Grade 6 Changing and Improving interview questions test whether you can lead useful change at scale, make space for ideas from other people and respond quickly when implementation starts to go wrong.
At this level, a strong answer should show the effect of the change on the organisation and the people using the service. The panel also needs to see how you handled challenge and whether you considered technology, accessibility or other practical impacts where relevant.

What Changing and Improving means at Grade 6
💡 Encourage ideas: create opportunities for colleagues and stakeholders to propose improvements.
🗣️ Make challenge safe: people should be able to question existing approaches without being dismissed.
📈 Show the value: explain what the change will improve for the business or service.
💻 Consider technology: understand where digital tools can improve public-service delivery.
♿ Assess the impact: consider culture, morale and accessibility rather than treating implementation as purely technical.
⚠️ Act on warning signs: identify problems early and adjust the change before they become larger failures.
🏛️ Challenge upwards: give constructive challenge to senior leaders when a proposal creates unnecessary risk.
Grade 6 Changing and Improving interview questions
❓ Tell us about a time you led a significant improvement to a service or way of working.
❓ Describe a time you challenged an established process and introduced a better approach.
❓ Give an example of when you created space for other people to propose improvements.
❓ Tell us about a change that started to go wrong. What did you do?
❓ Describe a time you introduced innovation while working with limited resources.
❓ Give an example of when you had to challenge senior management about a proposed change.
How to structure your answer
💭 Belief: briefly explain what makes change useful rather than change for its own sake.
📍 Situation: describe the problem with the existing approach and why it mattered.
🎯 Task: make your leadership responsibility clear.
🛠️ Action: focus on how you gathered ideas, designed the change and handled impact or resistance.
📈 Result: show a measurable or observable improvement and what happened after implementation.
Example answer: introducing improvement under constraint
Belief: I believe improvement is most useful when it removes repeat effort or risk and when the people doing the work have a genuine role in shaping the change.
Situation: I led a live digital service where demand was increasing while our delivery capacity was being reduced. A growing amount of specialist time was being spent on manual assurance checks and repeat incidents.
Task: I needed to improve resilience without relying on new funding or increasing workload for an already stretched team.
Action: I held short improvement sessions with engineers and service staff and asked them to identify the work that created the most repeat effort. Several people suggested automating a group of routine validation checks, although earlier proposals had stalled because of concerns about risk.
I asked the team to design a small pilot using tools we already owned. We agreed which checks were safe to automate and kept manual review for exceptions. I involved operations staff in designing the alerts so the output made sense to the people responding to them.
When early feedback showed one alert was generating unnecessary noise, I paused that part of the pilot and asked the team to refine the threshold. I explained the results to senior leaders and challenged the assumption that improvement required a new technology budget.
Result: The final checks reduced repeat manual activity and gave the team earlier warning of service problems. Specialist time was released for higher-risk work and the pilot became the basis for further automation.
What interviewers need to hear
✅ Why the existing approach needed to change.
✅ How other people were encouraged to contribute ideas or challenge you.
✅ How you considered users and the people affected by implementation.
✅ What you did when evidence showed part of the change needed adjusting.
✅ What value the final change created.
Common mistakes
❌ Describing a change that was imposed on you rather than one you shaped or led.
❌ Focusing on the new process while saying little about people or implementation.
❌ Calling something innovative simply because it used technology.
❌ Ignoring early signs that the change was causing new problems.

Choosing your strongest interview example
Use a change where you had enough influence to shape both the design and the implementation. An example where somebody else handed you a finished plan can still work, but you need a clear point where your judgement materially improved it.
🔧 A service redesign that reduced repeated failure or manual effort.
💻 A digital improvement where technology was selected because it solved a defined user or delivery problem.
📋 A policy or process simplification shaped by feedback from users or delivery teams.
⚠️ A change where early data showed the original approach needed correcting.
🏛️ A senior proposal you challenged because the implementation risk outweighed the expected benefit.
Follow-up questions to practise
❓ How did you know the existing approach needed to change?
❓ What resistance did you face and how did you respond?
❓ What did you do with feedback that challenged your preferred solution?
❓ How did you measure whether the change was working?
❓ What would you change if you implemented it again?
