Technology advances each and every day, so as business management which needs to

 

keep pace with these advancements. The changes in firms are usually very quick, and therefore it

 

requires the management to have the visibility of all their business processes. These changing

 

requirements are the key factors that prompt companies need stable and flexible IT solutions

 

which assist in handling the business more efficiently increase the productivity of the firm and

 

aiding in the reduction of recurrent costs incurred when dealing with such problems.

 

The Amazon Company uses the latest and the modest information technologies to

 

develop and maintain its competitiveness in the Internet retailing business, where it has thrived

 

to become the most successful of all. This electronic commerce and cloud computing company

 

utilize big data analysis and applications relating to e-commerce which is accessible using a web

 

browser and centered on a database, (Kelly and London, 1983). The hiring of computing

 

expertise in this company has ensured the maintenance of a consistent and quality website that

 

has been the key drive to thrive off the enterprise.

 

Quality assurance is a very crucial step in the development process of a website.

 

Presentations on a website speak volumes to many accessible clients (Pokorny?, 2011). To attain

 

the quality assurance required, it, therefore, takes a company to enforce various quality control

 

standards as well as improving the processes that are utilized during the production of the

 

website, its components as well as its contents. The Amazon Company puts great emphasis on

 

quality assurance to its customers, and that is why (www.amazon.jobs, 2016) this business is just

 

calling for the voice of the client. For instance; the Inventory Control Quality Assurance (ICQA) is

 

the department assigned the mandate to report on how the company is following its processes;

 

finances and customers respectively.

 

Any success of a particular web project depends on the defined process as well as the

 

dedicated resource. Requirement testing, design testing, and functionality testing are needed in

 

any quality assurance process. For example, the Quality Assurance function of the (ICQA) is

 

concerned with satisfaction of the customers. According to www.amazon.jobs, (2016), The

 

FRM03_Assignment brief_14.11.2012 Page 6 Amazon Company is obsessed by the clients, and that is why the customer service and operations

 

are used to determine if the client is happy and yearn to make changes on their website so as to

 

suit the needs of their consumers. The SQA should, therefore, be reliable, functional, usable,

 

safe, as well as supportive so that it can be more efficient.

 

The world is becoming massively interconnected, and therefore there is a ready

 

coexistence among various people and systems some of which are hostile either within the

 

country or internationally. It has made problems global and costly for Amazon to counteract

 

(CAMERON, 2000). Developing an IT system with a database at its center has proved to be

 

difficult because of frequent security misuse, vulnerabilities of the systems, labor intensive

 

software development as well as crises having far-reaching consequences (Harris and Hutchison,

 

2007).

 

The system development involves various cycles. According to www.tutorialspoint.com

 

(2015), the stages are: The planning

 

senior includes the members inputting data from the market survey and also sales customers,

 

department.

 

approaches stage The

 

to various be technical taken are determined here. In the defining stage, defining and documenting of a product is done, and assurance is

 

made by use of SRS software. The next step involves designing and design Document

 

specification is used. The building is put into place, and here C, C++, PHP, and Java are used. After

 

that testing is done, and it is made sure that it reaches the standards of SRS. Finally, deployment

 

is done, and the User Acceptance testing is done to determine the acceptability.

The major factor contributing to Information Systems quality is the way a company

 

comprehensively and systematically tests the system to obtain viable and helpful results.

 

Inadequate testing is, therefore, the principal cause of numerous software defects which FRM03_Assignment brief_14.11.2012 Page 8 adversely affect the perceived quality of the software. Consequently, it also leads to time wastage

 

as a result of reworks as well as incur high maintenance costs. Writing the plan is usually not

 

difficult, and the Amazon Company has been following these procedures regarding developing a

 

software test plan, a software test description, and a software test report. It is the reason that

 

has made this enterprise very successful.

 

1) A software test plan (STP)

 

A Software Test Plan (STP) is usually designed in a way that it dictates the scope,

 

approach, schedules, and approaches to testing the activities of the enterprise. It is therefore

 

equally important for the Amazon Company to identify items, features, types of testing to be

 

conducted, personnel for testing, resources, as well as the schedule for the testing (Harris and

 

Hutchison, 2007).
