Agile and Custom Development: Iterative Approaches to Software Creation

The process of developing software is dynamic and complex, requiring flexibility and adaptability to meet evolving requirements and user needs. Two methodologies that embrace this flexibility are Agile and custom development. In this blog, we will explore how Agile and custom development approaches align with iterative methods to create software that is tailored to specific requirements, responsive to change, and optimized for user satisfaction.

Agile Development

Agile is a software development methodology that emphasizes flexibility, collaboration, and customer-centric development. It is founded on several key principles:

  1. Iterative Development: Agile breaks the software development process into small, manageable iterations, typically referred to as sprints. Each sprint focuses on delivering specific features or improvements.
  2. Customer Collaboration: Agile places a strong emphasis on engaging customers and stakeholders throughout the development process to gather feedback and ensure that the software aligns with their needs.
  3. Adaptability to Change: Agile embraces change and welcomes evolving requirements. It allows for adjustments and refinements to be made in response to new insights or changing circumstances.
  4. Cross-Functional Teams: Agile teams are typically cross-functional, consisting of individuals with a variety of skills and expertise, which fosters collaboration and efficiency.
  5. Working Software: The primary measure of progress in Agile is “working software.” Each iteration should produce a functional, tested, and potentially shippable piece of software.

Custom Development

Custom development, on the other hand, centers on creating software solutions tailored to the unique requirements and specifications of a specific project or client. It involves:

  1. Detailed Analysis: Custom development begins with a thorough analysis of the client’s needs, business processes, and objectives. This analysis informs the creation of a custom software solution.
  2. Bespoke Solutions: The development process focuses on building a one-of-a-kind software solution that precisely meets the client’s needs and aligns with their unique business practices.
  3. Scalability: Custom solutions are designed with scalability in mind, allowing them to grow and evolve as the client’s requirements change.
  4. Integration: Custom software can be seamlessly integrated with existing systems and technologies, optimizing workflow and data management.

Iterative Approaches

Agile and custom development both embrace iterative approaches:

  1. Agile Iterations: Agile methodologies break development into short iterations, typically lasting two to four weeks. These iterations result in functional, incremental improvements to the software, allowing for rapid adaptation and feedback.
  2. Custom Development Iterations: In custom development, the iterative approach focuses on building specific components or modules of the custom solution, testing them, and incorporating client feedback before moving on to the next phase. This incremental process ensures that the final product aligns precisely with client requirements.

Advantages of Agile and Custom Development

  1. Customer-Centric Approach: Both Agile and custom development prioritize customer collaboration, ensuring that the software solution precisely meets user needs.
  2. Adaptability: Iterative approaches in Agile and custom development accommodate changing requirements, helping to avoid costly project delays and overruns.
  3. Quality Assurance: Frequent testing and feedback in iterations lead to improved software quality and reliability.
  4. Efficiency: Incremental development allows for early delivery of functional features, reducing time to market.
  5. Scalability: Custom development inherently supports scalability as software is built to grow with the client’s needs.

Conclusion

Agile and custom development methodologies, while distinct, share the common thread of iterative approaches that promote flexibility, user-centric design, and adaptability to change. By embracing these iterative methods, software development teams can create solutions that not only meet specific client requirements but also respond to evolving user needs, ultimately delivering more valuable and effective software products.

The 12 Principles Behind the Agile Methodology

The need for Agile Methodology became apparent due to the enormous time lag between business requirements and the delivered technology. Due to this a lot of projects were being cancelled and customers & technology managers needed a solution for these challenges.

One of the prominent causes for these challenges was due to the lack of communication between client, project manager and stakeholders. The final product did not meet the client’s expectations.

The Agile methodology for development is the perfect resolution for these issues as it involves the customers at every stage of the project.

What is Agile?

The core of the Agile methodology is rooted around best practices that enable collaborative environments amongst diverse business units to ensure continuous learning, improvement, production & growth.

Agile model is a culmination of iterative and incremental project cycles focussed on process adaptability and customer satisfaction. By breaking the product into small incremental builds, Agile focussed development ensures rapid delivery of the project.

The main belief behind Agile is that every project needs to be handled differently and all the development methods need to be customised to best suit individual project requirements. All Agile tasks are divided into small time frames to deliver specific features in an iteration.

Each iteration involves cross-functional team coordination in various areas like −

  • Planning & Requirement Analysis
  • Coding
  • Design
  • Unit Testing and
  • Acceptance Testing.

In order to effectively implement the agile methodology in your organisation, you need to follow its 12 principles that support teams in driving the project with agility. 

1: Prioritise Customer satisfaction with Continuous & consistent Delivery

Customers love to stay on top of things when their product is being developed. Which is providing them with regular updates and demonstrating phases of the working product greatly improves their confidence and keeps them satisfied? This also ensures all the detrimental bugs do not stay unnoticed until the end of the project.

2: Welcoming Change throughout the development process

Getting a major change at the end of the project can be somewhat disparaging. However, the agile methodology is designed to not handle late changes but welcome them. Due to the incremental iterations, the probability of a major change in the project’s late stages is reduced quite a bit.  

3: Deliver Working phase of project Frequently 

Deliver working product frequently, from a couple of weeks to a couple of months, preferably keep a shorter timescale. The faster you deliver an incremental product, the faster you’ll receive the feedback and identify a wrong turn or a miscommunication from the client.  

4: All stakeholders and Developers Should collaborate Daily

Better decision making and faster resolutions are achieved when everyone involved in the project works together. It not only brings the whole team on the same page but since everyone discusses what they are working on, valuable insights can be derived in terms of project improvement.  

5: Motivated Individuals deliver better projects 

Provide your team with a supportive environment and trust them to get the job done. The agile methodology encourages self-organised teams that are capable of managing themselves and the work. Micromanagement is not necessary for the Agile model.

6: Face To Face Communication

The most effective method of relaying information within a team is a face-to-face conversation. Most of the time the development teams are often distributed and not there at the same time. Which is why every effort must be made to communicate often and increase the use of technical communication tools.

7 Working model Is a Primary Measure of Success

It is crucial for agile project teams to focus on developing a working prototype to show their progress.  Irrespective of the number of bugs that have been fixed or the hours you have put in the product development, the only thing that counts is a working product.

8: Agile Methodology Promotes Sustainable Development

The stakeholders & developers should be able to maintain a constant and consistent pace. Setting the right pace is necessary for the success of an agile project. Working overtime without consideration of the quality is highly detrimental for the project. Constant pace also improves forecasting capabilities.

9: Focus on Technical Excellence and Good Design

These are two of the most important elements that play their part in a project’s success. While applying Agile methodology, you do not have to spend time refining the code. With every iteration, the code automatically improves so you do not have to worry about it. Using scrum tools can further amplify the speed of the process without compromising on the quality of the final product.

10: Simplicity is Essential

When it comes to managing projects through agile methodology, you should keep things simple and reduce the time required in the documentation. Prioritise the basic functionalities before another add ons which won’t have an impact on the overall project.

11: Self Organising Teams

The best architectures and designs emerge from the efforts of self-organizing teams. Well organised teams that are cross-functional as well as confident in their execution.  A project manager should encourage this sort of culture and plan to reduce dependency as much as possible

12: Reflects on How to Become More Effectively

At frequent intervals, the team should reflect on how to become more effective and tune their behaviour accordingly. The agile methodology defines several practices such as Retrospective. This is done after each iteration and makes sure that the mistakes of the past don’t get repeated.

Conclusion:

The main intent of the Agile methodology is to align development with business requirements, and the success of Agile is apparent. All Agile projects are customer-centric and encourage their feedback and participation. Due to these features, Agile has grown to be a model for product development.
