Product Life Cycle

The Product Life Cycle (PLC) is a concept derived from the biological life cycle. Just as living beings go through stages of birth, growth, maturity, and eventual decline, so do products and services. Understanding the PLC is critical for businesses to plan strategies tailored to each stage of a product’s market life.

Stages of the Product Life Cycle

  1. Introduction Stage

    • Analogy: A seed is planted.
    • Description: The product is launched in the market. It is new, and awareness is low.
    • Characteristics:
      • High costs due to marketing, research, and distribution efforts.
      • Sales grow slowly as the market learns about the product.
      • High risk of failure; many products do not move beyond this stage.
      • Profits are minimal or negative.
    • Strategies:
      • Focus on creating awareness through advertising and promotions.
      • Target early adopters and innovators.
      • Build strong distribution channels.

  2. Growth Stage

    • Analogy: The seed begins to sprout.
    • Description: The product gains acceptance, and sales increase rapidly.
    • Characteristics:
      • Rising sales and profits as the market expands.
      • New competitors may enter the market with similar offerings.
      • Economies of scale start to lower production costs.
    • Strategies:
      • Focus on differentiating the product from competitors.
      • Expand distribution to reach a wider audience.
      • Invest in customer satisfaction to build loyalty.

  3. Maturity Stage

    • Analogy: The plant reaches adulthood, with stable growth.
    • Description: Sales peak as the product becomes widely accepted.
    • Characteristics:
      • Slower growth, with market saturation approaching.
      • Price competition increases as more players enter the market.
      • Profit margins may shrink due to competitive pressures.
    • Strategies:
      • Diversify product offerings with variations or updates.
      • Use promotions to sustain market share.
      • Focus on retaining existing customers and maximizing efficiency.

  4. Decline Stage

    • Analogy: The plant begins to shrink and eventually dies.
    • Description: Sales and profits decline as customer interest wanes.
    • Characteristics:
      • Reduced demand due to changing preferences or newer alternatives.
      • High inventory costs and shrinking profitability.
      • Companies may exit the market or reposition the product.
    • Strategies:
      • Decide whether to rejuvenate the product through innovation or discontinue it.
      • Focus on niche markets if the product still holds value for specific customers.
      • Minimize costs and optimize inventory management.

6.4.2 Product Life Cycle : Conceptual Framework

The Product Life Cycle (PLC) is a widely used framework in marketing and business strategy. It represents the stages a product goes through in the market, from its introduction to its eventual decline. The curve of the PLC is typically S-shaped, representing sales or other performance metrics over time.

Stages of the Product Life Cycle

  1. Introduction Stage

    • Description: The product is launched into the market.
    • Characteristics:
      • Low sales and high costs.
      • No or minimal profits.
      • High marketing expenses to build awareness and establish a distribution network.
      • High risk of failure as market acceptance is uncertain.
    • Challenges:
      • Overcoming competition and building trust among early adopters.
      • Ensuring product quality and managing production efficiently.
    • Strategies:
      • Invest in advertising and promotions to create awareness.
      • Use penetration pricing (low price) or skimming (high price for premium positioning).
      • Focus on niche markets and early adopters.

  2. Growth Stage

    • Description: The product gains market acceptance and sales increase rapidly.
    • Characteristics:
      • Rapid growth in sales and rising profits.
      • Entry of competitors into the market.
      • Increased economies of scale reduce production costs.
      • Market share becomes a critical focus.
    • Challenges:
      • Maintaining product quality amidst scaling.
      • Differentiating from competitors to sustain growth.
    • Strategies:
      • Expand distribution channels to reach more customers.
      • Enhance the product with features or variations.
      • Focus on customer satisfaction to build loyalty.

  3. Maturity Stage

    • Description: Sales growth slows down as the product reaches its peak in market penetration.
    • Characteristics:
      • Sales stabilize or begin to decline gradually.
      • Maximum profits are often realized during this phase.
      • High competition leads to pricing pressures.
      • Customers may become bored or look for alternatives.
    • Challenges:
      • Retaining existing customers and keeping the product relevant.
      • Avoiding complacency and preparing for market shifts.
    • Strategies:
      • Diversify the product line (e.g., new variants, bundles).
      • Focus on cost control to sustain margins.
      • Engage in promotional activities to maintain interest.
      • Explore new markets or customer segments.

  4. Decline Stage

    • Description: Sales and profits decline as the product loses relevance or competition offers better alternatives.
    • Characteristics:
      • Shrinking market demand and reduced profitability.
      • High inventory costs as sales decrease.
      • Product obsolescence due to technology or changing preferences.
    • Challenges:
      • Deciding whether to rejuvenate or phase out the product.
      • Managing declining resources effectively.
    • Strategies:
      • Consider product rejuvenation with updates or innovations.
      • Target niche markets that still find value in the product.
      • Phase out the product to reduce losses.

The PLC Curve

  • X-axis: Time.
  • Y-axis: Performance metric (e.g., sales, profits, return on investment).
  • The curve typically shows sales or profits against time:
    • Introduction: Slow growth, low sales.
    • Growth: Rapid increase in sales and profits.
    • Maturity: Sales plateau, maximum profits.
    • Decline: Sales and profits drop.

Key Observation:

  • Most products fail in the Introduction Stage due to lack of market acceptance or inability to compete.
  • The Maturity Stage often delivers the maximum profits, but brands must identify when to innovate or retire the product to avoid a decline.

Application of the PLC

  1. Data Dependency:

    • To analyze a product's life cycle, reliable historical data on sales or profits is essential.
    • For new products, industry or competitor data can offer insights.

  2. Examples:

    • Music Industry:
      • Evolved through vinyl records, tapes, CDs, MP3 players, and streaming services.
      • Each format had its own PLC within the broader industry's life cycle.

  3. Limitations:

    • If a product is too new (e.g., a month old), there won’t be enough data to draw its PLC curve.

6.4.3 Product Introduction Phase

The Introduction Stage is the phase where a new product is introduced to the market. During this stage, the product faces several challenges and requires significant investment to create awareness, establish distribution, and induce customer trials.

Key Characteristics of the Introduction Stage

  • Slow Sales Growth:
    Sales grow slowly as the product is newly launched, and production capacity is often limited.

    • Technical problems may arise.
    • Distribution channels (wholesalers, retailers, etc.) may take time to establish.

  • Profitability:
    The product may not generate any profit, or if it does, it is very low. The company spends heavily on marketing and establishing the product.

  • High Promotional Expenditure:
    In comparison to sales, promotional spending is very high during this stage. The aim is not only to promote the product to customers but also to persuade distributors and retailers to carry the product.

  • Reluctant Customers:
    Customers may be hesitant to try out a new product, especially if they are unsure of its quality or benefits. Overcoming this reluctance is a challenge for marketers.

  • High Price:
    Since production is not at scale, and the product is new with limited market share, the price tends to be on the higher side.

Strategic Approaches in the Introduction Stage

During the introduction phase, different strategies can be adopted based on pricing and promotional efforts. These strategies can be categorized into four types:

1. Rapid Skimming

  • Price: High
  • Promotion: High
  • Description:
    • Aimed at a large potential market, but a significant portion is unaware of the product.
    • Those who are aware of the product are willing to pay a premium.
    • Competition is imminent, so brand preference must be built early.
  • Example:
    • New technology products such as smartphones, new TVs, or innovative home appliances.

2. Slow Skimming

  • Price: High
  • Promotion: Low
  • Description:
    • The target market is relatively small and selective.
    • Customers are willing to pay a premium for the product, and competition is not very intense.
    • This approach is often used for luxury products.
  • Example:
    • Luxury watches, high-end designer brands, and exclusive high-tech gadgets.

3. Rapid Penetration

  • Price: Low
  • Promotion: High
  • Description:
    • Used when the market is large, and a significant portion of the market is unaware of the product.
    • This approach is common for FMCG (Fast-Moving Consumer Goods) products, where the focus is on achieving wide distribution and generating awareness at scale.
    • Competitive pressures are strong, and the product must be marketed aggressively.
  • Example:
    • Toothpaste brands, new snack foods, or budget-friendly household products.

4. Slow Penetration

  • Price: Low
  • Promotion: Low
  • Description:
    • Typically seen in commodity markets or when a new product is entering a price-sensitive market.
    • The goal is to create initial awareness while keeping costs low.
    • The focus is on generating market share slowly, with limited promotional efforts.
  • Example:
    • Commodity goods like basic household items or new tech products aimed at a price-conscious audience.

6.4.4 Market Growth Phase

The Growth Stage marks a period of rapid growth and expansion for the product. It is the phase where the product gains wider acceptance, more customers, and increased profitability. However, this stage is also characterized by the entry of competitors into the market, which makes it crucial to maintain momentum for as long as possible.

Key Characteristics of the Growth Stage

  • Rapid Sales Growth:
    Sales grow quickly as the product gains market acceptance. More customers are buying the product, and production capacity is often expanded to meet this demand.

  • New Product Features:
    To stay competitive and appeal to a broader audience, new features or models of the product may be introduced.

  • Expansion of Distribution:
    As demand increases, companies expand their distribution network to reach more customers. New retail channels and wholesalers may be involved in the product's distribution.

  • Price Stability or Slight Reduction:
    Prices generally remain stable or may decrease slightly due to increased production efficiency or to attract more customers. In some cases, lowering the price can help expand market share.

  • Increased Promotion:
    Since competition starts to rise during the growth phase, promotional efforts might be increased to highlight the product’s superiority over competitors.

  • Profit Increase:
    As the product becomes more widely accepted, profits begin to rise due to economies of scale and a larger customer base.

Strategy in the Growth Stage

The Growth Stage is considered the "golden phase" for a company because of rapid growth and profitability. However, it is also the shortest stage in the product life cycle. As more competitors enter the market, the company must work to extend its position in the growth phase for as long as possible.

Objective:

  • Stay in the Growth Phase as Long as Possible:
    The goal is to maximize the growth potential before competition intensifies, leading to the maturity phase.

Strategic Actions:

  1. Product Improvement:

    • Enhance product quality and style to meet customer needs and differentiate from competitors.
    • Introduce new features or models to keep the product fresh and attractive to customers.

  2. Flanker Products:

    • To capture a wider market, companies can introduce flanker products — variations of the product aimed at different customer segments.
    • If the product was initially targeted at one specific demographic (e.g., 15 to 30-year-olds), the company can expand to other age groups or market segments (e.g., 30 to 40, 40 to 50, etc.).

  3. Increase Market Coverage:

    • Expand the product's availability by increasing distribution channels. This ensures the product reaches as many customers as possible.
    • Offer incentives to distributors, wholesalers, and retailers to encourage them to prioritize the product.

  4. Increase Advertising and Promotion:

    • Shift the focus of advertising from raising awareness to highlighting the product's performance and superiority over competitors.
    • Promote the product's unique benefits to create customer loyalty and reinforce its market position.

  5. Price Adjustment:

    • Lowering the price slightly can help increase market share, especially if the product is well-established and competition is beginning to emerge.
    • Competitive pricing can also act as a barrier to new entrants, making it harder for them to gain traction in the market.

  6. Create Barriers to Entry for Competitors:

    • As more competitors enter the market, creating strong barriers to entry is critical.
    • By expanding market share, enhancing product offerings, and solidifying relationships with distributors, the company can make it more difficult for new competitors to challenge its position.

Example of Growth Stage in the Market:

  • Smartphones: As the smartphone industry grew, companies like Apple and Samsung continuously introduced new features, expanded their market reach, and enhanced their product offerings to stay ahead of competitors.
  • Fitness Trackers: When fitness trackers became popular, companies offered models with additional features, improved designs, and expanded into new demographic markets (e.g., targeting both casual users and professional athletes).

6.4.5 Maturity Phase

The Maturity Stage is characterized by a slowdown in sales growth and the stabilization of market position. It is the longest stage in the product life cycle, and the product typically becomes well-established in the market. However, competition is intense, and maintaining market share becomes more difficult. The maturity stage can be broken down into three types: Growth Maturity, Stable Maturity, and Decaying Maturity.

Key Characteristics of the Maturity Stage

1. Growth Maturity:

  • Sales Growth Slows: The rate of sales growth slows down but remains positive. New customers are harder to find, and new distribution channels are not needed anymore.
  • Stable Market: The market for the product becomes saturated, and growth primarily comes from population increases and replacement demand.

2. Stable Maturity:

  • Sales Plateau: Sales begin to flatten on a per capita basis. The product reaches a point where no significant growth is possible in the target market. Revenue growth stagnates.
  • Zero or Near-Zero Growth: The product’s growth slows to zero, and further sales are determined by demographic factors or the need for replacement, not new customer acquisition.

3. Decaying Maturity:

  • Declining Sales: Absolute sales start to decline as customers begin switching to substitute products.
  • Saturation and Overcapacity: The market becomes saturated, and overcapacity in the industry leads to declining demand.
  • Increased Competition: New competitors or existing competitors intensify their efforts to capture market share, leading to increased marketing, price cuts, and trade promotions.

Challenges in the Maturity Stage

  • Overcapacity: Too many products are available in the market, and there is not enough demand to sustain all competitors.
  • Boredom: Consumers may grow bored of the product, leading to a loss in interest.
  • Intensified Competition: As the market becomes saturated, competitors fight for a larger share, often leading to price wars and aggressive marketing.
  • Customer Switching: Customers start switching to newer or more appealing substitute products that better meet their needs.

Decision Objectives in the Maturity Stage

At this point, companies face critical decisions:

  • Become One of the Big 3: Aim to be a cost leader, quality leader, or service leader in the market.

    • Cost Leader: Optimize distribution and manufacturing processes to offer the lowest price.
    • Quality Leader: Provide the highest quality product in the market.
    • Service Leader: Offer superior customer service and support.

  • Niche Strategy: Alternatively, some companies may focus on smaller, specialized segments, offering customized products at a premium price.

    • Companies can either aim for high-volume, low-margin or low-volume, high-margin strategies, depending on the product and market dynamics.

  • Market Focus: Decide which markets or products to abandon and which to concentrate on. This may involve reducing product lines or shifting focus to more profitable segments.

Strategies in the Maturity Stage

The goal of the Maturity Stage is to stay relevant in the market for as long as possible. To achieve this, companies typically use several strategies:

1. Market Modification:

  • Increase the Volume: Focus on increasing the usage rate or converting non-users into users.
    • Example: A toothpaste brand encourages consumers to brush twice or three times a day, increasing the frequency of use.
  • Expand Market Segments: Enter new demographic segments or geographic markets.
    • Example: A brand targeting adults might expand into the senior citizen or child markets.
  • Win Competitor's Customers: Offer promotions or incentives to attract customers away from competitors.
  • Increase Product Usage: Encourage customers to use the product more frequently, thereby increasing sales.

2. Product Modification:

  • Improve Product Quality: Enhance the product’s features, style, or design to make it more appealing.
  • Add New Variants: Introduce new models, versions, or variations to refresh the product line.
    • Example: A smartphone company releasing upgraded models with better features and design.

3. Marketing Mix Modification:

  • Adjust Price, Distribution, or Promotion: Modify elements of the marketing mix, such as adjusting prices, changing promotional strategies, or expanding distribution channels.
    • Example: Offering sales promotions, discounts, or bundling products to encourage purchases.
  • Increase Advertising: Focus on maintaining awareness and loyalty through advertising campaigns that emphasize product benefits or emotional appeal.

Fragmentation and Reconsolidation in the Maturity Stage

The Maturity Stage is marked by continuous fluctuations in market share. As companies introduce promotions and discounts to gain market share, competitors do the same, leading to a constant shift in customer loyalty and market position. This creates a dynamic environment where companies must continuously adjust to maintain their position.

  • Price Wars: Companies may engage in frequent price cuts or special offers to attract customers, leading to a cycle of reconsolidation and fragmentation in the market.
  • Short-Term Gains: Promotions like "buy one, get one free" or "20% off" can lead to temporary increases in sales, but these may not be sustainable long-term.

Example of Maturity Stage in the Market:

  • Toothpaste: Brands like Colgate and Oral-B have been in the maturity stage for years, focusing on increasing usage frequency (e.g., brushing more times a day), introducing new variants (e.g., with different flavors or added benefits like whitening), and running frequent promotions.
  • Smartphones: Established smartphone brands like Apple and Samsung dominate the market with new models, frequent updates, and strong brand loyalty.

By executing the appropriate strategies, companies can extend their product’s life in the Maturity Stage and maintain a competitive edge before transitioning to the Decline Stage.

6.4.6 Market Decline Phase

The Decline Stage represents the final phase of the product life cycle where sales and profits begin to decrease. This decline can occur slowly or rapidly, depending on various market factors. Ultimately, the product faces obsolescence due to technological advancements, changing customer preferences, increased competition, and overcapacity within the industry.

Key Characteristics of the Decline Stage

1. Declining Sales:

  • Sales of most products or brands in this phase begin to decline.
  • The decline can be gradual or sudden, depending on factors such as market saturation, technological advances, and consumer shifts.

2. Technology Obsolescence:

  • Technological advancements make older products outdated, leading to reduced demand.
  • New innovations can render previous models or versions of products less relevant.

3. Change in Customer Preferences:

  • Consumer preferences shift towards newer or more innovative products, contributing to the decline of older ones.

4. Increased Competition:

  • The entry of new competitors, or the growing offerings from existing companies, exacerbates the decline, especially if the product is no longer a market leader.

5. Overcapacity in the Industry:

  • Overcapacity occurs when the market becomes flooded with too many similar products, resulting in a price war as companies struggle to maintain their market share. This reduces overall profitability.

  • High Exit Barriers and Low Entry Barriers: Companies often find it hard to exit the market even if they no longer see profitability due to high exit barriers, leading to continued competition, even in a declining market.

Factors Contributing to Decline

  • Price Wars: Intense price cutting and frequent promotions to attract remaining customers.
  • Profit Reduction: As competition increases and demand shrinks, profit margins also decrease.
  • Market Withdrawal: Companies begin withdrawing from unprofitable segments, be it geographic, demographic, or product-specific, focusing only on core areas.
  • Reduced Offerings: Companies reduce their product range and only offer the most basic, core products to maintain relevance.

Strategic Decisions in the Decline Stage

The primary decision at this stage is how long to stay in the market and when to exit. Companies must evaluate whether they can turn the market around, enter a new segment, or introduce a new product to begin a new life cycle. The following strategies can help navigate the decline stage:

1. Increase Investment:

  • Strategy: Increase the firm’s investment if there is potential for future growth, such as through research and development (R&D) for new technologies or products.
  • Objective: Keep the market "warm" for the future, possibly capitalizing on future opportunities like a new product launch.
  • Example: A company continues investing in a declining product while working on a new, innovative version to revitalize the brand.

2. Maintain Investment:

  • Strategy: Continue to invest in the declining product but adopt a "wait and watch" approach.
  • Objective: Observe the market for signs of a potential rebound or future opportunities before deciding to exit completely.
  • Example: A company keeps its product in the market but does not push for major new investments, maintaining its position until further market signals are clear.

3. Selective Investment Reduction:

  • Strategy: Gradually reduce investments, focusing only on the most profitable or relevant market segments.
  • Objective: Cut costs and minimize losses while withdrawing from less profitable markets.
  • Example: A brand stops offering discounts or promotions in non-core geographic areas but continues in select profitable markets.

4. Harvesting:

  • Strategy: Gradually reduce resources allocated to the product, aiming to "milk" as much profit as possible before the product completely declines.
  • Objective: Allow the product to "die a slow death" by withdrawing investments, reducing promotions, and minimizing product offerings.
  • Example: A company reduces the product's marketing efforts and limits its distribution channels, extracting any remaining value while accepting a decline in sales.

5. Divesting:

  • Strategy: Sell the product or brand to a competitor or another entity interested in entering the market or revitalizing the product.
  • Objective: Exit the market while extracting value by selling the brand or product to another company.
  • Example: A company sells off a declining product line to a competitor who believes they can turn it around or gain value from it.

6.4.7 Concluding PLC

Multiple Shapes of the Product Life Cycle

The PLC is often represented as a typical S-shaped curve, but there are different possible patterns depending on the product or market. Here are some variations of the PLC curve:

1. Scalloped Pattern:

  • This pattern indicates that a product goes through multiple cycles of growth and decline. The product experiences ups and downs, with periods of revival and decline.

2. Style Cycle:

  • In this type, the product experiences repeated cycles of popularity, often with alternating periods of growth and decline. This is typically seen in products that are based on changing tastes or trends.

3. Fashion Cycle:

  • This cycle is longer than the style cycle and usually reflects broader shifts in consumer preferences over time. Fashion products have a more extended growth period before they eventually decline.

4. Fad Cycle:

  • A fad is a product that experiences a rapid rise in popularity followed by a sharp decline. This type of cycle is typically very short, with products becoming obsolete almost overnight.

The point of highlighting these different patterns is to emphasize that the shape of the life cycle is not fixed; it can vary depending on the type of product and its market dynamics.

Importance of Understanding Life Cycles

A brand or product typically goes through four stages in the PLC:

  1. Introduction: The product is launched, and sales start to grow.
  2. Growth: The product sees a significant increase in sales and market adoption.
  3. Maturity: Sales begin to plateau as the product reaches widespread acceptance and market saturation.
  4. Decline: Sales start to decrease due to factors such as technological obsolescence or changing consumer preferences.

Understanding these stages helps businesses develop better strategies for each phase, ensuring they maximize the potential of the product life cycle.

Industry Life Cycle

While the PLC applies to a single product or brand, it's crucial to also understand the Industry Life Cycle. This refers to the stages that an entire industry undergoes as it evolves. For example, an industry like television involves multiple brands and products, and each of these products will go through their own life cycles, but they all contribute to the overall industry life cycle.

Example: The Music Industry

Consider the music industry, which has evolved from vinyl records to tapes, then to CDs, MP3 players, and now, music is primarily consumed through streaming services via smartphones. Throughout this journey, many products (such as CDs, MP3 players) and brands (such as specific audio device manufacturers) have entered and exited the market. However, the music industry itself has had a continuous life cycle, going through changes in how music is produced, distributed, and consumed.

Impact of Industry Life Cycle

When analyzing a product's position in the life cycle, it is equally important to consider where the industry itself is positioned:

  • Is the industry in the introduction phase while the product is in the growth phase? This could signal significant potential for expansion and innovation.
  • Is the industry in the maturity phase, with the product still in its growth phase? In this case, the company may face stiff competition, and it becomes more challenging to maintain momentum.

The industry life cycle can significantly impact the strategies companies must adopt for their product. For example, if a product is in the growth phase, but the industry is in the maturity phase, the market could be near saturation, making it more difficult to achieve sustainable growth.

Other Life Cycles Influencing Product Strategy

Along with the product and industry life cycles, there are other types of life cycles that also influence decision-making:

1. Technology Life Cycle:

  • New technologies often disrupt established markets and create new product opportunities. Understanding the technology life cycle is vital for anticipating product obsolescence or identifying emerging opportunities.

2. Brand Life Cycle:

  • The brand itself can experience a life cycle, from introduction to growth, maturity, and possibly decline. The strategies used to manage a brand through these stages might differ from those applied to the product life cycle.

How to Develop Effective Strategies

The primary purpose of understanding the product life cycle is to develop better strategies that align with each phase. By identifying which stage the product is in, companies can tailor their approach and improve their chances of success.

  1. Plot Sales vs. Time: By charting sales against time, you can visualize the product's life cycle and identify which phase it's currently in.
  2. Stage Identification: Once you identify the stage, you can decide on the appropriate strategy.
    • For example, during the growth phase, a strategy focused on expansion and market penetration would be ideal, while in the decline phase, a harvesting or divestment strategy might be more suitable.
  3. Data-Driven Decisions: Understanding the theory behind PLC and using real-world data about product performance allows for smarter strategic decisions, reducing the risk of failure.

Conclusion

The Product Life Cycle (PLC) offers a valuable framework for understanding how a product evolves over time, helping businesses strategize for each stage of the process. However, it's essential to also recognize the influence of broader life cycles such as industry life cycle, technology life cycle, and brand life cycle.

By considering these multiple layers of life cycles and the various possible product cycle shapes, companies can better navigate challenges, predict trends, and develop more effective strategies. Recognizing which stage a product is in—whether growth, maturity, or decline—will allow businesses to make informed decisions and ultimately extend the life of their products in a competitive market.
