Question
Part 5 "Testing of Software Characteristics" “The test team has been struggling to achieve major benefits using the test execution tool sine they purchased it. Training in use of this tool has been given bt staff turn-over is rather high. Script maintenance seems to be a problem. A company wants to develop a web site to implement an on-line sales channel. Which TWO ISO 9126 quality attributes are most likely to be of importance? 1 credit [K2]

Explanation
For a web-based online sales channel, Usability (A) is critical because customers must intuitively navigate the site, find products, and complete purchases - poor usability directly drives cart abandonment and lost revenue. Portability (C) is equally vital because the site must function correctly across different browsers (Chrome, Firefox, Safari), operating systems (Windows, macOS, Linux), and increasingly mobile devices - a site that breaks in certain browsers locks out entire customer segments.
Accuracy (B) is a Functionality sub-characteristic covering correctness of calculations; while expected, it's a baseline concern for any system, not a distinguishing priority for an online sales channel. Fault-tolerance (D) is a Reliability sub-characteristic that matters for mission-critical systems but is not among the most important ISO 9126 attributes to prioritize when launching a new sales website. Installability (E) is a Portability sub-characteristic about ease of software installation - irrelevant here because web-based systems require no client-side installation.
Memory tip: Think "UP sells" - a web sales channel lives or dies on Usability (can customers buy easily?) and Portability (can customers reach it from any device or browser?).
