By definition, the word ‘agile’ means the ability to move easily and quickly. In product development, it translates to the ability to create change and quickly respond to issues and adapt even when inside a turbulent and uncertain environment.
The Agile Method is a project management approach that is used in software development. This method helps teams in adapting to unpredictable events during the construction of an application. Agile Method uses iterative and incremental task sequences which are referred to as sprints.
A sprint is a particular amount of time that is allocated for a project phase. Once this time period has expired, the sprint is deemed as complete.
There may be arguments raised amongst the team members on the quality of the development but no more work will be allocated on that specific project phase. The rest of the project phases will be developed within their allotted time frames.
The Agile Method abides by the following general principles:
Scrum is an agile application development approach that is employed by many software companies. It’s a collection of rituals, team roles, and values that are combined together to come up with iterative work output. Although Scrum was first used in the software development industry, it has also been found useful in school, military, manufacturing, and other institutions and industries.
Most might mistake Scrum as an acronym but it’s not. The term ‘scrum’ was introduced by Ikujiro Nonaka and Hirotaka Takeuchi in a 1986 article in Harvard Business Review. They described Scrum as a ‘rugby-style’ approach to developing a product. In the sport, teams move forward while members pass the ball back and forth. In 1995, software developers Jeff Sutherland and Ken Schwabber presented their own process of the methodology which later became the currently used Scrum Framework.
Scrum and Agile are commonly mistaken to be the same methodology, but the truth is, they aren’t interchangeable. Basically, the Agile Methodology is the umbrella term. The Scrum Framework is just a subcategory. Scrum is based on the Agile Methodology but not all agile development can be considered Scrum.
Scrum is defined by the following principles:
How Scrum Works
The Scrum Framework is composed of three categories which are broken down below:
Scrum Roles. There are three core roles in the Scrum Framework.
Scrum Events. There are five events that define the Scrum Framework.
Scrum Artifacts. These are physical records that contain the project details.
Product Backlog is an ordered list of all project requirements which is used as a single reference for all imperative product changes. The Product Backlog is overseen by the Product Owner which includes how it’s provided to the team and how the contents are ordered.
Sprint Backlog is a list of the tasks specified in the Product Backlog that team members will work on during a particular Sprint. Items are prioritized until they’re ready for the Sprint.
Product Increment is the entirety of the tasks completed during a particular Sprint as well as the other previous Sprints.
The Agile Methodology has given birth to product development approaches that are focused on simplifying the whole process. One of these is the Scaled Agile Framework or SAFe. SAFe, like Scrum, is another Agile Framework for applications development.
SAFe provides a lightweight and simpler experience for the applications development team. It is based on both Agile and Lean principles and is used in implementing systems and software at an enterprise level. SAFe is designed to satisfy the requirements of the stakeholders in an organization.
Although it’s lighter in weight and simpler in implementation, SAFe can expand to handle complex system development and large value streams.
Agile, Scrum, or SAFe?
Agile is the umbrella methodology where Scrum and SAFe were derived. Scrum and Agile work for teams while SAFe is for enterprises. Another big advantage of SAFe is that it’s constantly evolving.
