THE LATEST MODEL IN SYSTEM DEVELOPMENT: AN OVERVIEW

The latest model in system development is the Agile Model. Agile model or methodology is a type of system development life cycle (SDLC) that prioritizes flexibility, customer satisfaction, and swift delivery of a functional system. Key features of the Agile model include iterative development, self-organizing teams, and customer collaboration.

The Agile model is a reaction to the constrAInts of more traditional system development models such as the Waterfall model. Unlike these older models, Agile does not treat system development as a linear, step-by-step process. Instead, it views system development as a series of iterative steps, where each step is a mini project in itself. This allows for greater flexibility, as changes can be made at any point in the development process without having to redo the entire system.

I. KEY FEATURES OF THE AGILE MODEL

Iterative Development

In the Agile model, system development is broken down into small, manageable chunks known as iterations or Sprints. Each iteration involves all the steps of the SDLC, including planning, analysis, design, coding, testing, and documentation. At the end of each iteration, a functional piece of software is produced, which can then be reviewed and tested by the customer. This allows for immediate feedback and makes it easier to make changes and corrections as the project progresses.

Self-Organizing Teams

Another key feature of the Agile model is the use of self-organizing teams. These are small, cross-functional teams that are given the autonomy to decide how to best accomplish their work. This fosters a sense of ownership and responsibility, and allows for faster decision-making and problem-solving.

Customer Collaboration

In the Agile model, the customer is an integral part of the development team. The customer is involved in every stage of the development process, from initial planning to final review and testing. This ensures that the final product meets the customer's needs and expectations, and reduces the risk of project failure.

II. ADVANTAGES OF THE AGILE MODEL

The Agile model offers several advantages over more traditional system development models. First and foremost, it allows for greater flexibility. Changes can be made at any stage of the development process, without having to redo the entire system. This makes the Agile model particularly suited to projects where the requirements are not fully known at the outset, or are likely to change over time.

The Agile model also promotes customer satisfaction. By involving the customer in every stage of the development process, it ensures that the final product meets the customer's needs and expectations. This not only reduces the risk of project failure, but also fosters a closer relationship between the development team and the customer.

Finally, the Agile model allows for faster delivery of a functional system. By breaking the project down into small, manageable chunks, it allows for incremental delivery of the system. This means that the customer can start using and benefiting from the system much earlier than would be possible with a more traditional model.

III. CHALLENGES AND LIMITATIONS OF THE AGILE MODEL

While the Agile model offers many advantages, it is not without its challenges and limitations. One of the main challenges is that it requires a high level of customer involvement. This can be difficult to achieve in practice, especially in large organizations where the customer may be a separate department or even a separate company.

Another challenge is that the Agile model requires a high level of trust and communication between the development team and the customer. This can be difficult to achieve in practice, especially in large organizations where the development team and the customer may be located in different parts of the world.

Finally, the Agile model requires a high level of discipline and self-organization from the development team. This can be difficult to achieve in practice, especially in teams that are used to more traditional, hierarchical ways of working.

IV. CONCLUSION

In conclusion, the Agile model is the latest model in system development. It offers many advantages over more traditional models, including greater flexibility, customer satisfaction, and faster delivery of a functional system. However, it also presents some challenges and limitations, including a high level of customer involvement, trust and communication, and discipline and self-organization. Despite these challenges, the Agile model is increasingly being adopted by organizations around the world, and is likely to continue to shape the future of system development.
