Lesson 5 - Questions Flashcards
Lesson Note
it is important to recognize that the customer interface and digital systems need to be secured against potential threats and risks. As well, businesses need to ensure that they are monitoring their electronic communications both internally and externally, and managers need to offer secure e-commerce transactions to their stakeholders.
Question 1: What is big data? What are the key characteristics of big data?
Big data refers to the vast amount of information, data, and customer records available to businesses through various touchpoints with customers and users. These touchpoints include point-of-sale transactions, desktop and mobile sites and applications, as well as social media. This vast range and many forms of data could present challenges that companies need to consider, including the large volume of data, variety of formats, velocity, and veracity.
Self-Assessment Question 1: What are the risks if analysis and design are not completed adequately?
The major risks that could arise from inadequate analysis and design include:
poor user interface wrong type of customer services (content and data) slow performance inefficient business processes poor security.
Self-Assessment Question 2: Distinguish between process analysis and data analysis.
The main distinction between process analysis and data analysis is related to scope. Process analysis reviews the sequence and speed of events in a business transaction, such as ordering or customer service. It involves the activities, tasks, and steps required to fulfill the process. Data analysis, on the other hand, reviews the data requirements and structure needed to support particular processes. It typically focuses on the type and details of information and data needed to support the business process.
Self-Assessment Question 3: What are workflow analysis and workflow management systems?
Workflow management (WFM) is the automation of information flows and provides tools for processing information according to a set of procedural rules. Workflow analysis is the first step in the process, and refers to identification and analysis of the requirements that enable automation. WFM systems are used by management to automate digital business processes by providing a structured framework to support business processes to be efficient, consistent, and integrated. Specifically, workflow management systems help
assign tasks to the right people
remind them about their tasks in progress or in queue
ensure collaboration and communication among people sharing tasks
access and retrieve the information required to complete the task
support management team in supervising and ensuring the team’s performance.
Examination Question 1: Summarize the purpose of process analysis.
There are two main purposes of process analysis. The first is to outline the system’s clearly defined purpose or objective and clearly defined inputs and outputs. The second is to identify the required workflows to support and manage business processes. Process analysis is intended to identify the main processes and their components, and then pinpoint inefficiencies in workflow that give rise to higher costs or longer cycle times.
Examination Question 5: Describe the stages of data modelling with reference to a database for an e-procurement system.
With reference to a database for an e-procurement system, the three stages of data modelling are
identify entities (e.g., product, supplier, purchase order, invoice, payment)
identify attributes of entities (e.g., fields for supplier name, phone number, address)
identify relationships between entities.
Question 1: What is user-centred design? What are the major elements required for a well-designed interface?
User-centred design is based on optimizing the user experience according to all factors, including the user interface, which affect this. It calls for careful analysis of user needs from the full range of types of audiences for a site. It is important to clearly define and examine the list of important users, and
their purpose in accessing the site
how frequently they will visit the site
their experience and expertise
their profiles (e.g., language, country of origin)
the type and format of the information they request and need
the type of browsers they use, screen size, number of colours, and so on.
Question 2: What is usability and usability testing?
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.
Question 3: What is use-case analysis? Describe its main stages.
Use-case analysis is a user-centred approach to modelling system requirements. The main stages are
identify actors
identify use-cases
relate actors to use-cases
develop use-case scenarios.
Question 4: What are the key elements of site design?
The main key elements of site design are
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).
Question 5: 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 their situation (e.g., physical abilities, browser, access platform). For example, if a company offers its services globally, it must consider factors such as culture, legal requirements, language, and other requirements of international users. For the visually impaired to use the site, for example, it is necessary to consider the use of elements such as images and animations, multimedia, hypertext links, graphs and charts, frames, tables, and so on.
