what is Scrum in Software Engineering?

Scrum is a framework used in project management that focuses on teamwork and helps teams deliver high-quality products on time. A set of tools, meetings, and different roles are being described in Scrum for timely project delivery. With the help of this framework, the teams or groups self-organize, structure, and manage themselves toward a particular goal and work on that goal to achieve it.

What is Scrum?

In software engineering, scrum is a project management framework that is used to work and self-organize toward a particular goal. With the help of this agile framework, the scrum team performs various practices, meetings, and ceremonies.

1. It uses the process of Iterative and the main advantage of this framework is that it is fast and cost-effective.
2. In the field of software engineering scrum consists of three types of roles- Scrum team, Scrum master, and Scrum owner.
3. Scrum framework is structured which helps the teams or groups to adapt themselves to the requirements of the users.
4. With the re-prioritization built into the process, the team will constantly improve and learn.
5. It is important in software engineering because, with the help of this framework, teams are used to self-organize towards a particular goal.

Key principles of Scrum

Scrum consists of six types of principles which are as follows:

1. Empirical Process Control

This is the first principle under the scrum method, and it is divided into three sub principles such as:

1. Transparency: It is a kind of idea of universal visibility of the project and its progress will decrease the risks of misunderstandings which means that the person is managing the outcomes of the project and able to see the elements that affect those outcomes to success.
2. Inspection: The products that are being developed must be inspected in multiple stages of the project cycle which ensures that whatever is being developed it remains closely aligned to the original brief.
3. Adaption: It is a good methodology of product management that is sensitive to change, and scrum allows the team members to make the changes in between the sprints.

2. Self-Organization

Self-organization refers to when everyone is involved is empowered to work independently and this principle allows for greater buy in among all parties while making it easier to assess the individual contribution.

3. Time-Boxing

Time boxing refers to the scrum method which strict the time limits and enforced under various ways throughout the project. Some of the team members for slightly longer or shorter depends on product is being build.

4. Value Based Prioritization

The scrum team implementing the scrum method prioritize the overall value. Therefore, the development team try to create maximum business value in a short time and also delivering the high quality of product in that short time.

5. Iterative Development

The Iterative projects are broken down into small parts which means that a large project is being broken down into smaller parts. It allows the project stake holders to make changes in the midway through the projects.

6. Collaboration

Collaboration is different from the other principles as it relies on the collective input of different team members. It is final stage of scrum approach which is vital in between the team members and have a close relationship with the project stakeholders.

Scrum Roles and Responsibilities

Scrum teams is formed by three different roles which also highlights the skills and knowledge which needs to become a scrum master. Therefore, the three scrum roles are mentioned below:

1. Product Owner: Product owner is responsible for managing the demand of the companies its multiple stakeholders and partners. They are liable for better return in the investments.
2. Development Team: The development team are the group of individuals which collaborate together to create and execute the required production milestone. These teams are responsible to be self-organise and to make necessary choices to acquire the desired tasks and complete those tasks timely.
3. Scrum Master: Scrum masters are defined as the product team which implement scrum to generate a profitable value proposition. They are responsible for managing the product team, development team and also the company. They manage the work, plan and break down the given task between the team to acquire the desired outcomes.

Scrum Ceremonies

To make up the sprint there are five scrum ceremonies which are mentioned below:

1. Sprint Planning: Sprint Planning refers to the sprint by laying out the work which needs to be performed for the sprint. This plan is created by the collaborative work of the scrum team. The meetings of scrum planning occur at the starting of the sprint. During the sprint planning the scrum team commits the tasks which needs to be completed in the upcoming sprint.
2. Daily Scrum: The main purpose or objective of daily scrum is to inspect the progress of the sprint goal and to adapt the sprint backlog to adjust the upcoming planned work.
3. Sprint Review: The main objective of the sprint review is to inspect the outcome of the sprint and determine the future adaptation. The teams shows the results of them to the stakeholders and get the required feedback from them.
4. Sprint Retrospective: The main objective of sprint retrospective is to help the team to build the habit of continuous process of improvement. During the sprint retrospective the members of the team first suggest the topic for the discussion by writing their thought on reflection cards.
5. Backlog Refinement: It refers to the act of breaking down and further defining the product backlog items into the smaller items. It is the ongoing activity to add the details such as order, size and description.

Scrum Artifacts

There are three main agile scrum artifacts which are mentioned below:

1. Sprint Backlog: The list of everything which the team commits to achieve in a sprint is known as Sprint Backlog. If it is developed once nobody can add to the sprint backlog except the development team.
2. Product Backlog: The ordered list of every single thing which is needed in the product based on the product goal is known as product backlog. It is never complete, and it is always evolving.
3. Product Increments: Lastly at the end of each sprint the development team delivers a product increment which is potentially releasable.

Implement Scrum in Software Engineering Team

There are four steps which are used to implement scrum:

1. Systematically handle the product backlog.
2. Calculate the approx. time for the creation of product backlog.
3. Fully plan and complete the sprint.
4. Decide the budget on the Sprint.
5. Create a collaboration hub for the team.
6. Lastly Daily prepare a burndown chart.

Conclusion: Scrum in Software Engineering

Therefore, Scrum plays a major role in software engineering. Scrum mainly focuses on the teamwork, and it help the teams to deliver high quality products timely and effectively. In this article some of the important points are being covered such as key principles of scrum, its roles and responsibilities, Scrum ceremonies, scrum artifacts and so on.
