about System Dynamics.

System Dynamics is a popular method of complexity reduction.

It was invented back in the 1970s by a team of scientists at Massachusetts Institute of Technology (MIT) in Cambrige, led by Jay Wright Forrester (also popular for inventing an early concept of RAM, today’s computer Random Access Memory, in the Whirlwind project).

Software in System Dynamics (SD) is able to simulate a Balanced Scorecard over time. 

That’s a number of Input Values, Targets and Formulas on a sheet of paper, describing any technical or natural dynamic system (for example, a production circle in a company). Therefore, SD is used for behaviour prediction, amortisation, and all kinds of cost-usage calculations. The prediction aspect comes from calculators like ours, which allow you to see how these values influence each other, and keep changing over time.

You can see a Balanced Scorecard as being just a simple overview of the situation on a sheet of paper. Most collegues from worldwide System Dynamics Society call this kind of sketch a Causal Loop Diagram, and in their language, an Input Value is called an Auxiliary and a Target Value is called a Flow.

As we all know, in nature, Everything Flows, so they gotta point there, but at Dynamic Applications, we prefer understand-ability. So we try to use simple words that are a bit more self-explanatory.

At Dynamic Applications, we are developing a free Business Dynamics Platform for everyone. This means that it’s targeting to be free to use, for all simulation models, and free to try (no limitations) for the premium version, so that’s why we hide Universal Promo Codes on Twitter, world‘s fastest network, and this very Website in all kinds of locations. It’s part of the game, our game of life in being business owners. In contrast to the scientists, who are paid by the state for their experiments and teaching. In a way, that‘s also some kind of balance. 

See our brand-new, free do-it-yourself Tutorial on business model development to find out more about that. 

At Dynamic Applications, do-it-yourself is free. It‘s part of our culture, our small business company ethics here, so it won‘t be changed. As superior culture, confronted with a lot of different people, will define our success over time. Well, superior does not necessarily mean „better“ or altruistic, you know. Think about Amazon, the largest digital shop in the world of today. 

What a long tail of products. What a huge amount of people, hard working conditions, all working for the richest person on earth, Jim Bezos. You can call that success.

At Dynamic Applications, we‘re much about individualism and personal freedom for everyone. On a Balanced Scorecard, we value any person on earth with 1. As many other companies in Business Dynamics, we do workshops with rich people, and with poor people, and everyone will be allowed to speak and be heard. This is because we feel here that an important idea for describing a successful company scenario could as well come from a rather poor, seemingly unimportant person. 

The reason for this is that poor people have a good feeling for need, and in business development, we say that need is a good measure for success where, ever we meet it in high enough numbers.

Let‘s agree upon that success is a common target in business, just the question what is success has various interpretations, or scenario variations, as we call them in System Dynamics expert language. So we calculate all kinds of scenarios means we check all kinds of options, and in allowing you to change any single driving screw of your company scenario over time, we allow you to check a lot of options in short time.

Finally, you can select your Target Value of choice and maximize its outcome. It could be net profit over time, so you can pay your employee‘s salaries.

But it could also be natural growth, it could be contribution, it could be better material, it could be usability, reduction, beauty, customer productivity, website visitors, positive feedback loops, or excellence. 

To achieve excellence, for example, you may choose not to rise your prices, as a general habit. So you don‘t buy better material just to sell your products at a higher price. That’s also possible, but that‘s what we call just a switch of market segment, and your natural trade-off will be less customers. 

To achieve excellence, you buy better material whenever someone comes up with a good idea on how to optimize your production circle. It allows you to produce cheaper, and so you‘ll have additional income over time, as you can sell more products, even higher quality products, at the same price. 

You let your Team test it, and as soon as you have a proof-of-concept, as the first very few customers love it, you can invest your money ahead of time. You keep fine-tuning your process to be able to offer a better product at a lower price. In case you wonder what we mean by better, or how to measure and now you wonder what that really is, check out the Dynamic Idea and Roadmap competition, a pretty fine approach in online democracy

It’s based upon Swarm intelligence, which we have implemented in a small algorithm written in Twitter, a fairly modern programming language, upon a 400 million user database. Be free as a bird. Tweet your thought to me. Make it better, and get the winner, for free. Or just let it be, and use it, as you prefer.

Pay with a Tweet.

So now you know how we do interprete success over time, at Dynamic Applications, but as i said, if you look very closely, there‘s as many interpretations of success or so many important Targets as there are people on earth. Just my 2 ct as a small family business founder, you know, writing an early article.

Content is key.

Understanding each other, in high conflict productivity. Person is equal, argument is key, everyone allowed to contribute an idea here, even from that smallest Island in the large, deep blue sea of The International Network.

As long as convincing in argument, it’s already on the roadmap, and where those are in conflict, we’re voting in online democracy. Our target? – a better world.

Our culture.

Success is much about heading in the right direction over time. read on.
We feel that the general approach of System Dynamics is outstanding, and way too good to be forgotten. When talking about Business Dynamics, this basically means SD for business applications. So we invent all kinds of 21st century micro-business models, and write calculations in Desire, our very own System Dynamics-based formula language.


Here’s why.

mobile_gis_logo_48x48

A Balanced Scorecard is basically a sheet of paper where you put all main topics of interest of your discussion into a circle. It could be a cost, a benefit, a profit, a target, a desire. Then, you interconnect these circles with any number of arrows. So you get a good picture of the situation, and are able to see the interdependencies, even if the system or topic of discussion is complex. You get a pretty good overview pretty fast.

As Wikipedia describes it, Balanced Scorecards are forming the qualitative approach of System Dynamics. It is a Top-Down approach, and qualitative means that there are no numbers on the sheet. 

Add a few numbers, derive some early formula from it, now we call that a quantitative approach. If you ask me, some people have invented all those complicated words just to show how genious they are, so they can sell at higher price.

More thinking gives larger diagrams, more precise, but after a while the overview gets lost. World’s details are endless. So a good Balanced Scorecard is in balance, itself. Not too complex, not too detailed. No arrows for rare cases of interconnection.

However, there is one Key Benefit: Understanding.

Helpful Transparency.

Basic understanding of the interconnections any kind of complex problem, like developing a new product, a service, or a specific, fine-tuned solution in detail. World’s details are endless, so there’s always the problem of missing the big picture. This is the kind of problem that Balanced Scorecards can solve. Understanding of all Interactions. Getting an overview of your current situation.

Oh, by the way. Lots of people in the SD community are talking about causal loop diagrams. It’s basically teh same thing, We just liked the word Balanced Scorecard, as it sounds a little more easy to understand. Expert language, you know. There must be a clue in making things sound more complicated as they are (thanks to Robert Koshinskie from North Carolina for his fine review and contribution to this article at this point). Let’s see this paragraph as a contribution to the (exceptional) expert reader, so we don’t lose or start confusing any of them ahead of time.

The team around Jay W. Forrester were working on something better. They were developing an approach to not only look at the sheet of paper. They began to separate the things on that sheet from each other. Circles with a single or multiple arrows starting from them, but no incoming arrows, were typically describing input parameters. Like steering wheels for everything that follows. Circles with arrows going through them were forming formulas. Like, A+B = C, where A and B are Input Values, C is the Target, the result, and the whole thing is a Formula. Circles where all those arrows were ending in, are forming the main Targets of Interest, then. The things to optimize.

And so, these people were developing a methodology to quantify basically any kind of Balanced Scorecard. Then, they put their methodology, their procedure, their algorithms in software, and developed the first specific programming language suitable to describe complex problems: DYNAMO.

After working a while on DYNAMO, they were the first team in the world to feel the capabilities of the approach. So they decided to work on something great. In a time when about everyone around, every country, every nation in the world were industrializing and re-building the world destroyed by World War II as quickly as possible, these people started to develop World Models. Model I was just a prototype. The results were poor, and about noone took interest in the idea. So they developed World Model II. A much better approach, so good that Forrester himself wrote a first book about it, World Dynamics. Apart from a few researchers though, nobody took notice.


So they developed World Model III.

dynamions_logo_48x48

Landscape, Resources, Food per Capita, per Head. And prediction of developments, as good as possible. And results were showing that the proceedings of mankind were pretty similar to what Algae do with a fresh garden’s pond. They populate it, then they get greedy, others are dying, then Oxygen gets low,  and in the very end, almost all Algae are dying from greed, their cells falling to the bottom, and the garden’s pond is clean again. Only very few Algae remain to re-populate it as soon as resources and food would ever return.

World Model III – a historic simulation of 21st century mankind’s limits to growth.
Available Resources. Reduction of Resources by Mining and Oil Production. Worldwide pollution of air, rivers, garbage hills, and ground water. The results hit them like a thunderstroke. And when nobody took notice in the U.S., Forrester decided to speak to a few people forming a discussion circle, an early “think tank”, in Switzerland.


The Club of Rome.

dynamic_qs_logo_48x48

And when the Club of Rome became aware of the results and had verified them, they wrote their own book about the limits of growth, of world-wide exaggeration. At a time when the first oil crisis was just through, the world was ready for a new message. Bigger, Higher, more Spectacular. Limited.

The Limits to Growth became a world wide bestseller in the last 1970s.

There’s one important thing to know about these kind of predictions, though:
they are made to predict scenarios that are not going to become true! So don’t you fear. This is because the system just shows a

what-would-be-if-we-go-on-like-that calculation.

The simulation gives everyone transparency about the situation and its consequences. Then, as with any complex scenario there’s always a hundred or more Input Parameters influencing the outcome of the simulation. In this case, since the calculation goes over more than 100 years, there’s enough time to solve the problem.

So that’s what we mean by transparency as the central benefit, and not the Target Values, as such. In every System Dynamics calculation, there are various Input Parameters, so in the end, all Targets are adjustable. The outcome, your optimal solution, depends on what you think realistic to achieve, what you are willing to do, and eventually, which of your Targets you are willing to sacrifice, to optimize a more important one.

At Dynamic Applications, we felt it’s a little sad that such a fine approach is nowadays almost forgotten, or never really made it past science. The world around us is changing, and things like the Internet have been invented, that haven’t been thought of in these days. Some people say progress is accelerating, as much as computing power does. People start looking for orientation. For understanding. So wedecided to develop simulation models for problems of public interest, like, for example, a forecast on your own bank account’s development perspectives. A free platform to run them and get to know how to solve any kind of complex problem, whether in School, at University, or in Business. Our Vision.

Our platform, Perfect Desire, can be used for Return-on-Invest (ROI) calculations, prognosis and simulation of system and value developments over time, and amortization calculations. Any operative system that features Input Parameters, Formulas, and Target Values calculated by these formulas is suitable for simulation. This may as well be a production cycle, any interaction of things in nature, business and finance, or a critical situation with limited possibilities, a strategic invest decision with long-year consequences, measured by numbers as good as possible.

Combining all the knowledge understood about single aspects in one simulation.


Example: Photovoltaic System.

img_5150

A good example of System Dynamics is to calculate the amortization calculation of a Photovoltaic System (PV System) over time. Amortization against a projection net price developments of electricity, as described here.

It can’t give a final answer, as we all do not know the net price for electricity in the year 2040, when a today-built PV system will reach its end-of-lifecylcle.

But it allows us to get a pretty good picture of the interactions of all those input parameters, like sunshine, battery, and average household usage profiles.

System Dynamics- an approach for top-down solving of Complex Problems.
In all these situations, we are typically looking for optimal behaviour – formally spoken, a parameterization of adressable input values to get a maximum, minimum, or balanced behaviour of a specific, interesting target value over time.

Sounds complicated? – yes!

That’s why System Dynamics is a Top-Down approach. For any complex problem, we start from a single sheet of paper. The perfect overview. From there, we can always refine one of the circles and think what does that depend upon. So the trade-off is that the simulation model gets more complex. It doesn’t hurt much in the beginning, but in the long run, it’s key to success to concentrate on important influences. The good news? well, we start from the Perfect Overview: No Details! We instantly see where we desparately need more detailed information.

And so we keep heading in the right direction over time.


Squaring the Circle

dynamic_idea_dynamic_qs_logo_96x48

If we can find this parametrization and the relevant formulas of the describing model are correct, process of application can be adjusted accordingly, and the proposed results will occur in due time.

So by applying System Dynamics, we are solving optimization problems. Squaring the Circle, that’s what we do here. A very typically solution. In most cases, the best solution is not either extreme.

It’s the optimally weighted point between them.

And the quantification of Balanced Scorecards will help us to find a measure.

We’re aiming at the best possible measure we can get.

World Model III: expansion of World population in 21st century.
The special thing about a System Dynamics Application is that it allows you to change any single input parameter over time, even in combination, and take a look at results beforehand. To reflect that in nature about every existing thing will change over time, and conclude from that.

In the most easy approach, this can be done from past to present, so the outcome is alredy known – a verification of approach, to make sure the formulas are working. However, the same approach can be used to describe the changes of input parameters (personal and material cost, revenue, sales) anticipated from present to future. The remaining guess, the uncertainity here is that we can’t usually forecast things not yet invented.

As the software always works in the same way, the results will be correct in both cases. So, to predict future changes, it is just necessary to anticipate all influential parameters, correctly. The good thing is that whenever we are planning something, we use to guess upon the future change of driving parameters anyway.

Just most people would combine these in their mind, or search for a compromise in discussion. Theory says that a standard person is able to combine 2-3 different, changing parameters in their mind. A genious like Albert Einstein could have done 4. About noone can combine the results of five or more changing parameters in complex interaction in their mind.

But a Computer can do it.

A System Dynamics software application will allow you to anticipate as many changing parameters as you want, and still be able calculate all formulas, resulting target values, and consequences correctly, restricted only by the accuracy and detailedness of the underlying formula.

A collection of typical basic interactions has been researched to describe common issues.

SD_Management_bscd_en_1024x768
System Archetypes: typical Management situation patterns.
The list of System Archetypes, as found on Wikipedia, describes typical problem patterns:

  • Growth but under-Investment.
  • Shifting the Burden.
  • Tragedy of all Common Goods.
  • Unintended Opposition.
  • Eroding Goals.
  • Escalation.
  • Fixes that Fail.
  • Success to the Successful.
  • The Limits to Growth.
  • Balancing a Process with Delay.

Wikipedia has a pretty nice explanatory diagram for each of these System Archetypes.

At Dynamic Applications, we feel this approach can very well be adapted to a typical company, as it covers all well-known patterns of typical Business Management situations.

To conclude, for a complex model as the one describing a photovoltaic installation, system dynamics is a very suitable approach. It allows for the necessary complexity reduction and calculates the consequences of the various described interactions part-by-part.

To deliver a very good result in the final formula, amortization. Balance. Transparency. Verify your own thoughts. Insert your own estimate on parameter proceedings and see the combined result. Fine-tune as many input parameters as you want.

See the proposed outcome, the consequences, immediately. It allows you to play through all kinds of possibilities. It allows you to verify that you haven’t overlooked an alternative. It allows you to find new alternatives, measure them, validate their consequences, and be ahead of competition anytime.

Green City House - 2002.ppt

We think the general picture here, in Business, in Capitalism and free Entrepreneurship, has pretty much in common with playing the game of Chess.

There’s always these people around who swear on Tactics. Concentrate on the next move. Evaluate your situation, your history. How was the current situation developing? – what did our counterpart do? – and what is the next best move. There are people around who use days, weeks, months, or even years of their life to memorize the best known development openings of their favourite board game. And that’s pretty similar to today’s big data approach in business. Hunt for more data, more understanding of the past. And collect as many of them as possible. It seems intuitively right, as it addresses hunting and collecting in one concept. And the latest hype, BigData Analytics, will even be able to show you statistical interactions within data of any kind, without specific programming of any kind. 75% of your customers older than 45 years will prefer product B instead of A. And then, all of these tactically driven companies start to develop key score criteria, just to be able to raise them from month to month, from year to year. Only a thinker would put that in question.

A System’s Thinker (basically a System Dynamics user, who learned to think over time) would focus on the long-term target instead, on developing either a survival Strategy, or a winning strategy. A System’s Thinker wouldn’t read many books, or take a look at all those BigData Charts. They are useful to deduct a couple of formula from them, as you can derive them from Google or Wikipedia on about every important thing invented so far.

The Strategical Analyst would naturally desire a System Dynamics application, and simulate all possibilities in advance. Move 7, 8, 9 input values, like fine-tuning sliders, right after each other. Preview the consequences. Test everything. Get an overview of possibilities. And then, decide for the best strategy that there is around. Pretty similar to playing chess, or any other board game around, isn’t it?

Strategy against Tactics.
