Design principle of Software Engineering

Last Updated on February 21, 2023 by


The primary objective of software design principles is to provide tools for successfully managing the complexities of system design. Accurately regulating complexity reduces the labor required for design and the risk of incorporating flaws throughout the design phase. In many instances, organizations have intended to bring innovation to their program but were unable to do so due to their rigidity. 

This article will take you go through various design concepts that every software engineer and developer should be aware of. These guidelines apply to how users create a system’s design, how to design certain elements, and also how to write code. These are simply a few considerations to keep in mind while building or deploying a technology. If you choose to follow these, they can make your experience much better in the future. 

Design Principles of Software Engineering

Segmentation of problem:

Split up and conquer is a basic concept in every problem-solving scenario, including design. It entails decomposing a difficulty into simpler, more manageable subtasks. The notion is that certain challenges are complicated to fix because of their complexities. You can break such challenges down into manageable parts to make things smoother. In the long term, addressing these minor chunks would simplify things to address the broader challenge. The advantages of problem segmentation are:

  • Software is simple to comprehend.
  • Software gets more straightforward to test.
  • Modifying software is simple.
  • The software is simple to administer.
  • The expansion of software is simple.

Create a flexible layout:

It simply refers to anticipating future system modifications while designing for flexibility. Software may be straightforward now, but it will become increasingly complicated in the long term. You might want to include a lot of information or replace an object’s functionality with an improved version. People frequently create designs to suit today’s usage. They are unconcerned about the idea that the venture will be scaled up in the coming times. It is more frustrating for a programmer than having to rebuild what they’ve already done. Repairing the existing code base using novel functionality will not suffice in this situation. Creating a completely new design is far simpler than adapting an established one. 

Elevate abstraction level:

An abstraction is a feature that allows a developer to think about a component at a high level without worrying about the technical aspects of implementation. It refers to a system for obscuring non-essential elements and portraying just the pivotal characteristics of an object so that you can concentrate on significant data at a time. Abstraction can be applied to both existing components and newly developed components. It eliminates the redundancy of code while also preserving privacy.

Subsiding Coupling:

Coupling happens when programs, methods, or resources are strongly reliant on one another and are highly interconnected. Since some of the program’s parts are dependent on the ruptured module, the entire system may be spoiled when one of them alters or fails. Having a highly coupled system is easier to implement in the beginning stages, but it will be much harder to debug and fix in case of any component failure. It’s not unusual to have networks that are so closely interwoven that determining where the coupling occurs is challenging. We might be in a position wherein one doesn’t understand why one module isn’t operating while another, hidden beneath different coupling levels, may malfunction. 

 Reinforcing Cohesion:

Cohesion refers to putting things collectively that makes logical sense — like the packaging. You can choose to create your modules, sections, or subclasses consistently from a development perspective. Cohesion organizes your code and makes it easier to spot objects, streamlining the process. Using this approach, everything will fall into place, which will benefit users. 

These features make the need to learn software engineering in today’s technological era more prominent. To thrive in this competition-driven market, an individual should be well-versed in these functionalities.


Whenever we write code, we should consider creating it as useful and reusable as possible. It is inextricably linked to abstraction. However, we could try keeping it generic We could keep it generic i.e., somewhat more abstract, instead of formulating a procedure that performs one task effectively and only functions for one instance. This allows for reusability in various scenarios. Consider it like making a slight effort upfront and saving time later, rather than going back and reworking or creating other procedures to grasp this code.

Establish a portable design:

While setting up a system, remember that it may be implemented on a platform other than the one you’re presently focusing on. If you develop a web app solely for the website, porting it to an Android app, an iOS app, or a Microsoft desktop version will be expensive and time-consuming. To be capable of exporting, this could necessitate the creation of an altogether new platform. As a result, you should consider it when planning the systems.

Develop a testable design:

While functioning on complex networks and codebases, it’s critical to remember that designing for testability is vital. As we all begin with minor programs, practically every programmer has been implicated in it at some point. The programmers who create such large codebases built these so that they could verify what they developed. The conclusion is to make sure that if you develop a lot of programming in a large codebase, it must be testable and verifiable.

Emphasis on defensive design:

It simply implies making your code layman-proof so that even a newbie can understand your code. You must assume that everybody who uses your program, platform, or modules is a complete novice. That’s something you’ll have to envision. You must ensure that your error notifications are appropriate. Assure that you can handle any erroneous entries that are delivered to you. Check for legitimate error codes and appropriate alerts to assist the user. It must be anticipated by any user who uses it.


The software design principles are the foundation, or support infrastructure, for any program development and design. They are excellent guidelines and practices that must be followed throughout the software development process. It will assist skilled programmers in the long term in making improvements and maintaining services at their finest without destroying or distorting the software’s operating features.

Our software developers must master these approaches to maintain dominance in the software-dominated market. Ed-Tech as Great Learning offers advanced software engineering courses online that educate participants on developing software development abilities to work on cutting-edge technology. To enroll for these courses and make advancement intuition for bright future prospects.
