Wrap up

Let us understand Agile first before understanding its frameworks.

What is Agile?

Agile is an iterative method to software development that produces software progressively from the beginning of a project rather than attempting to deliver it all at once near the end. The agile team works on small sections rather than working on a big launch. Hence, this technique enables teams to offer value to clients more quickly with lesser difficulties.

Let us learn about the Agile manifesto

Agile Manifesto

The term ‘Agile’ originally appeared in the Agile Manifesto.

This term should conjure up images of adaptability, agility, and response to change.

According to the Agile Manifesto:

What exactly does Agile Software Development involve?

One of the most basic and efficient techniques for transforming a vision for a business requirement into software solutions is the Agile software development strategy. Continuous planning, learning, improvement, team participation, evolutionary development, and early delivery are all used in agile software development approaches. It encourages adaptive responses to change.

Frameworks for agile development

Scrum, Kanban, and Scrumban are the most popular Agile frameworks today.

Scrum is widely used, has a sound theoretical foundation, and serves as a suitable foundation for other frameworks. Hence, we will concentrate on it in this post. Scrum’s fundamental goal is to fulfill customer demands through an environment of communication transparency, shared accountability, and continuous development.

Scrum

Scrum is a framework that facilitates teamwork.

It is a methodology for addressing complex adaptive issues while producing high-value solutions productively and creatively.

What is Scrum?

Scrum is a methodology for agile software development built on iterative and incremental procedures.

Scrum is an agile framework that is adaptable, fast, flexible, and effective at delivering value to the customer throughout the project’s progress. Scrum’s fundamental goal is to fulfill the customer demands through an environment of communication transparency, shared accountability, and continuous development.

Scrum Basics

Scrum basics are empiricism and lean thinking. According to empiricism, knowledge comes from experience and decisions based on observation. Lean thinking focuses on the fundamentals while reducing waste.

Scrum takes an iterative, incremental approach to predictability and risk management. 

Transparency, inspection, and adaptability are the foundations of scrum in software development. 

  • Transparency – Process and work that emerge must be apparent to both people who do and receive the work. Important Scrum choices are dependent on the perceived status of the three formal artifacts that make up the framework. Low-transparency artifacts can lead to judgments that reduce value and raise the risk.
  • Inspection – It is necessary to regularly inspect the progress towards established goals to discover potentially undesired deviations or issues. Scrum delivers rhythm in the form of its five events to aid inspection.
  • Adaptation – If any part of a process deviates beyond acceptable boundaries, or if the final product is unsatisfactory, it is necessary to rapidly adapt the changes to the process and perform the necessary corrections. 

Scrum Team Roles

Scrum’s fundamental unit is a small group of individuals known as a Scrum Team. The Scrum Team consists of a Product Owner, a Scrum Master and Developers.

Scrum Team: Product Owner

The key responsibilities of product owner include: 

  • To create a Product Goal that outlines the product’s future state. The team will plan their future work based on this.
  • To build the Product Backlog: a list of all the tasks/items that the team must do.
  • To boost the value of the Scrum Team’s efforts. In other words, it comprises the responsibility for defining work priorities and organizing work for the following period with the team.

Scrum Team: Scrum Master

The Scrum Master primary responsibilities are as follows:

  • To ensure that everyone in the team knows and applies the Scrum principles correctly.
  • To ensure the effectiveness of the team by removing barriers and providing conducive working circumstances.
  • To facilitate the creation of product backlog items or in the establishment of the Product Goal.

Scrum Team: Developers

Developers’ primary responsibilities are as follows:

  • To construct a Sprint Backlog plan by selecting specific activities that will satisfy the Sprint Goal (the goal of a particular period).
  • To align their daily work schedule with the Sprint Goal.
  • To be experts in the field.

Scrum events 

There are five major events in the Scrum cycle. Each Scrum event aids in the adaptation of certain parts of the process, the product, the progress, or the relationships.

Sprint: A Scrum team’s basic unit of work is the sprint. It is the key feature that sets scrum apart from other agile development methodologies.

Sprint Planning: Sprint Planning begins by laying out the tasks that must be performed throughout the Sprint. The Scrum Team’s collaborative efforts result in the final plan.

Daily Scrum: The Daily Scrum aims to assess progress and trends until the end of the Sprint and establish a strategy for the next 24 hours. It is a brief meeting held every day during the Sprint phase. Individually, three questions to be answered: What did I do yesterday? What do I have planned for today? What support do I require? The Scrum Master should make every attempt to resolve any challenges or barriers that may arise.

Sprint Review: The sprint review’s purpose is to illustrate what work has been accomplished on the product backlog for future delivery. The completed sprint is assessed, and there should be a visible and demonstrable improvement in the product to deliver to the client.

Sprint Retrospective: The Scrum Team determines the most beneficial adjustments to make to increase its performance. The Sprint Retrospective brings the Sprint to a close. For a one-month Sprint, it is limited to a maximum of three hours. The event is generally shorter for shorter Sprints.

Scrum Artifacts

Scrum Artifacts ensure that critical information is transparent during decision-making.

  • Product Backlog (PB): The backlog lists everything a product needs to delight potential consumers (PB). It is designed by the product owner, and functions are prioritised according to how important they are to the business. The product owner’s objective is to provide a solution to the issue “What should be done?”
  • Sprint Backlog (SB): The team picks a subset of product backlog items that will be completed during the sprint in a Sprint Backlog (SB). The timing of each sprint is determined by each team. Everyone can see what’s in the sprint backlog because it’s posted on real Scrum boards.
  • Increment: The increment is made up of all the tasks, use cases, user stories, and product backlogs that were produced throughout the sprint.

Benefits of Scrum development 

Scrum outperforms other agile development methodologies in a variety of ways. In the software industry, it is presently the most frequently used and acknowledged reference framework. The following are some of Scrum’s well-known benefits:

  • Changeable: Quick response to changes in requirements caused by consumer needs or market developments. The technique is intended to adapt to the shifting requirements that come with complicated projects.
  • Reduced time to market: The client can begin utilizing the most critical features of the project before the product is finished.
  • Better software quality: The work approach to provide a usable version after each iteration results in higher software quality.
  • Timely Prediction: Using this technique, we know the team’s average sprint pace, which allows us to predict when a certain functionality that is still in the backlog will be ready.
  • Scalable: Scrum procedures are iterative and managed inside specified work intervals, which allows the team to focus on definite functionality for each period. This not only results in better deliverables that are more in line with the demands of the user, but it also allows teams to scale the modules in terms of functionality, design, scope, and characteristics in an orderly, clear, and easy manner.
  • Risk reduction: Knowing the pace at which the team progresses in the project and carrying out the most important functionality first aids in the removal of risks in advance.

Scrum cons 

  • If a team or a whole organization does not fully grasp Scrum as described in the Scrum Guide, the danger of misunderstanding it is significant.
  • Scrum’s success depends on all team members being equally engaged and interested.
  • Scrum is not appropriate for maintenance tasks, for example.

When should Scrum be used?

Scrum is worthwhile to use if and only if:

  • It is the very beginning of Agile collaboration – it helps to learn effective techniques and use them later.
  • Projects do not have well-defined needs at the start, and the project appears to be difficult – Scrum allows for collaborative work and requirement clarification during the development process. The specifications may also change.
  • The team has less than ten members; if the team is bigger, it can be broken into numerous Scrum teams that work on the same Product Goal.

Wrap up

Scrum and its fundamentals may be quite beneficial in structuring a team’s work from the start. This framework is a well-profiled skeleton of the essential principles, which may appear easy but may be difficult to apply.

It’s important to dive into this framework and study it thoroughly from the outset of app development. Even if you’ve already begun your current project, we strongly advise you to review the Scum guidelines regularly.

As soon as the team feels secure in this framework, they may begin experimenting because Scrum allows for a great deal of self-interpretation and additional customization. We hope this post helps you understand what Scrum is and how it is used in software development.
