Finalization of any system and user documentation.
This can be done by interviewing users of the system and consulting with support personnel. This is the first phase in the systems development process. The sooner, and more often, you can do such testing the better. Upload from Desktop Single File Upload.
Viti Bank is a fast growing bank in Fiji. This step is when end users can fine-tune the system, if they wish, to boost performance, add new capabilities or meet additional user requirements. This exploration effort should be brief, not all projects will make the initial cut so you only want to invest enough effort at this point to get a good gut feel for the business potential.
The system has become obsolete. The goal of the Production Phase is to keep systems useful and productive after they have been deployed to the user community. Before any system planning is done, a feasibility study should be conducted to determine if creating a new or improved system is a viable solution.
The Seven Phases of the System-Development Life Cycle
Every team is unique and faces a unique situation, therefore they must choose and evolve a way of working WoW that is effective for them.
