Fundamental Software Development Best Practices

Software development is a complex process that requires adherence to a set of best practices to ensure successful outcomes. As a software engineer or developer, it is imperative to understand and implement these practices from the very start of any software project.

This is because effective software development practices can help you to deliver high-quality code within tight deadlines, lower risks, and enhance the overall development process. In this article, we'll explore 15 fundamental software development best practices that every developer should know, including coding standards, version control, testing, documentation, and refactoring, among others. By following these practices, you'll be better equipped to develop software that meets the requirements of your clients and delivers maximum value to your development team.

What is Software Architecture?

"Software architecture" refers to the approach taken in conceptualizing and developing the framework of a software project. In order to design a system, decisions must be made regarding how its various components will communicate with each other, how information will flow between nodes, and what resources - human and technological - will be made available. Incorporating best practices, such as utilizing version control, unit testing, and code refactoring, among others, leads to a more maintainable, scalable, and efficient software design. Additionally, a style guide can facilitate developer collaboration by promoting consistency and clarity within the codebase. Ultimately, the goal of software architecture is to develop a clear blueprint for a software project that can be followed to ensure a stable, efficient, and easily updatable and maintainable final product.

Why is writing software code without software testing an issue?

Writing software code without software testing can be a significant problem. Testing ensures that the software will perform the functions as expected, and the code meets the desired standards. Good testing practices help ensure that the software is reliable, efficient and meets the requirements.

Without testing, the software may contain bugs or errors that can cause serious issues down the road, and it can also harm the code quality. Writing code quickly and correctly is important, but keeping your code simple and not writing code you don’t need is equally important. Testing ensures that existing code is working correctly and integration with other software will work as intended. Therefore, developers should always incorporate testing into their software development process to ensure they’re achieving the best possible outcome.

Here are 15 best practice software development

1. Have a Well-Defined Software Development Process

Having a well-defined development process is crucial in maximizing the efficiency of your software development team. By establishing and adhering to robust processes, teams can avoid common errors, making it easier to detect and address issues in the application or code. Structuring development around a simple model such as Waterfall, Agile, Lean, or Scrum enables teams to efficiently plan, test, and deploy software.

Every one of these versions, however, comes with its own set of benefits and drawbacks that must be taken into account. Agile, Lean, and Scrum are iterative methods that place a premium on collaboration and adaptability, as opposed to the more conventional Waterfall method, which emphasises a linear progression of development. One method might be better suited than the others, depending on the requirements of the undertaking.

Regardless of which model a team chooses, having well-defined processes in place allows for consistent and efficient development, reducing the risk of errors and delays. It also fosters better communication and collaboration among team members, enabling them to work together more effectively towards the common goal of delivering quality software.

2. Effective communication

Communication is a vital component of software development and a key factor in the success of software products. To ensure quality and meet project requirements, a common best practice is to conduct code reviews, where multiple members of a development team review the codebase for potential issues or areas for improvement.

During these reviews, clear communication between team members is essential. This ensures that everyone is on the same page and that the software is of high quality. Moreover, effective communication between software developers and stakeholders, such as project managers or clients, is crucial to ensuring that the software meets business needs and stays on track to meet project timelines. By fostering open and transparent communication channels, software development teams can identify and address issues early on, resulting in a better final product.

However, it's worth noting that effective communication requires more than just reviewing code and having regular meetings. It involves active listening, articulating ideas clearly, and being receptive to feedback. Additionally, utilizing tools like project management software and messaging apps can facilitate efficient communication and collaboration. Ultimately, a culture of open communication and teamwork is vital to delivering quality software products on time and within budget.

3. Collaborate On-Site and Off-Site

When software development teams collaborate both on-site and off-site, a variety of perspectives and ideas can be shared and discussed. This cross-functional collaboration promotes a greater understanding of complex tasks like design, development, coding, and testing while also saving time by working with fewer resources. To achieve effective collaboration, it's important to strike a balance between off-site communication through virtual platforms and in-person discussions at all stages of development. Virtual collaboration tools like messaging apps, video conferencing, and project management software can facilitate seamless communication and collaboration regardless of location. However, in-person discussions are equally important as they allow team members to build relationships, establish trust, and provide valuable feedback in real-time.

Effective collaboration can also help to improve the quality of the final product. By bringing together diverse perspectives and skill sets, teams can identify and address issues more efficiently and innovate more effectively. Furthermore, collaboration can foster a sense of ownership and accountability among team members, which can lead to increased motivation and a better overall team dynamic.

Ultimately, cross-functional collaboration is a key ingredient in successful software development, promoting greater understanding, innovation, and efficiency. By leveraging both virtual and in-person communication channels, teams can work together to deliver high-quality products that meet project requirements and exceed expectations.

4 - Divide the developments into phases or deliverables.

Once a scope has been drafted, it is convenient to separate the project into sections or phases that allow the client to see results during development. If a project lasts 10 months, we cannot have the client without seeing anything during the 10 months of development, we must show the results, which will also help us to make certain adjustments and not reach the end of the project and the client makes us change more than half of the developments. Dividing the project into phases, sprints or sections will allow us to set goals in short periods and show the results.

5. Establish Source Control System

Having a dependable source control system in place is a crucial component of successful software development. These systems are designed to monitor changes made to software code, making it simple to determine who made modifications and when. This enables improved versioning and increases the transparency of the development process. With a source control system in place, teams can easily manage and monitor the deployment of different versions of software artefacts, which is essential for identifying discrepancies and recovering deleted files as needed.

Another important advantage of source control systems is their capacity to manage software code modifications efficiently. This enables teams to deploy new features while ensuring that the extant code is bug-free and intact. With a dependable source control system, teams can make changes and enhancements to software in a controlled and organised manner, allowing for seamless collaboration. This ultimately results in a higher quality final product and a more efficient development process.

6 - Documentation

Documentation is a crucial aspect of software development that ensures that software engineers maintain best practices in writing code. A software engineer must understand the importance of documenting their software code for future references as well as maintaining the readability of their code.

As a software engineer, you're gonna need to write code that is easy to understand and code that is simple to modify or update. Writing reusable code will also be an added advantage, as it saves time and effort when recycled in future projects. The goal is to make your code as readable as possible, and you can only achieve this through documenting your code from the start. Maintaining excellent documentation is an essential best practice in software development that cannot be overemphasized.

7 - DRY: Don't repeat yourself.

DRY stands for "Don't Repeat Yourself," and it's an important principle in software development. Essentially, it means that you shouldn't write code you don't need to. This is an important best practice, as it helps to avoid duplication and potential errors. When you write code, it's important to keep it simple and clean. This makes it easier to read and understand, as well as easier to maintain in the long run.

Code review is an important process for ensuring that you're following these best practices, and that the code you write is of a high quality. As a developer, it's important to always strive to write code that is efficient and effective, while keeping in mind the principles of DRY. This can help ensure that your software project is successful and that you are able to deliver high-quality results to your clients or users.

8 . Continuous improvement

Continuous improvement is important to ensure that software remains relevant and effective over time. The development team must continue to improve the software and address issues and opportunities for improvement.

Implementation of best practices can help ensure software is delivered on time and according to customer specifications. This can improve customer satisfaction and increase the likelihood that the customer will do business with the company again.

9.Automate Tasks with Scripts Wherever Possible

Automating tasks through the use of scripts is a highly effective software development practice for producing quality, sophisticated code. By keeping complex portions of a project in scripts, teams can ensure that any modifications made to it are applied consistently throughout the project, avoiding redundant and inconsistent code copied and pasted into separate parts of the program.

This approach also simplifies the automation testing process, which can significantly reduce the overall build time. Automation is essential to achieving efficient development, as it leads to fewer errors, faster iteration times, and ultimately, higher quality products. With the aid of automation, teams can focus on more significant aspects of software development, such as feature development, innovation, and optimization, rather than menial tasks that can be accomplished through scripting.

10. Quality Assurance at Every Step of the Way

No matter the size of the software development project, implementing a QA strategy from the beginning is essential for producing high-quality products. A consistent and comprehensive QA strategy can help detect errors early on, which saves time and money in the long run. Effective QA testing ensures that the software is free of bugs and that it meets project requirements. Additionally, regular testing can help identify potential issues with new features or products, allowing developers to make improvements before release. By prioritizing QA from the outset, software development teams can increase efficiency, reduce costs, and improve overall user satisfaction.

11. Apply frequent refactoring

Software refactoring is the process of modifying or restructuring existing code to make it easier to understand, easier to maintain, and easier to change. Refactoring will allow you to add flexibility to your system to meet changing requirements or adapt to future code changes.

It involves understanding the existing code and requirements, restructuring the code for easier maintenance, making changes to the existing one to achieve the required flexibility, validating the change against the requirements, and finally putting the change into production.

12. Reduction of technical debt

Technical debt is used in the software industry to cover debt due to bugs, legacy code, or missing documentation. It is usually used interchangeably with design debt or code debt.

When development teams take “workarounds” (shortcuts) to speed up the delivery of a feature or project, they take on technical debt, which then needs to be refactored. Technical debt is the result of prioritizing fast delivery over perfect code.

13. Continuous Integration / Continuous Deployment

The agile software development approach requires each member of your team to integrate and implement software changes into production. And this happens at least twice a day, every day. So, if you have this need for frequent production shifts, you need to make sure that every member of your team can quickly track and fix the issues that release has caused. These practices cover the entire software development life cycle , from coding/code review to deployment/testing.

Personally, I don't suggest you do this frequently, but sometimes, due to various circumstances, it is unavoidable, so you and your team should take it into account so that you can react effectively to problems due to rapid releases to production.

14. DevOps.

DevOps is a set of software development and operations best practices that have emerged in recent years in the field to help teams deliver projects in a highly agile manner by merging software development and operations. DevOps aims to deliver software applications faster by introducing automation to almost everything.

DevOps is a framework and mindset that encourages a flexible approach to the product development process, considering the requirements, risks, and constraints of the various stakeholders involved, customer requirements, and working to meet expectations. It requires a very high level of commitment from all participants in the project, including the client or users. That is why it is frequent that in our culture it does not have the expected results since the project or work plan is not attended to with sufficient rigor.

15. Monitoring and Registration

For Agile teams, maintaining continuous delivery is essential but can be challenging without proper monitoring and recording systems in place. It's important to be able to detect and identify bugs in a controlled environment and take prompt corrective action to keep the development team on track.

To achieve this, observability is crucial, and investing in a centralized monitoring and logging system such as Elastic Stack, AWS CloudWatch, or Azure Monitor can be a great asset. These systems allow for the easy tracking of performance metrics, system logs, and other key data points, providing teams with valuable insights into their software development processes. With a solid monitoring and logging system in place, Agile teams can ensure that they are delivering high-quality products consistently and efficiently.

In conclusion, developing software is a complicated process that needs to follow a set of best practises to be successful. Effective software development practises help deliver high-quality code on tight deadlines, reduce risks, and improve the overall development process. Best practises like using version control, unit testing, and code rewriting, among others, lead to a software design that is easier to manage, can be scaled up, and works better. For software development to go well, there needs to be good communication, teamwork both on-site and off-site, and a clearly stated process. By following these best practices, software engineers and developers can make software that meets the needs of their clients and gives their development team as much value as possible.
