Project management: how to correlate the schedule, costs, and decisions

Written by · Published on

Managing an investment requires a clear link between what needs to be delivered, the necessary activities, resources, and costs. A schedule without dependencies or a report with unjustified percentages does not show early enough where a delay occurs.

How do you define the project control baseline?

Break the project down into deliverables and work packages. For each one, establish the person responsible, acceptance criteria, inputs, and budget. Agree on the baseline for scope, schedule, and costs before monitoring.

Distinguish between a developed document and one that is verified, approved, or accepted. These statuses have different effects on subsequent stages and should not all be reported as "completed."

How is an integrated schedule built?

Link studies, design, permitting, procurement, execution, and commissioning through actual relationships. Include work calendars, site access, and client decisions. Check the critical path and time buffers, not just the displayed end date.

Updates must use verified achievements and remaining estimated durations. Maintain the baseline schedule and revision history to explain the effect of a change. Moving all activities to a new date loses information about the cause.

How do you correlate physical progress with costs?

Define measurement rules for packages: accepted quantities, verifiable stages, or deliverables. Do not assume that the invoiced percentage is equal to the physical percentage achieved. Separate commitments, invoices, payments, and the estimate of remaining costs.

A useful report compares actual progress against the plan and explains the deviation, the likely effect, and the necessary decision. For critical activities, highlight missing information and the deadline for its resolution to avoid bottlenecks.

How are changes and risks controlled?

Each change proposal must describe the reason, the impact on scope, schedule, cost, and operations. Identify necessary approvals and update the control baseline only after the decision is documented. Risks and issues that have already occurred are tracked separately.

For public investments, the documentary benchmarks from GD no. 907/2016 and contractual obligations must be integrated into the plan. If GD no. 1/2018 applies, the contractual circuit must be reflected separately from managerial reporting. A project manager does not automatically acquire the duties of the Supervisor or other regulated roles.

What information is needed for tendering?

Provide the project scope, contracts, current stage, budget, schedule, and list of participants. Specify whether the mandate covers design, execution, or the entire cycle, and which decisions the consultant can coordinate.

Deliverables may include the management plan, integrated schedule, risk and change logs, and periodic reports. Frequency and level of detail are set based on the project pace and client decisions, without redundant reporting.
