Project management entails intricate processes involving planning, scheduling, resource allocation, and risk management to ensure project success. An essential component of effective project planning is developing an activity network diagram, which illustrates the sequence of activities, their dependencies, durations, and critical deadlines. By accurately modeling these elements, project managers can visualize workflow, identify bottlenecks, and facilitate decision-making related to project scope, timing, and resource utilization.

The first step in this process involves constructing a detailed activity network diagram based on the data provided. Activities A through H have specified predecessors and durations, demanding precise placement within a directed graph that reflects dependencies such as activity B contingent upon activity A, activity D dependent on B and C, and so forth. Utilizing specialized software like Microsoft Excel or project management tools allows for the dragging and positioning of activities to reflect their logical sequences accurately. This visual representation serves as the foundation for subsequent calculations related to project timing and critical path determination.

Once the network diagram is established, the next vital task is performing a critical path analysis via forward and backward passes. The forward pass calculates the earliest start (ES) and earliest finish (EF) times for each activity, considering the project's minimum duration. Conversely, the backward pass assesses the latest start (LS) and latest finish (LF) dates, respecting project deadlines and float times. The intersection of activities with zero float identifies the critical path—the sequence of activities dictating the overall project duration. For instance, in this scenario, the critical path might include activities such as A, B, D, F, and H, or other defined sequences based on the calculations. Determining the longest project duration pinpoints areas where delays could extend delivery timelines, making these activities critical points of focus for schedule control.

Project crashing presents an opportunity to reduce project duration by expediting specific activities, typically at increased costs. Analyzing precrash and postcrash durations and associated costs offers insights into the most cost-effective activities to crash. Calculating the per-day crash cost involves dividing the additional crashing cost by the reduction in activity duration. For each activity, this metric guides prioritization for crashing efforts, identifying the most attractive candidates—those that provide the greatest time reduction per dollar invested. The most and second most attractive activities are selected based on the lowest per-day crash costs, while the least attractive are avoided due to unfavorable cost-benefit ratios.

Resource loading analysis examines the allocation of resources across project activities to ensure that demand does not exceed capacity. Given a maximum of eight resource hours available per day, the resource-loading chart reveals days when resource demand surpasses this limit, indicating overallocation. Such conflicts can be addressed by re-scheduling activities, adjusting durations, or reallocating tasks to balance resource utilization effectively. Proper reconfiguration minimizes idle times, prevents burnout, and maintains stakeholder confidence by keeping the project within scope, time, and resource constraints.

Integrating these elements—diagram creation, critical path analysis, crashing strategies, and resource management—provides a comprehensive framework for effective project execution. By systematically applying these techniques, project managers can optimize schedules, manage risks, and ensure timely delivery of project objectives, ultimately contributing to organizational success and stakeholder satisfaction.
