Defining a Specific Customer and Use Context

Why “Specific Customer + Use Context” Comes Before Building

Many beginner entrepreneurs describe their idea in a way that sounds exciting but is too broad to validate: “an app for fitness,” “a tool for small businesses,” or “a marketplace for creators.” The problem is not the ambition; the problem is that you cannot test demand, pricing, or messaging if you do not know exactly who the customer is and when/where they will use the solution.

Defining a specific customer and a use context means you can answer questions like: Who is the buyer? What situation triggers the need? What constraints exist (time, device, budget, approvals)? What does success look like in that moment? This chapter focuses on turning a vague audience into a concrete, testable target and turning a vague “use case” into a real scenario you can validate with interviews, landing pages, and small experiments.

Key Definitions

Specific Customer

A specific customer is a clearly described group of people (or organizations) that share relevant characteristics that affect buying and using your solution. “Relevant” means characteristics that change behavior: budget, authority, workflow, urgency, risk tolerance, tools they already use, and what they consider a good outcome.

Examples of vague vs specific:

• Vague: “Students”
• Specific: “First-year nursing students in community colleges who work part-time and study on mobile during commutes”
• Vague: “Small businesses”
• Specific: “Owner-operators of 1–5 person home cleaning services who schedule jobs via phone and struggle with last-minute cancellations”

Use Context

Use context is the situation in which the customer experiences the need and attempts to solve it. It includes the trigger event, environment, time pressure, device/channel, stakeholders, and constraints. Use context is what makes your product requirements real. A solution used “at a desk with time to compare options” is different from one used “on a job site with gloves on and no signal.”

Examples of use context:

• “Right after a client cancels within 2 hours of the appointment, the owner needs to fill the slot quickly.”
• “During monthly close, the finance manager must reconcile invoices across three systems before a deadline.”
• “On Sunday night, a parent plans the week and needs fast meal ideas that match allergies and a tight budget.”

What Changes When You Get Specific

Your messaging becomes testable

When you know who and when, you can write a headline that either resonates or fails quickly. “Stop losing revenue from last-minute cleaning cancellations” is testable; “Grow your business with scheduling” is not.

Your competitors become clearer

Your real competition is what the customer uses in that context today: spreadsheets, group chats, a friend’s recommendation, doing nothing, or a workaround. Specific context reveals these substitutes.

Your pricing and packaging become realistic

A hobbyist and a regulated professional may both “need organization,” but their willingness to pay, required features, and risk tolerance differ dramatically. Context reveals what the customer is protecting (time, money, reputation, compliance) and therefore what they might pay to reduce risk.

Your validation experiments become cheaper

With a narrow target, you can find people faster, ask better questions, and run small tests (ads, outreach, landing pages) with less spend and clearer signals.

Step-by-Step: Define a Specific Customer

Step 1: Start with a broad category, then narrow by “behavioral” filters

Begin with your broad audience, then narrow using filters that affect buying and usage. Useful filters include:

• Role: job title or responsibility (e.g., “office manager,” “freelance designer,” “parent who manages meals”)
• Experience level: beginner vs expert changes needs and language
• Frequency of the task: daily vs monthly tasks have different urgency
• Stakes: what happens if they fail (lost money, embarrassment, safety risk)
• Budget and willingness to pay: personal vs business spend, reimbursement, procurement
• Tools already used: Excel, WhatsApp, Shopify, QuickBooks, Notion, etc.
• Constraints: time, device, connectivity, approvals, regulations

Example: Suppose your idea is “a tool to help people track nutrition.” Narrowing might look like: “people tracking nutrition” → “people with dietary restrictions” → “parents managing a child’s allergies” → “parents of children with multiple allergies who plan meals weekly and shop at big-box stores.” Each narrowing step makes the customer easier to find and the use context clearer.

Step 2: Separate “user” from “buyer” (especially in B2B)

In many ideas, the person who uses the product is not the person who pays. If you ignore this, you may interview enthusiastic users who cannot buy, or you may pitch buyers who do not feel the pain directly.

• User: interacts with the solution day-to-day
• Buyer: controls budget or payment
• Champion: pushes adoption internally
• Gatekeeper: blocks or approves (IT, compliance, spouse, parent)

Example (B2B): A “shift scheduling tool” might be used by supervisors, paid for by the owner, and blocked by an accountant who dislikes subscription tools. Your customer definition should specify which person you are validating first (often the buyer or the person with the strongest pain and authority).

Step 3: Write a one-sentence customer definition

Use a template to force specificity:

[Customer type] who [does a recurring task] in [a specific environment] and struggles with [a specific friction] because [constraint].

Example: “Owner-operators of 1–5 person home cleaning services who schedule jobs by phone and struggle to refill last-minute cancellations because they don’t have a fast way to broadcast open slots to past clients.”

Step 4: Add 3–5 “qualifying criteria” for interviews and tests

Qualifying criteria help you avoid talking to the wrong people. They also make your validation data consistent.

Criteria examples:

• Has experienced the situation in the last 30 days
• Currently uses a workaround (spreadsheet, group chat, manual calls)
• Has authority to spend at least $X/month (or personally pays for tools)
• Does the task at least weekly
• Uses a specific platform/tool you plan to integrate with

Example: For the cleaning-service scenario, you might require: (1) owner-operated, (2) at least 10 recurring clients, (3) at least two cancellations per month, (4) uses SMS to communicate with clients, (5) personally decides on software purchases.

Step-by-Step: Define the Use Context

Step 1: Identify the trigger event

A trigger is what makes the customer stop and think, “I need to handle this now.” Without a trigger, the need stays abstract and low priority.

Common triggers:

• A deadline (tax filing, monthly reporting, school week planning)
• A failure (missed appointment, lost file, negative review)
• A change (new job, new baby, new regulation, new tool)
• A spike (sudden demand, seasonal rush)
• A cost increase (ads become expensive, supplier raises prices)

Example: “A client cancels within 2 hours” is a strong trigger; “I want more organized scheduling” is not.

Step 2: Map the “moment of use” with a simple scenario

Write a short narrative describing what happens before, during, and after the customer tries to solve the problem. Keep it grounded in reality.

Before: What happened? What are they trying to achieve? What’s at stake? What tools are open already? Who is involved?  During: What steps do they take? Where do they get stuck? What do they do instead?  After: How do they know it worked? What is the cost if it didn’t?

Example scenario: “At 7:30am, the owner gets a text cancellation for a 10am cleaning. They have 20 minutes before starting another job. They open their contacts, scroll through past clients, and send a few texts. Some don’t respond. They post on a local Facebook group but it’s slow. By 9:30am, the slot is still empty, and they lose revenue.”

Step 3: Capture constraints that shape the solution

Constraints are not “nice-to-know”; they determine what is feasible and what will be adopted.

• Time: minutes vs hours available
• Attention: multitasking, stress, interruptions
• Environment: noisy, on-the-go, at a desk, in a store
• Device: mobile-only, shared computer, locked-down work laptop
• Connectivity: poor signal, offline needs
• Risk: fear of mistakes, privacy concerns, compliance
• Social factors: needs approval, fear of looking unprofessional

Example: If the owner is often driving between jobs, a desktop-only solution is a mismatch. If they fear spamming clients, they need controlled messaging and opt-in.

Step 4: Define the “success metric” in that context

Success should be measurable and tied to the moment of use. Avoid vague outcomes like “be more productive.”

Examples:

• Fill a canceled slot within 60 minutes
• Reduce time spent reconciling invoices from 4 hours to 1 hour
• Generate a compliant report without errors on the first attempt
• Plan five dinners in 15 minutes within budget and allergy constraints

Combine Customer + Context into a Testable Statement

Once you have both, combine them into a statement you can validate:

For [specific customer], when [trigger/context], they need to [job to be done] because [stakes/constraint], and they currently [workaround].

Example: “For owner-operators of small home cleaning services, when a client cancels within 2 hours, they need to refill the slot quickly because the day’s revenue depends on it, and they currently text past clients one-by-one and post in local groups.”

This statement is powerful because it tells you exactly who to interview, what moment to discuss, what alternatives to ask about, and what outcome to measure.

Practical Worksheet: Build a Customer-Context Profile

1) Customer Snapshot

• Customer type: (role, company size, life situation)
• Where to find them: (communities, workplaces, local groups, platforms)
• What they already use: (tools, services, habits)
• Buying power: (who pays, typical budget range, purchase frequency)
• Top constraints: (time, device, approvals, risk)

2) Context Snapshot

• Trigger event:
• Where they are:
• What time it happens:
• What they do first:
• Where it breaks down:
• Workaround:
• Success metric:

3) Validation Target

Pick one narrow segment and one context to validate first. You are not choosing your final market forever; you are choosing the fastest path to clear learning.

Rule of thumb: Choose the segment where (a) the trigger happens often, (b) the stakes are high, (c) the customer can pay, and (d) you can reach them easily.

Examples Across Different Types of Ideas

Example A: Consumer service

Vague idea: “A service that helps people find healthy meals.”

Specific customer: “Parents of children with multiple food allergies who cook at home most nights.”

Use context: “Sunday evening weekly planning, limited time, needs grocery list compatible with a specific store.”

Success metric: “Create a 5-dinner plan and shopping list in 15 minutes with zero allergen ingredients.”

Example B: B2B tool

Vague idea: “A tool for managing projects.”

Specific customer: “Small marketing agencies (3–10 people) delivering client work with freelancers.”

Use context: “Monday morning status update, juggling multiple client deadlines, needs quick view of who is blocked.”

Success metric: “Produce a client-ready status report in under 10 minutes without chasing updates.”

Example C: Marketplace

Vague idea: “A marketplace for tutors.”

Specific customer: “Parents of middle-school students who need math help before exams.”

Use context: “Two weeks before exam, evening search on mobile, needs availability within 48 hours.”

Success metric: “Book a qualified tutor for the right topic within 5 minutes.”

Common Mistakes and How to Fix Them

Mistake 1: Defining the customer by demographics only

Age and location can matter, but behavior and constraints usually matter more. “25–35 year olds” is not a buying behavior. Replace it with role, frequency, stakes, and current workaround.

Mistake 2: Choosing a segment you cannot reach

A perfect segment is useless if you cannot talk to them. If your target is “hospital administrators,” but you have no access, start with a reachable adjacent segment where the context is similar and you can learn faster.

Mistake 3: Mixing multiple contexts into one product description

“Helps you manage tasks at work and at home” usually means you have not chosen a primary context. Pick one moment of use to validate first. Later, you can expand.

Mistake 4: Ignoring the “switching cost” in the context

If the customer is in a high-pressure moment, they will not adopt something that requires setup, training, or data migration. Your context definition should reveal how much friction is acceptable. If the moment is urgent, you may need a lightweight solution (template, checklist, simple messaging) rather than a full platform.

Mini-Exercises to Make Your Definition Sharper

Exercise 1: The “Not For” List

Write who your idea is not for, based on constraints and context. This reduces scope and improves clarity.

• Not for customers who do the task less than once a month
• Not for customers who need enterprise compliance approvals
• Not for customers who refuse subscriptions

Exercise 2: The “Last Time” Test

For your chosen customer, ask: “When was the last time this happened?” If you cannot describe a recent instance, your context is too vague. A strong target can recall a specific recent moment.

Exercise 3: The “Five Whys” on Context

Take your trigger and ask “why does that matter?” five times to uncover stakes.

• Trigger: “Client cancels.” Why does it matter? “Lost revenue.” Why does that matter? “Can’t cover payroll.” Why? “Cash flow is tight.” Why? “Seasonal demand.” Why? “No buffer.”

This reveals that the real value might be “cash flow stability,” which changes messaging and pricing.

Interview Prompts Focused on Customer and Context

When you start talking to potential customers, your goal here is not to pitch; it is to confirm that your customer and context are real, frequent, and painful enough to prioritize. Use prompts that force concrete examples:

• “Tell me about the last time [trigger] happened. What did you do first?”
• “What tools did you use in that moment? Why those?”
• “What was the hardest part? Where did you get stuck?”
• “What did it cost you (time, money, stress, reputation)?”
• “Who else was involved or needed to approve something?”
• “If you could wave a magic wand and change one thing about that moment, what would it be?”
• “How often does this happen in a typical week/month?”

Notice these questions are anchored in a real moment (“last time”) and reveal constraints and workarounds. That is exactly what you need to define a testable customer and use context.

Deliverable: Your Customer-Context One-Pager

Create a one-page document you can use for validation experiments. Keep it short and specific.

• Customer: one-sentence definition
• Qualifying criteria: 3–5 bullets
• Trigger: one sentence
• Scenario: 3–5 sentences describing the moment
• Current workaround: 1–3 bullets
• Constraints: 3–5 bullets
• Success metric: one measurable outcome

This one-pager becomes the foundation for your next steps: writing a landing page that speaks to a specific moment, choosing where to find early adopters, and designing a simple test that measures whether the customer cares enough to take action.
