Traditional Software Development and Agile Software Development are the ways of the designing and developing system software. Both are important types of the software designing.
Traditional Software Development
Traditional Software Development is the software development process used to design and develop simple software. It is used when the security and many other factors of the software are not much important. It is used by freshers to develop the software. It consists of five phases:
1. Requirements analysis
2. Design
3. Implementation
4. Coding and Testing
5. Maintenance
Phases of Software Development
Advantages of Traditional Software Development
- Well-Established Methodology: Traditional software development follows a well-established methodology that is widely understood and documented.
- Clear Requirements: Traditional software development relies on clear and detailed requirements, which helps to ensure that the final product meets the customer’s needs.
- Structured Approach: Traditional software development follows a structured approach, with clear phases and milestones, which helps to ensure that the project stays on track.
- Proven Success: Traditional software development has a proven track record of success and is widely used in many industries.
- Quality Control: Traditional software development typically includes extensive testing and quality control processes, which helps to ensure that the final product is of high quality.
Disadvantages of Traditional Software Development
- Slow Process: Traditional software development can be a slow process, with lengthy planning and design phases.
- Lack of Flexibility: Traditional software development can be inflexible, with changes to requirements or design difficult to implement once development has begun.
- High Cost: Traditional software development can be expensive, particularly if the project is large or complex.
- Limited Customer Involvement: Traditional software development often limits customer involvement to the planning and design phases, which can result in a product that does not fully meet their needs.
- Limited Innovation: Traditional software development can be conservative and risk-averse, which can limit innovation and the development of new ideas.
Agile Software Development
Agile Software Development is the software development process used to design complicated software. It is used when the software is quite sensitive and complicated. It is used when security is much more important. It is used by professionals to develop the software. It consists of three phases:
1. Planning
2. Requirement Analysis
3. Designing
4. Implementation
5. Testing
6. Deployment
Agile Software Development
Advantages of Agile Sogtware Development
- Flexibility: Agile software development is highly flexible and can easily adapt to changes in requirements, design, and scope.
- Customer Involvement: Agile software development encourages frequent customer involvement, which can result in a final product that better meets their needs.
- Continuous Delivery: Agile software development typically includes continuous delivery, which means that working software is delivered to the customer on a regular basis.
- Collaboration: Agile software development emphasizes collaboration between team members, which can lead to better communication and problem-solving.
- Early and Frequent Testing: Agile software development includes early and frequent testing, which can help to catch issues and bugs early in the development process.
Disadvantages of Agile Software Development
- Lack of Predictability: Agile software development can be less predictable than traditional methods, with less certainty about the final product and its delivery schedule.
- Limited Documentation: Agile software development often relies less on documentation, which can make it difficult to track changes and understand the system architecture.
- Time and Resource Constraints: Agile software development requires a significant commitment of time and resources from all team members.
- Less Emphasis on Planning: Agile software development often places less emphasis on detailed planning, which can result in scope creep and delays.
- Resistance to Change: Agile software development requires a significant cultural shift and may be difficult for some team members and organizations to adopt.
Difference Between Traditional and Agile Software Development
|
Traditional Software Development |
Agile Software Development |
|---|---|
|
It is used to develop simple software. |
It is used to develop complicated software. |
|
In this methodology, testing is done once the development phase is completed. |
In this methodology, testing and development processes are performed concurrently. |
|
It follows a linear organizational expectation structure. |
It follows an iterative organizational structure. |
|
It provides less security. |
It provides high security. |
|
Client involvement is less as compared to Agile development. |
Client involvement is high as compared to traditional software development. |
|
It provides less functionality in the software. |
It provides all the functionality needed by the users. |
|
It supports a fixed development model. |
It supports a changeable development model. |
|
It is used by freshers. |
It is used by professionals. |
|
Development cost is less using this methodology. |
Development cost is high using this methodology. |
|
It majorly consists of five phases. |
It consists of only three phases. |
|
It is less used by software development firms. |
It is normally used by software development firms. |
|
The expectation is favored in the traditional model. |
Adaptability is favored in the agile methodology. |
|
Traditional software development approaches are formal in terms of communication with customers. |
Agile software development methodologies are casual. In other words, customers who work with companies that utilize Agile software development approaches are more likely to interact with them than customers who work with companies that use traditional software development methodology. |
|
For starters, typical software development approaches employ a predictive approach. There is full specification and prediction of the software development processes because the product is produced through rigorous and explicit planning. Changes are not permitted in this technique because the time and cost of project development are fixed. |
Here, a flexible approach is used as the software development approaches are founded on the notion of continual design improvement and testing relies on team and client feedback. |
