Study Notes

Time-Constrained vs. Resource-Constrained Projects

Time-Constrained Projects: Completion time is fixed; resources are adjusted to meet deadlines.
Example: Product launch on a specific date.
Resource-Constrained Projects: Limited resources; completion time varies based on resource availability.
Example: Building construction with limited labor.

Implications

Time-constrained environments: Focus on accelerating work, often by allocating additional resources, which can increase costs.
Resource-constrained environments: Prioritization is crucial; it often causes delays but maintains cost control. This may require resource leveling/smoothing.

Resource Leveling/Smoothing

Definition: Adjusting project schedules to address resource constraints and balance resource usage.
Purpose: Prevent over-allocation or under-utilization of resources.
Use Case: Projects with limited resources or needing consistent workloads.

Heuristics in Resource-Constrained Projects

Definition: Simple, quick, practical decision-making methods requiring less computational effort than optimization models.
Usefulness: Useful for complex problems with limited information, providing satisfactory solutions within reasonable time limits.

Three Rules of Thumb (Heuristics) for Scarce Resources

First Come, First Serve: Allocate resources based on task arrival order.
Shortest Task First: Prioritize tasks with shorter durations.
Critical Path First: Focus resources on tasks on the critical path to minimize delays.

Four Common Elements of a Project Plan

Project Objectives: Clear project goals and desired outcomes.
Work Breakdown Structure (WBS): Dividing the project into manageable tasks.
Schedule: Timelines for tasks and project milestones.
Budget: Allocation of financial resources for tasks and the overall project.

Project Initiation Process

Key Steps: Defining objectives, stakeholder identification, project charter creation, and resource allocation.
Project Charter: Outlines project purpose, objectives, stakeholders, and authorization.
Stakeholder Engagement: Aligns all relevant parties with project goals.

Project Scope Statement and Scope Creep

Scope Creep: Uncontrolled changes or extensions to a project's scope without proper approval.
Scope Statement: Detailed description of deliverables, objectives, boundaries, and exclusions; minimizes scope creep.

Work Breakdown Structure (WBS)

Purpose: Organizes the project, improves resource allocation, enhances communication, facilitates progress tracking, minimizes risks.

Earned Value Management (EVM)

Definition: Project management technique comparing planned work with completed work and costs.
Key Measures: Planned Value (PV), Earned Value (EV), Actual Cost (AC).

Project Risk Sources (South Africa)

Economic Instability: Fluctuations in currency exchange, inflation, and financial crises.
Political Factors: Policy changes, strikes, and social unrest.
Resource Constraints: Limited availability of skilled labor, raw materials, or equipment.
Infrastructure Challenges: Power outages, transportation delays, or unreliable communication networks.

Contingency Reserve vs. Budget Reserve vs. Management Reserve

Contingency Reserve: Set aside for known risks during planning.
Budget Reserve: For unforeseen project costs.
Management Reserve: For high-level, unknown risks affecting the entire project.

Ethical Challenges in Project Execution

Honesty in Reporting: Accurate progress and cost reporting without misrepresentation.
Fair Treatment: No discrimination or favoritism in resource allocation.
Conflict of Interest: Avoiding personal interests influencing professional decisions.
