Five business leaders you should know

Fredrick Herzberg, Steven Covey, Malcolm Gladwell, Napoleon Hill and Charles Handy.

It is difficult to narrow the choice down to just 5 individuals, but I have chosen Fredrick Herzberg, Steven Covey, Malcolm Gladwell, Napoleon Hill and Charles Handy as the most significant mainly because of the influence they have had on others and because of their timeless relevance.

Herzberg I believe has had the most significant impact on organisations’ approach to motivating their staff and indeed his concepts are as relevant now as they were over 50 years ago. Nowadays we hear a lot about employee engagement and this is pure application of Herzberg’s principles and a recognition that those who feel more part of an enterprise and who have more control over their work are likely to perform better and make a bigger contribution.

Like Herzberg, Napoleon Hill is another business thinker who continues to have a great relevance to contemporary business life and it is easy to spot the influence he has had on others such as Covey  and Bandler and Grinder’s work on NLP.  The psychology of intention and outcome is fascinating and many successful entrepreneurs and business leaders have recognised their achievements have resulted through applying the right mixture of desire, hard work, visioning and tenacity. His principles are applicable to people at all levels and not just the aspiring Richard Branson’s of the world. Fundamentally they can help anyone to fulfil their potential if they know what drives them and what they want in life and if they are prepared to work hard for it.

As a journalist, Malcolm Gladwell’s is an observer rather than a theoretician but nonetheless, many of his observations especially in his books ‘Blink’ and ‘Tipping Point’ are having a significant influence on business thinking in the C21st. Tipping point provides a robust and practical guide to building brands and creating recognition in a world where there is exponential growth in the competition for attention. Blink highlights the importance of authenticity of leaders in business and the need for behaviour to be linked to beliefs and values.

Stephen Covey’s work ‘Seven Habits of Highly Effective people’ has created a universal framework for much of today’s senior management and leadership development. Although criticised by some as pure common sense, Covey’s work has provided millions of people with a roadmap which reminds us that excellence and success is not an act but a habit.

Charles Handy has been an important figure in how we view work and our relationship with employers and his publication the ‘Future of Work’ was prophetic. Employment no longer means joining a company for life and the relationship between employer and employee has become economic rather than paternalistic. People now need to manage their own careers and there are no jobs for life. Some feel this is a step backwards but Handy’s concept of Portfolio Careers argues that this creates opportunity for people to take more control of their destiny and fulfil more rewarding careers whilst organisations benefit through having a more flexible workforce which can adapt quicker to change.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
