Level Start Schedule Exercise:

Scenario:

A team of engineers is working on a complex oil & gas well construction project. The project involves several activities with varying durations and resource requirements. The project manager has decided to implement a Level Start Schedule to optimize resource allocation and ensure a smooth workflow.

Task:

1. Identify three activities with different durations and resource requirements from the project.
2. Create a simple Level Start Schedule for these three activities, considering resource availability and workload balance.
3. Explain how the Level Start Schedule helps to improve resource utilization and minimize potential bottlenecks in the project.

Techniques

Level Start Schedule: A Comprehensive Guide

Chapter 1: Techniques

Level start scheduling employs several techniques to achieve resource leveling. The core principle is to delay non-critical activities to smooth resource demand. This contrasts with early start scheduling, which prioritizes completing activities as early as possible regardless of resource impact. Key techniques include:

• Resource Smoothing: This focuses on minimizing resource fluctuations without increasing the project duration. It involves shifting activities within their float (the leeway an activity has before impacting the project end date) to create a more even resource profile.

• Resource Leveling Heuristics: These are rules-of-thumb used to determine which activities to delay. Common heuristics include delaying activities with the largest float, delaying activities with the least criticality, or delaying activities with the lowest resource cost. The choice of heuristic depends on the specific project priorities.

• Critical Chain Project Management (CCPM): While not strictly a level start scheduling technique, CCPM aligns well with the principles of resource leveling. By focusing on the critical chain (the longest sequence of dependent tasks), CCPM helps identify resource bottlenecks and allows for proactive mitigation through resource leveling strategies.

• Linear Programming: For complex projects, linear programming can be employed to mathematically optimize resource allocation. This technique considers all constraints and objectives to find the optimal solution for resource leveling. However, it requires significant computational power and expertise.

Chapter 2: Models

Several models support level start scheduling, ranging from simple spreadsheet-based approaches to sophisticated software simulations.

• Spreadsheet Models: Simple projects can be managed using spreadsheets to track resource assignments and activity durations. This allows for manual adjustment of activity start times to achieve a more level resource profile. However, this approach becomes unwieldy for larger, more complex projects.

• Gantt Charts: While primarily visualizing project schedules, Gantt charts can be adapted to show resource allocation and aid in identifying potential resource conflicts. Manually adjusting activity start times on a Gantt chart can facilitate resource leveling.

• Simulation Models: For complex projects with uncertain durations and resource availability, simulation models are useful. These models can simulate various scenarios and help assess the impact of different resource leveling strategies on project outcomes. Monte Carlo simulation is particularly well-suited for this task.

• Network Diagrams (Precedence Diagramming Method): These diagrams visually represent the dependencies between activities. Analyzing the network diagram alongside resource availability data facilitates identifying potential bottlenecks and informing resource leveling decisions.

Chapter 3: Software

Various software packages offer tools to assist with level start scheduling. These range from simple project management tools to specialized resource management software.

• Microsoft Project: This widely-used project management software includes features for resource allocation and leveling. While it primarily uses a critical path approach, manual adjustments can be made to achieve a level start schedule.

• Primavera P6: A more sophisticated project management software package commonly used in large-scale projects like those in the oil and gas industry. Primavera P6 offers advanced features for resource leveling and optimization.

• Resource Management Software: Dedicated resource management software provides more specialized tools for resource allocation and leveling. These often incorporate features such as resource forecasting, demand planning, and what-if analysis. Examples include some enterprise resource planning (ERP) systems.

• Custom Software Solutions: For highly specific needs or complex projects, custom software solutions might be developed to optimize resource leveling based on specific project constraints.

Chapter 4: Best Practices

Effective implementation of level start scheduling requires adherence to several best practices:

• Accurate Data: Accurate data on resource availability, activity durations, and dependencies is crucial. Inaccurate data will lead to ineffective leveling and potential project delays.

• Collaboration: Involving relevant stakeholders (engineers, technicians, managers) in the scheduling process ensures buy-in and accurate reflection of resource constraints.

• Iterative Process: Resource leveling is often an iterative process. Initial leveling attempts may reveal further conflicts or imbalances, requiring adjustments and refinement.

• Regular Monitoring: Continuous monitoring of resource allocation and schedule progress allows for proactive identification and mitigation of potential problems.

• Flexibility: The schedule should be flexible enough to accommodate unforeseen events or changes in resource availability. Contingency plans should be in place to address potential disruptions.
