Businesses utilize data, information, and information systems to achieve their strategic objectives. According to Barlow (1990), the deployment of Strategic Information Systems (SIS) should align with business objectives to achieve strategic goals. The coordination and management enabled by Information Systems (IS) is crucial for companies operating globally. However, a lack of experience and resources can pose challenges. Pant and Hsu (1995) state that the success of an integrated business objective depends on the organization's structure, its level of IT experience, and the availability of information resources.

Due to its importance, SIS is becoming a key integration unit in many business applications. This approach to strategy formation has influenced the current forces visible in global markets. SIS has improved company operations in significant ways, capturing and challenging while improving performance and realizing gains on investment. SIS is a practice that tends to regard application regimes such as planning, connecting multiple applications with different access points, and directly to the information system to arrive at consistent economic evaluation of the information system investment (Rockart 1979).

Pant and Hsu (1995) define SIS as "the analysis of a corporation's information and processes using business information models together with the evaluation of risk, current needs and requirements.” In this way, SIS is understood as a critical requirement for corporate data processing and the development of computer-based systems tailored to a company's needs.

Therefore, there is an intertwined relationship between information system function and corporate strategy (Pavri and Ang 1995; Beath and Orlikowski 1994; Porter and Miller 1985). SIS has been widely used as backroom operation in first line support services to deal with day-to-day mundane tasks, leaving office operations to concentrate on strategic planning (Lederer1992). SIS planning begins with the identification of needs followed by strategic implementation that formalizes objectives, priorities, and authorization of information system projects (Pant and Hsu 1995).

For example, Wal-Mart Stores utilize a computerized inventory control system that electronically orders merchandise from suppliers and maintains an orderly warehouse, using the Wal-Mart Satellite Network (WSN) that enables two-way satellite communications between networks (Sheth 1994). The integration of electronics with information systems is also visible in Apple and Hewlett-Packard computers.

Businesses must align their strategic direction with information system applications as a strategy to increase the importance of information technology. Data protection legislation mandates that subjects are provided with extensive information explaining how data will be gathered and processed, as well as the full identity of data controller and purposes of data being collected.

In conclusion, SIS plans must be specific and simple to allow understanding of procedural order of development. Continuous updating and improving of information system applications to align with a company's strategic objectives against its capabilities is required. The application of SIS is critical to a company's future success, and companies that apply IS are expected to record increased turnover ratios due to reduced error per unit levels.
