b) The objectives of monitoring and controlling in project management are:
Tracking Progress: Monitoring and controlling aim to track the progress of a project and ensure that it is on schedule and within budget. It involves regularly reviewing and comparing actual project performance against planned performance to identify any variances or deviations.

Identifying and Managing Risks: Monitoring and controlling help identify potential risks and issues in a project. By actively monitoring project activities, a project manager can detect early warning signs and take proactive measures to mitigate risks and prevent them from escalating.

Quality Assurance: Monitoring and controlling involve ensuring that the project is meeting the required quality standards. It includes conducting inspections, reviews, and tests to verify that deliverables and project outcomes meet the specified quality criteria.

Scope Management: Monitoring and controlling help in managing the project scope. It involves reviewing and controlling changes to the project scope, ensuring that any modifications are properly assessed, approved, and integrated into the project plan.

Resource Allocation: Effective monitoring and controlling enable project managers to track resource utilization and ensure that resources are allocated efficiently. It involves identifying resource bottlenecks, resolving conflicts, and making adjustments to optimize resource allocation.

Stakeholder Management: Monitoring and controlling activities also involve engaging with stakeholders and managing their expectations. Project managers need to communicate progress, address concerns, and involve stakeholders in decision-making processes to maintain stakeholder satisfaction and support.

SOLUTION
a) Identify all the external entities, processes, data stores and data flows

a) Based on the provided scenario, we can identify the following external entities, processes, data stores, and data flows:

External Entities:

  1. Buses: The buses that come to the garage for repairs.
  2. Mechanic: The person responsible for performing the repairs.
  3. Helper: Assists the mechanic in performing the repairs.
  4. Accounting Department: Utilizes repair information for billing purposes.
  5. Inventory Management Computer System: Monitors parts used for repairs.
  6. Supervisor: Reviews the performance of the mechanic and helper.

Processes:

  1. Repairs: The process of repairing the buses.
  2. Record Reason for Repair: The process of documenting the reason behind each repair.
  3. Record Total Cost: The process of recording the total cost of parts used for repairs.
  4. Billing: The process carried out by the Accounting Department for generating invoices.
  5. Parts Monitoring: The process performed by the inventory management computer system to track parts usage.
  6. Performance Review: The process conducted by the supervisor to evaluate the performance of the mechanic and helper.

Data Stores:

  1. Shop Repair Order: Stores information about the repairs, including the reason for repair and total cost of parts.

Data Flows:

  1. Repair Information: Flows from the Buses to the Repairs process, Shop Repair Order, and Supervisor for performance review.
  2. Reason for Repair: Flows from the Repairs process to the Shop Repair Order.
  3. Total Cost of Parts: Flows from the Repairs process to the Shop Repair Order and Accounting Department.
  4. Billing Information: Flows from the Shop Repair Order to the Billing process and Accounting Department.
  5. Parts Usage Information: Flows from the Shop Repair Order to the Parts Monitoring process and Inventory Management Computer System.
  6. Performance Review Information: Flows from the Shop Repair Order to the Performance Review process and Supervisor.

b) The context diagram for the above scenario is a high-level overview that shows the interactions between the system and external entities. Here is a simplified representation of the context diagram:
