Forecasts you can trust. Planning that actually works.

I'm a supply chain professional with 5+ years in demand planning, machine-learning forecasting, and S&OP facilitation for FMCG leaders — turning data into decisions boards can act on.

What I do

From statistical forecasting to boardroom insights — across the full planning cycle.

01

Demand Planning & Forecasting

Statistical and ML forecasting for sales, promotions, and NPIs — with deep command of the KPIs that matter: FA, BIAS, FVA, MAPE.

02

S&OP Facilitation

Leading Demand Review Meetings and cross-functional planning across Sales, Marketing, Finance, and Supply — including insights for board members.

03

Inventory & Service Trade-offs

Managing stock-outs, overstock, and risks & opportunities — with a clear view of the logistics and distribution implications of every planning decision.

04

Transformation Projects

Design and implementation of planning software and processes (SAP IBP, Kinaxis) — from project vision through sprints, BIT, and go-live.

About me

I'm Monika Pieczonka — a supply chain expert who has seen planning from every angle: building ML forecasts, facilitating S&OP discussions, and delivering structured insights to board members and regional stakeholders.

I hold an MSc in Production Management and Engineering and an Eng. in Commodity Science from the Cracow University of Economics. My sweet spot is translating business needs to the IT world — and back — so transformation projects actually land.

Away from the spreadsheets, I run (first full marathon in 2024, half marathons since 2019), ride gravel and road bikes, and I'm training for my PPL(A) pilot licence.
