The Foundation · Term 00
Service Design.

The practice of planning and organizing people, infrastructure, communication, and material components to improve service quality and interaction between service provider and customers.

Service design makes invisible processes visible, so they can be analyzed, improved, and optimized for both customer experience and operational efficiency. It is less a single deliverable than a way of seeing: the discipline of treating a service as a designed object, with edges, parts, and decisions that can be drawn, debated, and reworked.

Service blueprint across four stages — Discover, Consider, Purchase, Support — with lanes for customer, front stage, back stage and support. A line of interaction sits below the customer row; a dashed line of visibility marks everything beneath it as invisible to the customer.

A SERVICE BLUEPRINT AT A GLANCE

Section I Mapping & Frameworks 8 terms
Service Blueprint

A diagram visualizing the relationships between service components, tied to customer touchpoints. The single most useful artifact for surfacing hidden hand-offs and dependencies.

Service blueprint anatomy: four stacked lanes labelled Customer, Front Stage, Back Stage and Support. A solid line of interaction sits below the customer row, and a dashed line of visibility separates front stage from back stage.
Example

Horizontal chart showing customer actions, employee tasks, and supporting systems at each stage of the journey.

Customer Journey

The complete sequence of experiences a customer goes through when interacting with a service.

Customer journey shown as five connected points along an arrow: Search, Review, Book, Arrive, Check-out.
Example

Search → Reviews → Book → Arrive → Check out.

Service Stages

The time-based phases of customer experience, from awareness through post-experience.

Example

Discovery → Research → Purchase → Delivery → Support → Renewal.

Touchpoint

Any point of interaction between a customer and the service.

Example

Website; email; phone call; physical location; social media; app.

Touchpoint Mapping

Identifying and documenting all points where customers interact with your service.

Example

Listing every channel: Instagram ad → Website → Email → Store visit.

Channel

The medium through which a customer interacts with a service or receives value.

Example

Mobile app; in-store; phone; website; social DM.

Omnichannel

Service delivery across multiple integrated channels with seamless transitions.

Example

Start on app, continue on desktop, pick up in-store.

Service Ecosystem

The full network of people, organizations, tech, and resources that make a service possible.

Example

A clinic visit: patient, clinic, insurer, lab, pharmacy.

Section II Customer Understanding 8 terms
Persona

A fictional character representing a key customer segment, built from real research. Personas keep teams designing for someone specific instead of an abstract average.

Persona card for “Busy Beth”, a 38-year-old working parent who is mobile-first and shops between meetings. Tagged time-poor, value-driven and mobile-first, with the goal “Get the kids’ gear and get back to work.”
Example

"Busy Beth": working parent, values speed, shops on mobile during her commute.

Empathy Map

A tool for capturing what a customer says, thinks, does, and feels, to build deeper understanding.

Empathy map split into four quadrants. Says: “Why is this so slow?” Thinks: “I just want it done…” Does: abandons cart, retries. Feels: frustrated, tired.
Example

A four-quadrant canvas filled in from user interviews and observation.

Emotional Journey

A mapping of customer feelings and emotional states throughout their experience.

Emotional journey plotted as a curve: starting neutral, rising to excited, dropping to a frustrated low point, climbing sharply to relieved, then settling at calm.
Example

Anxious → Excited → Frustrated → Relieved → Calm.

Pain Point

A specific problem or frustration customers experience during their journey.

Example

Confusing checkout flow; unclear pricing; no order tracking.

Moment of Truth

A critical interaction point that significantly impacts customer perception.

Example

First impression entering a store; a support agent's initial response.

User Story

A short description of a feature or experience from the customer's perspective.

Example

"As a new client, I want a checklist so I know what to expect."

Co-Creation

Involving customers or stakeholders directly in designing the service experience.

Example

Inviting beta users to shape features; participatory workshops.

Desirability

Whether customers actually want the service, one leg of viability and feasibility.

Example

Validating demand before building; confirming the problem is real.

Section III Stages & Structure 8 terms
Line of Visibility

Separates front stage (what customers see) from back stage (hidden operations). Drawing the line forces a team to ask: what does the customer actually witness right now?

A dashed line of visibility dividing two bands. Above it, the visible front stage: customer, storefront, barista and receipt. Below it, the invisible back stage: inventory, schedule, suppliers, training and point of sale.
Example

Barista makes coffee (visible) | Manager orders supplies (invisible).

Front Stage

Customer-facing aspects of service delivery that are visible and experienced directly.

Example

Sales floor; customer service chat; website interface; reception desk.

Back Stage

Internal operations and employee actions invisible to customers but essential for service delivery.

Example

Kitchen in a restaurant; warehouse fulfillment; payment processing.

Line of Interaction

Separates customer actions from service-provider actions in a blueprint.

Example

Customer clicks "Submit" (above) → System processes order (below).

Swimlane

A horizontal row in a service blueprint representing a specific actor or system layer.

Example

Customer row; front-stage staff row; back-stage ops row; tech row.

Support Processes

Technology, systems, policies, and infrastructure enabling service operations.

Example

CRM database; payment gateway; inventory system.

Physical Evidence

Tangible or digital artifacts customers encounter during service delivery.

Example

Website design; signage; packaging; receipts; branded emails.

Handoff

The transfer of responsibility between people, departments, or systems.

Example

Sales → Onboarding; Online order → Warehouse → Shipping.

Section IV Process & Practice 8 terms
Double Diamond

A design process framework with two phases: discovering the right problem, then developing the right solution. Each diamond is a diverge-then-converge move.

The double diamond: a problem diamond and a solution diamond above four phases — Discover (diverge), Define (converge), Develop (diverge), Deliver (converge) — along an arrow running from start to delivery.
Example

Phase 1: research and insight gathering. Phase 2: ideation and delivery.

How Might We HMW

A reframing technique that turns problems into open-ended design opportunities.

Example

"Customers are confused at checkout" → "How might we make checkout feel effortless?"

Prototype

An early model of a service concept used to test ideas before full development.

Example

Paper mockup of a new intake form; role-played service walkthrough.

Decision Gate

A point where customers make a choice that affects their subsequent path through the service.

Example

Choosing delivery vs. pickup; selecting premium vs. basic plan.

Recovery Plan

A predefined process for responding when a service failure occurs.

Example

A script for handling missed appointments; a refund policy for delayed delivery.

Quality Checkpoint

A verification moment to ensure service standards are met before proceeding.

Example

Manager approves refund; QA reviews order before shipping.

Fail Point

A specific location in the service where things commonly go wrong.

Example

Payment gateway timeout; missed reminder; long wait times.

Feedback Loop

A mechanism for capturing customer input and using it to improve service design.

Example

Post-service survey; review requests; customer advisory boards.

Section V Measurement & Strategy 8 terms
Stakeholder Map

A visual diagram of everyone who has a role in or is affected by a service, arranged by influence, proximity, or interest. Reveals dependencies that pure org charts hide.

Example

Founders, staff, clients, vendors, and partners mapped in concentric rings, closest first.

Key Performance Indicator KPI

A measurable value demonstrating how effectively a service achieves its objectives.

Example

Net Promoter Score; average resolution time; conversion rate.

Service Level Agreement SLA

A commitment defining expected service quality, including response times.

Example

24-hour email response; 99.9% uptime; 30-day refund policy.

Net Promoter Score NPS

A loyalty metric based on customers' likelihood to recommend a service, scored 0–10.

Example

9–10 = Promoter; 7–8 = Passive; 0–6 = Detractor.

Customer Effort Score CES

A measure of how much work a customer must do to get an issue resolved or need met.

Example

Rating how easy it was to return a product on a 1–7 scale.

Value Proposition

The clear statement of how a service solves a problem and why customers should choose it.

Example

"We turn invisible team problems into measurable results."

Intangible Asset
