Valacich Pages: Analysts use RFPs as a way to get vendors to perform the research to determine what application design will meet user requirements and the hardware and systems software vendors believe are necessary for developing the new system.
To verify vendor claims about a software package, an analyst can ask for a software demonstration, use the software and its documentation and training materials personally, talk with other users of the software, and consult independent software testing and abstracting services surveys available for a fee.
Enterprise resource planning systems consist of a series of integrated modules; these modules pertain to specific, traditional business functions. However, these modules are integrated to focus on business processes rather than on business functional areas. Possible disadvantages of this approach include complexity, lengthy implementation, lack of in-house expertise, expense, and changing how the organization conducts its business. These projects when accomplished successfully are most often approached as an institutional change project, not simply an IT project.
Reuse is most often applied to object-oriented and component-based development.
Creating, storing, and maintaining objects and components that can be drawn on again and again for new applications. Reuse should in theory increase programmer productivity, decrease development time, minimize errors, and schedule overruns. Ultimately it should produce higher quality work with. In current practice, due to high initial startup costs, lack of good quality methods for labeling, storage, combined with lack of senior management commitment, reuse is not practiced as often as it could be.
Additionally, lack of incentives and rewards to design for and apply reuse concepts and the overall difficulty in measuring economic gain from its application all conspire against reuse in the real world.
Note Figure on the high initial startup costs when a high level of reuse is planned. As more organizations achieve success and as more componentization takes place in the for purchase arena more organizations will have incentive to integrate reuse into their business strategy. In comparing and contrasting the four approaches to reuse, the student should note the advantages and disadvantages listed in Table Note also that no one type yields the best possible solution.
Answers to Problems and Exercises 1. An organization uses the Request for Proposal RFP to solicit proposals from several competing vendors. Usually, RFPs first provide background information on the company and the business units involved in the request, an explanation of the information systems needs, a description of what is wanted from the vendors i. The bulk of the document then describes the mandatory, essential, and desirable requirements in the areas of need e.
To a certain extent this is functional. On the other hand, this can be dysfunctional. Eventually, software will evolve and the market will change, and the employees and the company will be left behind using antiquated technology. Additional criteria include compatibility with currently used application software so, for example, data can be shared , compatibility with existing hardware and system software, ability to support a range from novice to experienced or power users, and appeal of the user interface ease of use.
The list for evaluating alternative custom software developers is similar to that for selecting off-the-shelf application software or for computer hardware and system software.
Such vendors should have an established track record for developing similar software in other organizations.
Their references should be checked thoroughly, including visits to other sites. Vendor capability may change over time. From a legal point of view, you may want to select a custom developer based on the willingness to sign a non-disclosure agreement, so that he is. The project team can use the advantages of the enterprise resource planning design as part of its strategy for selling this system.
The team can stress that this solution consists of a series of integrated modules; these modules are integrated to focus on business processes, and the firm can integrate all parts of a business process. This approach includes a single repository of data, thus providing more consistent and accurate data and less maintenance. These modules are flexible and new modules are easily integrated into an existing system. Also, an enterprise resource planning ERP system might be justified on the following grounds: In both cases, the team may also employ testimonials and reports of results from other organizations that have benefited from the ERP strategy.
Other users can be both a reliable and insightful source of information. Guidelines for Using the Field Exercises 1. Business people are likely to use this list of criteria in some formal or informal way.
Have your students present their findings to the class so that they can learn about a variety of companies. It is useful for students to see how companies actually use these criteria and methods in purchasing offthe-shelf software.
Encourage students to understand why their interviewees prioritized the criterion list in such a manner. Obtaining RFPs may be difficult for your students. It may be necessary for you to obtain copies of RFPs either from business contacts or from the university.
It is very useful for students to see real RFPs. Students are amazed at how lengthy and detailed these are for larger, more complex systems and at how complicated RFPs can become for governmental agencies. Help students understand that government agencies are subject to federal laws that do not always apply to private organizations.
