Linked Bar Chart Exercise:

Scenario: Imagine you are managing an oil and gas exploration project. You are about to create a Linked Bar Chart for the project.

Task:
1. Identify 5 key activities or tasks that need to be completed in your project. 2. Determine the dependencies between these tasks (e.g., which tasks must be finished before others can start). 3. Create a simple diagram or flowchart representing the tasks and their dependencies. This does not have to be a fully detailed Linked Bar Chart, but it should show the connections between the tasks.

Example:

Task 1: Seismic Survey Task 2: Well Permit Application Task 3: Drilling Rig Mobilization Task 4: Exploratory Drilling Task 5: Data Analysis

Dependency: - Task 2 must be completed before Task 3 can begin. - Task 4 depends on both Task 2 and Task 3 being finished.

Techniques

Chapter 1: Techniques

Linked Bar Chart Techniques: A Visual Guide to Project Dependencies

The Linked Bar Chart is a powerful tool for visualizing project dependencies, but its effectiveness depends on the techniques used to create and interpret it. This chapter delves into key techniques that maximize the value of Linked Bar Charts:

1. Activity Definition and Sequencing:

• Clearly Define Tasks: Ensure each bar represents a specific, measurable task with a defined start and end date.
• Logical Sequencing: Arrange tasks in a logical order based on their dependencies. Tasks that must be completed before others should appear earlier on the chart.
• Avoid Overlap: Ensure bars do not overlap to prevent confusion and maintain clarity.

2. Dependency Representation:

• Arrows and Connectors: Use arrows to visually connect dependent tasks. The direction of the arrow indicates the flow of dependency (e.g., task A must be completed before task B).
• Different Arrow Styles: Consider using different arrow styles or colors to represent different types of dependencies (e.g., finish-to-start, start-to-start).

3. Time Scale and Duration:

• Appropriate Scale: Choose a time scale that accommodates the project's overall duration while providing sufficient detail for individual tasks.
• Accurate Durations: Ensure the bar lengths accurately reflect the estimated duration of each task.

4. Resource Allocation and Constraints:

• Color Coding: Use colors to represent different resources or teams responsible for each task. This can help identify potential resource conflicts.
• Constraint Markers: Utilize symbols or markers to indicate constraints or limitations (e.g., deadlines, external factors) affecting tasks.

5. Data Integration and Updates:

• Data Source Integration: Link the Linked Bar Chart to project management software or spreadsheets to enable real-time data updates and ensure accuracy.
• Regular Updates: Update the chart regularly to reflect progress and any changes in dependencies or timelines.

6. Critical Path Analysis:

• Critical Path Identification: Use the Linked Bar Chart to identify the critical path, the sequence of tasks with the longest total duration. This highlights the most crucial tasks that impact project completion.
• Float Calculation: Calculate the float (or slack) for each task, representing the amount of time it can be delayed without affecting the project deadline.

By mastering these techniques, you can create Linked Bar Charts that effectively convey project dependencies and facilitate informed decision-making.

Chapter 2: Models

Linked Bar Chart Models: Adapting the Tool for Different Oil & Gas Scenarios

While the core concept of a Linked Bar Chart remains constant, different models can be tailored to specific oil and gas project scenarios:

1. Project Lifecycle Model:

• Exploration & Appraisal: Focus on sequential dependencies between geological surveys, drilling operations, well testing, and data analysis.
• Field Development: Illustrate the intricate relationships between construction, installation, commissioning, and initial production phases.
• Production & Operations: Depict dependencies for maintenance schedules, well interventions, and production optimization activities.
• Decommissioning & Abandonment: Show the sequential dismantling, removal, and site restoration activities.

2. Functional Breakdown Model:

• Engineering: Represent the dependencies between design, engineering, and procurement activities.
• Construction: Visualize the relationships between site preparation, construction, and installation phases.
• Operations: Depict the dependencies between production, maintenance, and safety operations.

3. Resource-Based Model:

• Equipment Availability: Illustrate the availability and scheduling of critical equipment, such as drilling rigs or production platforms.
• Personnel Deployment: Represent the allocation and movement of personnel across different project phases.
• Material Procurement: Visualize the procurement timeline and dependencies for essential materials and components.

4. Risk Management Model:

• Risk Mitigation Activities: Connect risk mitigation activities to their respective tasks, showing how proactive measures address potential issues.
• Contingency Planning: Illustrate the dependencies between contingency plans and their activation conditions, ensuring timely response to unforeseen events.

By selecting the appropriate model, you can ensure the Linked Bar Chart effectively addresses the specific requirements and complexities of your oil and gas project.
