Study Notes

Understanding Analyst's Role

Analysts must comprehend how individuals think, learn, react to change, communicate, and work within various roles.
Analyzing human behavior is essential for effective decision-making and system implementation.

Terminology Matching Exercise

Designed to assist decision-makers in choosing options: DSS (Decision Support System)
Group responsible for determining information system requirements: System Analysts
Offers a generalized computing environment for senior managers: EIS (Executive Information System)
Involves hardware/software for data processing: Information Technology
Individuals using the system regularly: System Users
Facilitates flow of materials and information: Connections
Technical specialists translating business needs into solutions: System Designers
Collection of policies and procedures enabling organizational goals: Business System
Contains formatted data, text, images, and sounds: Information
Supports general office work: OAS (Office Automation System)

Pair Programming in XP

Pair programming involves two programmers collaborating on problem-solving, enhancing communication and productivity.
Benefits include higher-quality code and reinforcement of best practices like code-testing discipline.
Challenges include unstable requirements, lack of user conflict documentation, and absence of overall design specifications.

Unified Process (UP)

UP is an object-oriented system development methodology using UML for modeling.
Reinforces six best practices: iterative development, managing system requirements, component architecture usage, visual modeling, and quality control.
Four phases: Inception (scope & use cases), Elaboration (requirements iteration), Construction (building through iterations), Transition (deliver to users and training).

Traditional SDLC vs. UP Phases

UP phases do not rigidly define traditional analysis, design, and implementation blocks.
Phases focus on project team emphasis and discipline management, facilitating iterative development.

Requirements Planning in UP

Requirements planning involves determining application functionalities through user input.
User design phase includes active engagement discussing non-technical design aspects.
Construction phase involves using Rapid Application Development (RAD) tools to refine designs.
Cutover phase entails replacing old applications, user training, and adjusting organizational procedures.

When to Use RAD

RAD is beneficial when the development team has experience, and there are urgent business needs.
Useful for ecommerce applications aiming for a competitive edge and engaging users.

Advantages and Disadvantages of RAD

Advantages: Ideal for uncertain requirements, promotes active user engagement, increases project visibility, and allows early error detection.
Disadvantages about maintaining structured communication and potential project scope issues.

Work Breakdown Structure (WBS)

WBS helps accurately estimate project duration and effort, enhancing monitoring and control.
Different terminologies may be used across organizations to categorize WBS components.
Developing a WBS may require brainstorming sessions to ensure comprehensive task coverage.

PERT/CPM Diagram Overview

PERT (Program Evaluation and Review Technique) and CPM (Critical Path Method) merge for task scheduling visualization.
Tasks highlighted illustrate dependencies and the critical path, which must be monitored closely by project managers.
Rules for PERT/CPM include representation of each activity by branches and directional flow indication via arrows.

Effective Methods for Requirement Gathering

Common methods: reviewing existing reports, conducting interviews, observing business processes, distributing questionnaires, and participating in Joint Application Design (JAD) sessions.
Reviews of documentation can highlight discrepancies in business processes and identify existing best practices from external organizations.

Importance of Reviewing Existing Documentation

Examining internal and external documentation sources aids in understanding business rules and processes.
Effective for building preliminary understanding and developing interview questions for requirement gathering.
