Do costs of ‘improvement’ really indicate the relevance of an initiative?

Improvement: shoot this nag and replace it with a new horse, or ox or a steam tractor. Instead why not just give it decent food, water & exercise? What is the impact? What is the cost?

A lot of money is spent on ‘change’ and ‘improvement’. Often a major restructure or implementation of IT are at the fore in improvement investments with new facilities or equipment upgrades (both of which are costly) are not far behind on the list.

It is also common for money or time (usually both) to be spent on customer surveys or staff surveys to glean ‘data’ which it is hoped will inform what type of improvement is needed. Is this always necessary? Is the money which is spent on improvement a good indicator of whether that improvement will be worthwhile – is it a decent ‘return on investment’. This is not always clear, since a change may set off a spiral of outcomes (which will generate positive cost savings and new negative cost burdens) but which may or may not be included in the overall analysis of ‘total cost’ (when they should really be included).

Pat Nevin identified how a small (low cost) change to the surface around top flight professional football pitches could improve the quality of football during competitive matches; an analysis achieved just by looking at the ‘system’ of football in modern stadiums. The cost-benefit might be hard to gauge, but at very least, reduced likelihood of player injury (e.g. slipping on the surface and twisting a knee) is likely to be worth hundreds of thousands of pounds.

Are IT system introductions always based on knowing how the system should operate to deliver its correct purpose? Are restructures based on knowing how the system will deliver the team’s correct purpose? Will a new piece of new equipment enable a worker to deliver their correct job purpose? Or will these changes just enable a piece of work (which may in itself not be relevant any more) to be done faster, more cleanly, in a ‘modern’ way, in a more ‘user friendly’ manner, yet have no impact on delivery the things that matter (the purpose of the work)?

Understanding the impact of incremental improvements is important. We need to assess what is happening in work, whether the patterns are consistent and predictable, then make a reasoned change and monitor if the impact is positive, then continue the cycle. This is continuous improvement and is based upon building knowledge. It is less ‘sexy’, has lower profile and takes time, but the outcomes are far superior – a better way.

Good Performers will fail in a bad system

Examples of failing systems are numerous, although often the finger of blame for failure is pointed at the people who are at the sharp end (for example, over-worked social workers spring to mind).

ladder of success people

If we cast our minds back to the pre-2012 Olympic Games security shortfall scandal, the British Army had to bring in thousands of troops at the last minute to work as security staff at the venue entry gates, due to critical shortfalls in numbers of trained security personnel promised by a commercial provider. This shortfall was not caused by a lack of recruitment, but apparently by failures in the system of appointing people into the jobs, plus late scheduling of training and induction to prepare recruits to start on-time in their role. Allegedly, some new recruits were never confirmed dates to get their training, others, despite being recruited months before the Games did not complete their training until just a few days before the Games programme ended (so late were the arrangements that many recruits didn’t bother to attend since the Games had only a couple of days to run,  and some people had already found jobs elswhere). These failures were not “nobody’s problem” – they were the problem of managers in the security company.

In a blame culture managers will identify the problem as being the people at the sharp end (so blame those pesky security recruits for not showing up to training just before the Games ended – what a lack of commitment!). Blame is both a self-fulfilling and a self-deluding philosophy.

There is a neat way to define the power of the system, versus the expectations placed on people, in a quote which I understand is attributed to Geary Rummler:

    “Put a good performer in a bad system
and the system wins every time”

But why blame the manager, then? Well, simply, because their job is to manage the system (and to improve it). In fact, that is pretty much all that their job should involve.

Does ‘Best’ method always mean ‘best’ results? Impacts on Service Exellence

Does one size fit all?
Does one size fit all?

Best practice standards are commonly seen as a sure-fire route to successful improvement. After all – who could question the value of implementing best practice? If you are by now used to my writing style (after 3 years of output) you will have guessed that I am one person who would question the value of ‘best practice’.

Why question it?

Any method has to make sense in the context and purpose of what it is trying to deliver. Best practice in cleaning tables might be vital in preparing an operating theatre but might be excessive, costly and irrelevant when applied to a door making factory. The purpose of the work is important. Best practice in answering a phone call succinctly, clearly and efficiently might be the last thing that a service caller with an unusual problem wishes to hear.

I can remember being told by a customer service clerk, when attempting to return a clothing item in exchange for a refund or credit note, that “the company’s returns policy was recognised as best practice in the sector” – but sorry – no I could not have a refund (they suspected, or should I say assumed, that I had already used the item – which I plainly hadn’t). Their answer was no answer and no help to anyone (I did eventually get my refund).*

In services you need to build in flexibility. This means that you have to think carefully about what your users want and therefore what you must do to meet that need – otherwise a poorly considered method will not deliver what is really needed. Deming always used to ask ‘by what method?’

Over and above this, if you do implement a standard way of working, you tend to build in both rigidity (a lack of flexibility to meet differeing needs) and you push users’ experiences further away from the ideal. Seddon states “Don’t codify method” in services – in other words don’t write it all down and demand that everyone sticks to the written code.  But why  – surely standardisation will ensure quality (especially if the standard is shown to be best)?

Imagine – you call a service centre with a particular query in your mind – the telephone menu asks you to press 1,2 or 3 for different services, then at the next menu another 1,2,3. Even if you get through cleanly to the final stage do you really feel satisfied as a user? And what about the false trails, the accidental hangups or the misdirection to the wrong department? It all gets a bit depressing and, frankly, wasteful.

 Even in Ofsted inspections of schools, the error of inspecting and expecting a best method of teaching is now discouraged since the method is dependent on the learning needs and nuances of the students at the point of the teaching intervention. Yes – it figures.

To paraphrase Mitch Ditkoff, when imitation replaces creativity, something invariably gets lost – and innovation eventually goes down the drain.

*P.S. As I gave my explanation they could see my receipt where the value of other items I had bought (with no refund requested incidentally) far exceeded the value of this item by about a factor of 5! As a clearly ‘valued’ customer (read: insulted) I chose to withdraw my custom from that outlet – for about 15 years – the lifetime of family clothing purchases – not out of spite, I may add – I just lost any sense of preference to buy from that store.

 

Improving service starts with a leap of fact, not faith

  • Leap of FactWhat should we improve and why?
  • What has changed?
  • How do we improve things, where … when?
  • Who should we involve?

If we start to address these questions and filter out assumptions and  preconceptions, we are able to make some sensible decisions about how to make effective changes that will have a positive effect on performance.

The world is not perfect and we are unlikely to always have the time and resources to gather the complete picture of what is happening. Nevertheless it is important that we seek out and analyse relevant data in order to make some reasonably robust assumptions about what we can do.

There are two common failures of action, lets call them type 1 and type 2 (which is what statisticians call them), or perhaps a mistake in identification between ‘common causes’ and ‘special causes’ of variation. Without understanding the difference we risk just ‘tampering’, where we feel like we are doing something useful but actually only making things worse (Deming, 1982).

“Common Causes”

Common cause situations are those where performance goes up and down over time and if analysed properly can be seen to occur over a relatively predictable pattern: if we change nothing, the performance level will most likely continue. The problems arise when  someone thinks they see a real difference between points of data when in fact no such thing exists. This a type 1 error: we observe  a change which is really only a natural effect of background ‘noise’ yet we choose to act on that ‘change’. For example someone in the office achieves a great result whilst others do not achieve the same result. Is the difference because of the person, or something else in the wider context? Perhaps, as is often the case, they just got lucky and happened to be the one that achieved the good result. Next week it might be someone else. The analogy  is a fire alarm going off indicating a fire when in fact there is no fire. It is easy to fall into type 1 errors assuming highs and lows of performance which don’t exist. This is a ‘mistake of commission’  – doing something that should not have been done (Ackoff et al 2006).

“Special Causes”

Some special causes are obvious, for example a major increase or decrease in performance or a freak accident. However, sometimes hidden patterns of performance can indicate a real change which might easily go undetected if we consider each data point as a ‘one off’. This is a bit like a fire breaking out but the fire alarm not ringing. The fundamental problem is that these genuine changes are due to ‘Special Causes’ something real which is impinging on the system. The issue here is that the solution sits outside the system – don’t redesign what you have as it will not replicate the situation – that is just meddling and will make things worse. For example, cycles of deteriorating work output followed by improving work output by one person might indicate an underlying special cause which needs to be addressed (health for example), so meddling with the design of the work in itself would be counterproductive. Furthermore if the manager does not look at performance over time, these cycles might not be detected anyway – on average they might look like a reasonable level of output. Ackoff calls this a mistake of omission – not doing something that should have been done.

Of course to detect differences between special cause and common cause varuiations in performance requires new skills and disciplines of thinking. When you understand the organisation as a system, improving service starts with a leap of fact, not faith.

Lessons from the 2014 football World Cup!

german teamIn a late response to the drama of the football world cup I have a list of lessons learned prompted by HR Grapevine. I have amended their proposed list and have included a couple of items which I have interpreted quite differently, so here is my personal list:

1: Don’t be too reliant on one star player

A number of matches have shown balanced teams succeed ahead of those that relied on one star player. Argentina’s Lionel Messi underperformed  in the final and the German team got the result. Brazil struggled as soon as Neymar was ruled out through injury. Uruguay were at sea without Suarez. Weeks earlier in the tournament England were too reliant on the Rooney factor and appeared simply not to set up to act as a unit.

The system should be greater than the sum of its parts, and no more so than in a team. Algeria, Mexico and Costa Rica performed above and beyond expectations.

The same is true about the capability of any team.

2: Trying hard will only get you so far

I think the England team were well prepared and earnest in their efforts (despite the hype  – both negative and positive – from the tabloids). Best efforts are often a sure fire way to failure (Deming has a lot to say about this). However mediocrity can be turned around – but this needs a transformation in approach.

A huge amount can be achieved by engaged the people who are ‘good enough’ to enable them to perform even better (see point one above).

3: Utilise technology  – if it makes sense to do so

FIFA endorsed the use of goal-line technology to deal with the age-old problem of knowing whether a ball had crossed the line for a goal or not. This is not new technology – similar approaches have been used in cricket since 2001 and tennis since 2006. The issue is will it solve the problem? It has been a great success.

Another nice innovation was the marker foam to set positions of defenders in a ‘wall’ at free kicks. Again this was a repeating problem – could we make the job of the referee easier to implement? Simple and effective and in this instance no digital technology in sight.

The first question with technology and innovation is – will it improve what we want to achieve?

4: You need to align team and individual goals

One of the big stories for England in the run up to the world cup concerned whether Wayne Rooney would finally get a goal after 3 unsuccessful tournaments. A bigger question for England fans should have been ‘who cares?’. Ultimately the world cup is not about individual players achieving anything it is about a team wining the championship. All else is a side story.

The problems occur when one person’s goal overrides the team’s goals. Did Rooney shoot when he could make passes to better placed team members? Did he dive into shots which other players were about to take themselves? Did he neglect his defensive duties on the left against Italy allowing them to win the match? There is evidence that points to all of these things. Did England switch off once Wayne had ‘got his goal’ in the game against Uruguay ? Who knows?

The winning German team successfully rotated a whole range of players to do the job. The Netherlands played a recognised centre-forward as a wing back (Dirk Kuyt) and he studiously grafted into that unfamiliar role with great effectiveness. The Dutch even drafted a substitute goalkeeper just for the penalty shootout.

5: Clarity of purpose, identity, belonging and vision pay off

Germany’s plan to recapture the world cup (which they last achieved in 1990) started back in 2000 after a poor showing in the European championships. The German Football Federation invested heavily in the future with new academies and a manager with a long-term plan.

They developed an identity for German international football and engaged players on the basis of playing to that philosophy.

A footnote to this is that German midfielder Sami Khedira picked up an injury in the warm up a few minutes before the start of the cup final and had to be replaced. Khedira will be devastated to have missed the game, but it was clear in the post match celebrations that he revelled in the team’s success and fully identified with the achievement of the team for the part that he had already played in the tournament up to that point (see point 4 above).

 

An alternative view is offered at HR Grapevine:

Finding space to relax, flow and perform

zen bike flow ellipseMany of us have had an experience of ‘getting in the zone’ with work – in the office, in the garden, in physical pursuits, in sport, in artistic or musical endeavor. Things just hit the spot and we are performing at our peak…satisfaction is part of doing it.

As Brian Clough, the outspoken, but assuredly talented European Cup Winning football manager once said “Remember this…you can’t do anything to the best of your ability unless you relax. Nobody can. Nobody can…you’ve got to relax, then it ‘oozes out of you’  – IF you’ve got anything in you.

Csikszentmihalyi emphasises this idea in his book ‘Flow’, where he describes the phenomena as:

  • intense and focused concentration on the present moment
  • merging of action and awareness
  • a loss of reflective self-consciousness
  • a sense of personal control over the situation or activity
  • a distortion of your awareness of time, one’s subjective experience of time is altered
  • experience of the activity as intrinsically rewarding

Can we ever hope to get close to this in the world of work? On the basis of Csikszentmihalyi’s ideas, three things could be considered in the way we design work:

  1. Goals are clear (we know what and why we need to get on with the work)
  2. Feedback is immediate (if we are, or are not, doing things correctly – we see it ourselves)
  3. There is a balance between opportunity and capacity (we can do it and we have permission)

Of course we also have to be bothered about the work. We have to care –  the goals of the work should relate to our own purpose. This idea, in relation to Quality, is explored in Robert Pirsig’s famous philosophical fiction book ‘Zen and the Art of Motorcycle Maintenance’ (Pirsig highlights this book “…should in no way be associated with that great body of factual information relating to orthodox Zen Buddhist practice. It’s not very factual on motorcycles, either.”).

People should have a sense of purpose, should care about their work, should have their own goals, sources of feedback and the capactity and opportunity to perform. Maybe managers should reflect on this the next time that they: don’t allow people to make decisions; give jobs to people who lack capability; offer their own ‘feedback’ in the absent of decent measures which staff could use for themselves. There are lessons for us all…

Incidentally, Zen and the Art…’ was rejected by 121 publishers before finally being accepted (a world record for a bestseller). It has since sold more than 5 million copies. There is probably something in that for another blog…

Should we say it again? People are not the problem.

chimp at wheelDeming famously stated “I should estimate that in my experience most troubles and most possibilities for improvement add up to the proportions something like this: 94% belongs to the system (responsibility of management), 6% special.“. In other words people-related ‘fault’ will be part of the minority 6%.

This statement tends to set people into a degree of  hand-wringing ifs and buts: ‘surely he meant this only in a manufacturing system’, ‘ what about the difficult people?’, ‘ what if they are incompetent?’, ‘I am sure folks are the problem 40% of the time’ etc…

Chip and Dan Heath share a trivial, but insightful example in their book ‘Switch’. They discuss a situation (part of a research exercise) where moviegoers eat significantly more popcorn if they are given large buckets, than if they are given small buckets. To the outsider it looks like the people are ‘Popcorn Gorging Gluttons’ and we may feel that we should judge them as so. In reality, their behaviour (eating excessive amounts of popcorn) is driven by the system – the size  of bucket they have been given. Change the bucket for a small one and their behaviour changes – they seem like moderate consumers. The system is the problem (large buckets), not the people.

“But aha – surely it’s their fault that they choose to scoff down the popcorn!”. True, we are sentient beings and can make choices (for example, I would hope that people who are aware of supermarket sales floor design are less likely to buy excessive amounts of fresh baked goods, fresh fruit and ‘buy-one-get-one-free’ items). I am not suggesting that we should excuse everyone of their behaviour 95% of the time. There are other things to consider – for example do we run on autopilot too often (Do we let the chimp drive the car? More for a later blog I think…)?

However as a start we need to be honest enough to examine our own assumptions as placed upon others and how we judge their behaviour. As the Heath brothers suggest, to do this we need to encounter a deep-rooted phenomenon identified in psychology.

 Kendra Cherry explains -“When it comes to other people, we tend to attribute causes to internal factors such as personality characteristics and ignore or minimize external variables. This phenomenon tends to be very widespread, particularly among individualistic cultures.

In Psychology this is known as the fundamental attribution error – we automatically assume that the person’s internal characteristics are the cause of behaviour even when other possible influencing factors are present in the situation.

So let’s pull away from assumption and open our minds to what is really happening with people.

It’s the environment isn’t it?

There has a been a recent flurry of interest in workspace design (http://www.bbc.co.uk/news/magazine-25355618). Google, Apple and Facebook are often cited for their creative office spaces, designed to enable or even enhance the creative thinking of their staff.office design

However it is not clear if a creative office space stimulates creative thinking, or whether it is the elimination of bad office design that appears to free up the minds of workers (i.e. workers may have been creative already, but just get it sucked out of them by a poor environment). After all did the innovative and creative workers of the past have wacky working environments (maybe they were  not really as creative!)?

It could be that the managers of these organisations might just be fiddling with ‘hygiene factors’, the things that Herzberg identified in the 1960s as having no positive impact on motivation, but are merely the basics that need to be sorted out (along with pay, management style, working relationships etc). Over the long term there is a risk, unless the managers at these organisations are doing something else, that their workforce may not be motivated to make a real difference to the performance of the business – will they still have leading products and services of the future or will better alternatives emerge from their competitors?

Over the past few decades it has become clear that whilst many ‘enlightened’ managers have dutifully followed the good manager mantras: developed themselves as leaders, worked on motivating staff, built trust and rapport, coached and developed, and engaged in team-building, the things that really matter is a common sense of purpose,  how work is designed and what power people have over decisions and quality of the work that they do. This sounds fine in theory, perhaps, but in reality job design often sits in the lap of central departments (like HR), rather than the worker or the team, so the power even to design jobs is not at the point of knowledge – the people doing the work. The result is that managers can only be left to fiddle around the edges with team-building and cheer-leading. Or perhaps some just repaint the office.

An effective manager will learn how to understand and design work and how to engage people to ensure improved performance. An effective team will seek a clear purpose, investigate how their performance affects users, will challenge thinking, ask questions and engage in  improvement.

What makes us ‘professional’ university administrators?

Professionalism is something you see, hear and experience and is comprised of a set of behaviours.  A professional always aims to give the best they can.

As university administrators, we seek to maintain high professional standards.  We could do an “acceptable” job – but we always try to do an “exceptional” job.

But have we ever stopped to consider what makes us professional?  We asked this question to our colleagues in the Professional Administration Centre in the School of Engineering and Digital Arts and came up with several ideas as follows:  Our approach to service – we put our customers and users first (students & academic colleagues).  We are qualified (graduates or with graduate level professional qualifications).  We have numerous competences and skills and are good at what we do.  We strive for greater performance and for continued professional development and we belong to the professional organisation for University administrators (AUA), who provide us with a toolkit and resources to help improve our professional behaviours and deal with the ever changing complexities of Higher Education.

Students use our services, as administration staff,  as their first port of call. The blurring of lines between professional services staff and teaching staff has meant that in recent years, we have taken on more of the traditional duties of the “academic” and there is a constant need for us to provide a greater level of service outside of traditional teaching and research functions.

Twenty first  century university  administration staff sees administrators adding enormous value to, and impact on, the whole student experience, to the extent that front-line teaching, research,  enterprise and all external and commercial activities are greatly enhanced by the kind of day to day roles that we  provide.  We respond to customers’ needs, pursue complex tasks, deliver innovative solutions, drive the student experience, facilitate learning and development, effect outcomes and respond to change.  As professional university administrators, we provide high quality professional services, we have developed an appreciation of academic culture, are sensitive to the needs of a variety of diverse clients, accept responsibility for our actions and share expertise and good practice.  As such, the crucial role we play is integral to the strategic success of the University of Kent

In the light of the University of Kent’s 50th anniversary, it seems like a timely opportunity to showcase how the administrative function has changed in the last 50 years.  We should be celebrating the professional value we bring to the organisation and indeed, our own professional identity.

Absorb variety and increase excellence

Trying to address the demands of variety is a perennial problem. Customers wanting different features in a product, a different colour, a different size, a specific delivery slot, a student wanting specific feedback on their essay. In times gone by, the craftsman would make things according to what the customer wanted. Take the blacksmith – he would manufacture a horseshoe (or shoes) specific to the horse that was presented to him by his customer. A unique shoe every time, or at least finished from a blank to fit the foot perfectly. If you didn’t make your own clothes, you would buy from someone who did, and the clothes were produced in the same way – fitted and finished in the cloth of your choice.

Increasing numbers of customers (and therefore volumes of production) gradually made the provision this type of offer through ‘cottage industries’ more difficult. Bakers had almost always produced batches of loaves for a range of customers, for example, whilst drapers, haberdashers, corwainers and milliners largely did the same. By the 1900s Henry Ford had taken things to the extreme when he produced the Model T Ford, stating memorably in 1909 that any customer “can have a car painted any colour that he wants so long as it is black”.

model T
Also in white…

Today we are used to buying off-the-shelf or off-the-peg products and services, from fruit to footwear, from breakfasts to banking. Standard products are so familiar that off-the-shelf is seen as inferior and run-of-the-mill. Of course commercially this has become a NEW point of competition and differentiation. Marketeers have identified ways in which we can customise the products to suit our needs. Why?

The reason for wanting to differentiate is, at a superficial level, because we like it. The reason we like it, however, is because we have different needs and at a fundamental level we want a product or service that meets our needs.

So what is there to do about this if we are offering services, whether financial, commercial, educational or other?

Somehow we have to design our services to allow people to request variety, so that a variety of requests from many different customers can be absorbed by the system. Does this sound like some kind of menu system (akin to the dreaded telephone services; press 1 for …). No! Because if we do that we are just providing off-the-shelf all over again: simply reproducing options based on what we already produce in the workshop (or back-office), we build up a set of stock answers that potentially meet no-one’s needs.

Instead we have to do quite the opposite. We need to design processes to be flexible to meet the needs of users/customers at the point of demand. If we do that then our services will respond to them at the point of need and will deliver against their requirements. Services will then be perceived as excellent by the individuals who matter – the people that use them!
