Software quality assurance (SQA) systematically finds patterns
and the actions needed to improve development cycles. Finding and
fixing coding errors can carry unintended consequences; it is possible
to fix one thing, yet break other features and functionality at
the same time.
SQA has become important for developers as a means of avoiding
errors before they occur, saving development time and expenses.
Even with SQA processes in place, an update to software can break
other features and cause defects — commonly known as bugs.
There have been numerous SQA strategies. For example, Capability
Maturity Model Integration (CMMI) is a performance improvement-focused
SQA model. CMMI works by ranking maturity levels of areas within
an organization, and it identifies optimizations that can be used
for improvement. Rank levels range from being disorganized to being
fully optimal.
Software development methodologies have developed over time that
rely on SQA, such as Waterfall, Agile and Scrum. Each development
process seeks to optimize work efficiency.
- Waterfall is the traditional linear approach
to software development. It's a step-by-step process that typically
involves gathering requirements, formalizing a design, implementing
code, code testing and remediation and release. It is often
seen as too slow, which is why alternative development methods
were constructed.
- Agile is a team-oriented software development
methodology where each step in the work process is approached
as a sprint. Agile software development is highly adaptive,
but it is less predictive because the scope of the project can
easily change.
- Scrum is a combination of both processes
where developers are split into teams to handle specific tasks,
and each task is separated into multiple sprints.
To implement a QA system, first set goals for the standard. Consider
the advantages and tradeoffs of each approach, such as maximizing
efficacy, reducing cost or minimizing errors. Management must be
willing to implement process changes and to work together to support
the QA system and establish standards for quality.

Manual testing is a critical step in the software development
process that ensures high-quality products. It involves executing
tests manually to identify defects, errors, or bugs in the software.
You get to evaluate user experience, user interface, and functional
aspects of the software. In today's world, there is a wide range
of software testing solutions available to help with manual testing.
These solutions offer different levels of support, from simple test
case management to complex test automation. But manual testing remains
an important aspect of software development that cannot be replaced
by automation alone.
Manual Testing is one of the most fundamental testing processes
as it can find both visible and hidden defects of the software.
The difference between expected output and output, given by the
software, is defined as a defect. The developer fixed the defects
and handed it to the tester for retesting.
Manual testing is mandatory for every newly developed software
before automated testing. This testing requires great efforts and
time, but it gives the surety of bug-free software. Manual Testing
requires knowledge of manual testing techniques but not of any automated
testing tool.
Manual testing is essential because one of the software testing
fundamentals is "100% automation is not possible."
