Ben Asks: What is the Pareto Principle?

Life can be completely chaotic. Understanding where our time, energy and resources go and use this information to our own benefit ourselves, could be the key to taking back control. Understanding the 80/20 law is a wonderful way to explain life in better detail.


Vilfredo Pareto is a hero of mine. He is a person that looked at the world and applied numbers to it. He found logic and rules in the chaos. He was an engineer. 

His most famous piece of work was his analysis of the distribution of wealth in Italy. He found that 20% of the people owned 80% of the land and therefore he could say the remaining 80% of the people owned only 20%. 

Now-a-days, the ‘80-20 rule’ is applied everywhere from finance, to engineering, to horticulture. It is well-known 80% of the sales will come from 20% of the clients, 80% of the defects in a production plant will occur on 20% of the products, 80% of the harvest will come from 20% of the land.

How does this help us in a chaotic life?  Well, how do we analyse ‘life’? A good starting point is to use this simple tool to show us how to be more savvy about the tasks we take on.


80/20 Energy Distribution

As a generalisation, we can say 80% of a given project will take 20% of the effort, therefore when we understand this, and when we reach the last 20% and we start to struggle. We can understand that it is completely normal. 

The higher effort required to finish a project is the reason why so many jobs end up half completed or the final detail work comes out at a lower quality standard than the rest. The energy to finish, as a generalisation, is so much greater – 60% higher in fact (80-20%), than the ‘normal’ energy required to start and roll through 80% of the project itself.  Knowing it will be a struggle, we can ensure we apply the correct strategy to cope. 

We act rather than react. 

Imagine you take a long drive with your partner to a new city for a weekend away. If we apply the Pareto Principle, we know that 80% of the journey will be easy. Requiring only 20% of the effort, the miles will flow under the vehicle as you waft along without a care in the world. That is, until you reach the final 20% of the journey. Strap in and hold on as this shit’s going to go down. 80% of the effort is going to be needed to get you through that city centre. The unfamiliar road signs, the crazy local drivers and the bonkers one way system is going to be taxing to deal with. 

However, knowing this in advance we can find a strategy to cope. We could plot the distance and find an appropriate place to take a break around 80% of the total journey. A good coffee break to sit down and accurately plan the final route to the destination. 

The interesting (albeit super nerdy)  thing about the principle is the extrapolation that comes with it. 

As 80% of the effort is on the last 20% of the project, in this last 20% of the activity, the first 80% of it will take 20% of the effort, then the final 20% of the final 20% will take 80% of the 80% of the effort. Confused?! Take a look at the graph for a more visual explanation.

Exponentially increasing, the closer you get to 100%, the more and more effort you need to finish. Finding the entrance to a city centre hotel car park is always the worst, right?


Overloaded at Work?

Have you ever sat down and thought “why is work so hard now-a-days?”. In the past it seemed like you could give your full attention to a project, the stress was lower and the end result was better. But now, it feels like you are just pounding out project after project? I know I do.

Maybe the Pareto Principle can help us understand this. Imagine all of the projects you ever completed at work were taken in series. One after the other after the other. Start a project, see it through until the end, finish and then start the next. The graph of effort against time would look like this. 

Periods of low effort and periods of high effort. After each high effort, a chance to relax and recuperate due to a period of low effort from the next project. A manageable system that works, right?

But if you are a manager of a company and you looked at this chart, would it not be so unreasonable to say that the workforce is only running at 20% of their effort for 80% of their time? Therefore, running projects in parallel should be completed. A reasonable assumption one might say for the overall productivity of the company.

That’s great until projects get delayed, high level periods start to overlap and of course the average overall maintained effort increases. 

With the prolonged increase in effort, comes the stress and fatigue that if not properly managed, can cause failure. 

In this instance, failure may mean not completing a project or turning the project in at a substandard level. While objectively, any rational human would judge you compassionately for having attempted to juggle multiple projects, in your mind, neither failure nor a lack of quality, is going to make you feel good.

Understanding this, could help realise why you are feeling exhausted, or why you need to sit down with your boss and ask for a time out. Without this understanding, without knowing your limits, you could be exposing yourself to the harm of a stressful environment for too long a period of time.


Managing your Time, Money and Resources

In production facilities, we use Pareto charts to look at defects. We need to know where the biggest problems are to fix, objectively, rather than with subjective opinions. Imagine we were in a car factory and every day a car came down the line with a smashed windscreen. In addition, 20 cars came down the line with a passenger door that didn’t open and 100 cars came down with a scratch in the paint work. Which is the problem to solve first?

Many people would think the windscreen first – it’s a terrible thing, right? Then the doors, followed by the paint as that’s an easy fix. That was my assumption when starting as a graduate engineer, but how wrong I was. First we would tackle the paint. 100 customers would complain of the scratch in the paintwork Vs. the one person with a smashed windscreen. Therefore to satisfy more people, we take the highest amount first.  

We need to assess the amount of potential complaints by the number of incidents. The way we can do this is with a ‘Pareto Chart’. The below chart shows an example for defects in a titanium facility. A classic Pareto Principle distribution showing a clearer picture of where to focus our attention. 

File:Pareto chart of titanium investment casting defects.svg

https://commons.wikimedia.org/wiki/File:Pareto_chart_of_titanium_investment_casting_defects.svg

Pareto charts are something I consider essential to my daily life. I use them everywhere. At work, at home and when trying to figure out a ‘why’.  Have you ever inputted your budget into a chart like this to see where your money goes? 

The same pattern will emerge. The highest is probably the mortgage, followed by the bills, then clothing, food, entertaining etc. How does this help you though? Well just like an engineer in a production plant trying to reduce defects to bring the total level down. When plotting your monthly budget into a Pareto Chart, it is easy to identify areas to save money. You look at the highest bar first and work your way down the chart to the bottom. 

To take another example, have you ever measured what you do during the day and plotted the times on a Pareto Chart? 

A typical day could be, wake up at 6am, lay in bed until 6:15. Get up, shower, have some breakfast and leave for work. Commute to work and slave away all day before returning home. Go for a run, prepare the evening meal, take a shower. Sit down to eat food, turn on the TV. At the end, brush your teeth and go to bed. Read for half an hour and sleep.

The data in a table format would be as follows.

ActivityTime
Sleep8
Wake up0.25 (quarter of an hour) 
Showering (morning and evening)0.5 (half an hour)
Breakfast0.25
Commuting (to and from)2
Work8
Running1
Evening Meal Prep1
TV2.25
Brushing teeth and going to bed0.25
Reading0.5
TOTAL24

And this data plotted as a bar chart.

What if we now move the chart to a Pareto style? We simply re-order the blocks to show the biggest on the left and the smallest on the right.

Now the results become quite interesting. If we were to look for things to reduce to allow us to have more free time, it becomes quite easy to see where our time is being wasted. 

How many people put ‘watching TV’ as a hobby on their CV do you think? The 3rd biggest usage of time in our days! Statisica.com reports for people aged 25-44, the average TV time per day was 2.75 hours, (just in case you thought my numbers were above average).

When I completed this task on myself to try and make my day more productive, it was a shock to realize where my time went – and I am pretty abnormal. I make sure I have eight hours in bed each night, most people only manage six to seven. If I wanted more time, to create more freedom, I knew where I could find it. Turning off the TV and investing some of that time to better myself… 

80% of the time above goes to working, commuting and sleeping activities. Therefore you only have 20% left for you. What would you like to do with it?

The Pareto Principle can be applied to almost anything to understand where your energy, time, money, resources etc are going. It can help you understand why you are burnt out. It can be a tool to show your manager that you need to cool it down a bit. It can be a guide to knowing when to take a break before you do that final push. 

Think about an area in your life you would like to understand and see how Pareto can help you. 

Let me know how you get on!

Ben Asks: Do you need to get debt free?

Money, it makes the world go round, but for the vast majority of us, we learn how to handle finances through trial and error—mistakes that can be super costly and affect our mental attitudes, relationships and future life plans.


By far the biggest change in my life has been my attitude towards money. I wasn’t given any real money advice by my parents. Neither was it on the curriculum in school or at university. Like most people, I had to figure it all out by myself. 

I distinctly remember the time it all went wrong. Aged 18, a friend in Canada and the words “just get a credit card, book the flights and pay it off later . . .”

I hadn’t been taught how to control my money, so I didn’t really stand a chance of becoming financially savvy when my parents, the banks, the car people, the house people etc. all wanted me to buy stuff now and pay for it all later. It was as standard and normal as an A4 piece of paper. 

The hardest realisation though, was the company I worked for, the people who paid me, dressed me and put food on the table each night actively, wanted me to have less, so that they could actually make more. 

When I realised that, I wanted, for want of a better expression, to stop the corporate bus and get off. In that singular moment, I knew the system was wrong. “Welcome to the real world, son” might be the reality, but that wasn’t a world I could live inside without some level of control, even if that is just something I’m telling myself.


What is the root cause of the problem?

Ask yourself the question – If you lost your job today, how many days can you live before you NEED money? 

Gobankingrates.com, a website dedicated to financial topics, estimated in 2019 around 69% of Americans had less than $1000 saved away in a bank account.

The BBC reported that in the UK, “A survey by the Money Advice Service has found that four in 10 adults…do not have £500 or more in savings. Another by ING bank suggests 28% of UK adults have nothing at all in the bank.”

And the Independent states that “More than quarter of UK households have no emergency savings…”

How did we end up in a situation where it’s common for all of us to live on the edge of financial disaster?

I have come to understand the game we are playing. It’s a game where we live in a world where everybody wants to make money. Simple, right? But this becomes quite tricky when we start to look at the companies and financial institutions closest to us. 

At work, unions have been demolished, equal pay is a touchy subject and satisfying the shareholder is now a priority subject for every CEO.

It is clear, the less we earn, the more we seem to borrow and the more the banks will make. Is this the darker side of capitalism?

The documentary ‘Saving Capitalism’ featuring Robert B. Reich, the former Secretary of Labor to then Clinton administration, paints a very vivid picture of the situation. “The simultaneous rise of both the working poor and non-working rich offers further evidence that earnings no longer correlate with effort.”

Robert B. Reich, Saving Capitalism: For the Many, Not the Few

It is recommended from articles such as ‘marketwatch.com’ amongst others, that by the time you are 35, you should have twice your salary saved away. 35!? I ask: why the topic of personal finances was not firmly placed between Maths and PE on a Tuesday morning with Mrs Smith? 

As you can see, the harsh reality is that nobody is out there fighting for you to look after or  make more money – therefore you really have to do this stuff yourself.


When booking those flights to Canada, I didn’t realise then, how that one decision I was about to make, would be so disastrous for the next fifteen years of my life. 

Young and on reflection, not so clever, I got the credit card and had a wild time for two weeks; skiing, driving around in a Mk1 Golf convertible, playing board games and drinking a few too many lemonades.  

Upon my return, I was greeted by the mountain of debt I’d racked up… Of course I had neither the money, nor the discipline to pay the credit card off at once. I set it to pay off the minimum monthly balance, high on memories of my Great Canadian Adventure. The years passed by, loans and credit cards were a staple of my financial diet and the initial £1500 holiday cost closer to £2,900 once compound interest was taken into account.  It didn’t stop there. Over the years, thousands of pounds of hard-earned money, washing away in a blur of social situations, material possessions and long-forgotten drunken memories. It’s harder when there’s nothing to show for it all, eh?  

Fast forward ten years to Ben, aged 28 and I found myself sitting in a room with a group of people being trained to sail around the world. There was a girl around my age; cute, blonde, Norwegian, who looked at me in a way that buckled my knees forever. Another guy, also around my age, was as smart as they come with a niceness factor through the roof. At that time I could only afford to pay to sail halfway around the world. But  these two people, around the same age as me were doing the WHOLE thing. I thought if they are doing it all, why can’t I? 

I sat in the back of the class, I opened up my bank’s website and I applied for a £30,000 loan for the balance of the rest of the journey. Within an hour it was approved and within a day I had the funds sitting in my account. It was that easy. It was so easy in fact it was scary.

Returning to land a year later from the race, with around £30,000 loan, around £7000 in credit cards and £3000 loan from my parents. No job, no assets, no nothing. I knew it was time to make a change. A sickening feeling arose, I was now a slave to that debt. Shackles are something very few of us would choose to wear. Yet this is what we do mentally when we are indebted. We are shackled to the whims of an economy that is not designed to work in our favour. Freedom felt a long way off. 


The interesting thing about the people I met on the race was how savvy everyone seemed to be with money. They all ‘knew’ the money game and they all thought I was completely crazy in my approach to life on credit—I think ‘delinquent’ is the official phrase. Upon asking my close friends for advice to get out of this situation, one friend, Ryan, said he could help me. Looking back, he changed my life in a way bigger than I ever thought was possible,  recommending a book which altered my view on the financial world forever. 

The book was Dave Ramsey’s ‘Total Money Makeover’.

The book discusses a foolproof plan to become debt-free. You first save a small emergency fund, so that you can cut up all your credit cards and not worry about needing them. Then you pay off all your debts, excluding the mortgage. Boost your emergency fund to 3-6 months, then start to do things for the future. 

I was so passionate about doing this that I jumped in head first and dragged my wife along with me. I distinctly remember sitting in a hotel in Stavanger reading the page on cutting up credit cards and I went for it. I asked the receptionist to borrow a pair of scissors and cut up my credit cards there and then. It was terrifying and freeing all at the same time. Like jumping out of a plane, I didn’t really know where I was heading and how this was going to turn out, but I knew it was exciting! I carried one piece of credit card in my wallet until recently as a constant reminder of the days gone by. 

Becoming debt-free and being like the people on the boat was my whole focus in life. I wanted to be as carefree as they were. If they lost their jobs, it wasn’t stressful. Some of them were there just taking a year off anyway, just for fun. Most could live for months on the same lifestyle without needing to go to the banks for a loan. They were making money each day by just having money stashed away in various accounts, funds and portfolios. “What was this wizardry?” I thought.  

Well the truth is, it’s no more magic than driving a car, riding a bike or making a delicious chocolate cake. It’s just learning what to do and having the discipline to do it right.  

You set up a Plan, Do, Check, Action Process, as we talked about in a previous blog here. And you just get to work. 

It took me over three years to become debt-free and five years to be in the position that I’m in now. I have no debts apart from the mortgage, I have a 6 month emergency fund saved away and when I get my paycheck, 15% of it goes straight towards my retirement. If everything stayed the same, although I’m working to shorten the time of course…I should be a millionaire by the time I retire.

I’m not going to sit here and say it was, and is, easy though. You have to actively turn your back on a “normal” life and walk your own road. It takes months to pay off credit cards and years to pay off the cars. In all this time, you have to say “no” to anything fancy or fun. There are times when you stare at yourself in the mirror, wearing the same T-shirt you’ve owned for 8 years and think, what am I doing? I’m in the prime of my life, living on less money than when I was a student. ‘Buy now, pay later’ indeed.

You see all your mates, in fancy cars, having fun and going on holiday and you are sat, inside, watching the TV again. Of course, you wonder if they’ve been more money-savvy or if that enjoyment comes at a price they’ll pay later.

Debt repayment is  a long, hard, boring game and one in which you know will only take as long as the discipline you put in. One night out, means £50 less to pay off the car, which may push you into another month of debt-free mission living. There was a reason our grandparents called it ‘The never-never’. 

But it’s not forever. And it isn’t ALL doom-and-gloom. Funnily enough, this road looks more like the roads our grandparents would walk. Valuing shared neighbourly socials where everyone brings a bit, rather than flamboyant stag dos in random European cities. We’re all living well beyond our means, encouraged by colourful marketing campaigns. This new path shuns much of that stuff, seeing it for what it really is. 

Sometimes getting out of debt is a case of finding another tribe. One where symbols of status and wealth are not the priority. But just like the water principle, you have to input energy to dramatically change your ways. Then, after the transformation happens, you can walk a new path to a much better future than before.


To end, I want to leave you with a final thought, who is richer?

Person A and Person B earn the same money. Person A, has no savings, drives a Porsche on a loan, has a vacation home on a mortgage, dresses in designer clothes, eats out regularly and takes nice vacations all on credit cards. The disposable income after all the expenses and interest payments is around £30 each month.

Person B, saves £300 each month, drives a Volkswagen Golf, rents a vacation home for a week at a time, pays cash, dresses sensibly, eats out rarely but still takes nice vacations. All paid on cash not credit. The disposable income of this person is around £1000 each month. 

If both people lost their jobs, had their houses flooded, or had an accident in the family which needed large hospital bills. Who is the wealthier person and how much chaos would each person have in their lives if something went wrong?

You should never judge a book by its cover and no situation is more true than that with money.

Ben Explains: Root Cause Analysis

All too often we get distracted dealing with the symptoms of our issues, rather than the root causes. Today we’ll discuss Root Cause Analysis and learn how to channel precious energy and time into making more progress. More progress equals more productivity.


Engineering can be defined as ‘The action of artfully bringing something about’. 

Maybe you’ve read a couple of posts, sat down at the table and thought, ‘right, time to get this **** sorted’. Then stalled, just as I did. Trying to solve the problem of ‘life’ is like trying to eat an adult elephant with a baby spoon, it’s hard! (Not that I would ever condone eating an elephant, but you get the visual: Big Thing, Tiny Tool).

Over the years, engineers have developed a number of  tips, tricks and techniques to ‘standardise’ the way we work to ensure we are the most efficient in our jobs. It’s ‘evolution over revolution’ because if someone has already done the hard work, then why reinvent the wheel?

As engineering covers such a wide range of topics, even our own personal, chaotic, lives can benefit from these  methods. Last week I discussed how engineering is about solving problems, so here is a tool to help you firstly define the problem, then for you to go about artfully solving it.


So what is the root cause of the problem? (This is a phrase I constantly come back to, as it’s vitally important in engineering.) 

We are all capable of solving problems. In fact, there is no better person to solve your problems but you. It is you who understands your life better than anyone else ever could. As intelligent beings, we have the power of the internet to ‘search and solve’ even the most problematic of everyday scenarios. Or at least find a crevice in some far-flung corner of the internet, where one or two others are experiencing the same problem as we are—solidarity is a great first step. A little self-belief doesn’t hurt either.

However, all too often, we recognise there’s a problem, then we panic. Distressed at the difficulty in which we find ourselves, we fog our brains, failing to clearly define what we need to focus upon, failing to convince ourselves we can handle it. 

We would never go to the mechanics workshop and say “it’s broken” without giving some hint as to where it was broken first. The bill for the mechanic to find the fault, in the myriad of components on an automobile, if not completely obvious, would be astronomical.  Sometimes then, we need to sit down, look at ourselves in the mirror and ask, what exactly has gone wrong?  

I’m struggling with my money. OK, but what exactly are you struggling with? Are you being paid too little, do you run out of money before the next pay cheque? Are your bills greater than your income? 

My side hustle is struggling. OK, but what exactly is the problem? Are your products selling? Is your advertising working? What feedback are you getting from the customers?

My relationship is on the rocks. OK, have you sat down and talked about it? Have you been to see an expert? Do you need to get away, together, for a weekend?

We need to first find the ‘Root Cause’ of the problem, or the fundamental underlying issue, that sprouts all the chaos above ground before we can try and solve it. This is known in the trade as ‘Root Cause Analysis’ (RCA).


When engineers come across a machine that is broken, or one that is just not running quite right, they might ask ‘why’, and then ask ‘why’ four more times again. 

This is a technique in engineering, called the ‘5-Why’ method. Developed by Sakichi Toyoda with the Toyota Motor Corporation, it is a system that aids you to find that fundamental problem. 

————————————————————

There is a dent in the wall – why?

Because the door has been hitting it – why?

Because the stopper has come loose – why?

Because the stopper only has one screw in it – why?

Because the other has broken – why?

Because it was the wrong size screw. ROOT CAUSE

————————————————————-

To fix the problem of the dent in the wall, we need to find the right size screw to fix the stopper in the floor.

As you expand into environments with thousands of components, machines and processes, accurately finding and defining the ‘Root Cause’ of the problem is the key to success.

The better you can make your ‘problem definition’ the more clarity and focus you have to fix it.  

————————————————————–

I’m struggling with money – why?

Because the money runs out before the end of the month – why?

Because I’m spending more than I’m earning – why?

Because I don’t know how much I spend each month – why?

Because I don’t have a budget – why?

Because I never thought it was needed. ROOT CAUSE.

————————————————————-

When completing this exercise its vitally important to stay focussed on the problem at hand and not to deviate off onto problems in other areas. Take these two examples for instance.

————————————————————-

I’m always late for work – why?

I always hit rush hour traffic – why?

There is a junction where all the workers in the neighbourhood must pass and the queues are a nightmare! – why?

Because the road system is not good enough to cope with the traffic levels – why?

The designers of the roads didn’t know what they were doing?? 

————————————————————–

This is not finding the root cause of the problem. The process is an iterative cycle and as we know, anything that rotates tends to move things outwards, due to the centrifugal force. Therefore it is vitally important to keep the focus inwards, on factors you yourself can control. 

—————————————————————

I’m always late for work – why?

I always hit rush hour traffic – why?

Because I start work at 8 and therefore I leave at 7:30, just like everyone else – why?

Because that’s the routine I have had for many years – why?

Because in the past, setting off at 7:30 was fine, until they built that new factory last year, now the traffic has increased – why? (stay inward focussed here!)

Because when the situation changed, I didn’t continually analyse my day, and figure out a new, more efficient process. ROOT CAUSE.

———————————————————-

A word of caution though. If you complete the ‘5 whys’ correctly, it’s going to take you to some places that may really challenge you emotionally. This can be disruptive, but the reward is worth the work. Below are examples I recently completed for my normal day-to-day job situation. I could sit down and blame the company but the root cause of my problem lay directly at my feet. 

————————————————————

I’m unhappy at work – why?

Because I don’t feel motivated to do it anymore- why?

Because I expect more from the company with regards to the effort I’m putting in – why?

Because they don’t pay the employees any bonuses for the additional hard work we complete, leaving us feeling like ‘why should we bother?’  – why?

Because they don’t see the value in treating employees fairly and we are the ones they should be encouraging to be more of a successful company – why?

Because they haven’t been trained on how to run a successful company? NOT A ROOT CAUSE for my problem. 

————————————————————-

As you can see this is not solving the problem of why I am unhappy at work. It’s just moaning about the situation and my focus has been cast external, not internal. The inward ‘5-why’ method for my job situation actually looks like this.

————————————————————–

I’m unhappy at work – why?

Because I don’t feel motivated to do it anymore- why?

Because I expect more from the company with regards to the effort I’m putting in – why?

Because my research on how the company runs, before I took the job wasn’t good enough – why?

Because I never thought I needed to check on a company, the vision and strategy, reward systems and ask current employees what they think – why?

Because I assumed it would all be OK as it has in the past. But my assumption led me to not checking all the relevant facts and information that was important to me first; and I only found out it was like this after I accepted the job.  ROOT CAUSE

————————————————————–

So now I have two options. I stick it out in the company and accept it for what it is. Or I search for a new job and in that process, I complete the proper research before accepting it. It was a tough lesson for me to learn, not least because it brought me face-to-face with my ego. Such reckoning can be really uncomfortable, and that’s ok. If you’re really struggling with a decision though, I want to encourage you to seek professional support. I assure you, there’s no shame in it. 

But what about the company, some might say? Well imagine in an ideal world, everyone completed really deep research on a company before they took the job. Soon, companies that treated employees poorly would be forced to change their ways as no one would work for them…..food for thought, no?!


Using the ‘5-why’ method is a powerful technique  in directing your vision towards the one thing that needs to be fixed, solved or improved.

It can be used for simple obstacles around the house, or for large challenges like your work, home life or financial situation. 

Sometimes they are quick to complete, sometimes they take days. But when you master the 5-Why method, the results can be extremely rewarding.

And don’t worry, I’ll give you tips on how to solve problems as you find them.  So enjoy!

What would you define your major problems are and what do you think the root cause of them is? Why don’t you take some time out this weekend and try a couple of examples?
