include system focused on specific decisions that but not limited to the following members: combines corporate data, models, and strategic planners, VP of marketing interactive, user-friendly software into a communications, project leader of web single powerful support system under user development, marketing design team leader, control. DSS occupy a wide band in the technical IS managers, programming leaders, spectrum of data versus model-oriented web server managers, and database systems. DSS are always a combination of administrators. Other decision-makers that both data and models, but one system will might be involved would be project auditors, differ in emphasis from another. The human resource managers, enterprise interactive and user-friendly software in DSS business application leaders who may need is designed to be as easy to use as possible. It large application integration to systems such is geared primarily toward corporate users as Peoplesoft, Oracle Financials, SAP who are not very computer-oriented. The systems, and procurement.

E-DSS USER INTERFACE such as Action Technologies might be integrated with project task applications and Given that the e-DSS itself is Internet vote and ranking process to facilitate the based, the user interface would have to be decision-maker’s progress. Additionally, an very user friendly. The e-DSS would be a EDM system such as WebFileShare, where true example of what a website might “documents in an electronic form are ultimately provide (Conway and Koehler, provided by a single repository (typically a 2000).

In order for the user interface information to decision-makers in a usable to be adaptable, at the level mentioned format, much like an executive information above, it must incorporate collaborative system,” (Turban, 2001).

It captured the critical Larsen and Bloniarz (2000) developed a information from the planner and gave a model called “the cost-performance model,” detailed process of evaluation and use.

E-DSS DATA BASE Much of these data that will be needed by the e-DSS would come from the web itself such The data that will be required for as from web performance logs, from web supporting the strategic planning of e- servers, IP, router information from network commerce website development can be utilities to determine throughput, disk and categorized into three main categories: CPU usage. strategic planning data requirements, marketing data requirements, and IS data Additionally, the e-DSS metadata and requirements.

Lastly, components, IS project development, the e-DSS should be able to store metadata maintenance, computer systems, and on what data was most used by the outsourcing. Additionally, data from vendors organization in the decision-making sessions would also be required. by its different decision-makers. The required marketing data is extensive In order to store and organize these vast compared to the other two categories mainly amounts of data, a data warehouse will be due to the need for continuous data capture necessary. A data warehouse is a related to the customers or target audience. “centralized repository that must support To be able to have a website that focuses and complex decision support queries at high redefines the marketing strategy, it will need performance.

This research analyzed the warehouse,” (Bose and Sugumaran, 1999). requirements for creating the e-DSS. Two of the most important abilities in To construct a successful e-DSS for the warehouse should be OLAP (on-line planning e-commerce website development analytical processing) and data mining, both for an organization, there are several of which allow decision-makers the ability to implementation steps which need to be structure the data for greater analysis and addressed. These steps include: (a) findings that would not be possible evaluating the needs, (b) examining the otherwise. OLAP is a utility that is tightly technology and process capabilities, (c) integrated with a modern RDMS such as assessing the website security requirements, Oracle 8i (Karpain and Myers, 2000). Data and (d) determining the related hardware and mining would use intelligent agents, AI software. The research findings provided the technologies and possibly an expert system specifications for these steps for each of the module that will contain algorithms to e-DSS components, which included the user extract unknown relationships from within interface, model base and database. These the data warehouse, to help the decision- findings should be of immense help to the maker. “The data mining tasks can involve information technology managers and the discovery of association rules, sequential professionals who are considering patterns, pagesview clusters, user clusters or construction of such a DSS for their any other pattern discovery method in a organization. website,” (Mobasher, Cooley and Srivastava, 2000).
