Usability is defined as an approach to website design intended to enable the completion of user tasks efficiently and effectively. Usability is an important aspect of website design, ensuring that the use of navigation and links enables users to access information in the shortest possible time. Usability testing is the process of observing users performing representative tasks using the system. It involves identifying representative users, assigning them prescribed tasks, and observing their reactions and behaviour. 4 stages of use-case analysis:Use-case analysis is a user-centred approach to modelling system requirements. a.identify actors b.identify use-cases c.relate actors to use-cases d.develop use-case scenarios.4 key elements of site design? ●site design and structure (i.e., site style, personality, organization, and navigation schemes)●page design (i.e., page elements, use of frames, resizing, consistency of layouts, support for printing)●content design (e.g., scope and format of content, use of hyperlinks)●mobile design (e.g., type of mobile versions, options that fit with users' needs and capabilities).Why is Web accessibility important for successful website design? Web accessibility is an important design factor to ensure that the site is accessible to all main users regardless of theirsituation (e.g., physical abilities, browser, access platform).

LESSON 6: SCMChapter 6 pp. 332-413Supply chain management (SCM) deals with managing the flow of goods, services, and information among suppliers, manufacturers, wholesalers,
distributors, stores, and consumers. The complexity and cost of supply chains have increased significantly in the past two decades. Companies also realize that customer satisfaction (or dissatisfaction) is linked to supply chain performance. In addition, just-in-time, zero-stock, total quality, and category management offer a number of benefits.SCM is a source of competitive advantage and potential increased profit margin. 3 SCM Issuespoor information flowinaccurate datalack of timely information about demand forecasts.2 Solutionsa)Industry exchanges, a company can collaborate with its business partners to reduce inventories and transaction costs, optimize resource utilization, and eliminate any waste from the value chain.b)Information systems are used to increase the efficiency of information flow by •delivering more information (e.g., sales data in Tesco’s TIE system) •analyzing information (e.g., alerts about a large order) •delivering information more rapidly (e.g., reduced lead times in e-procurement).
