Generate Project Schedule Templates

This skill creates comprehensive project schedules and templates using work breakdown structures (decomposing a project into 8-80 hour work packages with hierarchical numbering and 100% scope coverage), dependency management across the four standard relationship types (Finish-to-Start being most common, plus Start-to-Start, Finish-to-Finish, and rare Start-to-Finish), and three-point duration estimation - (Optimistic + 4x Most Likely + Pessimistic) / 6 - that accounts for resource availability and adds buffer time for high-risk activities.

It structures schedules around five standard phases with typical duration shares - Initiation (5-10%), Planning (15-25%), Execution (50-70%), ongoing Monitoring & Control, and Closure (5-10%) - each broken into named sub-activities. Resource allocation guidance covers four resource categories (human, equipment, materials, facilities) with rules capping critical resources at 80% allocated capacity, reserving a 20% buffer for unplanned work, and accounting for holidays, training, and new-team-member ramp-up. Critical path analysis covers identifying the longest chain of dependent tasks, calculating early/late start and finish dates, determining float for non-critical activities, and monitoring the critical path daily, alongside Gantt chart and milestone template formats for visualizing the schedule.

Risk and buffer management defines three buffer types - a project buffer (15-25% at the project end), feeding buffers (10-15% where non-critical chains feed the critical path), and resource buffers - with buffer size and monitoring frequency scaled to risk level (5-10% and weekly monitoring for low risk, up to 30-50% and real-time monitoring for high risk). Best practices cover adapting templates to industry standards (PMBOK, PRINCE2, Agile), maintaining schedules (weekly updates, rebaselining when scope changes exceed 10%, version control), and communication (red/yellow/green status indicators, variance analysis). Advanced techniques cover resource leveling to eliminate over-allocation, mapping Agile epics and sprints onto project phases with velocity-based estimates, and earned value metrics (Planned Value, Earned Value, Schedule Performance Index).

Use this skill when building a project schedule from scratch or adapting one to a specific methodology - defining a work breakdown structure, estimating task durations, mapping dependencies and critical path, allocating resources, or sizing risk buffers.

It is not a fit for project scope or requirements definition itself - it assumes the work packages and deliverables are already defined and focuses on sequencing, estimating, and resourcing them into a schedule.

Inputs are the project's work breakdown structure, task dependencies, resource availability, and risk profile. Outputs are a phased schedule with duration estimates, a Gantt chart or milestone template, critical path analysis with float calculations, resource allocation with buffers, and risk-adjusted buffer sizing with a monitoring cadence.

Project managers building or maintaining detailed schedules who need concrete formulas and templates - three-point duration estimation, critical path float calculation, resource leveling, and risk-scaled buffer sizing - adaptable to PMBOK, PRINCE2, or Agile-hybrid delivery models, rather than building scheduling logic from scratch each time.
