Today we will talk about two development methodologies that are currently being used by the majority of the software companies in the world. Agile, and DevOps.
Should I use one or the other? Why should I choose one and not the other? What are the benefits of each one of them? These are the type of questions we will be answering in today's article.
What is DevOps?
DevOps is a software development methodology that connects teams. It connects the software team with the operations team. Forming what the name stands for, a connection between development and operations.
Historically, these teams have always worked independently and separately, but with the pass of time, consultants and companies started to recognize that It was a very efficient way to work.
DevOps aims to increase efficiency and shorten the time to market from the design to the launch. As the teams are connected, the development is also connected. By using this methodology, operations team members are part of the development, and ensure that the product is suitable in operational standards. The same thing, on the other hand, developers work with operations, making sure the operations are suitable for development standards.
What is Agile?
Agile, is a software development methodology that started in 2001. The software methodology is the most currently used methodology in the startup world as well as in the corporate world.
The methodology is based on values and principles that are written in a document. The document is named the "Agile Manifesto" and there are 4 values and 12 principles. The Agile methodology looks to align development with the most relevant customer needs.
- Individuals and interactions over processes and tools
- Working software over comprehensive documentation
- Customer collaboration over contract negotiation
- Responding to change over following a plan
- Customer satisfaction through early and continuous software delivery
- Accommodate software requirements throughout the development process
- Frequent delivery of working software
- Collaboration between the business stakeholders and developers throughout the project
- Support, trust and motivate the people involved
- Enable face-to-face interactions
- Working software is the primary measure of progress
- Agile processes to support a consistent development pace
- Attention to technical detail and design enhances agility
- Self-organizing teams encourage great architectures, requirements, and designs
- Regular reflections on how to become more effective
The agile mindset is based on psychology. It focuses on people rather than on tools. Through its processes, it aligns the most common development standards with the most urgent customer requests. It's a good methodology to discover new trends and increase your value proposition.
While most would think they have to choose one, and it can be done too, there's nothing stopping companies to adapt both methodologies at the same time. The most important thing is to recognize which project needs which methodology. If you are needing to connect small teams, then Agile maybe your best call. If you are looking to develop connecting larger teams, then DevOps is your best practice.
Both methodologies aim for the same, but they work differently. Agile develops in the way of Sprints. Small iterations of development over time. While DevOps develops on many short-time releases that also iterate over time. The schedule of each methodology is what makes them different. Agile pushes development away from the traditional and conventional work environment. DevOps communicate teams in a way where the departments are not separated but connected as one.
Agile has been tried and tested and the results are effective. It does count with one challenge: making it work in big corporations. Most corporations are choosing DevOps or other methodology that adapts better for larger teams. In the startup world, Agile is the leading methodology up to date.
DevOps has its challenges too. If not applied in the right way, DevOps can become a burden rather than something that sums positively to the company. If the releases are not timely and short framed, then the failure of the methodology arises.
Several companies are using both methodologies at the same time. Contrary to the expected result, the use of both complements and empowers the other. You can use both simultaneously. A company named BoxBoat "uses te agile methodology to build a DevOps culture" says the CTO. As both have their benefits and their complementary differences, they choose both. The goal is to create further collaboration. Not making the company be an Agile environment neither a DevOps environment. This company finds out that the combination of both is what they needed the most.
In conclusion, there are two major software development methodologies. Agile methodology and DevOps methodology. They both differ but they both aim for the same thing: increase productivity, develop and release efficient software. They both work with different schedules, Agile uses Sprints to develop. Sprints may take between one day up to one year. The software is developed by iterations. DevOps uses fast-paced weekly updates and releases. Agile is used by most startups, and DevOps by bigger corporations.
