 Just a very short introduction about myself, my name is Ebin John. I work as an agile coach with Society General Global Solutions Center. As an agile coach, I had worked with companies like Nokia Siemens Networks, GE, Alcatel Lucent, Valtek, etc. So I am interested in NLP, Neuro-Linguistic Programming and little bit of behavioral and psychological aspects of human beings. So one of the Harvard review which actually inspired me to create this particular deck, this is the first time I am delivering this topic in half an hour. So I have to maximize your value add, I have removed couple of things, some exercises, etc. So let us bear with me and let us see how can we create more value add, yep. To help you to use your low of 2 feet, I will first straight away tell you what is the objective. The one of the objective is to establish the or throw some light into this relation between size and productivity and the second one is about some factors affecting the team dynamics and with that context how these things are getting affected in some of the ceremonies what we do as part of our scrum or agile principles, yep. So how many of you have designed teams, how lot of managers around here? So normally when we think about designing a team, what are things we normally think about? We want to have everything optimum, optimum productivity, optimum motivation, transparency, collaboration, lot of things, right? We work, we do lot of homework when before we create a team. It is not that every Tom, Dick and Harry can come into a group and then we call it a team, right? But today we are focusing more on size, how the size impact on productivity. So if you look around in the different places in our day to day lives, we see in sports different games of different team sizes. You have baseball nine people, basketball five, cricket 11. Many times you would have taken this for granted. We are not questioning why there is different team sizes. So but it is almost certain that the team size have significant impact on performance. So there are lot of people did lot of studies.
