### Keynote de clôture &quot;Path to Agility&quot; avec Ken Schwaber

health of the people in the room will depend on it here are some variables that we may want to consider and you may want to compare those that you thought of and see if they fit in so certainly the number of people in the room metabolism of the people in the rooms that is are they key generators or heat sinks the activities of each person in the room at every point in time during the day are they doing exercises are they sitting there bored what are they doing are people opening and closing the doors as they’re opening and closing the doors are the open for very long and what is the temperature of the hallway outside that is letting in there what is the weather including Sun Cloud’s outside temperature and of course you’d have to know this at every point like maybe every minute or two during the day the temperature of the adjoining rooms the things that are going on in the adjoining rooms the construction material of the building the floor of the room will serve food be served when what type how much how hot will it be so all of these and perhaps even other variables you would have to figure into an equation that you would program it to the computer you should know calculus to do this because you’d be generating a multivariate a nonlinear equation in which every variable would be dependent upon every other variable so I hope the people you chose are very very good programmers not many places were successful with this the programming the variables were too many and number of people died PS died from heatstroke or froze to death and that led to the invention of something you’re very familiar with the thermostat so thermostats were created for situate that are complex so if i asked you to control the heat in the room and it was a simple situation that is the lower left-hand corner that is the building construction the weather patterns the people in the room all that was very very well known then we could have programmed the computer if it were complicated where we will block but there were some things that we didn’t know still we might help the people survive but if it’s complex we’re in this circumstance more is unknown than is known which is our situation with controlling the temperature in the room then we run into a situation where it’s very hard to come up with a program that’s going to work if it take Chaotix it’s yours forever very little or nothing is known then we actually don’t see how much of a chance so this type of complexity that we were dealing with in trying to control the temperature led to the thermostat which is good for controlling complex and sometimes even chaotic circumstances and this the thermostat is actually what we call an empirical process driven device that is it does not care what the variables are it totally ignores the variables the actual temperature in the room at any point instead drives the setting drives the thermostat to put on air conditioning heating and maybe even move blinds if it could so these are what it does instead is goes out periodically and checks the temperature in the room compares it to the 22 degrees centigrade that we set as its goal and based on the differential it will initiate heating air conditioning or slight movement now it’s probably important that we have the thermostat inspect the ambient or the current temperature in the room frequently so that it can put on heating and air conditioning so they can keep the temperature somewhat stable if it only checks them every two hours the amount of temperature shall may be too great for to overcome so we certainly wanted to do frequent inspection of the temperature and adaptation by turning the air conditioning and heating systems on this is called Justin time planning and it’s based on actuals so we don’t care about the weather forecast we don’t care about the prediction of how many people will be in the room all we actually care about are the real temperature in that room at any point in time there is so we did lay down one criteria which is it has to inspect the temperature frequently enough to keep it within the range the other requirement is that this

anymore a scrum but is the equivalent of the tape over her mouth rather than listening to what scrum saying you have changed scrum so you don’t hear it anymore so for instance the daily scrum it is a just-in-time planning me and it’s intended to reduce technical debt that is when people do things that don’t don’t work together with what other people are doing the effort to undo them is much greater than if you would simply done them right up front and so we meet every day and look at where we are during the Sprint so that we can readjust our work that we’re going to do for the next day to optimize the chances of us delivering what we’ve said very very valuable point for optimizing productivity and value you eliminated and you immediately start incurring technical debt so this is a scrum adoption profile the really good news is that as a 2008 more organizations are using agile and waterfall and the bulk of those that are using agile are using scrum however what we thought what we in fact have found this is Jeff subtle and myself is there of those using scrum on most of them are in the scrum Buffy’s that is they have found many things culturally and organizationally and technically that make it so they can’t do it er ative incremental high-value just in time planning with a solid increment at the end of every sprint and so they either have subsided into an organization which is only partially there and won’t ever go further or they have taken all those things that they can’t do and this is an action plan for them to continual improving until they really are an agile organization so that’s the right-hand the tailing edge of these of the distribution is those are those that are really using scrum now that is a really good thing that we’ve gotten so many organizations that far or even into improving however what Jeff and I have noticed is that many of these people organizations that have achieved excellence when the person who is leading that effort the vice president of engineering the CEO someone like that when they leave the organization the organization slips back bit by bit doing things that it used to and the excellence is laws they’re still better than they were but that leadership that helps them and gives them the direction to be epsilon is gone and the existing culture ways in which people are scented way in which people are promoted way in which people work together goes away as the way it used to happen reasserts itself little discouraging but you know Jeff and I will get over it America we have ideas about what we could do about it some of the things that scrum does on the current culture that caused this to happen is when you’re using scrum empirical replaces predicted this means that the art of the possible doing the best you can replaces just wanting something and hoping that if you say you want it loudly enough it will happen and when someone who is used to empirical management leaves and you hire a new predictive manager everything slides back we also have the idea that transparency is value neutral that is very much like the Abraham Lincoln quote we want to see where we are so we can make decisions about what to do so we do want to see waste we do want to see impediments we want do you want to see when we don’t do what we said we would so we can make the best decision possible now if you have someone that they’ll use that you will do well if you have a new directors top manager come in who has always survived because he or she’s good at politics that transparency is horrible because it disables politics politics only survives when things aren’t clear authority moves down the organization scrum teams are self organizing and self-management and accountability is very specific if you have someone come into the organization after he excellent and they believe that the only way that things will work is if they tell people what to do because they’re so smart scrum will suffer agility will suffer and also I’m scrum and LD require more work you have to pay attention to what’s going on look at things that you may not want to see and
