Into Designing

In Systems Design, the third phase in developing, implementing and upgrading a clinical information system, there are three parts taken care of, namely: Functional Specification, Technical Specification and Implementation Planning.

Functional Specification

-    Formulation of a detailed description of ALL system inputs outputs and processing logic required to complete the scope of the project.

-     It includes also data manipulation and output review. Starting point for developing testing plans for verification of the software.

Technical Specification

-       Done to make sure that technical components of the proposed system work in concert with technology and end-user needs and to assist in the development of the implementation plan.

-          Four Elements:

1.) Hardware

2.) Interfaces

3.) Software                      

4.) Conversions

Implementation Planning

-          Development of a detailed implementation plan.

-          Contents of the Plan:

1.) Personnel

2.) Timeframes

3.) Costs and budgets

4.) Facilities and equipment required

5.) Development or implementation tasks

6.) Operational considerations

7.) Human-computer interactions (interfaces)

8.) System test plan
