What is Agile Product Methodology?
Agile product methodology is a practice which promotes continuous development and testing of a software or product throughout the product development lifecycle. In this approach, both the development and testing activities remain concurrent.
Agile approach is known to be one of the most effective and simplest processes to turn a vision for a product into software solutions.

Agile Development Statistics:
85.9% of software developers around the world use Agile product methodology
Companies that use Agile approach for software development gain 60% more profits than those who don’t.
Agile success rates are more than 1.5x higher than those of Waterfall projects
According to Agile adoption statistics, plenty of Fortune 500 companies have adopted Agile

Agile Product Methodology Vs Waterfall Model
Waterfall Approach

  1. In the Waterfall approach, product development flows sequentially from one point to another; just like a Waterfall filling the next reservoir.
  2. Using Waterfall development means customers will see the product only at the end of the project
    Waterfall method is considered to be more secure because it is plan oriented.
  3. In the Waterfall method, errors are tested only when the whole product is ready. So, if changes are to be made, the product development has to start from the beginning.
  4. In the Waterfall method, product developers and testers work separately.
  5. All features of a software or product are delivered at once, at the end of the project, and after the long implementation phase.
    Agile Approach
  6. Agile method follows incremental approach to product development.
  7. Agile method promotes early launch of products. Customers get early and frequent chances to use the product. This helps product development teams in making decisions and do necessary changes to the product.
  8. Agile method is comparatively unstructured as compared to the Waterfall method.
  9. Agile allows product development teams to fix errors in the middle of the project. Within this method, teams continue to test products throughout the product life cycle and gain useful feedback from the customer.
    In the Agile method, both testers and product developers work together.
  10. In Agile product development mode, core features of a product are delivered to users, and new features are added over time.

Agile Methodology Advantages
Put simply, Agile is:
Iterative – involves regular rhythms of work
Incremental – requires product development teams to present product increment
Faster: It ensures faster reach to the market
Cost-Efficient: Agile reduces cost of development by allowing product development at the same time teams gather requirements and information
Responsive: product teams can respond immediately if there’s an unpredictable scenario and revamp the product accordingly.

How to Use Agile Methodology in Product Development
Agile teams follow these steps to create products:

  1. Project Initiation
  2. Create Backlogs
  3. Establish Sprints for Software Development
  4. Product Development
  5. Production and Deployment

Agile Product Development Processes (Framework)

  1. Scrum
  2. Kanban
  3. Extreme Programming (XP)

How to Manage Modern Software Projects: Waterfall vs. Agile

Always interesting to read a pro/con analysis between Waterfall & Agile methodologies.

Waterfall Pros

It is easy to understand and manage as stages are clearly defined.
Meticulous record keeping and documentation.
Client knows what to expect. Client will have an idea of the size, cost and timeline for the project. The client will have a definite idea of what their product will do in the end.
In the case of employee turnover, waterfall’s strong documentation allows for minimal project impact

Waterfall Cons
It often becomes rigid and resistant to change.
It relies heavily on initial requirements. However if these requirements are faulty in any manner, the project is doomed.
The whole product is only tested at the end. If errors are discovered late in the process, their existence may have affected the rest of the project.
The plan does not take into account a client’s evolving needs throughout the project cycle.

Agile Pros
It allows for changes to be made after the initial planning stage. It follows client’s requirements changes.
It is easier to add features that will keep the product up to date with the latest developments in the industry.
At the end of each sprint, project priorities are evaluated. This allows clients to add their feedback, so that they ultimately get the product they desire.
The testing at the end of each sprint ensures that the errors are caught in each cycle.

Agile Cons
This dynamic methodology is not suitable for processes that require a complex decision making of formal planning such as construction, manufacturing, military, health care system among others.
As the initial project does not have a definitive plan, the final product can be grossly different that what was initially intended.
