Estimate Costs

The effort to produce a realistic estimate of the funds required to finish all project work.

Key Points

  • Calculates expected costs for activities, resources, and procurements, including direct, indirect, and reserve amounts.
  • Uses methods such as analogous, parametric, bottom-up, three-point estimating, and vendor bid analysis.
  • Produces cost estimates and the basis of estimates; may update assumptions, risks, and resource information.
  • Feeds the Determine Budget process and funding needs; estimates are refined as more data becomes available.

Example

A project manager for a software rollout estimates developer effort, software licenses, cloud hosting, training, and travel. They apply a parametric rate per story point, gather vendor quotes for licenses, and add contingency reserves for integration risks. The resulting figures are used later to build the cost baseline.

PMP Example Question

During planning, a PM quantifies the likely costs for labor, materials, equipment, and includes contingency for identified risks. Which process is being performed?

  1. Plan Cost Management
  2. Estimate Costs
  3. Determine Budget
  4. Control Costs

Correct Answer: B — Estimate Costs (estimating the funds needed to complete the work)

Explanation: Estimate Costs focuses on forecasting the monetary resources for project work; Determine Budget aggregates those estimates into an authorized cost baseline.

ICS/OT Cybersecurity Fundamentals — Security Built for Industrial Systems

Industrial control systems cannot be secured like ordinary IT. A forced reboot, aggressive scan, or incompatible patch can interrupt production and create real safety consequences. Effective OT security begins with understanding the systems, constraints, and risks unique to industrial environments.

This course gives IT professionals, engineers, operators, and security practitioners a practical foundation in ICS threats, zone and conduit design, risk assessment, passive asset visibility, and vendor evaluation. You will learn how IEC 62443, NIST CSF, and MITRE ATT&CK for ICS apply where availability and safety come first.

Eight reconstructed incidents—including Stuxnet, Triton, Ukraine 2015, Colonial Pipeline, and PIPEDREAM—show how attackers move through OT environments, what they target, and which defenses could have changed the outcome.

Watch the course preview, then build the vocabulary, frameworks, and judgment needed to take credible first steps in ICS/OT cybersecurity.

Build an ICS/OT cybersecurity foundation that fits the real environment

Standard IT controls can disrupt the industrial systems they are meant to protect. Learn how to assess OT risk, design zones and conduits, apply IEC 62443 security levels, use MITRE ATT&CK for ICS, and establish passive asset visibility without risking production. Eight reconstructed incidents connect attacker techniques to the controls that failed, giving you the vocabulary and judgment to make credible security decisions from day one.
