The tweet about this, this is my Twitter handle, and of course the tags, Reluptions, Angelina 2019, and Business Agility, which is a tag for today. We prefer not to just talk about us when we talk about just how good we are and everything. We're standing on the shoulders of a lot of people. So first of all... Chris, Matt and Olaf Mason invented Reluptions. And we talk about C. Freeman, who gave us some ideas on some tweets about Reluptions. Below we have Kunvan Aksem, who's a Belgium guy, where we are from, who invented dimensional planning, what we'll talk about as well. Nash, who's there, who gave us... Oh, sorry, Hegel does not Hegel. Nash, who gave us some things about India that we're going to talk later on. Jürgen, who's there, Jürgen the Smet, who co-created this presentation with me some 10 years ago. If I have the opportunity to bring back... Who worked with XP? Who knows a little bit about XP? A few people. If we have time to bring back XP, I take the opportunity. So Ken Begg is there, below George Dinvidy, who brought some things there that we'll talk about as well. He gave a very strange commercial. And then on top, Keke Hayatan. So we have an opportunity, we'll talk briefly about prints. Inge Gurgon, who brought us the Reluptions mantra that we'll bring. Then below we have Anat Ahmad, who gave us an interesting picture that we're going to use. Where are we? Brian Marek, if you know him, the most famous quote we'll use today. Woody, I'm not sure if he's in the room, he's somewhere here today. Who gave us some interesting tweets that we'll talk about. Same thing with Keter, who improved our slides. Working on a book, an audio version of a book with Vasco, who gave us in the preparation a lot of IDs. Had he had bones on? My mother. She brought some IDs, so you can see we'll talk about some of these things. Georg, if you ever meet her, she's one of the people who, if she understands an ID, she asks much more questions and she's able to explain it way better than the people who actually invented these things. So I learned a lot about real options from her. Okay, sorry? The goal from this presentation is to inspire you. Yeah, so we are not going to give you solutions to certain problems. We want to inspire you so that you can have IDs and that you can solve your own problems.  Correctly. We're going to start out with the real options mantra. That means that we're not going to explain immediately everything that we'll talk about. We'll just learn you the mantra and then later on in the presentation we'll teach you what they mean. So Hekka, here you go. Options have value. Options expire. Never commit early unless you know why. This is going to repeat. So the goal is that you also help out her with the mantra. So please help out and shout out together with her. One, two, three. Options have value. Options expire. Never commit early unless you know why. Was that okay or can they do better? They can do better. Okay, let's try. One, two, three. Options have value. Options expire. Never commit early unless you know why. Is that okay? That's okay, okay. Yeah. That in the mantra there was commitment and there was option. What's the difference? Great question. I pointed that back to Twitter and this was Hekka's answer. For her, an option is something you can choose and a commitment is something you promise to do. When I understand it, commitment is to the goal and option is how to reach the goal. That's exactly correct. And if you just look at the pictures, the goal was up there and options are all the multiple ways how you can get this. This is why we took that picture. Dad, what if you have too many options? Right, so some time ago I did a DJ set with your brother and what a lot of DJs have is all these knobs and all these different options and typically what people like to do is use all these options. We want to lose all these things. And we have an interesting story from Prince about that. When Prince created Wend of Skry, he made it, but he was not happy with it. He was editing, he was adding something by the song. Okay, so he had a hard time because he played all the instruments and he wants to keep adding stuff to it, but he wasn't happy. And he realized at some point that adding something was not helping him and he made the song better by removing the bass line, which is something that was never done before in the industry. And for him that made that song perfect, removing something instead of adding something. A lot of people have a hard time doing that because of... FOMO, what means fear of missing out. Yeah, so a lot of people have problems doing that. And so we're going to ask you this question. For who is it easy to say no? Let's do a show of hands. For who is it easy to say no? Not that many people, which is typically what we expect. We have about the same thing in Europe. Some people say it's harder in India, it's not true. In Europe they have the same problem. And Woody had an interesting quote about that that actually came from Peter Sange, Oana mentioned Peter Sange yesterday as well, is that 90% of the time what passes for commitment is really compliance. People having a hard time saying no and we think that they say yes. We think that they're committed, but actually they're just compliant with this. And this is making a hard time because if you're not able to say no, sorry to say, but your yes means nothing. Because you keep saying yes, and if you say yes all the time to me, I don't know if you will do it or not do it. And that's a very hard time. So to help you with that, what we're going to do might feel strange, but we're going to ask you and help you say no. Let's try this, together with Keke. Three, two, one, no. That can harder. Okay, maybe stand up. Let's try standing up because you'll have much more energy trying to do this. Okay, do my... Three, two, one, no. Ah, a lot better, a lot better. Thank you. Okay. Dad, you give them all theory. And theory, I found that boring. Let's give them an example. Right, so let's talk about something that is much less boring. And let's talk about school, right? Okay, so imagine on Monday you need to go back to school. What are the options for you to go back to school? I can go back to school. I can go with bicycle. I can go with bus. We have the great thing that we have a bus station right in front of our house so that actually the opportunity goes to go by bus. Go with car. This is a car created by Scrum that people don't know. This is created in a workshop at Agile DC 2013. So using Scrum for creating a car in one week. Unfortunately, this also brings us to a more negative advertisement. Is that one of the people who's on the picture, Manoj is at this moment in need of a spare kidney. So we're looking in the community if somebody has a type O blood who wants to have a spare kidney to help them out. It's a long shop, but we're going to try it out. Okay, let's go back to the presentation. We said we were going to explain some of these things. So we know that options have value. Now, creating what is value on Thursday, no, on Friday, I think, Arrel has a session about value. There was a session this morning, I think, about value as well, because how do you define value? It's really, really hard. Some people say, no, it's easy. I can tell you what value is. We know from no estimates that it's already hard or for a lot of people it's hard to estimate just how the stories are, but the value part is even harder. If you think it's easy, just think about what's the value of kissing or getting kissed. It's really hard. Could you say, could you put the amount of money in it or something else? It's really hard to value. Still, the goal is, the idea is now to ask, okay, what's the value of the different options? What is the value of going by feet? When the weather is nice, it's nice to go by feet. Okay, so what's the value of going by bike? I can go alone, but I can go also with my friends, and it's pretty fast. Okay, so what's the value of going with the bus? When the weather, when it's raining, I can go with the bus and I'm dry when I drive. Okay, what's the value of going by car? It's really fast and I can take a lot of stuff with me. Yeah, so this brings all the value so that should really give us an idea on how to give you all the information to decide on how to go on Monday. Right? How would you want to go on Monday? Dad, you said never commit too early. Right, that was one of the things in the mantra, we should not forget.  It can be raining, I can have a huge jet lag and all that stuff. Yeah, so there's too much information that we don't know yet. So you need much more information. So what can you do? Dad went inside. So that is the thing. So we need to look there for when does an option expire. So let's look there. When is the option to go by feet expire? 620. Yeah, so the goal is to arrive at school at around 8 so that means she has to leave one hour 40 minutes earlier, so that's 622 to leave. When is it expiring to go by bicycle? 735. That's a different timing to get there. When is the bus leaving? 730. Yeah, so the bus is right in front of us so let's say leave the house at about 7, something like that. And then by car, when is the expiration there? 740. Yeah, it takes about 10 to 18 minutes depending on how you look at it. There is of course with a car another expiration if you both have to work early, we might have left already and then that's expired but let's just look at the normal situations there. So let's look at, we put everything on a timeline the expiration timeline. So if you just look at it, you can see it's 640 feet 703, let's say 7 bus, the bike we see, we see the car at 740 and then school starts at 8. Now you also see like you said you see 740 it was set somewhere between 10 and 18 minutes. Some people say oh but then it should be 750 because that's the real expiration. These are the people who always come late because they take the minimum time. We try to take it a little bit longer than there is some extra option and maybe she's a little bit early but that's about it. Okay. Dad, it's not the expiration timeline but the decision timeline. Yeah, so it's not really about the expiration it's about taking the decision. Imagine that it's 710 what are the options that you can still decide on? I can go with bike and I can go with car. This is why it's so important to think about the expiration timeline and to put everything in a moment because then it helps you to think about these things. It really helps to make these decisions. But what we really want to do is also how to avoid to commit too early. Let's look at ways how to commit too early. One, post bone commitment. This is a very old picture of me and my partner in the very first year we were together. We didn't want to get married because we thought it was way too early to be committed that much and say into the marriage because we didn't know each other well enough. Still we were thinking like hey we like each other and we think it's serious so we took some fake wedding pictures that we send off the family and friends as a kind of in between. Two. Two, collect information. While we were in the relationship we have the time to collect information to know each other. To get to know when things are going bad what is this person doing? Is he stopping in the middle of a problem or is he continuing? Is he fighting with me and how are people fighting? Because that's really important information about relationship. How do we deal with each other in times of troubles? That is what we do with collect information to learn from each other. Three. Two is options. Easiest to change. So instead of buying a house or getting married we decided let's go on a holiday together because that's a very easy option to change. If it doesn't work out after the holiday we can just say we separate it again and there's not much fuss to do except for the emotional part of course but the rest of it is much easier to deal with. Another way is then I was already living on my own so you could buy a house and not buying a house or doing all that paper stuff. So these are two things that are options that are very easy to change in software we typically put a layer in between that helps us to decide what database connection for example. Things like that. Four. Invest in an approach that allows change to be easier. Right. So this is not about the relationship this is. I was really interested in having a walking desk at home and I was planning to build a house, a new house where I wanted to have that walking desk in the ground so that you didn't trip over it. And then I realized at some point that was really a big design up front because I was thinking redesigning my home office how to do that and I never ever had a walking desk I had even no idea if I actually would like to do that. I just had the idea I read it somewhere I saw some videos and I thought it was cool but I never done it. The day I realized that I came home and I told my partner like look I'm going to buy that I'm going to invest into a treadmill into a desk that can go up and down to see if I actually like it. Turns out I do. So six million steps later that's exactly what I have in my new home office which is a very big investment but it's at the moment that I already know that it's working for me. So that and before I invested just a lot less money to see if it was worth. Staff liquidity. There was already a few people this morning talked about moving people and stuff like that so staff liquidity is a really important part of real options. Now, sorry. Who is an expert? Let's do a show of hands. Who thinks he's an expert in what he or she is doing? Not that many people dare to say I probably think you're way too modest but okay that's possible. Now conventional wisdom says experts they get expert jobs and they need to do the expert job right? This is something you probably see a lot experts are really doing that job. Problem with that is that these experts are very quickly stuck in that because these are the people that only do this. And very quickly in a team you have a team of all experts. This is the database expert. This is the UX person. This is the test person. This is that. We have all these experts and that is really a problem. People are stuck. Doug Norton he's already left today but he talked about this this morning as well. That it's really a hard part. People are stuck there and they cannot move. What staff liquidity says is that let's give the juniors the expert jobs and let's give the experts the time to help all these people. And let's help them because if we have juniors people who are less good at a certain job and we put them in these positions these experts have the time to help them out. And if it's really really hard the hardest part of it they'll jump in and they'll add and maybe do it. But for the easiest thing of the expert job these juniors can do it pretty well which is nice for the experts because it's less boring for them because the easiest things of the expert thing is really boring for these experts and it's nice for the juniors because they improve. Now if you want to do that what Chris said is that sorry before and what the result is of course that these people are moving much more quickly does the term staff liquidity more liquid. If you want to do that what Chris said is you need to have a scoring. You need to ask the people themselves to score themselves and this is his list so zero means I can I know nothing one means I can run it two means I can tweak it or box fix it three means I can redesign or re-factor it I own it. This is of course a typical software thing we translated that to this presentation so we said okay let's score ourselves for how we do. I'm doing this for for for a living lots of presentations so I score myself a tree an expert on this. Cheke she started doing her very first presentation and three and a half so for already eight years she's doing some presentations so she still scores herself a two she's not at my level but she still scores herself a two.  Real options. I've been talking about it for about ten years so I consider myself an expert. Like we say we so show you some examples how we do these things at home so Cheke learned a lot about that and we explained even more about the theory that's behind so she scored herself a one. English. My dad is not a native native speaker I give them a two he's really good in English as well. I have never had English at school but I can talk with you you can talk with me I give myself a one. She learned everything from YouTube very educational. Staff liquidity it means there was a question this morning in Doc's session about productivity and for me staff liquidity it actually increases productivity. Now we took this picture it's hard for me to show it from here but if you look at races like this if this is a time race with a group what they're doing if you look at it on television is they're cycling all the time and it's not the best one who's the first. No they're constantly changing the first person that's exactly what staff liquidity wants you to do. It really wants you to change very quickly and people even the worst driver they're still good but if you're in IT probably a lot of you are already good even if you don't call yourself an expert. If you just change a lot you will learn and you will actually help the team. Staff liquidity reduces risk. Yeah I told you that I would show you a picture from Adnan Ahmed that he puts on his blog about truck factor or bus factor. Who is familiar with the term bus factor or just a few people? The negative version and the positive version the negative version is you get under a truck and then you're dead and then your team is in trouble because they lost the one expert who knows about a certain thing.  But this is if you're the only person who knows something your team has a bus factor or truck factor of one. If you have multiple people it's much easier to go on holiday and even to die because your team can continue to do it. It's not lies for you but I actually had this on a team that a person ran into a tree on top of all the personal issues that you have we actually had to ask our customer for the last executable so that we can decompile so that we can have the code because he took his computer with him. Shit happens. Staff liquidity also increases trust at multiple levels. Just this is my son with me on stage age 13 just putting them there giving trust also increases trust and helps in multiple directions and I can see that in also we're just having juniors helping out and doing it you need an initial trust to put them there and to give them the stage and to let them do these things but it increases trust in all directions. If you want to this is a new slide here that I just added because of the talk I said with talk if you want to experience some staff liquidity we have a workshop on Friday on pair programming where we actually let people experience how it is to quickly rotate in a team. You need a computer people will actually work and develop software together but you'll do that very quickly and you will see first-hand or you'll experience first-hand how that goes. Yeah, thank you. agile brings more options This is maybe not the best picture to take that but imagine that this is 50 meters and people had to jump 50 meters or 100 meters you would think it's insane and there's not much chance that you might survive. This is what they did at the waterfalls, Niagara waterfalls and stuff like that it's very dangerous. If people could jump just 50 times one meter it's much safer. That's what we do with agility. We have every time one option. Naresh just talked about the project that he had 700, what was it? 700 experiments that failed. This is 700 small times. That's a lot less worse than failing just one time for the whole thing that we deliver that brings much more options Technical depth is a sold option When I heard this tweet or I heard Steve Freeman said that I wasn't sure I understood it because for me I thought technical depth isn't just an expired option but he replied to me it's not expired because still people can call on it it's technical depth that the code is no longer there the option is still there it slows you down and all these things are expired as it's completely gone you can still do something with that Dimensional planning I told you this is an example on how you can do and practice some of these real options we'll talk about how you can go in software the example is not from software we'll talk later about that so first the way of going somewhere is the dirt road The dirt road is not very handy but you can go from A to B and typically it's not going to with the sports car it's not scalable probably better to do on feet and on horses and stuff like that but you can still get from A to B The cobblestone road is a little bit better you can go from A to B also it's a nice way but you don't have many lights or shops and you have crossroads so it might still slow you down the fastest way to go from A to B is of course the highway you have lights you have four lanes each side you have all these different kind of options you have exits you have all these different kind of ways to get there so let's take a real life example and we thank Naresh for that so imagine the old way to go from Erungabad to Fatihabad in the old way what we would build is just a highway now imagine that this is done and you come back and the client comes back and it turns out there is another Fatihabad we built a highway from Erungabad to Fatihabad to Hryena and there is also a Fatihabad in Madhya Pradesh damn we built a wrong highway so the project manager comes back and he says damn it who's gonna pay for this expensive mistake now remember this is the old way of thinking what's the old way of thinking to do to deal with that is create a tighter contract so the customer has to pay for it right that's a very interesting thing to do because it turns out can you read these words? no, not very good so let's enhance this a little bit this is the very small boat what does it say? original contract the large boat, what does it say? change order this is how these contracts were made we sell to governments to large things and we have to sell them we only get the contract if we sell it very cheap this is how you get contracts we sell them very cheap and then we make sure there are some parts in the contract that say if you're a mistake or are not clear about what city to go to or if you make another mistake you'll pay and you'll play a huge premium so you pay for it that kind of works if you're that project manager but it typically works one time because afterwards they say we're not going to pay for another boat or whatever so we prefer to work in a more way which is in the dimensional planning so we first start with a dirt road from Arungabad to Fatihabad, Haryana right, so we said the customer comes back and says it's the wrong Fatihabad ok, so we built another dirt road from Arungabad to Fatihabad, Madina and so the customer comes back and he says it's again the wrong Fatihabad turns out there is a third one I have no idea I don't know India that well so what do we do? we build another dirt road from Arungabad to Fatihabad Uttar Pradesh so what does our customer say? he's happy and what does his customer say immediately after he says hooray now I want a better road because of course you built a smaller feature right, so what do we do? we build the cobblestone road we build the better version of it ok, so now there's two ways that the customer can react the typical reaction is now I want a highway so we built a highway but there is in that case also another thing that happens very frequently this is enough, we don't need the highway what we've experienced is that we have not just a smaller version but a little bit more enhanced version turns out that this company realizes hey, we're not twitter, we're not facebook we don't have millions of users connected all the time we're, let's be dangerous and what I'm saying, we're just a bank and we only have 100,000 users a month, maybe 1,000 or 10,000 connected at the same time but that's different than 1,000,000 users we thought because we're a bank we need a very scalable version turns out that this cobblestone road is good enough to sell and work for all our customers we don't need much more that happens a lot ok, so that's ways of looking at that an interesting part to look at that is of course, let's look at the cost the cost of the old way the old way, we paid for the wrong highway we paid sometimes from again the wrong highway and we paid for the correct highway so we said this is a question mark, why because once we're into that wonderful way of thinking once we did it, deliver something wrong we'll look very careful and make sure that we don't make that mistake again we think we don't do it, we'll see later on if that's true or not but we're not sure if we would pay twice for the wrong highway let's look at the dimensional planning costs we paid for the wrong dirt road in Haryana, the wrong dirt road in Medea, the correct dirt road in Uttar Pradesh the correct cobblestone road in Uttar Pradesh and sometimes the correct highway in Uttar Pradesh yeah, depending if we need it or not if you just count the numbers, if you're in finance and you just count 1, 2, 3 it looks like the dimensional planning is way more expensive but I think you agree that creating a wrong highway is way more expensive than creating some extra dirt roads that's the same thing for features but if you just look at counting the numbers it might look like you delivered more and it's more expensive but that's not the reality but that's just one side that's the costs, let's look at the value without dimensional planning it will take a huge amount of time to deliver that highway because first the wrong highway then the better highway it takes a very long time to deliver that one with dimensional planning we very quickly have some return of investment don't forget a dirt road still works we don't have the scalable version we don't have everything but it could still work I've delivered software where people would still put in everything manually we had what we called an army of students monkeys sometimes called that was very expensive but we were live with a feature like two years before our competitors and we were selling stuff people were sending us faxes and stuff like that to buy stuff from us that they couldn't find online but we were selling already we were getting money it was costing us money but in the market they looked wow we're ready so it was giving us a return of investment we said we'll talk about later because there is also a second we built all the ways in Maharashtra but there is also one in Bihar so I said they would look very careful if they have the right but they might forget that they need to check the starting so that is what is with features if you look very carefully let's now not make a mistake in that direction and forget the other part this is why it's still expensive okay that's a very nice story about highways and stuff like that how did we implement that and what we want to talk I'll give you an example of real options way of building a house so we had 100 years old house so did we like the house we loved the house many features are broken so this is a very nice house except electricity was a problem water was a problem, heating was a problem actually it broke down before we had a solution there so it started to become expensive and it was kind of impossible or very expensive to change it we were looking for 15 years of redesigning the house to make it better for our family turns out that our IDs grew faster we had money on our bank account so that didn't help but it also had another feature the old house has a huge garden which is nice but that gave us another option also it gave us the option to build a house in the garden as you finally look you can see the old house so we built the an extra house in the garden while still living in the old house you can think oh that's already a smart part but this is just the beginning of the story we were, while we were building the new house like I said the heating completely broke down now this was October, November it was already snowing and we didn't have any heating anymore I still remember on a holiday that she was eating with a jacket on and with so we needed to move to the new house as fast as possible what we're going to show you is we're going to show you a list of features that might be needed or might not be needed what I would like you to do is take one minute and think for yourself what are options that you think you would need before you would move to a new house so this is the list of features so think for one minute about what are the features that you need we'll just ask questions in a minute okay who wants to shout out something that he or she needs electricity take it, write up electricity wait, wait time to write it down okay the roof I heard the roof so let's write out the roof water water toilet I heard solar panels some people say solar panels did you already hear something you disagree with solar panels some people say we don't need solar panels so let's prep it out in red solar panels we don't need okay shower, we have people who would like to take a shower funny enough let's not go too gender but it's the women who wants to shower and it's the man that I'm hearing that says no we don't need that let's not go too much into that discussion kitchen kitchen so let's show us our list we did have a roof, we did have a toilet we did have baths, electricity, water we didn't have a kitchen how did we deal without the kitchen we we have the old house and we're cooking there and we go with feeds to the other house and eat in the water we had a house in the garden it was only 50 meters so we cooked in the old house because we preferred living in a warm heated house without a kitchen and then only later and cook in the cold house and then come back and eat in the warm house that gave us the extra option because we did it that way of course that's not scalable, that's not for a long time we only took one month before the kitchen was installed just before Christmas, right on time but we lived for one month in a house without a kitchen internet connectivity now I have three kids, teenagers insane not having internet right? but it was impossible to get internet connection at the new house but we still had the old house so I took a very large utp cable from one house to the other drilled some holes in the old house put it into the new house through a window that was kind of cold but the kids preferred it a little bit cold from time to time when we can watch when we can use the internet Keke, television, how did we do that? we watched at Amazon Prime and we watched YouTube thank you internet we could watch television shows on the internet so we didn't need television although we missed some cable things so we had to take a shower that's an interesting thing I still had a shower in the old house so what I did up in the morning is I get up in a warm house, get dressed go into the freezing cold in a snowy thing to a freezing cold house it's even more freezing now because nobody's living we don't have any electricity heaters take a hot shower because that was still working then get dressed again and go back to the hot house to the maximum I'm the one who took most showers I'm not sure if my 16 year old son took a lot of showers because he didn't like to do that but ok, it's ok he was playing basketball and took showers there after every practice and stuff like that but it's doable, again not scalable not something you want for a very long period for two months that was possible I preferred it would have been in the summer but then we made it not even needed to move I have a large training room that I can use upstairs but at this moment in probably even the next year I'm not even thinking about going there so who cares that we don't have stairs to go up to the training room it took six months to deliver that stairs and that's fine, we didn't need it that's ok, the stairs are there I'm still not using the training room because I don't have time for that for getting everything else solar panels, we didn't have solar panels they were actually bought they were already sitting in whatever the storage place of the person who needed to install but he didn't do that which is too bad because we used a lot of electricity that could have been free electricity because we already paid for the solar panels I didn't like it, but at that time I had different problems to solve to make sure that we had other things there we still don't have a garage so the cars are still outside the bedroom floors are really not really installed so the nice floors that we want but it's doable to walk on it we have papers on the floors to make sure that we don't damage stuff that means if we don't have the floors we cannot put internal doors because they have to be put on top of the floors so that means right now we have curtains in front of the bedrooms not ideal with some teenagers but it's doable it's not something we want for a very long time it's something that's very high on our list to do but we don't have a bot yet we actually, thanks to a friend on the internet bought a plastic bot like you have a swimming pool but now a very narrow one for a bot so if we finally can take a bot we'll probably take a nicer one here in the hotel but these are options, these are things that are actually possible to do that the garden, well we do have it but there is a house there there's a little hill with lots of other dirt in there so we cannot use it we don't like it because of course we bought the original house with a very nice and large garden but at this point this house is like 100 times better than the old house just showing you that thinking in a different way helps and creates extra options at places that you would not even think about so a lot of people when I ask this question when I ask this list and this is just a limited list if I would give you 10 minutes to think about it a lot of people would come up with a lot more things to think they need but in reality if whatever happens you don't need and this is really important getting into a mindset of what are the options that I need discuss what is it that I need about it the water we needed just for the toilets so we needed water that was not an option to not have it and going to the toilet to a freezing cold house that was not an option for us either until that is installed before we actually move so this gives different things what we would like you to do now there's not that many people who knew XP this is not the picture that Ken back made but this is based on his picture of the three loops he said in XP there's multiple loops what I would like you to do for one minute is think about all these different things that exist inside extreme programming if you think you don't know some of these words there I would like you to think what is it that you need for these things we're not going to have a discussion because we're running out of time but the idea is let's take 30 seconds to think for yourself and to take that as a kind of homework to think hey that extreme programming how does it give us options why is it that it took off because we had these options you can discuss this with us later on we're still here till Friday at the conference so there's only the rest is wanting to do and let's talk about what did we talk about we talked about real options mantra, staff liquidity and dimensional planning well there's actually one other thing let's thank you did you know who that can say? no okay let's just thank you very much for having me I actually wrote a few books who wrote one book I wrote a few books and if you're we're in need of a few people who want to help out we're creating or a few years ago we created something that's called who is agile in India if you think people who should be in the book contact me on Twitter or somewhere else because or if you know Sanush and Tushar they are the people who are actually doing the writing and helping out it's a very specific format so if you have an idea for something that should be in there you can contact me as well thank you very much
