Starting S&OP: The First Ninety Days

Sebastian Bitter - Monday, June 29, 2026

The first ninety days decide whether an S&OP initiative sticks. A minimal viable process needs one product group, one monthly meeting, three people and one number. The recurring pitfalls are organisational rather than technical.

Value Streams and SCOR: Two Lenses on the Same Supply Chain

Sebastian Bitter - Thursday, June 25, 2026

Value streams (S2P, P2P, O2C) and SCOR are two established lenses on a supply chain. They overlap on the core flow (Plan ≈ S2P, Source + Make ≈ P2P, Deliver ≈ O2C), but set different accents. The differences show where each lens has its strengths.

Vertical Departments, Horizontal Value Stream: Why the Supply Chain Runs Across the Organisation

Sebastian Bitter - Wednesday, June 24, 2026

Companies are organised into departments. The supply chain runs across them. The same departments appear in multiple value streams. S&OP is the mechanism that makes the horizontal connections visible and manageable.

Re-Think Your Operating Model with AI

Oliver Grasl - Monday, June 22, 2026

S&OP is Not a Silo: How Sales & Operations Planning Fits Into the Value Streams of the Supply Chain

Sebastian Bitter - Monday, June 22, 2026

A supply chain can be broken down into value streams: Sense-to-Plan, Plan-to-Produce and Order-to-Cash. The S&OP process is part of the first one and a planning error in it propagates through the entire chain.

Strategy Mapping: The Missing Link Between Ambition and Execution

Burcu Bayram - Thursday, June 18, 2026

Strategies don't fail because the ideas are wrong. They fail because the connection between ambition and daily action breaks down. Strategy mapping makes this connection explicit, turning vision, goals, strategies, tactics and capabilities into a shared, navigable knowledge graph that the entire organization can read and act on.

Sales & Operations Planning: When the Plan Falls Apart

Sebastian Bitter - Monday, April 20, 2026

Disruptions are not the problem. Missing structure turns a disruption into a problem. The same disruption can be a catastrophe or a non-event depending on market conditions. Context decides.

Sales & Operations Planning: The Planning Matters More Than The Plan

Sebastian Bitter, Hieu Dang - Monday, March 23, 2026

No forecast is perfect and no order strategy wins every time. Companies that plan regularly are still better prepared for the unexpected. What matters is having a process that enables switching strategies when the situation changes.
