Extract of sample "The Information Systems Development Life Cycle"

Computer Information Systems (A research essay for DB3)Information systems are the processes that pertain to the study of how people and their organizations collect, filter, process, and distribute raw data to make these into the meaningful information that people can now use; these systems combine hardware and software aspects. In general, when people mention information systems, what is really meant are modern computer information systems widely used today mainly for intelligent decision making (Avison & Shah, 1997).

There are four components (phases) in the systems development life cycle (SDLC) which are planning (ideas), creating (analysis), testing (design), and deploying (implementation). In the photograph printing store, these will be the steps to be taken to migrate to a new computerized and more accurate (tamper-proof) employee time-entry system and analyzes each step.Planning – this is the very first or initial phase of the SDLC and ideas here are discussed such as what the proposed computerize system is expected to solve (problems like the lost punch cards, inaccurate timekeeping, and employee cheating – punching for an absent employee).

The costs will also be discussed and the time frame needed to fully implement this new system. Creating – the hardware requirements will be specified including a software program to run the whole system. Total number of employees, back-up systems, desired features and all other operational details are created at this point so that management expectations can be met.Testing – the new system will be tried if there are kinks or bugs in it so remedies and patches can be applied immediately prior to actual implementation and avoid future problems.

Deploying – once the new system is complete and fully operational (bug-free), it will now be implemented throughout the entire store and employees are required to use it. The new system can then be integrated into the firm’s payroll system to automatically compute wages and salaries for the employees based on their time records to generate a payroll (Oz, 2009).ReferencesAvison, D.
