System design is a solution how to approach to the creation of a new system. This important phase is composed of several steps. System design provides the understanding and procedural details necessary for implementing the system recommended in the feasibility study. Emphasis is on translating the performance requirement into design specifications. Design goes through logical and physical stages of development. Logical design reviews the present physical system; prepares input and out put specifications; makes edit; security and control specifications details the implementation plan; and prepares a logical design walkthrough. The physical design maps out the details of physical system; plans the system implementation, devices a test and implementation plan; and specifies any new hardware and software.

The design covers the following:-

(a) Reviews the current physical system.

(b) Prepares output specification.

(c) Prepares input specification.

(d) Prepare edit, security and control specification.

(e) Specifies the implementation plan.

(f) Reviews benefits, cost, target dates and system constrains.
