- a.delays early identification of potential threats to processes
- b.increases resources and general costs
- c.prevents the alignment of strategic objectives
- d.decreases quality, efficiency, productivity, and usability of the system
Answer
4-3 §4.1 source ↗
- a.It is a linear approach to software development and proceeds sequentially from one stage to the next.
- b.There are no considerations for environmental changes.
- c.The final work product is delivered in one package at the end of the process.
- d.It values individuals and interactions over processes and tools.
Answer
4-5 §4.1 source ↗
- a.Use a Waterfall approach to ensure all features are fully developed and tested before the first release, preventing any major changes after the launch.
- b.Follow an Agile development process to focus on delivering a minimum viable product (MVP), gather user feedback, and iterate on the app with each new release.
- c.Adopt a hybrid approach, combining elements of Agile and Waterfall, to maintain flexibility in development while still following a strict, sequential timeline.
- d.Use a Rapid Application Development (RAD) model to complete the app’s features as quickly as possible, with minimal user involvement during the development process.
Answer
4-7 §4.2 source ↗
- a.documented processes
- b.early delivery of the product
- c.meeting user functional requirements
- d.increased costs
Answer
4-9 §4.2 source ↗
- a.Focusing on user requirements can prevent misunderstandings during the development process but will not influence project costs or timeline.
- b.Incomplete or incorrect user requirements may lead to significant delays and increased costs, but addressing them in early stages helps avoid costly changes later.
- c.Analyzing user needs only at the final stages of development ensures that the system meets stakeholder expectations without wasting resources.
- d.Relying on visual tools, such as flowcharts, exclusively, will guarantee that user needs are fully understood and eliminate the risk of project delays.
Answer
4-11 §4.3 source ↗
- a.Logical designs include the specific hardware that will be used in the system.
- b.Physical designs incorporate business processes to visually represent the flow of data and the relationships between them.
- c.Logical designs provide a high-level representation of the system.
- d.Physical designs are used to build out the logical design.
Answer
4-13 §4.3 source ↗
- a.A systems design focuses primarily on choosing the right hardware to meet performance requirements, ensuring the system functions as expected.
- b.The systems design process creates detailed architectural and data specifications, balancing logical and physical components, while also identifying potential issues early through prototypes and iterative design.
- c.A systems design is only about developing the user interface, focusing primarily on aesthetics and ease of use.
- d.The systems design process is mainly concerned with generating the necessary documentation and does not need to consider user feedback or future scalability.
Answer
4-15 §4.4 source ↗
- a.Research helps create an app with the least amount of time and cost.
- b.Research tells you how to design the product.
- c.Research prevents costly mistakes and major changes later in the design process.
- d.Research provides new revelations about user needs.
Answer
4-17 §4.4 source ↗
- a.UI and UE work independently of each other.
- b.There is minimal difference between UI and UE.
- c.UE considers the interaction of the user with the design.
- d.UI looks at the design process, encompassing the user’s experience with all aspects of the company’s services.
