Summary: The saying goes, “Expect the best, plan for the worst, and prepare to be surprised.” The project development methodology is one such aspect that ensures the project outcome. It’s one significant decision out of many that you take during project development. However, it becomes complex when you have to select one out of many software development methodologies. So, we are here with a detailed comparison among the top three project development methodologies: Agile vs. Scrum vs. DevOps. Hope you find all your answers in this article.
Selecting the correct software development or project development methodologies matters the most. But, people always feel baffled when choosing one out of many. So, here we have come up with a guide to guide you on the Differences Between Agile, Scrum, and DevOps to ease your hassle when selecting the right one. But, rather than digging deeper in hastes, let’s just start with some stats relating to these Software development methodologies!
Did you Know?
- Around 71% of Organizations in the US choose to use Agile.
- Agile Projects has a 64% success rate, while projects under competing methodology Waterfall has only a 49%—success rate.
- Including Scrumban or a hybrid Scrum model, around 81% of Agile teams report using Scrum versions.
- From 40% of respondents in the first survey to 66% in the most recent survey— the use of Scrum has increased immensely.
- Around 83% of IT decision-makers reported implementing DevOps to increase business value.
- IDC (International Data Corporation) anticipated that the DevOps market is expected to reach $8 billion from $ 2.9 billion by 2022.
What Is Agile?
Agile is a software development methodology that involves constant iteration testing in the software development lifecycle. The method emphasizes incremental, iterative, and evolutionary development. An agile methodology breaks the process into pieces and integrates them for testing. There are many ways, for example, Scrum, Kanban, XP, and many others, through which it can be combined.
Dynamic processes such as project management and software development need the capability to adopt changes and new conditions. The waterfall methodology couldn’t meet the expected results of the fast-paced world of continuous technological innovation. Hence agile came into existence. Agile offers efficacious management of complex projects and improves communication and collaboration among customers and team members.
What Is Scrum?
Scrum is a methodology designed to build products in an environment susceptible to change. In Scrum, delivery cycles are known as sprints that generally last one to four weeks. Scrum teams are usually small, ranging between three to nine members, including a scrum master and a project owner. In Scrum, communication among team members and stakeholders constantly occurs to ensure that the feedback can be received and changes can be made accordingly and continuously.
Scrum is the most used methodology by around 66% of agile users. However, while the method is implemented by 66% of users, 15% of users use derivatives of Scrum, Scrum/XP, and Scrumban, as per an agile report released in 2021.
What Is DevOps?
DevOps is a software development methodology that focuses on communication, collaboration, and integration among IT professionals with an intent to enable rapid deployment of products. It’s a process that improves collaboration between both development and operations teams. This allows deploying code to production in an accelerated and automated way. In addition, the methodology assists in speeding up the process of developing and delivering applications faster. This is an alignment of development and IT operation.
Agile Vs. DevOps Vs. Scrum Comparision
As we briefly discussed Agile, DevOps, and Scrum, let’s compare these individually.
Agile methodology is a process of managing a project by separating it into multiple steps. It allows constant collaboration between stakeholders and continuous improvements at every stage. Once a project begins, the development team continuously follows the process of planning, evaluating, and executing until the task gets accomplished. Continuous collaboration is crucial between both the development team and project stakeholders.
DevOps is a software development approach that extends the agile development principles by integrating the development and operation units of the IT team. This integration allows a seamless flow between traditionally siloed sides of the software development lifecycle. Furthermore, it lessens the defects in production because the operati0n requirements are considered from the beginning of the project.
DevOps project management is like a union between two disciplines where project management supports the DevOps model. In the DevOps project management methodology, the project managers work as coordinators among contributors and track the timeline and dependencies. Besides, the project managers must remain aligned with the DevOps team and bring an intensive understanding of the development process and mastery required to develop the product. There are numerous practices that project managers can or should follow to make this integration with the DevOps pipeline.
Scrum project management is one of the well-known agile methodologies project managers use. In Scrum project management methodology, the project manager leads the project team. It comprises project owners, product owners, Scrum masters, and cross-functional team members. While the product owner is accountable for maximizing the product’s value, the Scrum master is responsible for ensuring the project team follows the Scrum methodology.
The Scrum methodology is characterized by short phases, aka sprints, when project work begins. While spring planning, the team identifies a small part of the scope to accomplish during the upcoming sprints— which is generally a period of two to four weeks. The work must be completed to get delivered to the clients by the end of the sprint. Eventually, the sprint ends with the sprint review and retrospective. This cycle continues throughout the lifecycle unless or until the whole scoop is delivered.
Differences Between Agile, Scrum, And DevOps
- While Agile emphasizes collaboration between developers and product management, DevOps also includes operation teams.
- Agile centers account for the flow of software from ideation to code completion; on the other hand, DevOps extends the limit by focussing on the delivery and maintenance.
- Agile adds structure to planned tasks for developers; the DevOps incorporates work with no plan typical to the operation team.
- Agile follows iterative development with small batches, whereas DevOps focuses on testing and delivery automation.
- While Agile is a philosophy, Scrum is a kind of Agile methodology.
- Agile involves members from different cross-functional teams, whereas the Scrum project team involves specific roles, for instance, the Scrum master and product owners.
- While Scrum is separated into shorter sprints and smaller deliverables, In Agile, the project gets delivered by the end of the project.
It’s worth remembering that although Scrum is an Agile methodology, Agile isn’t always Scrum; many other methods take an Agile approach for managing projects.
Agile, Scrum, And DevOps: Which Is The Best For Your Project
As you know all the facts, pros, and cons of Agile, DevOps, and Scrum, you can choose one of these per your project’s requirements.
