Documenting Findings of Requirements Analysis

Computer-Aided Software Engineering (CASE) tools are software applications designed to aid in various stages of the software development process, including requirements analysis. By utilizing CASE tools, an analyst can effectively document, manage, and communicate the findings of the requirements analysis phase, ensuring a comprehensive and consistent understanding of the system requirements among stakeholders. The following steps outline how an analyst can use CASE tools to document requirements analysis and findings:
  1. Requirements elicitation: CASE tools can support analysts in gathering and organizing information from various sources such as interviews, workshops, and questionnaires. These tools offer features for capturing and storing raw data, as well as functionalities to prioritize, categorize, and track the requirements.
  2. Requirements modeling: CASE tools provide graphical modeling capabilities to create visual representations of the requirements, such as Data Flow Diagrams (DFDs), Entity-Relationship Diagrams (ERDs), and Unified Modeling Language (UML) diagrams. These models help stakeholders gain a clear understanding of the system's structure, data flows, and relationships, facilitating communication and reducing the risk of misunderstandings.
  3. Requirements documentation: CASE tools often include built-in templates and document generation features to create a Requirements Specification Document, which outlines the functional and non-functional requirements, data requirements, business rules, and use cases. The tool ensures a consistent format and structure, improving the overall quality and readability of the document.
  4. Requirements traceability: With the help of CASE tools, analysts can establish and maintain a Requirements Traceability Matrix (RTM), which maps requirements to their corresponding design, development, and testing artifacts. The RTM enables analysts to track the progress of requirements throughout the project, manage changes, and assess the impact of modifications.
  5. Collaboration and communication: CASE tools often include features that facilitate collaboration among stakeholders, such as version control, change tracking, and commenting. These tools can integrate with project management and communication platforms, allowing team members to share and discuss requirements, models, and documents in a centralized location.
  6. Validation and verification: Analysts can use CASE tools to validate and verify the completeness, consistency, and accuracy of requirements. The tools may offer automated checks for syntax, semantics, and compliance with industry standards or best practices. Additionally, they can support the review and approval process by providing workflows and electronic signatures.

CASE tools play an essential role in supporting analysts during the requirements analysis phase. They enable efficient documentation, modeling, management, and communication of the findings, ensuring that the requirements are well-defined, accurate, and consistent. By leveraging the capabilities of CASE tools, analysts can improve the overall quality of the requirements analysis process and increase the likelihood of successful system development.

Notebook Computers with CASE tools

Question: Are you a database designer that carries a laptop computer with CASE tools installed to your assignments?
Many database designers have notebook computers with CASE tools installed, which they carry with them to assignments. This enables them, for example, to enter business objects, their relationships, and their characteristics directly into the CASE tool while analyzing the existing database(s). The tool then generates a draft entity-relationship (ER) diagram which is easily modified as more information is gleaned. The triangle of truth is a simple way to look at the important architectural constructs that make up a service oriented architecture. When you consider what is needed to build a service oriented architecture, the triad that makes up the triangle of truth quickly emerges. Specifically, there must be a way to represent the data that is exchanged between services, a mechanism for invoking services, and a way to compose services into a larger integrated business application.

(GIS) Geographic Information Systems

  1. Requirements analysis specifies what the the system is required to do based on user/stakeholder input
  2. Design specifies how the system will address the requirements
  3. Implementation translates design specifications into a working system
Requirements analysis is critical to the success of a project.
Requirements analysis can be applied at several different levels
  1. Overall system design
  2. Database design
  3. GIS application design
Determines data, information, system components, data processing and analysis functions required by an organization, enterprise, individual user.
