Problem-Solver Pack — 8D + SPC Toolkits

Fixing the problem is half the job. Proving it stays fixed is the other half.

An 8D closes when the root cause is verified and the permanent corrective action is in place — but your customer's next question is always the same: how do you know it's still in control? That's the handover this pack is built around: the 8D workbook finds and fixes the root cause, and the control charts give you the ongoing evidence that the process holds the gain.

What's included

• 8D Problem-Solving Toolkit ($29 on its own). The full 8D method in one working Excel workbook: a complete D0–D8 report with a live progress tracker, three-legged root cause analysis (occurrence, detection/escape point and systemic — the way customers and auditors expect it), and built-in supporting tools: Is/Is-Not analysis, a 3-legged 5-Why and an Ishikawa (fishbone) canvas with a cause-evaluation table. Prevent-recurrence and read-across sections (PFMEA, control plan, lessons learned) close it out.
• SPC Control Chart Toolkit ($29 on its own). Every control chart you need in one pre-formatted workbook — X̄-R, X̄-S and I-MR for variable data plus switchable p/np/c/u attribute charts — with control limits that calculate automatically as you enter data, spec fields (USL / LSL / target) and a Start Here guide on which chart to use and how to read the signals. Plain Excel: no macros, no add-ins.

Why buy the pack

• The natural pairing: D7 prevent-recurrence hands over to the control chart — the 8D proves the fix, SPC proves it holds.
• 15% less than buying the two toolkits separately.
• Fill the yellow cells and the tools do the maths — no 8D theory or SPC formulas required.
• Instant download, secure checkout (Visa, Mastercard, PayPal).
• Single-organisation licence — every site, every user, no subscriptions.
• 14-day, no-questions full refund.

Who it's for

Quality and process engineers answering customer complaints, recurring defects and IATF 16949 / VDA 8D requests — who then need ongoing evidence of control for PPAP, audits and customer scorecards.

Learn the methods free first: the 8D Problem Solving masterclass and the Control Charts masterclass walk both methods in plain English, and the free Cpk Calculator and Fast Response Tracker are there to get you started.
