Agile Software Development emphasizes the creation of business value with right sized, just-enough, just-in-time processes, cross-functional teams shipping a product increment after each iteration and a high degree of customer & developer interaction.
Some Traditional Software Development methods consider processes and documentation as the main measure of business value. In Agile methods software requirements are prioritized based on business value, and the measure of Business Value is Return on Investment.
Here are 5 ways Agile Software development processes and practices help to develop High Quality Software at the same time maximizing Return on Investment that is the highest interest to stakeholders.
Quick respond to change
The value of software cannot be predicted beforehand, it can only be validated in the market place. The incremental delivery of software allows business people to embrace market changes and opportunities that arise during the project implementation. Agile ceremonies like Stand Ups and Iteration planning help teams change and adopt to new things systematically while allowing stakeholders to reprioritize features quickly, make changes between the iterations that will decrease costs and fit to market faster than their competitors.
Using short iterations to deliver releasable features
Our days technology evolves and changes at a very fast pace which limits the up-front planning possibilities for business people. Agile offers incremental delivery of product using iteration cycles ( mini releases) which are the subset of the final product. These iterations include activities such as requirements analysis, design, development and testing. Iterations are pre-determined and time boxed and the scope of the work being delivered in each iteration fits the iteration length and not vice-versa.
Frequent feedbacks from end users
Early feedbacks help to mitigate risks of the project as early as possible. 21 century customers have unpredictable needs and must be involved in decision making throughout the project. Short iterations make it possible to gather feedback early and refine the requirements for the next iteration. Agile methods quickly adopt to customer needs and plan requirements based on the observations of the market it operates in.
Time to market focus
One of the main principles of Agile is speed. Statistics show that most features that are built by software developers are not being used. That’s why it is better to build less and work on the speed. In addition, building less avoids complex applications with numerous lines of codes that are difficult to maintain. By delivering piece of functions after each iteration, teams have opportunity to remove impediments and inspect & adapt after each iteration. It is cost sensitive to fix defects over time because there is context switch, communication and bugs being built on existing bugs Often releases enable stakeholders to generate revenue earlier and also make customers wait for your next releases
Build quality in is one of the 7 principles of Lean Software Development which is practiced in Agile Methods like Scrum and Extreme Programming. Agile Software Development Methodology offers processes like Test-Driven Development and Continuous Integration to ensure the delivery of high quality software.
Test-driven development (TTD) is a practice where unit tests of features are written prior to writing codes for these features. It makes certain what the functions have to do and that the code actually does that. TTD reduces the technical risks that the software implementation won’t match what it is being asked for and market risks as it helps to identify the needs of marketplace.
In traditional methods programmers may work on the code from hours to weeks and as a result generate a lot of defects and bugs. Continuous Integration is a development practice that requires developers to integrate code into a shared repository several times a day. Each integration is verified by an automated build to detect integration errors as quickly as possible. The benefits of continuous integration is that it minimizes costs because it takes less time to find and fix problems, increases visibility and communication, reduces time spend on debugging and allows to deliver software more rapidly.
