This is indeed the basics for any succesful Kanban. But why are these two principles the driving force behind Kanban? And how can we teach people these basics in a way that they understand the principles, not only know them by heart?

A two hour game

That is what the Kanban Game accomplishes.In a relatively simple game that takes two hours, participants are stimulated to discuss and understand the underpinnings of Kanban, helping them to become more agile and ultimately more succesful in their business.

The game takes place in five rounds, each focusing on a specific topic:

Keeping the team scores during the kanban game

• Round 1: solving bottlenecks to obtain smooth flow. Work-in-progress limits to help solve bottlenecks.
• Round 2: market variability and agility and the value of stock.
• Round 3: the effect of training: deeper expertise for optimal flow. Broader expertise to limit dependency on disturbances.
• Round 4: process disturbances and how to obtain smooth flow even in unstable environments
• Round 5: kanban, the big picture. How to transfer what we have learned to the real world.

Apart from these five specific topics, following topics will be brought up during the discussions more than once:

• Visualising workflow: why it is important and why it is equally important to keep the visualisation in synch with reality
• Importance of communication and island work versus team work
• Expertise in the head and hands of a limited number of people
• FTE: are people just “resources”? is “adding people” a way to achieve higher production?

Besides that, participants will gain an in-depth knowledge about origami frogs

Free download

The Frog Factory – a Kanban game can be downloaded and used for free. However,

• when you want to share the game with others, please only link to this website. Regularly, new versions will be published so don’t copy the files.
• When you use the game, please give me feedback (agile is all about quick feedback, remember?) so that I can improve the game. Also, ideas for extensions and the like are welcome. Do use the comment button below this page.
• The software and material is provided as is, without any warranty. Use it at your own risk. For example, if playing this game changes your beliefs about how to run complex business processes, don’t blame me.
• Also, honor my copyright. Constructing and improving this game has been lots of work and I provide it for free, so please at least refer to this website when using the game. Posts about the game on other websites are encouraged!

Practicalities

• the game can be played by 6 to 20 people, divided in two equal teams. If the number of participants is odd, a correction applies (automatically calculated by the spreadsheet) apart from the teams, there is one instructor and if possible, an assistant.
• you need a suitable room with a whiteboard, if possible two computers and a beamer, per participant about 12 square origami papers in three colors and four bins per team (any recipient is okay as long as you can put some paper frogs in it)
• room setup: project the spreadsheet with the results and use the other computer for the counter. Put it in the middle so that teams can see the progress of the rounds. There is also a sound signal so constant visual contact with the timer is not needed.

• If your sample size is too big, the research cost may be too high for the value of the results one reaches.
• If your sample size is too small, you won’t even be able to reach valid conclusions

Either way, you loose money and effort. Having a sensible sample size is of crucial importance in most research and surveys.

Until now, calculations of sample sizes were a matter of “sound sense”, or dubious formulas not well understood by researchers. Though the literature is relatively old and specialised software packages allow to perform sample sizes calculations quite well, it appears that most researchers still don’t use this material. Either because they are unaware of it, or because they don’t understand it and don’t want to invest a lot of time in this apparently simple subject. 

Sample Size Calculator - type of analysis

Sample size calculator is meant to help:

• It offers quick, but sound estimates for sample sizes in a variety of situations
• It works like a wizard, offering the researcher only options he should care about.
• It allows to choose corrections for different situations
• It has an easy and flexible reporting functionality
• It comes with an understandable content-rich help file (the text you are reading right now).

Sample Size Calculation

Apart from corrections, there are three main factors that influence sample size:

• Variability: the amount of difference within the population. If the population is very homogeneous with respect to the characteristic you want to investigate, you don’t need a big sample size to establish a reasonable estimate of the characteristic. In statistical terms, this factor is measured by the standard deviation of the population characteristic (or a good estimate thereof).
• Confidence: the amount of risk you are willing to take to reach false conclusions. This factor comes in two tastes. The first is to reach the conclusion that your research hypothesis is true, while in fact it is false. The second is the risk you take to say that the research hypothesis is false, while in fact it is true. These factors are statistically translated as alpha and beta. The smaller you want the risk to be, the higher a sample size you need.
• Tolerance: How big a difference actually makes a difference for you? Suppose you have two mean values for a certain population characteristic: 10.2 and 10.23. Does this make sense, translated to your real world? Will you act differently for both groups? The smaller the difference you’re interested in, the more samples you will need.

The way you need to interpret these three factors depends on the type of research you want to perform. The next section handles the subject of the analysis type.

Type of analysis

Sample size calculator offers you two main dimensions of analysis, each with 2 values:

Means versus proportions: a single characteristic versus the difference between two characteristics

This amounts to four different kinds of analysis used in research:

• Estimating a single mean
• Concluding there is a difference between two means (or not)
• Estimating a single proportion
• Concluding there is a difference between two proportions (or not)

The example found below this page describes a real world example of the type of research you selected, to help you relating to your real world.

General values

Alpha

Sample Size Calculator - Values and settings

Suppose your research hypothesis is that people in London earn more money than people in Dublin. You take a sample of each population, and average the income.

The result is that Londoners earn £2 more than Dubliners, but the difference is too small to be significant. So your conclusion is that Londoners do not earn more money than Dubliners.

In fact, your conclusions may be incorrect due to bad luck. Especially with high variance in the population and a small sample size, you take the risk of researching non-representative samples.

Alpha is defined as “the probability that you conclude your research hypothesis (Londoners earn more than Dubliners) is false while in fact it is true”.

Population size

If the population size is small compared to the sample size, a correction for finite populations applies.

You don’t need to asses the size of your population very precisely unless the sample size is indeed large compared to the population size (say, 20% or higher). If your population is large, it doesn’t matter how big precisely.

Response %

In survey research, the respons rate is usually far from 100%. A percentage between 30 and 70 is considered normal.

Tolerance

Tolerance needs to be interpreted differently for the estimating a single characteristic versus concluding about differences between two characteristics:

Single characteristic: in what interval (2 x tolerance) do you want the estimation to be? The narrower you want this interval, the more samples you will need. For example, it requires less samples to conclude some mean lies in the interval [2-10] than you need to conclude the mean lies in the interval [5.1-5.3].
Difference between characteristics: How big a difference really makes a difference for you? Suppose two proportions from two different groups are 0.85 and 0.87. Would you treat them as two groups? Does this 0.02 difference make sense, real-world wise?
The units of the tolerance value are the same as the population characteristics value. Suppose you measure a proportion: in that case, the tolerance value would not be allowed to exceed the proportion value you expect.

Also note that the actual interval around the estimator is twice the tolerance value. For example, a tolerance value 0.5 on an estimated mean of 1 means that you conclude the true value of the mean lies in the interval [0.5-1.5]. The interval length is 1 or 2 x 0.5.

Values appropriate to means

Mean

The estimation of the mean is not used in these calculations. It only helps to interpret the numeric results in the report generated by SSC.

Standard deviation

It is important that you asses the amount of variability in the population as precisely as possible. The statistical definition of a sample standard deviation, the number you input here, is: the square root of the sum over all sample elements of squared differences between the sample element and the mean, divided by sample size minus one.

If you don’t know the variability, you can use these sources:

• Conduct a small preliminary research to asses the variability
• Use your previous research, even if not fully relevant.
• Use the literature. Other studies about the same subject often mention variances or standard deviations.
• Use standard scales for which you can guess the variance well.
• Be sure to recalculate your sample size after you have done the actual research, to asses if your original guess was reliable enough.

Values appropriate to proportions

Proportion

The proportion is used mainly for yes/no questions. For example: a business analyst wants to know how many people in a certain population are willing to invest in a new investment plan. He can use the simple yes/no question and apply the sample size calculations for proportions.

If you’re unsure about the proportion of yes-sayers, leave it at 0.5. This is the most conservative estimate.

If you suspect proportions are extreme (below .2 or above .8), use the correction for extreme proportions to avoid underestimation of your sample size.

Values appropriate to differences

Beta

Beta is the risk you take to miss an existing difference between two populations. Suppose Londoners indeed earn more than Dubliners (for example, the real difference between their average incomes is £150 per year) but due to a small sample size and high variance within each group, you find that there is no significant difference.

In that case, you would miss the real difference and draw an erroneous conclusion.

Statisticians call this the “power” of your test (power = 1 – beta): the higher you want the power to detect existing differences, the higher sample size you need.

Corrections

SSC has these corrections, which you can turn on or off:

• Extreme proportions
• Small sample sizes
• Small population
• Non-response
• One-tailed test

Sample Size Calculator - corrections

Extreme proportions

If the proportion you expect is either very high (above .8) either very low (below .2) then you need a correction factor for extreme proportions to get a better estimate of the sample size needed for single proportion estimates.

You can safely leave this option checked. SSC will use it only when necessary.

Small sample sizes

As argued by Kupper and Hafner (1989), estimating a single value suffers from underestimation of the sample size needed if the sample size itself is small. SSC uses an approximation of the Kupper/Hafner findings to correct for small sample sizes.

You can leave this option checked. If sample size becomes bigger, the correction decreases.

Small population

Most statistical tests used are developed with the assumption that the population is sampled with replacement. In practice, this is never the case: you never research the same individual twice in the same sample.

With large populations, the probability that you would investigate the same subject twice in the same sample becomes neglectible. However, if the population is quite small, it is likely you would have the same element more than once, if you’d use replacement.

Therefore, this correction factor applies. You can safely leave this option checked, unless you want to know what the underestimated effect of a small population is. 

Non-response

If not all sample elements will deliver measurements, you need to have a proportionately higher sample size to get the actual data volume you need.

Check this option only if response is below 100%.

One-tailed test

SSC defaults to a two-tailed test for its calculations. If you happen to know the direction of the effect beforehand, you can check this option to conduct one-tailed tests. 

For example, if you had reasons beforehand to believe Londoners earn more than Dubliners, you could check this option and reach a smaller sample size. On the other hand, if you do not know that Dubliners earn less, you would leave the option unchecked.

Knopenlabo is een eenvoudige tool waarmee je in een oogwenk berekent hoe sterk een touw ongeveer is.Verschillende factoren beïnvloeden namelijk de maximale en de veilige belasting (VB) van het touw:

• de touwsoort: kunstmatige touwsoorten zijn meestal veel sterker dan natuurlijke.
• het aantal kardelen (afzonderlijke strengen waaruit het touw bestaat): een driekardeels touw is meestal sterker dan vier- of vijfkardeels touw.
• de diameter: hoe groter, des te steviger.
• of het touw nat is of niet. Nat touw van natuurlijke oorsprong is veel zwakker dan droog touw.
• de kwaliteit: deze gaat achteruit bij het gebruik (sleet).
• en, niet te vergeten, de knopen in het touw. Een touw is het zwakst vlak achter de knoop. Sommige knopen behouden de breeksterkte van het touw vrij goed (90-100%). Andere verzwakken het touw in grote mate (40-60%).

KnopenLabo verwerkt al deze factoren tot een schatting van de breeksterkte van het touw. Het resultaat zijn twee getallen:

• De VB of Veilige Belasting: dit getal geeft het aantal kilogram aan waarmee je het touw kan belasten op een veilige manier.
• De maximale breeksterkte: deze geeft aan op welk punt een touw van dit soort het waarschijnlijk zal begeven.

Voorbeeld van het gebruik van knopenlabo

Het programma KnopenLabo heeft een eenvoudige interface. Je kan voor elk touw de eigenschappen en de knopen aangeven, en op “bereken” drukken om te weten hoe groot de VB en de maximale breeksterkte is.

Woordenlijst

As a coach, your role is probably a “chicken” role (remember? Pigs and chickens can attend, but only pigs can talk?) So you have to be silent, but that does not mean you’re not active. In fact, this is your best opportunity to listen actively. That is, to try to understand the true meaning of what is being discussed so that you can coach the scrum master and the team so that they become even more effective and efficiënt.

Team Interaction Picture

One little tool I have found useful when coaching a team is something I call the Team Interaction Picture (TIP). It’s easy to draw, yet you can learn a lot from it.

Here’s an example. (it’s fictitious but representative of the actual TIPs I make when observing a daily standup meeting–and every single element is based on real TIPs).

The Team Interaction Picture: an agile coaching instrument

Rainy day

It’s 2009 November 23d (a gray Monday morning) and the team has gathered around the task board in the corner of the landscape office. The place is not ideal: somewhat too small, and there is a pole and a chair which hinder access to the board and invite team members to sit down/hang around. Luckily, the team has discussed this before and nobody will use the chair.

TIP technique: draw the task board as a narrow rectangle, the team members as circles (indicate their name and if needed, their role). For absent team members, draw a striped line outside the team. Also draw any other large objects (like the pole and the chair) present.

Usually, the meeting starts at 9h30 but now they’re six minutes late because Sandy is not there yet (you know she has to bring her daughter to school).

Sandy arrives

Finally, Sandy arrives. She has had a phone call from Nancy, who is ill and won’t return before Wednesday. Sandy joins the team (they’ve already gathered around the board!) and starts with giving an update on the impediment list.

TIP technique: write date and hour of start next to the TIP diagram. Indicate the order of events with numbers and indicate the end of the standup meeting under the event list. Use the same number to indicate in what order each attendee takes the word.

Eight constructive minutes

When Sandy tells the team an old and important impediment will be solved today, Dave interrupts and says that he hopes this will be the case, since he remembers Sandy promised this the week before, and the week before that… Then there is a short discussion between Sandy and Dave, which they conclude not to continue here.

TIP technique: when person A adresses person B, draw an arrow from A to B. If B responds, draw the arrowhead next to person A. For each next discussion between A and B, draw a small perpendicular line on the arrow from A to B.

The meeting continues in a constructive way and after eight minutes, everyone is up-to-date and knows what to do for today.

Coaching the scrum master

After the meeting, I’ll have a brief word with Sandy. I ask her opinion and we compare. Here’s how I use the TIP:

• General conclusion: a constructive meeting that respected the 15 minutes timebox (even if it started late, no problem here because even then the meeting ended before 9h45).
• Is it possible to remove the chair so that there is more space and better access to the board? Maybe, but Sandy will talk about the idea in tomorrows standup.
• Starting with the update on the impediment list (especially if there is good news) is a good practice. It helps to prove to the team that the scrum master is there to help them, not to command&control.
• Team dynamics are determined for a large part by the interaction of Dave and Sandy. Sarah occasionally tries to interrupt, but Sandy does not answer.
• Jeff, a junior team member, never takes the word unless he gets the talking stick. Even then he does not really talk, he just indicates on the task board what user story he will work on and that’s it.

Especially the last two topics might be sensitive, since they can indicate there’s an underlying problem. It’s dangerous to draw conclusions from one eight-minute meeting, so I would compare my TIP with the TIPs of two or three other meetings.

But in any case, I have a good graphical representation of what happened during this standup meeting. The team might even be able to use my TIPs during the evaluation meeting so that they can see how they interact.

For readers who use this TIP: please share your experiences by replying to this post. Thanks!

The factsoak learning model

Factsoak uses a unique model of learning to assist the learning process of all facts, including:

• Foreign languages
• Special terms
• Abbreviation lists
• Historical dates
• and all other facts

Two modes

Factsoak supports two learning modes. The most effective learning takes place when you alter between these modes in five to ten minute intervals:

• Training mode: Factsoak will present you a fact, wait, and present the explanation. The frequency of presentation depends on the difficulty of a fact. You can adapt the speed of presentation and the direction (from fact to explanation, from explanation to fact, or both).
• Test mode: Factsoak will present you with a fact and ask the explanation and repeat this process a number of times. After the test, you get a result and a list of errors. For questions you were able to answer, the difficulty of the fact will decrease. If you did not solve the question, its difficulty will increase

By alternating between training and test mode, you will be presented with those facts that are most difficult to master. Factsoak will also express your mastery of the facts as a percentage. When mastery is 100%, you’ve reached your learning goal.

The actual probabilities that werewolves win are difficult if not impossible to calculate since this depends on several factors. The most important ones are:

• the existence of special roles, such as the seeer, the witch, the possessed,…
• how well the players (especially the werewolves and special characters like the seeer) can play their role, i.e. how well they can prevent the other players from having information on who they are.
• the interaction between the above factors.

If we make some assumptions, calculating the probabilities is possible (see figure):

• no special roles: only werewolves and villagers are allowed. This boils down to using the vanilla rules.
• no information: villagers do not have any information on who the wolves are, so they vote randomly.
• optimal play for werewolves (i.e. werewolves don’t vote for each other)

How to choose the number of werewolves?

If both parties, werewolves and villagers, have an equal chance to win, the game is most fun. Up to 17 players, a lone wolf is the best choice. From 18 players on, two wolves are needed. From 44 players, 3 werewolves have about an equal chance to win. Four wolves are needed to play in a game with 86 players, five in a game with 140 players and six in a rather massive game with 210 players.

Probability of a win for the werewolves, given their number and the number of villagers, under the vanilla rules and assuming no information and perfect play.

The sawtooth-effect

An astonishing result is what I call the sawtooth-effect. Increasing the number of villagers by one can actually decrease the probability that they win the game. How is that possible?

Suppose we have one werewolf and three villagers. The probability that the lone wolf wins the game is 2/3. Why?

During the first night, the werewolf will eat one victim. In the morning, the number of villagers is 2. They will hang one person. Chances are 1 in 3 that this is a werewolf. If the two villagers hang the werewolf, they win the game. If not, a daytime massacre occurs and the werewolf wins. So the probability of win for a lone wolf against three villagers is 1-(1/3)=2/3.

Now we increase the number of villagers to 4. The probability of win for the wolves is then 3/4, which is considerably higher than the chance to win with one villager less. Why?

During the first night, the wolf will eat a victim. In the morning, only three villagers and one wolf are left. The villagers hang one player randomly, so they have 1 chance out of 4 to hang the werewolf.

If they do, they win (probability = 1/4). If they don’t, they hang a fellow citizen and the wolf will eat one victim during the night. Only one villager and one werewolf survive. The sun rises, and the wolf will organize a daytime massacre…

So the source of the sawtooth-effect is this: the probability of hanging the wrong guy is higher when there are more innocent persons around.

Ten quasi-perfect games of werewolf

With 100 players or less, the perfect game (probabilities of winning for both parties exactly 50-50) does not exist.

These ten games come closest (indicated before the colon is the probability of werewolves winning):

• 0,5016: 24 players of which 2 werewolves
• 0,5040: 35 players of which 2 werewolves
• 0,5059: 52 players of which 3 werewolves
• 0,4952: 54 players of which 3 werewolves
• 0,5060: 73 players of which 3 werewolves
• 0,5040: 75 players of which 3 werewolves
• 0,4941: 77 players of which 3 werewolves
• 0,5045: 92 players of which 4 werewolves
• 0,4996: 94 players of which 4 werewolves
• 0,4947: 96 players of which 4 werewolves

Depending on your sport or fitness goal, you should train with different heart rates. When sporting, wear a heart rate monitor suited for your sport and stay in the right training zone:

• Zone 1: at this level, you will increase your fitness level without risking to get overtrained. You should start at this level when you are a beginner or when you did not take exercise during a long time. Even when training at this level, you will lose weight.
• Zone 2: this zone will take your cardiovascular fitness to a new height. The heart will become more efficient in pumping blood and the muscles will become better at taking oxygen from the blood stream.
• Zone 3: this zone is often called the “target heart frequency zone”. Training in this zone improves the cardiovascular fitness and the capacity of the body to consume energy and release waste products. Also the general muscle strength will increase.
• Zone 4: in this zone lies the anaerobic threshold, the level at which is becomes difficult for the body to consume enough oxygen and to release waste products. Muscles will fill with lactic acid when training too long in this zone. Most athletes can compete at about this level. Training at this level should be done only for short periods of time and with advice from a doctor.
• Zone 5: this zone is the maximum your body can do. It is useful if you are an athlete trying to increase speed. Stay away from this zone unless you are in optimal fitness and with medical advice.

How to use the training zone calculator

Freeware training zones calculator

Determine your Rest Heart Rate (RHR): this is the lowest heart rate under normal circumstances. The best time to measure your RHR is before you get out of bed in the morning. Measure your heart rate for 30 seconds and multiply the result by 2.

Determine your Maximum Heart Rate (MHR): this is the highest heart rate your body can deliver. It should be done by a professional (sports doctor).

If you cannot consult a doctor, you can also estimate your MHR by providing the training zone calculator the following information:

• Age: generally, the higher your age, the lower the MHR.
• Sex: generally, males have a slightly higher MHR than females.
• Weight: the heavier, the lower the MHR.

Simply provide the Fitness Zone Calculator with the right data and it will calculate your personal estimated training zone levels (min and max heartbeat for each zone).

Hover over the zone labels to get a short description with each zone.

When following a training plan, do not forget to reestablish your resting heart rate from time to time. An increased RHR signals you are overtraining, a decreasing RHR tells you you are on the right track to become a fitter person. Success!
