System Analysis and Design (SAD) - Q&A - Technology369kk

 In this post, we will be cover all important questions of SAD so let's get start now.  

  • Explain SDLC in Detail.   
  • Factors Affecting Quality in System Development: Briefly describe these factors.
  • What is a Dataflow Diagram? How does it differ from a structure chart?
  • External vs. Internal Information: When should an analyst rely more on external information?
  • Feasibility Study: Define and discuss the types and process of feasibility studies.
  • Short Notes on Any Two:
    • a) Prototyping
    • b) JAD (Joint Application Development)
    • c) System Analyst
    • d) Flowchart 

    Explain SDLC in Detail. 

    The System Development Life Cycle (SDLC) is a structured approach used to develop information systems and software applications, consisting of several phases that guide a project from initiation through deployment and maintenance. Each phase in SDLC has a specific purpose, ensuring systematic progress in building a high-quality system that meets or exceeds customer expectations.

    Here’s a detailed breakdown of each SDLC phase:

    1. Planning

    • Objective: Establish the project's purpose, scope, resources, budget, and timeline.
    • Activities:
      • Identify and define the problem or opportunity.
      • Assess the feasibility of the project.
      • Define project goals and objectives.
      • Prepare an initial project plan.
    • Outcome: Project Charter or Initial Plan outlining the project’s roadmap.

    2. Requirements Gathering and Analysis

    • Objective: Understand the end-user needs and requirements.
    • Activities:
      • Collect requirements through interviews, surveys, and workshops.
      • Analyze and document these requirements to create clear, measurable specifications.
      • Define both functional requirements (what the system should do) and non-functional requirements (how it performs tasks, like security and performance).
    • Outcome: Requirements Specification Document.

    3. Design

    • Objective: Create a blueprint for the system that will meet the defined requirements.
    • Activities:
      • Develop system architecture and data flow diagrams.
      • Design user interfaces, system models, and databases.
      • Prepare detailed technical specifications for components, modules, and interfaces.
    • Outcome: Design Documents, including High-Level Design (HLD) and Low-Level Design (LLD).

    4. Development (Implementation)

    • Objective: Write code to build the system based on design specifications.
    • Activities:
      • Developers code each component, module, and feature as defined in the design phase.
      • Integrate different modules and ensure they work together.
      • Conduct code reviews, optimize code, and apply version control.
    • Outcome: Working system or software with all functionalities in place.

    5. Testing

    • Objective: Identify and resolve defects, ensuring the system is error-free and meets quality standards.
    • Activities:
      • Execute different types of testing, such as unit testing, integration testing, system testing, and user acceptance testing (UAT).
      • Validate functionality, performance, and security.
      • Document and fix any issues or bugs found during testing.
    • Outcome: A stable and functional product ready for deployment.

    6. Deployment

    • Objective: Release the final product to the end users.
    • Activities:
      • Move the system to a live environment (production).
      • Perform necessary configurations and monitor for any potential issues.
      • Provide user training if needed.
    • Outcome: Fully functional system available for users.

    7. Maintenance and Support

    • Objective: Ensure the system remains operational and up-to-date over time.
    • Activities:
      • Address and fix any issues that arise post-deployment.
      • Perform regular updates and add enhancements based on feedback.
      • Conduct periodic maintenance to optimize performance.
    • Outcome: Updated and well-maintained system that continues to meet user needs.

    Benefits of SDLC

    • Provides a structured and systematic approach to software development.
    • Improves project predictability, quality, and efficiency.
    • Reduces risks by setting clear requirements and early-stage planning.
    • Helps ensure timely delivery and alignment with end-user expectations.

    By following the SDLC phases, development teams can deliver high-quality software that meets functional requirements, is reliable and is maintainable over time.


    Factors Affecting Quality in System Development: Briefly describe these factors.

    Assignment of PMO (Principal of Management and Organization) - Technology369kk

     ** Assignment Of PMO ** Agenda: -  4 Questions discuss in this post. Question 1. Write a d etails note on selection why it Called. negative process.  Question 2. Write a details note on 'span of control. Question 3. Planning is an essential process, do you agree ? Discuss  Question 4. Write a note on management function. Q 1. Write a d etails note on selection why it called negative process.  Ans :-  Selection is the process of choosing the most suitable candidates out of the several candidates available.          Selection is a negative process because there may be more rejected then those selected in most of the candidates that is called selection is a negative process. → Selection process has the following steps:-  [ A .] Screening of applicants - Based on the screening of applicants only those candidates.
