Leading Custom Software Development Company
Custom software development is the process of creating software for a specific customer or organisation. It entails gathering requirements from the customer, analysing their needs, and designing a custom solution to meet their exact specifications.

Introduction to SDLC: 

The Software Development Life Cycle (SDLC), a structured procedure, is used to plan, create, and test high-quality software. It provides a well-structured flow of phases that help organizations produce software that meets customer expectations, is well-tested, and ready for production use. SDLC ensures that software is developed with the highest quality, lowest cost, and shortest time possible.

SDLC encompasses various stages, including requirement analysis, planning, software design, development, testing, and deployment. The program must fulfill the required goals and requirements, and each stage is essential to the entire development process.

 

Stages of SDLC: 

Planning and Requirement Analysis

The first stage of SDLC is planning and requirement analysis. This stage involves gathering input from stakeholders, including customers, salespeople, industry experts, and programmers. Finding the needs for the new software and comprehending the system's advantages and disadvantages are the objectives. Planning for quality assurance and risk assessment is also done during this stage.

 

Defining Requirements: 

The next stage is to precisely define and record the product requirements after the requirement analysis is finished. A program Requirement Specification (SRS) is a document that specifies all of the features and functionalities that the program must have. The SRS document acts as a guide for the development team and guarantees that everyone is aware of the project requirements.

Designing the Product Architecture: 

The design stage involves transforming the software specifications into a design plan called the Design Document Specification (DDS). This plan is reviewed by stakeholders, and the best design approach is selected based on factors like risk assessment, product robustness, and budget constraints. The DDS outlines the architecture of the software, including its modules and data flow representation.

Building or Developing the Product:

Once the design is finalized, the actual development of the software begins. Coding standards are followed as developers create the code in programming languages like C++, Java, or Python. The development stage is essential because it establishes the framework for the finished product. To guarantee that the development process is efficient and seamless, it is crucial to follow the agreed-upon blueprint and coding standards.

Testing the Product:

The testing stage is an integral part of SDLC and is usually involved in every stage of the process. During this stage, the software is tested for defects and deficiencies. To make sure that the programs satisfy the specified criteria, many testing approaches are utilized, including functional testing, performance testing, and security testing. Defects and issues identified during testing are fixed, and the software is retested until it meets the quality standards.

Deployment in the Market and Maintenance:

The programme is introduced to the market after it has undergone extensive testing and been given the all-clear. The deployment stage may involve releasing the software in stages or testing environments before the final release. This allows stakeholders to provide feedback and catch any final mistakes or issues before the software is made available to the public. After deployment, the software requires continuous maintenance, including monitoring for security vulnerabilities and updating with patches and updates as necessary.

SDLC Models:

There are several SDLC models that organizations can choose from based on their specific needs and project requirements. Let's take a look at some of the most popular SDLC models.

  • Waterfall Model:

The Waterfall Model is the oldest and most straightforward SDLC model. It adopts a sequential methodology, finishing one phase before moving on to the next. For projects with clear criteria and little customer participation, this model is suitable. However, if adjustments are needed later in the development process, it lacks flexibility and might cause delays.

  • Iterative Model:

The Iterative Model emphasizes repetition and rapid development. It involves creating a version of the software quickly and then testing and improving it through successive iterations. This model allows for flexibility and early customer feedback, making it suitable for projects with evolving requirements.

  • Spiral Model:

The Spiral Model combines elements of both the Waterfall and Iterative models. It follows a spiral-shaped approach, where each iteration involves planning, design, development, and testing. This methodology allows for risk assessment and mitigation at every level, making it ideal for large and complicated projects.

  • Agile Model:

Software development is done iteratively and with the client in mind using the agile model. It emphasizes collaboration, adaptability, and continuous improvement. Agile teams work in short sprints, delivering working software and gathering feedback from stakeholders. This model is ideal for projects with rapidly changing requirements and a high degree of customer involvement.

  • V-Model:

The V-Model is an extension of the Waterfall Model. It emphasizes testing at each stage of development, ensuring that defects are caught early in the process. This model is beneficial for projects with a strong focus on quality and testing.

  • Big Bang Model:

The Big Bang Model is a high-risk approach where most resources are allocated to development. It is suitable for small projects with well-defined requirements and limited complexity. However, this model lacks a thorough requirements definition stage and can lead to potential issues later in the development process.

Integration of DevSecOps into SDLC: 

In today's quickly evolving digital environment, security is a key aspect of software development. The main goal of DevSecOps, a branch of DevOps, is to incorporate security procedures throughout the whole SDLC. At each level of the development process, DevSecOps makes sure that security evaluations are carried out, such as code reviews, architecture analyses, and penetration tests. Software can withstand potential attacks and vulnerabilities by implementing security from the earliest design stage to the final delivery.

  • SDLC and Security:

Security is crucial to the process of developing software. SDLC addresses security concerns by incorporating security practices at various stages. Let's explore how security is addressed in each stage of SDLC.

  • Planning and Requirement Analysis: 

During the planning and requirement analysis stage, security requirements and potential security risks are identified. Security design principles and best practices are considered to mitigate potential threats and vulnerabilities. This stage sets the foundation for a secure software development process.

  •  Architectural Design:

The architectural design stage focuses on identifying potential risks and implementing security measures. Threat modeling, access control, encryption mechanisms, and architecture risk analysis are performed to ensure that the software is designed with security in mind.

  • Software Development and Testing:

Security controls are put into place and code reviews are carried out during the software development and testing stage to make sure security requirements are being followed. Penetration testing is one type of security vulnerability test that is used to find and fix potential security flaws.

  • Deployment:

Security precautions are put in place during the deployment phase to make sure the program is installed safely in the production environment. To shield the software from potential dangers, firewalls, access controls, and other security settings are established.

  • Maintenance:

Security continues to be a concern even after the software is deployed. Continuous monitoring is essential to detect and address security vulnerabilities. Regular software updates and patches are applied to keep the software secure.

The Best SDLC Model for Custom ERP Software Development: 

When it comes to custom ERP software development, selecting the right SDLC model is crucial for success. The Agile Model is often considered the best fit for ERP software development due to its flexibility, adaptability, and focus on customer satisfaction. ERP systems typically have evolving requirements and require continuous improvement, making the Agile Model an ideal choice. It allows for frequent iterations, enabling the development team to incorporate changes and feedback from stakeholders throughout the development process.

Benefits of SDLC:
