Soft­ware Qua­li­ty Assuran­ce (also abbre­via­ted as SQA), can be defi­ned as a sys­te­ma­tic pro­cess which ensu­res that the deve­lo­ped soft­ware meets and com­plies with the stan­dar­di­zed qua­li­ty spe­ci­fi­ca­ti­ons. It keen­ly checks the adhe­rence to the soft­ware pro­duct stan­dards, pro­ce­du­res and pro­ces­ses all throughout the soft­ware deve­lo­p­ment life cycle and also the test cycle. The eva­lua­ti­on is done through pro­duct eva­lua­ti­on, pro­cess moni­to­ring, pro­ject manage­ment, and more.

Soft­ware qua­li­ty assuran­ce main­ly focu­ses on eli­mi­na­ting the bugs, enhan­cing per­for­mance, impro­ving app­li­ca­ti­on secu­ri­ty, impro­ving per­for­mance tuning, pro­tec­ting data and fin­ding mini­mum hard­ware requi­re­ments. It encom­pas­ses the who­le of soft­ware deve­lo­p­ment pro­cess, inclu­ding pro­ces­ses like coding, requi­re­ments defi­ni­ti­on, tes­ting, soft­ware design, source code con­trol, pro­duct inte­gra­ti­on, code reviews, release manage­ment, and soft­ware con­fi­gu­ra­ti­on manage­ment. SQA is typi­cal­ly orga­ni­zed into goals, abi­li­ties, com­mit­ments, mea­su­re­ments, acti­vi­ties, and verifications.


SQA prac­ti­ces are usual­ly imple­men­ted in many types of soft­ware deve­lo­p­ment, regard­less of the type of under­ly­ing soft­ware deve­lo­p­ment models being used. It incor­po­ra­tes and also imple­ments various soft­ware tes­ting metho­do­lo­gies. Ins­tead of che­cking for soft­ware qua­li­ty after com­ple­ti­on, it pro­ces­ses the tests for qua­li­ty in each sin­gle pha­se of the deve­lo­p­ment cycle untill the soft­ware is ful­ly com­ple­te. With SQA, the soft­ware deve­lo­p­ment pro­cess will only move into the next step when the cur­rent pha­se ful­ly com­plies with the requi­red qua­li­ty standards.

The two main are­as of focus inclu­de func­tio­n­al qua­li­ty assuran­ce and struc­tu­ral qua­li­ty assurance.
• Func­tio­n­al Qua­li­ty Assurance
This shows just how well a soft­ware pro­duct con­forms to or com­plies with the basic design, based on the func­tio­n­al requirements.
• Struc­tu­ral Qua­li­ty Assurance
The struc­tu­ral qua­li­ty of a soft­ware pro­duct is usual­ly deter­mi­ned by keen ana­ly­sis of the software’s source code and inner struc­tu­re. This reflects just how well a pro­ject meets the non-func­tio­n­al requi­re­ments like secu­ri­ty, usa­bi­li­ty and acces­si­bi­li­ty, which hel­ps pro­per­ly deli­ver func­tio­n­al requirements.

Struc­tu­ral qua­li­ty assuran­ce is done so as to check the com­pli­an­ce of a pro­duct with the set soft­ware archi­tec­tu­re spe­ci­fi­ca­ti­ons. It’s done by the pro­ject deve­lo­per. On the other hand, func­tio­n­al qua­li­ty assuran­ce is about che­cking the over­all func­tio­n­a­li­ty com­pli­an­ce with the set requi­re­ment spe­ci­fi­ca­ti­ons, and is nor­mal­ly mea­su­red through soft­ware pro­duct testing.

Basi­cal­ly, the main rea­son of invol­ving SQA in the soft­ware pro­duct deve­lo­p­ment pro­cess is to ensu­re that the final pro­duct meets the requi­red spe­ci­fi­ca­ti­ons, and com­plies with the set stan­dards. It ensu­res the deve­lo­p­ment of a high qua­li­ty soft­ware. A qua­li­ty assuran­ce sys­tem can actual­ly incre­a­se a company’s credi­bi­li­ty and cus­to­mer con­fi­dence, impro­ve the work pro­ces­ses, incre­a­se effi­ci­en­cy, and enab­le a com­pa­ny to com­pe­te with the others much better.

Knowing that the qua­li­ty of the soft­ware you have has met the requi­red stan­dards is essen­ti­al. Stu­dies have reve­a­led that many instal­la­ti­ons are not always done right for the first time; this nor­mal­ly results in dama­ges and repair expen­ses. You can actual­ly avoid this by con­trac­ting a pro­fes­sio­nal soft­ware tes­ting com­pa­ny which will pro­fes­sio­nal­ly test your soft­ware, and give the soft­ware qua­li­ty assuran­ce. The SQA com­pa­ny will also tho­rough­ly check your web­site for com­pli­an­ce with the requi­red spe­ci­fi­ca­ti­ons, and give you a detail­ed report about out the fin­dings. Get­ting a SQA test done befo­re going live with your web­site will great­ly help you avoid plug­ging into loo­p­ho­les, which could lead to mas­si­ve losses.
