Impact Estimator

Slide the inputs and see roughly what the playbook I ran at Kothari Electronics could mean for your numbers. It's an estimate, not a promise, but it's built from real results.

How this estimate is calculated

This scenario uses fixed illustrative assumptions, rather than a forecast for your business. All amounts are in USD.

  • Sourcing: 8% of annual procurement spend.
  • Defects: spend × defect rate × 40% reduction × 15% cost factor.
  • Inventory: spend × 35% inventory-value proxy × carrying-cost rate × 15% reduction.
  • Vendors: $1,200 per vendor removed, assuming 10% consolidation rounded down.

The total adds these estimates. Savings can overlap; implementation costs and industry differences are not included.

From Mumbai
to Chicago

I grew up in my family's electronics business in Mumbai, where supply chain wasn't a subject. It was whether the shipment showed up and whether we got paid. Chasing vendors, negotiating rates, fixing stockouts: that was daily life long before I had textbook words for any of it.

The research came later: a year spent ranking 1,500 companies for India's first supply chain index. Then Chicago, for my MS at DePaul. These days I'm as happy writing SQL as I am on the phone with a supplier. I think that mix is the whole point.

How I Think About Supply Chain

Keep scrolling: one truck, one continuous 3D shot. It loads at the factory, stores at the warehouse, stocks the store, and ends at a customer's doorstep. The camera rides along.

Skip animation · Continue to writing ↓
Stop 01 · Manufacture

It starts on the
factory floor

Goods come off the line and onto the truck, the sourcing and production discipline behind ₹200K in FY24 procurement savings at Kothari Electronics.

Stop 02 · Store

Inventory finds
its home

Into the warehouse, onto the racks, buffer stock, reorder points and the MRP discipline that lifted material availability 30% at Mentone Concretes.

Stop 03 · Retail

Shelves meet
demand

Distribution puts product where the forecast says it sells: the demand-planning lens I apply from SKU-level data to national indices.

Stop 04 · Deliver

The last mile ends
at a doorstep

A parcel, a porch, a promise kept. Every link before it exists for this moment. That end-to-end view is how I approach supply chain.
