Planning
The next step is we need planning Supppose for example we need to design a robot which will travel to remote locations and capture the images and sent it to the receiver so we need to plan for that
so requirements are
1.remote
2.monitor
3.micro controller
4.regulated power supply
so we got the details next is we need to design the product
Requirement Analysis
We need to collect the hardware components like resistor ,capacitor,microcontroller etc for our product
 Design
In design we need to construct the block diagram and later on we need to develop the schematic diagram schematic means pin to pin connection of the circuit this is possible only by the software called oracad or proteius aries orcad is an open source you can download it
Development
Indevelopment we need to prepare the orginal circuit amd deploy it
Integration testing
In this testing we need to test whether the product is working fine or not
Implementation
Once the product has been developed we need to release it in the market

So for right know we have learnt about what is system development life cycle next we wiil see basic components
