Agile and Scrum Development Methodology Techniques
Many organizations are adopting agile development methodology to fasten the software development lifecycle and release bug-free software.
Agile software development is a group of software methods based on iterative and incremental development. By doing continuous reviews & inspections we can easily identify gaps in the current agile process and we can add improvements for the next iterations.
scrum structures development in cycles of work called sprints. It works well for any complex/innovative projects. It ensures that the most valuable work has been completed when the project ends.
User Stories
User stories are nothing but user requirements throughout the project. A user story is nothing but what a user wants to do with a software, from a user perspective.
We should concentrate on few things before creating user stories. Those are listed below,
- User stories should be written in understandable language
- User story should focus on What to do, Who will do, Why should we implement this feature.
- Log all the key requirements
Scrum Roles
There are 3 roles in scrum methodology. They work together on daily basis to ensure is everything going smoothly or not.
- Product Owner
- Scrum Master
- Team
Product Owner
The Product Owner is responsible for communicating the vision of the product to the development team. He is the single point of contact to know about all product requirements. He will prioritize all the customer requirements. He will maintain the product backlog by keeping it up to date. The Product Owner will schedule the time for releasing completed work to customers and makes the final call as to whether implementations have the features and quality required for release.
Scrum Master
The Scrum Master acts as a bridge between the Product Owner and the team. Scrum Master work is to remove any impediments that are obstructing the team from achieving its sprint goals. Scrum Master needs to understand scrum well to train the entire team who are involved in the project. Scrum Master should approach all the team members to encourage their decision-making and problem-solving capabilities.
Team
The team is responsible for completing work. The team includes a mix of software engineers, architects, programmers, analysts, QA experts, testers, and UI designers.
Scrum Meetings
Below are the key areas to discuss in scrum meetings
- Backlog Refinement Meeting
- Sprint Planning Meeting
- Daily Scrum Meeting
- Sprint Review Meeting
- Sprint Retrospective Meeting
Product Backlog Refinement
Here we will split big items, analyze items, re-estimate, and re-prioritize, for future Sprints.
Sprint Planning Meeting
We will divide the sprint into two parts. One part is to define what to do and another part is to know how to do.
Daily Scrum Meeting
Update and coordination between the Team members
Sprint Review Meeting
Inspection and adoption related to the product increment of functionality
Sprint Retrospective Meeting
Inspection and adoption related to the process and environment
