Questions and answers
Plain, complete answers to the questions people actually ask about continuous improvement: what the tools are, how to run them, and how to make change stick. Each answer is written from Dave O'Riordan's book, Continuous Improvement in the Workplace, and from ADX's own tools and course. For questions about ADX itself, prices and access codes, see the FAQ instead.
Foundations
What is continuous improvement?
Continuous improvement is a philosophy, not a programme or a set of tools.
What is the difference between continuous improvement and a one-off improvement project?
A one-off project has a finish line: fix this problem, install this system, then stop.
Why does continuous improvement fail when it's run as a program instead of a philosophy?
A programme can be launched, mandated and finished, so people wait for it to pass.
What are the "Big Three" simple tools to start continuous improvement?
The Big Three in Chapter 1 are Kaizen, Lean and Six Sigma.
How do I start continuous improvement in a small business?
Start with one small thing, not a programme.
What is kaizen?
Kaizen is a Japanese word for changing something for the better.
What is Lean?
Lean is a method focused on maximising customer value while minimising waste.
What is Six Sigma?
Six Sigma is a disciplined, data-driven method for eliminating defects and variability in a process.
What's the difference between Lean, Six Sigma, and continuous improvement?
Continuous improvement is the wider philosophy: the ongoing pursuit of better by everyone.
Can continuous improvement work outside manufacturing?
Yes.
What mindset shift does continuous improvement require?
The shift is from believing improvement is impossible to believing it is possible and necessary.
What is waste in a process?
In Lean thinking, waste is anything that consumes resources without adding value for the end customer.
What are the eight wastes?
The eight wastes are defects, overproduction, waiting, non-utilized talent, transportation, inventory, motion and extra-processing.
How do I spot waste in an office process?
Pick the one waste you suspect is most common in your work and tally it for three days before trying to fix anything.
Communication
Why is communication called the oil of continuous improvement?
Because without it, the whole improvement system seizes up.
What is a huddle board, and how do I set one up?
A huddle board is a visual management board that puts how the work stands where the whole team can see it, instead of leaving it in individual heads or…
How do I run a daily team huddle?
A daily huddle is a short, high-energy stand-up meeting, at the same time each day, lasting no more than 15 minutes.
What is SBAR, and how do I use it in an email?
SBAR is a structured way to communicate a situation clearly: Situation, Background, Assessment, Recommendation.
How do I create a culture where people speak up about problems?
Build trust through transparency, then actively invite dissent.
What are the three modes of communication in a team?
The three modes in Chapter 2 are verbal, non-verbal and written communication.
What is intentional silence, and why would a leader use it?
Intentional silence, which Chapter 2 calls CI-Lence, is a leader deliberately holding a pause after asking a thoughtful question, instead of rescuing the room.
What does an SBAR message look like?
An SBAR message has four short parts: the situation in one sentence, the background that explains it, your assessment of what is going on, and a specific…
What goes on a huddle board?
A good huddle board has four sections: celebrations, key performance indicators shown as trends, action items with a parking lot, and team updates.
Why do daily huddles fail, and how do I fix ours?
Huddles fail when they turn into long status meetings, try to solve complex problems on the spot, lose their board, or raise obstacles nobody follows up.
How do I write an email that gets a decision?
Structure it like an SBAR: a subject line that states the issue, one sentence of situation, the background the reader needs, your assessment, and a…
Seeing Problems
What is a gemba walk (a "go and see"), and how do I do one?
A gemba walk means going to where work really happens and watching it yourself, instead of judging it from meeting room reports.
How do I run a 5 Whys analysis?
Write down one specific problem, then ask why it happened.
When should I stop asking "why?" in a 5 Whys?
Stop when you reach the true root cause: an underlying, often systemic, cause that you can fix so the problem stops recurring.
What is a fishbone (Ishikawa) diagram, and when do I use one?
A fishbone diagram is a visual map of every possible cause of one problem, grouped into categories on a diagram shaped like a fish skeleton.
What's the difference between a symptom and a root cause?
A symptom is the visible sign that something is wrong: the late delivery, the complaint, the queue.
What is root cause analysis?
Root cause analysis is a methodical way of getting underneath a problem to its true causes, rather than fixing whatever showed up on the surface.
Should I use a 5 Whys or a fishbone diagram?
The 5 Whys fits a problem with one traceable chain of causes, where the aim is to drill down quickly.
What is process mapping, and how do I map a process?
Process mapping means drawing a process as a visual flowchart from start to finish, so the work becomes visible to everyone involved.
What is the voice of the customer, and how do I capture it?
The voice of the customer is what the people you serve actually expect, prefer, and dislike, gathered and acted on systematically rather than guessed at.
How do I decide which problem to solve first?
Plot each problem on an Impact vs.
What is a meeting "parking lot," and how do I use one?
A parking lot is a visible, designated space in a meeting, usually a corner of the whiteboard or a flip chart, where off-topic ideas and issues are written…
How do I get past "that's how we've always done it"?
Do not argue with the phrase.

Ask open questions about the work itself: what are you working on, what is getting in your way, where does this process break down, and what would you fix…
What are the most common gemba walk mistakes?
The common mistakes are treating the walk as an inspection, arriving with fixes already decided, going only when something has gone wrong, relying on reports…
How do I run a fishbone session with my team?
Write the problem as the fish's head, draw the six standard cause categories as the main bones (people, method, machine, materials, measurement,…
What is psychological safety, and why does improvement depend on it?
Psychological safety is the shared belief that you can name a problem, ask a question or admit a mistake without being punished or embarrassed for it.
Solutions

A rapid improvement event, sometimes called a kaizen event, is a focused sprint of typically three to five days in which a cross-functional team tackles one…
What is the PDCA cycle, and how do I run one?
PDCA is a repeating four-step loop for testing change: Plan a change and predict its result, Do it on a small scale, Check what actually happened against the…
How do I involve frontline staff in solving problems?
Start from the book's central lesson: the people closest to the work know the work best, so lasting solutions rarely come from the top down.
How do I pilot a solution before rolling it out?
Pilot inside a PDCA cycle.
How do I run a small improvement experiment this week?
Pick one small, nagging frustration, ask why it happens until you have a plausible cause, then test one tiny change through a single PDCA cycle: state a…
DMAIC or PDCA: which cycle should I use?
Use PDCA for small, quick tests of a change you can check within days.
What happens in each phase of DMAIC?
Define the problem and what success looks like, Measure the current process to get a baseline, Analyze the data for root causes, Improve by testing and…
What does a PDCA cycle look like in practice?

What is analysis paralysis, and how do I break it?
Analysis paralysis is drowning in data about a problem while never testing a fix.
How do I give my team permission to just do it?
Say explicitly which small, low-risk fixes need no approval, set a modest spend limit people can commit themselves, and protect anyone whose quick fix misfires.
Measurement
What is a KPI, and how do I choose the right ones?
A KPI is a Key Performance Indicator: a number tied directly to a strategic objective, not just any measure of activity.
"What gets measured gets managed": is that actually true?
Partly.
How do I make performance visible to my whole team?
Use a huddle board: a simple board in the team's workspace, updated daily, showing celebrations, a small number of KPIs with trend charts, and a parking lot…
What is a feedback loop, and why does it matter?
A feedback loop is a cycle: make a change, track the results, learn from them, and adjust your approach, then repeat.
Why do improvements fade after a few months, and how do I stop it?
Improvements fade when continuous improvement stays a separate programme instead of becoming how the team works every day.
How do I know whether an improvement actually worked?
Judge it against the KPI it was meant to move, tracked over time, not against effort or enthusiasm.
What's the difference between leading and lagging measures?
A lagging measure reports a result after it has happened: last month's defects, revenue, response times.
How often should a team review its metrics?
On two rhythms.
Why is celebrating too early dangerous?
Because an early number can flatter you while hiding the real result.
What are vanity metrics, and how do I avoid them?
Vanity metrics are numbers that flatter the team without reflecting the customer's outcome: clicks instead of completed tasks, activity instead of results.
What are the four tests of a good KPI?
A good KPI is relevant to a real goal, measurable with data you can actually get, actionable when it moves, and trackable over time with targets.
What is an operational review, and how do I run one?
An operational review is a regular, structured meeting that examines KPI trends and the effectiveness of improvement work, ideally scored against a rubric…
What is the Net Promoter Score, and should my team use it?

What is a CI maturity assessment, and how do I use one?
It is a structured scorecard of how well a team actually practises improvement, covering leadership, huddles, problem-solving and results, used to set an…
Leadership
What is the leader's role in continuous improvement?
The leader is the multiplier.

Keep the review fixed on the process: reconstruct what was supposed to happen and what did, dig for the system cause with tools like the 5 Whys, and write…
How do I get a sceptical manager on board with continuous improvement?
Do not sell tools; connect improvement to the goals the manager already owns, answer the why relentlessly, and prove it with one small measured win in their…
Pitfalls
What are the most common reasons continuous improvement fails?
Most failures are slow fades, not dramatic collapses.
How do I overcome resistance to change?
Do not fight resistance with more data.
What do I do when improvement work competes with day-to-day resources?
Protect the time and money for improvement, even when things get tight.
How do silos kill improvement, and how do I break them down?
Silos kill improvement because a customer's journey crosses departments, while improvement work stays inside them.

Continuous improvement is a long term game, and its gains often follow a short dip.
How do I keep an improvement process from becoming overcomplicated?
Tailor the process to the size of the problem.
What happens when a CI programme has no metrics?
Without metrics and feedback, people stop believing their work matters.
What is the knowledge gap in continuous improvement, and how do I close it?
The knowledge gap is expecting improvement results without investing in the skills to produce them: training reduced to a webinar and a PDF while workloads…
How does poor communication quietly kill an improvement effort?
It creates a vacuum, and the vacuum fills with fear, rumours and cynicism.
Why is complacency dangerous, and how do I fight it?
Complacency is success going quiet: a team that has hit its numbers stops asking what is next and becomes vulnerable at exactly the moment it feels safest.
Why do improvement efforts fade after a strong start?
They rarely collapse; they fade.
What do I do when a new tool flops with my team?

Can AI do continuous improvement for me?
No.
How do I build a digital idea box that people actually use?
Make submitting effortless, make ideas visible to colleagues, and prove that leaders act on them.
How should my organisation get ready for AI?
Start by assessing readiness, not by buying tools.
How do I get people to actually use a new tool after launch?
Involve the team in choosing and testing it, train hands-on with real work, adjust workloads during the learning curve, and measure outcomes rather than logins.
Critical Thinking
What is critical thinking at work?
Critical thinking at work is the disciplined art of asking the right questions.
Why is critical thinking a continuous improvement tool?
Because continuous improvement is solving the right problem and choosing a solution that holds up, and that is thinking work.
How do I build a culture of critical thinking?
A thinking culture is built by leaders modelling and reinforcing it daily, not by sending everyone to a training class.
How do I teach my team to ask better questions?
Teach a habit, then reinforce it in meetings.
What's the difference between critical thinking and being critical?
Chapter 9 does not draw this exact contrast as a named distinction, so this answer stays with its definition.
How do hidden assumptions hide the real problem?
An untested assumption decides what you look at, so you solve the visible symptom and miss the cause.
How do I challenge a decision without damaging trust?
Challenge the idea with questions and evidence, in the open, and be ready to change your own mind.
What is the Rule of Three for asking better questions?
Before solving anything, ask three questions: what is the real problem here, what evidence do we have, and what have we not considered?
What does a 5 Whys look like on a machine breakdown?
A factory machine kept jamming, the operator was blamed and put on notice, and a 5 Whys traced the cause through a worn part and a missed service to a…
How do I challenge an assumption my team treats as fact?
Ask for the evidence behind it and what the team has not considered, then test the smallest version of the doubt.
Engagement
How do I get my team engaged in improvement?
Engagement grows when improvement feels like something people want to join, not a mandate they have to endure.
What improvement games or activities work in a team session?
The activities the book describes are practical rather than elaborate: escape rooms, scavenger hunts, team trivia, problem-solving game nights, gamified…
Does gamifying improvement actually work?
In the book's hospital case study, yes.
How do I run an innovation day for my team?
Model it on the book's Innovation Carnival: split the organisation into cross-functional teams, give every team one full day and a budget to spend on a real…
How do I recognise and thank people for improvement ideas?
Use three layers: formal awards, regular spotlights, and immediate thanks.
How do I turn employee ideas into real impact?

The book's own examples, stated as it states them: variability in key performance indicators reduced by 30% after standardising best practice at a Fortune…
How does culture multiply improvement results?
The book calls culture a multiplier rather than an addition: tools and techniques only reach their potential in healthy soil.
