Prouct Lifecycle Management

What is Product Lifecycle Management?

PLM is a strategic business approach that manages a product's entire lifecycle from conception through design, manufacture, service, and disposal. It integrates people, processes, business systems, and information to create a centralized knowledge repository for product-related data.

Product Lifecycle Stages

Stage 1: Conception/Ideation Phase

Definition

The birth of a product idea through market analysis, customer needs identification, and initial concept development. This phase involves brainstorming, feasibility studies, and portfolio management decisions.

Key Activities

• Market research and competitive analysis
• Voice of Customer (VOC) collection
• Concept sketching and preliminary requirements
• Business case development
• Portfolio prioritization
• Innovation management

Real-Time Scenarios

Scenario 1: Smartphone Manufacturer Apple's product team analyzes customer complaints about battery life on existing iPhones. They collect data from support tickets, social media sentiment, and competitor analysis. The team creates multiple concepts: a thicker phone with larger battery, a phone with solar charging, or one with battery-saving AI. After feasibility studies considering cost, technology maturity, and manufacturing capability, they select the AI-optimization concept for development.

Scenario 2: Automotive Industry Ford's innovation team notices increasing demand for electric pickup trucks. They conduct surveys with F-150 owners, analyze competitor offerings (Rivian, Tesla Cybertruck), and create three concepts: full EV, hybrid, and range-extender versions. Business analysts calculate market size, required investment, and ROI for each option. The portfolio management committee approves the full EV concept (F-150 Lightning) for development.

Scenario 3: Medical Device Company A surgical equipment manufacturer receives feedback from surgeons about hand fatigue during long procedures. The ideation team collaborates with hospital partners, observes surgeries, and generates 15 different ergonomic handle concepts. They use digital prototyping to test grip patterns, conduct focus groups, and narrow down to 3 concepts for patent filing and further development.
