Mickey – Great question Minnie, Scrum is a framework that helps teams to implement Agile methodology Minnie – I have a question, I have also read about Scrum, what is it and is it related to Agile Minnie – Wow, all my doubts getting cleared now Mickey – Yes, we can say that in a way for every small module we have most of the stages of waterfall model implemented, and its done in a way that we get a workable/consumable module and any client feedback or valid and approved changes can be incorporated Minnie – Can I say that in Agile we implement waterfall model for each smaller module and not for the complete project This makes the process faster, flexible, and increases ability to incorporate changes Each of this small chunk becomes a small project that has its own requirements and a small workable and usable feature or module is developed at the end of each cycle.

Mickey – So in the Agile model of Software Development, we break the big project into multiple smaller chunks. We needed a more flexible, dynamic methodology and that gave birth to the Agile model of Software Development Mickey – So with the growing demands, time constraint, need for more flexibility and need for getting the app developed in small incremental process the waterfall model was not the best. Mickey – And suppose the customer gets new ideas 3 months down the line, there is not much scope of incorporating the changes in the waterfall model Customer/Users cannot give feedback unitl the complete app is ready Mickey – Yes, and in the waterfall model we do not have much scope of adding changes in middle of the process and not much options to see sections of the app getting developed and usable in frequent time intervals. Now lets say if the team says that it will take 9 months to deliver the app He will give all the requirements at once and the team will study and freeze the requirements and provide the time duration for development. Mickey – Also in the traditional model, suppose a customer needs to get an application developed. Mickey – Now lets suppose if in the middle of the project, say in testing phase, a customer requests for a change, we cannot accommodate it in the same cycle and will have to take this change in the next cycle of the project The team works on one stage, freezes it and then moves to other Mickey – So here we have step by step stages and we go in a flow. Mickey – Ok, Minnie, So do you remember the waterfall model of software development. Mickey – An agile team delivers work in small, but consumable increaments and not all at once like a bing-bang. Mickey – Agile is an approach to project management and software development that helps teams to deliver faster and efficiently Mickey – Let’s first look at the word Agile, it comes from Agility that means ability to move quickly and easily
(Mickey and Minnie found a silent space and sat there) Mickey – Ok, we have some time before your train arrives, Let’s go and find a place to sit Mickey – Ok, I know you understand better with story Minnie – I was reading all day about Agile, but could not actually get it Minnie – Hi Mickey, I have been looking for you One day Mickey was sitting at a train station when Minnie came running to him
