Product Life Cycle: Definition, Phases, and Integration with Portfolio Management

PMBOK v8 Definition

The product life cycle is defined as "a series of phases that represent the evolution of a product, from concept through delivery, growth, maturity, and to retirement." Product management is "the integration of people, data, processes, and business systems to create, maintain, and evolve a product or service throughout its life cycle." Product management may initiate programs or projects at any point in the product life cycle to create or enhance specific components, functions, or capabilities.

Why It Matters for the Exam

This concept appears frequently in PMI exam questions testing your understanding of how projects fit within the broader organizational value delivery system. Questions often present scenarios where you must determine whether a new initiative should be a project, program, or portfolio based on where it falls in the product life cycle. Expect situational questions about product management considerations in the "System for Value Delivery" section.

Key Points to Remember (for the exam)

• Definition: Product life cycle phases are: concept → delivery → growth → maturity → retirement
• Key Relationship: A product life cycle often spans multiple programs and projects
• Initiation Flexibility: Programs or projects can be initiated at ANY point in the product life cycle
• Program Scope: In some instances, a program may encompass the full life cycle of a product or service to manage benefits
• Product vs. Project Life Cycle: Product life cycle is broader; project life cycle is contained within product life cycle phases
• Operational Activities: Ongoing product support activities are typically operational in nature, not run as programs or projects
• Value Creation: New programs or projects may add or improve specific components, attributes, or capabilities that create additional value

Typical PMI Exam Example

A company has launched a software product that is now in its maturity phase. The product manager wants to add a new feature to extend market share. According to PMBOK v8, where should this initiative be placed?

Answer: This is a project initiated during the maturity phase of the product life cycle to enhance capabilities and create additional value for customers.

PMI Exam Traps

• Trap: Confusing product life cycle with project life cycle

  • Reality: Product life cycle spans multiple projects and programs; project life cycle is the series of phases a project passes through from initiation to closure

• Trap: Assuming programs only begin at product launch

  • Reality: Programs or projects can be initiated at ANY point in the product life cycle (concept, delivery, growth, maturity, or retirement)

• Trap: Treating ongoing product support as a project or program

  • Reality: Operational support activities are typically operational in nature and NOT run as programs or projects

• Trap: Confusing product management with project management

  • Reality: Product management is a separate discipline with its own body of knowledge, but represents a key integration point within program and project management
