No longer than you think, the project you were working on was near completion is when suddenly your boss expects you to relook at the project with fresh requirements and new angle.

That instantly threw you off your comfortable state to something bewildering. You ask yourself, why me? well, that’s not going to help much. This is the reality!

With the rapidly changing world that we live in, an agile solution is today’s new. One has to think with an open mind and, be flexible to introduce new elements when fresh requirements come about.

This is commonly seen across businesses nowadays, where managers are tossing new ideas at clients or customers to win their hearts, and going with the flow.

Questioning change is no use, but asking why to adopt Agile methodology is a good start. What is Agile methodology? and how can this help counter an array of last minute changes in the project planning and execution, covers the subject matter of this blog. Let’s dive straight into it to understand how it really works.

An overview: Agile Methodology

With Agile methodology, the project team can dream to successfully deliver the project in time, and ensure all modalities are met as required by the client. Isn’t that great?

  • Agile Methodology has important principles which include customer satisfaction, co-operation, and communication, working software importance, embracing change to name a few.
  • Agile methods break-up complex tasks into the small incremental task.
  • The iteration involves a team with cross-functional skills. Planning and requirements analysis, designing and coding, unit testing, and acceptance testing are done by the same team.
  • Once iteration is implemented, a working product is presented to the client. This reduces overall risk and allows the project to adapt the changes easily.

As above, is a graphical representation of Agile methodology in ‘Sprint’ project.

What is Scrum?

Scrum is an Agile Framework for completing a Complex project. There are many frameworks in Agile out of which Scrum is one of the most important frameworks.

  • Scrum is an adaptive, iterative, fast and flexible methodology.
  • Scrum is designed to quickly deliver notable value during a project.
  • It will ensure effective communication and creates a framework of combined liability and ongoing progress. The Scrum team discuss ways to develop processes as they move ahead into succeeding Sprints.

This framework consists of three roles – Product Owner, Team and Scrum Master. Know their respective responsibilities, next:

scrum

Product Owner

Product Owner plays a key role in Scrum, Agile Methodology. S/he is typically a person who communicates with the customer to understand the requirement. S/he is responsible for the overall project vision and target.

S/he participates actively in Sprint Planning and Sprint Review meetings; determines release plan and communicates same to the upper management and also with the customer.

Team

In Scrum, it is recommended to have 7 to 9 people in a team. Importantly, If the team remains same for the tenure of the release, then it can deliver the work easily without any deviations.

The team members earn the maximum advantage if they belong to the same place, but Scrum will also work well if the team is diversified/globalized.

Scrum Master

A Scrum Master oversees that Scrum in agile methodology is appropriately performed by the team. She/he does everything in his/her capacity to help the team achieve targets successfully, clearing all bottlenecks or issues incase they arise during the process.

Scrum Master ensures that team is following Scrum to its core values and principles.

What is Product Backlog

If you are planning to work on Agile, you should aware of user stories. Here, the Business Analyst breaks-down the requirements into smaller components called as ‘user stories’.

In Product Backlog, you will find a list of things, of value to the business, for the team to produce. Each gets a rank in the order of priority.

The product owner can add, change, remove and reorder items in the product backlog. These modifications can be made only before starting of a Sprint Planning Meeting.

What happens in Sprint Planning?

A Sprint Planning meeting is the first activity inside a Sprint. In this, we consider only high priority ‘user stories’ in a Backlog in particular Sprint.

A Sprint may fluctuate between one and six weeks. During the Sprint, a Scrum Master coordinates Daily Standup Meetings and, the Scrum Team discusses progress. Toward the end of the Sprint, there is a Sprint Review Meeting during which the Product Owner and concerned business people are provided a demonstration of the Deliverable.

V Model or Agile, Which one is the best?

V model or Agile, it can be better understood and compared basis on the following attributes:

1. Productivity

2. Product Quality

3. Customer Satisfaction

4. Return on investment (ROI)

Productivity

Productivity comes from people who are working on the technology method, irrespective of the technology or framework they use. If we are to compare the V-Model with Agile, the Agile model has slightly better results.

Case Scenario:

Let’s say, a quality team is testing ten features of a project and, the team is in the middle of verifying the implementation. The team has verified five features and the remaining features are pending, but while doing so the team faces slight changes in requirements which may affect all the features.

In V-Model, there will be a need to update all phases of SDLC which means the testing team will be spending 50% more time in retesting due to the changes.

In the Agile framework, The team is testing throughout the cycle and constantly making adjustments to the code. Meaning, productivity loss is next to none. In fact, it will ease the burden on the team in adopting changes more easily.

Product Quality

Software development takes place in incremental, rapid cycles. This results in small incremental releases with each release building on earlier functionality. QA team performs granular testing on each release to ensure software quality.

Customer Satisfaction

Delivering products to market more quickly with every release. The clients get access to the product at an initial stage during the SDLC life cycle. The idea is to keep customers involved and engaged throughout projects.

Return on investment (ROI)

Software is developed to enhance business performance. Focusing on business value is really the key when a client determines the feature set and lays out the priority for a required software. The development team must understand this well, and accordingly deliver the software with more important features first, to match business goals.

Return on investment

Advantages of Agile Methodology according to following parameters:

Parameters

Agile Model

An approach of this methodology

This methodology is very flexible and adjustable and can adapt to the project needs.

Measurement of Success

The success of the project in an Agile model is measured by the Business value delivered.

Ability to adapt the changes

In Agile model the changes are accepted and adapted as per the project needs.

Revenue

In Agile method the return on investment is early in the project cycle.

Benefits Agile Methodology

Key Takeaways

Change is bound to take place, new requirements will kick-in as and when. That’s really when Agile Methodology helps software developers to match speed and quality with minimum wastage of time, money and efforts.

In Agile, the endeavour should be to proactively and constantly communicate with the client, in order to stay updated on new requirements and also get quick feedback. Agile methodology is a time-tested, now widely-used, practice to counter unprecedented dynamism in any growing business.

Time-bound pressures of delivering high-quality software are met using Agile methods.
