Week 4 Mini-Case
Colonial Movers
Task 1
: Involvement of Employees
Question: Should employees be involved in developing the new system? If so, what should be
their role?
Response: Employees should be involved in the development of the new system. Their role
could include providing insights into daily operations, identifying pain points, and suggesting
improvements based on their experience. This involvement ensures that the system meets the
practical needs of the users, enhancing user adoption and overall system success.
Task 2
: System Requirements
Question: What types of system requirements will you focus on? Explain each one in detail.
Response: System requirements can include:
Functional Requirements: Describing the specific functions the system must perform, such as
order processing, inventory management, and customer communication.
Non-functional Requirements: Covering aspects like system performance, security, and usability.
Data Requirements: Detailing the data the system needs to store, process, and report.
Integration Requirements: Outlining how the new system will integrate with existing systems.
User Requirements: Defining the expectations and preferences of end-users.
Task 3
: JAD Sessions Plan
Question: You decide to conduct a series of JAD sessions. Prepare a memo to participants and
include a detailed plan.
Response: The memo should include:
Introduction to JAD and its purpose.
Schedule and agenda for each session.
List of participants and their roles.
Materials needed for the sessions.
Overview of expected outcomes.
Encouragement for active participation.
Task 4
: Fact-Finding Methods
Question: What fact-finding methods could you use to collect information from employees at
Colonial Movers? Suggest at least three methods and explain the pros and cons of each.
Response:
Interviews:
Pros: Direct interaction allows for in-depth exploration. Clarification can be sought in real-time.
Cons: Time-consuming, may be influenced by interviewer bias.
Surveys/Questionnaires:
Pros: Efficient for gathering information from many employees. Anonymity may encourage
honest feedback.
Cons: Limited depth, potential for incomplete or vague responses.
Observation:
Pros: Provides a firsthand view of actual processes and challenges.
Cons: May not capture all relevant information, and employees may alter behavior when being
observed.
By addressing these tasks, you can create a comprehensive plan for involving employees,
defining system requirements, conducting JAD sessions, and selecting appropriate fact-finding
methods for information collection.

Task 1
: Use of Feature-Driven Development (FDD) in Requirements Modeling
Question: Explain how an FDD can be used in requirements modeling.
Response: FDD can be employed in requirements modeling by breaking down the system into
small, manageable features. Each feature represents a piece of functionality that can be
developed, tested, and delivered independently. This approach helps in prioritizing and detailing
specific features based on user needs, ensuring a more focused and iterative development
process. FDD emphasizes collaboration between developers and users to define and refine
features, fostering a clear understanding of requirements throughout the development lifecycle.
Task 2:
Business Process Modeling (BPM)
Question: Describe BPM and how it can be used.
Response: BPM involves the visual representation of business processes to understand, analyze,
and improve them. It can be used in the new marketing system development by:
Identifying and mapping current marketing processes.
Analyzing process inefficiencies and bottlenecks.
Designing optimized processes for the new system.
Providing a visual guide for stakeholders to understand and validate the proposed changes.
Task 3
: Use of Data Flow Diagrams (DFDs) in Requirements Modeling
Question: Explain how DFDs can be used in requirements modeling.
Response: DFDs are used to represent the flow of data within a system. In requirements
modeling, DFDs help by:
Identifying data sources, processes, data storage, and data destinations.
Illustrating how data moves through the system.
Defining the inputs and outputs of each process.
Providing a high-level overview of system functionality, aiding in the identification of
requirements and potential areas for improvement.
Task 4
: Unified Modeling Language (UML) in Systems Development
Question: Describe the UML and how it can be used during systems development.
Response: UML is a standardized visual modeling language used for system design and
documentation. It can be employed in systems development by:
Providing various diagrams (e.g., use case diagrams, class diagrams, sequence diagrams) to
represent different aspects of the system.
Enhancing communication between developers, managers, and users through a common visual
language.
Offering a blueprint for system architecture, behavior, and interactions.
Facilitating a more comprehensive understanding of the system's structure and functionality.
By addressing these tasks, you can effectively communicate the relevance and utilization of FDD,
BPM, DFDs, and UML in the development of the new marketing system to the managers and
users on the systems development team.
