Explain the life cycle of an information systems. Apply the steps of the life cycle to the scenario listed below: Imagine that you run a photography printing store. Your employees have been using punch cards for time entry since you started the business. This has led to many problems, including lost cards, inaccurate hours, and employees punching in other employees. Because of these problems, you are considering implementing a computerized time entry system. Describe each step of the life cycle and apply it to your problem in your business.

The development and implementation of an information system involve a structured process known as the system development life cycle (SDLC). This framework guides the systematic planning, analysis, design, implementation, and maintenance of information systems to meet organizational needs efficiently and effectively. Applying the SDLC to a scenario can illustrate how each phase addresses specific problems and goals within a business context.

1. Planning Phase

The first step in the SDLC involves identifying the problem and determining the scope of the new system. In the given scenario, the primary issue is the inaccuracy and inefficiency of employee time tracking using punch cards. The planning phase would include analyzing current processes, understanding the extent of errors due to lost or mishandled punch cards, and assessing the need for a computerized system to improve accuracy and accountability. Objectives such as reducing time theft, improving record accuracy, and streamlining payroll processing are established. This phase also involves feasibility analysis, considering the costs and benefits of developing or purchasing a new system.

2. Analysis Phase

Once the problem is defined, the analysis phase involves gathering detailed requirements from stakeholders, such as employees, managers, and HR personnel. This includes understanding the current workflow and identifying features needed in the new system, like biometric authentication or electronic time stamps. For the business scenario, this phase would also involve studying existing issues with punch cards, such as lost cards, duplicate punching, or misrecorded hours. Requirements for report generation, data security, and integration with payroll are documented to ensure the new system aligns with the organization's needs.

3. Design Phase

During the design phase, technical specifications for the new computerized time entry system are developed. This includes designing user interfaces, selecting hardware (such as biometric scanners or proximity card readers), and defining database structures to store employee timesheets. Security measures, such as login credentials, are incorporated to prevent fraud and unauthorized access. For the photography printing store, this could mean creating an intuitive system interface, ensuring quick clock-ins/outs, and integrating with existing payroll systems. The goal is to produce detailed design documents that guide system development.

4. Development and Implementation Phase

In this phase, the system is built according to the design specifications. Developers create software applications, hardware is procured and installed, and initial testing is performed. Once the system is ready, it is rolled out to employees with training sessions to ensure proper usage. The implementation might involve phasing in the new system gradually to minimize disruption. In the business scenario, replacing punch cards with a digital clock-in system—potentially using biometric fingerprint scanners or electronic badge readers—would be the core activity. Proper testing ensures that the system accurately records hours and securely prevents manipulation.

5. Support and Maintenance Phase

After implementation, ongoing support and maintenance are crucial to ensure the system functions correctly over time. Monitoring for issues, performing regular updates, and gathering user feedback help improve system performance. For instance, if employees encounter difficulties or if discrepancies are observed, adjustments may be necessary. Periodic data backups and security audits also safeguard against data loss or breaches. Over the long term, this phase ensures the system remains aligned with the store’s operational needs, helping to eliminate previous problems related to manual punching and record inaccuracies.

Conclusion

Applying the SDLC to a small business scenario like a photography printing store demonstrates the methodical approach needed to develop effective information systems. Addressing employee time tracking issues through each phase—from planning to maintenance—can significantly improve accuracy, accountability, and operational efficiency. Transitioning from manual punch cards to a computerized system exemplifies how structured system development enhances business processes and minimizes errors. Ultimately, adhering to the SDLC ensures that the new system is reliable, secure, and tailored to the specific needs of the organization.
