Agile Methodology is a newly evolved iterative incremental framework for managing complex work in faster manner which requires higher customer engagement and interaction. It puts more emphasis on the rapid software development with lower documentation, lower planning and lower rework effort. The rapid development process ensures early bug detection and higher customer engagement to have better deliverables at lower cost.
Requires more interaction with the client, client reviews all the changes in period manner
In the Agile process, testing happens almost in parallel and a requirement is divided into a number of iterations
The requirement is divided into modules which can be developed independent of other modules
The development done is immediately tested so that new impacts of any new development are clearly known to the client
Easier to incorporate the changes with much ease and lesser time
Lower documentation required to start the design and development in Agile methodology
Provides better quality product in lesser timeline
This methodology is highly successful in projects having frequently changing requirements
Main features of Agile Methods
Adaptive Software Development (ASD)
Dynamic System Development Method (DSDM)
Scrum is an agile process that allows us to focus on delivering the highest business value in the shortest time. It allows us to rapidly and repeatedly inspect actual working software after a short interval time. During the regular inspection, anyone can see real working software and decide to release it as is or continue to enhance it for next iteration.
Benefits – Team
Tasks are clearly defined which helps team members to perform well
Team members understand the expectations on themselves
Sense of team ownership
Lot of co-operation between team members and hence they learn things quickly
Self sustaining team
Better team work
No hierarchy leads to better co-operation and team spirit.
Agile Methodology is used when?
The requirements were not clear during the initial stage
The Client wants to track the development processes since beginning to check whether all the requirements were meeting the business requirements
Project is spread across different Geographical locations
More active customer involvement was needed as the system is heavily customized
The client wants SME participation at every level
The client wants to have visibility on the progress of the project and timely identify any risks/issues that block progress.
The client wants to evaluate technical options before implementing changes and identify best option (both in terms of cost and business value to end users).
Key benefits to clients using Agile Methodology
Agile Methodology helps the client to track the development of the project at every step. Client checks the working prototype early which reduces the rework effort
Helps client to understand the requirement completely during the development phase through higher level of engagement.
Complex business requirement changes are handled easily
Helps to achieve faster completion of the project
Helps absorb late changes to requirements, as was the case in reality. This ensures timely decisions, against late changes.
With a wall visible to everyone and daily stand-ups, agile ensures risks/blockers are identified and addressed quickly.
Agile helps gradual implementation of the changes, instead of peaking towards cut-over
