Project management & developed can be confusing to beginners. Some may even consider Agile & Scrum to be of similar methodologies. So before differentiating the agile and scrum, we need to know some basic information about agile and scrum. So, let’s start with the meaning of agile development.

Agile Development

Agile development is a software development approach which evolves the requirements and solutions through the collaborative efforts of self-organizing teams. It describes a set of guiding principles that uses an iterative approach for software development.

It involves adaptive planning, evolutionary development, early delivery, and continual improvement, and it encourages rapid and flexible response to change. And you should’ve already thought that Agile and Scrum are not the same things. So, we’ll dig a deeper to clean up the doubts.

Why use Agile software development?

Here we have covered some pretty impressive statistics that prove the success of companies who adopted Agile software development methodology.

As per the Project Management Institute, more than 75% of agile organizations accomplished their goals and business intent.

More than 65% of organizations finished their projects before or on time

More than 69% finished their projects within budget

But on the other, those firm and organizations who are using traditional or old software development have shown lesser growth rate. The research shows that agile organizations grow revenue 37% faster and earn 30% higher profits than non-agile companies.

Agile software development is realistic in nature. By using agile, even small business ideas grow exponentially, things change all the time, and teams need to be able to adapt to these changes. And agile helps to clarify what work is to be done, what didn’t and accordingly help in adjusting workflow. This empowers to improve team constantly.

History

At the beginning of the mid-nineties, there were many practitioners, either they work themselves inside the organizations for the development of agile or hire consultants for building software who thought, you know what?

The way we’ve been developing software just isn’t working for us. This way is too slow and unproductive. We’ve got to come up with something different and new.

Most of the developers started mixing old and new ideas, and when they found a combination that worked, they crafted a methodology for the team to help them remember the aggregate of ideas that worked in a given situation.

Jeff Sutherland is now considered the godfather of Agile software development.

Advantages:

  • The software Updated quickly and thus helps in increasing the satisfaction and trust of the customer.
  • Has the ability to adapt to changing requirements and respond to them quickly rapidly.
  • Feedback is so immediate that it helps in improving the software in the next increment.
  • People are considered more important and given a higher priority rather than process and tools.
  • Agile involves continuous attention to technical excellence and good design.

Disadvantages:

Generally, in the long projects, it is difficult to assess the effort required at the initial levels of software development life cycle, so there could be a wrong HR policy that may risk the existence of the company in future.

This software development is more code-focused and thus produces less documentation.

For Agile customers are at a high priority. It is heavily based on the inputs of the customer. If the customer has an ambiguity in his vision of the final outcome, it is likely for the project to get off track.

Generally, face to face communication is not possible or difficult in large-scale organizations.

The decision-making policy is stuck in the hands of senior programmers. Only they are capable of taking the kind of decisions required during the development process. Thus, it demotivates the new programmers to take the initiative and adapt to the environment.

Detailed Difference between Agile and Scrum

Agile is a development methodology that is based on iterative and incremental approach. It encourages rapid and flexible response to change.

Scrum is one of the implementations of agile methodology. In simple, scrum is a part of agile where the incremental builds are delivered to the consumer in every two to three weeks’ time

Agile software development is considered highly suited to environments which have small but expert project development team, as it evolves the requirements and solutions through the collaborative efforts of self-organizing teams.

Following are Agile principles:

-It welcomes graduating requirements even late in development. That helps to improve immediately to grab customers competitive advantages.

– Team members and program developers work hard daily throughout the project.

-The focus on technical excellence and right design enhances agility

The team support is more effective, and they adjust their behavior according to the project.

Following are Scrum principles:

It mainly focuses on self-organization that results in healthier shared ownership among the team members. It also creates an innovative and creative environment which is beneficial to growth.

-The second principle is coordination. Coordination is another essential principle which focuses on work should be done with team spirit. And the team can together offer the highest value.

-The third principle is Time-boxing: This principle states how time is restraint in the Scrum method. So, it conducted Daily Sprint planning and Review Meetings for faster completion of tasks.

Conclusion:

Agile is a development methodology that is based on iterative and incremental approach. It encourages rapid and flexible response to change.

In the Agile method, the priority is given to customers. It always gives importance to the satisfaction of employees by always to satisfy by providing continuous delivery of valuable software.

But Scrum, on the other, is an agile process that focuses on delivering the highest business value to customers.

The main advantage of the Agile method is its flexibility as it accepts feedback even at late in-the process and quickly reacts to changes.

Leadership plays a vital role in the agile method.

And in Scrum, for faster completion of tasks daily sprint meeting is conducted to review and feedback to decide future progress of the project.

Additionally, in Scrum, when the team is finished with the current task, the next task can be planned only.
