How To Become a Software QA Expert

Being a software QA expert requires specialized skills in software programming and development. Having an expertise in the Quality Assurance (QA) industry needs dedication and patience. Software Quality Assurance is a specialization in the field of software engineering and development, where experts ensure software quality. A Software Quality Assurance (SQA) expert monitors the software engineering process developed by software programmers to maintain ninety to a hundred percent software efficiency. SQA experts must comply with the international standards set by the company or corporation.

The scopes of the Software Quality Assurance experts' routine are as follows:

Software design - SQA experts must check the efficiency of the software's architectural planning. These are parts of the whole software design that SQA experts must consider:

  • Software compatibility - SQA must check if the created software would run in various systems and devices. The backwards-compatibility of the software must be applied for earlier versions of the software.
  • Software extensibility - SQA must check if the product is ready and tested for system upgrade without having the changing the whole system structure.
  • Fault-tolerance - SQA must check if the software can still run after a system crash. The software must also be tested if it could repair system errors.
  • System maintainability - the software should be tested if the software is able to revert to its previous settings after system upgrade without failure or crashes.
  • Modularity - SQA must isolate every individual parts or components and maintain its stability before applying the parts to the whole system for easier software maintenance.
  • Software packaging - the boxes, manuals and printed materials used marketing must be double checked before product distribution.
  • Robustness - SQA expert should monitor the system to function under pressure. The software must be able to respond with various invalid or unpredictable inputs.
  • System security - the software should be checked for "bugs" or "loop holes" to prevent security breach and "crackers" from entering the system.
  • Usability - The interface must be "user friendly" for clients operating the software.
  • Coding - SQA experts should verify and test the software if the programming codes are generated correctly and properly for optimized performance.

Source code management (SCM) - Revision control and source code management is done after coding compression and changing it into readable file formats such as documents, executable programs, and other managed information stored as files. Source code management (SCM) includes file locking and version merging which are used for file identity.

Code review - SQA experts re-checks the whole system for beta testing before introducing the software package to the consumers.

Software configuration management - SQA experts maintain the stability and identity of the configuration of the software to serve as a collection of data regarding the changes made to the entire system. Software configuration management has four implemented processes which are:

  • Configuration management - a method of identifying the set properties in the configuration of the system. All of the configurations made and changed are recorded for further comparison and analysis.
  • Configuration change control - a process where changes in the configuration should be approved for re-base lining.

Configuration status accounting - This is a collection of reports and records of a configuration base line.
