Are you ready to discover the main differences between Agile and Scrum methodologies? This blog explains the features, roles, and principles of both Agile and Scrum software developments. As we know that these two software development tools emerging as powerful iteration methods. Most of the software as well as other organizations are developing their software products with the help of these methodologies. So let's get started to learn the main differences and roles of both Agile and Scrum software developments.
Agile is nothing but one of the software development methodologies that approaches the development requirements and solutions. This can be performed through the collaboration of self-organizing, cross-platforms usage, and also with their customers or end-users. Agile software was developed in the year February 17th, 2001 at Utah software developers’ conference. Firstly they called it "Manifesto for Agile software developments' ' now we call it as Agile methodology. They have come up with 12 main principles of Agile, to support cross-functional iterations. The main purpose to use Agile in the software development life cycle is to support adaptive business planning, evolutionary product developments, iterative approach towards the software, encouraging the team to perform flexible changes, and delivery.
Scrum is nothing but an agile framework used in the developments, delivery, and sustainable complex software products. This model also offers initial emphasis for the software development lifecycle, and also the Scrum model has been used in many applications such as research, sales and marketing, and also advanced business technologies. In simple terms, it can be defined as a subset of the Agile model and the most widely used process framework.
The Scrum was first introduced by Jeff Sutherland and Ken Schwaber in the early 2000s.
In this section, I am going to explain the major differences between Scrum and Agile methodologies,
|Agile is a software development lifecycle methodology, this Agile model is mainly used for software iterations or functional incremental purpose.||Scrum is a subset of Agile iteration methodology, it helps to deliver increment functional models to the clients; this can be done every two weeks once.|
|Agile software development life cycle is a widely used model, due to its higher development priorities to the environments this may consist of small expert teams.||Scrum is ideally used in the project where the requirements are rapidly changing.|
|In the Agile methodology process, team leadership plays a key role.||Scrum mainly focuses on the self-organizing and collaboration of the cross-functional teams.|
|The biggest advantage of Agile is its flexibility as it quickly reacts to changes||Compared to Agile it is a more rapid method. So there is not much room for frequent changes.|
|Agile involves collaborations and face-to-face interactions between the members of various cross-functional teams.||In Scrum methodology, project collaboration is achieved through regular team stand up meetings to discuss the role assigned to the scrum master team, project owner, and project team members.|
|Agile can require lots of up-front development process and organizational change.||Scrum doesn’t need too many modifications while implementing the scrum process.|
|The Agile method, team members should update on the frequent delivery of the product. They should wait for end-users final feedback.||In the scrum, after completion of each product sprint, and they deliver the final product and also wait for the end-users feedback.|
|In this method, each step of development like requirements, analysis, design, is commonly monitored during the life cycle.||A demonstration of the functionality is provided at the end of every sprint, so that regular feedback can be taken before the next sprint.|
|All tasks are managed and taken care by project head||Any issue or challenges are addressed by the entire team|
|Customer satisfaction is the top-most priority||Philosophy of scrum-based processes are empirical process control|
|Face-to-face communication is emphasized to achieve a goal.||The key focus is on delivering the maximum business value.|
|The fundamental measure of progress working software.||Working software is not considered as a fundamental measure of progress.|
Agile methodology in general uses the short project development lifecycle to produce continually integrated into software development. This methodological approach is mainly focused on delivering iterative and incremental services throughout the project development life cycle. Agile methodology reduces the risk in the project plan, requirement building, execution of the product, testing the product by breaking the big cycle into smaller segments. Then these small segments or the final product will be specified, developed, and testable in the maximum three-four weekly cycle.
There are 5 types of Agile methodology process available:
1. Evaluation of the process and current structure of the organizations:
This Agile methodology supports the mapping processes to determine the starting point and the actual state.
2. Process optimization and suggestion for improvements:
Helps to optimize the processes with the right combination of the technologies.
3. Helps in the designing of applications with the client:
We choose the technologies and review options with the client. The client is a part of the project from the very beginning and feedback is vital.
4. Application constructions and implementations:
Enables weekly delivery of developments for the end-users to operate and request for change. It is IDEAL that the user is a part of the process of development and testing.
5. Evaluation and Monitoring:
These determine the KPI's, reports, and other matrices, per user. To monitor that the processing is working as agreed.
12 primary principles in Agile methodology explain there are 12 primary principles in Agile methodology that explain the overall working structure of the software development lifecycle.
1. Agile always focuses on customer satisfaction, that's the highest priority and it can be achieved through faster and continuity in the product delivery.
2. This enables users to change the project environment at any stage of the lifecycle process to offer the clients with standard advantages.
3. With the help of Agile methodology, any type of product or service can be delivered with higher frequencies.
4. Agile methodology helps the stakeholders and business developers to collaborate closely on a daily work basis.
5. The company's team members and all the stakeholders will be motivated continuously for the optimal project or service outcome, while the company's team members are provided with all the necessary fundamental tools and encouragement to work towards the final project goals/outcome.
6. Face-to-face meetings are considered to be the most efficient and effective source for any project success.
7. A final working service/product will be the ultimate measure of project success.
8. The sustainable development environment will be available through the agile methodology process, thereby development team members and stakeholders will be able to maintain an ongoing pace and constant outcomes.
9. Agility is possible through the continuous focus on software technical excellence and proper project planning.
10. Simplicity is an essential part of the software development lifecycle.
11. This makes self-organizing business teams develop the best project architecture and designs ever.
12. Regular time intervals are used by the company's team members to improve efficiency and optimization.
There are a lot of advantages that make Agile the most popular model nowadays. I would like to mention a few primary advantages of Agile model:
1. Offers better product quality: testing is integrated into the software life cycle with regular checkups and enabling product changes if they needed it.
2. Customer satisfaction is the highest priority:
The software product is involved in the process and this makes the customer part of the project.
3. Provides more control on the project:
This offers more transparency in the development and designs, short customer meetings, visibility of every step of the project during the development life cycle.
4. Risk reduction:
The risk of total failure and elimination as there is a constant contract. There is the freedom to add new changes throughout the process and adapting them to client preferences.
5. Faster Return on Interest (ROI):
With the use of Agile iteration, the features will be delivered soon, developers will be having benefits from the beginning to the complete project outcome.
Even with a lot of advantages of Agile methodology, there are also few drawbacks of Agile models. Let me mention a few points;
1. Longer length in each iteration or increment.
2. Cannot accommodate changes anytime.
3. Lack of user involvement throughout the life cycle of the product.
4. Costly for dynamic development environments.
5. Assume that future changes will not occur.
Scrum methodology in detail:
The Scrum methodology is nothing but the overall process of the model, which explains the task or operations performed by the model.
Steps are as follows:
There are lots of key factors, which make Scrum a popular iteration tool. I would like to mention the primary advantages:
Even with lots of advantages make Scrum in more demand, but few drawbacks also there, let me make a few points:
In this blog, I have tried my level best to explain the two popular iteration methodologies, they are Agile and Scrum master. Agile helps in the iteration of the product and cross-functionalities incremental. Whereas scrum is a subset of agile methodologies widely used in team meetings and collaborations. I hope this article may help a few of you to learn and know the major differences between these two methodologies and also for Agile community forums.
