Karol Adamiecki: Management Harmony

We tend to think of leading management theorists as coming from the United States. This seems especially so of Scientific Management. But when the privilege of naming things for the world’s largest audience goes to those who write in English, history creates a bias. And because that audience largely reads only one language, that bias gets amplified.

One of many losers from the Anglo-centric nature of management and business thinking was Karol Adamiecki. He was a Polish engineer, turned economist and management thinker, who can claim to have invented the Gantt Chart before Henry Gantt, PERT before the US Navy, the Theory of Constraints before Eliyahu Goldratt, and much of Scientific Management before FW Taylor.

Karol Adamiecki 1866-1933

Short Biography

Karol Adamiecki was born in southern Poland, in 1866. He studied engineering at the Institute of Technology in St Petersburg, graduating in 1891. He then returned to his home town, where he took charge of a steel mill. He stayed for nearly 30 years, during which time, he formed his ideas about management.

In 1919, he left the mill, and became a lecturer at the Warsaw Polytechnic, becoming a professor in 1922. There, he further codified and published his ideas. In 1925, he founded the Institute of Scientific Management in Warsaw, becoming its Director and remaining until his death in 1933.

Adamiecki’s  Law of Harmony in Management

While running the steel rolling mill, Karol Adamiecki developed sophisticated thinking around management that was, from our perspective, ahead of its time. The three principal components were:

  1. Harmony of Choice
    Management should select and supply production tools that are mutually compatible. He went on to argue that this should be especially so in terms of their output production speed. This anticipated the Theory of Constraints, and the ideas of Eliyahu Goldratt by 75 years or more.
  2. Harmony of Doing
    Sequencing and scheduling of activities need to be fully co-ordinated to optimise production efficiency. Here, he not only developed a tool that looks very similar to the Gantt Chart, well before Gantt published. His approach also anticipated the US Navy’s Program Evaluation and Review Technique (PERT) and du Pont’s Critical Path Method (CPM) by over 50 years.
  3. Harmony of Spirit
    I imagine the Pharaohs’ overseers were constantly emphasising the importance of creating a good team. But this is another theme that feels very modern – perhaps even more so than the other two. Let’s not forget that Taylor’s view of Scientific Management was mechanistic and process-oriented. It took Mayo to bring humanism to the fore, and ideas of team working in management only started to dominate from the 1970s.

Adamiecki started to publish in 1898, several years before Taylor did so.

Harmony of Doing:
The Harmonograph or Harmonogram (or Harmonograf)

In 1896, Adamiecki solved the problem of sequencing and scheduling in production and published, in1903, his solution. He called it a Harmonograf. And it looks very much like what we now call a Gantt Chart. However, Henry Gantt did not publish until 1910. There is no evidence to suggest Gantt copied Adamiecki’s idea.

In constructing the Harmonograf, however, Adamiecki describes a process that is pretty similar to the PERT and CPM methods. He certainly is able to include critical path and float. These are two concepts Gantt did not consider at all.

As Adamiecki described his methods, he was able to optimise production schedules by sliding paper tabs and arranging paper strips. In a very real sense, he developed an analog scheduling computer.

Assessment

Without a doubt, Adamiecki’s thinking was of its time, but way ahead of its rediscovery. He possibly failed to realise just how valuable it was. But more likely, he simply suffered from an Anglophone bias in scholarship and manufacturing. Publishing in Polish simply did not get him recognition far beyond the borders of his home country. Even now, it is only in the Karol Adamiecki University of Economics in Katowice, that his name is celebrated.

And I have to ask, could this happen again? Yes. I think it can, will and probably is happening now. Last week, we met Vlatka Hlupic. Arguably, her work is known despite her Croatian origin, because she lives and works in London. With the US and the UK increasingly looking to close their borders for differing but related reasons, the next Karol Adamiecki’s work could well lay undiscovered for just as long as that of the first.

Henry Gantt: The Gantt Chart

Who invented the Gantt Chart? This is a question I ask in many of my project management seminars, and the commonest answer/guess is ‘Mr Gantt’. Why does nobody suggest Mrs Gantt? In fact, neither answer is properly correct. But nonetheless, the Gantt Chart is Henry Gantt’s enduring legacy. But there was more to him as a manager and thinker than that.

Henry Gantt

Short Biography

Henry Laurence Gantt was born in the southern US state of Maryland in 1861; the year the Civil War started. As one of my reference books puts it, the war ‘brought about changes to the family fortunes’. His parents were slave owners.

Gantt graduated from Johns Hopkins University in 1880 and, after a few years of teaching, qualified as a Mechanical Engineer in 1984, with a master’s degree from the Stevens Institute of Technology in New Jersey.

After three years working as a draughtsman in Baltimore, he joined the Midvale Steel Works in 1887. This is where FW Taylor was Chief Engineer, and Taylor was to become a mentor and important intellectual influence on Gantt. The two worked well together, and Gantt followed Taylor first to Simmonds Rolling Company and then to Bethlehem Steel.

They went their separate ways in 1900, and in 1901, Taylor endorsed Gantt as the best person to have as a consultant for implementing their shared principles of scientific management. This led to a successful career for Gantt; working with many large corporations. From this point on, though, Gantt was clearly thinking for himself and diverging from some of Taylor’s more extreme ‘scientific principles’.

It was in 1917 that Gantt ‘invented’ the now famous Gantt Chart, as a way to speed the construction of naval vessels during World War 1.

Gantt wrote two books – both out of print – and there is also a set of lecture notes available. Beware print-on-demand reproductions – some get poor reviews. His 1911 book, ‘Work, Wages and Profits’, focused on incentivising workers and marked a shift from Taylor’s penal approach to piece rates. In 1919 – the year of his death – he published ‘Organising for Work’. This marked an early contribution to the field we would now refer to a Corporate and Social Responsibility (CSR).

Gantt’s Ideas

We can summarise Gantt’s management thinking under three headings: incentivisation, task management, and corporate responsibility.

Workers’ Incentives

Taylor’s approach to incentivising workers was the piece rate system – getting paid only for the work you do. Gantt moved away from this idea, noting that motivation works best when you reward good work, rather than punishing poor work. So Gantt’s approach was to offer a base wage, with bonuses to workers who performed beyond a certain level. This meant that workers in the learning stages of their roles could earn a decent wage and led to a doubling of production levels.

He went on to provide additional incentives, most notably to foremen. This would recognise the collective efficiency of a work team and provided encouragement for on-the-job training. Gantt had clearly departed a long way from Taylor’s thinking, in the direction of humanistic management, when he wrote in ‘Work, Wages and Profits’:

‘the general policy of the past has been to drive; but the era of force must give way to that of knowledge, and the policy of the future will be to teach and lead, to the advantage of all concerned.’

Gantt was a close contemporary of Mary Parker Follett, with whose thinking this aligns, but I can find no reference suggesting that they knew one another. He was, however, a good friend of Frank and Lillian Gilbreth.

Corporate Responsibility

In ‘Organising for Work’, Gantt set out an agenda for corporate responsibility to society. He argued that the cold ‘buy low: sell high’ approach to business would not meet the challenges of business leadership in the twentieth century. He placed far more emphasis on the role of executives in motivation and efficiency that did Taylor – who saw workers largely as automata.

As he distanced himself from Taylor, he held that businesses have a duty to serve their communities, using the phrase ‘social responsibility’.

Task Management

There is no doubt, however, that Gantt is best remembered (only remembered?) for the Gantt Chart. This is a representation of tasks as bars on a chart that plots a list of tasks down the left hand side and sets a time line from left to right. Each task is shown as a bar. The length of the bar represents the duration of the task, and the placing represents its scheduling. Shading of the bar can represent levels of completion.

This was one of many different charts that Gantt developed, to help make work easier to plan and manage. This was him at his most ‘scientific’.  In his early career, he said that scientific analysis is the only route to industrial effectiveness.

So, did Henry Gantt invent the Gantt Chart?

We will never know if he was aware or not (I suspect not) but the same chart had indeed been ‘invented’ in 1896 by Karol Adamiecki. Adamiecki was a Polish economist and engineer, whose misfortune, if you like, was to publish in Polish and Russian. So, his writings received little attention outside of those countries and we now have the Gantt Chart, rather than the Harmonograph (Adamiecki’s favoured name) or the Adamiecki Chart. It is not clear to me when Adamiecki’s work was available – references I can find suggest he only published in 1931.

Who cares?

Apart from pride of authorship (among two long dead men) or nationalistic pride (between Poland and the US), there is little value in worrying who invented it. I’d be prepared to bet that if we had marks in the sand preserved from the ancient builders of Egypt, Sumer, Meso-America, Cambodia… somewhere we’d find a bar chart scratched out hundreds or thousands of years ago. What matters is the phenomenally wide usage this chart has.

The Gantt Chart is seen as a cornerstone of modern project management, yet it is hard to imagine the impact it had in the 1920s and 1930s, on US industry and Soviet Union central planning. And it has barely changed in the last 100 years. The only real difference is the technology we use to produce the charts and the consequent ease we have in using them to drive calculations.

For this, Henry Gantt does deserve to be remembered. So to, though, does Karel Adamiecki.

This is part of an extended management course. You can dip into it, or follow the course from the start. If you do that, you may want a course notebook, for the exercises and any notes you want to make.


We are working through a series of blogs, looking at some of the essential models that a project manager will need. We will cover:

The Gantt Chart is like a non-identical twin of the Network Chart which we saw last week. It contains all of the same information, but displays it in a different way.

The Gantt Chart is named after Henry Gantt, who did not invent it. As far as I can find (Wikipedia seems clear on this), it was invented some twenty years before Gantt re-invented it by Polish engineer and economist, Karol Adamiecki. Writing in Polish, of course, and calling it a harmonogram , would never endear it to Anglophone engineers and managers, who, if they had heard of it, would probably have thought Harmonogram too effete and musical-sounding a term. Gantt Chart has an air of brutality to its sound and Gantt was a thoroughgoing American.

Building a Gantt Chart

Anyway, let’s convert last week’s network chart into a Gantt Chart.

First, we draw two axes:

  • on one, put a time scale
  • on the other, list all of the tasks

Now, starting with the first task, represent each one by a bar. Make the length of the bar represent the duration of the task, and place it to represent its scheduling, as driven by the sequencing and dependencies of your network chart: voila!

First, here is our Network Chart

Critical Path on a Network Diagram

Now, let’s translate this into Gantt Chart format…

And it really is as simple as that… until your project gets large and complex.
