Iterative Life Cycle

A way of working where incomplete deliverables are created in cycles, reviewed early, and refined based on feedback until the result meets expectations.

Key Points

  • Produces partial versions of the product in repeated iterations.
  • Seeks stakeholder feedback on unfinished work to drive improvements.
  • Design and scope are progressively elaborated based on what is learned.
  • Helps manage uncertainty by testing ideas early and reducing rework risk.

Example

A project team drafts a basic user interface for a new claims portal, reviews it with end users, gathers comments, and then iterates to refine navigation, wording, and flow. This cycle continues until the design stabilizes, after which development proceeds with higher confidence.

PMP Example Question

Which scenario best reflects an iterative life cycle?

  1. The team builds a rough prototype, reviews it with stakeholders, and revises it repeatedly before completing the final design.
  2. The team delivers fully tested features to production at the end of each time-boxed sprint.
  3. The team defines complete requirements up front, then executes the plan once with minimal change.
  4. The team limits work in progress and pulls items through a continuous flow without time-boxes.

Correct Answer: A — Review and refinement of unfinished work through repeated cycles

Explanation: Iterative life cycles emphasize early feedback on partial outputs and repeated refinement before finalizing the solution.

ICS/OT Incident Response Drills and Exercises

An incident response plan is only a theory until the people who must use it have run it under pressure. This course helps OT engineers, operations leaders, IT responders, and security teams turn a plan on paper into a tested capability.

Define safe states and manual fallback before an incident forces the decision. Build escalation paths, tabletop exercises, and scenarios that expose the gaps a document review cannot find.

Then turn the results into evidence: an after-action report, owned improvements, recovery checks, and a drill cadence that keeps the program alive after the exercise ends.

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.
