All Your Lean Tools in One Place

The Lean Tools dashboard gives you a unified view across all five tool types. Stat cards show counts for each 5 Whys, Ishikawa, Pareto, VSM, and KT and every analysis is listed with its type, status, owner, and last update. Filter by tool type, status, or search by keyword.

5 Whys - Find the Root Cause

Start with a problem statement and drill down through up to five "why" questions to reach the root cause. Each step shows the question and its answer in a clear chain, making it easy to follow the logic and share findings with the team. Link directly to ideas or actions once the root cause is identified.

Ishikawa — Fishbone Diagrams

Visualise cause and effect with interactive fishbone diagrams using the classic 6M categories: Man, Machine, Method, Material, Measure, and Environment. Causes are colour-coded by category and rendered as a full SVG diagram you can export to PDF. Star key causes to highlight them for follow-up.

Pareto — Focus on the Vital Few

Enter your data categories and counts, and OpExCore automatically generates a Pareto chart with the 80/20 line, cumulative percentages, and a clear breakdown of vital few versus trivial many. The "Where to Focus" summary tells you exactly which items to tackle first for the biggest impact.

Value Stream Mapping — See the Waste

Map your current-state processes step by step and instantly see total time, value-added time, wait time, and process efficiency. The visual process flow shows each step in sequence, while the efficiency bar highlights the split between value-added, non-value-added, and wait time at a glance.

KT Decision Analysis — Choose With Confidence

Compare alternatives using Kepner-Tregoe methodology with must-have criteria (Go/No Go) and weighted want criteria. Simple mode uses star ratings for quick decisions; Advanced mode provides full weighted scoring matrices. The recommended choice is highlighted automatically based on total points.
