Study Notes
What is a Product?
- People purchase a bundle of value and not just the products themselves.
- A product is a combination of physical goods, services, and symbolic attributes designed to meet a customer's needs.
What are Goods and Services?
- Services are intangible tasks fulfilling consumer and business needs.
- Goods are tangible products which customers can perceive through senses like sight, smell, taste, hearing, and touch.
- The goods-services continuum displays a spectrum ranging from a pure good to a pure service.
Most Admired Companies
- Apple, Starbucks, IBM, GE, Google, Amazon, Tatas-Taj, L&T-EAIC, Reliance, WalMart, Infosys, Wipro, and Amul are among some of the most admired companies.
Goods or Services - Product Classes
- Consumer (B2C) Products are intended for use by end consumers.
- Business (B2B) products contribute directly or indirectly to the output of other products for resale and are also called industrial/organizational products.
- Some products, such as refrigerators or courier services, can fall into both B2C and B2B categories.
Development of Product Lines
- A product line is a set of related products.
- There is growth limitations if a company concentrates on a single product.
The Product Mix
- A product mix includes the combination of product lines and individual product offerings.
- Product mix width refers to the number of product lines a firm offers.
- Product mix length refers to the number of different products offered.
- Product mix depth refers to the variations in each product a firm markets.
Product Mix Decisions
- Marketers assess a firm's product mix effectiveness in terms of its depth, length, and width.
- Firms may expand their product mixes by acquiring product lines from other firms.
- Line extension involves developing individual offerings appealing to different market segments, while remaining tightly linked to the existing product line.
The Product Lifecycle
- The Introductory Stage involves products potentially introducing new technology to a product category.
- Technical issues and financial losses are common.
- The Growth Stage involves sales volume increasing as new consumers make initial purchases, and early buyers repeatedly purchase the product.
- In the Maturity Stage, sales of a product continue to grow early on, but eventually plateau as the number of potential customers dwindles.
- The Decline Stage experiences innovations and shifts in consumer preferences, leading to a decline in sales.
- Examples in each stage include:
- Introduction - Fiat Abarth cars and lightweight carry-on bags
- Growth - Free Wi-Fi, HDTV, GPS systems, video conferencing, smartphones, and iPads
- Maturity - MP3 players, laptops, and microwaves
- Decline - Pagers, desktop computers, and landline phones
Extending The Product Lifecycle
- Increasing the purchase frequency among current consumers will boost sales, even without new buyers.
- Attracting new consumers who haven't previously used the product will extend the product lifecycle.
New Products, Successes and Failures
- An insignificant point of difference is a common reason for new product failures.
- Insufficient market analysis and a poor product definition are some reasons for new product failure.
- Too little market attractiveness is a common reason for product failure.
- Products with poor designs, poor usability, or insensitivity to customer needs on critical factors do not succeed.
- Timing is a critical component to new product success.
- The number of raw, unwritten ideas starts out at 3000, which ultimately ends up as just 1 commercially successful product.
Winning Products
- Key factors that affect the product success rate are:
- Having a distinct point of difference or a superior product.
- Having a well-defined product before development commences.
- Synergy, or fit, with the firm's R&D and manufacturing capabilities.
- Quality of execution of technological & marketing mix activities.
- Market attractiveness with large markets and high growth.
Stages in the New-Product Process
- New-Product Strategy Development involves identifying new product niches and what the firm does well in the current market.
- Idea Generation involves developing concepts for products.
- Ideas come from employees, consumers, R&D and comeptitors by using brainstorming.
- Screening and Evaluation requires separating good product ideas from bad ones inexpensively.
- Screening process involved weighted point systems and concept tests.
- Business Analysis identifies the product’s features and its marketing strategy, then makes financial projections
- This involves economic, marketing, production, legal, and profitability analyses.
- Development involves creating the prototype product, and testing it in the laboratory and on consumers.
- Market Testing tests the prototypes from the Development stage on a limited scale.
- This involved simulated and test markets.
- Commercialization is the final process of positioning a product into the marketplace.
Competitor Advantage
- Is an advantage gained by offering consumers greater value than competitors offer.
Competitor Map
- Includes a visualization of direct and indirect competitors.
- Example, Eastman Kodak, includes camera manufacturers like Olympus and Fuji, retailers of film, and companies like Shutterfly and Adobe that share photos.
Generic Strategies (Porter)
- Overall Cost Leadership involves low production and distribution costs.
- Differentiation involves creating a unique product line and marketing program.
- Focus involves concentrating efforts on serving select market segments.
Competitive Strategies
- Competitive positions are classified as market leader, market challenger, market follower, and market nicher.
- Market leaders can expand the total demand by encouraging greater product usage, finding new users, and promoting new product uses.
- Protecting market share and expanding market share are common goals.
- A market challenger can attack the market leader, a smaller firm, or a regional firm.
- A sustainable competitive advantage is key to success.
- Attacks can be full frontal or indirect
- Market followers will focus on improving profit instead of market share.
- Market followers can learn from market leaders.
- Serving market niches by targeting sub-segments. -Good strategy for small firms with limited resources
Balancing Customer and Competitor Orientation
- Companies may become excessively competitor-centered, at the expense of customer focus.
- Types of companies:
- Competitor-centered companies
- Customer-centered companies
- Market-centered companies
Threat of Substitution
- Determined by buyer propensity to substitute, relative price performance of substitutes, buyer switching costs, and perceived differentiation of the product.
Primary Characteristics of Segments Segmentation
- Segmentation bases include characteristics describing why segments differ.
- Descriptors are characteristics helping find and reach segments.
- Business Markets consider industry, size, location, and organizational structure.
- Customer Markets consider age/income, education, profession, lifestyles, and media habits.
Business Markets - Macro/Micro Segments
- Macro-segments is the first stage, the "rough cut", considering Industry & Firm size.
- Micro-segments, the second stage, the "fine cut", considers different customer needs, wants, and values within each macro-segment.
Relevant Segmentation
- Geography may be a relevant segmentation descriptor.
Irrelevant Segmentation
- Segmentation by education is irrelevant.
Variables to Segment and Describe Markets
- Consumer markets can be segmented by needs, wants, demographics, lifestyle, usage, and brand loyalty.
- Industrial markets are segmented by size, location, technology, and purchasing procedures.
Segmentation Strategy
- Segmentation is critical for understanding customers and their choices.
STP as Business Strategy
- Segmentation involves identifying segmentation bases and segmenting the market, then developing profiles of the resulting segments.
- Targeting involves evaluating the attractiveness of each segment and selecting target segments.
- Positioning involves identifying possible positioning concepts for each target segment, selecting the chosen concept, developing it, and communicating it.
- These strategies will create and claim value.
