Who this is for: Product managers preparing for interviews, startup founders deciding which users to target first, and anyone struggling to prioritize between multiple user segments.

The problem it solves: You’ve identified 3–4 potential user types for your product, but when asked which one to focus on, you freeze. Should you pick the one with the biggest pain point? The most frequent users? The ones with the highest willingness to pay? This guide gives you a simple scoring system to make confident prioritization decisions—and explain your reasoning in interviews or strategy meetings.

Why Prioritization Is Hard (And Why Interviewers Care)

Most product managers fall into one of two traps when asked to prioritize user segments:

  1. The "All Users Matter" Trap: You list 3–4 user types and say, "All of these are important!" This is the fastest way to fail a PM interview. Interviewers don’t want a list—they want a decision.
  2. The "Gut Feeling" Trap: You pick a segment based on intuition but can’t explain why. Interviewers (and stakeholders) need to see your thought process, not just your conclusion.

Prioritization isn’t about being "right"—it’s about making a defensible choice and showing you understand trade-offs. This chapter gives you a framework to do exactly that.

The 3-Dimension Scoring System

To prioritize user segments, score each one on these three dimensions (1–5 scale, 5 = best):

| Dimension | Meaning | How to Score |

|-----------------|-------------------------------------------------------------------------|------------------------------------------------------------------------------|

| Pain | How severe is this user’s problem? | 1 = Mild annoyance, 5 = Critical blocker (e.g., "I can’t do my job without this") |

| Frequency | How often do they encounter this problem? | 1 = Rarely (e.g., once a year), 5 = Daily or multiple times per day |

| WTP/Reach | Willingness to pay or how easy they are to reach | 1 = No budget/very hard to reach, 5 = High budget/easy to reach (e.g., via ads) |

How to Use the Scores

  1. Score each segment on Pain, Frequency, and WTP/Reach.
  2. Add the scores (max = 15).
  3. Pick the highest-scoring segment—but don’t stop there.
  4. Explain your choice by comparing it to the others. The trade-offs matter more than the raw score.

Step-by-Step Example: Prioritizing for a Note-Taking App

Let’s say you’re building a note-taking app and have identified these user segments:

  1. Students (taking class notes)
  2. Developers (documenting code)
  3. Journalists (interview notes)
  4. Busy Executives (meeting notes)

Step 1: Score Each Segment

| Segment | Pain (1–5) | Frequency (1–5) | WTP/Reach (1–5) | Total |

|-----------------|------------|-----------------|-----------------|-------|

| Students | 4 | 5 | 2 | 11 |

| Developers | 3 | 4 | 3 | 10 |

| Journalists | 5 | 3 | 4 | 12 |

| Busy Executives | 4 | 3 | 5 | 12 |

Scoring Notes:

  • Students: High pain (losing notes = failing exams) and high frequency (daily note-taking), but low WTP (most students won’t pay for apps).
  • Developers: Moderate pain (losing code snippets is bad but not catastrophic) and frequency (daily, but not all day), with some WTP (many devs pay for tools).
  • Journalists: High pain (losing interview notes = career risk) but lower frequency (not daily for all journalists), with decent WTP (some expense budgets).
  • Busy Executives: High pain (forgetting meeting details = bad decisions) but lower frequency (not all meetings need notes), with high WTP (corporate budgets).

Step 2: Pick the Highest-Scoring Segment

Journalists and Busy Executives tie at 12. How do you choose?

Option 1: Journalists

  • Why? Higher pain (losing notes = losing trust with sources), and journalists are easier to reach (Twitter, niche forums, journalism schools).
  • Trade-offs: Lower frequency than students, but higher WTP than students.

Option 2: Busy Executives

  • Why? Highest WTP (corporate budgets), and pain is severe (bad decisions cost money).
  • Trade-offs: Harder to reach (gatekeepers, long sales cycles), and frequency is lower than students.

Which to pick? It depends on your goals:

  • If you want fast growth, pick Journalists (easier to reach, decent WTP).
  • If you want high revenue per user, pick Busy Executives (but expect slower adoption).

How to Explain Your Choice in an Interview

Interviewers don’t care which segment you pick—they care how you think. Here’s how to structure your answer:

1. State Your Choice

"I’d prioritize Journalists as the initial target segment."

2. Explain the Scores

"Journalists scored highest on pain (5) because losing interview notes can damage their reputation. They also have decent WTP (4) since some have expense budgets, and they’re relatively easy to reach through journalism communities. While students scored higher on frequency, their low WTP (2) makes them a riskier bet for monetization."

3. Acknowledge Trade-Offs

"I didn’t choose Busy Executives even though they have high WTP because they’re harder to reach and have lower frequency. Students are a great secondary segment, but their low WTP makes them less ideal for our first focus."
