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 lifecycle of an information system (IS) encompasses a series of structured phases that guide the development, implementation, and maintenance of technology solutions within an organization. Understanding these phases is crucial for ensuring that the system effectively addresses business needs, functions efficiently, and evolves over time to meet changing requirements. Applying the IS lifecycle to a real-world scenario—such as transitioning from manual punch cards to a computerized time entry system in a photography printing store—demonstrates the practical utility and importance of each phase in achieving a successful technological upgrade.

1. Planning Phase

The initial step in the IS lifecycle is planning, which involves identifying the problem or opportunity and determining the scope and feasibility of the project. In the scenario of the printing store, the primary problem is the inefficiency and inaccuracies resulting from the manual punch card system. The goal is to develop a computerized time entry system that improves accuracy, security, and ease of use. During this phase, business analysts and stakeholders assess the current process, identify requirements, and evaluate potential solutions. Feasibility studies evaluate technical, operational, and economic factors to ensure that implementing a new system is justifiable and sustainable.

2. Analysis Phase

Following planning, the analysis phase involves gathering detailed requirements and understanding the current environment. For the store, this means documenting how employees clock in and out, noting issues like lost cards, double punching, and time inaccuracies. Stakeholders—such as management and employees—are interviewed to determine features essential for the new system, including biometric verification, digital time stamps, and reporting functionalities. This phase aims to clarify what the new system must accomplish and defines specific specifications to guide development and procurement.

3. Design Phase

In the design phase, technical specifications are translated into a blueprint for building or selecting the system. For the store, this could involve designing the user interface (e.g., touchscreens or biometric terminals), data management protocols, and security measures to prevent fraud. System architects consider hardware requirements, software architecture, and integration with existing payroll systems. Designing processes to ensure reliability and user-friendliness is crucial, as this phase lays the foundation for the system's functionality.

4. Development and Acquisition Phase

Once designs are finalized, the development phase involves creating or acquiring the system. For the store, this might mean purchasing off-the-shelf biometric time clocks or developing custom software. Customization ensures the system aligns with specific needs, such as integration with payroll databases or generating attendance reports. Testing is conducted during this phase to identify and rectify issues before deployment, ensuring the system operates as intended.

5. Implementation Phase

Implementation involves deploying the new system into the business environment. This includes installing hardware, configuring software, and training employees to use the system correctly. In the store scenario, employees would be instructed on how to punch in with biometric verification or digital entry, replacing the manual punch cards. During this period, organizations often conduct pilot tests to troubleshoot unforeseen issues and facilitate user adaptation.

6. Support and Maintenance Phase

After deployment, the system needs ongoing support and maintenance to ensure continued effectiveness. This includes routine updates, troubleshooting technical problems, and making modifications based on user feedback or changing business needs. For the store, regular system audits can prevent fraud, and updates can be installed to improve user experience or security.

Application Summary

Applying each lifecycle step to the photography store illustrates a structured approach to solving operational problems through technology. Starting with recognizing the inefficiencies of punch cards, the store would plan and analyze requirements for a new digital system. Carefully designing and testing the system ensures it addresses issues like lost cards and employee fraud. Proper implementation and ongoing maintenance sustain the system's benefits, leading to more accurate employee time tracking, reduced administrative overhead, and enhanced workplace security.

In conclusion, understanding and applying the lifecycle of an information system ensures that technological solutions are thoughtfully conceived, effectively implemented, and maintained to meet business goals. The scenario exemplifies how systematic planning and execution can transform manual, error-prone processes into efficient, automated operations, ultimately supporting the store’s productivity and growth.
