4. Project Integration Management (4)

4.4 Monitor and Control Project Work
Monitor and Control Project Work is the process of tracking, reviewing, and reporting the process to meet the performance objectives defined in the project management plan.



Monitor and Control Project Work process is concerned with

  • comparing actual project performance against the project management plan
  • assessing performance to determine whether any corrective or preventive actions are indicated, and then recommending those actions as necessary
  • identifying new risks and analyzing, tracking, and monitoring existing project risks to make sure the risks are identified, their status is reported, and that appropriate risk response plans are being executed
  • maintaining an accurate, timely information base concerning the project's products and their associated document through project completion
  • providing information to support status reporting, progress measurement, and forecasting
  • providing forecasts to update current cost and current schedule information
  • monitoring implementation of approved changes as they occur
  • providing appropriate reporting on project progress and status to program management when the project is part of an overall program

Inputs
1) Project management plan: monitoring and controlling project work involves looking at all aspects of the project, subsidiary plans (Scope, requirements, schedule, cost, quality, etc.) within the project management plan form the basis for controlling the project

2) Schedule forecasts: forecasts are derived from progress against the schedule baseline and computed time estimate to complete (ETC). Forecasts are typically expressed in terms of schedule variance (SV) and schedule performance index (SPI).

3) Cost forecasts: forecasts are derived from progress against the cost baseline and computed cost estimates to complete (ETC). Expressed in terms of cost variance (CV) and cost performance index (CPI). An estimate at completion (EAC) can be compared to the budget at completion (BAC) to see if the project is still within tolerance ranges or if a change request is required.

4) Validated changes: approved changes that results from the Perform Integrated Change Control process require validation to ensure that the change was appropriately implemented. A validated change provides the necessary data to confirm that the change was appropriately executed.

5) Work Performance Information: performance data collected from various controlling processes, analyzed in context, and integrated based on relationships across areas. Work performance information (e.g. status of deliverables, implementation status for change requests, forecasts) is circulated through communication processes.

Tools and Techniques
2) Analytical techniques: applied in project management to forecast potential outcomes based on possible variations of project or environmental variables and their relationships with other variables.
- Regression analysis
- Grouping methods
- Causal/Root cause analysis
- Forecasting methods (e.g. time series, scenario building, simulation)
- Failure mode and effect analysis (FMEA)
- Fault tree analysis (FTA)
- Reserve/Trend/Variance analysis
- Earned value management (EVM)

Outputs
1) Change requests: as a result of comparing planned results to actual results, change requests may be issued to expand, adjust, or reduce project scope, product scope, or quality requirements and schedule or cost baselines. Change requests may necessitate the collection and documentation of new requirements. Changes can impact the project management plan, project documents or product deliverables. Changes that meet the project's change control criteria should go through the integrated change control process established for the project. Changes may include corrective, preventive actions and defect repair.

2) Work performance reports: physical or electronic representation of work performance information compiled in project documents, intended to generate decisions, actions, or awareness.

3) Project management plan updates: changes identified during the Monitor and control project work process may affect the overall project management plan. These changes, after being processed through the appropriate change control process can lead to project management plan updates.

4) Project documents updates: documents such as schedule and cost forecasts, work performance report, issue log, may be updated.
