Life cycle of information technology - Essay Example

Life Cycle of Information Systems Life Cycle of Information Systems Understanding the life cycle of any information system requires a clear evaluation of various integral stages. For instance, during the systems development life cycle (SLDC), there are instances creating, testing, and planning to assess the information system. Therefore, in running an efficient photography printing store, it is critical to first plan how to minimize the loss of cards. In that context, the first phase entails system investigation to suggest alternative solutions and also describe benefits and costs.

It is equally called the preliminary analysis and it hypothesizes on solutions to eradicate inaccurate hours. The second phase is to conduct a system analysis to identify the source of the problem and find mechanisms of fixing it. Consequently, in a photography printing store; it is fundamental to disintegrate the store into parts to define the exact problem. Thereafter, a system design is implemented to outline the operations and functions of the store using process diagrams and other forms of documentations (Kelkar, 2011).

Third, comprehending the environments under which the employees work is vital because it establishes certain critical purposes. It is because it sets a platform for planning, operation and provisioning to achieve user acceptance during testing. Fourth phase of the life cycle encompasses testing of the computerized time entry system for any defects to ascertain the stability of the whole system. However, the second last phase of training and transition is essential to help staff at the photography printing store learn how to use the new system.

Finally, it can operate through a few enhancements and changes during maintenance. ReferenceKelkar, S. (2011). Information Technology Project Management: a Concise Study. Mason, OH: PHI Learning.
