What are the 4 principles of agile?
Continuous Integration.
Agile Methodology. Rapid Release. Incremental Delivery. Real world projects are not black box. Continuous integration is simply the practice of integrating the software code at each stage. It has four benefits which I will go through below.
Let's start with the easy ones. Continuous Integration increases programmer productivity because they know when a change was added and committed to the repository. This increases the speed of the code which in turn helps it to be reviewed more efficiently. It also removes the risk of adding a bug.
Continuous integration increases business agility by allowing businesses to release software much faster. Businesses can then react more quickly to changes in the market or new competition. The key here is "much faster".
Businesses can release software that is more competitive by releasing it sooner. They don't have to wait for their development team to complete the full product. They can release a limited amount of software, such as a beta. It is always important for software companies to focus on building customer value. Beta customers will always give you more confidence in the future release.
Continuous Integration allows you to understand your customers and how they want to interact with the software. You can easily see where your customers are going to be, where they might need support, where they are having issues. In addition, you can make changes based on the feedback you receive.
What about continuous integration? The key to continuous integration is that developers should merge their work every time they commit their changes. It sounds simple, but there are still a lot of projects which don't follow this principle. They might follow a single branch strategy, which means a developer creates one branch from the main trunk of code.
This works well for smaller projects, but as a company grows this quickly becomes a headache. There are a few different ways in which projects don't follow a single branch strategy.
Many projects don't use branches for all the areas. For example, there may be one branch for development and another for production. There will be a branch for testing as well.
Developers may create a branch for their feature, and then merge it back into the main branch once they are done. If you are working on a large project, you may create a branch for a release and then another for maintenance and bug fixes.
What are the 5 stages of Agile methodology?
What is Agile methodology and what are the 5 phases that the Agile methodology goes through?
What are its benefits? The Agile methodology is a method of software development in which software requirements are continuously evaluated based on customer demand. The method is characterized by several stages, namely: User stories. These describe features or functions that the user needs and that the user needs to be able to do within the scope of work. Each story is described using a user interface such as a story card.
These describe features or functions that the user needs and that the user needs to be able to do within the scope of work. Backlog. This is a collection of user stories grouped into epics. Each epics can have more than one user story.
This is a collection of user stories grouped into epics. Working software. The first version of the product is built using existing functionalities and features. It is a collection of user stories with functionalities and features defined from the backlog. The first stage is the most difficult and slowest. However, it leads to an evolutionary approach.
The first version of the product is built using existing functionalities and features. Incrementalism. The final product must be usable. Thus, changes and modifications to improve the initial functionality are made. Each change will be reflected in a next iteration of the product and will then be implemented. The methodology is based on incremental feedback from the users.
The final product must be usable. Evolutionary delivery. When the process is completed, the user stories with added features are integrated and then the final product is delivered.
The 5 stages of Agile methodology. Each of the stages is associated with Agile characteristics. According to Wikipedia, Agile methodology is a process improvement method that incorporates short development cycles of two weeks and focuses on delivering working software over the course of iteration (an iteration is usually at least 4 weeks long).
What is agile vs scrum?
An open question.
I'm learning about scrum in preparation for giving a talk at my company's internal development conference. (And I can't wait to be there, so this is an important topic for me.) It's been helpful to put together a collection of the questions I had, and the links I found, to address them.
Here's what I've learned so far. Definition. First, it's not necessarily a specific thing, like "development methodology". The term was invented by Michael Hammer, as part of his PhD thesis. What is "agile" (without "development" or "development methodology") is also a question. But the fact that it's answerable question is probably the biggest selling point. If you're interested in improving your development processes, it's useful to know what it is.
But it's also good to know what it isn't. That's why I think most places that define it as a "development methodology" are confusing it with scrum.
Agile Definition. A few people have written their own definitions. One from Mike Cohn gives the following: Agile software development is based on the idea that software development should be an evolutionary process that responds to changing customer and market requirements. As requirements change, the process evolves. It usually starts with a minimal spec which is then incrementally refined over time to keep pace with the market and customer requirements. We call this agile.
You can also find definitions by reading through some of the answers to my other questions. Scrum Definition. I was looking through the Scrum Guide when I ran into something that makes sense in hindsight: The Scrum framework is comprised of a set of practices, not a set of tools. While Scrum is a framework for conducting an all-embracing form of project management, Scrum is not a project management system. Scrum is not a project management tool.
One of the reasons I find this important is because there is a danger of reading one definition and thinking you understand what it is. For example, the Scrum Guide talks about the Scrum framework and also lists the Scrum framework tools. They both say "Scrum is a framework", but they mean slightly different things by "framework".
