Record iterations and developments

✅ Why this step protects quality as your design evolves

As your product develops, it changes. Features are added, issues resolved, constraints updated. If you don’t track those changes, quality suffers and alignment breaks.

This step is about recording design iterations, decisions, and updates—clearly and consistently. It’s essential for managing complexity, avoiding regression, and ensuring everyone is working from the same version.

Think of it as quality control for your thinking.

📘 What you’ll lock in

  • A clear record of what changed, why, and when
  • Visibility on who approved or actioned each change
  • A way to prevent old issues from resurfacing or rework from repeating
  • Confidence that your current design is the right one

🛠️ Tools and methods

  • Change Log Sheet

    Record updates with fields like date, change summary, file affected, reason, reviewer.

  • CAD Versioning & Save States

    Use consistent file naming (e.g. V1.2, V2.0 Final) and locking/tagging tools.

  • Meeting Minutes & Decisions Register

    Link key decisions to design changes—avoid “Who said that?” later.

  • Visual Snapshots

    Save screenshots or PDFs of changed views to illustrate impact.

  • Controlled File Access

    Use permissions to ensure only authorised versions are shared externally.

⚠️ Quality risks to avoid

  • Silent changes. Even small tweaks need a record—especially in CAD or firmware.
  • Losing history. If you can’t trace why something changed, you can’t defend the decision.
  • Overwriting finals. Always duplicate before major changes. Never edit the only copy.
  • Misaligned teams. If one team uses V1.3 and another V1.5, expect chaos.

💡 From real teams

“An old handle design reappeared in a prototype—because someone used a month-old file. We now log every release with a screenshot, reviewer, and issue ref.”

💡 Consider short changelogs in your drawings or CAD pack PDFs—it helps suppliers and QA spot deltas fast.

✍️ Quick self-check

  • Do we have a clear record of every major design iteration?
  • Can we explain what changed, why it changed, and who approved it?
  • Are all shared files up to date and correctly named?
  • Is QA or test feedback linked to design decisions and updates?

🎨 Visual concept (optional)

Illustration: A digital “Change Log” board with rows for change ID, description, affected part, and status. A team member reviews a CAD model with red-marked updates (“Moved boss”, “Increased rib depth”). Another person ticks off a checklist labeled “Release V2.1 Approved”.

Visual shows how tracking iterations helps teams protect quality, prevent confusion, and move forward with confidence.
