What is Agile methodology?
When the software industry started it was depended on the traditional Waterfall methodology. The traditional process was time-consuming and had limitations which are not applicable in the ever-changing world of the software development lifecycle (SDLC).
In 2001, from February 11-13; there was a meet at ‘The Lodge’ at Snowbird ski resort in the Wasatch mountains of Utah; where a group of seventeen people came up with the idea of a new way to implement software development. It would accelerate the production procedure and will have lesser time to market providing more time for the developers, testers and support teams to look into other areas of software development.
This process is known as Agile methodology. It works on the iterative development approach where customer involvement is the priority. Here the deployment rate is much faster, there is regular monitoring and discussion on the progress resulting in fewer deployment issues and steady progress.
What is Scrum?
According to Scrum.org, the definition of Scrum is ‘Scrum is a framework within which people can address complex adaptive problems, while productively and creatively delivering products of the highest possible value.’
Scrum is a framework within Agile methodology to accelerate production and make it more streamlined. It was initiated by Ken Schwaber and Jeff Sutherland. They have created a ‘Scrum Guide’ that gives an outline of the ways to implement Scrum in the Agile methodology.

The three major aspects of Scrum are:
- It is lightweight
- It is simple to understand
- It is difficult to master
Although Scrum is an answer to faster error-free delivery to increase productivity. Still while implementing it must be kept in mind that Scrum is a lightweight software application that is quite easy to access and implement however without proper expertise it is quite difficult to master; so proper guidance and patience are the keywords to have a successful Scrum practise.
The difference between Agile and Scrum
Agile |
Scrum |
|
| 1. | Agile is a software development methodology that is based on an incremental iterative approach. | Scrum is a framework implemented within Agile which uses incremental builds to deliver. |
| 2. | Leadership is an integral part of Agile methodology; it is suitable for environments that have a small but highly efficient development team for projects. | Scrum, on the other hand, is based on self-organizing and have cross-functional teams that do not require leadership. It is most suitable for environments that require rapid changes. |
| 3. | Agile is more rigid than Scrum and there is not much room left for change. | Scrum is more flexible and has an instant reaction to changes |
| 4. | In Agile there is strong collaboration through face–to–face communication between team members and the cross-functional teams at large. | Scrum, on the other hand, collaborates and communicates through stand-up meetings held daily along with fixed roles assigned to the team members, scrum master and the product owner. |
| 5. | The delivery tenure for Agile is not fixed but usually frequent, usually known as continuous delivery (CI). | For Scrum, the delivery is always after each ‘sprint’ that are for fifteen days, so after every fifteen days, there is a delivery. |
| 6. | Design and execution are always kept simple for Agile | Scrum is more innovative and experimental with the implementation of the design. |
| 7. | In an Agile approach, the customer is the king, so there is regular feedback from the customer during the process for the development of the product. | Scrum involves team members and feedback through daily sessions that are conducted in the stand-up meeting among the teams. |
Conclusion
The world of software development is fast and ever-changing. if you want to sustain in this ever-evolving world you must be swift and utilize opportunities to keep up with the changes. Here time is the most important aspect of success. A software produced a few months back needs constant updates to run it smoothly. There is no time to waste and the Scrum framework helps you to achieve this within no time. Therefore, Agile methodology is the preferred approach while the Scrum framework is a comprehensive practice to accelerate Agile.
