This week talked about the Information Systems and those who utilize this (System Analysts). What exactly is a system? It is a collection of interrelated components that interact with each other to a achieve a certain goal. A good correlation to this is the Ecosystem. In comparison, an information system deals with a collection of hardware, software, data, people and processes that work together to produce quality information. The System Development Cycle involves planning, analysis, design, implementation, operation, support and security. This cycle repeats over and over again, however, humans' intelligence are still needed to keep its functionality. System Analysts, often called Program Managers, put projects together and help to keep everything moving along smoothly. They enable other people to do work efficiently and effectively. They create road maps to get things done. The key to this is *communicaiton*.
A system analyst must derive the benefits and risks associated with a certain system. A well designed system is effective, easy to use and meets objectives. Poorly designed systems cost more than their value. They are hard to understand or use and are not dependable. The SDC (System Development Cycle) was develped to improve quality and create an overal better system. A great system analyst must accept certain leader responsibilities. This includes setting goals, objectives, expectations, estimating time constraints, estimating cost, defining order of activities and deciding the relationship of those activities. In conclusion, there are a plethora of reasons why there should be effective information systems and system analysts.
