Certainly! Here’s a detailed, rewritten English version of the article you provided about Agile in software development:
What is Agile in Software Development?
Agile software development is a methodology designed to help teams work faster and more efficiently by breaking projects into smaller, manageable parts that can be worked on simultaneously.

Using Agile, teams continuously evaluate requirements and results to implement changes quickly and effectively.
Agile emphasizes teamwork and customer satisfaction. It focuses on consistently creating products that truly meet market needs. Project roadmaps become clearer and more flexible, allowing adjustments based on customer feedback. This adaptability helps Agile teams stay aligned with rapidly changing market trends.
Agile emerged as a response to the more rigid Waterfall methodology. In Waterfall, the development process is linear, requiring teams to complete each project phase before moving to the next—often causing longer project timelines.
In contrast, Agile enables teams to work in parallel on different phases, speeding up development and increasing flexibility.
The Agile Software Development Process
According to Spiceworks, Agile development consists of six main stages:
1. Concept
At this initial phase, the product owner defines the project scope. When handling multiple projects, priorities are set to focus on the most important tasks.
During concept development, the product owner discusses requirements with clients and estimates project timelines and budgets. Detailed analysis helps determine if the project is feasible.
2. Inception
Once the concept is clear, the next step is building the development team. The product owner assesses team availability and selects members best suited for the project, also ensuring they have access to necessary resources.
After assembling the team, design work begins—creating user interface mockups and UML diagrams. Project architecture is also established at this stage.
These designs are then shared with stakeholders for feedback and suggestions.
3. Iteration (Development)
This phase often lasts the longest as most development work happens here. Developers collaborate with UX designers to integrate product requirements and customer feedback, translating designs into functional code.
4. Release
When development completes, the product nears release. Before launch, the quality assurance team rigorously tests the software to ensure it functions correctly and is bug-free. Any issues found must be promptly fixed by developers.
The team also prepares user tutorials during this phase.
Once bugs are resolved and users trained, the final product iteration is deployed to production.
5. Maintenance
After release, the development team moves into maintenance, providing ongoing support to keep the system running smoothly and addressing any bugs that arise.
They may also offer additional user training and gather feedback to plan future updates and features.
6. Retirement
Products enter retirement for two main reasons: either they are replaced by newer versions, or the system becomes obsolete.
At this stage, the development team informs users about the discontinuation and helps migrate them to new systems if available.
Finally, all remaining end-of-life tasks are completed, and support for the old application is phased out.
Benefits of Using Agile
As highlighted by Decipher Zone, Agile offers several advantages:
- Better control: Agile provides greater project oversight through transparency, quality control, and continuous feedback integration. Stakeholders can monitor quality with daily reporting tools throughout the project lifecycle.
- Reduced risk: Frequent feedback enables early identification of errors and helps create effective risk mitigation strategies.
- Increased flexibility: Agile divides projects into smaller parts, allowing quick implementation of changes. This contrasts with other methods where changes are costly and time-consuming.
- Continuous improvement: Agile encourages ongoing enhancements, fostering collaboration and idea exchange among team members to improve skills and outcomes.
- Higher product quality: Repeated cycles of review and refinement help maintain high standards and deliver superior final products.
- Customer satisfaction: Multiple stakeholder inputs throughout development ensure the product better aligns with customer needs, leading to increased satisfaction.
Agile vs. Waterfall: A Comparison Example
Waterfall Approach
A company’s software project under Waterfall might follow these steps:
- 5 weeks gathering and analyzing requirements
- 6.5 weeks designing basic wireframes
- 13 weeks coding and initial testing
- 6.5 weeks system testing
- Remaining time for user acceptance testing
Total duration: approximately 31 weeks (8 months).
Agile Approach
Using Agile, the same project is divided into eight iterations, each lasting 4 weeks.
- Business and development teams prioritize key features collaboratively.
- After each iteration, the team delivers a working product version.
- They review goals and decide on changes or additional features for the next iteration.
- This cycle repeats, allowing the final product to be ready in about 4 weeks, with continuous improvement along the way.
Frequently Asked Questions (FAQ)
Why do many companies choose Agile for software development?
Agile provides a structured yet flexible framework that helps manage projects efficiently. It documents all requirements, ensuring smooth progress.
Compared to Waterfall, Agile better accommodates market changes and evolving customer demands, reducing project failure risk.
Adopting Agile allows companies to keep pace with shifting trends and deliver products aligned with user needs.
Additional benefits include improved team management via tools, enhanced communication, and breaking complex tasks into manageable parts.
