Introduction

Some people often wonder: are agile and scrum the same? There’s a lot of confusion out there. We saw a thread on Stack Overflow on this topic that was full of complete nonsense. So we thought we would clear things up. Short version: agile and Scrum are NOT the same. Now I’ll get into what each one is and why that is the case. The advantage of this is the flexibility of being able to react quickly to changes in requirements and the priorities of the business. Agile solves the problem of waiting long periods of time before development can begin. It also solves the problem of adjusting large development schedules and budgets when inevitable changes come.

So, with that introduction, what distinguishes Scrum from other Agile methodologies? Scrum is a particularly simple and flexible Agile methodology. Actually, Scrum may be used as a methodology for producing any product and has been used in the manufacturing process as well as software development.

Here is a great video about the difference between Scrum and agile:

  • Agile

Agile software development methodology is more adaptable to changes as there is no in-depth planning at the beginning of a project rather there are changing requirements throughout the course of the project. Constant feedback from the end users is encouraged. In Agile, there is an incremental and iterative development approach. The work is prioritized on the basis of business or customer value. There are cross-functional teams that work on the iterations of the product over a period of time. Each iteration is focused on producing a working product.

Agile refers to a process that is aligned with the concepts listed in the Agile Manifesto.

Benefits the Customers

In the traditional waterfall model, the high-value features are developed and delivered in longer cycles compared with the agile methodology, which enables delivery inside short cycles. This enables the vendors to be more responsive to the development requests of the customers.

Benefits the Vendors

Adopting Agile benefits the vendors by having improved consumer satisfaction and customer retention, leading more customer contacts through positive references. The Agile allows the vendor’s focus to be on the development exertion of high-value features, decrease the overheads, and develop efficiency.

Quality

With Agile development, there is a general inspection of the working product, with testing integrated at every iteration, as it develops all through the life cycle. This turn retains the quality of the product and furthermore allows the product owner to make necessary adjustments at whatever point a quality issue arises.

Visibility

An agile methodology is a collaborative approach that encourages active customer participation all through product development. This gives exceptional and clear visibility of the project’s progress and product development to the stakeholders.

Cost Control

The agile development process has fixed timescale where the requirements emerge and evolve as the project progresses and the product is developed. This enables a fixed budget.

Risk Management

In Agile methodology, small incremental releases are made visible to the product owner all through the development cycle, which recognizes issues at an early stage, and it makes easier to respond to change if any. agile development ensures clear visibility, which allows necessary decisions to be taken at the earliest possible opportunity.

  • Scrum

Scrum, then again, is a subset of Agile. A Scrum is a simple and flexible agile methodology for software development. The Scrum isn’t a technique or a process but a lightweight and simple framework to address complex problems of a project and deliver a high-value product creatively. The major distinguishing attributes of Scrum are as follows:

Simplicity

The development in Scrum is done in sprints, which are 1, 2, and 3 weeks in length. The Scrum team consists of:

#1- Product Owner: The major responsibility of the product owner is to maximize the value of the product and work of the development team. Additional duties include managing the product catalog.

#2- Scrum Master: The development team consists of self-organizing professionals who turn the product catalog into product increment at the finish of each sprint.

#3- Development Team: The Scrum Masters make sure that the Scrum team is abiding by the Scrum theory and its rules.

Flexibility

In the traditional waterfall model, when the business and technical requirements are documented and detailed, it results in endless documentation. The Scrum makes use of user stories to describe the functions needed to be developed. A tool called Pivotal Tracker is used to store these user stories in a backlog. On the off chance that a change needs to be made or a need arises to add to the user stories, all things considered, the team can adjust as early as the next sprint. This allows the business to change their minds and the development team to be flexible enough to adjust to those changes. The ability to accommodate change is a powerful -attribute of the Scrum methodology.

Communication and Collaboration

In the Scrum methodology, the communication between business users takes place on a  daily/weekly basis according to the sprint schedule. This close communication and collaboration effort is a crucial factor, promoting the success of the Scrum methodology. The Scrum team accomplishes achieves collaboration in the following ways:

#1- The Product Owner, the Scrum Master, and the development team work closely on a daily basis.

#2- Sprint planning meetings are conducted, which allows the development team to organise its work based on the knowledge gathered from the business priorities.

#3– Conducting daily scrum meetings where the development team can account the work finished, its future prospects, and deal with issues if any.

#4- Conducting sprint reviews allows the team members to evaluate their former work by recommending better practices with each sprint.

Conclusion

Agile is the software development methodology that focuses on customer satisfaction by delivery shippable software frequently. Scrum is one of the many approaches to implement Agile. Scrum is suitable for a certain type of projects where there are rapidly changing requirements.
