Every product in the market has a journey. It starts as an idea, grows into something useful, becomes popular, and after some time, may lose demand. This journey is known as the Product Life Cycle (PLC). Understanding the Product Life Cycle helps businesses make better decisions at the right time. It allows companies to plan marketing strategies, manage profits, improve products, and stay ahead of competitors.
In simple words, the Product Life Cycle shows how a product moves through five important stages:
Development
Introduction
Growth
Maturity
Decline
Each stage has different challenges, different levels of demand, and different types of strategies. When businesses understand these stages, they can manage products more smartly and reduce risks. In this guide, we will explore each stage in easy and simple English so that anyone can understand it clearly.
Stage 1 – Product Development
The Product Development stage is where everything begins. This is the stage before a product is launched in the market. It involves planning, researching, and building the product.
What Happens in This Stage
During the development stage, companies work on the following activities:
Idea Generation: A new idea is born based on customers’ needs or market opportunities.
Market Research: Businesses study whether people need the product and who the target customers are.
Product Design: Teams design how the product will look and function.
Prototyping: A sample or model is created to test the features.
Testing: The product is tested to check if it solves the problem and works smoothly.
Modifications: Based on feedback, improvements are made.
No Sales Yet: At this stage, the product does not bring any revenue.
