No product grows forever.
Every product follows a lifecycle:
Introduction
↓

Decline
The key to success is understanding:
What Stage
Your Product
Is Currently In
and applying the right strategy.
The essence of Product Lifecycle Management is:
Launch
↓
Grow
↓
Optimize
↓
Adapt
↓
Renew
or
Retire
The businesses that succeed long-term are not the ones that avoid product decline.
They are the ones that recognize lifecycle changes early and adapt before competitors do.
