Project Timescales

Timescales describe how long the project will run. When connected to the business case, they also include the period during which the project's benefits are expected to be realized.

Key Points

  • Expresses the total project duration from start to finish.
  • Includes the benefits realization horizon tied to the business case.
  • Anchored by milestones and release dates; refined as plans evolve.
  • Influenced by constraints, dependencies, and delivery cadence (e.g., sprints, releases).

Example

A team plans a 6-month implementation for a new CRM, with benefits (higher sales conversion and reduced service time) expected to accrue over the following 24 months. The project timescale is 6 months, while the business-case timescale extends 2 years for benefits realization.

PMP Example Question

Which statement best describes project timescales when linked to the business case?

  1. They only cover activity durations and internal milestones during execution.
  2. They define the approved budget and cost reserves for the project.
  3. They include both the project duration and the period over which benefits are realized.
  4. They specify the staffing plan and team ramp-up timeline.

Correct Answer: C — project duration plus benefits realization period

Explanation: Timescales reflect how long the project takes and, for the business case, also the timeframe in which benefits are expected to materialize.

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.
