Chapter 2: Theoretical Schools of Relationship Management#

Where does a business relationship really live? It is not just a contract in a drawer or a name in a database. Over the past few decades, researchers across the world have looked at relationships from very different angles — through networks in industrial markets, through the idea that everything is a service, through trust in marketing channels, and through deep social ties in Asia. This chapter walks you through those five major schools of thought so that you can see the same puzzle from multiple sides.

The Big Picture#

No single theory can fully capture what makes a customer relationship work. Different schools emerged in different business cultures — some in heavy industry, some in services, some in tightly knit societies. Together, they give you a set of lenses: if you look at a relationship through only one lens, you miss important truths. Understanding all five helps you build relationship strategies that feel natural whether you are selling steel beams in Sweden, banking services in London, or building partnerships in Shanghai.

The IMP Group: Relationships as Interconnected Networks#

When you buy a raw material such as paper pulp, you probably do not just order from a catalogue and walk away. You depend on the supplier’s delivery schedule, you adapt your machines to their pulp grade, and over time you learn each other’s routines. That observation, studied deeply by the Industrial Marketing and Purchasing (IMP) Group, is the core idea of its thinking.

IMP researchers started in the 1970s by looking at business-to-business markets in Europe. Instead of seeing independent buyers and sellers, they saw webs of long-term relationships where companies were linked by three kinds of bonds.

Actor bonds: The personal and organisational connections between people in the two companies — trust, knowledge of each other’s strengths, and even friendship that builds over time.

Activity links: The way one firm’s operations become linked together with the other’s — for example, a manufacturer matches its production schedule with the supplier’s delivery calendar.

Resource ties: The physical, financial, and knowledge-based resources that two firms share or adapt to each other — such as a joint warehouse, co-developed technology, or a shared IT platform.

Think of a car maker and a seat manufacturer. The actor bonds mean that engineers from both sides meet regularly and know each other’s names. Activity links mean the seats are delivered in sequence just as cars move along the assembly line. Resource ties mean the car maker has invested in tooling owned by the supplier. The relationship is a tight web of mutual dependence, not a simple arm’s-length purchase.

This network view reminds us that you never manage a relationship in isolation. The car maker’s bond with the seat supplier affects its negotiations with the fabric maker; a change in one activity ripples through the whole net. IMP therefore focuses on managing positions in a network rather than optimising single transactions.

📝 Section Recap: The IMP school sees business relationships as networks of actor bonds, activity links, and resource ties that make firms interdependent, so strategy is about managing the whole web, not just one link.

The Nordic School: Service and the Logic of Relationships#

Imagine a hotel stay. The guest does not buy a bed for one night — she buys a good night’s sleep. The value is not in the room itself but in what it does for her. Nordic scholars in the 1980s and 1990s built an entire relationship philosophy around the idea that everything is a service.

The core insight of the Nordic School is service-dominant logic. In this view, customers do not buy products; they buy services that create value when used. Even a physical product like a drill is really a service for making holes. Value is created (or destroyed) when the customer uses the product in her own life — this is called value-in-use.

Service-dominant logic: A mindset where the provider offers promises of value, and the actual value emerges only when the customer uses those promises in her own context (using a tool, enjoying a meal, feeling safer).

Value-in-use: The real worth of an offering, measured not at the factory gate but at the moment the customer applies it to her daily life.

Because value is created together, the provider’s job is not just to push a finished item over the counter. The hotel helps the guest get a good sleep by offering a quiet room, a comfortable bed, and a wake-up call, but the guest brings her own preferences, her bedtime habits, and even her mood. The relationship is a continuous dialogue where both parties learn and adjust.

Nordic thinking also stresses that every interaction is a moment of truth — a chance to strengthen or weaken the customer’s trust. A single grumpy receptionist can undo months of relationship-building. Therefore, the whole organisation, not just the marketing department, is in the service business.

📝 Section Recap: The Nordic School shifts the focus from selling things to enabling value-in-use through service, where the customer and provider create value together in every interaction.

The Anglo-Australian School: Six Markets, One Relationship#

If you run a business, you might naturally focus only on your paying customers. But a group of British and Australian researchers in the 1990s argued that your customer relationships can only thrive if you also nurture five other groups of people. This is the six-markets model.

Picture a pizza chain. Its obvious market is the customer market — the people who buy the pizzas. But who recommends the chain? That is the referral market — existing customers, food bloggers, and even hotel concierges. Who influences whether people try the pizza? That is the influence market — journalists, nutrition influencers, and local food critics.

Then think about who makes the pizza and delivers it. The chain needs talented kitchen staff, so it must attract people from the recruitment market. It also depends on flour, cheese, and tomato suppliers, which form the supplier market. Finally, the chain’s own employees, franchisees, and partners constitute the internal market — if they are unhappy, the customer experience suffers.

Six-markets model: A framework that identifies six groups a firm must build relationships with: customers, referral sources, influence channels, potential recruits, suppliers, and internal stakeholders.

The Anglo-Australian school’s great contribution is broadening the definition of relationship management. It teaches that a customer’s glowing recommendation is as much a product of your relationship with your delivery riders (internal market) as it is of the pizza itself. A well-run business sees these markets as an interconnected system, not separate silos.

📝 Section Recap: The Anglo-Australian six-markets model expands relationship thinking beyond paying customers to include referrals, influencers, recruits, suppliers, and internal people, showing that all six impact the customer experience.

The North American School: Trust and Commitment as Foundation#

Why do some business partnerships last for decades while others collapse after a few transactions? According to the North American relationship marketing tradition, the answer comes down to two things: trust and commitment.

Trust means you believe your partner is reliable and will not take advantage of you. Commitment means you value the relationship enough to work through difficulties rather than walk away. These two factors form the heart of what is often called the commitment-trust theory.

Trust: Confidence in a partner’s reliability and integrity — you expect them to do what they say and not secretly prioritise their own benefit at your expense.

Commitment: A long-term orientation; a willingness to invest effort, money, or emotion into a relationship because you believe it is worth preserving.

What encourages trust and commitment? The theory points to several building blocks. First, relationship benefits: if the partnership provides superior value — lower costs, faster service, better information — you will want to keep it. Second, shared values: when both parties agree on what is important (honesty, quality, innovation), trust deepens. Third, communication: frequent, open, and meaningful exchanges reduce suspicion. Fourth, an absence of opportunistic behaviour: if you see your partner never exploiting you, trust grows.

The North American school puts these ideas into a clear causal chain. High trust and commitment lead to cooperation, which reduces conflict, which increases the willingness to stay in the relationship. It is a remarkably practical model: if you notice a partner losing trust, you can diagnose whether it is because they no longer see the benefits, perceive a values gap, or have stopped communicating.

📝 Section Recap: The North American school places trust and commitment at the centre of relationship strength, showing that these grow from mutual benefits, shared values, good communication, and honest behaviour.

The Asian Guanxi Approach: Social Bonds and Reciprocity#

So far we have talked about relationships as something built between companies. But in many parts of Asia, particularly in Chinese business culture, a relationship is first and foremost between people. The term guanxi captures this personal, long-term social bond.

Guanxi is not just networking. It is a web of mutual obligations, built over years, through acts of kindness, favours, and social rituals. Three key elements keep it alive.

Renqing: The deep sense of reciprocity and moral obligation to return a favour. If someone helps you, you carry an informal debt — you are expected to help them later, often without keeping strict score.

Mianzi: Face, or social standing and respect. Giving someone face means publicly respecting their status and reputation; losing face damages the relationship deeply.

Xinyong: Personal trustworthiness, but rooted in character rather than formal contracts. Your word and your reputation in the community matter more than any legal guarantee.

In a guanxi-based relationship, a businessperson might host a dinner long before any contract is discussed, send a thoughtful gift during a festival, or use a mutual friend as a go-between. These gestures are not empty formalities — they weave the social fabric that makes business flow smoothly. When problems arise, the parties rely on their personal bond to negotiate a solution instead of rushing to lawyers.

For non-Asian firms, this can be puzzling. A Western manager might see a dinner as a waste of time when the contract is ready to sign. But in guanxi logic, the dinner is the groundwork. Skipping the social bond is like building a house on sand.

📝 Section Recap: The Asian guanxi approach builds business relationships on personal trust, reciprocal favours (renqing), face (mianzi), and character-based trustworthiness (xinyong), making the social bond the foundation of commercial success.

Summary#

You have just toured five ways of thinking about customer relationships, each born from a different business soil. The IMP school shows how relationships are knots in a network; the Nordic school reframes everything as service and co-created value; the Anglo-Australian model reminds us to look beyond paying customers to five other critical markets; the North American school anchors everything in trust and commitment; and the Guanxi lens reveals the power of personal social bonds and reciprocity. No single viewpoint is the whole truth; wise managers learn to weave them together depending on the industry, culture, and moment. Now you have the lenses to see the rich fabric of any relationship you manage.
