Product Life Cycle – Exam Notes

Definition

  • Product Life Cycle (PLC): period from market launch to removal from shelves.
  • PLC model guides decisions on pricing, promotion, distribution, investment, redesign.
  • Managing a product through its stages = Product Life Cycle Management.

Core Stages & Typical Features

  • Introduction
    • \text{Sales} \downarrow | \text{Cost per customer} \uparrow | losses common.
    • Customers: innovators; competitors: few/none.
  • Growth
    • Rapid \text{sales} \uparrow; costs fall per unit; profits rise.
    • Customer base expands; competitors enter.
  • Maturity (incl. saturation / shake-out)
    • Peak \text{sales}; highest profitability; mass market reached.
    • Market becomes saturated; competitive pressure intense; price wars possible.
  • Decline
    • \text{Sales} \downarrow; profits erode; firms exit market.
    • Product may become obsolete or displaced by superior offers.

Marketing Focus by Stage

  • Introduction: heavy promotion, awareness building, selective distribution, possible price skimming/penetration tests.
  • Growth: broaden channels, emphasize differentiation, consider price adjustments to defend share.
  • Maturity: reminder advertising, loyalty programs, cost control, minor product upgrades.
  • Decline: harvest (cut spend), divest, discontinue, or rejuvenate via extension strategies.

Extension Strategies (apply between maturity & early decline)

  • Reposition: new uses/markets, variant sizes, add value.
  • Intensify marketing: fresh campaigns, sales promotions.
  • Product differentiation: reinforce USP, highlight new features.
  • Price reduction: attract switchers, retain existing users.
  • Rebrand/refresh packaging: modern look to regain attention.

Decision-Making Uses of PLC

  • Signals when to invest, cut costs, or relaunch.
  • Informs pricing tactics, promo spend, product mix, R&D pipeline.
  • Helps schedule capacity, forecast revenue, and manage portfolio balance (new vs. aging products).

Context Variations

  • Established brands: longer PLCs; minor tweaks sustain sales.
  • Seasonal/fashion goods: short PLCs; require frequent refreshes.
  • Technology: software updates can extend life, but rapid innovation shortens overall cycle.
  • Fad items: accept brief spikes; rely on broad portfolio.
  • Small firms: closer monitoring enables quicker extension moves.
