You Must Know: Major Differences Between Scrum and Agile

Scrum Methodology

What Is Scrum?

Scrum is a subset of Agile and one of the most successful process frameworks for performing Agile. It is an iterative software development standard used to manage complicated software and product development. Fixed-length iterations, called sprints lasting one to two weeks long, permit the team to ship software on a regular flow. At the end of each race, stakeholders and team members meet to plan next steps.

Scrum follows a set of roles, responsibilities, and agreements that never change. For example, Scrum calls for four services that provide structure to each sprint: sprint planning, regular stand-up, sprint demo, and sprint retrospective. During each race, the team will use visual artifacts like task boards or burndown charts to show progress and receive incremental feedback.

Advantages of Scrum

Scrum is a highly rigid framework with particular roles and functions. While it can be a lot to learn, these rules have several advantages. The advantages of Scrum include:

More Clarity and Project Perceptibility: With daily stand-up meetings, the whole team understands who is doing what, eliminating many misunderstandings and trouble. Issues are identified in advance, enabling the team to solve them before they get out of hand.
Raised Team Accountability: No project manager is telling the Scrum Team what to do and when. Instead, the team collectively determines what work they can make in each sprint. They all work together and support each other, increasing collaboration and empowering each team member to be independent.
Simple to Modify Changes: With short sprints and constant feedback, it’s easier to cope with and provide changes.
Increased cost savings: Constant communication guarantees the team is aware of all issues and changes as soon as they arise, helping to lower costs and improve quality. By coding and testing features in smaller parts, there is continuous feedback and mistakes can be fixed early on, before they get too expensive to fix.

Disadvantages of Scrum

While Scrum gives some actual benefits, it also has some downsides. Scrum demands a high level of experience and commitment from the team and projects can be at risk of scope creep.

Here are the disadvantages of Scrum:

Risk of Scope Edge: Some Scrum projects can experience scope creep due to a reduction of the specific end date. With no completion date, stakeholders may be invited to keep requesting additional functionality.
The Team Needs Experience and Commitment: With defined roles and responsibilities, the team wants to be familiar with Scrum principles to succeed. Because there are no established roles in the Scrum Team, it requires team members with technical experience. The team also wants to commit to the regular Scrum gatherings and to stay on the side for the term of the project.
The Wrong Scrum Master Can Destroy Everything: The Scrum Master is very varied from a project manager. The Scrum Master does not have authority over the team; he or she needs to take the team they are managing and nevermore tell them what to do. If the Scrum Master decides to control the team, the project will fail.
Inadequately Defined Tasks Can Lead to Imprecision: Project costs and timelines won’t be accurate if functions are not well established. If the initial goals are unclear, planning matches difficult, and sprints can take more time than initially estimated.

Roles in Scrum

There are three particular roles in Scrum. They are:

Product Owner: The Scrum Product Owner has the vision of what he or she wants to make and carries that vision to the team. The Product Owner centers on business and market requirements, prioritizing all the work that requires to be done. He or she builds and manages the supply, provides guidance on which stars to ship next, and communicates with the team and other stakeholders to make satisfied everyone gets the items in the product backlog. The Product Owner is not a project manager. Instead of maintaining the status and progress, his or her job is to move the team with a purpose and vision.
Scrum Master: Often thought the vehicle for the team, the Scrum Master encourages the team does their best potential work. This means organizing meetings, dealing with roadblocks and challenges, and working with the Product Owner to assure the product supply is ready for the following sprint. The Scrum Master also makes sure the team understands the Scrum method. He or she doesn’t have power over the team members, but he or she does influence the process.
Scrum Team: The Scrum Team is composed of five to seven members. Everyone on the project works together, helps any other, and shares a deep sense of comradeship. Unlike traditional development teams, there are not different roles like programmer, designer, or tester. Everyone makes the set of work together. The Scrum Team owns the plan for each sprint; they predict how much work they can achieve in each iteration.

Agile Methodology

What Is Agile?

Agile software development is based on an incremental, iterative path. Alternatively of in-depth planning at the start of the project, Agile methodologies are open to changing elements over time and promotes regular feedback from the end users. Cross-functional teams work on iterations of a product over some time, and this work is organized into a supply that is prioritized based on business or customer value. The goal of each emphasis is to produce a working product.

In Agile methodologies, leadership encourages teamwork, responsibility, and face-to-face communication. Business stakeholders and developers need to work together to align the product with customer requirements and company goals. The Agile Manifesto is a moving variation to the traditional book A Guide to the PMBOK Guide and standards.

Advantages of Agile

Agile emerged from different lightweight software approaches in the 1990s and is a response to some project managers’ reluctance of the rigid, linear Waterfall methodology. It concentrates on flexibility, constant improvement, and activity.

Here are some of the top advantages of Agile:

Change Is Included: With shorter planning cycles, it is easy to adapt and allow changes at any time during the project. There is always an opportunity to adjust and reprioritize the backlog, letting teams introduce changes to the project in a matter of weeks.
End-Goal Can Be Far: Agile is very beneficial for projects where the end-goal is not explicitly defined. As the project proceeds, the goals will come to light and development can quickly change to these evolving requirements.
High-Quality Delivery: Breaking down the project into repetitions enables the team to focus on high-quality development, testing, and collaboration. Managing to test during each iteration means that bugs get identified and solved more quickly. This high-quality software can be delivered faster with consistent, consecutive iterations.
Powerful Team Interaction: Agile highlights the value of precise communication and face-to-face interactions. Teams work together, and people can take responsibility and own shares of the projects.
Customers Are Learned: Customers have many chances to discuss the work being delivered, share their input, and have a real influence on the end product. They can get a sense of ownership by working so intimately with the project team.
Continuous Development: Agile projects further feedback from users and team members throughout the whole project, so lessons learned are used to develop future repetitions.

Disadvantages of Agile

While the level of compliance in Agile is usually positive, it also comes with some trade-offs. It can be hard to establish a reliable delivery date, documentation can be neglected, or the final product can be very complex than first thought.

Here are some of the disadvantages of Agile:

Plan Can Be Less Accurate: It can sometimes be difficult to pin down a reliable delivery date. Because Agile is based on time-boxed delivery and project managers are usually reprioritizing tasks, it’s possible that some items initially scheduled for transportation may not be complete in time. And, additional races may be added at any time in the project, adding to the overall timeline.
The Team Must Be Aware: Agile teams are usually small, so team members must be highly skilled in a type of areas. They also must understand and feel comfortable with the adopted Agile methodology.
The Team Must Be Aware: Agile is most successful when the development team is wholly committed to the project. Active involvement and collaboration are required throughout the Agile process, which is more time using than a traditional approach. It also means that the developers want to perform to the entire duration of the project.
Documentation Can Be Forgotten: The Agile Manifesto prefers working software over extensive documentation, so some team members may feel like it’s less important to focus on literature. While extensive documentation on its own does not lead to project success, Agile teams should find the right balance between documentation and discussion.
The Final Product Can Be Very Complicated: The primary Agile project might not have a final plan, so the final product can look much different than what was initially expected. Because Agile is so manageable, new substances may be added based on getting customer feedback, which can drive to a much-changed final deliverable.

The Agile Development Cycle

Here are the points in the Agile development cycle. It’s great to note that these phases shouldn’t occur in succession; they are flexible and always evolving. Many of these phases occur in correspondence.

Planning: Once an idea is considered viable and feasible, the project team comes together and works to distinguish features. The goal of this stage is to break down the plan into smaller pieces of work then to prioritize each function and attach it to an iteration.
Requirements Analysis: This form involves many meetings with managers, stakeholders, and users to identify business requirements. The team wants to gather information like who will use the product and how they will use it. These conditions must be quantifiable, relevant, and detailed.
Design: The system and software design is made from the requirements identified in the previous phase. The team wants to think about what the outcome or resolution will look like. The test team also gets up with a test strategy or plan to move.
Implementation, Coding or Development: This stage is all about creating and testing features, and scheduling iterations for deployment. The development phase starts with repetition 0 because no features are being delivered. This emphasis places down the foundation for development, with businesses like finalizing contracts, preparing the environments, and funding.
Testing: Once the code has been generated, it is tested against the requirements to make sure the product is working customer needs and matching user stories. During this stage, unit testing, integration testing, system testing, and approval testing are done.
Deployment: After testing, the product is delivered to clients for them to use. However, implementation is not the end of the project. Once customers start applying the product, they may move into new problems that the project team will need to address.

Agile vs Scrum

Differences and Similarities Between Agile and Scrum

While Agile and Scrum serve the same system, there are any differences when comparing Scrum vs. Agile. Agile defines a set of principles in the Agile Declaration for building software through iterative development. On the other hand, Scrum is a unique set of rules to understand when practicing Agile software development. Agile is the philosophy, and Scrum is the methodology to achieve the Agile philosophy.

Because Scrum is one way to achieve Agile, they both share many similarities. They both focus on delivering software first and often, are iterative processes, and accommodate change. They also encourage clarity and constant improvement.

How Does Scrum Fit with Agile?

Scrum is one of many frameworks used to achieve an Agile method. Agile is an umbrella term that encompasses other means, like Extreme Programming, Kanban, Crystal, and Scrum. Scrum is Agile, but Agile is not Scrum.

When to Use Scrum?

We recommend practicing Scrum if:

The project demands will change and evolve
Continuous feedback is needed
You have to think out how to do a big part of the work because you haven't done it before
You don’t need to commit to a solidified release date
The project team wants autonomy
You need to deliver software regularly

Scrum goes well for projects that have several unknowns or that evolve. Scrum trades with these changes very effectively, so you can comfortably accommodate new information or points throughout the process.

When to Use Agile?

The length between when to use Agile versus when to do Scrum is blurry. Scrum is one framework in the Agile process, so they both have a lot in common. An excellent place to start is first to know if you should use Agile in general. Then, if an Agile methodology looks like it would work for you, you could decide which framework of Agile to use Scrum being one framework.

We recommend using Agile if:

The last product is not clearly defined
The clients or stakeholders need to be able to change the scope
Changes need to be implemented during the entire process
The developers are adaptable and can think independently
You want to optimize for rapid deployment
