4. Why we need insurance
Have an assurance for ensure the Product/Service ,that they used, can
meet with the pre-defined requirement. IF something happens, someone
will compensate..
Want someone bear the risks/damage
But… is everything can bear?
• Co-operate image?
• Human life?
• Environment?
• Customer trust/Loyalty?
So that many companies want
“having a trusted Uptime solution for their operation.”
