characteristics that an anlayst examines when choosing or defining deployment environment

                The deployment phase is one of the important phases in developing a system or a project. Defining this stage, it is the configuration of computer hardware, system software and networks in which new applications software will operate. The job of the system analyst in phase is to determine the appropriate information to be able to choose from the given alternatives. It can help to decide what alternatives to be used.

                There are some factors that we need to consider in defining the deployment environment.

·         Compatibility with System Requirements

The system analyst should consider some requirements such as user location, speed of access and updates, security, and transaction volume. These requirements have significant impact on environmental requirements. It considers the processes of the systems if it needs high-speed and networks or powerful servers.

·         Compatibility among Hardware and System Software

The system analyst should consider the computer hardware to be used and the system software. Although, the compatibility of the computer hardware and the system software has improved, it is one of the factors needed to be considered. The compatibility of the hardware and the system software simplifies the system’s installation and make it easier to install and can have a good performance.

·         Required Interfaces to External Systems

Some systems nowadays interact with external systems. In implementing external interface, may require fewer requirements. In this way, it can help in minimizing the cost of infrastructure.

·         Conformity with the IT Strategic Plan and Architecture Plan

In Medium-Large scale organization, they have strategic and architecture plan that focus their efforts on a limited set of hardware and software alternatives. It should be consider because it will minimize the cost of infrastructure and maximize the long term compatibility among systems.

·         Cost and Schedule

In developing a system, one of the factor needed to be consider is that the cost of the system. The system analyst should consider the cost of the system. It can help the client to minimize their cost in developing a system.
