Definition

According to Zeithaml, Bitner & Gremler (“Services Marketing”, 2018), “Services are deeds, processes, and performances provided or coproduced by one entity or person for another.”

Introduction

Unlike products you can touch or stock, services are experiences — created and consumed in real time. Their unique nature makes marketing them a balancing act between promise and performance.

Explanation

1️⃣ Intangibility – cannot be seen or touched before purchase (e.g., insurance).
2️⃣ Inseparability – production and consumption occur together (e.g., haircut).
3️⃣ Variability – service quality depends on who, when, and how it’s delivered.
4️⃣ Perishability – can’t be stored (e.g., empty airline seats = lost revenue).

Key Takeaways

Service quality depends on people and process.

Branding and reviews make the invisible tangible.

Demand management minimizes perishability.

Real-World Case

Singapore Airlines built its brand on exceptional in-flight service consistency, managing intangibility through staff training and premium experiences.
