What is an Agile Methodology?

Agile processes in which teams deliver the final outcome of the project by dividing it into small segments and achieving these small segments in continuous successful iterations.

In this methodology, client and project management team continuously work together by being in touch with each other and keep one another updated about the customer’s requirement.

In this way, customer’s expectations are clarified to the project team effectively.

The agile methodology begins with the explanation of the client’s expectation, requirement, what problems need to be solved by this project, etc.

Once this is done the project management team divide and distribute each segment of a project to respective teams.

All of these is done through continuous communications from both sides.

Definition:- Agile Methodology aims to the development of the project in continuous iteration by breaking a project into small segments. 

Agile has six different sub methodology which follows the same rule within agile, therefore sometimes these methodologies are also known as frameworks of agile. These agile methodologies contain.

  1. Scrum Methodology
  2. Lean Software Development Methodology
  3. Crystal Methodology
  4. Dynamic Software Development Method (DSDM)
  5. Extreme Programming
  6. Feature Driven Development (FDD)

Steps Involved in Agile Methodology.

  1. Meeting between client and project team.
  2. Datagram and initial requirements.
  3. Distribution and division of the project into smaller segments and team respectively.
  4. Continuous releases of segments into production.
  5. Providing ongoing support in production.
  6. Termination or end of the support on successful completion.

 

  1. Meeting between client and project team.

In this step, the project development team management of the company and client involved comes forward and holds the meeting.

The aim of this meeting is to deliver a clear picture of user requirements, his expectations, problems to be focused and many more.

  1. Datagram and initial requirements.

This step also includes meeting but in between management of the company and project development team.

The aim of the meeting is to build a datagram for monitoring the iteration and completion of the project. This datagram is visible to all ends including client, management and project team.

  1. Distribution and division of the project into segments.

Here a project leader divides the workflow of the project into segments and assigns each segment to each team within the project development team.

The main aim of this step is to deliver the result in an optimized manner be it time resources or money, also all the teams are expected to work in a synchronized manner.

  1. Continuous releases of segments into production.

Once the project begins it is expected by the client that he will receive a small segment of the working project in iterations at regular intervals of time.

The main aim of this step is to complete the full project by braking it into sub-groups and focusing each sub-groups with utmost attention that no error or fault is found after final production.

  1. Providing ongoing support in production.

After regular intervals of releases in production, it is monitored and examined by the client and by that time project building team starts working on the next segments.

If any further changes required by a client he/she contacts the management team and management team updates the project team, this team then encounters the changes needed by client resolves it and again pushes it into production.  

This providing of support between client and project team remains intact even after final production of the project, for a certain amount of time-based on contract.

  1. Termination or end of the support on successful completion.

Once there no changes needed by the client and the contract between both of them comes to an end, the final step takes place.

In this step, the project team provides every minute detail of the project including how did they complete their work, source code, resources they took etc.

The aim of this step is to provide client everything related to project and makes him/her independent to do further changes, from here there are no formal contract between client and project team and all the relations related to project terminates here.

Advantages of Agile Methodology.

  • Improved Quality
  • Focus on business value
  • Focus on users
  • Stakeholders Engagement
  • Transparency
  • Early and Predictable Delivery
  • Predictable Costs and Schedule
  • Allows for change

What is Scrum?

what-is-a-scrum

In the traditional way of deploying any project, the project needs to first build completely and then it needs to be launch and by the time of launching, a project may run out of schedule, may get outdated in the market, over budget and many more.

Therefore a new method of working was introduced to know as Scrum.

Scrum is not a unique methodology but rather it is an agile framework for managing a process. Scrum is used by 12 million users around the globe.

Scrum as it is based on agile methodology, therefore the project is broken into pieces, and these broken pieces are called sprints.

But for a time being let’s refer sprints as segments. So this is how your project might look into Scrum architecture.

Working of Scrum.

Once the project is conveyed to the scrum master and project team they then divide the project into smaller segments called sprints. Now each sprint consists of four elements plan, build, test, review.

what-is-a-agile

Now the main working of scrum is based on these sprints. What happens is that when a project is broken into small segments or say sprints, the working of sprints is defined by sprint architecture refer above figure.

First, the team makes a plan to achieve current sprints, then they build requirements of sprints, then they test it and then finally review that if anything more is left to add or not.

On successful completion of this sprints, it is sent into production and then next sprint is undertaken in order to complete. In this way, the whole project is broken down into sprints and is completed.

 

 

Three Key role-playing persons in Scrum.

  1. Product Owner

This is the main person who has the idea of a final product and user needs. This individual is the owner of final product and it is the main bridge between customer, stakeholders and project team.

  1. Scrum Master

This is the main head of the scrum process and project team, this individual keeps the integrity of the project. It this individual to whom all the reports are made about the project before the product owner.

  1. Project Team

This is the actual building block of scrum methodology, it is them for whom all these methods are implemented. The project team may consist of developer, testing, article writer and many. Sometimes the job of tester might be done by the developer and vice versa, but the main aim of this team is to deliver the project.

Documents Used In Scrum.

  1. Product Backlog

In this documentation process the expectations of customers are taken beforehand. Customers are asked what all their expectations are there, what problems they are facing, any further development and many more. The main primary focus in this documentation is customer needs and their requirement because all these works revolve around the customer.

  1. Sprint Backlog

In this documentation the feedbacks of customer is mentioned about their current experience on final product, but this document only consists the most important and prior feedback.

E.g. feedback that is same for n number of customers.

  1. Burndown Chart

This document consists a statistical analysis or report of the current project, but the main focus is to provide a statistical data about Sprint backlog, that is how efficiently and how early the team resolved the most prior feedback of customers.

Meeting in Scrum.

  1. Sprint Planning

As we already told a Sprint is a segment (a small section of the final project). Here product owner holds a meeting with scrum master and project team in order to update them with his idea, time schedule, budget, customer point of view, market costs, expectations from the final product and many more. Overall the aim of this meeting is to convey the idea about final project to scrum master and project team.

  1. Daily Scrum

In these types of meetings, the scrum master invites project team to take update about current sprints. These meetings are held after every completion of each sprint.

  1. Sprint Review

Here again meeting is held between product owner, scrum master and project team. This meeting is held after the final deployment of the project. Customers review, feedback, expectations are discussed in this meetings, if there are no changes to be made in ongoing deployment then the project team showcase their portfolio for further projects and development. This is the last meeting of the scrum process.

Difference Between Scrum And Agile(scrum vs agile).

Agile Scrum
Agile is a methodology to do any project. Scrum is not a methodology, but a framework of agile methodology.
There is a project leader in agile methodology. There is a scrum leader.

 

This is a rigid method of doing any project, and there is less room for changes. This is a flexible way working project, and last moment changes are always welcomed.
Project is built with the project leader and there is a centralized leadership in agile. All the team works cooperatively, and there is no centralized leadership.
Delivery and update of the software is on regular intervals. On completion on each sprint, next sprint is taken into effect.
