Speaker 1 Today we're going to talk about the variety of approaches to the  software development process. As you may know, the project development  starts with choosing an appropriate software development methodology. So how do you decide which ones, which your project needs best? This is actually why  we're all here. In today's topic, we are going to discuss five different  developmental philosophies and how to choose the best one, especially for you. First of all, let's clear out what software methodology means. You can call it  software development methodology or software development process, but it will  always mean the same thing, splitting software and building work into different  stages with certain activities for the purpose of more effective planning and  management. So what are the stages? Well, their requirements, design,  implementation, testing, debugging, deployment and maintenance, usually all of  them are present in any time of methodology. But the stages can be mixed up in  many different ways, and this makes the difference. There are numerous  software development methodologies, such as waterfall, clean room, rapid  application development team, software protests, personal software, protest,  Scrum, Kanban, Xtreme programming and dozens of others. After years of  experience, we have formed our own opinion on the methodologist efficiency,  and have chosen five of them to use in our web and app development protests,  and today we want to tell you about them. Let's start with waterfall. The  waterfall, or traditional methodology, is a software development process flowing,  sadly, downwards through the stages of conception, initiation, analysis, design,  construction, testing, production and maintenance. Although one may call this  methodology obsolete, it's still widely used among developers. It's used pretty  good for a small application with clear cut instructions, which needs about 100  hours for its0 implementation. But if you suspect that you may have a lot of more changes in your product, this methodology becomes very clumsy. Scrum is the  complete opposite of waterfall. It's an agile, iterative development strategy which suits huge projects perfectly. The workflow is organized in a way that top priority  tasks are implemented. First all, the process is divided into iterations called  sprints, which usually lasts for two, four weeks. Thanks to such a workflow, you  can get a ready to use product or piece of functionality at the end of each  screen. Scrum allows changes to a product requirements even at the terminal  stages of development, which may save your time and money. It is perfect for  heavyweight projects with unclear requirements and constantly emerging  changes to a plan. Kanban is one more example of Agile methodology.  However, it differs a lot from scram. The main priority is given to milestones,  rather than velocity. The progress here is visual illustrating stage of work in  Kanban, the team is only focused on the work which is currently in progress.  After finishing one task, it picks up another from the top of the backlog, each  task is estimated according to how much time it takes, starting from its initiation  till the moment it's shipped. Using such a cycle metric, the team can plan and 

predict the product's delivery pretty clearly. Kanban is good for complex projects  with rapidly emerging changes to requirements. It can be really cost saving if  you have an experienced team for your project. The next approach we want to  tell you about is scrumban, as its name shows, Scrumban is a combination of  two previous philosophies. Some teams try to blend the ideas from these two for maximum efficiency, such as the fixed length iteration rules from Scrum and  cycle time, with the focus on the work in progress from Kanban. The main  advantages of this methodology is minimum planning and estimation of the team members and team work in general, which accelerates the development  process, little daily meetings that allow to find problems immediately,  retrospective practice, which allows to learn from your mistakes and  achievements. Scrumban is a little more expensive than clear Kanban, but it's  still cheaper than pure scrum because of its shorter iterations and faster product delivery. This mixed methodology is a good choice for complex projects, if  Saving money is not your main priority, the last one for today is XP, or extreme  programming as its name, hints. This methodology is used to develop high  quality software in a shake environment all these beneficial practices from  traditional software development are taken to an extreme level. Here twice more code reviews and more human resources to provide the peer coding are used to deliver an excellent quality product. You'll surely get a great product, but it may  take you longer because of more often reviews and cost you much more  because a bigger amount of specialists, quite XP is undeniably great for  complex solutions. Well, we hope that now all these terms are not just words for  you, and you got a clear picture on the topic.
