How to Choose the Right Software Development Methodologies for Your Next Project?

Software development methodologies are vital for managing the challenges of software development, such as changing requirements and deadlines. Various methodologies, including Agile, Scrum and Spiral, are available, but selecting the right one is crucial as not all are suitable for every type of software. By choosing a suitable methodology and adhering to it, developers can ensure efficient work, effective communication and proper documentation, resulting in the timely delivery of high-quality software.

What are software development methodologies?

Software development methodologies consist of a series of processes and procedures implemented during the software development lifecycle, with the aim of benefiting both the development team and the clients.

An in-depth look at software development methodologies

To deliver high-quality products, custom software development companies leverage various methodologies such as Agile, Spiral, Scrum, Extreme Programming, Rational Unified Process and Big Bang.

Agile methodology

Agile methodology is an iterative approach to software development that prioritizes continuous planning, communication and collaboration between teams and clients. Other frameworks like Scaled Agile Framework (SAFe), Large-Scale Scrum (LeSS) and Scrum of Scrums (SoS) can customize Agile practices to meet the needs of a specific organization or project.

Phases

The software development process typically consists of several key phases:

Concept Phase

Inception Phase

Iteration Phase

Quality Assurance

Software Release

Scrum methodology

The Scrum methodology follows an iterative development approach, where team members break down large tasks into smaller ones and work on them using sprints. This incremental approach accelerates development and adds value to complex projects. Moreover, the Scrum framework enables developers to incorporate conventional system development methodologies with flexible Agile practices.

Phases

The Scrum process involves several phases:

Product Backlog

Sprint Backlog

Daily Scrum Meeting

Product Increment

DevOps

DevOps, a term that gained popularity in the IT industry between 2007 and 2008, refers to a set of advanced tools, practices and process automation philosophies that combine IT operations with software development. By providing a framework for building, testing and releasing software rapidly. DevOps ensures improved outcomes and enables the continuous delivery of products.

Phases

The DevOps process involves several phases:

Continuous Integration

Continuous Testing

Continuous Development

Continuous Deployment

Continuous Monitoring

Waterfall Model

Winston Royce introduced the Waterfall Model in 1970 through his research paper. This sequential and linear approach emphasizes the systematic progression of steps in the development process. In the Waterfall Model, each stage must be fully completed before the next phase can begin.

Phases

The software development process typically includes the following phases:

Requirements analysis

Design

Implementation

Unit testing

Integration and system testing

Operation and maintenance

Iterative

The iterative or incremental development model breaks the entire software development process into smaller segments, enabling teams to gradually improve the evolving versions until the entire system is ready. This model helps identify issues and make necessary improvements within a limited budget in the initial stages of the software development life cycle.

Phases

The Iterative process includes the following phases:

Planning

Analysis

Implementation

Evaluation

Spiral Model

A spiral model is a hybrid approach that blends iterative and waterfall models. It is risk-driven, with each phase beginning with a predetermined goal and ending with a client review. The development team adds new features in a continuous spiral, increasing in scope with each iteration until deployment.

Phases

The spiral model typically includes the following phases:

Planning

Risk Analysis

Engineering

Evaluation

V Model

The V Model is a commonly used software development methodology that incorporates testing at each stage of the project, allowing for the timely completion of the project. However, each step must be completed before moving to the next, ensuring that the project stays on track and on target.

Phases

The V Model includes the following phases:

Unit Testing

Integration Testing

System Testing

User Acceptance Testing

Big Bang

The Big Bang model is a simplistic approach to software development that is suitable for small projects but may lead to quality issues in larger projects due to the absence of in-depth planning and testing. Additionally, changes in requirements can cause significant delays, making it difficult to manage the project as a whole.

**Unlike other SDLC models, the Big Bang model doesn’t have specific phases.**

Feature-Driven Development (FDD) Model

Feature-driven development (FDD) is a software model created in 1997 by Jeff De Luca and Peter Coad for a Singaporean bank project. They built it in 15 months with 50 professionals. The FDD team comprises a project manager, chief programmer, chief architect, development manager, class owner and domain expert. In the first phase, an overall model of the system is created to provide a high-level view of the features to be developed.

Phases

The Feature-Driven Development (FDD) Model includes the following phases:

Build a Feature List

Plan by Feature

Design by Feature

Build by Feature

Test by Feature

Integrate Features

Launch the System

Prototype Methodology

The prototype methodology involves creating an initial version of the software system that may have limited functionality, reliability and efficiency compared to the final product. However, it is a valuable tool as it allows the client to visualize and better understand the expected outcome of the final software product, which may not have been clear in the initial stages of the project.

Phases

The Prototype Methodology includes the following phases:

Requirement collection and analysis

Faster design

Create a prototype

Initial user evaluation

Redefining prototype

Implementation of product

Timely maintenance

Rapid Application Development Methodology

The Rapid Application Development (RAD) methodology emphasizes quick customer feedback and rapid prototyping over prolonged development and testing cycles. This approach enables developers to make frequent iterations and updates to software efficiently, without starting from scratch each time. Moreover, RAD ensures that the outcome is high-quality and meets the end user’s requirements.

Phases

The Prototype Methodology includes the following phases:

Goal Planning

Prototype Design

Rapid Development

Production

Lean Development

The primary objective of the lean software development methodology is to minimize waste, improve efficiency and deliver the necessary features for the product. This approach involves releasing an initial software version developed by software engineers.

Principles

Here are some fundamental principles and practices often associated with lean development:

Define value from the customer’s perspective.

Map the value stream and identify waste.

Create flow by eliminating waste and optimizing the value stream.

Establish pull by letting customer demand drive development.

Pursue perfection by continuously improving the process.

Summary

Choosing the right software development methodology for your project is crucial and depends on various factors such as project scope, budget, resources, and time frame. It’s essential to analyze the pros and cons of each methodology and consider the necessary tools and expertise required.

How much time will it be and what will it cost? Let’s look at a few points about what kind of handrails we have.

[symphony-software]

Methodologies Of Software Development Life Cycle

Methodologies for software application development have evolved greatly over time. Most of these methodologies have become obsolete and irrelevant. At Symphony Software, we use dominant SDLC frameworks, including Agile and DevOps to ensure that the final product fits end users .

Whether you’re a software development company or someone who needs customized software, it’s worth looking at SDLC methodologies chronically.

Here we go:

Old SDLC Methodologies

Waterfall - The First SDLC Methodology (the 1970s to 90s)

This linear-sequential model goes through all SDLC phases without overlapping. The next phase can begin only if the previous one is complete. This method tended to be lengthy and costly. So, technology leaders started seeking more flexible alternatives.

Prototyping Model

This software engineer method involves creating low-cost prototypes. Prospective users use the prototype and provide early feedback to project managers. Accordingly, prototypes are converted into the final product as per the client’s requirements.

Iterative Model

An early precursor to Agile, the iterative model involves a development team creating the first version of the software based on initial requirements. Then, more iterations are created as additional requirements are identified.  Each iteration goes through all SDLC phases, and cycles are repeated until completion.

Spiral Model

This model involves identifying risks before recommending an approach that combines different SDLC methodologies, including Waterfall and Iterative. The one-size-fits-all approach doesn't work here.

V-Shaped Model

Similar to the waterfall model, the next stage in the V-shaped framework begins only when the previous one is finished. However, it stands unique in that testing takes place at every development stage. Software testers verify whether every requirement has been met and validate the system for users and stakeholders.

Modern SDLC Methodologies

Lean Model

The Lean model for software development focuses on eliminating waste, making decisions as late as possible, and delivering results faster. Teams work to find ways to reduce waste at every step. At its core, the model empowers the entire project team in decision-making.  

Agile Model

The agile model combines an incremental and iterative approach. The software is released, tested, and improved at each iteration. Surprisingly, the agile model encourages fast failure because it's believed that failing fast and early helps discover minor issues before they turn major.

Scrum Model

The Scrum model is a popular Agile framework that emphasizes close and continuous collaboration. It involves special development cycles known as Sprints.

A Scrum Master manages and improves all processes and helps teams abide by Agile values for maximized productivity. Scrum Masters also ensure that the whole process and progress are transparent to concerned stakeholders.

DevOps

DevOps is basically a hybrid of lean and agile. In this model, both developers and operation teams collaborate to speed up and innovate the software development process. It involves continuous feedback, improvements, and the automation of manual processes.

Which one is the best?

Of course, modern SDLC methodologies have added advantages. But to make an informed decision, it’s important to dig deeper into these models. So, don't forget to read our next blog, "What is Waterfall and its pros & cons."

A distribution waterfall is a method in which capital gains of the fund are distributed between or among investors or partners, typically between limited partners (LPs) and general partners (GPs). The profits earned are distributed according to the cascading structure of sequential tiers with reference to waterfall.  Basically, when the first tier's allocation requirement is satisfied, the excess funds will be subjected to the next tier's requirement.
