64 Service Marketing
64.1 What is a Service?
A service is any act or performance one party can offer to another that is essentially intangible and does not result in the ownership of anything — Kotler’s classic definition (kotlerkeller2022?). Services dominate modern economies — over 60 per cent of India’s GDP is services and the share is rising. Services marketing is the body of theory and practice that addresses the special challenges of marketing services.
Valerie Zeithaml, Mary Jo Bitner and Dwayne Gremler’s standard textbook Services Marketing anchors most academic discussion of the field (zeithaml2018?).
TipThree Working Definitions
| Author | Definition | What it foregrounds |
|---|---|---|
| Philip Kotler | “Any act or performance that is essentially intangible and does not result in ownership.” | Intangibility |
| Christopher Lovelock | “An economic activity creating value and providing benefits for customers at specific times and places.” | Value at point of consumption |
| Zeithaml & Bitner | “Deeds, processes and performances provided by one entity for another.” | Performance |
64.2 The Four Characteristics — IHIP
Services have four classical characteristics — the IHIP model:
TipIHIP — Four Characteristics of Services
| Letter | Characteristic | What it captures | Marketing implication |
|---|---|---|---|
| I | Intangibility | Services cannot be touched or stored | Use tangible cues — physical evidence |
| H | Heterogeneity | Performance varies | Standardise + train staff |
| I | Inseparability | Production and consumption simultaneous | Customer is part of the service |
| P | Perishability | Cannot be inventoried | Manage demand and capacity |
64.3 The Services Marketing Mix — 7 Ps
Booms and Bitner (1981) extended the 4 Ps to 7 Ps for services (boombitner1981?):
TipThe 7 Ps of Services Marketing
| P | What it covers |
|---|---|
| Product | Service offering, benefits |
| Price | Pricing methods, dynamic pricing |
| Place | Channels, electronic delivery |
| Promotion | Advertising, PR, communications |
| People | Employees, customer-facing staff, customers |
| Process | Service-delivery flow, queueing, automation |
| Physical evidence | Facilities, signage, branding cues |
64.4 Service Quality — SERVQUAL
Parasuraman, Zeithaml and Berry’s SERVQUAL model (1988) is the most-tested service-quality framework (parasuraman1988?). Five dimensions:
TipSERVQUAL — Five Dimensions
| Dimension | What it captures |
|---|---|
| Reliability | Ability to perform the promised service dependably and accurately |
| Assurance | Knowledge and courtesy of employees; ability to inspire trust |
| Tangibles | Appearance of facilities, equipment, personnel, communication materials |
| Empathy | Caring, individualised attention |
| Responsiveness | Willingness to help customers and provide prompt service |
The mnemonic — RATER.
64.4.1 The GAP Model
PZB’s GAP model identifies five gaps between expected and perceived service (parasuraman1985?):
TipThe Five Service-Quality Gaps
| Gap | What it is |
|---|---|
| Gap 1 (Knowledge) | Between customer expectation and management’s perception of expectation |
| Gap 2 (Standards / Design) | Between management’s perception and service quality specifications |
| Gap 3 (Delivery) | Between specifications and actual service delivery |
| Gap 4 (Communication) | Between actual delivery and what is communicated |
| Gap 5 (Customer / Service) | Between expected and perceived service (Gaps 1–4 cause this) |
64.5 Service Process and the Service Blueprint
A service blueprint (Lynn Shostack, 1984) maps the service process showing customer actions, onstage and backstage employee actions, support processes, and physical evidence — separated by the line of interaction, line of visibility and line of internal interaction (shostack1984?).
64.6 Service Recovery
A service failure is any service that falls below customer expectations. Service recovery is the systematic effort to retain and rebuild relationships after a failure. The service-recovery paradox — well-handled recoveries can produce higher satisfaction than if the failure had not occurred — is the hopeful corollary.
64.7 Demand Capacity Management
Because services are perishable, balancing capacity and demand is central. Common levers:
TipDemand-Side and Supply-Side Levers
| Side | Lever |
|---|---|
| Demand | Differential pricing, reservations, communication, complementary services |
| Supply | Cross-train employees, part-time staff, customer participation, share capacity |
64.8 Holistic Marketing for Services
Three forms of marketing required for services (kotlerkeller2022?):
TipThree Marketings of Services
| Marketing | Between | Concerned with |
|---|---|---|
| External | Firm and customer | Marketing the offer |
| Internal | Firm and employees | Training, motivating, equipping employees |
| Interactive | Employees and customers | Quality of the service encounter |
64.9 Practice Questions
Q 01
IHIP
Easy
The four classical characteristics of services are summarised by the acronym:
View solution
Correct Option: B
IHIP: Intangibility, Heterogeneity, Inseparability, Perishability.
Q 02
7 Ps
Easy
Which is one of the three additional Ps in the services marketing mix?
View solution
Correct Option: A
Booms & Bitner (1981) added People · Process · Physical evidence to the 4 Ps.
Q 03
SERVQUAL
Medium
Which is NOT one of the SERVQUAL dimensions?
View solution
Correct Option: C
RATER: Reliability · Assurance · Tangibles · Empathy · Responsiveness.
Q 04
GAP Model
Medium
In PZB's GAP model, "Gap 5" is between:
View solution
Correct Option: B
Gap 5 = customer-side gap between expected and perceived service. Gaps 1–4 cause Gap 5.
Q 05
Inseparability
Medium
"Production and consumption occur simultaneously" describes the service characteristic of:
View solution
Correct Option: C
Inseparability — services are produced and consumed at the same time. Customer is part of the production.
Q 06
Blueprint
Medium
The "service blueprint" was introduced by:
View solution
Correct Option: B
G. Lynn Shostack's 1984 HBR article. The blueprint maps customer actions, onstage / backstage employee actions, support processes and physical evidence.
Q 07
Service Recovery
Medium
The "service-recovery paradox" suggests that:
View solution
Correct Option: B
A well-handled recovery can leave the customer more satisfied than before — counter-intuitive but empirically supported in many service contexts.
Q 08
Three Marketings
Medium
Kotler's three marketings of services are:
View solution
Correct Option: A
Kotler: External (firm-customer), Internal (firm-employees), Interactive (employees-customers).
ImportantQuick recall
- Service = act / performance, intangible, no ownership transfer (Kotler).
- IHIP: Intangibility · Heterogeneity · Inseparability · Perishability.
- Services mix: 7 Ps (4 Ps + People · Process · Physical evidence) — Booms & Bitner (1981).
- SERVQUAL (PZB 1988) — five dimensions, mnemonic RATER: Reliability · Assurance · Tangibles · Empathy · Responsiveness.
- GAP model — Gaps 1–4 (provider-side) cause Gap 5 (customer-side gap between expected and perceived).
- Service blueprint (Shostack, 1984) — lines of interaction, visibility, internal interaction.
- Service-recovery paradox: well-handled recoveries can boost satisfaction.
- Three marketings: External · Internal · Interactive.
