Information Systems Development
Business organizations, businesspeople, use information systems to serve the needs of business. Business professionalism and business organizational practices are some of the key factors involved in understanding the business. Also important is the consideration for the future of the business, and to identify the criteria required to make decisions about the design and development of information systems.
Information systems are made up components forming a system, which contains: people, data, procedures, hardware, programs. These components are operating within business contexts.
It is helpful to understand how the role of information systems has evolved in organizations. While organizations want to develop strategic information systems, they probably have arrived at their current information systems as a result of various tactical decisions.
The information systems investment have a legacy of past information systems; they may need to be re-thought in some cases, and there could be a need for creating entirely new information systems.

Project Example: Integrated Bus Management System
Intellia Ltd's proposal to an Auckland-based bus company to build a new bus management system. The managing director of Intellia arranged a meeting with the general manager of a metropolitan bus company. The meeting was sufficient to understand the bus route tendering process, the financial and municipal authority political issues, as well as the general management perspective on the business of managing a bus company. Furthermore an orientation and inspection of the bus companies operations provided further insights into the business, it's current information system and management, as well as it's projected information needs. The managing director then designed a new information system for the bus company and wrote a formal proposal. The proposed new information system integrates legacy software from Fleet Management, Bus Ticketing and Routes and Schedules, with the latest GPS technology.
Data integration of legacy software data formats with the wireless GPS data transmissions from their buses, can be achieved using the innovative concept of digital data transmission using the existing trunk radio network bus drivers traditionally use to communicate with the bus depot.
The proposal submitted by Intellia contains a complete business analysis and systems analysis with detailed costing's and project implementation plan.
