Successful software development is a complex process. Over the years, software engineers and developers have refined software development practices to improve the consistency of outcome. However, there is always a room for improvement.
When developing software for applications, time is just one factor; there are human resources, financial resources, and commitment that go into software development.
Statistics show that more than 80% of software development projects do not bring about the expected result because of deployment and management issues.
That means a lot of wasted resources.
You can’t choose to take a risk.
Over the years, software development has transitioned into a sophisticated and comprehensive system of complicated software design and deployment.
The sophistication in the process can be heavily owed to the software development practices that have been improved over a number of decades.
Software development is always growing, improving and transitioning, which essentially means that there is never the best way but always a better way to do things.
Your dedicated efforts in software development can go down the drain if they are not backed by proven techniques that can bring about successful results.
Top Software Development Best Practices
Remember that there are a lot of things that go into making software a success, so doing one thing right and neglecting another is a recipe for disaster.
So, we have divided the best practices for successful software development in three primary groups with each group equally important for the successful deployment of software design and development.
Code Development and Testing Practices
- Do not waste time in writing codes that you do not need. You may write a code for future use but the chances are that you will have to rewrite it to make it relevant to the future specifications.
- Only test the code that you write not the infrastructure, libraries or frameworks.
- While designing API, always design a simple case with minimum configuration first.
- When conducting unit test make sure that all code paths are tested with 100% coverage.
- Only write necessary code and keep it defensive; anything can go wrong.
- Logic is easy to test if it is side-effect-free. Always break the logic into varied and separate functions rather than compiling in a mixed logic.
- Use built-in types to speed up the writing process. Python built-in standard types can save you time than the custom objects.
- Avoid object constructors; they are hard to test. Try not to put the code in __init__.py.
- Fix or delete the tests that intermittently fail. These tests can wear down the value of the testing.
- Use up-to-date Software testing tools.
Agile Software Development Best Practices
If you haven’t adopted agile development process yet then it’s time to revisit your project management strategy.
Successful software development teams rely on the following best practices for agile development:
- Software deployment is a complicated task. But it can be simple and easy to manage if you have a proper system in place. Always use an app deployment checklist to make sure you can complete the critical tasks on time.
- Use continuous integration server to test the code in real time with other developers. This will ensure that data integration works on all platforms and developers’ workstations for a consistent output. This also helps with continuous testing that allows you to test with other developers and improve accordingly.
- Always choose deployment automation software to detect errors. Never deploy new versions of the software manually. This will only increase the chances of human error.
- The best and simplest way of automating deployment is to use the specific scripts within a specific environment.
- Always monitor your KPIs. After the new version of your software is too. You need to keep an eye on common KPIs that can include exception rate, log volume, server utilization and database performance to ensure consistent performance.
Project Management Best Practices
- Always invest time in recruiting the right human resources. Invest in talent and skills that are closer to your project requirements.
- Make accurate estimations to make sure that the resources, budget, time and efforts go well with the deadline of the project.
- Define both functional and nonfunctional project requirements in order to dedicate relevant resources.
- Define the system architecture to ensure that limitations and threats have been taken into account. Good system architecture will keep your project balanced so the limitations don’t hinder the progress.
- The proper documentation is just as important as software design and deployment. Prepare proper documentation for your software development plan including LLD, HLD, test reports, status reports, project plan, and requirement specifications.
- Maintain tractability through proper software control management. Manage the source code and all the related documents to make sure that each version is controlled.
- Always practice test management and good reporting.
Final thoughts: In software development, change must be consistent and recorded. Based on your experience over the years, you can write your own set of best practices and improve them along the way.
The important thing is that you use foresight, experience, and skills before allocating resources for a particular project to create a controlled project management.
Controlled management ensures sound estimations, rigorous testing, proper documentation, and proper tractability to measure success, which makes it a crucial step to consider at an early stage of development.
