7.5 Control Schedule
Inputs Tools & Techniques Outputs

Replace this with term.

Purpose & When to Use

  • Confirm work is proceeding on time by comparing actuals to the approved schedule baseline.
  • Detect slippage early, understand causes, and decide on corrective or preventive actions.
  • Forecast key dates and completion, keeping stakeholders informed with reliable schedule information.
  • Use throughout the project, especially at reporting cycles, milestones, major deliveries, or when risks or changes affect timing.

Mini Flow (How It’s Done)

  • Gather actual progress: starts, finishes, percent complete, remaining duration, and impediments.
  • Update the schedule model in the PMIS with the latest actuals and confirmed logic, calendars, and resources.
  • Compare to the baseline using variance and trend analysis, critical path review, and metrics such as SV and SPI if using EVM.
  • Identify root causes and impacts, focusing on critical and near-critical paths, resource constraints, and external dependencies.
  • Forecast new dates by recalculating the network, re-estimating remaining work, and assessing risks to the timeline.
  • Select and apply responses: resequence work, adjust resources, fast-track, crash, or implement preventive actions; raise change requests if the baseline must change.
  • Communicate updates via schedule reports and dashboards, and update logs, risks, assumptions, and lessons as needed.

Quality & Acceptance Checklist

  • Actuals are current, traceable to evidence such as timesheets or system data, and use a consistent data date.
  • Critical and near-critical paths are recalculated after each update, with total float reviewed.
  • No open-ended activities exist; start and finish constraints and lags are justified and documented.
  • Calendars and resource availability are correctly applied to durations and forecasts.
  • Progress measurement rules are consistent across activities, including how percent complete is determined.
  • Variance thresholds are defined, and actions are triggered when thresholds are exceeded.
  • Schedule forecasts and reports match the PMIS output, and stakeholders receive updates appropriate to their needs.
  • Baseline changes follow formal change control; no unauthorized rebaselining occurs.

Common Mistakes & Exam Traps

  • Rebaselining to hide variance instead of first applying corrective or preventive actions.
  • Ignoring near-critical paths that may overtake the critical path after changes.
  • Choosing fast-tracking or crashing without analyzing risks, costs, and resource limits.
  • Confusing calendar days with working days, leading to incorrect finish forecasts.
  • Relying only on percent complete instead of re-estimating remaining duration and recalculating the schedule.
  • Applying changes to leads, lags, or constraints without documenting and controlling them.
  • Using SPI at project end to judge schedule health when it naturally trends to 1.0; focus on remaining work and path analysis.

PMP Example Question

A project is two weeks behind schedule, but the sponsor wants to keep the original completion date. What should the project manager do first?

  1. Submit a change request to rebaseline the schedule to the new forecast.
  2. Add resources to all late activities to recover time.
  3. Fast-track the entire project by running as many tasks in parallel as possible.
  4. Analyze the critical and near-critical paths to identify targeted fast-tracking or crashing options and their risks.

Correct Answer: D — Analyze the critical and near-critical paths to identify targeted fast-tracking or crashing options and their risks.

Explanation: Evaluate schedule drivers before choosing a response. Do not rebaseline or add resources broadly without focused analysis and risk assessment.
