You know the waste is there. But—
Can't quantify which waste is the biggest
You sense the inefficiency, but can't see where costs accumulate. Without data, you can't prioritize.
Improvement efforts depend on individuals and don't last
Progress depends on one motivated person. When they move on, improvements stop. It's not systematized.
Want to change the floor, but can't convince management
Saying "there's waste" isn't enough. Without ROI numbers, management won't approve investment.
What are the 7+1 wastes?
Seven types of waste defined by the Toyota Production System (TPS). ROI Detective Agency adds an 8th waste — the waste of not measuring — to drive real improvement.
Over-processing
Doing more work than necessary. Excessive approval flows, unused reports, unnecessary meeting materials.
Inventory
Unused stock or stagnant information. Piled-up emails, neglected tasks, and unused data are all "inventory."
Overproduction
Producing more than needed. Creating unrequested documents, over-ordering stock, developing unused features.
Waiting
Waiting for approvals, replies, or system processing. Any time people or information are idle is waste.
Motion
Unnecessary movements. Repeated logins, searching for information, entering the same data in multiple places.
Transportation
Unnecessary transfers. Being passed between departments, endlessly forwarded emails, unnecessary business trips.
Defects
Rework due to mistakes. Fixing input errors, rebuilding due to misunderstood specs, handling complaints.
Not Measuring
Even if you sense waste, improvement can't begin without measurement. Not knowing where costs hide or how big they are — that is the greatest waste of all.

Our approach
We bring Toyota's "visualization" philosophy to life with data and technology.
Workflow visualization
Map your workflows and identify where the 7 wastes are hiding.
Measure & quantify waste
Turn vague inefficiency into numbers. Reveal exactly how much each type of waste is costing you.
Prioritization
Start with the highest-ROI improvements. We determine the order that maximizes impact with limited resources.
Monthly reports & improvement cycles
Monthly measurement, reporting, and proposals keep the PDCA cycle running. Not a one-time fix.
Where we can help
Accounting, HR & admin efficiency
Visualize waste in approval flows, manual input, and transcription to prioritize automation.
Sales & support improvement
Reduce waiting and over-processing waste in quoting, inquiries, and reporting to focus on core work.
IT & dev team productivity
Quantify overproduction (unneeded features) and waiting (review queues) to accelerate delivery.
Retail & service operations
Discover hidden waste in shift management, ordering, and service flows to improve labor costs and margins.
Internal workflow redesign
Reduce transportation and motion waste in internal approvals, expense reports, and attendance systems.
Systematize improvement activities
Transform ad-hoc improvements into a data-driven system that continues regardless of personnel changes.
