What is Agile Scrum Methodology?

An Effective Method Of Developing Products

Scrum is an agile software development approach that is built on iterative and incremental procedures. The scrum project management methodology allows software development companies to prioritize critical work and divide it into manageable chunks. Scrum is an agile framework that is adaptive, rapid, creative, and successful at delivering value to the client. Scrum’s primary goal is to serve the customer’s requirements by fostering open communication, collective accountability, and continuous improvement.

The development process begins with what we need to design and develop according to priority.

History of Scrum

Scrum goes back to 1986 when Hirotaka Takeuchi and Ikujiro Nonaka experimented with different product development techniques and failed to reach the optimal product development strategy. Thereafter, they discover scrum-based product development and then they published an article in the Harvard Business Review (HBR) titled “The New Product Development Game”. The article discusses how firms like Honda, Canon, and Fuji-Xerox create new products utilizing a flexible and team-based methodology. In addition, This strategy highlights the critical role of self-organized teams.

In 1993, Jeff Sutherland and his team at Easel Corporation developed the Agile Scrum methodology to use in software development methodologies with the help of object-oriented development, empirical process control, iterative and incremental development.

Process of Scrum Methodology

Scrum methodology focuses on a specified set of activities and responsibilities that must be part of the process. Moreover, it’s a highly adaptable technique that promotes adopting the agile principles within a framework agreed by product team members.

Scrum implements short, periodic chunks called sprints, which typically last between two and four weeks. They are very helpful in tracking feedback. The procedure begins with a list of project objectives/requirements. Then, the project’s client prioritizes these goals based on a trade-off between their value and cost; this is how we define iterations and subsequent deliverables.

Roles of Agile Scrum

The Scrum team aims to produce high-quality software. Therefore, the Scrum project owner concentrates on identifying what qualities the product must have to develop (what to create, what not to create, and in what sequence) and overcoming any obstacles that may obstruct the development team’s tasks.

The Scrum Team consists of the following individuals:

Scrum Roles
Scrum Roles

Scrum Master: Scrum Master is the person in charge of leading the team and ensuring they follow the methodology’s rules and practices. He/She handle the project’s obstacles and collaborate with the Product Owner to optimize ROI. In addition, the Scrum Master is responsible for maintaining Scrum up to date and providing guidance, counseling, and coaching to the teams if needed.

Product Owner: The product owner (PO) represents the product’s stakeholders and customers. They concentrate on the business side of things and are in charge of the project’s return on investment. In addition, they communicate the project’s vision to the team and confirm the benefits in stories added to the Product Backlog, and prioritized regularly.

Scrum Team Members: A group of people or professionals with the necessary technical competence who work together to create the project and complete the stories they commit to at the beginning of each sprint.

Scrum Events

Each Scrum event allows some part of the process, product, progress, or relationships to be modified.

Sprint: A sprint is the fundamental work unit of a Scrum team. This is the significant difference between Scrum and other agile development methodologies.

Sprint Planning: Sprint Planning aims to specify what we can accomplish during the Sprint and how we will achieve it. This discussion occurs at the start of each Sprint and defines how we will approach the project based on the Product Backlog phases and timelines. Each Sprint consists of several different characteristics.

Daily Scrum: The Daily Scrum’s purpose is to analyze progress and trends through the Sprint’s conclusion, coordinating activities and developing a strategy for the next 24 hours. It is a short gathering that occurs every day during the Sprint timeframe. We address three separate questions: What did I do yesterday? How am I going to spend my day? What assistance do I require? In addition, the Scrum Master should attempt to resolve any issues or roadblocks that occur.

Sprint Review: The sprint review’s objective is to demonstrate what work has been achieved in relation to the product backlog for future delivery. After the sprint is over, there should be a noticeable and demonstrable improvement in the product to offer to the customer.

Sprint Retrospective: The team examines the sprint’s accomplished objectives, noting both the good and the negative to avoid repeating the errors. This phase makes changes to the development process. The sprint retrospective identifies potential process changes and develops a strategy for implementing them in the next Sprint.

Scrum Artifacts

Product Backlog: It is a set of user stories for a scrum product. The product owner is responsible for creating and maintaining the product backlog. It is prioritized by the product owner, and anybody may contribute to it with the product owner’s consent.

Release Backlog: A release is a period during which we accomplish specific iterations. The product owner and scrum master collaborate to determine which stories should be prioritized for release. The release backlog contains stories which schedule to finish in a certain release.

Sprint Backlog: The sprint backlog is a collection of user stories that must be fulfilled within the sprint. During the sprint backlog phase, the team signs up for tasks independently. The team owns and controls it with the remaining work calculated daily.

Conclusion:

Why use Agile Scrum Methodology?

Scrum is a clear and straightforward framework. The principles, artifacts, events, and roles are very simple to comprehend. Its approach eliminates uncertainties in the development phase while allowing enterprises to add their input.

It is useful for challenging projects because of its arrangement of complicated activities into user stories. Additionally, the clearly defined responsibilities and events provide accountability and shared responsibility throughout the software development cycle. Finally, rapid releases keep the team engaged and users satisfied by allowing them to see progress in a short period.

Scrum may take some time to grasp fully, mainly if the development team uses waterfall methodology. In addition, smaller iterations, daily scrum meetings, sprint reviews, and appointing a scrum master may provide a difficult culture transition for a new team.

However, the long-term advantages surpass the early learning curve significantly. In addition, Scrum’s success in building complex software products across a range of industries makes it an attractive framework for your firm to adopt.

The Agile Testing Model

Agile testing is a model of testing that focuses on the standards and requirements of agile software development. Agile testing starts at the outset of the project. Moreover, the agile model of testing is not sequential but is continuous.

What is the Agile testing Process?

The Agile Test Process includes various forms of testing during each iteration. Thus, It includes test environments, test details, testing tools, and evaluation results. Therefore, an agile model results in creating and modifying a test plan for each release.

By looking at the case study, one of the finance companies reinvented its custom-built storefront and home office systems in response to changing state and federal regulatory compliance requirements. The IT and PMO teams were more focused on operational maintenance than on the challenges of system development. This resulted in an unmanageable workload and years-long schedule delays. The project’s employees had been impacted by staff and technology churn, requiring repeated restarts and integration difficulties.
However, after the introduction of the agile model, they have changed the overall workflow of the system which resulted in very good results.
Through the use of agile methods, job completion rates increased 400% over time, while rejection rates for work submitted for QA testing decreased from 30% to 5% over six months.

The typical agile testing model includes the following:

  • Conduct research on the project scope
  • Conduct testing on the improved functionality
  • Load/Performance analysis
  • Framework analysis
  • Development of risk mitigation strategy
  • Resource Allocation
  • Deadlines and Achievements 

What is Agile Testing Lifecycle?

During Agile testing, the lifecycle consists of four phases.

  1.   Iteration 0 – Initiation of a project

Firstly Iteration 0 is where you finish the initial setup tasks. Secondly, This job includes recruiting people for various tasks. Among them perform testing, implementation, software testing, and resource management. The following steps describe this stage.

  • Development of a company business plan
  • Define the project’s specifications and scope
  • Define main requirements and use case studies
  • Critical Risk Assessment
  • Initial project planning and budget estimate

 2.  Development Iteration

The agile project managers provide high-quality applications throughout the development iterations. These iterations should meet the demands of the stakeholders. Following are the steps to accomplish it:

  • Cooperation
  • Analyzing and planning
  • Assuring accuracy
  • Regular application deployment
  1.   Release

The objective is to deploy your system in development efficiently. The operations at this stage include training users, service staff, and operational personnel.

Additionally, the last phase of the agile approach involves acceptance testing In repetition, you will track down and confirm whether a problem arises.

  1.   Production

The software developer has to ensure that the apps succeed post-launch. What strategies work in one company can be different in another. And then, maintaining the system’s effectiveness is an ongoing objective.

What are the Quadrants?

Agile Testing Quadrants Most importantly, the agile test quadrants split the whole process into four quadrants.

Agile testing quadrants
Agile Testing Quadrants

Tests can be conducted for the following purposes:

Support Programming: 

These types of tests are used by software engineers to determine the best code to write. This is required to carry out a certain device action. For instance, there should be constant testing of the modified device’s behavior during the development process.

Critique Product: 

Firstly critical quality tests are performed on the finished product to detect defects.

To decide the experiments should be done, you must first determine if the research is:

  • Business faces 
  • Technology Face-to-face

Business Facing:

An examination is an assessment of a corporation based on how it responds to questions posed by business. Market researchers are aware of this and will participate in them to clarify the machine’s behavior in real-time.

Technology Facing: 

A review consists of looking at answers to questions in the area of technology. Furthermore, programming problems stem from several layers of technological concerns.

The agile assessment quadrants assist teams in defining, planning, and conducting required training.

Quadrant Q1: This quadrant specifies Unit testing. Moreover, Automation is a possibility for tests of this type.

Quadrant Q2: Functional testing is needed for this quadrant. Manual and automated tests are also appropriate methods.

Quadrant Q3: This quadrant necessitates the use of unit monitoring and user acceptance testing. However, there are manual assessments.

Quadrant Q4 – This Quadrant needs Output and load tests. This quadrant includes stress testing, scalability testing, and maintainability testing. We can use Special tools, in addition to automated testing.

By integrating all of the quadrants, it is possible to explain What-Testing-When as follows:

Quadrants specification
Agile Testing Quadrants Specification
Value problems for agile development of applications

a) Since reporting is a low priority in agile growth, there are more opportunities for mistakes.

b) In addition, Technologies may be deployed quickly, reducing the time taken for review teams to determine if existing features meet the requirements and resolve market problems.

c) Testers perform the functions of a developer.

d) The testing process’s intervals are incredibly brief.

(e) Less time spent on test plans

f) They must follow a strict schedule for regression testing.

g) Transforming their position from quality gatekeeper to quality associate.

h) Requirement adjustments and improvements are an integral part of an agile approach, which is the primary QA difficulty.

Conclusion

In software testing, the agile method necessitates testing during the software development life cycle. However, when it becomes functional, it necessitates improved stakeholder involvement and code testing. The code must be safe to submit to systematic review. To ensure that all issues have been fixed and checked, Testers should perform thorough regression testing. Finally, communication between teams is the primary factor that contributes to success during an agile training process.
