As a System Analyst tasked with creating comprehensive documentation for an Automated Systemwithin a selected organization, you are responsible for initiating user requirement gathering andsystem environment analysis. You have the flexibility to choose an organization or continue witha hypothetical organization. To facilitate the commencement of system investigation activities, itis imperative to obtain proper approval from authorized officials of the companies being visited.To secure approval, you are required to submit an official request letter from ICBT Campus to therespective company. The letter should articulate the purpose of the visit and seek authorization forconducting interviews and site observations as part of the initial stages of the project.Tasks1. You are required to select a organization and provide clear introduction about theorganization and then conduct an organizational analysis and use appropriate fact gatheringtechniques for gather system requirement of a client (25 Marks)2. Identify the advantage of using a standard software development lifecycle a model fordeveloping the software solution what is proposed for the organization/ institution.(15 Marks)3. Design the data model of the software solution that will be implemented in theorganization by considering all required data / information requirements and explain brieflywhat is the best technique is to carry out data model designing of the system. (25 Marks)4. Design the functional model of the system software solution that will be implemented inthe organization having concerned all the features /facilities, data collection, transitions,transfers and dissemination requirements and explain briefly what is the best technique isto carry out functional model designing of the system. (35 Marks)

To begin, I would select an organization, for example, a retail company. This company could be a large-scale business that has multiple branches across the country. The organization's main operations include purchasing goods from suppliers, managing inventory, and selling products to customers. To conduct an organizational analysis, I would use fact-gathering techniques such as interviews, observations, and document analysis. Interviews would involve speaking to key stakeholders in the organization to understand their needs and challenges. Observations would involve visiting the organization's premises to understand their operations and processes. Document analysis would involve reviewing existing documentation such as process manuals, system documentation, and organizational charts.

Using a standard software development lifecycle model has several advantages. It provides a structured approach to software development, ensuring that all necessary steps are followed. This can lead to higher quality software and can reduce the risk of project failure. It also facilitates communication and understanding among team members as everyone is following the same process. Furthermore, it can make planning and estimating more accurate as each phase of the lifecycle has defined inputs, outputs, and activities.

To design the data model of the software solution, I would first identify all the required data elements. This could include data about suppliers, products, inventory, sales, and customers. I would then define the relationships between these data elements and organize them into tables or entities. The best technique for carrying out data model designing is Entity-Relationship (ER) modeling. This technique allows for easy visualization of data and their relationships, making it easier to understand and communicate the data model.

To design the functional model of the system software solution, I would first identify all the features and facilities required by the organization. This could include inventory management, sales processing, and customer relationship management. I would then define the data collection, transitions, transfers, and dissemination requirements for each feature. The best technique for carrying out functional model designing is using Use Case diagrams. This technique allows for easy visualization of system functions and their interactions with users, making it easier to understand and communicate the functional model.

To begin, I would select an organization, for instance, a retail company. This organization is a multi-branch entity that deals with a variety of products, from groceries to electronics. The organizational analysis would involve understanding the structure of the organization, its operations, and its current systems. Fact-gathering techniques such as interviews, observations, and document analysis would be used to gather system requirements. Interviews would involve speaking to various stakeholders like managers, employees, and customers to understand their needs and expectations from the system. Observations would involve understanding the current processes and identifying areas of improvement. Document analysis would involve studying existing documentation of processes and systems.

Using a standard software development lifecycle model has several advantages. It provides a structured approach to software development, ensuring that all necessary steps are followed. This reduces the risk of missing important aspects of development. It also allows for better planning and management of the project, as each phase has specific deliverables and timelines. Furthermore, it facilitates communication and understanding among team members as everyone is aware of the process and expectations.

The data model would be designed based on the information requirements identified during the requirement gathering phase. It would include all necessary data entities, their attributes, and relationships. The best technique for data model designing is Entity-Relationship (ER) modeling. It is a graphical approach that allows for easy visualization and understanding of the data requirements.

The functional model would be designed considering all the features and facilities required by the organization. It would detail how data is collected, processed, stored, and disseminated. The best technique for functional model designing is the use of Data Flow Diagrams (DFD). DFDs provide a graphical representation of the system, showing how data flows through it and how it is transformed. This makes it easier to understand the system's functionality and identify potential issues.
