Designing a survey sounds easy. A few questions, a few answers, and you’re done, right? As you may have already discovered by virtue of being here, it’s a lot harder than it looks.

Question wording, answer design, structure and user experience all play a major role in whether the data you collect is useful. This becomes even more critical when you’re gathering feedback on complex topics like employee engagement, workplace culture, wellbeing, leadership effectiveness or overall employee experience.

Poor survey design leads to low response rates, misleading results or incomplete insights. When that happens, organisations risk solving the wrong problems or missing important issues entirely. Good survey design, on the other hand, leads to clearer insights, more confident decision-making and actions that genuinely improve the employee experience.

Luckily for you, we have put together some practical tips to help you design internal surveys that consistently deliver high-quality data.

1. Start With the End Goal for the Data in Mind

Before writing a single question, be clear on what decision the survey is intended to support.

Ask yourself: What is the primary objective? What action will the results help us take? What information do we need right now?

One of the most common mistakes in survey design is trying to answer too many questions at once. Once you’ve identified your goal, avoid adding unrelated questions unless they’re directly connected to what you’re measuring.

2. Match Your Questions to Your Purpose

Question-and-answer design is where good data is won or lost.

The type of question you use should align with the type of information you need, and knowing your purpose upfront makes it much easier to choose the right format.

Multiple-choice questions are useful when you need a clear, structured answer.
Rating scales help measure sentiment and track trends over time.
Ranking questions reveal priorities.
Open-text responses provide context, suggestions and deeper insight.

If you need employees to select a single answer, don’t provide an open-text box. Likewise, if you’re looking for detailed suggestions, a simple yes/no won’t give you enough to work with. When question formats and survey goals don’t align, the result is often inconsistent, difficult-to-interpret data.

3. Think About Overall Structure

Balance matters across the survey as a whole, not just at the question level. The types of questions you include, how many you include, and the order they appear can all affect response quality and completion rates.

Open-ended questions can provide valuable insights, but more isn’t always better. Too many free-text questions lead to survey fatigue, lower completion rates and responses that are harder to analyse consistently over time.

As a general guide:

Use structured, easy-to-answer questions for the majority of the survey.
Limit open-text questions to one or two key areas.
Place longer feedback questions toward the end.
Include an “Other” or “Not Applicable” option where relevant, so respondents aren’t forced into an answer that doesn’t reflect their experience.

You can also pair a structured question with an optional follow-up comment where additional context would be valuable.

For example:

How satisfied are you with communication from leadership?

Very satisfied / Satisfied / Neutral / Dissatisfied / Very dissatisfied

Optional: Please share any context behind your answer.

This approach gives you measurable, trackable data while still allowing employees to elaborate if they choose.

4. Write Neutral, Unbiased Questions

If you want honest feedback, your questions need to be written neutrally. Even subtle wording can influence how people respond, and leading questions often produce artificially skewed results.

For example:

Biased: How great is our office layout?

Neutral: How satisfied or dissatisfied are you with the office layout?

The difference may seem small, but neutral wording encourages more balanced and reliable responses. The same principle applies to your answer options. You should provide a balanced scale of measurement with response options weighted equally across positive and negative sentiment.

5. Ask One Question at a Time

A common mistake is asking multiple questions within a single question, sometimes known as a double-barrelled question. These make responses difficult to interpret.

For example, avoid: How satisfied are you with your pay and workload?

An employee may be happy with one and dissatisfied with the other, making it impossible to know what their answer means. Instead, separate them into two distinct questions. The more specific the question, the more useful the data.

6. Provide Context and Timeframes to Questions

Without a clear timeframe, respondents may answer based on a single recent experience rather than their overall experience.

Adding timeframes creates consistency and makes results easier to compare across time and between employees or teams.

For example:

Unclear: How do you feel about communication at work?

Specific: During the past four weeks, how satisfied have you been with communication from your manager?

Specifying timeframes reduces ambiguity and prevents unusual one-off events from disproportionately influencing your results. Timeframes are particularly useful when measuring engagement, manager effectiveness, wellbeing, communication, workload and team collaboration.

7. Choose the Right Mix of Question Types

A well-designed survey usually combines several formats, but every question should have a clear purpose.

A useful reference:

Question Type	Best Used For
Multiple Choice	Easy analysis and categorisation
Rating Scales	Measuring sentiment and tracking trends
Ranking	Understanding priorities
Open Text	Gathering explanations, suggestions and context

If you’re unsure whether a question belongs in the survey, ask yourself: “What will I do with this information?” If you don’t have a clear answer, consider removing it.

Additionally, avoid asking questions about areas the business has no intention or ability to change. Doing so can create false expectations and reduce trust in future surveys. If you’re collecting employee feedback, there should be a clear purpose and consideration for how those insights will be used.

8. Keep It Short, Simple and Consistent

Employees are busy. If a survey feels long or confusing, participation and response quality will both suffer.

To improve completion rates:

Aim for under five minutes where possible.
Tell employees upfront how long the survey will take.
Use clear, straightforward language and avoid unnecessary jargon.
Keep instructions easy to follow.
Use consistent rating scales throughout. If one question uses 1 = Strongly Disagree and 5 = Strongly Agree, don’t reverse the scale later in the survey.

Consistency reduces effort for respondents and improves the reliability of your data.

9. Test Before You Launch

Before sending your survey to the wider organisation, test it first.

Review it from the respondent’s perspective and ask: Is anything confusing? Could any questions be interpreted differently than intended? Are there unnecessary or repetitive questions? Does it flow logically?

Better yet, ask a small group of colleagues to complete it and share feedback before you go live. A quick test can often surface issues that would otherwise affect the quality of your results.

A Few Examples: Common Mistakes and How to Fix Them

Employee Engagement

Poor: Do you enjoy working here?

Better: How likely are you to recommend this organisation as a workplace to friends or family?

Manager Communication

Poor: Does your manager communicate well?

Better: Over the past four weeks, how satisfied have you been with your manager’s communication?

Recognition

Poor: Do you feel supported and recognised?

Better (split into two):

Do you feel supported in your role?
Do you feel recognised for your contributions?

Final Thoughts

When you’re measuring something as important as employee experience, engagement or culture, survey design matters more than most people realise.

Good questions lead to good data. Good data leads to better decisions, which in turn creates better employee experiences.

Once you’ve gathered those insights, the next step is acting on them. Whether that’s improving workplace culture, introducing a new initiative like the Boost Employee Benefits programme, or finding other ways to recognise and reward your people. Quality data gives you the confidence to make meaningful changes.
