Final answer:
A specification document for the Chocoholics Anonymous product using Gane and Sarsen's method involves creating data flow diagrams, developing data dictionaries, and ensuring that all elements are well documented and validated with stakeholders.
Step-by-step explanation:
Gane and Sarsen's Method for Chocoholics Anonymous Specification Document
To create a specification document using Gane and Sarsen's method for the Chocoholics Anonymous product described in the appendix, we need to follow a structured analysis approach. This involves identifying the data flow, creating data flow diagrams (DFDs), and developing data dictionaries.
Identify Data Flow
Start by understanding how data moves within the system. Identify inputs, processes, stores, and outputs related to the Chocoholics Anonymous product.
Create Data Flow Diagrams
Organize the information identified into a hierarchy of DFDs. You start with a context diagram that gives a high-level overview and then decompose into more detailed diagrams.
Develop Data Dictionaries
For each element within the DFDs, a data dictionary entry is created detailing the structure of data, type, and any relevant constraints.
Throughout this process, ensure that all project team members and stakeholders agree on the requirements and understand the proposed system design. Regular reviews and updates to the documentation are essential to reflect any changes or new insights.
Each step in this procedure should be well documented, with decisions and justifications made explicit. Continuous validation and verification with the client and team members helps confirm that the design meets the project's needs and constraints.
