Most teams think the hardest part of heuristic evaluation is spotting issues, but honestly, the hardest part is deciding what's worth writing down.

If you document every tiny imperfection, your findings starts feeling nitpicky, and once that happens, the evaluation becomes exhausting to read and less likely to drive change.

So before we talk about formats like spreadsheets, workbooks, and slides, I want to zoom in on what really matters, the core elements that make a heuristic evaluation useful in the first place.

And the first one is the finding itself.

A good finding is a clear description of what you observed and why it's a usability problem.

Your job isn't to critique the design or jump straight to solutions.

It's to describe what happened and explain why it creates confusion or risks for users.

For example, a weak version might say, "A spinning indicator does not give sufficient status." That's an opinion, but it doesn't explain the situation or the impact.

A stronger version would say, "The spinning indicator runs for more than 15 seconds without providing additional information.

For longer processes, users need clearer feedback, such as a progress bar, to understand what's happening.

This violates visibility of system status." Now we have context, we have impact, and we've tied it back to the heuristic.

Here's a key insight I want you to remember.

A useful heuristic evaluation isn't the one with the most findings. It's the one with the most meaningful findings.

So when you're documenting issues, focus on the problems that have the greatest impact on the user experience.

Don't force yourself to capture every minor annoyance.

Those small stuff lists can weaken your evaluation because they dilute the most important problems.

Let me show you what I mean with a simple example.

Imagine I'm looking at the FamilyDoctor.org website, and I'm focusing on the heuristic aesthetic and minimalist design.

I notice three potential issues.

One, showing both created by and reviewed by feels excessive.

Two, a generic icon next to the reviewed by name doesn't add meaningful value. And three, the headings are disproportionately large and wrap awkwardly, which makes them harder to read.

Now, the question isn't whether these are issues.

The question is, which ones are worth documenting?

In this case, I would prioritize heading size because it directly affects scannability.

That's a clear usability impact, and it's a strong violation of aesthetic and minimalist design, because the visual emphasis is being added in a way that actively interferes with understanding.

The other two observations feel more like nuisances.

They might be slightly distracting, but they don't meaningfully interfere with task completion.

So in practice, I might leave them out, or at least choose not to spend my team's attention on them.

The goal of documentation isn't to prove you noticed everything. It's to capture the issues that matter enough to act on.

Thank you for joining this preview of Heuristic Evaluations: How to Plan, Conduct, and Report Results, our self-paced course that walks you through what heuristic evaluations are and how they can help you uncover design flaws early.

This is a comprehensive step-by-step class that covers the full process, from planning the evaluation to running it effectively and documenting and communicating results your team can act on.

You'll learn a practical approach for running heuristic evaluations, so you and your team can make informed decisions in a collaborative and efficient way.

And because this is an NN/G self-paced course, you're in complete control. You set the pace, and you can start and pause whenever you like to fit the learning into your schedule.

通常の速度で一文ずつシャドーイングし、話し手のリズムに合うまで繰り返します。
自分の声を録音して元の音声と比べます。interfere, indicator, aestheticなどの単語に特に注意しましょう。

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
