Introduction

The Product Life Cycle (PLC) describes the stages a product goes through from introduction to withdrawal from the market. Understanding where a product is in its life cycle helps marketers develop appropriate strategies for pricing, promotion, distribution, and product modifications.


Stage 1: Introduction

CharacteristicDescription
SalesLow, slow growth
ProfitsNegative (high costs, low volume)
CustomersInnovators (2.5% of market)
CompetitionFew or none
FocusProduct awareness, trial

Strategies

  • Skimming: High price to recover R&D costs
  • Penetration: Low price to build market share
  • Heavy promotion: Create awareness
  • Selective distribution: Build selectively

Stage 2: Growth

CharacteristicDescription
SalesRapidly increasing
ProfitsIncreasing, peak at end of stage
CustomersEarly adopters (13.5%)
CompetitionGrowing number of competitors
FocusMarket share, brand preference

Strategies

  • Improve product quality, add features
  • Add new models and variants
  • Enter new market segments
  • Increase distribution coverage
  • Shift from awareness to preference advertising
  • Lower prices to attract price-sensitive buyers

Stage 3: Maturity

CharacteristicDescription
SalesPeak, then plateau or slow decline
ProfitsDeclining (price competition)
CustomersEarly & late majority (68%)
CompetitionIntense, weaker players exit
FocusDefend share, maximize profit

Strategies

  • Market modification: New users, new uses, more usage
  • Product modification: Quality, features, style improvements
  • Marketing mix modification: Adjust price, distribution, promotion
  • Focus on differentiation
  • Cost reduction for profitability

Stage 4: Decline

CharacteristicDescription
SalesDeclining
ProfitsLow or negative
CustomersLaggards (16%)
CompetitionDeclining number
FocusDecide: maintain, harvest, or divest

Strategic Options

  • Maintain: Continue if still profitable
  • Harvest: Reduce costs, milk remaining sales
  • Divest: Sell or discontinue
  • Revitalize: Find new markets or uses (rare success)

Strategic Implications Summary

Marketing Mix Changes Across Stages:
Product: Basic → Enhanced → Differentiated → Rationalized
Price: High/Low → Lower → Lowest → Rising
Promotion: Awareness → Preference → Loyalty → Minimal
Distribution: Selective → Intensive → Intensive → Selective

Conclusion

Key Takeaways

  • Products pass through four stages: Introduction, Growth, Maturity, Decline
  • Introduction: Build awareness, losses are expected
  • Growth: Maximize market share, profits peak
  • Maturity: Defend share, differentiate, extend life cycle
  • Decline: Decide to maintain, harvest, or divest
  • Marketing strategies must adapt to each stage
  • PLC length varies by product category and industry
