Step-by-step explanation:
The reason for the increased popularity of project management is all of the above options: diversity of new products and product markets, shorter life span of products, and rapid technological changes.
Project management helps organizations effectively manage and coordinate various projects, ensuring successful completion within budget and time constraints. With the diversity of new products and product markets, organizations need project management to plan, execute, and monitor projects efficiently.
