buy custom Information System essay We now focus on some of the common needs of the enterprise. For all enterprises, there will be a need for monitoring changes, which involves tracking, changes in businesses, people and industries. In the enterprise, there is a need to know about mergers, emerging risks, people moves, and opportunities and the need to build relationships with new prospects, key customers and business partners. There is a need to link with up with the right people, outlook for new business in any economy, collect intelligence, and measure performance. In addition to the above needs, there is also a need to ensure compliance and discover new opportunities from the fast-breaking trades. All these needs vary from one enterprise to the other depending on the size and nature of enterprise and in turn determine the development of information systems (Vasilecas, 2005, p 45). In the development of the information system, the system developers consider a few steps irrespective of the enterprise. The initial step is of the mission development, where missions give the overarching framework for the whole enterprise. The accomplishment of missions by enterprises is by functions and later on refined into database domains. The establishment of all business information systems and database within this enterprise framework makes it work. The second step is the database design, which is built within the enterprise architecture. The basis of database designs is on enterprise-wide data factors, data replicas of concepts, DMBS independent models, and lastly DBMS dependant models. This will ensure total metadata re-use, semantic harmonization, and data interoperability. The following step is prototype generation. Prototypes are usually set in the enterprise architecture and through the generation of these prototypes maximum eforts can be spent on getting a whole set of requirements. Following this step is the specification evolution stage, which is critical as it allows the full set of requirements to be teased out. By using the information system generators, the capability to progress from iteration to the other is straightforward, and one can achieve this in hours. Another major step in the development of the information system is the request for proposals. This refers to a formal specification of what the enterprise desires to implement. The document should have all the prototype and metadata described in the earlier stages (Giachetti, 2010, p.12). The document should show the evolution, methods of development, evaluation methods, and monitoring methods of the development of information systems. In the development of the information system, there is the proposal evaluation. This stage produces an understanding in regards to the implementation procedure, costs, schedules, reviews, and deliverables. The final stages involve the awarding of contracts, contractor management and conformance testing. So what is the later direction of the development of information systems? The future direction of the development of information systems in dependant on the progress of enterprises, their needs, and innovations in regards to elements of information systems. Different enterprises keep changing in terms of their needs as the enterprises grow and these will in turn affect the information system they use in running their businesses. For instance, a sole trader will change a company and will, therefore, have to change the information system it was using. This means that the future direction of development of information systems will grow to accommodate these changes and growing needs of the enterprises. With the growing industries, the enterprises havee many opportunities of expanding the growing demand from the market. In addition, the technology world is rapidly growing, and it is necessary that the enterprises change to contain this change. The software, hardware and other elements of the information system will change with time and the enterprise will need to update these changes in order to ensure efficiency of their services and products. The advancement of these elements of information systems will in turn lead to further development of information systems (Filipe and Cordeiro, 2011, p.63). In the above discussion, we have information on the definition of development of the information system in relation to enterprises. The paper made a research of the tools and methods applicable in the development of the system development, which includes methods and techniques. To understand the development of information systems, the paper gave more information on the types of enterprises and their needs. It is evident from the discussion that the needs of an enterprise vary from one enterprise to the other, which makes them need varied information systems. We have also analysed the steps system developers in the development of information systems. Information system as a field is a wide field, which keeps on growing and changing with time. The more the innovations the more the field of information systems keeps on changing. This makes the enterprises change their information systems with time to meet their growing needs and demands. For example, when a partnership business enterprise increases its number of key customers it will need to acquire new and better elements of information systems to contain the change. Each day researchers are coming up with better elements of information system that will suit the current environment that enterprises operate in and grow. Buy custom Information System essay
