Information Systems Life Cycle

The life cycle of a time entry system includes numerous steps to be successful. The first step to solving the time card issue would be planning. The goals that we are hoping to achieve need to be defined and we need to clearly establish what we are hoping to achieve when creating this system. The problems that we want to solve with the new system have already been laid out and the system development can begin.
Next, the project goals need to be turned “into defined functions and operation of the intended application” (Kay, 2002). It will also be necessary to analyze the needs of the end user. When these things have been completed, the system design begins. The features and designs are described in detail to include rules, layouts, process diagrams, and pseudo code.
The next step is implementation, or the writing of the actual code. Integration and testing comes next. This process works to get all of the bugs and kinks out of the system so that its ready to go live. Going live with the system is the next step in the life cycle process. Deploying the system that has been developed can be one of the biggest, most crucial steps in the process because the workforce that is using it must be eased into it.
The last step of the life cycle process is to perform regular and necessary maintenance on the system. This includes making “changes, corrections, (and) additions” (Kay, 2002). Maintenance continues until the system is no longer in use. Maintenance is very important to keep the system up to date and working as efficiently as possible.
