System Engineering Fundamentals: System Life Cycle

According to View point three life cycles interest the System Engineer.

System Life Cycle:

From initial step to disposal of the system.

Project Life Cycle:

From bid phase up to the project phase.

Software Development Life Cycle:

From the decision of the development up to the delivery of the system.

To clarify the differences between System Life cycle, Project Life Cycle and Development Cycles. We will breakdown each life cycle into further detailed view.

We will break down the blog into three parts.

In today’s blog, we will have an overview of System life cycle.

System Life Cycle

The lifecycle of a system represents everything that happens between the moments the initial idea of system springs forth from a market survey, invitation for bid or customer request, until the moment system completed its life span. During the life cycle of the system we have following stages.


            Capture the needs and develop the concept of system Solution.


            Design the solution; make sure the developed solution is aligning with concept and customer needs. Have initial view point with customer and consultant approval.


Deploy the system on site taking into consideration by the feedback received from Customer and consultant at development phase.

Training, Support & Operation Maintenance

Trained the end user. Upgrade the system with passage of time if needed. Provide preventive and corrective maintenance support on monthly, quarterly and annual basis.


Life span of system normally tends from 10 to 15 years .Upon the completion of system life, support to dispose the system.
