Principles of Good Software Engineering

Coding, software development

In software development, as in project management, there are always competing priorities. And a team inevitably finds itself having to make compromises in order to find the delicate balance between these priorities and constraints. And rarely, if ever, do they succeed in reconciling them successfully and adequately. 

However, in today’s modern software world, this notion of compromise is no longer acceptable. Even “better, cheaper and faster” is no longer good enough. Today’s customers want top quality, regular updates, and a competitive price, and sometimes, their demands go much further. Successful software development now requires adding far more value. Products and services provided by software vendors must meet an ever-increasing set of criteria with no room for compromise. 

As the cost of technological infrastructure has fallen, higher performance storage, memory, and processors are now available to all developers at a more affordable price. At the same time, software development tools and methods have undergone interesting changes, with open source and low-cost tools being far more widely available.

Now, a single engineer can deploy a web application that supports auto-scaling, consisting of a message queue and a database, all in just minutes, matching the same results that used to take the entire team days or weeks. By using a highly scalable and available cloud infrastructure, the cost of hosting an application is a fraction of what it was just a decade ago. 

All of these factors have combined to make the software development scene far more competitive, and this makes following the principles of good software engineering all the more important. In this article, we’ll lay some of the essential ones down. 

#1 Timeliness 

 You must be able to deliver value to customers faster than your competitors while anticipating their growing expectations and ever-changing demands. 

#2 Adaptability

Vendors need to produce software that can adapt to ever-changing market conditions. In a world of supply chain constraints, tariffs, and unstable energy prices, businesses need their software to adapt and deal with various abnormal market conditions. Long gone are the days of rigid software design following pre-set formulae.

#3 Maintainability 

Technological advances have yet to overcome an inconvenient truth: 75% of the cost of software is related to maintenance and administration issues. Software design must contribute to the simplification and optimization of maintenance processes. If you want to earn long-term clients, you need to pay a lot of attention to maintainability. 

#4 Automation 

 When it comes to development, it is essential to leverage automation tools and methods for the design and deployment phases and to limit the slowdowns caused when processes rely on manual tasks. As the demand for skilled developers grows, the cost of developers’ time increases. You don’t want your developers to spend hours doing unproductive tasks. Automation is an essential tool to help make your team more competitive. 

#5 Scalability

Scalability must be at the heart of the software architecture. To truly reach scalability, the software you design must be truly open to allow for growth from 20 to 20,000 and from 20,000 to 20 million users without having to touch the underlying software architecture or, worse yet, force the customer into a situation where the product must be completely replaced. But scalability isn’t just about the number of users: it’s also about the volume of data, the complexity of the application, and the number of developers that can concurrently work on the project.

#6 Measurability 

software should measure and provide key metrics, reports, and business outcomes that DevOps, site reliability engineers (SREs), and business teams can leverage to improve business performance and success.

#7 Resilience 

In the event of a problem, a well-engineered software program must be able to recover its operation, quickly restore lost functionality, or prevent data loss to ensure that it does not negatively impact the business and customer experience. Regular backups, trace logs, and error handling all play vital roles here. 

Conclusion 

In conclusion, it is not a matter of meeting some of the criteria here. If you want to be successful, It is imperative to meet all of them, otherwise, a competition that provides excellent product engineering services will take care of it.
