1. Major Roles on a Project Team

Project teams are composed of various roles essential for successful project execution. The core roles include the project manager, who oversees planning, execution, and delivery; the business analyst, responsible for gathering requirements and ensuring the system aligns with business needs; the systems analyst, who translates business needs into technical specifications; developers or programmers who build the system; testers who verify functionality; and stakeholders or clients who provide requirements and feedback (Schwalbe, 2018). Effective communication and collaboration among these roles foster project success. Each role has specific responsibilities, but their collective effort ensures the project meets its goals within scope, budget, and schedule. These roles are dynamic and often overlap, emphasizing the importance of team synergy in delivering high-quality systems.

2. Role of the Systems Analyst in Developing Information Systems

The systems analyst acts as a bridge between business needs and technical solutions. They analyze business processes, gather requirements, and develop system specifications. Their role involves conducting feasibility studies, designing data models, and collaborating with users to refine system designs (Avison & Fitzgerald, 2006). Systems analysts also assess existing systems for improvements, ensuring new systems are effective, scalable, and aligned with organizational goals. They play a pivotal role during the analysis and design phases of the SDLC, translating user needs into technical specifications that developers can implement. Their critical thinking ensures systems are not only functional but also efficient and user-friendly (Dennis, Wixom, & Roth, 2015). Effective systems analysts facilitate communication, reduce misunderstandings, and help deliver systems that truly address business problems.

3. Objective of Developing Use Cases during Systems Analysis

Use cases are developed to capture functional requirements of a system from an end-user perspective. The primary objective is to specify how users interact with the system to achieve specific goals, enabling analysts to understand user needs thoroughly (Cockburn, 2001). Use cases help identify system requirements clearly, guide system design, and facilitate communication among stakeholders. They serve as a bridge between non-technical users and developers, ensuring the technical solution aligns with actual business processes. Additionally, use cases assist in identifying exceptions and alternative flows, making the system more robust. Developing use cases improves understanding, reduces ambiguities, and enhances system usability, ultimately contributing to the success of system development projects.

4. Purpose of the Analysis Phase of the SDLC

The analysis phase of the Systems Development Life Cycle (SDLC) aims to understand and document the business requirements and current system limitations before designing a new system. This phase involves analyzing organizational needs, defining system requirements, and establishing the scope of the project (Larman & Basili, 2003). The purpose is to gather detailed, precise information to guide system design, ensuring the final product addresses user needs and business objectives. It also involves process modeling, requirement validation, and feasibility analysis. Proper analysis prevents scope creep, reduces errors, and increases the likelihood of project success. Ultimately, this phase creates a solid foundation for subsequent design and implementation phases, minimizing costly changes downstream.

5. Business Rules Expressible by an ERD with Examples

Entity-Relationship Diagrams (ERDs) primarily depict relationships between entities and do not explicitly capture detailed business rules. However, high-level rules can be inferred, such as constraints on relationships. For example, in a university database, an ERD might show that each student enrolls in multiple courses, but no student can enroll in courses without being registered. Another example is that each order must be associated with one customer; this enforces a one-to-many relationship. These high-level rules can guide database design, but detailed constraints like "a student cannot enroll in more than five courses per semester" are typically incorporated through database logic or application rules (Elmasri & Navathe, 2015). ERDs serve as foundational tools for understanding system structure rather than detailed business rules, which are often added during the logical or physical design phases.

6. Logical Process Models vs. Physical Process Models

Logical process models represent how a system should function independent of technical implementation. They focus on what the system does, capturing workflows, business rules, and data flows without considering hardware or software constraints (Watson & Gable, 2010). Physical process models, however, depict how the system will be implemented technologically, including hardware architecture, system components, and database structures. Logical models are essential during analysis to understand process requirements, while physical models are used during system design to specify technical details necessary for development and deployment. Differentiating these models helps ensure that business needs are accurately translated into implementable technical solutions, improving system efficiency and maintainability.

7. Two-tier, Three-tier, and N-tier Client–Server Architectures

The architecture of client-server systems varies based on the distribution of functions across different layers. In a two-tier architecture, the client directly communicates with the server, which handles data storage and processing. It’s simple but can lead to scalability issues. A three-tier architecture introduces an intermediate layer, commonly called the application server, which manages business logic, separating it from the data layer and client interface, thus improving scalability and maintainability (George et al., 2013). N-tier architecture extends this concept further, adding multiple layers (e.g., presentation, application, data, and services), allowing for more modular, flexible, and scalable systems. These architectures influence performance, security, and scalability, and choosing the right approach depends on system complexity and organizational needs.

8. Primary Activities of the Design Phase of the SDLC

The design phase translates system requirements into detailed specifications for developers. Key activities include designing user interfaces, database structures, system architecture, and detailed process workflows. This phase involves creating data flow diagrams, screen layouts, and system architecture diagrams (Dennis et al., 2015). The goal is to produce a blueprint that developers can implement, ensuring all components work cohesively. Additionally, during this phase, hardware and software specifications are finalized, and security measures are integrated. Proper design documentation facilitates smoother development, testing, and deployment, while also providing a basis for future modifications. The focus on detail and accuracy during this phase reduces errors and ensures the system meets user expectations.

9. Importance of Content Awareness

Content awareness involves understanding the context, relevance, and appropriateness of information presented to users. It is crucial in designing user interfaces and information systems because it enhances user experience and helps prevent information overload or miscommunication (Shneiderman & Plaisant, 2010). Content awareness ensures that users see only relevant data, prompts, and alerts, which improves decision-making efficiency. For example, in a healthcare information system, content awareness ensures that nurses and doctors receive pertinent patient alerts without unnecessary distractions. In addition, content awareness supports accessibility, ensuring that information is appropriately tailored to diverse users, including those with disabilities. Ultimately, content awareness fosters clarity, improves usability, and increases overall system effectiveness.

10. Three Important User Interface Design Principles

Effective user interface (UI) design relies on principles that enhance usability and user satisfaction. First, consistency is vital; UI elements should behave uniformly across the system to reduce the learning curve and prevent user errors (Nielsen, 1994). Second, feedback is essential; users must receive immediate, clear responses to their actions, enabling them to understand system status and outcomes. Third, simplicity involves designing interfaces that are straightforward, with only essential features visible, minimizing cognitive load. Simplicity increases efficiency and reduces user frustration. Together, these principles contribute to intuitive, accessible interfaces that facilitate user engagement and productivity.

11. Blockchain Technology in Various Industries

Blockchain technology, characterized by its decentralized and secure ledger system, has transformative potential across multiple industries, including finance, supply chain, healthcare, and real estate (Tapscott & Tapscott, 2016). Its core advantage is increasing transparency, reducing fraud, and enhancing security through cryptographic methods. For instance, in the financial industry, blockchain can streamline cross-border payments, reducing transaction times and costs. It also supports smart contracts, automating complex processes. The technology's decentralization minimizes the risk of centralized points of failure, potentially decreasing operational costs and improving trust among stakeholders. Moreover, in supply chain management, blockchain improves traceability of products, reducing fraud and enhancing consumer confidence. As a secure, transparent platform, blockchain has the potential to revolutionize business processes, reduce costs, and foster innovation in digital transactions (Swan, 2015).

12. Failed Projects and New Discoveries: The Case of the Google Wave

Google Wave was launched in 2009 as an innovative real-time communication and collaboration platform, but it failed to gain widespread adoption and was discontinued in 2012. Despite its failure, Google Wave led to new insights into collaborative technology design and influenced future products like Google Docs and Hangouts (Barrett, 2014). The failure of Google Wave demonstrated the importance of simplicity and user adoption in collaborative tools, emphasizing that technical novelty alone cannot guarantee success. The lessons learned contributed to a better understanding of user-centric design and real-time system usability. Additionally, the project highlighted the importance of incremental development and market readiness, ultimately shaping subsequent Google products that are more aligned with user needs. Failures like Google Wave underscore that setbacks can lead to valuable innovations and strategic improvements in technology development.
