Convincing Executives to go Lean

I was recently asked how to convince senior executives to go lean. The best way to answer this question is to summarise two contrasting real stories — one that got it and one that still does not — at different ends of the same sector.

The successful case began with a question from a senior Director — “How could these lean Toyota ideas help my business?” “Let’s take a walk and see” was my answer. As we walked it because clear there was waste everywhere. This very quickly led to a meeting with the CEO who was intrigued and gave us the go ahead to begin some experiments to demonstrate the potential scale of the improvements that might be achieved. But I insisted that we begin by taking a team of top managers from this company and a few of their suppliers to walk the end-to-end process back from the customer. This proved to be a game changing experience — they were shocked at what they now learnt to see!

So we were quickly given several places to carry out experiments and these quickly showed huge amounts of wasted time and effort could be saved. At the time no one had tried to do these things in this industry, even though I had the Toyota example as my reference model. Meanwhile teams from both companies began meeting to reap the low hanging fruit they could now see. And their internal team worked with other consultants to calculate the financial implications of the process savings we were demonstrating from each of our experiments. This was essential to get Board approval to go further and do the next set of experiments. In each case once this had happened their team worked out the operational detail before rolling out the next piece of the system as the new standard across the business.

Gradually as the different pieces came together more savings were uncovered. The fastest things to change were the physical operations and it took a few years before the systems could be changed to support the logic of continuous flow. But the CEO was quick to spot new capabilities he could build on to introduce new business models that were previously too expensive to do. The rest is history — they moved from an also ran in the UK to number three in the world in a decade and their competitors are still struggling to catch up with them! The Board never lost sight of the core insight that removing any interruptions to the flow of products through their system would be good for them and their customers and they never used lean language to describe what they were doing, even though their Chairman is a great admirer of Toyota!

The other case also started with the same question — but from the head of improvement. Several meetings in hotels eventually led to a visit to HQ to meet the new CEO. This company was making huge profits so I did not get a clear answer to my question “Why do you want to do Lean?” This was followed by days of meetings with armies of very bright staff in the improvement function at HQ and a few awareness training sessions. Which were followed by more visits and more meetings to refine our PowerPoint proposals and to develop their Training Manual and the Plan for rolling this out across several hundred plants across the world. These visits continued for several months, and frustration began to set in.

Meanwhile we persuaded them to allow us to begin some experiments in chosen plants to build some demonstration sites and create a network of people with hands-on experience. Because this company had a long history of rolling out new initiatives from HQ local plants were very wary of this new programme as they saw it and jealously guarded their independence and as a result these experiments quickly ran into political problems. Our approach was seen as rocking too many boats and they began to look for more traditional consultants who would stick to training and improvement workshops. This came to a head when we were only allowed to do our workshops in hotels and not on the shop floor and when their central improvement team asked for our proposals and then blocked us sending them to the CEO!

We probably learnt more from this “failure” than from the earlier success. In retrospect we failed to get them to define the business problem the CEO was trying to solve with lean. We never managed to persuade his senior team to take a walk through the process with us. We were told this could only be done with an army of minders and a big security presence. We never convinced them that this was not about rolling out new tools across their plants but about getting to action quickly to design a set of carefully controlled experiments to create hands-on knowledge and examples.

But the biggest obstacle turned out to the very bright staff in the improvement function at HQ who wanted to control the roll out of the programme based on their theoretical understanding rather than hands-on operational experience with lean. I have since seen very similar situations in several big multinationals, where we were in danger of getting sucked into a never ending cycle of meetings to discuss ever more elaborate PowerPoint presentations that never result in any action!

But I do not despair — we planted the seeds of lean. I know that several of their competitors have got it and are making steady progress and achieving dramatic results. As these translate into growing market share and volumes this company will be back in a couple of years asking why all the money they spent on more traditional consultants did not yield the same kinds of gains. Resisting the temptation to say “we told you so”, we can begin again with a bottom up programme of controlled experiments, tightly focused on closing the vital few gaps that will make the biggest difference to the business. Over time we will link them together and build the community of experienced lean line and plant managers who can make it happen day in day out. The focus and the will to work across functions to make this happen can only come from the top. I have always said that I only need one company in each industry to really get what lean is all about — and in time the rest will be forced to follow!

The Waste of Management

Just imagine that instead of pursuing several hundred projects your organisation was able to focus everyone’s’ efforts on the vital three to five strategic objectives that would make the biggest difference to its performance and that keep the top team awake at night. Imagine that the top team had identified the size of the performance gaps that need to be closed to meet these objectives.

Imagine that they had all walked the processes or value streams responsible for these gaps to begin to see the root causes and the opportunities for eliminating wasted time and effort, particularly between departments. Imagine that someone was given the responsibility for improving these value streams by gaining agreement based on the facts on what needs to be done. Imagine that each department had come up with what it could contribute and had discussed the resources required to do so. Imagine all the potential conflicts between the departmental objectives and the needs of the value stream had been addressed in an open manner.

Imagine that everyone used the same evidence based, scientific method to create their own A3 plans and an overall A3 plan of action to improve each value stream to close each performance gap. Imagine that they had agreed to replace the several hundred metrics for judging their performance by a vital few. Imagine that these plans were built around a visual wall that was updated in real time.

Imagine daily maybe half-hour long stand-up review meetings at this visual wall to discuss what to do immediately about deviations from these plans rather than tedious monthly review meetings trying to justify why things had not gone according to plan way after the fact.

It is not hard to imagine the acceleration in performance that would result from this much more effective use of management time. I call it “Results Driven Lean”, where action is only taken to resolve clearly defined problems with an evidence based plan to achieve measurable results in value stream performance that are translated into money — cash freed up, falling unit costs, capital expenditure saved and growing sales and margins from fulfilled customers etc.

My hunch is that this visual approach also defines an effective operational framework for cross functional cooperation. The focus on improving the end-to-end processes of value creation can also help to restore the balance with over-powerful functions and departments pursuing their own objectives, which have become a major obstacle to change.

It is also significant that the top team sets the example for the rest of the organisation by doing it themselves on their own work, which gives enormous credibility when they ask everyone else to follow their example. It also means they are in a position to mentor the next level down in the disciplines of evidence based planning and problem solving by asking questions to teach them how to think rather than telling them exactly what to do.

This is no dream — but what is emerging as we explore the potential for lean evidence based management to transform the lives of managers in the same way as lean has transformed work on the shop floor. Indeed it is the necessary corollary of that work if lean results are to be sustained.

Looking back many of these things made the initial lean supply chain work at Tesco so successful more than a decade ago. As we discovered more recently it is exactly what NHS hospitals need now to replace their totally inadequate public sector administration systems. And it is the focus of the pioneering work by Takashi Tanaka, who spoke at our Lean Transformation Summit two years ago, at Boeing and several other organisations.

All this leads me to conclude that the most damaging form of waste is not on the shop floor but the waste of management. Visiting many head offices I am struck by the armies of bright young people rushing from meeting to meeting making PowerPoint presentations to each other and by the time and effort senior managers spend in long meetings reviewing their plans and gameing many not very clearly defined objectives. These bright young things also effectively insulate top management from what is really going on in the organisation.

The fraction of management time that actually results in improvements in the way these organisations create value must be pretty small, dwarfed by the amount of time they spend fighting fires. But, as on the shop floor, they are all good well intentioned people trapped in broken and dysfunctional management processes that drive them to do the wrong things.

For me the insights that we need for taking lean into the executive office do not come from boot camps on lean tools for executives or even from the lean practice in production and operations. The more promising route is building on the experience with lean in managing projects in the engineering office, which is much closer to the day-to-day experience of leaders managing all kinds of projects in the executive office.

I see lean thinking and the Toyota example as the next step in our long journey to use the scientific method to improve social organisations. Alfred Sloan used scientific methods to create strong functions for command and control. In my view lean provides the scientific basis for working together more effectively, whether on the shop floor, in the engineering department or in the executive office.

This is the frontier for those interested in reaping the full potential of lean thinking and the Toyota example. We are now at a point where we can review the early experiments to test the hypotheses that emerged from diagnosing the root causes of the waste of management. Which is why this will be a core theme at our next Lean Summit on 2-3 November in Kenilworth, UK. We have a long tradition of only organising Lean Summits when we have something new to share. Now is the time to address the waste of management.
