MARK2012 · Marketing Fundamentals
Developing New Products and the Product Life Cycle
Week 4 also covers the new-product development (NPD) process, the diffusion-of-innovation adopter curve, and the product life cycle (PLC) with its marketing-mix implications. These frameworks let you evaluate innovation decisions and stage-appropriate strategy in the Leadership Presentation and the group Business Report. Ground them in the Week 4 “New Product Development” podcast.
What this chapter covers
- 01The NPD process: idea generation → screening → concept development & testing → business analysis → development → test marketing → commercialisation
- 02Idea screening and concept testing to kill weak ideas early
- 03Diffusion of innovation: innovators, early adopters, early majority, late majority, laggards
- 04The product life cycle: introduction → growth → maturity → decline
- 05Marketing-mix shifts across PLC stages (especially price and promotion)
- 06Managing risk in innovation; test markets before full launch
Applied: placing a product on the PLC and adjusting the mix
- +1(a) Stage: sales are high but growth is slowing and competition is intense — this is the maturity stage of the PLC.
- +1(b) Mix implication 1 (Price/Promotion): with many rivals, competition intensifies on price and promotion — defend share with differentiation, loyalty and value messaging rather than launch-style awareness spend.
- +1(b cont.) Mix implication 2 (Product/Place): extend the line or add features to refresh the offer and seek new segments/markets to prolong maturity.
- +1(c) Adopters: in maturity the mass market is buying — the late majority (more sceptical, price-sensitive adopters) join after the early majority.
Key terms
- New product development (NPD)
- The staged process from idea generation and screening through concept testing, business analysis, development, test marketing and commercialisation.
- Concept testing
- Presenting a product concept to target customers early to gauge appeal before costly development.
- Diffusion of innovation
- How a new product spreads through adopter groups: innovators, early adopters, early majority, late majority and laggards.
- Product life cycle (PLC)
- The sales/profit path of a product across introduction, growth, maturity and decline, each needing a different marketing mix.
- Test marketing
- Launching a product in a limited market to assess demand and refine the mix before full commercialisation.
- Early adopters
- The opinion-leading group who adopt soon after innovators and strongly influence the early majority.
Developing New Products and the Product Life Cycle FAQ
Why screen ideas so early in NPD?
Screening kills weak ideas before the firm spends heavily on development and launch, where costs balloon. Concept testing with real target customers early is far cheaper than a failed test market or launch, so the process front-loads the go/no-go decisions.
How does the marketing mix change across the PLC?
In introduction you invest in awareness and often price to penetrate or skim; in growth you build distribution and preference; in maturity you defend share with differentiation, loyalty and price/promotion competition; in decline you harvest or divest. Reading the stage tells you which mix moves are sensible.
Where do NPD and the PLC appear in the assessment?
They support the Leadership Presentation and the group Business Report when you evaluate an innovation or recommend stage-appropriate strategy, and the NPD podcast feeds the PodQuiz. You are rewarded for matching the recommendation to the correct life-cycle stage.
Can Sia help me with the NPD process and the product life cycle in MARK2012?
Yes, as a study aid. Sia can explain the NPD process and the product life cycle step by step, walk through a worked application to a real brand, and check whether your reasoning uses the framework correctly for your reflection, presentation or report. It teaches the method and checks your thinking; it does not complete graded assessment for you, and the UNSW academic-integrity policy applies — confirm assessment rules on Moodle.
Assessment move
Learn the NPD stages in order and the four PLC stages with their tell-tale sales/competition signals, then practise diagnosing which stage a real product is in and what the mix should do next. Link the adopter curve to the PLC — innovators/early adopters in introduction and growth, the majorities in maturity. Keep the NPD podcast notes for the PodQuiz, reference innovation claims (Harvard), and confirm the Week 4 schedule on Moodle.
