Information systems are essential in organizations to standardize business transactions, inform management and employees, and provide communication tools. System analysts need to understand the perspectives of all stakeholders impacted by a system. They require strong communication skills and knowledge of both business and technical languages. Key business drivers for information systems today include e-commerce, globalization, and data analytics. The four steps in the system development process are initiation, analysis, design, and implementation, followed by ongoing maintenance.
Systema analysis
- 1. Chapter One
- 2. Why are information systems (IS) essential in organizations?
- 3. Information systems standardize and enforce rules on business transactions, which helps to ensure quality of both service and process. IS informs management of a business' health, mid-level managers of department needs and planning, employees of standard operating procedures, and customers of business services. IS also provides numerous communications tools for all levels of business, both for quicker collaboration and asynchronous discussions.
- 4. Why do systems analysts need to know who the stakeholders are in the organization?
- 5. The system analyst is responsible for understanding the perspectives of everyone who will have some form of interaction with a system, be it ownership, supervision, architects, or programmers, end -users within the company, or customers. Any deployed system that fails to take into consideration the unique needs and perspectives of any one of these groups will, at the very least, require refactoring and, at the worst, end in project failure as one or multiple groups reject the system.
- 6. What kind of knowledge and skills should a system analyst possess?
- 7. As the diplomat between the various IT and business cultures in an organization, the most important quality of the system analyst is good communication skills. To support this ability to communicate, the system analyst must posses a strong grasp of the many different technological languages, such as programming, hardware and networking, as well as the many levels of business- specific language, such as the terminology used in management's high-level view of the business, the employee-level users‘ terminology for their various tasks, and the customer-level users' perspective on the system.
- 8. What are some of the business drivers for today's information systems?
- 9. E-commerce has expanded competition between companies beyond local communities, forming online communities of customers who may live anywhere in the world and offering a host of new innovations for customer service. Globalization has expanded competition between companies to an international scale, introducing a whole new realm of challenges from language-barriers, differing currencies, and country-specific laws and regulations. Management and decision-makers are now able to gather and manipulate large volumes of metrics for informing business decisions and identifying areas of improvement.
- 10. What are the four steps in a system development process? What happens in each step?
- 11. System development begins with an initiation step, a series of meetings to define the need, establish project scope, budget, and schedule. This is followed with an analysis phase, where user requirements are hammered out in detail, and items like project scope, budget, and goals are adjusted accordingly. The design phase then takes the user requirements and defines in detail various potential technological solutions to the need according to what current technological solutions are currently available and what innovations will impact the current solutions.
- 12. Once designed, the system is implemented, code written, software installed, and everything thoroughly tested and reviewed by the user to ensure quality control. Once implemented, a system is rarely perfect; therefore, the system enters a maintenance or support phase, where user issues with the production system are gathered and addressed with new versions of the system.
