Question

The implementation stage of the SDLC is when the system is moved into operation where it can be used. What stage PRECEDES the implementation stage and what happens in this preceding stage

Answer 1

The stage that precedes the implementation stage of SDLC is testing and it involves checking the functionality of the system.

System design involves the process of determining an overall system architecture, which typically comprises the following:

• Hardware.

• End users.

• Physical processing components.

• Software.

• Communication channel.

Generally, there are seven (7) main stages in the systems development life cycle (SDLC) model and these include:

1. Planning.

2. Analysis.

3. Design.

4. Development.

5. Testing.

6. Implementation.

7. Maintenance.

From the above, we can deduce that the stage which precedes the implementation stage of SDLC is testing.

During the testing stage of SDLC, a quality assurance (QA) expert checks the system to determine whether or not it is functioning properly before it is deployed for operation, which is where the system can be used.
