Project Life Cycle vs Product Life Cycle
You may think that the project life cycle and the product life cycle are similar; they are not. As a project manager, you should know the difference between these two concepts to align your business objectives with your project objectives.
Since a project produces a product and then ends and the product stays for a longer time, the product life cycle is bigger than the project life cycle.
On the PMP exam, you may see a few questions on this topic, so understand it well.
