Problem vs Symptom

Products fail when teams solve what they can see instead of what is actually causing it.

Teams spend months solving the wrong problem.

Scenario

A food delivery app’s daily active users dropped 12% over the last month.

What is the actual problem?

The distinction

Symptom vs problem

Symptom

What you observe. It tells you something is wrong, rarely why.

  • Orders dropped
  • Users are uninstalling
  • Engagement reduced
  • Watch time declined

Problem

The underlying reason causing the symptom. It explains the why.

  • Checkout became slower
  • Recommendations turned irrelevant
  • Pricing confused users
  • Onboarding became harder
The shift

How weak and strong thinking differ

Strong PMs investigate causes before proposing solutions.

Weak PM thinking

“Users aren’t opening the app enough. Let’s send more notifications.”

Strong PM thinking

“Why are users not returning? Where exactly is the friction? Did something change — is this a trust problem, a workflow problem, a value problem, or just a low-frequency product?”
In the wild

Real-world product patterns

Decisions users feel every day, read as a response to a visible symptom rather than the deeper problem.

Social · Instagram

The shift toward Reels

Observed symptom

TikTok's watch time and engagement were growing fast.

Product response

Instagram pushed Reels-first: full-screen feed, heavier recommendations, TikTok-style discovery.

Likely underlying problem

Instagram's core value — the friend and follow graph — may not be the behaviour that drives TikTok. Copying the format strained the thing users came for.

Commerce · Amazon

Search becoming ad-heavy

Observed symptom

The business needed stronger monetization and seller promotion.

Product response

Search and discovery filled with sponsored products, promoted listings, and ads inside results.

Likely underlying problem

The core shopping need is trustworthy, efficient discovery. Ad density competes directly with the ranking users rely on to find the best product fast.

Careers · LinkedIn Jobs

Notification pressure

Observed symptom

Users stop opening the app once an active job search ends.

Product response

More notifications — profile views, appearing in searches, new jobs, recruiters hiring.

Likely underlying problem

This may simply be a low-frequency product. People need it intensely during a search and rarely between. Pushing engagement makes it feel spammy without addressing that.

The method

How strong PMs investigate

  1. 01

    Symptom

    The visible, measurable thing that moved.

  2. 02

    Where it happens

    Which segments, cities, or funnel steps actually shifted.

  3. 03

    Break down the funnel

    Decompose the workflow to isolate the step that changed.

  4. 04

    Investigate causes

    Pricing, release, onboarding, trust, competition — what changed?

  5. 05

    Validate with data

    Test the leading explanation before committing a fix.

  6. 06

    Then solve

    Design the fix against the cause, not the signal.

Reflect

Think of a product feature you found annoying or unnecessary. What symptom was the team likely reacting to — and what deeper problem might it have missed?

Takeaway

Symptoms are visible. Problems are causal. Strong PMs don’t react to the metric that moved — they find what moved it.
