Happy new year! Hope you’re all full of good food, nice feelings and excitement to come back to what you do best :)
Today I will give you a simple tool – a poster that you can give to your teams, that can really help.
Few years ago, on a conference I met a great guy – his name was Chris Avery. He mainly works with leaders and high-level management. He introduced me to his Responsibility Process, which I really like. It’s based on a model that you can use in your daily work. And if you’d like to know more visit his website.
So what is this all about? Simply: about responsibility. In English, there are two words very close to each other, but with a major distinction. I noticed that not only in Polish, but also in many other languages Responsibility and Accountability are the same word. So please, check in your language if this isn’t the case. And if is, stress the difference on every occasion!
So why a model or a process? Can’t a person just be responsible? It’s a little more complex than that. Children learn responsibility as they grow up and experience more. As adults we can also go through this process every time something happens. So let me explain how it works with an example – I lost my keys.
Quit – you can always quit and just not solve the problem. In the case of losing keys, I would call my boyfriend and say I’m stating with him tonight.
“No, no no! I couldn’t have lost those keys!” – I rummage through my purse again and again with hope of finding it. Denial is basically a refusal to admit something happened. Kids would go with “It’s not broken” when confronted with a broken vase.
“This stupid cashier! She was so abrasive, I must have lost those keys because of her!” – this level usually involves some anger. With kids “He/She did it!” is very popular. Basically you blame someone else.
“It was raining, it was dark, all the stuff was heavy, because all of this I lost those keys” – I am trying to justify that there was no other way, I must have lost those keys. With kids it would be “It happened itself!”. We are trying to lay blame on all natural or supernatural powers we can imagine. But still we don’t admit it may be us.
“I’m so stupid, I lost those keys again …” – I am blaming myself. Nothing good comes out of it, I just bring some bad mood on myself. Kids who admit they did something bad, are usually taught to feel ashamed “Shame on you!”. It’s a step forward, at least we admit there is some of our fault. But still, nothing gets fixed.
Also known as “Accountability”. “Man, I lost those keys, so I HAVE TO call that witch, landlord again… and I’m so bad on the phone”. If you feel you have to do something, but for some reason you don’t really feel like it, that’s obligation. Obligation towards your boss or yourself. Kids usually go with “My mom/dad told me to”. You fix the problem, but out of necessity, not because you want to.
This is the highest level. You don’t look at whose fault that is. You don’t blame yourself. It happened – sh*t happens. “[phone rings] Honey, can I come by your place to pick up my spare keys? I just lost mine. – Thanks, bye!” – something happened? Just go and fix it. That’s responsibility. Doesn’t matter if there were 0,00003% of your fault. Just do it. With intrinsic motivation, not being coerced.
Every person has a certain level of responsibility in specific areas of life. For example – your love life, you can be on the Shame level. You blame yourself for everything that happens. Or you can be on Lay Blame at work – “It’s their fault” or “That’s not my job, it’s theirs”. Usually with your kids, you’re always Responsible. You can also change the level you’re on. Up or down.
Most important thing about this model is that you can’t impose it on anyone. It has to be their decision. When using it as a team, you can post a poster on the wall and whenever someone says “It’s not my job” you can ask – what level was this comment on? Works like a charm :)
Hello again :)
Just like I promised – the second Toolkit post is 2 weeks later. Just click on the tag, it will show you all the toolkit posts.
Today I wanted to show you how humans differ from other living creatures and why we should take advantage of that in our work.
First, we have to understand what Power is. One major thing about power is that only you can grant someone else power over yourself. Sometimes it’s in exchange for something, sometimes it’s just because you want to. Let’s take an extreme case – you have a knife on your throat. Someone holding it demands you do something. You still have a choice whether you do it or not. The price is high, but still, it’s your decision.
So let’s take a look what kinds of power are there, and what benefits they bring.
1&2 – Rewarding & Coercive
These two forms are the most common in nature. Every animal is susceptible to those. Basically they mean that you can do something for someone in order to receive a reward or avoid punishment. This is exactly the carrot & stick. If you use this power, you will get obedience. But nothing more. So if you want your dog to obey, you can give him or her treats to reinforce good behavior and punish bad. But remember, even if you do that , you might not be able to take control over your dog. Because when you turn around, the sausage will still disappear. Exactly the same applies to humans. If you reward and punish, everything will go towards what you reward and what you punish will be hidden. But apart from that, no creativity can be expected.
3 – Given/Formal/Legitimate
This power is only present in creatures who build societies. Did you ever watch The Dog Whisperer with Cesar Millan? If you did, try to remember what he wanted to achieve. He was the Pack Leader for the dog and taught owners how to do the same. He wanted the dog to be submissive. And this is exactly what you will have if you have formal power over someone – like a manager or a police officer. Someone who is high in social ranks, somehow culturally above someone else. But if you operate with this power, you will have submission and submission only. There is still very little creativity involved.
Expert power is something that can be described as being respected, because you know a lot or can do something. This is something that has not been observed in any creatures, besides human. Some researchers believe dolphins, elephants, apes and crows may exhibit that power as well, but no hard proof has been found yet. Working with someone with that power over you, gives you wings to learn. You want to become just like this example someone, so you listen, follow footsteps and try to master this subject. This power gives you learning and conquering difficulties.
This is a power that’s closest to trust. In large quantities it’s perceived as Charisma. It’s something that produces good feelings and engagement. It’s a power that’s easiest to lose and hardest to gain. You feel that this person is just right, you follow their lead. It’s something good leaders have.
Why is there an asterisk here? Because this power was added later on, it wasn’t in the original research. This is a power that is present only in informational societies. Where having, withholding or manipulating information is possible. Some also argue if this is not only a different manifestation of a rewarding or coercive power. I will leave it for your consideration.
So why should I bother knowing this?
Because the higher the power number is, the harder it is to gain, but the bigger the benefits are. It’s easy to coerce someone to do something, threatening them to sack them or promising a yearly bonus.
Also because coercive and rewarding powers are encoded in our reptilian brain, they are our instincts and it’s extremely hard in a critical situation not to use them. Same applies to given power – only if you give in to your instincts, the more primitive one will take over – the carrot and the stick.
And in critical situations we need creativity, learning and engagement the most – to quickly get out of that crisis.
That’s why Scrum Masters have to have Expert and Referent power but not formal, coercive or rewarding ones. So that they can get the most of people any time.
Use this knowledge wisely :)
Hi Everyone :)
Today I am starting a new series. We’ll see how regularly I will be able to update it, but the two posts will be there before Christmas.
So why a Scrum Master’s toolkit? Because lots of SM’s and managers/leaders who would like to build better Teams and Scrum Teams struggle with good sources of knowledge. Of course there is Patrick Leoncioni, the Heath brothers, Tom DeMarco, Esther Derby, Diana Larssen, Lyssa Adkins, Seth Godin, Steve Denning, Ken Schwaber, Ken Blanchard, John Kotter, Jurgen Appelo, Uncle Bob, and many, many others. You can read all of their books, and actually you should. But what about someone that has just started working as a SM or a manager? They should start assembling their own understanding-and-exercising toolkit right away and I would like to give them a digest and a direction where they should go. And to point more experienced ones into terrains they may have never explored before.
Let’s start with one of the most important models for knowledge and skill development. Many know about the SHU-HA-RI model. Good! If you don’t then go ahead and google it. Or not J. The Dreyfus Model is the SHU-HA-RI extended and for me way better explained.
Where did this model come from? In the ‘70s (maybe even ‘60s) of the past century, brothers Dreyfus worked with pilots.
As you can imagine, simulators, just like pilot schools have today were not invented yet. So there had to be some other way of knowing whether a pilot knows enough no to kill their passengers when something bad will happen mid-air. They observed lots of people and finally in 1980 they published a paper where they summed up everything they knew.
So let me explain how the model works. I will use an example that most of us can relate to: learning how to drive.
You start learning how to drive with your instructor, parent, guardian or sibling. Take a moment how it felt – clutch, gearbox, safety belts, blinkers, wipers, RPMs, speed, the sound of the engine, the big metal box you just sat in to operate. A lot to take in. And a lot of rules: when you change the gear, push the clutch. Release it slowly. Blinker! There is a 40 speed limit here. At this speed change the gear. Lights! … and so on. You were so consumed with getting to know the rules, you needed someone to remind you about some of them you were just currently not concentrating on.
This is the moment when you start to grasp it. Your leg automatically pushes the clutch when you’re changing gears, you don’t even think about the blinker, you just turn it on, sometimes even when you don’t need it. Seatbelt? Automatic when you sit behind the wheel. Mirrors? You know what they are for. But wait. Now, because your processor load with all the mechanics is off, you start seeing the environment around you. You actually see the road signs your instructor was telling you about. You remember here is a 40 speed limit, but suddenly you understand why – there is a sign!
But wait, there is more – there is traffic! There are other people! They are DRIVING! You suddenly start noticing the environment. It doesn’t happen at once of course, but gradually. But this is when you’re not a novice anymore. You gain perception of the environment.
This is when you just drive. You got your license some time ago, you know your way around town. You don’t worry about operating the car anymore, you just do it automatically and it just listens to what you want to do, not how you want to do it. You drive confidently and you can actually predict what will happen in simple situations. A car coming too fast from a street on your right? You just slow down and watch him closely. Someone isn’t going at a straight line? He may be intoxicated, let’s pay close attention and maybe call 112/911. Rules are in your blood, you can see the environment and you can envision negative consequences of breaking those rules. This is what a competent driver does.
Proficient would be an experienced driver. Not their first car, they drove quite a few. Maybe even other vehicles. They have their license for 6, 10, 15 years now. Not only they can envision consequences of breaking the rules, but they bend them and understand why. They can predict even complex situations they have never seen before. For example, a truck driver starts slowly turning left. Something’s not right. That driver may not be aware what is wrong, but his brain will know and put him in high-alert mode. He will be able to predict what speed limit will is where, even without looking at the signs. He may not even remember it. He also may bend the rules – speed limit? RPM limit on that gear? Getting out of skidding? The fact that you have to speed up to do this, may be incomprehensible for a less proficient driver. So a proficient one automatically sees that something’s wrong and bends rules understanding what it brings.
Most of us will not be experts. WRC drivers or F1 drivers would be experts. Professional truck drivers would. These people intentionally break the rules to achieve something more. And they risk a lot with it. Regular drivers may not be able to operate in an environment when your car weighs 30 tons and you have 2 gearboxes and 20 gears at your disposal. Or when you have to speed up to 130 KM/h to be able to turn. This is the environment where only experts can go.
They also sometimes have kind of supernatural powers. There is a story of an F1 driver that just stopped in the middle of a race. He couldn’t explain why he did that. There were high walls on the track with fans on the top that could see all the action. Drivers couldn’t see more than few
hundred meters ahead. But he just stopped – and as it came out – it saved his life. Right around the corner there was a huge accident, involving several cars. Later everyone started wondering – how did he do that? Does he have some supernatural powers? After further analysis of the footage from the race, it came out that he must have seen the crowd on the top of the fence – they weren’t cheering, as usual, they were looking to their right. He must have spotted it with a corner of his eye and his body just reacted, braking and stopping right before it. It saved lives of few other drivers behind him too. Unfortunately I was unable to find the name of this driver. Maybe someone can help me here?
But there is a catch in all this. Do you know when young drivers crash the most? 6 months after getting their license. Why? Because of the Dunning-Kruger effect. You are still a beginner, or start being competent, but you think you’re an expert already. That’s when you start breaking the rules and you either crash or break the engine, or the gearbox. Because you don’t understand consequences as well as an expert would. If you are aware of this effect, you can act.
If you are a Scrum Master, you can watch for that in your team. If they are introducing Scrum for example and after 3 sprints they decide to ditch the Review, you can see the Dunning-Kruger effect is happening. And you can tell then why they should wait a little more, until they actually see the environment.
It applies to everything. Learning to play an instrument, cooking, programming, drawing, simply everything.
It will help :)
Disclaimer: opinions expressed in this post are not meant to offend anyone; they are highly subjective and based on my own experiences.
Just yesterday @thels6 pointed me to a blog post by @pawelbrodzinski on women in IT. Looks like my opinion is sought after :)
I have read this post and the preceding one few times and the only sure thing here is I cannot take a side. Let me explain by scratching the surface of the subject in the longest pos I have written on this blog so far.
Availability of IT girls on Polish market
Let’s start with a story from some years ago, when I was seeking a job as a junior developer, right out of studies. A male friend did the same at the same time. We finished the same school, had almost exactly the same experience (I even had a little more) and tried finding a job in the same city. Result? He sent 12 applications, had three interviews and in 2 months he was in. I sent 96 applications, had 5 interviews (3 of them in the same company) and it took me over 6 months to start working. And later I found out that it was only my experience as a manager and some leadership traits that got me this position. It did occur to me that maybe I was just a lousy developer, but I passed all technical tests and interviews. Especially when I was talking to my female friend who had a similar experience few years back – this time it was 2 vs. 20 with her male friend. Third girl confirmed same scenario few months later. So I’m not alone.
Same situation from another perspective: as a manager I observed good influence of girls on teams, so I was very happy when my team asked for one. Hundreds of CVs, dozens of interviews and a total of female candidates: 3. One of them didn’t know what a hexadecimal is, second didn’t show for an interview and the third one failed at writing an algorithm for a Fibonacci sequence. Finally I was able to get girls, but only via friends already on the team or scavenging from a dismantled project.
Why is that? And this is my subjective view:
Girls are really rare in IT in Poland. In one of the corporations I worked with, girls made 11% of the staff, including HR and administration. This is freakishly low. During my studies I was one with 76 guys. There was another girl, but it was temporary.
What I observed was that girls are either brilliant and they excel at almost everything or are just ones trying to go through unsuitable studies to find a husband (and it’s not as rare as one may think). So if there is a team that catches the brilliant one, they refuse to let her go regardless of the price. The rest is just the ones that somehow got through the IT studies and now are looking for any job.
Taking this into account look at the cultural implications of a tradition where a woman cannot learn engineering or maths because she is believed to be genetically impaired towards this knowledge. Once in few hundred there is that one girl who is encouraged by parents to pursue what she was good at, wasn’t brilliant, but good. This is a phenomenon employers don’t really know, thus are afraid of it – will she be as bad as the other girls? Should I risk the simplicity of the male hierarchy for her?
Best are headhunted, worst are suspended between employers. No wonder there is almost no valuable female material on the market. And if there is, it’s a pure gemstone, nobody knows what to do with.
Team building, engineering and too much good stuff
If you come to an open space of a corporation, wander a little and listen you can hear an interesting correlation: if there is a space or a room with no women, the frequency of swearwords is significantly greater. If you introduce a girl to this team, the intensity and frequency of these words diminishes. I have observed this in three corporations in Poland, each one affiliated with a different country, so looks like this is not a factor.
Second thing I observed was the decision making process. Girls acted as catalysts and there were two types – the fighters and the quiet ones. The fighters stood up to what they believed in and argued their point until either they won or someone came up with something better. The quiet type just sat there in silence for the majority of the meeting, but the moment she opens her mouth, everyone goes silent. Her opinion and expertise is extremely valued. In both cases the impact on decisions made was positive – less quarrel later on and braver ideas, but better thought through.
So why I prefer to work with men rather than women? I like to have a female friend in a group, but not too many. Why? Let me tell you another story.
A professor in my negotiations class once conducted an experiment. At first it was supposed to be a joke, but it turned out to be scientifically interesting. The experiment exercise was based on two groups of interests – fruit growers and producers of local vodka. Both, not knowing what the goals of the others are, where supposed to gather points that were later summed up by the agreement they all signed. The maximum amount of points a group could gather was around 20.
The control group consisted of few groups of mixed gender: 2+1, 1+2 and 2+2. In these cases negotiations took between 20 and 40 minutes, and the producers beat growers by around 5 points, resulting in average in 8 vs. 13. So the exercise was skewed somewhat towards the producers, rather than growers. Then professor started dividing groups by gender and giving them same exercise.
When both groups consisted of men, the negotiations took less than 20 minutes each time, resulting in low scores for both. Guys just quickly agreed on something and left to take a break. Scores almost never exceeded 10 points, regardless of the side.
If there was girls vs. boys group, girls almost always crushed boys. It was very hard to get a negative score in this exercise, but somehow guys managed to do this few times.
But when there were girls vs. girls, there was fire. The competitive nature of women showed – only few groups managed to finish within the class time (1.5 hour) and the score was about the same as the control group. So no gain here, just more smoke.
Why was that? My explanation is that women’s competitiveness and attention to detail resulted in discussing and quarrelling about every little thing there was to discuss. Men looked at the broader picture and strived towards a common goal of having a longer break in the end of the class.
Looking at this exercise and my observations I believe the healthiest groups are mixed ones. Don’t strive for too many girls – they may impede the course of work.
In addition in 2010 or 2011 in HBR there was a study published that analyzed gender distribution on executive boards of big companies. The interesting thing was that the more women, the better, but if there was more than three, the correlation stopped. Generally the executive boards with up to 3 women generated about 11% more revenue, but with 4 or more it was less (I couldn’t find the article online, I will scan my paper archive if someone is interested).
It all corresponds with what Anita Woolley wrote, I’m only curious about the team sizes she researched. Teams with women on them tend to do better, because of their emotional intelligence and instincts they naturally facilitate group discussions and create a bond in a team. They also increase the mutual respect. As long as someone else doesn’t show up in the same dress ;)
Cultures and countries
All my observations concern Poland and our cultural implications. I suspect there is a major difference between how women are perceived and what impact do they have in Poland and outside it and I had some opportunities to observe it – mainly in USA and India, but also in Finland and Austria. There are two major differences I wanted to point out.
First – general cultural perception. In Poland it’s customary to let a woman though the door first, to help her with an obstacle, not let her carry heavy stuff, introduce yourself first and things like this. It’s absent or barely present abroad.
Second – treating women seriously. And this is a huge problem I’m observing. If a girl is just standing there, looking good or mingling, all is great, she is respected and adored. When she is an expert in something, she has to work three times as hard to prove herself. It takes me way more time to prove I have something interesting to contribute than my male friends. Same happens with my female technical friends. Unless we have been introduced by someone that knows us, we have to wrestle someone down or prove someone wrong before being respected in a male group. This is exceptionally visible in conventions and conferences. I also talked with two transgender professionals and they both agreed that their life became harder as experts when they became women.
And again – this is something I failed to observe or was barely there in the countries I mentioned above. It was completely non-existent in India, where women make 50% of the staff and are encouraged by their male colleagues to pursue what they are good at. Interestingly it’s generally testing, but I attribute it to the attention to detail and ability to multitask.
Employ girls. But not at any price and every single one. Treat them equally – look for your own bias, if there is one, but don’t choose a girl if she is a worse candidate. I once was lured by the prospect of diversity in a team and failed.
Girls in teams rock – just don’t compose a team solely out of girls.
And for the technical discussion – forget there is a difference in gender as hard as it may sound.
Girls – don’t wear red to work or to an interview. Unless you want to be subconsciously perceived as an object or a beautiful background by all straight men around. It’s in human nature and you can’t overrun it with the most impressive technical demonstration.
So here we are, the team is doing fine, and they fixed all of their major problems, so why conduct a revolution?
Scrum is a fantastic tool for enabling agile; making sure everyone gets the mechanics and bringing some order into chaos. And that’s what happened. So, if we have an understanding team who knows what they are doing, Scrum is not needed anymore. It’s too heavy for flowing work. Since they fixed everything big, the system went into the maintenance mode. No large functionalities were to be added, mainly small elements, configuration and fixes. New technologies were supposed to be supported by a new solution currently built next door.
Optimization kicked in. Let’s see what they did. First, they visited the admins team (exactly this one: Combining Kanban and Scrum) and made themselves familiar with what they came up with. Their conclusions led to a nice Scrum-Kanban hybrid that was becoming lighter and lighter every week.
First, they took the sprint backlog out. It was kept in an electronic form on a server so that clients could see, but it proved to be useless to them, so the team decided to take up a physical board. Boy, I wish I had a picture – a fantastic, color coded board, with magnets, people and an impressive palm tree on the back. Suddenly everything became clear and people had a nice excuse to stand up and stretch :)
Second change was sprints – they resigned from them and started the morning 15 minute plannings and daily standups mashup. Soon they took no more than 15 minutes together.
Their work started flowing, but they never forgot about retrospectives. They were as regular as ever – every week, in the meeting room.
Soon they started lowering the WIP limits on their work and introducing some new people to the team.
Their lead time started to drop and improvements came into place.
But then this is not a fairy tale either. Someone from the management didn’t like that this team was different. Few months later they were forced to go back to Scrum. It wasn’t bad, but it was a heavy process after months of the lightest framework they could imagine. Later it came out that the management needed more visibility, because the system that was supposed to replace this one failed. And of course this system is still supported and works fine :)
So why did they adopt Kanban and why it worked?
First – they knew what they were doing. They worked through a tough time together and became a strong team able to self-organize.
Second – it was their conscious decision. Nobody forced this solution on them.
Third – they drove their own transition. I only supported their efforts. This way they were in control and could probe what worked and what didn’t.
Fourth – they learned from other’s mistakes – the first thing they did was to visit a team that did something similar and exchange experiences.
When estimating as a group, the team tends to be more accurate than an individual. The phenomenon known as the Wisdom Of The Crowd is a renowned effect widely used in multiple industries. This effect is especially strong when dealing with estimation of size.
Everyone working with a Scrum Team can benefit from using the Planning Card Game. Main applications are estimating size and value of Product Backlog Items, but are not limited to them. Teams estimating benefit in exchanging knowledge and the Product Owner benefits from values produced while playing.
Choosing estimation units
Before the estimation can begin, the estimating group has to choose their estimation unit. Units can be divided into two main groups – absolute and relative.
It is possible to use the Planning Card Game using absolute units, but it has been observed that those units tend to turn into relative ones creating confusion of what they actually stand for (the Relativity Effect described below).
Humans in general tend to underestimate work when asked for an absolute value, for example hours or currency. Also if using those, the work has to be re-estimated often as the team learns new things and can complete tasks in shorter time period. This time is actually wasted.
Relative estimation units are more natural. The chain of thought of human brain, even if estimating in absolute units, contains relative estimation implicitly. When asked to give hourly estimate, we first try to find something similar that we completed and then give the relative value.
Using relative units, like Story points we have to remember that they vary from team to team and are not comparable between them. They require a probation period, usually in the form of the first (or few) Sprint before they can be used for costing and future projections with reasonable error margin.
The process of estimation in form of the Planning Card Game takes a higher amount of man hours compared to estimates delivered by a single specialist, but it’s given in shorter time period and tends to be significantly more accurate.
If the team acquires a new skill and they are able to complete requirements in shorter time there is no need for re-estimation. Units are still relative to each other and it will be reflected in greater velocity.
To begin playing The Planning Card Game it is essential to create a deck that would address possible dysfunctions and reinforce desired behaviors. For example, adding a ½ card in a deck used by a team with lots of people with attention to detail might lead into endless discussions whether an item should be a ½ or a 1. On the other hand if the team prefers to break items into very small pieces a ½ can be a desired figure.
Fibonacci Sequence and variations
The basic deck for the planning game consists of: 1,2,3,5,8 and 13. Some teams decide on extending it up by 20, 21, 35, 40, 44, 60 and so on.
Very large and infinity cards
Most commercial decks contain values up to ~40 and then a card marked as an infinity or a “BIG” which means that the item is too big to estimate it with a reasonable probability.
Half and Zero
Some decks contain “0”, which is used to mark that there is no work needed to perform to add this functionality. Usually it was done accidentally or is included in another item. Another value in the deck is a ½ – it’s used exactly like other numerical values.
It’s mainly used when playing long games (for example initial estimations of the whole project). Coffee indicates a need for a break.
Another variation is a question mark, which is widely used, especially with teams that grow, change members often, or where skill sets are very distinctive. It’s used to indicate “I have no idea how big this item might be”. When having this card in the deck, game does not stop even when someone does not know anything about the subject. It also reduces the “safe five effect” This card is especially useful for increasing cross-functionality for the team. The person using it acts as a probe for people knowing the subject more. If they are able to understand and estimate the item, it has been clearly described and doubts have been removed.
This card can be inserted instead of the infinity. It states that the item is either too big, too complex or needs to be broken down or investigated in order to proceed.
There are also decks that consist of T-Shirt sizes (… XS, S, M, L, XL …), are the powers of two or basic numbers. Teams can also use classic playing cards.
Example numerical decks:
0, ½ , 1, 2, 3, 5, 8, 13, 20, 40, 60, 100, ?, ∞
0, 1, 2, 3, 5, 8, 13, 21, 44, ?, ∞
1, 2, 3, 5, 8, 13, 21, 100, ?, Coffee
Playing the game
The process is simple.
- The Product Backlog item to be estimated is presented and explained roughly.
- Each estimator places one card out of his/her hand face down on the table.
- When everyone has a card on the table, they are all flipped at once.
- If all of the cards are identical, the estimate is valid. If there are differences, person with the highest and lowest number explains why did he/she choose this estimate.
- After explanations there is another round. Again the highest and lowest estimate should be explained, but the moderator should concentrate on people that changed their estimate and investigate why.
- Continue rounds until all estimates are the same. Value might be modified when item is already completed.
Safe Five Effect
The Safe Five Effect – it’s an effect that exhibits itself with a huge amount of fives in the estimated list. It can be caused by the fact that some team members are unfamiliar with either the domain or technology and they play a five each time to minimize the probability of being far off from other team members’ estimates.
If there are two adjacent numbers being shown for two or more rounds, for example a five and an eight, the team should accept a higher estimate. This is a safer way – in case the negative scenario happens, the estimate is correct.
In the process of playing it is forbidden to give hints on the size before the first round of estimates is revealed. If someone says “it’s easy”, especially a technical expert, whole team’s perception of the subject will then be shifted towards the suggestion and the valuable discussion will not occur.
When the Planning Card Game is used with absolute units, they can turn relative after some time. It can be spotted by the fact that the team burns more hours or man-days in a sprint than there is physically available. This effect is not necessarily negative, but it is recommended that if it occurs, the name of the unit to be changed.
The game usually results in adding details to estimated items and changing some of them as more is uncovered in the discussion. It might also result in questions that have not been asked during the initial specification of items.
The Planning Card Game brings value to the Product Owner in form of the basis for further planning and costing.
The value to the Development Team is different. Although being aware of their velocity can be beneficial, the real power lays with the process of playing. While explaining estimates, the team experiences knowledge transfer among people with different skill sets. In addition some Product Backlog Items are clarified further, or lack of certain information is exposed, so that they can be provided later.
