What is reverse engineering and SQA?

Reverse engineering is the process of dividing the project to see how it works. While SQA is an abbreviation of software quality assurance which ensures quality in software. Here in this article, we’ll elaborate on what is reverse engineering and SQA

What is reverse engineering and SQA?

Reverse Engineering

Firstly, Reverse-engineering is the action of disassembling an object to see how it works. Secondly, It is done primarily to examine and increase knowledge about the way something works but frequently is used to duplicate or improve the object. Several things could be reverse-engineered, counting software, physical machines, military technology as well as even biological functions associated with how genes work.

Working of Reverse engineering Process:

The process of reverse engineering is particular to the object on which it’s being achieved. There are 3 overall steps that are common to all reverse-engineering processes. They include:

  • Information extraction.  The object being reverse-engineered is deliberated, info about its design is extracted and that info is observed to regulate how the pieces fit together. In reverse software engineering, this might need assembly source code and associated design documents for study. It may also include the use of tools, for example, a disassembler to break the program distinctly into its essential parts.
  • The composed info is abstracted into a theoretical model, with each piece of the model elucidating its function in the total structure. The effort of this stage is to take info specific to the unique and abstract it into an overall model that can be used to escort the design of new systems or objects. In reverse software engineering, this might take the shape of a data flow diagram or a structure chart.
  • This comprises studying the model and testing it in many situations to confirm it is a genuine abstraction of the original object or system. In reverse engineering, this might take the shape of software testing. Once it is tested, the model could be engaged to reengineer the actual object. How to fix the error code?


Purpose of Reverse Engineering:

Occasionally, the aim of reverse-engineering software or hardware is to find a way to make a similar product more reasonably or because the inventive product is no longer available. In information technology, Reverse-engineering is also realistic to address compatibility issues and make the hardware/software work with other hardware/software or operating systems that it wasn’t originally well-suited with.

Its main drive is to find out how a system or object works. There are numerous reasons to do this. Reverse-engineering could be used to learn how somewhat works and to return the object or to make a similar object with additional improvements.


Examples of reverse-engineering

  • Reverse-engineering varies relying on what it is being realistic to and the drive of reverse-engineering the technology. Common examples involve:

Computer parts

  • If a manufacturer of a processor wishes to see how an opponent’s processor works, it could buy a competitor’s processor, reverse-engineer it and then use what it studies to make its own processor. This process is not legal in several; countries and it needs a great deal of expertise and is expensive.


  • There are some occurrences where reverse engineering is realistic to undo software. A shared example is to adjust a program written for use with 1 microprocessor to another. Other examples include rebuilding lost source code, reviewing how a program performs specific operations, enlightening performance, and fixing errors, or correcting bugs when the source code is not accessible.

What is reverse engineering and SQA?

Software quality assurance and Practices:

SQA or simply Software Quality Assurance is the simplest method to reassure quality in the software. Firstly, It is the set of practices that confirm procedures; measures along standards are proper for the project and applied correctly.

Secondly, Software Quality Assurance is a procedure that works comparable to the development of software.

Thirdly, Software quality assurance is actually a practice of checking that software development projects conform to a predefined set of standards. It underlines the process of the development of software. Thus those problems can be stopped before they become a major issue. It is a kind of Umbrella movement that is applied all over the software process.


Major Software Quality Assurance Activities:

  1. SQA Management Strategy:

Firstly, Make a plan on how we will carry out the SQA all over the project. We have to think about which set of software engineering practices are the best for projects as well as Check the level of SQA team skills.

  1. Set The Check Points:

Secondly, The team of SQA should set checkpoints. Assess the performance of the project based on collected data on different checkpoints.

  1. Multi testing Strategy:

Thirdly, Do not rely on a single testing method. When you have a lot of testing tactics accessible use them.

  1. Measure Change Impact:

The modifications for making the regulation of an error occasionally lead to more errors keeping the measure of the influence of change on the project. Fourthly, Reset the new modification to change studies the compatibility of this fix with the complete project.

  1. Manage Good Relations:

In the working environment handling decent relations with other teams included in the project, development is obligatory. The bad relation of the SQA team with the programmer’s team will impact directly and badly on the project.


Advantages of Software Quality Assurance (SQA):

  1. SQA is valuable in the condition of no care for a long time.
  2. High-quality commercial software upturns the market share of the company.
  3. Taming the procedure of creating software.
  4. Mends the value of the software
  5. SQA makes high-quality software.
  6. The high-quality application keeps time and cost.
  7. SQA is helpful for better reliability.


The disadvantage of SQA:

There are a number of disadvantages to quality assurance. Some of them include adding more properties, hiring more workers to help uphold quality, and many more.

Software Quality Assurance has:

  1. Operative software engineering technology
  2. Quantity and reporting tool
  3. A tactic of quality managing
  4. Formal technical evaluations
  5. Multi testing plan
